B. Background

1.0 Household Component

The Medical Expenditure Panel Survey (MEPS) provides nationally representative estimates of health care use, expenditures, sources of payment, and health insurance coverage for the U.S. civilian noninstitutionalized population. The MEPS Household Component (HC) also provides estimates of respondents’ health status, demographic and socio-economic characteristics, employment, access to care, and satisfaction with health care. Estimates can be produced for individuals, families, and selected population subgroups. The panel design of the survey, which includes 5 Rounds of interviews covering 2 full calendar years, provides data for examining person level changes in selected variables such as expenditures, health insurance coverage, and health status. Using computer assisted personal interviewing (CAPI) technology, information about each household member is collected, and the survey builds on this information from interview to interview. All data for a sampled household are reported by a single household respondent.

The MEPS-HC was initiated in 1996. Each year a new panel of sample households is selected. Because the data collected are comparable to those from earlier medical expenditure surveys conducted in 1977 and 1987, it is possible to analyze long-term trends. Each annual MEPS-HC sample size is about 15,000 households. Data can be analyzed at either the person or event level. Data must be weighted to produce national estimates.

The set of households selected for each panel of the MEPS HC is a subsample of households participating in the previous year’s National Health Interview Survey (NHIS) conducted by the National Center for Health Statistics. The NHIS sampling frame provides a nationally representative sample of the U.S. civilian noninstitutionalized population and reflects an oversample of Blacks and Hispanics. In 2006, the NHIS implemented a new sample design, which included Asian persons in addition to households with Black and Hispanic persons in the oversampling of minority populations. The linkage of the MEPS to the previous year’s NHIS provides additional data for longitudinal analytic purposes.

2.0 Medical Provider Component

Upon completion of the household CAPI interview and obtaining permission from the household survey respondents, a sample of medical providers are contacted by telephone to obtain information that household respondents can not accurately provide. This part of the MEPS is called the Medical Provider Component (MPC) and information is collected on dates of visits, diagnosis and procedure codes, charges and payments. The Pharmacy Component (PC), a subcomponent of the MPC, does not collect charges or diagnosis and procedure codes but does collect drug detail information, including National Drug Code (NDC) and medicine name, as well as date filled and sources and amounts of payment. The MPC is not designed to yield national estimates. It is primarily used as an imputation source to supplement/replace household reported expenditure information.

Return To Table Of Contents

3.0 Survey Management and Data Collection

MEPS HC and MPC data are collected under the authority of the Public Health Service Act. Data are collected under contract with Westat, Inc. (MEPS HC) and Research Triangle Institute (MEPS MPC). Data sets and summary statistics are edited and published in accordance with the confidentiality provisions of the Public Health Service Act and the Privacy Act. The National Center for Health statistics (NCHS) provides consultation and technical assistance.

As soon as data collection and editing are completed, the MEPS survey data are released to the public in staged releases of summary reports, micro data files, and tables via the MEPS Web site: meps.ahrq.gov. Selected data can be analyzed through MEPSnet, an on-line interactive tool designed to give data users the capability to statistically analyze MEPS data in a menu-driven environment.

Additional information on MEPS is available from the MEPS project manager or the MEPS public use data manager at the Center for Financing, Access, and Cost Trends, Agency for Healthcare Research and Quality, 5600 Fishers Lane, Rockville, MD 20857 (301-427-1406).

C. Technical and Programming Information

1.0 General Information

This documentation describes the 2014 full-year consolidated data file from the Medical Expenditure Panel Survey Household Component (MEPS HC). Released as an ASCII file (with related SAS, Stata, and SPSS programming statements and data user information) and a SAS transport dataset, this public use file provides information collected on a nationally representative sample of the civilian noninstitutionalized population of the United States for calendar year 2014. The file contains 1,838 variables and has a logical record length of 5,398 with an additional 2-byte carriage return/line feed at the end of each record.

This file consists of MEPS survey data obtained in Rounds 3, 4, and 5 of Panel 18 and Rounds 1, 2, and 3 of Panel 19, the rounds for the MEPS panels covering calendar year 2014, and contains variables pertaining to survey administration, demographics, income, person-level conditions, health status, disability days, quality of care, employment, health insurance, and person-level medical care use and expenditures.

The following documentation offers a brief overview of the types and levels of data provided, content and structure of the files, and programming information. It contains the following sections:

Data File Information
Survey Sample Information
Variable-Source Crosswalk

Both weighted and unweighted frequencies of most variables included in the 2014 full-year consolidated data file are provided in the accompanying codebook file. The exceptions to this are weight variables and variance estimation variables. Only unweighted frequencies of these variables are included in the accompanying codebook file. See the Weights Variables list in Section D, Variable-Source Crosswalk.

A database of all MEPS products released to date and a variable locator indicating the major MEPS data items on public use files that have been released to date can be found at the following link on the MEPS Web site: meps.ahrq.gov.

2.0 Data File Information

This public use dataset contains variables and frequency distributions associated with 34,875 persons who participated in the MEPS Household Component of the Medical Expenditure Panel Survey in 2014. These persons received a positive person-level weight, a family-level weight, or both (some participating persons belonged to families characterized as family-level nonrespondents while some members of participating families were not eligible for a person-level weight).

These 34,875 persons were part of one of the two MEPS panels for whom data were collected in 2014: Rounds 3, 4, and 5 of Panel 18 or Rounds 1, 2, and 3 of Panel 19. Of these persons, 33,162 were assigned a positive person-level weight. There were 13,421 families receiving a positive family-level weight. The codebook provides both weighted and unweighted frequencies for most variables on the dataset. In conjunction with the person-level weight variable (PERWT14F) provided on this file, data for persons with a positive person-level weight can be used to make estimates for the civilian noninstitutionalized U.S. population for 2014.

2.4 Variable Naming

In general, variable names reflect the content of the variable, with an eight-character limitation. Edited variables end in an X and are so noted in the variable label. The last two characters in round-specific variables denote the rounds of data collection, Round 3, 4, or 5 of Panel 18 and Round 1, 2, or 3 of Panel 19. Unless otherwise noted, variables that end in “14” represent status as of December 31, 2014.

Variables contained in this delivery were derived either from the questionnaire itself or from the CAPI. The source of each variable is identified in the section of the documentation entitled “Section D. Variable-Source Crosswalk.” Sources for each variable are indicated in one of four ways: (1) variables derived from CAPI or assigned in sampling are so indicated; (2) variables derived from complex algorithms associated with reenumeration are labeled “RE Section”; (3) variables that are collected by one or more specific questions in the instrument have those question numbers listed in the Source column; and (4) variables constructed from multiple questions using complex algorithms are labeled “Constructed.”

2.5 File Contents

Users of MEPS data should be aware that the survey collects data for all sample persons who were in the survey target population at any time during the survey period. In other words, a small proportion of individuals in MEPS analytic files are not members of the survey target population (i.e., civilian noninstitutionalized) for the entire survey period. These persons include those who had periods during which they lived in an institution (e.g., nursing home or prison), were in the military, or lived out of the country, as well as those who were born (or adopted) into MEPS sample households or died during the year. They are considered sample persons for the survey and are included in MEPS data files with positive person weights, but no data were collected for the periods they were not inscope and their annual data for variables like health care utilization, expenditures, and insurance coverage reflect only the part of the year they were inscope for the survey. Persons who are inscope for only part of the year should not be confused with non-respondents. Sample persons who are classified as non-respondents to one or more rounds of data collection (i.e., initial non-respondents and drop-outs over time) are not included in MEPS annual files, and survey weights for full-year respondents are inflated through statistical adjustment procedures to compensate for both full and part-year nonresponse (see Section 3.0 “Survey Sample Information” for more information). For more details about the identification and analytic considerations regarding sample persons who are inscope only part of the year, see meps.ahrq.gov/about_meps/hc_sample.shtml.

2.5.1 Survey Administration Variables (DUID-RURSLT53)

The survey administration variables contain information related to conducting the interview, household and family composition, and person-level and RU-level status codes. Data for the survey administration variables were derived from the sampling process, the CAPI programs, or were computed based on information provided by the respondent in the reenumeration section of the questionnaire. Most survey administration variables on this file are asked during every round of the MEPS interview. They describe data for Rounds 3/1, 4/2, 5/3 status and status as of December 31, 2014. Variable names ending in “xy” represent variables relevant to Round “x” of Panel 18 or Round “y” of Panel 19. For example, RULETR53 is a variable relevant to Round 5 of Panel 18 or Round 3 of Panel 19, depending on the panel in which the person was included. The variable PANEL indicates the panel in which the person participated.

The December 31, 2014 variables were developed in two ways. Those used in the construction of eligibility, inscope, and the end reference date were based on an exact date. The remaining variables were constructed using data from specific rounds, if available. If data were missing from the target round but were available in another round, data from that other round were used in the variable construction. If no valid data were available during any round of data collection, an appropriate reserved code was assigned.

Dwelling Units, Reporting Units, and Families

The definitions of Dwelling Units (DUs) in the MEPS Household Survey are generally consistent with the definitions employed for the National Health Interview Survey (NHIS). The Dwelling Unit ID (DUID) is a five-digit random ID number assigned after the case was sampled for MEPS. A person number (PID) uniquely identifies each person within the DU. The variable DUPERSID is the combination of the variables DUID and PID.

PANEL is a constructed variable used to specify the panel number for the person. PANEL will indicate either Panel 18 or Panel 19 for each person on the file. Panel 18 is the panel that started in 2013, and Panel 19 is the panel that started in 2014.

A Reporting Unit (RU) is a person or group of persons in the sampled DU who are related by blood, marriage, adoption, foster care, or other family association. Each RU was interviewed as a single entity for MEPS. Thus, the RU serves chiefly as a family-based “survey” operations unit rather than an analytic unit. Members of each RU within the DU are identified in the pertinent three rounds by the round-specific variables RULETR31, RULETR42, and RULETR53. End-of-year status (as of December 31, 2014 or the last round they were in the survey) is indicated by the RULETR14 variable. Regardless of the legal status of their association, two persons living together as a “family” unit were treated as a single RU if they chose to be so identified.

Examples of different types of RUs are:

A married daughter and her husband living with her parents in the same DU constitute a single RU;
A husband and wife and their unmarried daughter, age 18, who is living away from home while at college constitute two RUs; and
Three unrelated persons living in the same DU would each constitute a distinct RU (a total of three RUs).

Unmarried college students (less than 24 years of age) who usually live in the sampled household but were living away from home and going to school at the time of the Round 3/1 MEPS interview were treated as an RU separate from that of their parents for the purpose of data collection.

The round-specific variables RUSIZE31, RUSIZE42, RUSIZE53, and the end-of-year status variable RUSIZE14 indicate the number of persons in each RU, treating students as single RUs separate from their parents. Thus, students are not included in the RUSIZE count of their parents’ RU. However, for many analytic objectives, the student RUs would be combined with their parents’ RU, treating the combined entity as a single family. Family identifier and size variables are described below and include students with their parents’ RU.

The round-specific variables FAMID31, FAMID42, FAMID53, and the end-of-year status variable FAMID14 identify a family (i.e., persons related to one another by blood, marriage, adoption, foster care, or self-identified as a single unit) for each round and as of December 31, 2014. The FAMID variables differ from the RULETR variables only in that student RUs are combined with their parents’ RU.

Two other family identifiers, FAMIDYR and CPSFAMID, are provided on this file. The annualized family ID letter, FAMIDYR, identifies eligible members of the eligible annualized families within a DU. The CPSFAMID represents a redefinition of MEPS families into families defined by the Current Population Survey (CPS). Some of the distinctions between CPS-and MEPS-defined families are that MEPS families include and CPS families do not include: non-married partners, foster children, and in-laws. These persons are considered as members of separate families for CPS-like families. CPS-like families are defined so a poverty status classification variable consistent with established definitions of poverty can be assigned to the CPS-like families and used for weight poststratification purposes. In order to identify a person’s family affiliation, users must create a unique set of FAMID variables by concatenating the DU identifier and the FAMID variable. Instructions for creating family estimates are described in Section 3.5.

The round-specific variables FAMSZE31, FAMSZE42, FAMSZE53, and the end-of-year status variable FAMSZE14 indicate the number of persons associated with a single family unit after students are linked to their associated parent RUs for analytical purposes. Family-level analyses should use the FAMSZE variables.

Note that the variables RUSIZE31, RUSIZE42, RUSIZE53, RUSIZE14, FAMSZE31, FAMSZE42, FAMSZE53, and FAMSZE14 exclude persons who are ineligible for data collection (i.e., those where ELGRND31 NE 1, ELGRND42 NE 1, ELGRND53 NE 1 or ELGRND14 NE 1); analysts should exclude ineligible persons in a given round from all family-level analyses for that round.

The round-specific variables RURSLT31, RURSLT42, and RURSLT53 indicate the RU response status for each round. Users should note that the values for RURSLT31 differ from those for RURSLT42 and RURSLT53. The values for RURSLT31 include the following:

Standard or primary RUs are the original RUs from NHIS. A new RU is one created when members of the household leave the primary RU and are followed according to the rules of the survey. A student RU is an unmarried college student (under 24 years of age) who is considered a usual member of the household, but was living away from home while going to school, and was treated as a Reporting Unit (RU) separate from his or her parents’ RU for the purpose of data collection. RUCLAS14 was set based on the RUCLAS values from Rounds 3/1, 4/2, and 5/3. If the person was present in the responding RU in Round 5/3, then RUCLAS14 was set to RUCLAS53. If the person was not present in a responding RU in Round 5/3 but was present in Round 4/2, then RUCLAS14 was set to RUCLAS42. If the person was not present in either Rounds 4/2 or 5/3 but was present in Round 3/1, then RUCLAS14 was set to RUCLAS31. If the person was not linked to a responding RU during any round, then RUCLAS14 was set to -9.

Geographic Variables

The round-specific variables REGION31, REGION42, REGION53, and the end-of-year status variable REGION14 indicate the Census region for the RU. REGION14 indicates the region for the 2014 portion of Round 5/3. For most analyses, REGION14 should be used.

The values and states for each region include the following:
Value	Label	States
1	Northeast	Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont
2	Midwest	Indiana, Illinois, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin
3	South	Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia
4	West	Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming

Reference Period Dates

The reference period is the period of time for which data were collected in each round for each person. The reference period dates were determined during the interview for each person by the CAPI program. The round-specific beginning reference period dates are included for each person. These variables include BEGRFM31, BEGRFY31, BEGRFM42, BEGRFY42, BEGRFM53, and BEGRFY53. The reference period for Round 1 for most persons began on January 1, 2014 and ended on the date of the Round 1 interview. For RU members who joined later in Round 1, the beginning Round 1 reference date was the date the person entered the RU. For all subsequent rounds, the reference period for most persons began on the date of the previous round’s interview and ended on the date of the current round’s interview. Persons who joined after the previous round’s interview had their beginning reference date for the round set to the day they joined the RU.

The round-specific ending reference period dates for Rounds 3/1, 4/2, and 5/3 as well as the end-of-year reference period end date variables are also included for each person. These variables include ENDRFM31, ENDRFY31, ENDRFM42, ENDRFY42, ENDRFM53, ENDRFY53, ENDRFM14, and ENDRFY14. For most persons in the sample, the date of the round’s interview is the reference period end date. Note that the end date of the reference period for a person is prior to the date of the interview if the person was deceased during the round, left the RU, was institutionalized prior to that round’s interview, or left the RU to join the military.

Please note that in prior years the day of the date variables were included. Starting with the FY 2013 Consolidated data file, for confidentiality reasons, the day variables are no longer included.

Reference Person Identifiers

The round-specific variables REFPRS31, REFPRS42, and REFPRS53 and the end-of-year status variable REFPRS14 identify the reference person for Rounds 3/1, 4/2 and 5/3, and as of December 31, 2014 (or the last round they were in the survey). In general, the reference person is defined as the household member 16 years of age or older who owns or rents the home. If more than one person meets this description, the household respondent identifies one from among them. If the respondent is unable to identify a person fitting this definition, the questionnaire asks for the head of household and this person is then considered the reference person for that RU. This information is collected in the Reenumeration section of the CAPI questionnaire.

The respondent is the person who answered the interview questions for the Reporting Unit (RU). The round-specific variables RESP31, RESP42, and RESP53 and the end-of-year status variable RESP14 identify the respondent for Rounds 3/1, 4/2, and 5/3 and as of December 31, 2014 (or the last round they were in the survey). Only one respondent is identified for each RU. In instances where the interview was completed in more than one session, only the first respondent is indicated.

There are two types of respondents. The respondent can be either an RU member or a non-RU member proxy. The round-specific variables PROXY31, PROXY42, and PROXY53 and the end-of-year status variable PROXY14 identify the type of respondent for Rounds 3/1, 4/2, 5/3 and as of December 31, 2014 (or the last round they were in the survey).

Language of Interview

The language of interview variable (INTVLANG) is a summary value of the round-specific RU-level information section question, (RS02), which asks the interviewer to record the language in which the interview was completed: English, Spanish, Both English and Spanish, Other Language. Given the first round that the person was part of the study and the person’s associated RU for that round, INTVLANG is assigned the interview language value reported for the person’s RU for the round.

Person Status

A number of variables describe the various components reflecting each person’s status for each round of data collection. These variables provide information about a person’s in-scope status, Keyness status, eligibility status, and disposition status. These variables include: KEYNESS, INSCOP31, INSCOP42, INSCOP53, INSCOP14, INSC1231, INSCOPE, ELGRND31, ELGRND42, ELGRND53, ELGRND14, PSTATS31, PSTATS42, and PSTATS53. These variables are set based on sampling information and responses provided in the reenumeration section of the CAPI questionnaire.

Through the reenumeration section of the CAPI questionnaire, each member of a RU was classified as “Key” or “Non-Key”, “in-scope” or “out-of-scope”, and “eligible” or “ineligible” for MEPS data collection. To be included in the set of persons used in the derivation of MEPS person-level estimates, a person had to be a member of the civilian noninstitutionalized population for at least one day during 2014. Because a person’s eligibility for the survey might have changed since the NHIS interview, a sampling reenumeration of household membership was conducted at the start of each round’s interview. Only persons who were “inscope” sometime during the year, were “Key”, and responded for the full period in which they were inscope were assigned positive person-level weights and thus are to be used in the derivation of person-level national estimates from the MEPS.

Note: If analysts want to subset to infants born during 2014, then newborns should be identified using AGE14X = 0 rather than PSTATSxy = 51.

Inscope

The round-specific variables INSCOP31, INSCOP42, and INSCOP53 indicate a person’s in-scope status for Rounds 3/1, 4/2, and 5/3. INSCOP14, INSC1231, and INSCOPE indicate a person’s in-scope status for the portion of Round 5/3 that covers 2014, the person’s in-scope status as of 12/31/14, and whether a person was ever in-scope during the calendar year 2014. A person was considered as in-scope during a round or a referenced time period if he or she was a member of the U.S. civilian, noninstitutionalized population at some time during that round or that time period. The values of these variables taken in conjunction allow one to determine in-scope status over time (for example, becoming inscope in the middle of a round, as would be the case for newborns).

These variables may contain the following values and corresponding labels:
Value	Definition
0	Incorrectly listed, or on NHIS roster but out-of-scope prior to January 1, 2014
1	Person is inscope for the whole reference period
2	Person is inscope at the start of the RU reference period, but not at the end of the RU reference period
3	Person is not inscope at the start of RU reference period, but is inscope at the end of the RU reference period. (For example, the person is inscope from the date the person joined the RU or the person was in the military in the previous round, but is no longer in the military in the current round)
4	Person is inscope during the reference period, but neither at the reference start date nor on the reference end date. (For example, person leaves an institution, goes into community, and then dies)
5	Person is out-of-scope for all of the reference period during which he or she is an RU member. (For example, the person is in the military)
6	Person is out-of-scope for the entire reference period and is not a member of the RU during this time period and was inscope and an RU member in an earlier round
7	Person is not in an RU, joined in a later round (or joined the RU after December 31, 2014 for INSCOP14)
8	RU Non-response and Key persons who left an RU with no tracing info and so a new RU was not formed
9	Person is not a member of an RU during this time period, and was an RU member in an earlier round

Keyness

The term “Keyness” is related to an individual’s chance of being included in MEPS. A person is Key if that person is linked for sampling purposes to the set of NHIS sampled households designated for inclusion in MEPS. Specifically, a Key person was either a member of a responding NHIS household at the time of interview, or joined a family associated with such a household after being out-of-scope at the time of the NHIS (examples of the latter situation include newborns and those returning from military service, an institution, or residence in a foreign country).

A non-Key person is one whose chance of selection for the NHIS (and MEPS) was associated with a household eligible but not sampled for the NHIS and who later became a member of a MEPS Reporting Unit. MEPS data (e.g., utilization and expenditures) were collected for the period of time a non-Key person was part of the sampled unit to provide information for family-level analyses. However, non-Key persons who leave a sample household unaccompanied by a Key, in-scope member were not followed for subsequent interviews. Non-Key individuals do not receive sample person-level weights and thus do not contribute to person-level national estimates.

The variable KEYNESS indicates a person’s Keyness status. This variable is not round-specific. Instead, it is set at the time the person enters MEPS, and the person’s Keyness status never changes. Once a person is determined to be Key, that person will always be Key.

It should be pointed out that a person might be Key even though not part of the civilian, noninstitutionalized portion of the U.S. population. For example, a person in the military may have been living with his or her civilian spouse and children in a household sampled for NHIS. The person in the military would be considered a Key person for MEPS; however, such a person would not be eligible to receive a person-level sample weight if he or she was never inscope during 2014.

Eligibility

The eligibility of a person for MEPS pertains to whether or not data were to be collected for that person. All of the Key in-scope persons of a sampled RU were eligible for data collection. The only non-Key persons eligible for data collection were those who happened to be living in an RU with at least one Key, in-scope person. Their eligibility continued only for the time that they were living with at least one such person. The only out-of-scope persons eligible for data collection were those who were living with Key in-scope persons, again only for the time they were living with such a person. Only military persons can meet this description (for example, a person on full-time active duty military, living with a spouse who is Key).

A person may be classified as eligible for an entire round or for some part of a round. For persons who are eligible for only part of a round (for example, persons may have been institutionalized during a round), data were collected for the period of time for which that person was classified as eligible. The round-specific variables ELGRND31, ELGRND42, ELGRND53 and the end-of-year status variable ELGRND14 indicate a person’s eligibility status for Rounds 3/1, 4/2, and 5/3 and as of December 31, 2014.

Person Disposition Status

The round-specific variables PSTATS31, PSTATS42, and PSTATS53 indicate a person’s response and eligibility status for each round of interviewing. The PSTATSxy variables indicate the reasons for either continuing or terminating data collection for each person in the MEPS. Using this variable, one could identify persons who moved during the reference period, died, were born, institutionalized, or who were in the military. Analysts should note that PSTATS53 provides a summary for all of Round 5/3, including transitions that occurred after 2014. Note that some categories may be collapsed for confidentiality purposes.

The following codes specify the value labels for the PSTATSxy variables.

2.5.2 Navigating the MEPS Data with Information on Person Disposition Status

Since the variables PSTATS31, PSTATS42, and PSTATS53 indicate the reasons for either continuing or terminating data collection for each person in MEPS, these variables can be used to explain the beginning and ending dates for each individual’s reference period of data collection, as well as which sections in the instrument each individual did not receive. By using the information included in the following table, analysts will be able to determine for each individual which sections of the MEPS questionnaire collected data elements for that person.

Some individuals have a reference period that spans an entire round, while other individuals may have data collected only for a portion of the round. When an individual’s reference period does not coincide with the RU reference period, the individual’s start date may be a later date, or the end date may be an earlier date, or both. In addition, some individuals have reference period information coded as “Inapplicable” (e.g., for individuals who were not actually in the household). The information in this table indicates the beginning and ending dates of reference periods for persons with various values of PSTATS31, PSTATS42, and PSTATS53. The actual dates for each individual can be found in the following variables included on this file: BEGRFM31, BEGRFM42, BEGRFM53, BEGRFY31, BEGRFY42, BEGRFY53, ENDRFM31, ENDRFM42, ENDRFM53, ENDRFY31, ENDRFY42, ENDRFY53, ENDRFM14, and ENDRFY14.

The table below also describes the section or sections of the questionnaire that were NOT asked for each value of PSTATS31, PSTATS42, and PSTATS53. For example, the Condition Enumeration (CE) and Preventive Care (AP) sections have questions that are not asked for deceased persons. The Closing (CL) section also contains some questions or question rosters (see CL07A, CL35 through CL37, CL48 through CL50, CL54, CL58, and CL64) that exclude certain persons depending on whether the person died, became institutionalized, or otherwise left the RU; however, no one is considered to have skipped the entire section. Some questions or sections (e.g., Health Status (HE), Employment (RJ, EM, EW)) are skipped if individuals are not within a certain age range. Since the PSTATS variables do not address skip patterns based on age, analysts will need to use the appropriate age variables.

The paper-and-pencil Self-Administered Questionnaire (SAQ) was designed to collect information based on two age categories during Panel 19 Round 2 and Panel 18 Round 4. A person was considered eligible to receive an SAQ if that person did not have a status of deceased or institutionalized, did not move out of the U.S. or to a military facility, was not a non-response at the time of the Round 2 or Round 4 interview date, and was 18 years of age or older. No RU members added in Round 3 or Round 5 were asked to complete an SAQ questionnaire. Because PSTATS variables do not address skip patterns based on age, this questionnaire was not included in the table below. Once again, analysts will need to use the appropriate age variable which in this case would be AGE42X. The documentation for this questionnaire appears in the SAQ section of this document under “Health Status Variables.”

Please note that the end reference date shown below for PSTATS53 reflects the Round 5/3 reference period rather than the portion of Round 5/3 that occurred during 2014.

2.5.3 Demographic Variables (AGE31X-DAPID53X)

General Information

Demographic variables provide information about the demographic characteristics of each person from the MEPS-HC. The characteristics include age, sex, race, ethnicity, marital status, educational attainment, and military service. As noted below, some variables have edited and imputed values. Most demographic variables on this file were asked during every round of the MEPS interview. These variables describe data for Rounds 3, 4, and 5 of Panel 18 (the panel that started in 2013); Rounds 1, 2 and 3 of Panel 19 (the panel that started in 2014); and status as of December 31, 2014. Demographic variables that are round-specific are identified by names including numbers “xy”, where x and y refer to round numbers of Panel 18 and Panel 19 respectively. For example, AGE31X represents the age data relevant to Round 3 of Panel 18 or Round 1 of Panel 19. As mentioned in Section 2.5.1 “Survey Administration Variables”, the variable PANEL indicates the panel from which the data were derived. A value of 18 indicates Panel 18 data and a value of 19 indicates Panel 19 data. The remaining demographic variables on this file are not round-specific.

The variables describing demographic status of the person as of December 31, 2014 were developed in two ways. First, the age variable (AGE14X) represents the exact age, calculated from date of birth and indicates age status as of 12/31/14. For the remaining December 31^st variables [i.e., related to marital status (MARRY14X, SPOUID14, SPOUIN14), student status (FTSTU14X), and the relationship to reference persons (REFRL14X)], the following algorithm was used: data were taken from the Round 5/3 counterpart if non-missing; else, if missing, data were taken from the Round 4/2 counterpart; else from the Round 3/1 counterpart. If no valid data were available during any of these rounds of data collection, the algorithm assigned the missing value (other than -1 “Inapplicable”) from the first round that the person was part of the study. When all three rounds were set to –1, a value of –9 “Not Ascertained” was assigned.

Age

Date of birth and age for each RU member were asked or verified during each MEPS interview (DOBMM, DOBYY, AGE31X, AGE42X, AGE53X). If date of birth was available, age was calculated based on the difference between date of birth and date of interview. Inconsistencies between the calculated age and the age reported during the CAPI interview were reviewed and resolved. For purposes of confidentiality, the variables AGE31X, AGE42X, AGE53X, AGE14X, and AGELAST were top-coded at 85 years.

When date of birth was not provided but age was provided (either from the MEPS interviews or the 2012-2013 NHIS data), the month and year of birth were assigned randomly from among the possible valid options. For any cases still not accounted for, age was imputed using:

the mean age difference between MEPS participants with certain family relationships (where available) or
the mean age value for MEPS participants.

For example, a mother’s age is imputed as her child’s age plus 26, where 26 is the mean age difference between MEPS mothers and their children. A wife’s age is imputed as the husband’s age minus 3, where 3 is the mean age difference between MEPS wives and husbands.

Age was imputed in this way for 28 persons on this file. Age was determined for 16 additional persons from data in a later round.

AGELAST indicates a person’s age from the last time the person was eligible for data collection during a specific calendar year. The age range for this variable is between 0 and 85.

Sex

Data on the gender of each RU member (SEX) were initially determined from the 2012 NHIS for Panel 18 and from the 2013 NHIS for Panel 19. The SEX variable was verified and, if necessary, corrected during each MEPS interview. The data for new RU members (persons who were not members of the RU at the time of the NHIS interviews) were also obtained during each MEPS round. When gender of the RU member was not available from the NHIS interviews and was not ascertained during one of the subsequent MEPS interviews, it was assigned in the following way. The person’s first name was used to assign gender if obvious (no cases were resolved in this way). If the person’s first name provided no indication of gender, then family relationships were reviewed (no cases were resolved this way). If neither of these approaches made it possible to determine the individual’s gender, gender was randomly assigned (one case was resolved this way).

Race and Ethnicity Group

The race and the ethnic background questions were asked for each RU member during the MEPS interview. If the information was not obtained in Round 1, the questions were asked in subsequent rounds. It should be noted that race/ethnicity questions in the MEPS were revised starting with data collection in 2013 for Panel 16 Round 5, Panel 17 Round 3, and Panel 18 Round 1; this affected data starting with the FY 2012 file. Previously, there were two race questions, but starting with data collection in 2013, there is only one race question. All Asian categories listed in the second question were moved to the new single question. In addition, the new race question had additional detail for the Native Hawaiian and Other Pacific Islander categories. The main change for ethnicity is that the new questions allowed respondents to report more than one Hispanic ethnicity. Race/ethnicity data from earlier years may not be directly comparable. The following table shows the variables used for FY 2002-2011 and FY 2012-2014, with these exceptions: 1) in FY 2012, RACEV1X categories 4 and 5 were not combined but are combined since 2013, and 2) RACEV2X and HISPNCAT were first introduced in 2013. See a detailed description below.

Race and ethnicity variables and their values for years prior to 2002 are available in the documentation for the FY Consolidated PUF for each data year.

Values for these variables were obtained based on the following priority order. If available, data collected were used to determine race and ethnicity. If race and/or ethnicity were not reported in the interview, then data obtained from the originally collected NHIS data were used. If still not ascertained, the race, and/or ethnicity were assigned based on relationship to other members of the DU using a priority ordering that gave precedence to blood relatives in the immediate family (this approach was used on 23 persons to set race and 16 persons to set ethnicity).

For the FY12 and FY13 PUFs, three new race variables were constructed for both the old and the new questions: RACEVER, RACEV1X, and RACETHX. The new variable, RACEVER, was constructed to indicate which race version questions were asked. In 2013, the old questions were asked for Panel 17 Rounds 1 and 2, and the new questions were asked for Panel 17 Rounds 3 to 5 and Panel 18 Rounds 1 to 3. RACEVER was included in only the 2012 and 2013 FY PUFs. RACEVER has been dropped for future PUFs. The variables RACEV1X and RACETHX replace the variables RACEX and RACETHNX from 2002-2011. A new race variable, RACEV2X, was constructed only for the new race question and was added for the first time to the 2013 files. This variable continues to be constructed and includes the expanded detail Asian categories. Contrary to RACEV1X, a person with multiple Asian races selected will be considered multiple races for RACEV2X. RACEV2X was set to -1 “Inapplicable” for persons that were not asked the new race question in FY13 only. The other specific race categories RACEAX, RACEBX, and RACEWX continue to be constructed for all PUFs.

For the FY12 and FY13 PUFs, the two Hispanic ethnicity variables from previous years were included: HISPANX and HISPCAT. The HISPANX variable continues to be constructed as usual. The HISPCAT variable was constructed for specific Hispanic categories based only on the old question in FY12 and FY13. HISPCAT has been dropped for future FY PUFs. A new ethnicity variable, HISPNCAT, based on the new question, was introduced starting with 2012. HISPNCAT includes similar categories as HISPCAT but in a different order, and contains an additional category, 8 “Multiple Hispanic Groups Reported”, to represent any multiple responses reported. This variable continues to be constructed for all PUFs. HISPNCAT was set to -1 “Inapplicable” for persons that were not asked the new ethnicity question in FY12 and FY13 only.

Please note that starting with the 2013 Use file, categories have been collapsed in the variables RAVEV1X, RACEV2X and HISPNCAT. For RACEV1X, categories 4 and 5 were collapsed in category 4 as “ASIAN/NATV HAWAIIAN/PACFC ISL-NO OTH”. For RACEV2X, categories 7, 8, 9, 10, and 11 were collapsed in category 10 as “OTH ASIAN/NATV HAWAIIAN/PACFC ISL-NO OTH,” and for HISPNCAT, categories 6 and 7 were collapsed in category 6 as “OTH LAT AM/HISP/LATINO/SPNSH ORGN-NO OTH”.

Language and English Proficiency

In 2013, three questions were added to the Demographic section to ascertain how well a person speaks English; they replaced the preferred language questions that had been asked in the Access to Care section in Rounds 2 and 4 from 2002 to 2012.

All households were first asked whether anyone age 5 and above in their family spoke a language other than English at home (RE102, OTHLANG). If the response to OTHLANG was ‘yes’, LANGSPK (RE102A) indicates whether a person spoke Spanish or some other language at home. HWELLSPE (RE102B) indicates how well a person who lives in a family where someone speaks some other language at home, speaks English.

These questions were asked of everyone in Round 1, except deceased and institutionalized persons. OTHLANG was also asked of new persons in Rounds 2 to 5, and if they reported speaking a language other than English at home, they were asked what language they speak at home and how well they speak English. However, OTHLANG and LANGSPK were set to -1 “Inapplicable” for any new persons in Rounds 2 to 5, and HWELLSPE was set to the appropriate value.

Starting with the 2014 Use PUF file, the Access to Care variables LANGHM42, ENGCMF42, ENGSPK42 have been dropped.

Foreign Born Status

In FY 2013, three foreign born questions were asked in the Demographic section to ascertain whether a person was born in the U.S. (RE102C), what year they came to the U.S. (RE102D) if not born in the U.S., and years lived in the U.S. (RE102E) if the response to RE102D was ‘Don’t Know’. They replaced similar questions that had been asked in the Access to Care section.

The three foreign born questions were only asked once for each eligible person, that is, the first round the person was interviewed. These new questions were asked of everyone, except deceased and institutionalized persons. The data from RE102D and RE102E were used to calculate the number of years a person has lived in the U.S. for the constructed variable, YRSINUS. The data from RE102C are reported as the constructed variable BORNUSA.

Starting with the 2014 Use PUF file, USBORN42, USLIVE42, and LIVEUS42 have been dropped.

Marital Status and Spouse ID

Current marital status was collected and/or updated during every round of the MEPS interview. This information was obtained in RE13 and RE97 and is reported as MARRY31X, MARRY42X, MARRY53X, and MARRY14X. Persons under the age of 16 were coded as 6 “Under 16 – Inapplicable”. If marital status of a specified round differed from that of the previous round, then the marital status of the specified round was edited to reflect a change during the round (e.g., married in round, divorced in round, separated in round, or widowed in round).

In instances where there were discrepancies between the marital statuses of two individuals within a family, other person-level variables were reviewed to determine the edited marital status for each individual. Thus, when one spouse was reported as married and the other spouse reported as widowed, the data were reviewed to determine if one partner should be coded as 8 “Widowed in Round”.

Edits were performed to ensure some consistency across rounds. First, a person could not be coded as “Never Married” after previously being coded as any other marital status (e.g., “Widowed”). Second, a person could not be coded as “Under 16 – Inapplicable” after being previously coded as any other marital status. Third, a person could not be coded as “Married in Round” after being coded as “Married” in the round immediately preceding. Fourth, a person could not be coded as an “in Round” code (e.g., “Widowed in Round”) in two subsequent rounds. Since marital status can change across rounds and it was not feasible to edit every combination of values across rounds, unlikely sequences for marital status across the round-specific variables do exist.

The person identifier for each individual’s spouse is reported in SPOUID31, SPOUID42, SPOUID53, and SPOUID14. These are the PIDs (within each family) of the person identified as the spouse during Round 3/1, Round 4/2, and Round 5/3 and as of December 31, 2014, respectively. If no spouse was identified in the household, the variable was coded as 995 “No Spouse in House”. Those with unknown marital status are coded as 996 “Marital Status Unknown”. Persons under the age of 16 are coded as 997 “Less than 16 Years Old”.

The SPOUIN31, SPOUIN42, SPOUIN53, and SPOUIN14 variables indicate whether a person’s spouse was present in the RU during Round 3/1, Round 4/2, Round 5/3 and as of December 31, 2014 respectively. If the person had no spouse in the household, the value was coded as 2 “Not Married/No Spouse”. For persons under the age of 16 the value was coded as 3 “Under 16 – Inapplicable”.

The SPOUID and SPOUIN variables were obtained from RE76A, where the respondent was asked to identify how each pair of persons in the household was related. Analysts should note that this information was collected in a set of questions separate from the questions that asked about marital status. While editing was performed to ensure that SPOUID and SPOUIN are consistent within each round, there was no consistency check between these variables and marital status in a given round. Apparent discrepancies between marital status and spouse information may be due to any of the following causes:

Ambiguity as to when during a round a change in marital status occurred. This is a result of relationship information being asked for all persons living in the household at any time during the round, while marital status is asked as of the interview date (e.g., If one spouse died during the reference period, the surviving spouse’s marital status would be “Widowed in Round”, but SPOUIN and SPOUID for the same round would indicate that a spouse was present).
Valid discrepancies in the case of persons who are married but not living with their spouse, or separating but still living together.
Discrepancies that cannot be explained for either of the previous reasons.

Student Status and Educational Attainment

The variables FTSTU31X, FTSTU42X, FTSTU53X, and FTSTU14X indicate whether the person was a full-time student at the interview date (or 12/31/14 for FTSTU14X). These variables have valid values for all persons between the ages of 17 - 23 inclusive. When this question was asked during Round 1 of Panel 19, it was based on age as of the 2013 NHIS interview date.

Education questions were only asked when persons first entered MEPS, typically Round 1 for most people. It should be noted that education questions were changed with data collection in 2012 and then changed back to the original questions with data collection in 2015. As a result, the education variables available in this PUF differ based on the Panel and Round when a person first entered MEPS.

EDUCYR and HIDEG were obtained for Panel 18 individuals who had entered MEPS in Panel 18, Round 5 and for Panel 19 individuals who had entered MEPS in Panel 19 Round 3. For confidentiality reasons HIDEG is not provided for this FY 2014 file.

EDUYRDG was obtained for Panel 18 individuals who entered MEPS in Panel 18 Rounds 1-4 and for Panel 19 individuals who entered MEPS in Panel 19, Rounds 1-2.

To relate or recode EDUCYR and HIDEG with EDUYRDG, a fourth variable was created, EDRECODE (Education Recode). Each person will have a value (other than -1) for either the original variables (EDUCYR and HIDEG (not on the file due to confidentiality reasons)) or for the variable (EDUYRDG) but not both. All individuals will have a value for EDRECODE.

EDUCYR contains the number of years of education completed when entering MEPS for individuals 5 years or older. Children under the age of 5 years were coded as -1 “Inapplicable” regardless of whether they attended school. Individuals who were 5 years of age or older and had never attended school were coded as 0. The user should note that EDUCYR is an unedited variable and minimal data cleaning was performed on this variable.

HIDEG (not included in FY 2014 for confidentiality reasons) indicates the highest degree of education attained at the time the individual entered MEPS. Information was obtained from three questions: highest grade completed, high school diploma, and highest degree. Persons under 16 years of age when they first entered MEPS were coded as 8 “Under 16 – Inapplicable”. In cases where the response to the highest degree question was “No Degree” and the response to the highest grade question was 13 through 17, the variable HIDEG was coded as 3 “High School Diploma”. If the response to the highest grade completed was “Refused” or “Don’t Know” and the response to the highest degree question was “No Degree”, the variable HIDEG was coded as 1 “No Degree”. The user should note that HIDEG is an unedited variable and minimal data cleaning was performed on this variable.

EDUYRDG contains information on years of education or highest degree attained when individuals first entered MEPS. Categories for EDUYRDG include: less than or equal to 8th grade; 9-12 grade, no high school diploma; GED or equivalent; high school diploma; some college, no degree; technical associate degree; academic associate degree; bachelor’s degree; master’s, professional school, doctorate degree; and less than 5 years old. The user should note that EDUYRDG is an unedited variable and minimal data cleaning was performed on this variable.

EDRECODE represents a broader classification of education, combining the old and new education question designs. EDRECODE is a discrete variable and has collapsed categories: 1 “less than or equal to 8th grade”; 2 “9th-12th grade with no high school degree or GED”; 13 “GED or high school degree”; 14 “beyond high school, associate’s degree, or college without a 4 year degree”; 15 “4-year college degree, bachelor’s degree”; 16 “master’s, doctorate, or professional degree”. Children under the age of 5 years when they entered MEPS were coded as -1 “Inapplicable”. Note that the EDRECODE variable in the 2012 Full–Year file had more detailed categories than the EDRECODE categories used in the 2014 Full-Year file. When analyzing EDRECODE over time users are advised to check the 2012 and 2014 documentation in order to create a consistent measure.

EDRECODE was edited using EDUYRDG and corresponding NHIS education data for a small number of individuals in Panel 18 (460 persons) and in Panel 19 (327 persons.) The EDRECODE values of these persons were edited to the EDRECODE category 13 ‘GED OR HS GRAD’ based on NHIS data and apply to some of the individuals who had EDUYRDG categories of ‘11TH GRADE’ or ‘12TH GRADE, NO HS DIPLOMA OR GED.’ This edit was designed to improve consistency between the education data from the old and the new education questions that are blended into the EDRECODE variable.

Military Service and Honorable Discharge

Information on active duty military status was collected during each round of the MEPS interview. Persons currently on full-time active duty status are identified in the variables ACTDTY31, ACTDTY42, and ACTDTY53. Those under 16 years of age were coded as 3 “Under 16 – Inapplicable”, and those over the age of 59 were coded as 4 “Over 59 – Inapplicable”.

Persons who have been honorably discharged from active duty in the Armed Forces are identified by HONRDC31, HONRDC42, and HONRDC53. Those 16 years of age and under are coded as 3 “16 or Younger – Inapplicable”, and those over 16 and currently serving on full-time active duty in the military are coded as 4 “Now Active Duty”.

Relationship to the Reference Person within Reporting Units

For each Reporting Unit (RU), the person who owns or rents the DU is usually defined as the reference person. For student RUs, the student is defined as the reference person. (For additional information on reference persons, see the documentation on survey administration variables.) The relationship variables indicate the relationship of each individual to the reference person of the Reporting Unit (RU) in a given round. Prior to FY 2013, these variables, RFREL31X, RFREL42X, RFREL53X, and RFREL13X, were provided with detailed relationships. Beginning FY 2013, for confidentiality, the detailed relationships were combined into more general categories in the new variables REFRL31X, REFRL42X, REFRL53X, and REFRL13X (REFRL14X in FY 2014). For the reference person, these variables have the value “Household reference person”; for all other persons in the RU, relationship to the reference person is indicated by codes representing “Spouse”, “Unmarried Partner”, “Child”, etc. A code of 91, meaning “Other Related, Specify”, was used to indicate rarely observed relationship descriptions such as “Mother of Partner”, “Partner of Sister”, etc. If the relationship of an individual to the reference person was not ascertained during the round-specific interview, relationships between other RU members were used, where possible, to assign a relationship to the reference person. If MEPS data from calendar year 2014 were not sufficient to identify the relationship of an individual to the reference person, relationship variables from the 2013 MEPS or NHIS data were used to assign a relationship. In the event that a meaningful value could not be determined or data were missing, the relationship variable was assigned a missing value code.

If the relationship of two individuals indicated they were spouses, but both had marital status indicating they were not married, their relationship was changed to non-marital partners. In addition, the relationship variables were edited to insure that they did not change across rounds for RUs in which the reference person did not change, with the exception of relationships identified as partner, spouse, or foster relationships.

Parent Identifiers

The variables MOPID31X, MOPID42X, MOPID53X and DAPID31X, DAPID42X DAPID53X are round-specific and are used to identify the parents (biological, adopted, or step) of the person represented on that record. MOPID##X contains the person identifier (PID) for each individual’s mother if she lived in the RU in that panel/round of the survey, or a value of –1 “Inapplicable” if she did not. Similarly, DAPID##X contains the person identifier (PID) for each individual’s father if he lived in the RU in that panel/round of the survey, or a value of –1 “Inapplicable” if he did not. MOPID##X and DAPID##X were constructed based on information collected in the relationship grid of the instrument each round at question RE76A, and include biological, adopted, and stepparents. Foster parents were not included. For persons who were not present in the household during a round, MOPID##X and DAPID##X have values of –1 “Inapplicable”.

Edits were performed to ensure that MOPID##X and DAPID##X were consistent with each individual’s age, sex, and other relationships within the family. For instance, the gender of the parent must be consistent with the indicated relationship; mothers are at least 12 years older than the person and no more than 55 years older than the person; fathers are at least 12 years older than the person; each person has no more than one mother and no more than one father; any values set for MOPID##X and DAPID##X were removed from any person identified as a foster child; and the PID for the person’s mother and father are valid PIDs for that person’s RU for the 2014 Full Year File.

2.5.4 Income and Tax Filing Variables (AFDC14-HIEUIDX)

The file provides income and tax-related variables that were constructed primarily from data collected in the Panel 18 Round 5 and Panel 19 Round 3 Income Sections. Person-level income amounts have been edited and imputed for every record on the full-year file, with detailed imputation flags provided as a guide to the method of editing. The tax-filing variables and some program participation variables are unedited, as discussed below.

During imputation, logical editing and weighted, sequential hot-decks were used to estimate income amounts for missing values (both for item nonresponse and for persons in the full-year file who were not in the income rounds). Reported income components were generally left unedited (with the few exceptions noted below). Thus, analysts using these data may wish to apply additional checks for outlier values that would appear to stem from misreporting.

The editing process began with wage and salary income, WAGEP14X. Complete responses were left unedited, and this group of people was assigned WAGIMP14=1, where WAGIMP14 is the imputation flag for wage and salary data. The only exception was for a small number of persons who reported zero wage and salary income despite having been employed for pay during the year according to round-level data (see below). Since data on tax filing and on taxable income sources were collected using an approach that encouraged respondents to provide information from their federal tax returns, logical edits were used to assign separate income amounts to married persons whose responses were based on combined income amounts on their joint tax returns.

Persons assigned WAGIMP14=2 were those providing broad income ranges (brackets) rather than giving specific dollar amounts. Weighted sequential hot-decking was used to provide these individuals with specific dollar amounts. For this imputation, donors were persons who reported specific dollar amounts within the corresponding broad income ranges. In 2014 (as in all previous years) there were a small number of cases where WAGEPX14=0 and WAGIMP14=2. These are cases where a married couple filing jointly reported wages with a bracket, and reported that one spouse earned 0% of that bracketed amount. All WAGEP14X hot-deck imputations used cells defined on the basis of a conventional list of person-level characteristics including age, education, employment status, race, sex, and region.

Persons assigned WAGIMP14=3 were those who did not report wage and salary income and who were assigned WAGEP14X=0 based on not having been employed during the year.

Persons assigned WAGIMP14=4 were those who did not provide valid dollar amounts or dollar ranges, but for whom we had related information from the employment sections of the survey. In most cases this information included wages, hours, and weeks worked; for some persons, only hours and weeks worked data were reported in the employment section. The available employment section data were used to construct annualized wage amounts to be used in place of missing income section annual wage and salary data. Comparisons of reported and constructed wages and salaries using persons who provided both sorts of information yielded a high degree of confidence that employment data could be reliably used to derive values to serve in place of missing wage and salary information. To implement this approach, part-year responders were assumed to be fully employed during the remainder of the year if they were employed during the period in which they provided data. An exception was made for those who either died or were institutionalized. These persons were assigned zero wages and salaries for the time they were not in MEPS.

Hot-deck imputation was used for the remaining persons with missing WAGEP14X. Donor pools included persons whose WAGEP14X amounts were edited in the steps described above. Whenever possible, the hot-deck imputations used data on whether or not the person had been employed at any point during the year (and, if available, the number of weeks worked). Imputations for persons deemed to have been employed were conditional in nature, using only donors with positive WAGEP14X amounts (WAGIMP14=5). Imputations for WAGEP14X for the remaining persons were unconditional, using both workers and non-workers as donors (WAGIMP14=6).

After editing WAGEP14X for all persons in the full-year file, the remaining income sources were edited in the following sequence: INTRP14X, BUSNP14X, DIVDP14X, ALIMP14X, SALEP14X, TRSTP14X, PENSP14X, IRASP14X, SSECP14X, UNEMP14X, WCMPP14X, VETSP14X, CASHP14X, OTHRP14X, CHLDP14X, SSIP14X, and PUBP14X. Income components were edited sequentially, in each case using information regarding income amounts that had already been edited (so as to maintain patterns of correlation across income sources whenever possible). In all cases, bracketed responses were edited first (using hot-deck imputations from donors in corresponding brackets who gave specific dollar amounts), followed by imputations for remaining missing values. The hot-deck imputations used cells defined on the basis of income amounts already edited and a conventional list of person-level characteristics such as age, education, employment status, race, sex, and region. In addition, hot-deck imputations for CHLDP14X used family-level information concerning marital status and the number of children. Hot-deck imputations for SSIP14X and PUBP14X were also assigned using, in part, simulated program eligibility indicators that integrated state-level program eligibility criteria with data on family composition and income.

In the hot-decks for some income types, information from the National Health Interview Survey (NHIS) was used. The NHIS sample is the frame for the new sample selected for MEPS collection each year, with a year’s time lag. Data from the 2012 NHIS correspond to MEPS Panel 18, while those from the 2013 NHIS correspond to MEPS Panel 19. Because MEPS units come from the NHIS, it is possible to match individual MEPS responding units to an NHIS unit.

Taking advantage of this matching ability, income recipiency indicators collected by NHIS were used in imputing for missing data in certain MEPS income components - interest, dividends, business income, pensions, and Social Security. (Not all MEPS income categories have an equivalent in NHIS. Also, wage data were available from NHIS, but were not used in the MEPS imputation process.)

In cases where data on a particular income category were missing for a person in MEPS, the indicator in that income category on the NHIS file was employed, if a valid response was supplied. Indicators were examined for the entire tax-filing unit (two people in the case of married couples filing jointly; one person in all other cases).

Reported income amounts of less than one dollar were treated as missing amounts (to be hot-decked from donors with positive amounts of the corresponding income source). Also, very few cases of outlier responses were edited (primarily public sources of income that exceeded possible amounts). Otherwise, reported amounts were left unchanged.

For each income component, the corresponding xxxxIMP14 variable contains an indicator concerning the method for editing/imputation. All the flag variables have the following formatted values:

1 = Original response used;
2 = Bracket converted;
3 = Missing value set to 0;
4 = Weeks worked/earnings used (WAGIMP14 only);
5 = Conditional hot-deck;
6 = Unconditional hot-deck;

Missing values were set to zero when there were too few recipients to warrant hot-deck imputations of positive values (as in the case of ALIMP14X received by males). “Conditional hot-decks” indicate instances where the respondent indicated receipt but not a specific dollar amount. In these cases, the donor pool was restricted to persons with nonzero amounts of the income source in question. “Unconditional hot-decks” indicate instances where the donor pool included persons receiving both zero and nonzero amounts (implemented in cases where there was little or no information about a person’s income source).

Total person-level income (TTLP14X) is the sum of all income components with the exception of SALEP14X (to match as closely as possible the CPS definition of income; see Section 2.5.4.2). Some researchers may wish to define their own income measure by adding in one or both of these excluded components.

The tax variables, food stamp variables, and welfare participation flag are all completely unedited. Note that while the welfare participation flag is named AFDC14, in fact this variable reflects participation in Temporary Assistance for Needy Families (TANF), with respondents having been prompted with “TANF”, “AFDC”, and “welfare.” Unedited tax variables are provided to assist researchers building tax simulation programs. No efforts have been made to eliminate inconsistencies among these program participation and tax variables and other MEPS data. All of these unedited variables should be used with great care.

2.5.4.1 Income Top-Coding

All person-level income amounts on the file, including both total income and the separate sources of income, were top-coded to preserve confidentiality. For each income source, top codes were applied to the top percentile of all cases (including negative amounts that exceeded income thresholds in absolute value). In cases where less than one percent of all persons received a particular income source, all recipients were top-coded.

Top-coded income amounts were masked using a regression-based approach. The regressions relied on many of the same variables used in the hot-deck imputations, with the dependent variable in each case being the natural logarithm of the amount that the income component was in excess of its top-code threshold. Predicted values from this regression were reconverted from logarithms to levels using a smearing correction, and these predicted amounts were then added back to the top-code thresholds. This approach preserves the component-by-component weighted means (both overall and among top-coded cases), while also preserving much of the income distribution conditional on the variables contained in the regressions. At the same time, this approach ensures that every reported amount in excess of its respective threshold is altered on the public use file. The process of top-coding income amounts in this way inevitably introduces measurement error in cases where income amounts were reported correctly by respondents. Note, however, that top-coding can also help to reduce the impact of outliers that occur due to reporting errors.

Total person-level income is constructed as the sum of the adjusted person-level income components. Having constructed total income in this manner, this total was then top-coded using the same regression-based procedure described above (again masking the top percentile of cases). Finally, the components of income were scaled up or down in order to make the sources of income consistent with the newly-adjusted totals.

2.5.4.2 Poverty Status

The definitions of income, family, and poverty categories used to construct the related variables in this file were taken from the 2014 poverty statistics developed by the Current Population Survey (CPS). The categorical variable for 2014 family income as a percentage of poverty (POVCAT14) was constructed using the same method as in earlier years’ files.

FAMINC14 contains total family income for each person’s CPS family. Family income was derived by constructing person-level total income comprising annual earnings from wages, salaries, bonuses, tips, commissions; business and farm gains and losses; unemployment and workers’ compensation; interest and dividends; alimony, child support, and other private cash transfers; private pensions, IRA withdrawals, social security, and veterans payments; supplemental security income and cash welfare payments from public assistance, Temporary Assistance for Needy Families, and related programs; gains or losses from estates, trusts, partnerships, S corporations, rent, and royalties; and a small amount of “other” income. Person-level income excluded tax refunds and capital gains. Person-level income totals were then summed over family members, as defined by CPSFAMID, to yield CPS family-level total income (FAMINC14).

POVLEV14 is the continuous version of the POVCAT14 variable. The POVLEV14 percentage was computed by dividing CPS family income by the applicable poverty line (based on family size and composition). POVCAT14 takes the POVLEV14 percentage for each person and classifies it into one of five poverty categories: negative or poor (less than 100%), near poor (100% to less than 125%), low income (125% to less than 200%), middle income (200% to less than 400%), and high income (greater than or equal to 400%). Persons missing CPSFAMID were treated as one-person families in constructing their poverty percentage and category.

Family income, as well as the components of person-level income, has been subjected to internal editing patterns and derivation methods that are in accordance to specific definitions, and are not being released at this time. Researchers working with a family definition other than CPSFAMID may wish to create their own versions of total family income.

Health Insurance Eligibility Units (HIEUs) are sub-family relationship units constructed to include adults plus those family members who would typically be eligible for coverage under the adults' private health insurance family plans. To construct the HIEUIDX variable, which links persons into a common HIEU, we begin with the family identification variable CPSFAMID. Working with this family ID, we define HIEUIDX using family relationships as of the end of 2013. Persons missing end-of-year relationship information are assigned to an HIEUIDX using relationship information from the last round in which they provided such information. HIEUs comprise adults, their spouses, and their unmarried natural/adoptive children age 18 and under. We also include children under age 24 who are full-time students (living at home or away from home). Other children who do not live with their natural/adoptive adult parents are placed in an HIEUIDX as follows:

Foster children always comprise a separate HIEUIDX.
Other unmarried children are placed in stepparent HIEUIDX, grandparent HIEUIDX, great-grandparent HIEUIDX, or aunt/uncle HIEUIDX.
Children of unmarried minors are placed (along with their minor parents) in the HIEUIDX of their adult grandparents (if possible). Married minors are placed into separate HIEUs along with any spouses and children they might have.
Some HIEUs are headed by unmarried minors, when there is no adult family member present in the CPSFAMID.

HIEUs do not, in general, comprise adult (nonmarital) partnerships, because unmarried adult partners are rarely eligible for dependent coverage under each other's insurance. The exception to this rule is that we include adult partners in the same HIEU if there is at least one (out-of-wedlock) child in the family that links to both adult partners. In cases of missing or contradictory relationship codes, HIEUs are edited by hand, with the presumption being that the adults and children form a nuclear family.

2.5.5 Person-Level Condition Variables (RTHLTH31-ADHDAGED)

2.5.5.1 Perceived Health Status and Pregnancy Indicator

Perceived health status (RTHLTH31, RTHLTH42, and RTHLTH53) and perceived mental health status (MNHLTH31, MNHLTH42, and MNHLTH53) were collected in the Priority Conditions Enumeration (PE) section. The target persons of the questions are all current or institutionalized persons regardless of age. These questions (PE00A and PE00B) asked the respondent to rate each person in the family according to the following categories: excellent, very good, good, fair, and poor.

Respondents were asked if anyone had been pregnant during the round (“Since (start date) has anyone in the family been pregnant at any time?”). If it was reported that someone had been pregnant, questions about pregnancy were asked about female persons aged 15 through 55. Males, and females who were younger than 16 or older than 44 (for confidentiality purposes), were coded as “Inapplicable” (-1). PREGNT31 indicates if the person was pregnant in Round 3 of Panel 18 or Round 1 of Panel 19, PREGNT42 indicates if the person was pregnant in Round 4 of Panel 18 or Round 2 of Panel 19, and PREGNT53 indicates whether the person was pregnant in Round 5 of Panel 18 or Round 3 of Panel 19.

2.5.5.2 Priority Condition Variables (HIBPDX-ADHDAGED)

The PE section was asked in its entirety in Round 1 for all current or institutionalized persons, and in Rounds 2 and 4 for only new RU members. In Rounds 3 and 5, the specific condition questions (except joint pain and chronic bronchitis) were asked only if the person had not reported the condition in a previous round; the joint pain and chronic bronchitis questions were asked in Rounds 3 and 5 for all current or institutionalized persons aged 18 or older, regardless of Round 1, Round 2, and Round 4 responses.

Priority condition variables whose names end in “DX” indicate whether the person was ever diagnosed with the condition. For chronic bronchitis, joint pain, and some asthma follow-up questions (ASSTIL##, ASATAK##, and ASTHEP## described below), variables ending in “31” reflect data obtained in Round 3 of Panel 18 and Round 1 or 2 of Panel 19 and variables ending in “53” reflect data obtained in Round 4 or 5 of Panel 18 and Round 3 of Panel 19. For asthma treatment variables (ASACUT53 through ASWNFL53), the data were obtained in Round 5 of Panel 18 and Round 3 of Panel 19.

Before 2007, the DX variables contained a “53” suffix because they reflected data collected only in Rounds 3 and 5 in the Priority Conditions Supplement (PC) section. Beginning in 2007, the suffix was removed because the data were collected in all rounds. Diagnoses data (except attention deficit hyperactivity disorder/attention deficit disorder and asthma) were collected for persons over 17 years of age. If edited age is within range for the variable to be set, but the source data are missing because person’s age in CAPI is not within range, the constructed variable is set to “Not Ascertained” (-9). Additionally, if the person was 17 in Round 1, turned 18 in Round 2, and was not a current or institutionalized RU member in Round 3, the source data are missing per design. However, the DX variables are set to “Not Ascertained” (-9) as the person was old enough to be asked the PE questions within the data year. Following the same pattern, attention deficit hyperactivity disorder/attention deficit disorder is asked of persons age 5 to 17 and asthma is asked of persons of all ages. Exceptions to this pattern are the variables JTPAIN31, JTPAIN53, CHBRON31, and CHBRON53 which are described in greater detail below.

Questions were asked regarding the following conditions:

High blood pressure, including multiple diagnoses
Heart disease (including coronary heart disease, angina, myocardial infarction, and other unspecified heart disease)
Stroke
Emphysema
Chronic Bronchitis
High cholesterol, including the age of diagnosis
Cancer
Diabetes
Joint pain
Arthritis
Asthma
Attention Deficit Hyperactivity Disorder/Attention Deficit Disorder (ADHD/ADD)

These conditions were selected because of their relatively high prevalence, and because generally accepted standards for appropriate clinical care have been developed. As part of AHRQ’s focus on the quality of health care, this series of questions obtained information on the receipt of tests or procedures appropriate for each condition. This information thus supplements other information on medical conditions that is gathered in other parts of the interview.

Condition data were collected at the person-by-round level (indicating if the person was ever diagnosed with the condition) and at the condition level. If the person reported having been diagnosed with a condition, the person-by-round variable was set to ‘1’ (Yes) and a condition record for that medical condition was created.

Editing of these variables focused on checking that skip patterns were consistent.

High Blood Pressure

Questions about high blood pressure (hypertension) were asked only of persons aged 18 or older. Consequently, persons aged 17 or younger were coded as “Inapplicable” (-1) on these variables. HIBPDX ascertained whether the person had ever been diagnosed as having high blood pressure (other than during pregnancy). Those who had received this diagnosis were also asked if they had been told on two or more different visits that they had high blood pressure (BPMLDX). The age of diagnosis for high blood pressure (HIBPAGED) is included in this file. This variable is top-coded to 85 years of age.

Heart Disease

Heart disease questions were asked only of persons aged 18 or older. Consequently, persons aged 17 or younger were coded as “Inapplicable” (-1) on all the variables in this set.

CHDDX – asked if the person had ever been diagnosed as having coronary heart disease
ANGIDX – asked if the person had ever been diagnosed as having angina, or angina pectoris
MIDX – asked if the person had ever been diagnosed as having a heart attack, or myocardial infarction
OHRTDX – asked if the person had ever been diagnosed with any other kind of heart disease or condition

The age of diagnosis for coronary heart disease (CHDAGED), angina (ANGIAGED), heart attack or myocardial infarction (MIAGED), and other kind of heart disease (OHRTAGED) are included in this file. These variables are top-coded to 85 years of age.

Stroke

STRKDX asked if the person (aged 18 or older) had ever been diagnosed as having had a stroke or transient ischemic attack (TIA or ministroke). Persons aged 17 or younger were coded as “Inapplicable” (-1). The age of diagnosis for stroke or TIA (STRKAGED) is included in this file. This variable is top-coded to 85 years of age.

Emphysema

EMPHDX asked if the person (aged 18 or older) had ever been diagnosed with emphysema. Persons aged 17 or younger were coded as “Inapplicable” (-1). The age of diagnosis for emphysema (EMPHAGED) is included in this file. This variable is top-coded to 85 years of age.

Chronic Bronchitis

CHBRON31 and CHBRON53 asked if the person (aged 18 or older) has had chronic bronchitis in the last 12 months. Persons aged 17 or younger were coded as “Inapplicable” (-1).

High Cholesterol

Questions about high cholesterol were asked of persons aged 18 or older. Consequently, persons aged 17 or younger were coded as “Inapplicable” (-1) on these variables. CHOLDX ascertained whether the person had ever been diagnosed as having high cholesterol. Through 2007, a person-level variable (CHLAGE) indicated the age of diagnosis for high cholesterol on the Person-Level Use PUF. The age of diagnosis for high cholesterol (CHOLAGED) is included in this file. This variable is top-coded to 85 years of age.

Cancer

Questions about cancer were asked only of persons aged 18 or older. Consequently, persons aged 17 or younger were coded as “Inapplicable” (-1) on these variables. CANCERDX ascertained whether the person had ever been diagnosed as having cancer or a malignancy of any kind. If the person answered “Yes” they were asked at PE22 what type of cancer was diagnosed. CABLADDR, CABLOOD, CABREAST, CACERVIX, CACOLON, CALUNG, CALYMPH, CAMELANO, CAMUSCLE, CAOTHER, CAPROSTA, CASKINNM, CASKINDK, and CAUTERUS indicate selection of cancer of the bladder, blood, breast, cervix, colon, or lung; lymphoma or melanoma; cancer of the soft tissue, muscle, or fat; other type of cancer, cancer of the prostate, skin, or uterus. Cancer of the cervix or uterus could not be reported for males, and cancer of the prostate could not be reported for females.

Beginning with the 2013 Consolidated file, variables indicating the age of diagnosis for each reported cancer and whether each reported cancer was in remission were removed from the file for confidentiality reasons.

Recoding of Cancer Variables

Specific cancer diagnosis variables with a frequency count fewer than 20 and those considered clinically rare (i.e., appear on the National Institutes of Health’s list of rare diseases), were removed from the file for confidentiality reasons, and the corresponding variable CAOTHER, indicating diagnosis of a cancer that is not counted individually, was recoded to Yes (1) as necessary.

In data year 2014, the clinically rare cancers are:

bone
brain
esophagus
gallbladder
kidney
larynx
leukemia
liver
mouth
ovary
pancreas
rectum
stomach
testis
throat
thyroid

The variable CABREAST, which indicates diagnosis of breast cancer, was recoded to “Inapplicable” (-1) for males for confidentiality reasons. The corresponding value of the general cancer diagnosis variable, CANCERDX, was recoded to “Not Ascertained” (-9), and the corresponding values of remaining specific cancer variables were recoded to “Inapplicable” (-1).

Diabetes

DIABDX indicates whether each person (aged 18 or older) had ever been diagnosed with diabetes (excluding gestational diabetes). Persons aged 17 or younger were coded as “Inapplicable” (-1). The age of diagnosis for diabetes (DIABAGED) is included in this file. This variable is top-coded to 85 years of age.

REFDIAB allows the respondent to indicate that diabetes was reported in the PE section in error (REFDIAB = 2). Respondents were not prompted to confirm or deny the report of diabetes; REFDIAB was set to “2” (Person Does Not Have Diabetes) only if the respondent offered the information, and DIABDX is set to “No” (2).

Each person said to have received a diagnosis of diabetes was asked to complete a special self-administered questionnaire. The documentation for this questionnaire appears in the Diabetes Care Survey (DCS) section of the documentation.

Joint Pain

JTPAIN31 and JTPAIN53 asked if the person (aged 18 or older) had experienced pain, swelling, or stiffness around a joint in the last 12 months. This question is not intended to be used as an indicator of a diagnosis of arthritis. Persons aged 17 or younger were coded as “Inapplicable”
(-1).

Arthritis

ARTHDX asked if the person (aged 18 or older) had ever been diagnosed with arthritis. Persons aged 17 or younger were coded as “Inapplicable” (-1). Those who said “Yes” were asked a follow up question to determine the type of arthritis. ARTHTYPE indicates if the diagnosis was for Rheumatoid Arthritis (1), Osteoarthritis (2), or non-specific arthritis (3). The age of diagnosis for arthritis (ARTHAGED) is included in this file and may be recoded in some cases to “Not Ascertained” (-9) for confidentiality reasons. This variable is top-coded to 85 years of age.

Asthma

ASTHDX indicates whether a person had ever been diagnosed with asthma. The age of diagnosis for asthma (ASTHAGED) is included in this file. This variable is top-coded to 85 years of age.

Those who said “Yes” to asthma diagnosis were asked additional questions. ASSTIL31 and ASSTIL53 asked if the person still had asthma. ASATAK31 and ASATAK53 asked whether the person had experienced an episode of asthma or an asthma attack in the past 12 months. If the person did not experience an asthma attack in the past 12 months, a follow-up question (ASTHEPIS31, ASTHEPIS53) asked when the last asthma episode or asthma attack occurred.

Additional follow-up questions regarding asthma medication used for quick relief (ASACUT53), preventive medicine (ASPREV53), and peak flow meters (ASPKFL53) were asked. These questions were asked if the person reported having been diagnosed with asthma (ASTHDX = 1). ASACUT53 asked whether the person had used the kind of prescription inhaler that you breathe in through your mouth that gives quick relief from asthma symptoms. ASPREV53 asked whether the person had ever taken the preventive kind of asthma medicine used every day to protect the lungs and prevent attacks, including both oral medicine and inhalers. ASPKFL53 indicates whether the person with asthma had a peak flow meter at home.

Persons who said “Yes” to ASACUT53 were asked whether they had used more than three canisters of this type of inhaler in the past 3 months (ASMRCN53). Persons who said “Yes” to ASPREV53 were asked whether they now took this kind of medication daily or almost daily (ASDALY53). Persons who said “Yes” to ASPKFL53 were asked if they ever used the peak flow meter (ASEVFL53). Those persons who said “Yes” to ASEVFL53 were asked when they last used the peak flow meter (ASWNFL53).

Because the asthma diagnosis variable reflects three rounds of data in Panel 19, it may appear that there are discrepancies between the diagnosis variable and the follow-up variables. If a person reported asthma in the PE section in Round 3, ASATAK31 and ASSTIL31 will be set to “Inapplicable” (-1) as the person had not reported asthma in Round 1 or 2. If a person reported asthma in the PE section in Round 1 or 2 but was not a current RU member in Round 3, the 53 asthma variables will be set to “Inapplicable” (-1) as the Round 3 follow-up data were not collected for the person.

Attention Deficit Hyperactivity Disorder/Attention Deficit Disorder

ADHDADDX asked if persons aged 5 through 17 had ever been diagnosed as having Attention Deficit Hyperactivity Disorder or Attention Deficit Disorder. Persons younger than 5 or older than 17 were coded as “Inapplicable” (-1). The age of diagnosis for attention deficit hyperactivity disorder/attention deficit disorder (ADHDAGED) is included in this file.

2.5.6 Health Status Variables (IADLHP31-DSPRX53)

Due to the overlapping panel design of the MEPS (Round 3 for Panel 18 overlapped with Round 1 for Panel 19, Round 4 for Panel 18 coincided with Round 2 for Panel 19, and Round 5 for Panel 18 occurred at the same time as Round 3 for Panel 19), data from overlapping rounds have been combined across panels. Thus, any variable ending in “31” reflects data obtained in Round 3 of Panel 18 and Round 1 of Panel 19. Analogous comments apply to variables ending in “42” and “53”. Health Status variables whose names end in “14” indicate a full-year measurement.

This data release incorporates information from calendar year 2014. However, health status data obtained in Round 3 of both Panel 18 and Panel 19 are included in variables that have names ending in “31” and “53” respectively. For persons in Panel 18, Round 3 extended from 2013 into 2014. Therefore, for these people, some information from late 2013 is included for variables that have names ending in “31”. For persons in Panel 19, Round 3 extended from 2014 into 2015. Therefore, for these people, some information from early 2015 is included for variables that have names ending in “53”. Note that for most Panel 18 persons, the Round 5 reference period ends on December 31, 2014; however, the Round 5 interview actually occurs in 2015. Round 5 respondents receive an instruction at the start of the Health Status (HE) section of CAPI to limit information about health status and limitations to the period ending on December 31, 2014. Nevertheless, if respondents forget or ignore this reference period instruction, some information collected in this section in Round 5 (variables ending in “53”) might reflect circumstances in early 2015. Further, health status questions asked in the Preventive Care (AP) section of CAPI in Round 5 do not contain a similar explicit instruction that the reference period ends on December 31, 2014, although this is stated at the start of the overall interview. Hence, in these sections, respondents may also be providing health status information that pertains to 2015.

Health Status variables in this data release can be classified into several conceptually distinct sets:

IADL (Instrumental Activities of Daily Living) and ADL (Activities of Daily Living) limitations
Functional and activity limitations
Hearing, vision problems
Disability status
Hearing aids, eyeglasses
Any limitations
Child health and preventive care
Preventive care
Self-administered questionnaire
Diabetes care survey

In general, Health Status variables involved the construction of person-level variables based on information collected in the Health Status section of the questionnaire. Many Health Status questions were initially asked at the family level to ascertain if anyone in the household had a particular problem or limitation. These were followed up with questions to determine which household member had each problem or limitation. All information ascertained at the family level has been brought to the person level for this file. Logical edits were performed in constructing the person-level variables to assure that family-level and person-level values were consistent. Particular attention was given to cases where missing values were reported at the family level to ensure that appropriate information was carried to the person level.

Inapplicable cases occurred when a question was never asked because of a skip pattern in the survey (e.g., individuals who were 13 years of age or older were not asked some follow-up verification questions; individuals older than 17 were not asked questions pertaining to children’s health status). Inapplicable cases are coded as -1. In addition, deceased persons were coded as “Inapplicable” (-1).

Each of the sets of variables listed above will be described in turn.

2.5.6.1 IADL and ADL Limitations

IADL Help

The Instrumental Activities of Daily Living (IADL) Help or Supervision variables (IADLHP31 and IADLHP53) were each constructed from a series of three questions administered in the Health Status section of the interview in Panel 18 Rounds 3 and 5 and Panel 19 Rounds 1 and 3. The initial question (HE01) determined if anyone in the family received help or supervision with IADLs such as using the telephone, paying bills, taking medications, preparing light meals, doing laundry, or going shopping. If the response was “Yes”, a follow-up question (HE02) was asked to determine which household member(s) received this help or supervision. For persons under age 13, a final verification question (HE03) was asked to confirm that the IADL help or supervision was the result of an impairment or physical or mental health problem. If the response to the final verification question was “No”, IADLHP31 and IADLHP53 were coded “No” for persons under the age of 13.

If no one in the family was identified as receiving help or supervision with IADLs, all members of the family were coded as receiving no IADL help or supervision. In cases where the response to the family-level question was “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), all persons were coded according to the family-level response. In cases where the response to the family-level question (HE01) was “Yes” but no specific individuals were identified in the follow-up question as having IADL difficulties, all persons were coded as “Don’t Know” (-8).

In FY 2013, the Panel 17 Round 4/Panel 18 Round 2 IADL questions were dropped from the interview, so IADLHP42 is no longer constructed.

Through 2013, the Duration of IADL Condition variable (IADL3M31) was constructed from a follow-up question (HE03A) in the Health Status section of the interview. HE03A was dropped from the interview in Panel 17 Round 4/Panel 18 Round 2. Panel 17 Round 3 and Panel 18 Round 1 were the last panels and rounds for which the Duration of IADL Condition variable was constructed.

ADL Help

The Activities of Daily Living (ADL) Help or Supervision variables (ADLHLP31 and ADLHLP53) were each constructed in the same manner, and for the same persons, as the IADL help variables, but using questions HE04-HE06 in Panel 18 Rounds 3 and 5 and Panel 19 Rounds 1 and 3. Coding conventions for missing data were the same as for the IADL variables.

In FY 2013, the Panel 17 Round 4/Panel 18 Round 2 ADL questions were dropped from the interview, so ADLHLP42 is no longer constructed.

Through 2013, the Duration of ADL Condition variable (ADL3MO31) was constructed from a follow-up question (HE06A) in the Health Status section of the interview. HE06A was dropped from the interview in Panel 17 Round 4/Panel 18 Round 2. Panel 17 Round 3 and Panel 18 Round 1 were the last panels and rounds for which the Duration of ADL Condition variable was constructed.

2.5.6.2 Functional and Activity Limitations

Functional Limitations

A series of questions asked in Panel 18 Rounds 3 and 5 and Panel 19 Rounds 1 and 3 pertained to functional limitations, which are defined as difficulty in performing certain specific physical actions. WLKLIM31 and WLKLIM53 were the filter questions, depending on the round. These variables were derived from a question (HE09) that was asked at the family level: “Does anyone in the family have difficulties walking, climbing stairs, grasping objects, reaching overhead, lifting, bending or stooping, or standing for long periods of time?” If the answer was “No”, then all family members were coded as “No” (2) on WLKLIM31 or WLKLIM53. If the answer was “Yes”, then the specific persons who had any of these difficulties were identified and coded as “Yes” (1), and remaining family members were coded as “No” (2). If the response to the family-level question was “Don’t Know” (-8), “Refused” (-7), “Not Ascertained” (-9), or “Inapplicable” (-1), then the corresponding missing value code was applied to each family member’s value for WLKLIM31 or WLKLIM53. If the answer to HE09 was “Yes” (1) but no specific individual was named as experiencing such difficulties, then each family member was assigned “Don’t Know” (-8). Deceased persons were assigned a code of “Inapplicable” (-1) for WLKLIM31 or WLKLIM53.

For Rounds 3 (Panel 18) and 1 (Panel 19), if WLKLIM31 was coded “Yes” (1) for any family member, a subsequent series of questions was administered. The series of questions for which WLKLIM31 served as a filter is as follows:

LFTDIF31 – difficulty lifting 10 pounds
STPDIF31 – difficulty walking up 10 steps
WLKDIF31 – difficulty walking 3 blocks
MILDIF31 – difficulty walking a mile
STNDIF31 – difficulty standing 20 minutes
BENDIF31 – difficulty bending or stooping
RCHDIF31 – difficulty reaching over head
FNGRDF31 – difficulty using fingers to grasp

This series of questions was asked separately for each person whose response to WLKLIM31 was coded “Yes” (1). The series of questions was not asked for other individual family members whose response to WLKLIM31 was “No” (2). In addition, this series was not asked about family members who were less than 13 years of age, regardless of their status on WLKLIM31. These questions were not asked about deceased family members. In such cases (i.e., WLKLIM31 = 2, or age < 13, or PSTATS31 = 23, 24, or 31), each question in the series was coded as “Inapplicable” (-1). Finally, if responses to WLKLIM31 were “Refused” (-7), “Don’t Know”
(-8), “Not Ascertained” (-9), or otherwise “Inapplicable” (-1), then each question in this series was coded as “Inapplicable” (-1).

Analysts should note that WLKLIM31 was asked of all household members, regardless of age. For the subsequent series of questions, however, persons less than 13 years old were skipped and coded as “Inapplicable” (-1). Therefore, it is possible for someone age 12 or younger to have a code of “Yes” (1) on WLKLIM31, and also to have codes of “Inapplicable” on the subsequent series of questions.

Because of a design change in the interview, Panel 17 Round 3 and Panel 18 Round 1 were the last panels and rounds for which WLK3MO31, the follow-up question which determines whether any person with functional limitations was expected to have difficulties with any of these activities for at least three more months, was constructed.

For Rounds 5 (Panel 18) and 3 (Panel 19), the corresponding filter question was WLKLIM53.

The series of questions for which WLKLIM53 served as a filter is as follows:

LFTDIF53 – difficulty lifting 10 pounds
STPDIF53 – difficulty walking up 10 steps
WLKDIF53 – difficulty walking 3 blocks
MILDIF53 – difficulty walking a mile
STNDIF53 – difficulty standing 20 minutes
BENDIF53 – difficulty bending or stooping
RCHDIF53 – difficulty reaching over head
FNGRDF53 – difficulty using fingers to grasp

Editing conventions were the same for this “53” series of variables as they were for the corresponding “31” series described above.

Beginning with Panel 17 Round 4/Panel 18 Round 2, WLK3MO53, the follow-up question which determined whether any person with functional limitations was expected to have difficulties with any of these activities for at least three more months, was dropped from the interview.

Use of Assistive Technology and Social/Recreational Limitations

The variables indicating use of assistive technology (AIDHLP31 and AIDHLP53, from question HE07) and social/recreational limitations (SOCLIM31 and SOCLIM53, from question HE22) were collected initially at the family level. If there was a “Yes” (1) response to the family-level question, a second question identified the specific individual(s) to whom the “Yes” response pertained. Each individual identified as having the difficulty was coded “Yes” (1) for the appropriate variable; all remaining family members were coded “No” (2). If the family-level response was “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” but no specific individual was identified as having difficulty, all family members were coded as “Don’t Know” (-8).

Work, Housework, and School Limitations

The variables indicating any limitation in work, housework, or school (ACTLIM31 and ACTLIM53) were constructed using questions HE19-HE20. Specifically, information was collected initially at the family level. If there was a “Yes” (1) response to the family-level question (HE19), a second question (HE20) identified the specific individual(s) to whom the “Yes” (1) response pertained. Each individual identified as having a limitation was coded “Yes” (1) for the appropriate variable; all remaining family members were coded “No” (2). If the family-level response was “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having difficulty, all family members were coded as “Don’t Know” (-8). Persons less than five years old were coded as “Inapplicable” (-1) on ACTLIM31 and ACTLIM53.

For Round 3 (Panel 18) or Round 1 (Panel 19), if ACTLIM31 was “Yes” (1) and the person was 5 years of age or older, a follow-up question (HE20A) was asked to identify the specific limitation or limitations for each person. These included working at a job (WRKLIM31), doing housework (HSELIM31), or going to school (SCHLIM31). Respondents could answer “Yes” (1) or “No” (2) to each activity; thus a person could report limitations in multiple activities. WRKLIM31, HSELIM31, and SCHLIM31 have values of “Yes” (1) or “No” (2) only if ACTLIM31 was “Yes” (1); each variable was coded as “Inapplicable” (-1) if ACTLIM31 was “No” (2). When ACTLIM31 was “Refused” (-7), these variables were all coded as “Refused”
(-7); when ACTLIM31 was “Don’t Know” (-8), these variables were all coded as “Don’t Know” (-8); and when ACTLIM31 was “Not Ascertained” (-9), these variables were all coded as “Not Ascertained” (-9). If a person was under 5 years old or was deceased, WRKLIM31, HSELIM31, and SCHLIM31 were each coded as “Inapplicable” (-1).

An additional question (UNABLE31) asked if the person was completely unable to work at a job, do housework, or go to school. Those persons who were coded “No” (2), “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9) on ACTLIM31, were under 5 years of age, or were deceased were coded as “Inapplicable” (-1) on UNABLE31. UNABLE31 was asked once for whichever set of WRKLIM31, HSELIM31, and SCHLIM31 the person had limitations; if a person was limited in more than one of these three activities, UNABLE31 did not specify if the person was completely unable to perform all of them, or only some of them.

For Rounds 5 (Panel 18) or 3 (Panel 19) corresponding variables were ACTLIM53, WRKLIM53, HSELIM53, SCHLIM53, and UNABLE53. Editing conventions were the same as those described above.

Cognitive Limitations

The variables indicating any cognitive limitation (COGLIM31 or COGLIM53, depending on the round) were collected at the family level as a three-part question (HE24-01 to HE24-03), asking if any of the adults in the family (1) experience confusion or memory loss, (2) have problems making decisions, or (3) require supervision for their own safety. If a “Yes” response was obtained to any item, the persons affected were identified in HE25, and COGLIM31 or COGLIM53 was coded as “Yes” (1). Remaining family members not identified were coded as “No” (2) for COGLIM31 or COGLIM53.

If responses to HE24-01 through HE24-03 were all “No”, or if two of three were “No” (2) and the remaining was “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), all family members were coded as “No” (2). If responses to the three questions were combinations of “Don’t Know” (-8), “Refused” (-7), and missing, all persons were coded as “Don’t Know” (-8). If the response to any of the three questions was “Yes” (1) but no individual was identified in HE25, all persons were coded as “Don’t Know” (-8).

The cognitive limitations variables (COGLIM31 and COGLIM53) reflect whether any of the three component questions is “Yes” (1). Family members with one, two, or three specific cognitive limitations cannot be distinguished. In addition, because the question asked specifically about adult family members, all persons less than 18 years of age are coded as “Inapplicable”
(-1) on this question.

2.5.6.3 Hearing, Vision Problems

A series of questions (HE26 to HE32), asked in Panel 18 Round 4 and Panel 19 Round 2, provides information on hearing and visual impairment. Household members less than one year old and deceased RU members were coded as “Inapplicable” (-1).

The previous hearing impairment questions were dropped from the interview in FY 2013 and new hearing impairment questions were added at HE26 through HE28. The variables HEARDI42 (ANY DIFFCLTY HEARING W/HEARING AID-RD4/2), HEARMO42 (CAN HEAR MOST CONVERSATION - RD 4/2), HEARSM42 (CAN HEAR SOME CONVERSATION - RD 4/2), and HEARNG42 (HEARING IMPAIRMENT (SUMMARY) - RD 4/2) are no longer constructed.

The new hearing impairment variable, DFHEAR42, indicates whether a person has serious difficulty hearing. This variable was based on two questions, HE26 and HE27. The initial question (HE26) determined if anyone in the family had difficulty hearing. If the response was “Yes” (1), a follow-up question (HE27) was asked to determine which household member(s) had a hearing impairment. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having serious difficulty hearing, all family members were coded as “Don’t Know” (-8).

One subsequent question was asked only about individuals who had difficulty hearing (i.e., DFHEAR42 was “Yes” (1)). DEAF42 indicates whether the family member with hearing impairment is deaf. Persons with no hearing impairment were coded as “Inapplicable” (-1) for this question, as were persons with “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9) responses to DFHEAR42. Prior to FY 2013, HEARDI42 served as the gate question for DEAF42.

The previous visual impairment questions were dropped from the interview in FY 2013 and new visual impairment questions were added at HE29 through HE31. The variables SEEDIF42 (DIFFCLTY SEEING W/GLASSES/CNTCTS-RD 4/2), READNW42 (CAN READ NEWSPRNT W/GLASSES/CNTCTS-RD4/2), RECPEP42 (CAN RECGNZE PEOPLE W/GLASSES/CNTCTS-R4/2), and VISION42 (VISION IMPAIRMENT (SUMMARY) - RD 4/2) are no longer constructed.

The new visual impairment variable, DFSEE42, indicates whether a person has serious difficulty seeing. This variable was based on two questions, HE29 and HE30. The initial question (HE29) determined if anyone in the family had difficulty seeing. If the response was “Yes” (1), a follow-up question (HE30) was asked to determine which household member(s) had a seeing impairment. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having serious difficulty seeing, all family members were coded as “Don’t Know” (-8).

One subsequent question was asked only of individuals who had difficulty seeing (i.e., DFSEE42 was “Yes” (1)). BLIND42 indicates whether the family member with seeing impairment is blind. Persons with no seeing impairment were coded as “Inapplicable” (-1) for this question, as were persons with “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9) responses to DFSEE42. Prior to FY 2013, SEEDIF42 served as the gate question for BLIND42.

2.5.6.4 Disability Status

A series of questions (HE32 to HE39) in Panel 18 Round 4 and Panel 19 Round 2 provides information on cognitive difficulty, difficulty walking or climbing stairs, difficulty dressing or bathing, and difficulty doing errands. Questions regarding cognitive difficulty, difficulty walking or climbing stairs, and difficulty dressing or bathing were asked of household members 5 years of age and older. The question regarding difficulty doing errands was asked of household members 15 years of age and older. Deceased RU members were coded “Inapplicable” (-1).

DFCOG42 indicates whether a person had serious cognitive difficulty. This variable was based on two questions, HE32 and HE33. The initial question (HE32) determined if anyone in the family had difficulty concentrating, remembering or making decisions. If the response was “Yes” (1), a follow-up question (HE33) was asked to determine which household member(s) had difficulty concentrating, remembering or making decisions. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having serious cognitive difficulty, all family members were coded as “Don’t Know” (-8).

DFWLKC42 indicates whether a person has serious difficulty walking or climbing stairs. This variable was based on two questions, HE34 and HE35. The initial question (HE34) determined if anyone in the family had serious difficulty walking or climbing stairs. If the response was “Yes” (1), a follow-up question (HE35) was asked to determine which household member(s) had difficulty walking or climbing stairs. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having serious difficulty walking or climbing stairs, all family members were coded as “Don’t Know” (-8).

DFDRSB42 indicates whether a person has difficulty dressing or bathing. This variable was based on two questions, HE36 and HE37. The initial question (HE36) determined if anyone in the family had difficulty dressing or bathing. If the response was “Yes” (1), a follow-up question (HE37) was asked to determine which household member(s) had difficulty dressing or bathing. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having difficulty dressing or bathing, all family members were coded as “Don’t Know” (-8).

DFERND42 indicates whether a person has difficulty doing errands alone. This variable was based on two questions, HE38 and HE39. The initial question (HE38) determined if anyone in the family had difficulty doing errands alone. If the response was “Yes” (1), a follow-up question (HE39) was asked to determine which household member(s) had difficulty doing errands alone. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as having difficulty doing errands alone, all family members were coded as “Don’t Know” (-8).

2.5.6.5 Hearing Aids, Eyeglasses

A series of questions (HE40 to HE43) provides information on hearing aids and eyeglasses. These questions were asked of all household members, regardless of age. Deceased RU members were coded “Inapplicable” (-1).

HEARAD42 indicates whether a person wears a hearing aid. This variable was based on two questions, HE40 and HE41. The initial question (HE40) determined if anyone in the family wore a hearing aid. If the response was “Yes”, a follow-up question (HE41) was asked to determine which household member(s) wore a hearing aid. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” but no specific individual was identified as wearing a hearing aid, all family members were coded as “Don’t Know” (-8).

WRGLAS42 indicates whether a person wears eyeglasses or contact lenses. This variable was based on two questions, HE42 and HE43. The initial question (HE42) determined if anyone in the family wore eyeglasses or contact lenses. If the response was “Yes” (1), a follow-up question (HE43) was asked to determine which household member(s) wore eyeglasses or contact lenses. If the family-level response was “Don’t Know” (-8), “Refused” (-7), or “Not Ascertained” (-9), all persons were coded with the family-level response. In cases where the family-level response was “Yes” (1) but no specific individual was identified as wearing glasses or contact lenses, all family members were coded as “Don’t Know” (-8).

2.5.6.6 Any Limitation Rounds 3 and 5 (Panel 18) / Rounds 1 and 3 (Panel 19)

In FY 2013, the Round 2 and Round 4 variables (IADLHP42, ADLHLP42, SEEDIF42, and HEARDI42), which would be used to construct ANYLIM13 (ANY LIMITATION IN P17R3,4,5/P18R1,2,3) were dropped from the MEPS interview. Consequently, the variable ANYLIM13 was renamed ANYLMT13 (ANYLMT14 in 2014) and is now constructed from Rounds 1, 3, and 5 data only.

ANYLMT14 summarizes whether a person has any IADL, ADL, functional, or activity limitations in any of the pertinent rounds. This variable was derived based on data from Rounds 3 and 5 (Panel 18) or Rounds 1 and 3 (Panel 19). ANYLMT14 was built using the component variables IADLHP31, IADLHP53, ADLHLP31, ADLHLP53, WLKLIM31, WLKLIM53, ACTLIM31, and ACTLIM53. If any of these components was coded “Yes”, then ANYLMT14 was coded “Yes” (1). If all components were coded “No”, then ANYLMT14 was coded “No” (2). If all the components were “Inapplicable” (-1), then ANYLMT14 was coded as “Inapplicable” (-1). If all the components had missing value codes (i.e., -7, -8, -9, or -1), ANYLMT14 was coded as “Not Ascertained” (-9). If some components were “No” and others had missing value codes, ANYLMT14 was coded as “Not Ascertained” (-9). The exception to this latter rule was for children younger than five years old, who were not asked questions that are the basis for ACTLIM31 or ACTLIM53; for these RU members, if all other components were “No”, then ANYLMT14 was coded as “No” (2). The variable label for ANYLMT14 departs slightly from conventions. Typically, variables that end in “14” refer only to 2014. However, some of the variables used to construct ANYLMT14 were assessed in 2015, so some information from early 2015 is incorporated into this variable.

2.5.6.7 Child Health and Preventive Care

Questions were asked about each child (under the age of 18 excluding deceased children) in the applicable age subgroups to which they pertained. For the Child Supplement variables, a code of “Inapplicable” (-1) was assigned if a person was deceased, was not in the appropriate Round 2 or 4, or was not in the applicable age subgroup as of the interview date. This public use dataset contains variables and frequency distributions from the Child Health and Preventive Care Section associated with 10,378 children who were eligible for the Child Health and Preventive Care Section. Children were eligible for this section when PSTATS42 was not equal to 23, 24, 31 (Deceased) and 0 <= AGE42X <= 17. Of these children, 9,316 were assigned a positive person-level weight for 2014 (PERWT14F > 0). Cases not eligible for the Child Health and Preventive Care Section should be excluded from estimates made with the Child Health and Preventive Care Section.

Children’s General Health Status Questions (ages 0 - 17)

Through 2013, several questions from the General Health Subscale of the Child Health Questionnaire were asked about all children ages 0 through 17. A key reference for the Child Health Questionnaire is:

Landgraf JM, Abaetz L., Ware JE. The CHQ User’s Manual. First Edition. Boston, MA: The Health Institute, New England Medical Center, 1996.

Five questions asked for ratings of the child’s health on a 5-point scale, ranging from “Definitely True” (1) to “Definitely False” (5) and were dropped from the file in 2014. These questions were:

LSHLTH42 – child seems less healthy than other children
NEVILL42 – child has never been seriously ill
SICEAS42 – child usually catches whatever is going around
HLTHLF42 – expect child will have a healthy life
WRHLTH42 – worry more than is usual about child’s health

Children with Special Health Care Needs Screener (ages 0 - 17)

The Children with Special Health Care Needs (CSHCN) Screener instrument was developed through a national collaborative process as part of the Child and Adolescent Health Measurement Initiative (CAHMI) coordinated by the Foundation for Accountability. A key reference for this screener instrument is:

Bethel CD, Read D, Stein REK, Blumberg SJ, Wells N, Newacheck PW. Identifying Children with Special Health Care Needs: Development and Evaluation of a Short Screening Instrument. Ambulatory Pediatrics Volume 2, No. 1, January-February 2002, pp 38-48.

These questions are asked about children ages 0 –17. In general, the CSHCN screener identifies children with activity limitation or need or use of more health care or other services than is usual for most children of the same age. When a response to a gate question was set to “No” (2), “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained”
(-9), follow-up variables based on the gate question were coded as “Inapplicable” (-1).

The variable CSHCN42 identifies children with special health care needs, and was created using the CSHCN screener questions according to the specifications in the reference above. The CSHCN screener questions consist of a series of question-sequences about the following five health consequences: the need or use of medicines prescribed by a doctor; the need or use of more medical care, mental health, or education services than is usual for most children; being limited or prevented in doing things most children can do; the need or use of special therapy such as physical, occupational, or speech therapy; and the need or use of treatment or counseling for emotional, developmental, or behavioral problems. Parents who responded “yes” to any of the “initial” questions in the five-question sequences were then asked to respond to up to two follow-up questions about whether the health consequence was attributable to a medical, behavioral, or other health condition lasting or expected to last at least 12 months. Children with positive responses to at least one of the five health consequences along with all of the follow-up questions were identified as having a Special Health Care Need. Children with a “no” response for all five-question sequences were considered NOT to have a Special Health Care Need. Those children whose “special health care need” status could not be determined (due to missing data for any of the questions) were coded as “Unknown”. More information about the CSHCN screener questions can be obtained from (www.cahmi.org/wp-content/uploads/2014/06/CSHCNS-Fast-Facts.pdf).

The CSHCN screener questions were:

CHPMED42 – child needs or uses prescribed medicines
CHPMHB42 – prescribed medicines were because of a medical, behavioral, or other health condition
CHPMCN42 – health condition that causes a person to need prescribed medicines has lasted or is expected to last for at least 12 months
CHSERV42 – child needs or uses more medical care, mental health, or education services than is usual for most children of the same age
CHSRHB42 – child needs or uses more medical and other service because of a medical, behavioral, or other health condition
CHSRCN42 – health condition that causes a person to need or use more medical and other services has lasted or is expected to last for at least 12 months
CHLIMI42 – child is limited or prevented in any way in ability to do the things most children of the same age can do
CHLIHB42 – child is limited in the ability to do the things most children can do because of a medical, behavioral, or other health condition
CHLICO42 – health condition that causes a person to be limited in the ability to do the things most children can do has lasted or is expected to last for at least 12 months
CHTHER42 – child needs or gets special therapy such as physical, occupational, or speech therapy
CHTHHB42 – child needs or gets special therapy because of a medical, behavioral, or other health condition
CHTHCO42 – health condition that causes a person to need or get special therapy has lasted or is expected to last for at least 12 months
CHCOUN42 – child has an emotional, developmental, or behavioral problem for which he or she needs or gets treatment or counseling
CHEMPB42 – problem for which a person needs or gets treatment or counseling is a condition that has lasted or is expected to last for at least 12 months
CSHCN42 – identifies children with special health care needs

Columbia Impairment Scale (ages 5 - 17)

These questions inquired about possible child behavioral problems and were asked in previous years. Respondents were asked to rate on a scale from 0 to 4, where “0” indicates “No Problem” and “4” indicates “A Very Big Problem”, how much of a problem the child has with thirteen specified activities. A key reference for the Columbia Impairment Scale is:

Bird HR, Andrews H, et. al. “Global Measures of Impairment for Epidemiologic and Clinical Use with Children and Adolescents.” International Journal of Methods in Psychiatric Research, vol. 6, 1996, pp. 295-307.

Certain questions in this series were coded to “Asked, but Inapplicable” (99) when the question was not applicable for a specific child. For example, if a child’s mother was deceased, a question about how much of a problem a child has getting along with his/her mother would be set to “Asked, but Inapplicable” (99). Similarly, the question about problems getting along with siblings would be set to “Asked, but Inapplicable” (99) for children with no siblings. Variables in this set include:

MOMPRO42 – getting along with mother
DADPRO42 – getting along with father
UNHAP42 – feeling unhappy or sad
SCHLBH42 – (his/her) behavior at school
HAVFUN42 – having fun
ADUPRO42 – getting along with adults
NERVAF42 – feeling nervous or afraid
SIBPRO42 – getting along with brothers and sisters
KIDPRO42 – getting along with other kids
SPRPRO42 – getting involved in activities like sports or hobbies
SCHPRO42 – (his/her) schoolwork
HOMEBH42 – (his/her) behavior at home
TRBLE42 – staying out of trouble

CAHPS^® (Consumer Assessment of Healthcare Providers and Systems) ages 0 - 17

The health care quality measures were taken from the health plan version of CAHPS^®, an AHRQ sponsored family of survey instruments designed to measure quality of care from the consumer’s perspective. All of the CAHPS^® variables refer to events experienced in the last 12 months. The variables included from the CAHPS^® are:

CHEYRE42 – how often it was easy to see a specialist (coded as “-1 Inapplicable” when CHSPEC42 = 2, -7, -8, or -9).

Child Preventive Care (age range depends on question)

A series of questions was asked about amounts and types of preventive care a child may receive when going to see a doctor or other health provider. Questions are asked of children of different age groups depending on the nature of the questions. When a response to a gate question was set to “No” (2), “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), follow-up variables based on the gate question were coded as “Inapplicable” (-1). Variables in this set include:

TIMALN42 – during last health care visit, doctor or other health provider spent any time alone with the child (12 – 17)

Beginning in 2001, due to confidentiality concerns and restrictions, the variables HGTFT42, HGTIN42, WGTLB42, and WGTOZ42, were dropped from the Full-Year file. Instead, a Body Mass Index (BMI) variable, CHBMIX42, is calculated and included for children 6-17 years old. Due to a high percentage of missing height data for children ages 5 and under (34%), all children 5 and under were given a -1 “Inapplicable” code for the variable CHBMIX42. CHBMIX42 is included in the 2014 file and on the above list. Please note: analysts can have access to the height and weight variables and/or can construct a BMI variable of their own through the MEPS Data Center. To access information on the MEPS Data Center including an application, please go to the following Web address: meps.ahrq.gov/data_stats/onsite_datacenter.jsp.

The steps used to calculate the BMI for children 6-17 are as follows:

Construct child height and weight variables HGTFT42, HGTIN42, WGTLB42, and WGTOZ42 based on collected data
Create a preliminary data set containing height, weight, sex, and age data
Generate a preliminary child BMI using the preliminary data set and the procedure for calculating the BMI for children as described on the Centers for Disease Control and Prevention (www.cdc.gov) Web site
Create the child BMI variable CHBMIX42 using the preliminary child BMI, setting all deceased persons, all persons over 17 years old, and all persons 5 years old or younger to Inapplicable (-1)

Note that for FY 2014, child height and weight were not top-coded prior to the construction of the preliminary data set. Where height in feet was > 0 and height in inches was missing, the mid-point value for height in inches (6 inches) was assigned to HGTIN42 for use in the calculation of the child BMI. Where height in feet was 0 and height in inches was missing, the preliminary child BMI was set to “Not Ascertained” (-9).

For cases where weight in pounds was between 1 and 20 and weight in ounces was missing (WGTOZ42 in (-7, -8, -9)), the mid-point value for weight in ounces (8 ounces) was assigned to WGTOZ42 for use in the calculation of the child BMI. Where weight in pounds was 0 and weight in ounces was missing, the preliminary child BMI was set to “Not Ascertained” (-9).

This use of the mid-points for inches and ounces ensures that children who have feet but not inches in height and/or pounds but not ounces in weight are included in the BMI calculation.

As indicated in step 2 above, a preliminary SAS data set containing height, weight, sex, and age data for children 6-17 years old in FY 2014 was created. One SAS program and one SAS dataset were downloaded from the Centers for Disease Control and Prevention Web site for the purpose of calculating the BMI for children (step 3). The program used the preliminary data set of children to generate a preliminary child BMI based on the 2000 CDC growth charts (www.cdc.gov/growthcharts). The program used the following formula to calculate the preliminary BMI for children:

Weight in Kilograms / [(Height in Centimeters/100)]²

Note that weight in pounds and ounces was converted to weight in kilograms in the preliminary data set. Similarly, height in feet and inches was converted to height in centimeters in the preliminary data set.

As indicated in step 4 above, the child BMI variable CHBMIX42 was calculated using this preliminary BMI from step 3. Deceased persons, persons > 17 years old, and children younger than 6 years old were set to “Inapplicable” (-1) for CHBMIX42. Children 6-17 years old with a missing value for height in feet (HGTFT42 is “Refused” (–7), “Don’t Know” (-8), or “Not Ascertained” (-9)) and/or weight in pounds (WGTLB42 is “Refused” (–7), “Don’t Know” (-8), or “Not Ascertained” (-9)) were set to “Not Ascertained” (-9) for CHBMIX42. Children whose height in feet was 0 and height in inches was missing (HGTIN42 is “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9)) were set to “Not Ascertained” (-9) for CHBMIX42. Children whose weight in pounds was 0 and weight in ounces was missing (WGTOZ42 is “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9)) were set to “Not Ascertained” (-9) for CHBMIX42. All other children 6-17 years old have a calculated BMI for FY 2014.

CHBMIX42 is not top- or bottom-coded or edited.

For each of the variables above, a code of “Inapplicable” (-1) was assigned if the person was deceased or if the person did not belong to the applicable subgroups.

Beginning in FY 2013, BPMONT53 (# MOS SNCE LST BLOOD PRES CHK (>17)-R5/3) was dropped from this file.

A Body Mass Index (BMI) variable, BMINDX53, is calculated for adults 18 years of age or older. Please note: analysts can have access to the height and weight variables and/or construct a BMI variable of their own through the MEPS Data Center. To access information on the MEPS Data Center including an application, please go to the following Web address: meps.ahrq.gov/data_stats/onsite_datacenter.jsp.

BMI categories for adults are the following:

Underweight = BMI is less than 18.5,
Normal Weight = BMI is between 18.5 – 24.9 inclusive,
Overweight = BMI is between 25.0 – 29.9 inclusive, and
Obesity = BMI greater than or equal to 30.0

The following formula used to calculate the BMI for adults was taken from the Centers for Disease Control and Prevention (www.cdc.gov) Web site:

BMI = [Weight in Pounds / (Height in Inches)²] * 703

The steps used to calculate the BMI for adults are as follows:

Construct adult height, weight, and weight estimate variables HGHTFT53, HGHTIN53, WEIGHT53, and WGTEST53
Create the building block variable ADHGTIN, indicating total height in inches for adults => 18 years old
Create the temporary variable MIDWGT, indicating the mid-point value of a person’s estimate of weight (WGTEST53)
Create the adult BMI variable BMINDX53 using the building block and the temporary variable, setting all deceased persons and all persons < 18 years old to Inapplicable (-1)

Adult height and weight were not top- or bottom-coded prior to the construction of the adult BMI.

The building block variable ADHGTIN was calculated as [(HGHTFT53 * 12) + (HGHTIN53)] to indicate total adult height in inches, step 2. Note that ADHGTIN was created for programming efficiency only and is not included in this data release. For cases where height in feet was > 0 (HGHTFT53 > 0) and height in inches was missing (HGHTIN53 in (-7, -8, -9)), the mid-point value for height in inches (6 inches) was used in the calculation of total height in inches [ADHGTIN = (HGHTFT53 * 12) + 6]. This use of the mid-point for inches ensures that adults who have feet but not inches in height are included in the BMI calculation. ADHGTIN was set to Not Ascertained (-9) for all cases where adult height in feet was “Refused”, “Don’t Know”, or “Not Ascertained” (HGHTFT53 in (-7, -8, -9)). Deceased persons and persons whose age was less than 18 years old were set to Inapplicable (-1) for ADHGTIN.

The temporary variable MIDWGT was calculated to indicate the mid-point value of person’s estimate of weight (WGTEST53), step 3. Note that MIDWGT was created for programming efficiency only and is not included in this data release.

The adult BMI variable BMINDX53 was calculated (step 4) using the building block variable ADHGTIN and adult weight in pounds (WEIGHT53) as follows:

BMINDX53 = [WEIGHT53 / (ADHGTIN)²] * 703

For adults whose weight in pounds was “Don’t Know” (WEIGHT53 = -8) and whose estimate of weight was > 0 (WGTEST53 between 1 and 6), MIDWGT was used in the calculation of BMINDX53:

BMINDX53 = [MIDWGT / (ADHGTIN)²] * 703

BMINDX53 was set to “Not Ascertained” (-9) for adults whose weight in pounds was “Refused” or “Not Ascertained” (WEIGHT53 in (-7, -9)). BMINDX53 was set to “Not Ascertained” (-9) for adults whose weight in pounds was “Don’t Know” (-8) and whose estimate of weight was “Refused”, “Don’t Know”, or “Not Ascertained” (WGTEST53 in (-7, -8, -9)). BMINDX53 was set to “Not Ascertained” (-9) for adults whose total height in inches was “Not Ascertained” (ADHGTIN = -9). Deceased persons and persons whose age was less than 18 years old were set to “Inapplicable” (-1) for BMINDX53.

BMINDX53 is not top- or bottom-coded or edited.

2.5.6.9 2014 Self-Administered Questionnaire (SAQ)

The 2014 Self-Administered Questionnaire (SAQ), a paper-and-pencil questionnaire, was fielded during Panel 18 Round 4 and Panel 19 Round 2 of the 2014 Medical Expenditure Panel Survey (MEPS). The survey was designed to collect a variety of health status and health care quality measures of adults. All adults age 18 and older as of the Round 2 or 4 interview date (AGE42X >= 18) in MEPS households were asked to complete a SAQ. The questionnaires were administered in late 2014 and early 2015.

The variable SAQELIG indicates the person’s eligibility status for the SAQ. SAQELIG was used to construct the variables based on the SAQ data. SAQELIG was coded “0” (Not Eligible For SAQ) if there was no record for person in the round, if the person was deceased or institutionalized, moved out of the US, moved to a military facility, if the person’s disposition status was inapplicable, or if the person was less than 18 years old. SAQELIG was coded “1” (Eligible For SAQ and Has SAQ Data) if a SAQ record existed for the person in Round 2 (for Panel 19) or Round 4 (for Panel 18). SAQELIG was coded “2” (Eligible For SAQ, But No SAQ Data) if no SAQ record existed for the person in the round.

If a person was unable to respond to the SAQ, the questionnaire was completed by a proxy, indicated by the variable ADPRX42 (ADPRX42 > 0). For the SAQ variables, a code of “Inapplicable” (-1) was assigned if a person was not eligible or was eligible but no data existed based on SAQELIG (SAQELIG was coded “0” or “2”). If a person was not assigned a positive SAQ weight, all SAQ variables, with the exception of SAQELIG, were coded “Inapplicable” (-1). When a gate question answer was set to “No” (2), follow-up variables based on the gate question were coded as “Inapplicable” (-1). When a gate question answer was set to “Refused” (-7), “Don’t Know” (-8), or “Not Ascertained” (-9), follow-up variable answers were left as reported. A special weight variable (SAQWT14F) has been designed to be used with the SAQ for persons who were age 18 and older at the interview date. This weight adjusts for SAQ non-response and weights to the US civilian noninstitutionalized population (see Section 3.0 “Survey Sample Information” for details). The variables created from the SAQ begin with “AD”.

The language in which the SAQ was completed is indicated by the variable ADLANG42. If the English version of the SAQ was completed, ADLANG42 was coded “1” (English Version SAQ Was Administered). If the Spanish version of the SAQ was completed, or if the English version was translated into Spanish, ADLANG42 was coded “2” (Spanish Version SAQ Was Administered). If the language in which the SAQ was administered was not ascertained, ADLANG42 was coded “-9” (Not Ascertained).

The month and year the SAQ was completed are indicated by the variables ADCMPM42 and ADCMPY42, respectively.

Health Care Quality

CAHPS^® (Consumer Assessment of Healthcare Providers and Systems)

The health care quality measures in the SAQ were taken from the health plan version of CAHPS^®, an AHRQ-sponsored family of survey instruments designed to measure quality of care from the consumer’s perspective. All of the variables refer to events experienced in the last 12 months and were asked of adults age 18 and older. The variables included from the CAHPS^® are:

ADILCR42 – Had an illness, injury or condition needing care right away from a clinic, emergency room or doctor’s office
ADILWW42 – If ADILCR42 = 1, how often got care right away
ADRTCR42 – Any appointment was made with a doctor or clinic for health care
ADRTWW42 – If ADRTCR42 = 1, how often got an appointment for health care as soon as he or she thought it was needed
ADAPPT42 – Number of times went to doctor’s office or clinic to get care
ADNDCR42 – If ADAPPT42 > 0, whether you or a doctor believed you needed any care, tests, or treatment
ADEGMC42 – If ADAPPT42 > 0 and ADNDCR42= 1, how often it was easy to get care, tests or treatment you or a doctor believed necessary
ADLIST42 – If ADAPPT42 > 0, how often health providers listened carefully to you
ADEXPL42 – If ADAPPT42 > 0, how often health providers explained things in a way that was easy to understand
ADRESP42 – If ADAPPT42 > 0, how often providers showed respect for what you had to say
ADPRTM42 – If ADAPPT42 > 0, how often health providers spent enough time with you
ADINST42 – If ADAPPT42 > 0, whether doctors or other health providers gave instructions about what to do about a specific illness or health condition
ADEZUN42 – If ADINST42 = 1, how often the advice given by doctors or other health providers was easy to understand
ADTLHW42 – If ADINST42 = 1, how often doctors or other health providers asked you to describe how you are going to follow their instructions
ADFFRM42 – If ADAPPT42 > 0, whether had to fill out or sign any forms at the doctor’s office or other health provider’s office
ADFHLP42 – If ADFFRM42 = 1, how often you were offered help with filling out forms at the office
ADHECR42 – If ADAPPT42 > 0, rating of healthcare from all doctors and other health providers, from 0 (worst health care possible) to 10 (best health care possible)

General Health

ADSMOK42 – Currently smoke
ADNSMK42 – If ADSMOK42 = 1, doctor advised you to quit smoking
ADDRBP42 – Blood pressure has been checked by a doctor, nurse, or other health professional
ADSPEC42 – Needed to see a specialist
ADESSP42 – If ADSPEC42 = 1, how easy to see a specialist

Beginning with the FY13 Consolidated file, the variable name ADSPRF42 (SAQ 12MOS: HOW ESY GETTING SPEC REFERRAL) was replaced by ADESSP42 (SAQ 12MOS: HOW ESY TO SEE SPECIALIST).

Health Status

The SAQ contained three measures of health status: the Short-Form 12 Version 2 (SF-12v2 (r), a registered trademark), the Kessler Index (K6) of non-specific psychological distress, and the Patient Health Questionnaire (PHQ-2). Key references for these three measures are:

Ware, J.E., Kosinski, M., and Keller, S.D. (1996). A 12-item short-form health survey: Construction of scales and preliminary tests of reliability and validity. Medical Care 34:220.
Kessler, R.C., Andrews, G., Colpe, L.J., Hiripi, E., Mroczek, D.K., Normand, S.-L., Walters, E.E., and Zaslavsky, A.M. (2002). Short screening scales to monitor population prevalence and trends in non-specific psychological distress. Psychological Medicine 32: 959-976.
Kroenke, K., Spitzer, R.L., and Williams, J.B. (2003). The Patient Health Questionnaire-2: Validity of a two-item depressive screener. Medical Care 41: 1284-1292.

The SF-12v2 questions are as follows:

ADGENH42 – General health today
ADDAYA42 – During a typical day, limitations in moderate activities
ADCLIM42 – During a typical day, limitations in climbing several flights of stairs
ADPALS42 – During past 4 weeks, as result of physical health, accomplished less than would like
ADPWLM42 – During past 4 weeks, as result of physical health, limited in kind of work or other activities
ADMALS42 – During past 4 weeks, as result of mental problems, accomplished less than you would like
ADMWLM42 – During past 4 weeks, as result of mental problems, did work or other activities less carefully than usual
ADPAIN42 – During past 4 weeks, pain interfered with normal work outside the home and housework
ADCAPE42 – During the past 4 weeks, felt calm and peaceful
ADNRGY42 – During the past 4 weeks, had a lot of energy
ADDOWN42 – During the past 4 weeks, felt downhearted and depressed
ADSOCA42 – During the past 4 weeks, physical health or emotional problems interfered with social activities

Short-Form 12 Version 2 (SF-12v2)

In analyzing data from the SF-12v2, the standard approach is to form two summary scores based on responses to these questions. The scoring algorithms for both the Physical Component Summary (PCS) and the Mental Component Summary (MCS) incorporate information from all 12 questions. However, the PCS weights more heavily responses to the following questions: ADGENH42, ADDAYA42, ADCLIM42, ADPALS42, ADPWLM42, and ADPAIN42. The MCS weights more heavily responses to the following questions: ADDOWN42, ADCAPE42, ADMALS42, ADMWLM42, and ADSOCA42. The algorithm for computing the PCS and the MCS summary scores may be available through Optum™. For more information see www.optum.com/optum-outcomes/what-we-do/health-surveys/sf-12v2-health-survey.html

The PCS and MCS cannot be computed directly if a person has missing data for any of the twelve items. A proprietary method was used for imputing the PCS and MCS scores if some data are missing. PCS and MCS scores calculated according to the standard algorithm and incorporating imputations for some cases with missing data are available for analysts in this file. The PCS-12 score is PCS42, and the MCS-12 score is MCS42. Note that negative values are possible in PCS42 and MCS42 in rare cases. There are no records in 2014 where MCS42 or PCS42 is set to a negative value. Persons who were not eligible for the SAQ, or who were eligible but for whom no data existed based on SAQELIG, or who did not have a positive SAQ weight, were set to “Inapplicable” (-1) for PCS42 and MCS42. (These persons were set to missing in 2002.)

The variables PCS42 and MCS42 include cases in which the scores were imputed. SFFLAG42 indicates whether the physical component summary, PCS42, or the mental component, MCS42, was imputed for a respondent. In some cases the software could not impute a score due to amount of missing data; these cases have SFFLAG42 = 0 (No). (This represents a change from 2002, when these cases had SFFLAG42 = 1 (Yes)). Persons who were not eligible for the SAQ, or who were eligible but for whom no data existed based on SAQELIG, or who did not have a positive SAQ weight, were set to “Inapplicable” (-1) for SFFLAG42.

In 2000, 2001, and 2002, MEPS used Version 1 of the SF-12. The PCS and MCS scores based on Version 1 of the SF-12 in these years were based on norms from 1990. Version 2 scores are based on norms from a 1998 national study. To appropriately compare Version 1 scores with Version 2 scores, Version 1 scores need to be rescaled to 1998 norms. This can be done by adding 1.07897 to PCS scores from Version 1, and by subtracting 0.16934 from Version 1 MCS scores. For full details, please consult the SF-12 reference manual:

Ware, Jr., J.E., Kosinski, M., Turner-Bowker, DM, and Gandek, B. How to Score Version 2 of the SF-12 (r) Health Survey. (October, 2002). QualityMetric, Inc., Lincoln, RI.

Non-Specific Psychological Distress

The 2014 SAQ includes six mental health-related questions, using the “K-6” scale developed by R.C. Kessler and colleagues. These questions assess the person’s non-specific psychological distress during the past 30 days.

The non-specific psychological distress variables are as follows:

ADNERV42 – During the past 30 days, felt nervous
ADHOPE42 – During the past 30 days, felt hopeless
ADREST42 – During the past 30 days, felt restless or fidgety
ADSAD42 – During the past 30 days, felt so sad that nothing could cheer the person up
ADEFRT42 – During the past 30 days, felt that everything was an effort
ADWRTH42 - During the past 30 days, felt worthless

Kessler Index (K6)

A summary of the six variables above provides an index to measure non-specific, rather than disorder-specific, psychological distress, using the following values:

0 None of the Time
1 A Little of the Time
2 Some of the Time
3 Most of the Time
4 All of the Time

The index, called K6SUM42, is a summation of the values of the six variables above. The higher the value of K6SUM42, the greater the person’s tendency towards mental disability.

Patient Health Questionnaire (PHQ-2)

The 2014 SAQ includes two additional mental health questions. These questions assess the frequency of the person’s depressed mood and decreased interest in usual activities.

ADINTR42 – During the past two weeks, bothered by having little interest or pleasure in doing things
ADDPRS42 – During the past two weeks, bothered by feeling down, depressed, or hopeless

PHQ242 is a summation of the values of the two variables above, with scores ranging from 0 through 6. The higher the value of PHQ242, the greater the person’s tendency towards depression. Kroenke et al. (2004) suggest a score of 3 as the optimal cut point for screening purposes. Note that these items are intended as a screening measure for depression and are not equivalent to a DSM-V diagnosis of depression.

Attitudes about Health

The SAQ included four questions that ascertain certain health-related attitudes. Two items (ADINSA42 and ADINSB42) deal with attitudes toward health insurance. The other two questions (ADRISK42 and ADOVER42) deal with attitudes that might influence decisions to purchase health insurance or to use health services. No editing has been performed for these items.

ADINSA42 – Do not need health insurance
ADINSB42 – Health insurance is not worth the money it costs
ADRISK42 – More likely to take risks than the average person
ADOVER42 – Can overcome illness without help from a medically trained person

When using the SAQ and DCS variables in analysis, weights specific to each of these sets of questions should be used (SAQWT14F, DIABW14F). For persons who are not assigned a positive SAQ weight, the SAQ variables are recoded to “Inapplicable” (-1). Please see Section 3.0 “Survey Sample Information” for details.

2.5.6.10 Diabetes Care Survey (DCS)

The Diabetes Care Survey (DCS), a self-administered paper-and-pencil questionnaire, was fielded during Panel 18, Round 5 and Panel 19, Round 3. Households received a DCS based on their response to DIABDX in the Priority Conditions Enumeration (PE) section of the CAPI instrument, which asks whether the person was ever told by a doctor or health professional that he/she had diabetes. REFDIAB, collected at PC02A, allows the respondent to indicate that diabetes was reported in the PE section in error (REFDIAB = 2). Respondents were not prompted to confirm or deny the report of diabetes; REFDIAB was set to “2” (Person Does Not Have Diabetes) only if the respondent offered the information. DIABDX is set to “No” (2) and the DCS was not distributed to persons who reported diabetes in error.

The DCS asks the same question as DIABDX with responses summarized in the variable DSDIA53. DSDIA53 confirms that the person has ever been told by a health professional that he/she had diabetes or sugar diabetes. For a small number of cases DIABDX =YES (1) but DSDIA53 = NO (2). These people do not have a positive DCS weight. The DCS data are unedited, and, therefore, these and other data inconsistencies remain in the data. For all persons 17 years of age or younger, all the DCS variables are set to “Inapplicable” (-1) because there is not an appropriate weight included on the file to make national estimates for this population.

DSA1C53 indicates the number of times the respondent reported having a hemoglobin A1c blood test in 2014. Note that, prior to 2005, DSA1C53 did not reflect whether the person had a hemoglobin A1c blood test, only whether the person had a hemoglobin A1c test. DSFT1553, DSFT1453, DSFT1353, DSFB1353, and DSFTNV53 indicate whether the respondent reported having his or her feet checked for sores or irritations: in 2015, in 2014, in 2013, before 2013, or never, respectively. DSEY1553, DSEY1453, DSEY1353, DSEB1353 and DSEYNV53 indicate whether the respondent reported having an eye exam in which the pupils were dilated: in 2015, in 2014, in 2013, before 2013, or never, respectively. DSCH1553, DSCH1453, DSCH1353, DSCB1353, and DSCHNV53 indicate the last time the respondent reported having his or her blood cholesterol checked: in 2015, in 2014, in 2013, before 2013, or never, respectively. DSFL1553, DSFL1453, DSFL1353, DSVB1353, and DSFLNV53 indicate the when the person got a flu vaccination including the flu vaccine nasal spray: in 2015, in 2014, in 2013, before 2013, or never, respectively. DSKIDN53 and DSEYPR53 ascertain whether the diabetes has caused kidney or eye problems, respectively. DSDIET53, DSMED53, and DSINSU53 indicate if the respondent reported being treated for his/her diabetes by the following methods: diet, oral medications, or insulin, respectively.

The five variables that assess different ways the person with diabetes can learn about diabetes care are: DSCPCP53 (learned care from a primary care provider), DSCNPC53 (learned care from a provider not in the person’s primary care practice), DSCPHN53 (learned care from a phone call with a provider), DSCINT53 (learned care from reading about it on the internet), DSCGRP53 (learned care by taking a group class). Creation of these variables is based on the answer to a gate question, which asks, “During the last 12 months, have you learned how to take care of your diabetes?” Please note that there is no variable listed in the codebook to indicate the answer to that question, since it is only used for creation of the follow-up variables DSCPCP53, DSCNPC53, DSCPHN53, DSCINT53, and DSCGRP53. These follow-up variables are set to Inapplicable (-1) for persons who report not having learned how to take care of their diabetes during the last 12 months. The variable DSCONF53 indicates how confident the person is in treating his or her diabetes. Those variables that indicate a range of care outside the data year may represent persons with additional information included on the 2012 or the 2014 Full Year Consolidated PUF. Additional data for the second-year panel may be available on the 2012 PUF.

If a person was unable to respond to the DCS, the questionnaire was completed by a proxy (DSPRX53 = 1). A special weight variable (DIABW14F) has been designed to be used with DCS data. This weight adjusts for DCS nonresponse and weights to the number of diabetics in the US civilian noninstitutionalized population in 2014 (see Section 3.0 “Survey Sample Information” for details). Please note that the weighted frequencies displayed in the HC-171 codebook for the health status variables collected in the SAQ and DCS (as designated in the variable labels) are based on the full-year 2014 person weight PERWT14F. However, when using these variables in analysis, weights specific to each of these sets of questions should be used (SAQWT14F, DIABW14F). For persons who are not assigned a positive DCS weight, the DCS variables are recoded to “Inapplicable” (-1). Please see Section 3.0 “Survey Sample Information” for details.

2.5.7 Disability Days Indicator Variables (DDNWRK31-OTHNDD53)

The Disability Days (DD) section of the core interview contains questions about time lost from work or school because of a physical illness or injury, or a mental or emotional problem. Data were collected on each individual in the household. These questions were repeated in each round of interviews; this file contains data from Rounds 3, 4, and 5 of the MEPS Panel 18, initiated in 2013, and Rounds 1, 2, and 3 of the MEPS Panel 19, initiated in 2014. The number at the end of the variable name (31, 42, or 53) identifies the rounds in which the information was collected.

The reference period for these questions is the time period between the beginning of the panel or the previous interview date and the current interview date. In order to establish the length of a round, analysts are referred to the variables that indicate the beginning date and ending date of each round (BEGRFM##, BEGRFY##, ENDRFM##, and ENDRFY##). Analysts should be aware that Round 3 is conducted across years. The Disability Days variables reflect only the data pertinent to the calendar year (i.e., the current delivery year of 2014). Analysts who are interested in examining disability days data across years can link to other person-level PUFs using the DUPERSID.

The flow of the Disability Days section relies on the person’s age as of the interview date. Therefore, the round-specific constructed age variables (AGE31X, AGE42X, and AGE53X) are used to construct the comparable round-specific Disability Days PUF variables. Due to the age-specific nature of the Disability Days section, age data from other rounds are not used should the person’s age for the round be missing.

The variables DDNWRK31, DDNWRK42, and DDNWRK53 represent the number of times the person lost a half-day or more from work because of illness, injury, or mental or emotional problems during Rounds 31, 42, and 53, respectively. A response of “no work days lost” was coded zero; if the person did not work, these variables were coded -1 (Inapplicable). The analyst should note that there are cases where EMPST## = 1 or 2 (has current job or job to return to) where DDNWRK31/42/53 indicates work around the house only. This is because the responses to the Disability Days questions are independent of the responses to the employment questions. Persons who were less than 16 years old or whose age is missing (AGE##X is set to -1) were not asked about work days lost, thus these variables are also coded -1 (Inapplicable).

DDNSCL31, DDNSCL42, and DDNSCL53 indicate the number of times that a person missed a half-day or more of school during Rounds 31, 42, or 53, respectively. These questions were asked of persons aged 3 to 22; persons aged less than 3 or older than 22 and persons whose age is missing did not receive these questions and are coded as -1 on these variables (in a small number of cases this was not done for the 1996 data, the analyst will need to make this edit when doing longitudinal analyses). A code of -1 may also indicate that the person does not attend school. The analyst should be aware that there was no attempt to reconcile school days lost with the time of year (e.g., summer vacation). In order to establish time of year, analysts are referred to the variables that indicate the beginning date and ending date of each round (BEGRFM##, BEGRFY##, ENDRFM##, and ENDRFY##).

Beginning in FY 2013, the variables WRKINBED (Work Days Missed To Stay In Bed), SCLINBED (Missed Schl Days To Stay In Bed), DDBEDAYS (Other Days Spend In Bed Since Start Day), and the related variables WKBEDLYR (Work Days Missed To Stay In Bed Last Yr), SCBEDLYR (Missed Schl Days To Stay In Bed Last Yr), and BEDAYLYR (Other Days Spent In Bed Last Year) were not collected. Any conditions that could be created from these questions were not collected.

A final set of variables indicates if an individual took a half-day or more off from work to care for the health problems of another individual in the family. OTHDYS31, OTHDYS42, and OTHDYS53 indicate if a person missed work because of someone else’s illness, injury, or health care needs, for example to take care of a sick child or relative. These variables each have three possible answers: yes - missed work to care for another (coded 1); no – did not miss work to care for another (coded 2); or the person does not work (coded 2), based on the setting of the DDNWRK variable for the same round. Persons younger than 16 and persons whose age is missing were not asked these questions and are coded as -1 (in a small number of cases this was not done for the 1996 data, the analyst will need to make this edit when doing longitudinal analyses).

OTHNDD31, OTHNDD42, and OTHNDD53 indicate the number of days during each round in which work was lost because of another’s health problem. Persons younger than 16, those whose age is missing, those who do not work, and those who answer “no” to OTHDYS are skipped out of OTHNDD and receive codes of -1.

Note that, because Disability Days variables use only those Round 3 data pertinent to the data year, it is possible to have a person report missing work to care for the health problems of another individual (OTHDYS## = 1) but report no days missed (OTHNDD## = 0). This combination indicates that the person did not miss those work days during the data year. For OTHDYS31, a value of ‘0’ indicates that the person missed no work during the 2014 portion of Panel 18 Round 3 (i.e. any missed work days reported here occurred in the 2013 portion of Panel 18 Round 3). For OTHDYS53, a value of ‘0’ indicates that the person missed no work during the 2014 portion of Panel 19 Round 3 (i.e. any missed work days reported here occurred in the 2015 portion of Panel 19 Round 3).

Editing was done on these variables to preserve the skip patterns. No imputation was done for those with missing data.

2.5.8 Access to Care Variables (ACCELI42-PMDLRS42)

The variables ACCELI42 through PMDLRS42 describe data from the Access to Care (AC) section of the MEPS HC questionnaire, which was administered in Panel 18 Round 4 and Panel 19 Round 2. This supplement serves a number of purposes in the MEPS HC by gathering information on family members’ origins and preferred languages from 2002 to 2012; family members’ usual source of health care; characteristics of usual source of health care providers; access to and satisfaction with the usual source of health care provider; and access to medical treatment, dental treatment, and prescription medicines. The variable ACCELI42 indicates whether persons were eligible to receive the Access to Care questions. Persons with ACCELI42 set to ‘-1’ (Inapplicable) should be excluded from estimates made with the Access to Care data.

2.5.8.1 Family Members’ Usual Source of Health Care

For each individual family member, the AC section ascertains whether there is a particular doctor’s office, clinic, health center, or other place that the individual usually goes to if he/she is sick or needs advice about his/her health (HAVEUS42).

YNOUSC42 indicates the main reason why a person does not have a usual source of care (USC) provider. For those family members who do not have a USC provider, question AC07 ascertains the main reason why.

1 Seldom or Never Sick
2 Recently Moved to Area
3 Don’t Know Where to Go
4 USC in Area Not Available
5 Can’t Find Provider Who Speaks Language
6 Goes Different Places for Diff Needs
7 Just Changed Insurance Plans
8 Don’t Use Docs/Treat Self
9 Cost of Medical Care
10 No Health Insurance
91 Other Reason

If respondents choose ‘91’ (Other Reason) at AC07, they are asked at AC07OV to provide a verbal explanation of what the main reason is that they do not have a USC provider. These “text strings” can be recoded to one of the existing categorical values listed above or, if the frequency of the response warrants it, additional categorical values. Recoding is described in greater detail below.

Family members without a USC provider are then asked AC08, which ascertains whether there are any additional reasons why. The person may choose one or more reasons. A variable is constructed for each reason why:

NOREAS42 No Other Reason
SELDSI42 Seldom or Never Sick
NEWARE42 Recently Moved to Area
DKWHRU42 Don’t Know Where to Go
USCNOT42 USC in Area Not Available
PERSLA42 Can’t Find Provider Who Speaks Language
DIFFPL42 Goes Different Places For Diff Needs
INSRPL42 Just Changed Insurance Plans
MYSELF42 Don’t Use Docs/Treat Self
CARECO42 Cost of Medical Care
NOHINS42 No Health Insurance
OTHREA42 Other Reason

These variables reflect the answer categories given at AC08. If respondents choose ‘91’ (Other Reason) at AC08, they are asked at AC08OV to provide a verbal explanation of what the additional reason is that they do not have a USC provider. These “text strings” can be recoded to one of the existing yes/no variables listed above or, if the frequency of response warrants it, an additional yes/no variable. Recoding is described in greater detail below.

2.5.8.2 Characteristics of Usual Source of Health Care Providers

The AC section collects information about the different characteristics of each unique USC provider for a given family. If a person does not have a USC provider (HAVEUS42 is set to ‘2’ (No), ‘-7’ (Refused), ‘-8’ (Don’t Know) or ‘-9’ (Not Ascertained)), then these variables are set to ‘-1’ (Inapplicable).

The basis for the AC provider questions is PROVTY42. This variable indicates whether the person’s provider is a facility (‘1’), a person (‘2’), or a person-in-facility (‘3’). PROVTY42 is a copy of PROVTYPE (Provider Type) for persons who have a USC provider.

Depending on how PROVTY42 is set, persons are asked about the provider’s location, the provider’s personal characteristics (e.g., race), the provider’s accessibility, and the person’s satisfaction with the provider.

Provider Location

Two variables indicate the location of the provider. For facility or person-in-facility type providers, PLCTYP42 indicates whether the person’s facility is a Hospital Clinic/Outpatient Department (‘1’), a Hospital Emergency Room (‘2’), or a Non-Hospital Place (‘3’). According to CAPI flow, persons do not report the type of facility for person-type providers; therefore, if PROVTY42 is set to ‘2’ (Person), PLCTYP42 is set to ‘-1’ (Inapplicable). For all provider types, including person-type, LOCATN42 indicates whether the person’s provider is located in an Office (‘1’), a Hospital but Not the Emergency Room (‘2’), or a Hospital Emergency Room (‘3’).

Personal Characteristics of Providers

For person and person-in-facility type providers, TYPEPE42 indicates what type of doctor or other medical provider the person’s provider is. The possible values include:

1 MD – General/Family Practice
2 MD – Internal Medicine
3 MD – Pediatrics
4 MD – OB/Gyn
5 MD – Surgery
6 MD – Other
7 Chiropractor
8 Nurse
9 Nurse Practitioner
10 Physician’s Assistant
11 Other Non-MD Provider
12 Unknown
13 MD - Cardiologist
14 Doctor of Osteopathy
15 MD – Endocrinologist
16 MD – Gastroenterologist
17 MD – Geriatrician
18 MD – Nephrologist
19 MD – Oncologist
20 MD – Pulmonologist
21 MD – Rheumatologist
22 Psychiatrist / Psychologist
23 MD – Neurologist
24 Alternative Care Provider

TYPEPE42 is constructed using variables collected at several questions: AC15 “Is provider a medical doctor?” (PROV.MEDTYPE); AC16 “Is provider a nurse, nurse practitioner, physician’s assistant, midwife, or some other kind of person?” (PROV.OTHTYPE); and AC17 “What is provider’s specialty?” (PROV.MDSPECLT). If respondents choose ‘91’ (Other) at AC16 or AC17, they are asked at AC16OV or AC17OV, respectively, to provide a verbal explanation of the type of provider or medical doctor. These “text strings” can be recoded to one of the existing categorical values listed above or, if the frequency of the response warrants it, additional categorical values. Recoding is described in greater detail below.

The AC section also collects demographic information about person and person-in-facility type providers (PROVTY42 = 2 or 3). Six variables indicate the provider’s race: WHITPR42 (White), BLCKPR42 (Black/African American), ASIANP42 (Asian), NATAMP42 (Indian/Native American/Alaska Native), PACISP42 (Other Pacific Islander) and OTHRCP42 (Other Race). The respondent may choose more than one race for a single provider. These variables reflect the answer categories given at AC19. Prior to 2014, if respondents chose ‘91’ (Some Other Race) at AC19, they were asked at AC19OV to provide a verbal explanation of the provider’s race. These text strings could have been recoded to one of the existing yes/no variables listed above or an additional yes/no variable. Starting in 2014, AC19OV was removed from the MEPS and its “other specify” text string, PRVRACOS, is no longer collected.

In addition to the race variables, two other demographic variables are created: HSPLAP42 indicates whether the provider is Hispanic or Latino, and GENDRP42 indicates whether the provider is Male (‘1’) or Female (‘2’).

Using Constructed Variables to Describe the Usual Source of Care Provider

These variables describing a person’s USC provider can be used in combination to present a broader picture of the provider. For example, a person-in-facility provider with a particular person named who is a white, Hispanic, female pediatrician, with no other race specified, and whose location is in an office in a hospital is coded as:

PROVTY42 = 3
PLCTYP42 = 1
TYPEPE42 = 3
HSPLAP42 = 1
WHITPR42 = 1
BLCKPR42 = 2
ASIANP42 = 2
NATAMP42 = 2
PACISP42 = 2
OTHRCP42 = 2
GENDRP42 = 2
LOCATN42 = 1

2.5.8.3 Access to and Satisfaction with the Provider

The AC section collects information regarding the person’s ability to access the USC provider as well as the person’s satisfaction with the USC provider.

Access to the Provider

TMTKUS42 indicates how long it takes the person to travel to the USC provider: Less Than 15 Minutes (‘1’), 15 to 30 Minutes (‘2’), 31 to 60 Minutes (‘3’), 61 to 90 Minutes (‘4’), 91 Minutes to 120 Minutes (‘5’), or More than 120 Minutes (‘6’). Beginning in 2014, GOTOUS42, indicating how the person travels to the USC provider, was dropped from this file because the question was removed from the MEPS.

OFFHOU42, PHNREG42, and AFTHOU42 assess aspects of the provider that may make it difficult for the person to get in contact with the USC provider. OFFHOU42 indicates whether the provider has office hours at night or on the weekend. The remaining two variables reflect the person’s rating of the difficulty of accessing the USC provider by phone (PHNREG42), and after hours (AFTHOU42). The person has the following choices: Very Difficult (‘1’), Somewhat Difficult (‘2’), Not Too Difficult (‘3’), or Not at All Difficult (‘4’). DFTOUS42, difficulty of accessing the USC provider by travel, was dropped from this file beginning in 2014 because the question was removed from the MEPS.

Satisfaction with the Provider

These variables reflect the person’s confidence in, and satisfaction with, the USC provider. Four different facets of the person’s level of confidence in the USC provider are examined: Is the provider the person or place family members would go to for routine or minor health problems (MINORP42), preventive health care (PREVEN42), referrals to other health professionals (REFFRL42), or ongoing health problems (ONGONG42). The person’s level of satisfaction with the USC provider is examined in five ways: Does the USC provider: usually ask about prescription medications and treatments other doctors may give them (TREATM42), ask about and show respect for medical, traditional, and alternative treatments that the person is happy with (RESPCT42), ask the person to help make decisions between a choice of treatments (DECIDE42), present and explain all options to the person (EXPLOP42), and speak the person’s language or provide translator services (PRVSPK42).

Prior to FY 2013, LANGPR42 was delivered based on AC31 (Does {someone at} PROVIDER speak the language [person] prefer(s) or provide translator services for them?). In FY 2013, two variables were delivered, LANGPR42 for Panel 17 and PRVSPK42 for Panel 18 to follow instrument design changes. Starting in FY 2014, PRVSPK42 only was constructed for both panels, based on AC31.

PRVSPK42 is set to a value other than ‘-1’ (Inapplicable) for persons eligible for the Access to Care supplement, who had a usual source of care, and were identified as speaking a language other than English at home (OTHLANG = ‘1’) and speaking English either “Not Well” or “Not at All” (HWELLSPE = ‘3’ or ‘4’). PRVSPK42 is set to ‘-1’ for all persons not meeting these criteria or who were deceased, institutionalized, or younger than 5 years of age.

If the person was under 5 years old in Round 1 and age 5 in Panel 19 Round 2 or Panel 18 Round 4, the source data are missing per design. For these records, PRVSPK42 was set to ‘-1’ (Inapplicable).

2.5.8.4 Access to Medical Treatment, Dental Treatment, and Prescription Medicines

The Access to Care supplement gathers information on family members’ abilities to receive treatment and receive it without delay. These questions are split into three sections inquiring about medical, dental, and prescription medicine treatments. Each section inquires whether the person was unable to receive treatment (MDUNAB42, DNUNAB42, PMUNAB42) or was delayed in receiving treatment (MDDLAY42, DNDLAY42, PMDLAY42). A value of ‘1’ (Yes) for these two sets of variables indicates that the person needed treatment but was unable to receive it or was delayed in receiving it. A value of ‘2’ (No) for these two sets of variables indicates that either the person did not need treatment or the person needed treatment and was able to receive it without delay. If the person was unable to receive treatment, the respondent was asked why (MDUNRS42, DNUNRS42, PMUNRS42). Respondents were also asked why there was delay in receiving treatment (MDDLRS42, DNDLRS42, PMDLRS42). Possible reasons include:

1 Could Not Afford Care
2 Ins Co Would Not Approve/Cover/Pay
3 Doctor Refused Family Ins Plan
4 Problems Getting To Doctor’s Office
5 Different Language
6 Could Not Get Time Off Work
7 DK Where To Go To Get Care
8 Was Refused Services
9 Could Not Get Child Care
10 Did Not Have Time or Took Too Long
91 Other

Through 2013, respondents were also asked how much of a problem was not receiving treatment (MDUNPR42, DNUNPR42, PMUNPR42) or being delayed in receiving treatment (MDDLPR42, DNDLPR42, PMDLPR42). These questions were removed for 2014, and these six variables were not constructed.

2.5.8.5 Editing the Access to Care Variables

Editing consisted primarily of logical editing for consistency with skip patterns. Other editing included the construction of new response values and new variables describing the recoding of several “other specify” text items into existing or new categorical values, which are described below.

In previous years, not all variables or categories that appear in the Access to Care section of the HC questionnaire are included on the file, as some small cell sizes have been suppressed to maintain confidentiality. No variable or category was suppressed in 2014.

Return To Table Of Contents

2.5.8.6 Recoding of Additional Other Specify Text Items

For Access to Care items AC07, AC08, AC16, and AC17, the “other specify” text responses were reviewed and coded as an existing or new value for the related categorical variable (for AC07, AC16, and AC17), or coded as an existing or new “yes/no” variable (for item AC08). Note that, starting in 2005, additional categories and variables are retained for low frequency responses to allow for pooling data. Beginning in 2014, AC19OV was removed from the MEPS and its “other specify” text string, PRVRACOS, is no longer collected.

In 2009, No Health Insurance was added as category ‘10’ at AC07 and AC08 for the main reason and for another reason why a person does not have a usual source of care. In order to distinguish between category ‘10’ selected within CAPI (No Health Insurance) and category ‘10’ in recoding (Other Insurance Related Reason), the recoding category for Other Insurance Related Reason was updated to category ‘24’. In order to compare data from 2009 or later with data previous to 2009, users can compare a combination of the CAPI category ‘10’ and recoding category ‘24’ for 2009 or later with the previous recoding category ‘10’ alone.

The following are the additional codes or variables which were created from these “other specify” text responses.

For item AC07 (“What is the main reason person does not have a usual source of health care”), the following additional values were available for the variable YNOUSC42:

11 Job-Related Reasons
12 Looking for a New Doctor
13 Doctor is Located Elsewhere
14 Don’t Like/Don’t Trust Doctors
15 Health-Related Reasons
16 Newborn-No Doctor Yet
17 Self, Relative, or Friend is a Doctor
19 Care Available on Job
20 Will Not Go to the Doctor
21 Problems with Time and Transportation
22 Person Goes to a Hospital, Clinic, or Emergency Room
23 Uses Alternative Care
24 Other Insurance Related Reason

For item AC08 (“What are the other reasons person does not have a usual source of health care”), the following additional variables were constructed:

OTHINS42 For Other Insurance Reasons;
JOBRSN42 For Job-Related Reasons;
NEWDOC42 Is Looking for a Doctor;
DOCELS42 Doctor is Located Elsewhere;
NOLIKE42 Does Not Like Doctor;
HEALTH42 Health-Related Reasons;
KNOWDR42 The Person Knows or is a Doctor;
ONJOB42 Works with Medical Personnel;
NOGODR42 Person Will Not Go to the Doctor;
TRANS42 The Person Had Problems Finding Transportation or Time;
CLINIC42 The Person Goes to a Hospital, Clinic, or Emergency Room;
NOHINS42 No Health Insurance.

OTHTYPE and MDSPECLT are used to construct the variable TYPEPE42. Unlike the other recoded variables, these variables’ text strings can be recoded to each other’s categories. For example, for persons who indicate that their USC provider is not a medical doctor (PROV.MEDTYPE = 2), the other type of USC provider is other (PROV.OTHTYPE = 91), and the text string collected is “GYNECOLOGIST”, TYPEPE42 would be set to ‘4’ (MD – OB/GYN) instead of ‘11’ (OTHER NON-MD PROVIDER.)

Text responses at AC19 were not coded as new responses or new variables.

2.5.9 Employment Variables (EMPST31-OFREMP53)

Employment questions were asked of all persons 16 years and older at the time of the interview. Employment variables consist of person-level indicators such as employment status and job-related variables such as hourly wage. All job-specific variables refer to a person’s current main job. The current main job, defined by the respondent, indicates the main source of employment.

Most employment variables pertain to the round interview date. The round dates are indicated by two numbers following the variable name; the first number representing the round for Panel 18 persons, the second number representing the round for Panel 19 persons. For example, EMPST31 refers to employment status on the Round 3 interview date for Panel 18 persons and employment status on the Round 1 interview date for Panel 19 persons.

With the exception of some health insurance and wage variables, no attempt has been made to logically edit any employment variables. When missing, values were imputed for certain persons’ hourly wages. Due to confidentiality concerns, hourly wages greater than or equal to $78.00 were top-coded to -10 and the number of employees variable was top-coded at 500. With the exception of a variable indicating whether the employer has more than one location (MORE), all employer-specific variables refer to the establishment that is the location of a person’s current main job.

The MEPS employment section used dependent interviewing in Rounds 2 through 5. If employment status and certain job characteristics did not change from the previous round, as identified in the Review of Employment (RJ) section, the respondent was skipped through the main employment section. A code of “–2” is used to indicate that the information in question was obtained in a previous round. For example, if the HRWG42X (Round 4 interview date hourly wage for Panel 18 persons or Round 2 interview date hourly wage for Panel 19 persons) is coded as “–2”, refer to HRWG31X (Round 3 interview date hourly wage for Panel 18 persons or Round 1 interview date hourly wage for Panel 19 persons) for the value for HRWG42X. Note that there may be a value for the Round 3/1 hourly wage or there may be an “Inapplicable” code (-1). The “-2” value for HRWG42X indicates that the person was skipped past the question at the time of the subsequent interview. To determine who should be skipped through various employment questions, certain information, such as employment status, had to be asked in every round and, thus, “-2” codes do not apply to employment status. Additionally, information on whether the person currently worked at more than one job or whether the person held health insurance from a current main employer was asked in every round, and, therefore, those variables also have no “-2” codes.

For Panel 18 persons who have a current main job in Round 3 that continues from Round 1 or 2, the “-2” code is not sufficient for those variables that the person was skipped past at the time of the interview. This is because the Panel 18 Round 1 and 2 data are not included on this release and therefore there are no data to refer to. For such persons, the values for the variables for these skipped questions are copied from the Round 1 or 2 constructed variable on the 2013 Full Year Public Use Release, depending on the round in which the job first became the current main job. The accompanying variable RNDFLG31 indicates the round in which these data were collected. For example, if the person has a Round 3 current main job that continues from Round 2 and was first reported as the current main job in Round 2, HRWG31X will be a copy of the HRWG42X variable from the 2013 Full Year Public Use Release and RNDFLG31 will be “2”, indicating the round in which the job was first reported as the current main job.

Employment Status (EMPST31, EMPST42, and EMPST53)

Employment status was asked for all persons age 16 or older. Allowable responses to the employment status questions were as follows:

“currently employed” if the person had a job at the interview date;
“has a job to return to” if the person did not work during the reference period but had a job to return to as of the interview date;
“employed during the reference period” if the person had no job at the interview date but did work during the round;
“not employed with no job to return to” if the person did not have a job at the interview date, did not work during the reference period, and did not have a job to which he or she could return.

These responses were mutually exclusive. A current main job was defined for persons who either reported that they were currently employed and identified a current main job or who reported and identified a job to return to. Therefore, job-specific information such as hourly wage exists for persons not presently working at the interview date but who have a job to return to as of the interview date.

The analyst should note that there are cases where EMPST## = 1 or 2 (has current job or job to return to) where DDNWRK31/42/53 indicates work around the house only. This is because the responses to the Disability Days questions are independent of the responses to the employment questions.

Data Collection Round for Round 3/1 CMJ (RNDFLG31)

As mentioned above, for Panel 18, if a person’s Round 3 current main job (CMJ) is a continuation CMJ from Round 2 or Round 1, the value of most “31” variables will be copied forward from the variable representing the round in which the job was first reported as the CMJ. For persons in Panel 18, RNDFLG31 indicates the round in which the Round 3 CMJ was first reported as the CMJ and provides a timeframe for the reported wage information and other job details. RNDFLG31 is used with many “31” variables to indicate the round on which the reported information is based.

RNDFLG31 is set to “Inapplicable” (–1) for persons in either panel who are under age 16 or who do not have a CMJ in Panel 18 Round 3 or Panel 19 Round 1. For persons who are part of Panel 18, RNDFLG31 is also set to “Inapplicable” (–1) if the person is out-of-scope in the 2014 portion of Round 3. For persons who are part of Panel 19, RNDFLG31 is also set to “Inapplicable” (–1) if the person is out-of-scope in Round 1. For persons who are part of Panel 18, other values for RNDFLG31 are set as follows:

1 continuing Round 3 CMJs reported first in Round 1;
2 continuing Round 3 CMJs reported first in Round 2;
3 jobs newly reported as current main in Round 3;
-9 Round 3 CMJ is a continuation CMJ (wage information and other details were not collected in Round 3) but the Round 2 CMJ record either does not exist or is not the same job. This can occur in rare instances because corrections made to a person’s record in a current file cannot be made to that record in an earlier file due to data base processing constraints. Corrections are made based on respondent comments in subsequent rounds that affect employment information previously reported.

For persons who are part of Panel 19 and reported a Round 1 CMJ, RNDFLG31 is set to “1” indicating that the job information represented in the “31” variables was collected in Round 1.

Self-Employed (SELFCM31, SELFCM42, and SELFCM53)

Information on whether an individual was self-employed at the current main job was obtained for all persons who reported a current main job. Certain questions, namely those regarding benefits and hourly wage, were not asked of the self-employed. Variables constructed from these questions indicate whether the establishment reported by wage earners (those not self-employed) as the main source of employment offered any of the following benefits:

Paid leave to visit a doctor (PAYDR31, PAYDR42, and PAYDR53)
Paid sick leave (SICPAY31, SICPAY42, and SICPAY53)
Paid vacation (PAYVAC31, PAYVAC42, and PAYVAC53)
Pension plan (RETPLN31, RETPLN42, and RETPLN53)

For persons who were self-employed at their current main job, these benefits variables were coded as “Inapplicable” (-1). Additionally, information on whether the firm had more than one business location (MORE31, MORE42, and MORE53) and whether the establishment was a private for-profit, nonprofit, or a government entity (JOBORG31, JOBORG42, and JOBORG53) was not applicable for self-employed persons. Conversely, the variables that identify whether a business was incorporated, a proprietorship, or a partnership (BSNTY31, BSNTY42, and BSNTY53) applied only to those who were self-employed at their current main job.

Hourly Wage (HRWG31X, HRWG42X, HRWG53X), Wage Update Variable (DIFFWG31, DIFFWG42, DIFFWG53), and Updated Hourly Wage (NHRWG31, NHRWG42, NHRWG53)

Hourly wage was asked of all persons who reported a current main job that was not self-employment (SELFCM). HRWG31/42/53X provide the wage amount reported initially for a person’s current main job. If a current main job continues into subsequent rounds DIFFWG31/42/53 indicate if the wage has changed since the previous round. If the job continues and there is a different wage at that job, NHRWG31/42/53 indicate the new wage amount.

Some wage information was logically edited for consistency. Edits were performed under two circumstances:

in some cases where wages reported as less than $1.00 per hour are updated in a subsequent round to greater than $1.00, and the wage increased by a factor of 10 or 100 (for example, if a Round 4 wage is updated to $20.00, the Round 3 wage of $0.20 could logically be updated to $20.00); in some of these cases, additional comments may have also indicated an error
in some cases where wages changed substantially from round to round and a keying error was evident (for example, ‘the number of hours on which the salary is based’ is updated from ‘40’ to ‘4’; the ‘4’ could logically be updated to ‘40’)

In all cases that result in an edit, a complete review of wage and employment history is performed; in some cases, comparisons are made to employment at similar establishments within the MEPS as well as to data reported and summarized by the Bureau of Labor Statistics.

The initial hourly wage variables (HRWG31X, HRWG42X, HRWG53X) on this file should be considered along with their accompanying variables – HRHOW31, HRHOW42, and HRHOW53 – which indicate how the respective round hourly wage was constructed. Hourly wage could be derived, as applicable, from a large number of source variables. In the simplest case, hourly wage was reported directly by the respondent. For other persons, construction of the hourly wage was based upon salary, the time period on which the salary was based, and the number of hours worked per time period. If the number of hours worked per time period was not available, a value of 40 hours per week was assumed, as identified in the HRHOW variable.

The initial hourly wage variable HRWG31/42/53X was imputed using a weighted sequential hot-deck procedure for those identified as having a current main job who were not self-employed and who did not know their wage or refused to report a wage. Hourly wage for persons for whom employment status was not known was coded as “Not Ascertained” (-9). Additionally, wages were imputed for wage earners reporting a wage range and not a specific value. For each of these persons, a value was imputed from other persons on the file who did report a specific value that fell within the reported range. The variables HRWGIM31, HRWGIM42, and HRWGIM53 identify persons whose wages were imputed. Note that wages were imputed only for persons with a positive person and/or positive family weight.

The variable DIFFWG31/42/53 indicates whether a person’s wage amount was different in the current round at a continuing, current main job. NHRWG31/42/53 contains the updated wage amount in cases where a person indicates a change in wages (DIFFWG = 1). While the question regarding wage changes pertains to the primary wage at the main job, occasionally respondents update a person’s supplemental wage at the main job. In these cases, users should note that HRWG31/42/53X and NHRWG31/42/53 may not differ. Users may wish to refer to the 2014 Full-Year Jobs PUF to obtain the reason for the wage change by linking on DUPERSID for the appropriate round.

For all Panel 19 Round 1 persons, DIFFWG31 and NHRWG31 are set to ‘inapplicable’ because this was the first round that wages could be reported for those persons. In Rounds 2 through 5, no imputation was performed on NHRWG31/42/53. Instead, where an updated wage amount is ‘not known’ or is ‘refused,’ NHRWG31/42/53 is set to ‘not ascertained.’ For persons whose hourly wage variable HRWG31/42/53X was imputed and the respondent provides an updated wage amount in a subsequent round, the new wage, NHRWG31/42/53, is not presented. Instead, NHRWG31/42/53 is set to ‘-13’ to indicate that the initial HRWG31/42/53X was imputed. Users may wish to refer to the 2014 Full-Year Jobs PUF to obtain updated wage amounts for these jobs.

For reasons of confidentiality, the hourly wage variables were top-coded. A value of –10 indicates that the hourly wage was greater than or equal to $78.00. As of Full-Year 2004, the wage top-code process used the highest reported wage on the file for an individual regardless of whether it was reported in an HRWG31/42/53X or NHRWG31/42/53X variable. Prior to Full-Year 2004, only the initial reported wage in Rounds 3 or 1 (HRWG31X) was used to calculate the wage top-code amount. Also beginning with the 2004 file, all wages for a person were top-coded if any wage variable was above the top-code amount.

In order to protect the confidentiality of persons across deliveries, the same top-code amount used in this Full-Year Use file was also applied to the Full-Year 2014 Jobs file. Because a person can have other jobs besides a current main job which are included in the corresponding 2014 Full Year Jobs PUF, wages at these other jobs were reviewed in the top-coding process. In some cases for these persons, wages reported at the current main job were below the top-code amount while the wage at another job had to be top-coded. To further protect the confidentiality of such persons across deliveries, wages reported at all jobs in the Full-Year 2014 Jobs PUF were top-coded and the wages at their current main job (HRWG31/42/53X and NHRWG31/42/53) included in this file were also top-coded.

Health Insurance (HELD31X, HELD42X, HELD53X, OFFER31X, OFFER42X, OFFER53X, CHOIC31, CHOIC42, CHOIC53, DISVW31X, DISVW42X, DISVW53X, OFREMP31, OFREMP42, OFREMP53)

There are several employment-related health insurance measures included in this release: health insurance held at a current main job (HELD31X, HELD42X, HELD53X), health insurance offered through a current main job (OFFER31X, OFFER42X, OFFER53X), and a choice of health plans available through the current main job (CHOIC31, CHOIC42, CHOIC53).

Several persons indicated that they held health insurance through a current main job in the employment section and then denied this coverage later in the interview in the health insurance section. Employment section health insurance HELD variables were edited for consistency to match the health insurance measures obtained in the health insurance section. To allow for easy identification of these individuals, round-specific flag variables were constructed (DISVW31X, DISVW42X, DISVW53X).

Responses in the employment section for health insurance held were recoded to be consistent with the variables in the health insurance section of the survey. Due to questionnaire skip patterns, the responses to health insurance offered were affected by editing the HELD variable. For example, if a person responded that health insurance was held from a current main job, the question relating to whether health insurance was offered was skipped. For persons who responded in the employment section that they held health insurance coverage and then disavowed the coverage in the health insurance section, it could not be ascertained whether they were offered a policy. These individuals are coded as –9 for the OFFER variables.

In the first round in which a person is reported as having a specific CMJ, MEPS asks if the person holds health insurance through that job. If the person does not hold insurance, then a follow-up question is asked as to whether the person was offered insurance (but declined coverage). However, if a person does hold insurance, then that person is skipped over the offered question and the offer variable (OFFER31X, OFFER42X, OFFER53X) is automatically set to “Yes” (1).

In the rounds after a CMJ is initially reported, the “held” question is asked again in each interview (whether a person now holds insurance). This is to determine if there has been any change in coverage. For persons with a continuing job who did not have coverage in the current round, the respondent is asked if the person was offered insurance. This current round information can also affect the setting of the DISVW variable as well.

In addition to this modification to OFFER, MEPS includes several clarifying questions regarding insurance availability to the jobholder through an employer. When a respondent indicates that the jobholder neither held nor was offered health insurance at the job, the respondent is asked if any other employees at the job were offered health insurance. The variable OFREMP31/42/53 indicates whether an employer offered health insurance to other employees at a firm. As of FY 2013, MEPS no longer collects information indicating the reason a jobholder is not eligible for coverage. Consequently, YNOINS31, YNOINS42, and YNOINS53 have been removed from this file.

Data users should note that OFREMP31/42/53 is automatically set to ‘1’ in cases where HELD and OFFER are ‘1,’ thus indicating that the jobholder has health insurance coverage through the employer, that coverage is offered to the employee, and that the employer offers insurance to its employees.

The employment-related insurance variables, HELD, OFFER, DISVW, and OFREMP for each round are logically edited for consistency.

Hours (HOUR31, HOUR42, HOUR53)

The hours measure refers to usual hours worked per week at the current main job. Note that, in cases where the respondent estimated hours worked per week at 35 hours or more, HOUR31, HOUR42, and HOUR53 were set to ‘40.’

Temporary (TEMPJB31, TEMPJB42, TEMPJB53) and Seasonal (SSNLJB31, SSNLJB42, SSNLJB53) Jobs

The temporary job variables (TEMPJB31, TEMPJB42, TEMPJB53) indicate whether a newly reported current main job lasts for only a limited amount of time or until the completion of a project.

The seasonal job variables (SSNLJB31, SSNLJB42, SSNLJB53) indicate whether the newly reported current main job is only available during certain times of the year. SSNLJB is “YES” (‘1’) if the job is only available during certain times of the year, SSNLJB is “NO” (‘2’) if the job is year round. Teachers and other school personnel who work only during the school year are considered to work year round.

Both variables are set on current main jobs whether a person is self-employed or not. Beginning FY 2013, MEPS no longer asks in each round whether a job is temporary or if it is seasonal. Instead, these questions are asked only in the round the job is newly reported. Consequently, in rounds following the initial report, a code of ‘-2’, “Determined In Previous Round”, is used to indicate that the information in the question was obtained in a previous round. This differs from previous files where both questions were asked in each round and ‘-2’ was not an allowed value.

Number of Employees (NUMEMP31, NUMEMP42, NUMEMP53)

NUMEMP indicates the number of employees at the location of the person’s current main job. Due to confidentiality concerns, this variable indicating the number of employees at the establishment has been top-coded at 500 or more employees. For persons who reported a categorical size, a median estimated size from donors within the reported range is used.

Other Employment Variables

Information about industry and occupation types for a person’s current main job at the interview date is also contained in this release. Based on verbatim text fields collected during the interview, numeric industry and occupation codes are assigned by trained coders at the Bureau of the Census. Beginning in 2010, Census uses 2007 Census Industry and 2010 Census Occupation Coding schemes instead of the 2003 versions used from FY2002 through FY2009. Both coding schemes were developed for the Bureau’s Current Population Survey and American Community Survey. Users should note that coding schemes are comparable for the FY2002 through FY2009 data files. Earlier versions of Census coding schemes were used on files prior to FY2002.

Current main jobs were initially coded at the 4-digit level for both industry and occupation. Then, for confidentiality reasons, these codes were condensed into broader groups for release on the file. INDCAT31, INDCAT42, and INDCAT53 represent the condensed industry codes for a person’s current main job at the interview date. OCCCAT31, OCCCAT42, and OCCCAT53 represent the condensed occupation codes for a person’s current main job at the interview date.

This release incorporates crosswalks showing how the detailed 2007 Census industry and 2010 Census occupation codes were collapsed into the condensed codes on the file, in both HTML and PDF formats. The schemes used in this file can be linked directly to the 2007 North American Industry Code System (NAICS) and the 2010 Standard Occupation Code scheme (SOC) by going to the Bureau of the Census website where a variety of additional crosswalks is also available: http://www.census.gov/people/io/.

Information indicating whether a person belonged to a labor union (UNION31, UNION42, and UNION53) is also contained in this release.

The month and year that the current main job started for Rounds 3, 4, and 5 of Panel 18 and Rounds 1, 2, and 3 of Panel 19 are provided in this release (STJBMM31, STJBYY31, STJBMM42, STJBYY42, STJBMM53, and STJBYY53). To protect the confidentiality of jobholders, as of FY 2013, the variables indicating the start day of a current main job (STJBDD31, STJBDD42, and STJBDD53) have been removed from this file.

There are two measures included in this release that relate to a person’s work history over a lifetime. One indicates whether a person ever retired from a job as of the Round 5 interview date for Panel 18 persons or the Round 3 interview date for Panel 19 persons (EVRETIRE). The other indicates whether a person ever worked for pay as of the Round 5 interview date for Panel 18 persons or the Round 3 interview date for Panel 19 persons (EVRWRK). The latter was asked of everyone who indicated that they were not working as of the round interview date. Therefore, anyone who indicated current employment or who had a job during any of the previous or current rounds was skipped past the question identifying whether the person ever worked for pay. These individuals were coded as “Inapplicable” (-1). All persons who ever reported a job and were 55 years or older as of the round interview date were asked if they “ever retired”. Since both of these variables are not round specific, there are no “-2” codes.

This release contains variables indicating the main reason a person did not work since the start of the reference period (NWK31, NWK42, and NWK53). If a person was not employed at all during the reference period (at the interview date or at any time during the reference period) but was employed some time prior to the reference period, the person was asked to choose from a list the main reason he or she did not work during the reference period. The “Inapplicable” (-1) category for the NWK variables includes:

Persons who were employed during the reference period;
Persons who were not employed during the reference period and who were never employed;
Persons who were out-of-scope the entire reference period and;
Persons who were less than 16 years old.

A measure of whether an individual had more than one job on the round interview date (MORJOB31, MORJOB42, and MORJOB53) is provided on this release. In addition to those under 16 and those individuals who were out-of-scope, the “Inapplicable” category includes those who did not report having a current main job. Because this is not a job-specific variable, there are no “–2” codes.

This release contains variables indicating if a current main job changed between the third and fourth rounds for Panel 18 persons or between the first and second rounds for Panel 19 persons (CHGJ3142) and between the fourth and fifth rounds for Panel 18 persons or between the second and third rounds for Panel 19 persons (CHGJ4253). In addition to the “Inapplicable”, “Refused”, “Don’t Know”, and “Not Ascertained” categories, the change job variables were coded to represent the following:

1 person left previous round current main job and now has a new current main job;
2 person still working at the previous round’s current main job but, as of the new round, no longer considers this job to be the current main job and defines a new main job (previous round’s current main job is now a current miscellaneous job);
3 person left previous round’s current main job and does not have a new job;
4 person did not change current main job.

Finally, this release contains the reason given by the respondent for the job change (YCHJ3142 and YCHJ4253). The reasons for a job change were listed in the CAPI questionnaire and a respondent was asked to choose the main reason from this list. In addition to those out-of-scope, those under 16, and those not having a current main job, the “Inapplicable” category for YCHJ3142 and YCHJ4253 includes workers who did not change jobs.

Employment Variables Imputed for Missing Values (EMPST31H – RTPLN53H)

To further assist analysts, a series of fully-imputed employment variables is now available on the 2014 Full Year Consolidated Data File (FY PUF). For the years 2000 to 2013 these variables can be found on MEPS HC-131 (MEPS Employment Variables 2000-2013). The fully-imputed variables in this file are developed from the constructed Employment variables in the 2014 FY PUF.

Observations for these employment variables with values of -7 (refused), -8 (don’t know) or -9 (not ascertained) were imputed using weighted sequential hot-decking. The imputations were performed separately for each MEPS HC panel across the five survey rounds of the MEPS. First, all missing values of a given variable were imputed for Round 1. If a person remained in the same job in Round 2, and the MEPS questionnaire did not ask for updated job information (i.e., if the variable on the FY PUF was coded as -2), then the value for that variable was pulled forward from Round 1 to Round 2 (including values that had been imputed in Round 1). After pulling values forward from Round 1, any remaining missing values were imputed for Round 2. This process was repeated for Rounds 3-5. For Panel 19, the imputed employment variables use constructed employment variables from Round 1, 2 and 3 data on this file. For Panel 18, Rounds 3, 4, and 5 data from the current file are used as well as data from Rounds 1 and 2 from the 2013 Full-Year Consolidated File. Users who want to combine data on all five rounds for an individual in Panel 18, should use 2013 data for Rounds 1 and 2, from MEPS HC-131, and 2014 data for Rounds 3, 4 and 5, from the current file. (Note that MEPS HC-131 also has Round 3 information for Panel 18, but the 2014 PUF has the most up-to-date version of Round 3 information and is the most consistent with 2014 Round 4 and 5 variables.)

Following imputation, no values of -2, -7, -8, or -9 remain on any variable. Due to skip patterns, the majority of -1s (question was not asked due to skip pattern) remain. For reasons of confidentiality, values of -10 (hourly wage was top-coded at $78.00) also remain and employer size (number of employees in establishment) is top-coded at 500.

Variable Naming

The names of the imputed variables are similar to the names of the corresponding constructed variables in this file. An ‘H’ suffix is added and the resulting name is shortened to 8 characters when necessary (e.g., the imputed version of SELFCM31 is SLFCM31H). The variables CMJHLD31/42/53 differ from this naming convention because they are not imputed (they contain no missing values) but were constructed using information from the Person Round Plan (PRPL) File (MEPS HC-169). CMJHLD31/42/53 may be compared with the constructed Employment variables HELD31X/42X/53X. Both of these sets of variables provide information on the insurance coverage individuals obtain through their current main jobs. However, these variables may differ since they are constructed from two different data files and because the CMJHLD31/42/53 variables capture information on some additional sources of employment-related insurance that were identified in the insurance section of the instrument while the HELD31X/42X/53X variables only contain information on sources of coverage identified in the employment section. In addition the values of CMJHLD31 for Panel 18 observations reflect coverage in Round 3 in the 2014 PRPL file as well as in the 2013 PRPL file. Note that the variables CMJHLD31/42/53 are included on this file because they were used to perform logical edits on the OFFER31H/42H/53H and OFEMP31H/42H/53H variables (edits are described below). The CMJHLD31H/42H/53H variables were used to edit the OFFER31H/42H/53H and OFEMP31H/42H/53H variables (rather than the HELD31X/42X/53X variables) because they were more consistent with the other health insurance variables on the FY PUF for each year.

The following table provides the name of the constructed Employment variables that correspond with each imputed Employment variable.

* Both CMJHLD and HELDX reflect the insurance status at a current main job but are constructed from different sources of data. See the text for a description of possible differences in these variables. CMJHLD is not an imputed version of HELDX.

Imputation Strategy

The first variables to be imputed were the employment status variables (EMPST31H/42H/53H) which identify all persons (EMPST31H/42H/53H = 1 or 2) who should have valid information related to their current main job.

EMPST31H/42H/53H are created from EMPST31/42/53. The EMPST31/42/53 variables have separate response categories for individuals who were “employed during the reference period” and those who were “not employed with no job to return to.” In the imputed variables EMPST31H/42H/53H these responses are collapsed into a single category for analytic purposes.

The resulting three responses are mutually exclusive as follows:
Value	Label
-1	INAPPLICABLE
1	EMPLOYED AT RD#/# INT DATE
2	JOB TO RETURN TO AT RD #/# INT DATE
34	NOT EMPLOYED DURING RD #/#

Respondents with EMPST31H/42H/53H equal to 1 or 2 go through the imputation process. Respondents with EMPST31H/42H/53H equal to -1 or 34 have values of -1 for all remaining imputed employment variables.

The next set of variables to be imputed were the self-employment/wage-earner variables (SLFCM31H/42H/53H) which determine skip patterns for the remaining variables (e.g., self-employed persons are not asked about wages).

Many of the remaining variables were imputed separately for wage-earners and the self-employed for the following reasons: 1) self-employed and wage-earners were asked different sets of questions about their current main jobs; 2) even when variables were asked for both groups, the quality of the imputations was improved by specifying separate sets of class variables tailored to the wage-earner and self-employed populations.

The weighted sequential hot decking process requires class variables to impute missing values. These class variables were identified with regression models in order to identify the predictive quality of a set of variables for each variable to be imputed. The set of possible class variables, includes age, gender, region, educational attainment, industry and occupation code, and the set of variables have been consistently used to impute a given variable across panels.

As mentioned above, self-employed and wage-earners were asked different sets of questions about their current main job. These variables can be categorized into the following sets:

Variables with Valid Data for Wage-Earners but Not for Self-Employed Individuals

Hourly wage (HRWG31H, HRWG42H, HRWG53H)
Paid sick leave (SCPAY31H, SCPAY42H, SCPAY53H)
Paid leave to visit a doctor (PAYDR31H, PAYDR42H, PAYDR53H)
Paid vacation (PYVAC31H, PYVAC42H, PYVAC53H)
Pension plan (RTPLN31H, RTPLN42H, RTPLN53H)
Business has more than one location (MORE31H, MORE42H, MORE53H)
Sector: private-foreign govt/federal government/state-local government (JBORG31H,JBORG42H, JBORG53H)

Variables with Valid Data for Self-Employed Individuals but Not for Wage-Earners

Business was incorporated, a proprietorship, or a partnership (BSNTY31H, BSNTY42H,and BSNTY53H)

Variables with Valid Data for All Workers

Usual hours worked per week (HOUR31H, HOUR42H, HOUR53H)
Number of employees (NMEMP31H, NMEMP42H, NMEMP53H)
- Establishment size for wage-earners
- Business size for self-employed
Union status (UNION31H, UNION42H, UNION53H)
Industry category (INDCT31H, INDCT42H, INDCT53H)
Occupation category (OCCCT31H, OCCCT42H, OCCCT53H)

Variables with Valid Data for All Workers Except for Self-Employed Individuals with No Employees (i.e., persons for whom SLFCM31H/42H/53H = 1 and NMEMP31H/42H/53H = 1 within each round)

Insurance coverage from current main job (CMJHLD31, CMJHLD42, CMJHLD53)
Eligible for insurance offered at current main job (OFFER31H, OFFER42H,OFFER53H)
Insurance offered to anyone at current main job (OFEMP31H, OFEMP42H,OFEMP53H)

Additional Detail on Specific Variables

Hourly Wage (HRWG31H, HRWG42H, HRWG53H)

Valid data for imputed hourly wages is available for all wage-earners (SLFCM31H/42H/53H equal to 2). The values for the imputed hourly wage variables (HRWG31H/42H/53H) reflect the most up-to-date version of hourly wages for the wage-earner in each round. By contrast, the constructed hourly wage variables (HRWG31X/42X/53X) identify the wage reported in the round a current main job is first reported. Information on any wage changes after that round are contained in the variables DIFFWG31/42/53 and NHRWG31/42/53. These variables, as well as HRWG31X/42X/53X are used in the construction of the imputed hourly wage variables.

For reasons of confidentiality, the hourly wage variables are top-coded. Like the constructed hourly wage variables, imputed hourly wages greater than or equal to $78.00 are top-coded to a value of -10.

Union Membership (UNION31H/42H/53H)

In addition to using weighted sequential hot-decking techniques, individuals who were identified as being employed by the military had their union membership status logically edited to 2 (no).

Health Insurance (CMJHLD31, CMJHLD42, CMJHLD53, OFFER31H, OFFER42H, OFFER53H, OFEMP31H, OFEMP42H, OFEMP53H)

This file includes several employment-related health insurance variables, CMJHLD31/42/53, OFFER31H/42H/53H, and OFEMP31H/42H/53H. These variables are valid for wage-earners (SLFCM31H/42H/53H = 2) and self-employed individuals with employees (SLFCM31H/42H/53H = 1 and NMEMP31H/42H/53H > 1).

The variables CMJHLD31/42/53 are constructed from the Person-Round-Plan (PRPL) public use file and indicate whether the person held insurance coverage from his/her current main job at some point during the round. This is primarily defined using the PRPL public use file variable CMJINS which identifies insurance obtained through a current main job, and STATUS1-24, which indicates whether the coverage is in effect during the round.. Since Round 3 crosses two calendar years, CMJHLD31 for Panel 18 respondents indicates that the person held coverage during the portion of Round 3 in either the 2013 or 2014 PRPL public use file for the individual.

The variables OFFER31H/42H/53H indicate whether the person was offered (was eligible for) insurance at their current main job at some point during the round. For records that had a value of -9, valid reported values for OFFER31H/42H/53 were brought forward from a previous round (including imputed values from that round) if the person did not change jobs before any further imputations were performed.

The variables OFEMP31H/42H/53H indicate whether an employer offered health insurance to any employees in the establishment and rely on OFFER31H/42H/53H during their construction.

OFFER31H/42H/53H and the related variable OFEMP31H/42H/53H were logically edited as follows. If a person indicates that they held insurance from their current main job (CMJHLD31/42/53 = 1) then OFFER31H/42H/53H was set equal to 1. For Round 3, OFFER31H/53H was set to 1 if the person held coverage at any point in Round 3 in either calendar year. If a person indicated that they held insurance (CMJHLD31/42/53 = 1) or were offered insurance (OFFER31H/42H/53H = 1) at their current main job, then OFEMP31H/42H/53H, the variable indicating that the employer offered insurance to at least one employee, was set equal to 1.

Number of Employees (NMEMP31H, NMEMP42H, NMEMP53H)

Like the corresponding constructed NUMEMP31/42/53, NMEMP31H/42H/53H indicate the number of employees at the location of the person’s current main job. Due to confidentiality concerns, this variable has been top-coded at 500. Missing value imputation is done using weighted sequential hot-decking techniques. Note that the definition of NMEMP31H/42H/53H, like that for NUMPEMP31/42/53, differs for wage-earners and self-employed individuals. For wage-earners, it represents the size of the worker’s establishment. For self-employed individuals, it represents the size of the self-employed individual’s entire business.

2.5.10 Health Insurance Variables (TRIJA14X-PMEDPY53)

2.5.10.1 Monthly Health Insurance Indicators (TRIJA14X-INSDE14X)

Constructed and edited variables are provided that indicate any coverage in each month of 2014 for the sources of health insurance coverage collected during the MEPS interviews (Panel 18 Rounds 3 through 5 and Panel 19 Rounds 1 through 3). In Rounds 2, 3, 4, and 5, insurance that was in effect at the previous round’s interview date was reviewed with the respondent. Most of the insurance variables have been logically edited to address issues that arose during such reviews in Rounds 2, 3, 4, and 5. One edit to the private insurance variables corrects for a problem concerning covered benefits that occurred when respondents reported a change in any of their private health insurance plan names. Additional edits address issues of missing data on the time period of coverage for both public and private coverage that was either reviewed or initially reported in a given round. Additional edits, described below, were performed on the Medicare and Medicaid or State Children’s Health Insurance Program (SCHIP) variables to assign persons to coverage from these sources. Observations that contain edits assigning persons to Medicare or Medicaid/SCHIP coverage can be identified by comparing the edited and unedited versions of the Medicare and Medicaid/SCHIP variables. Starting October 1, 2001, persons 65 years and older have been able to retain TRICARE coverage in addition to Medicare. Therefore, unlike in earlier MEPS public use files, persons 65 years and older do not have their reported TRICARE coverage (TRIJA14X – TRIDE14X) overturned. TRICARE acts as a supplemental insurance for Medicare, similar to Medigap insurance.

Public sources include Medicare, TRICARE, Medicaid, SCHIP, and other public hospital/physician coverage. State-specific program participation in non-comprehensive coverage (STAJA14 – STADE14) was also identified but is not considered health insurance for the purpose of this survey.

Medicare

Medicare (MCRJA14 – MCRDE14) coverage was edited (MCRJA14X – MCRDE14X) for persons age 65 or over. Within this age group, individuals were assigned Medicare coverage if:

They answered “Yes” to a follow-up question on whether they received Social Security benefits; or
They were covered by Medicaid/SCHIP, other public hospital/physician coverage or Medigap coverage; or
Their spouse was age 65 or over and covered by Medicare; or
They reported TRICARE coverage.

Note that age (AGE##X) is checked for edited Medicare, however date of birth is not considered. Edited Medicare is somewhat imprecise with regard to a person’s 65^th birthday.

Medicaid/SCHIP and Other Public Hospital/Physician Coverage

Questions about other public hospital/physician coverage were asked in an attempt to identify Medicaid or SCHIP recipients who may not have recognized their coverage as such. These questions were asked only if a respondent did not report Medicaid or SCHIP directly. Respondents reporting other public hospital/physician coverage were asked follow-up questions to determine if the coverage was through a specific Medicaid HMO or if it included some other managed care characteristics. Respondents who identified managed care from either path were asked if the recipient paid anything for the coverage and/or if a government source paid for the coverage.

The Medicaid/SCHIP variables (MCDJA14 – MCDDE14) have been edited (MCDJA14X – MCDDE14X) to include persons who paid nothing for their other public hospital/physician insurance when such coverage was through a Medicaid HMO or reported to include some other managed care characteristics.

To assist users in further editing sources of insurance, this file contains variables constructed from the other public hospital/physician series that measure whether:

The respondent reported some type of managed care and paid something for the coverage, Other Public A Insurance (OPAJA14 – OPADE14); and
The respondent did not report any managed care, Other Public B Insurance (OPBJA14 – OPBDE14).

The variables OPAJA14 – OPADE14 and OPBJA14 – OPBDE14 are provided only to assist in editing and should not be used to make separate insurance estimates for these types of insurance categories.

Any Public Insurance in Month

The file also includes summary measures that indicate whether or not a sample person has any public insurance in a month (PUBJA14X – PUBDE14X). Persons identified as covered by public insurance are those reporting coverage under TRICARE, Medicare, Medicaid or SCHIP, or other public hospital/physician programs. Persons covered only by state-specific programs that did not provide comprehensive coverage (STAJA14 – STADE14), for example, the Maryland Kidney Disease Program, were not considered to have public coverage when constructing the variables PUBJA14X – PUBDE14X. Note that further edits may be made to the public insurance variables in later MEPS data releases to address cases where private coverage through a federally-facilitated, state-based or state partnership exchange/marketplace may have been originally reported as public insurance. These potential edits could affect the variables MCAID14X, OTPUBA14, OTPUBB14, and PUB14X.

Private Insurance

Variables identifying private insurance in general (PRIJA14 – PRIDE14) and specific private insurance sources [such as employer/union group insurance (PEGJA14 – PEGDE14); non-group (PNGJA14 – PNGDE14); other group (POGJA14 – POGDE14)]; and private insurance through a federally-facilitated, state-based or state partnership exchange/marketplace (PRXJA14 – PRXDE14) were constructed. Private insurance sources identify coverage in effect at any time during each month of 2014. Separate variables identify covered persons and policyholders (policyholder variables begin with the letter “H”, e.g., HPEJA14 – HPEDE14). These variables indicate coverage or policyholder status within a source and do not distinguish between persons who are covered or are policyholders on one or more than one policy within a given source. In some cases, the policyholder was unable to characterize the source of insurance (PDKJA14 – PDKDE14). Covered persons (but not policyholders) are identified when the policyholder is living outside the RU (POUJA14 – POUDE14). An individual was considered to have private health insurance coverage if, at a minimum, that coverage provided benefits for hospital and physician services (including Medigap coverage). Note, however, that persons covered by private insurance through an exchange/marketplace (PRSTX31/42/53/14 and PRXJA14 – PRXDE14) were considered to have private health coverage if that coverage provided hospital/physician services, but excluded coverage that was explicitly identified as Medigap coverage (EPRS.MSUPINS=1). If a person reported Medigap coverage through the exchange/marketplace, then the source of the insurance purchased was edited to reflect coverage “from a professional association” (EPRS.PURCHTYP=1) or “from a group or association” coverage (EPRS.PRIVINS=1). Further descriptions of the exchange variables are detailed below. Sources of insurance with missing information regarding the type of coverage were assumed to contain hospital/physician coverage. Persons without private hospital/physician insurance were not counted as privately insured. Coverage indicated by these variables may be from any type of job where the employment section insurance variables delivered on this file reflect only coverage through a current main job.

Health insurance through a job or union (PEGJA14 – PEGDE14, PRSJA14 – PRSDE14) was initially asked about in the Employment section of the interview and later confirmed in the Health Insurance section. Respondents also had an opportunity to report employer and union group insurance (PEGJA14 – PEGDE14) for the first time in the Health Insurance Section, but this insurance was not linked to a specific job.

All insurance reported to be through a job classified as self-employed with firm size of 1 (PRSJA14 – PRSDE14) was initially reported in the Employment Section and verified in the Health Insurance section. Unlike the other employment-related variables (PEGJA14 – PEGDE14), self-employed-firm size 1 (PRSJA14 – PRSDE14) health insurance could not be reported in the Health Insurance section for the first time. The variables PRSJA14 – PRSDE14 have been constructed to allow users to determine if the insurance should be considered employment-related.

Private insurance that was not employment-related (POGJA14 – POGDE14, PNGJA14 – PNGDE14, PDKJA14 – PDKDE14, POUJA14 – POUDE14, and PRXJA14-PRXDE14) was reported in the Health Insurance section only.

Beginning in Panel 12 Round 2, the response category “Health Insurance Purchasing Alliance” was removed from HX03 (EPRS.PURCHTYP=4) and HX23 (EPRS.PRIVINS=2) because it was infrequently reported and it was not clear how respondents were using this category.

Beginning in Panel 14 Round 5/Panel 15 Round 3, “High Risk Pool” was added to the list of categories at HX03 (EPRS.PURCHTYP=10) and HX23 (EPRS.PRIVINS=13). Beginning FY 2010, High Risk Pool was included in all Other Group insurance categories.

Beginning in Panel 18 Round 3/Panel 19 Round 1, “Federal/State Exchange” was added to the list of private insurance categories at HX03 (EPRS.PURCHTYP=11) and HX23 (EPRS.PRIVINS=14). Additionally, beginning in Panel 18 Round 3/Panel 19 Round 1, variables EPRS.STEXCH03 and EPRS.STEXCH23 were collected at question HP04A (“Is this coverage through {state exchange name}?”) for respondents reporting insurance from a group, directly from an insurance company or HMO, from an insurance agent or from an “other” unspecified source. Note that the state-specific name for the exchange/marketplace was used when asking this question and was also used on the list of private insurance categories at HX03 and HX23. The variables PRSTX31/42/53/14 have been constructed to include persons less than 65 years old who report private insurance through a federally-facilitated, state-based or state partnership exchange/marketplace at HX03 or HX23, or persons 65 years old or older who report private insurance through a federally-facilitated, state-based or state partnership exchange/marketplace at HX03 or HX23 and not covered by Medicare. In addition, persons who reported a source of insurance at HX23 that was not through an exchange/marketplace (e.g. through a group or directly from an insurance company) but who answered yes to HP04A were also classified as having exchange/marketplace coverage instead of being assigned to the category they originally reported. In addition to reporting coverage through an exchange/marketplace, coverage needed to have been identified as hospital/physician coverage (either as Yes (1) or missing (-7, -8, -9)), but not identified as having Medicare supplemental coverage. Currently, the variables PRSTX31/42/53/14 contain information on private coverage that was reported as obtained through a federally-facilitated, state-based or state partnership marketplace. However, MEPS respondents reporting public coverage were also asked whether the public coverage was obtained through a federal or state marketplace in case respondents were confused about whether the source of coverage was public or private. This approach is consistent with the health insurance questions in the Current Population Survey and the National Health Interview Survey. These variables should be considered unedited since some individuals with public coverage reported as through a marketplace may be edited to private exchange/marketplace coverage in later releases of MEPS data, once additional information on family income is available to aid in data edits. Any further edits of this type will also possibly affect the variables MCAID31/42/53/14X, OTPUBA31/42/53/14, OTPUBB31/42/53/14 and PUB31/42/53/14X.

Any Insurance in Month

The file also includes summary measures that indicate whether or not a person has any insurance in a month (INSJA14X – INSDE14X). Persons identified as insured are those reporting coverage under TRICARE, Medicare, Medicaid, SCHIP, or other public hospital/physician or private hospital/physician insurance (including Medigap plans). A person is considered uninsured if not covered by one of these insurance sources.

Persons covered only by state-specific programs that provide non-comprehensive coverage (STAJA14 – STADE14), for example, the Maryland Kidney Disease Program, and those without hospital/physician benefits (for example, private insurance for dental or vision care only, or for accidents or specific diseases) were not considered to be insured when constructing the variables INSJA14X – INSDE14X.

2.5.10.2 Summary Insurance Coverage Indicators (PRVEV14-INSURC14)

The variables PRVEV14-UNINS14 summarize health insurance coverage for the person in 2014 for the following types of insurance: private (PRVEV14); TRICARE (TRIEV14); Medicaid or SCHIP (MCDEV14); Medicare (MCREV14); other public A (OPAEV14); other public B (OPBEV14). Each variable was constructed based on the values of the corresponding 12 month-by-month health insurance variables described above. A value of 1 indicates that the person was covered for at least one day of at least one month during 2014. A value of 2 indicates that the person was not covered for a given type of insurance for all of 2014. The variable UNINS14 summarizes PRVEV14-OPBEV14. Where PRVEV14-OPBEV14 are all equal to 2, then UNINS14 equals 1; person was uninsured for all of 2014. Otherwise, UNINS14 is set to 2, not uninsured for some portion of 2014. For persons not in scope for the full year these summary variables are based on the period of eligibility.

For user convenience this file contains a constructed variable INSCOV14 that summarizes health insurance coverage for the person in 2014, with the following three values:

1 = ANY PRIVATE (Person had any private insurance coverage [including TRICARE/CHAMPVA] any time during 2014)
2 = PUBLIC ONLY (Person had only public insurance coverage during 2014)
3 = UNINSURED (Person was uninsured during all of 2014)

INSURC14 summarizes health insurance coverage for the person in 2014 using eight categories of insurance separated by age:

1 = ANY PRIVATE (0-64) (Person is between 0 and 64 years old and is covered by private insurance or TRICARE/CHAMPVA in 2014)
2 = PUBLIC ONLY (0-64) (Person is between 0 and 64 years old and is covered by public insurance only (excluding TRICARE/CHAMPVA) in 2014)
3 = UNINSURED (0-64) (Person is between 0 and 64 years old and is uninsured for all of 2014)
4 = EDITED MEDICARE ONLY (65+) (Person is 65 years old or more and is covered by edited Medicare only in 2014)
5 = EDITED MEDICARE & PRIV (65+) (Person is 65 years old or more and is covered by edited Medicare and (private insurance or TRICARE/CHAMPVA) in 2014)
6 = EDITED MEDICARE & OTH PUB ONLY (65+) (Person is 65 years old or more and is covered by edited Medicare and (edited Medicaid/SCHIP, Other Government (type A) or Other Government (type B)) in 2014)
7 = UNINSURED (65+) (Person is 65 years old or more and is uninsured for all of 2014)
8 = NO MEDICARE BUT ANY PUBLIC/PRIVATE (65+) (Person is 65 years old or more and is not covered by Medicare but is covered by private insurance or Medicaid, TRICARE/CHAMPVA, Other Public A, or Other Public B in 2014)

Please note, beginning in 2012, Category 7 was revised to categorize persons who are 65 years or older and uninsured, and Category 8 was added to include persons 65 years or older who do not have Medicare, but are covered by public or private insurance.

Please note that both INSCOV14 and INSURC14 categorize TRICARE as private coverage. All other health insurance indicators included in this data release categorize TRICARE as public coverage. If an analyst wishes to consider TRICARE public coverage, the variable can easily be reconstructed using the PRVEV14 and TRIEV14 variables. Also note that these categories are mutually exclusive, with preference given to private insurance and TRICARE. Persons with both private insurance/TRICARE and public insurance will be coded as “1” for INSCOV14 and INSURC14.

Finally, note that out-of-scope persons are coded “2” (No) for PRVEV14-INSCOV14. For all other health insurance variables in this data release, including INSURC14, out-of-scope persons are coded “-1” (Inapplicable).

2.5.10.3 FY 2014 PUF Managed Care Variables (TRIST31X- PRVHMO14)

In addition to the month-by-month indicators of coverage, there are round-specific health insurance variables indicating coverage by an HMO or managed care plan. Managed care variables have been constructed from information on health insurance coverage at any time in a reference period and the characteristics of the plan. A separate set of managed care variables has been constructed for private insurance, Medicaid/SCHIP, and Medicare coverage. The purpose of these variables is to provide information on managed care participation during the portion of the three rounds (i.e., reference periods) that fall within the same calendar year.

Managed care variables for calendar year 2014 are based on responses to health insurance questions asked during the Round 3, 4, and 5 interviews of Panel 18, and the Round 1, 2, and 3 interviews of Panel 19. Each variable ends in “xy” where x and y denote the interview round for Panel 18 and Panel 19, respectively. The variables ending in “31” and “42” correspond to the first two interviews of each panel in the calendar year. Because Round 3 interviews typically overlap the final months of one year and the beginning months of the next year, the “31” variables for Panel 18 have been restricted to the year 2014 portion of the reference period. Similarly, the Panel 18 Round 5 and Panel 19 Round 3 interviews have been restricted to the year 2014 portion of these reference periods, and the corresponding managed care variables have been given the suffix “14” (as opposed to “53”) to emphasize the restricted time frame.

Construction of the managed care variables is straightforward, but three caveats are appropriate. First, MEPS estimates of the number of persons in HMOs are higher than figures reported by other sources, particularly those based on HMO industry data. The differences stem from the use of household-reported information, which may include respondent error, to determine HMO coverage in MEPS.

Second, the managed care questions are asked about the last plan held by a person through his or her establishment (employer or insurer) even though the person could have had a different plan through the establishment at an earlier point during the interview period. As a result, in instances where a person changed his or her establishment-related insurance, the managed care variables describe the characteristics of the last plan held through the establishment.

Third, the “14” versions of the managed care variables for Panel 19 are developed from Round 3 variables that cover different time frames. The health insurance variable for Round 3 is restricted to the same calendar year as the Round 1 and 2 data. The Round 3 variables describing plan type, on the other hand, overlap the next calendar year. As a consequence, the Round 3 managed care variables may not describe the characteristics of the last plan held in the calendar year if the person changed plans after the first of the year.

The variables PRVHMO31/42/14 indicate coverage by a private HMO in Panel 19 Rounds 1 - 3, and Panel 18 Rounds 3 - 5. The variables MCRPHO31/42/14 indicate coverage by a Medicare managed care plan in Panel 19 Rounds 1 - 3, and Panel 18 Rounds 3 - 5. The variables MCRPD31/42/14 indicate coverage by Medicare prescription drug benefit, also known as Part D, in Panel 19 Rounds 1 - 3, and Panel 18 Rounds 3 - 5. The edited version of the Medicare prescription drug coverage variables (MCRPD31/42/14X) include persons who are covered by both edited Medicare and edited Medicaid. The variables MCDHMO31/42/14 and MCDMC31/42/14 indicate coverage by a Medicaid or SCHIP HMO or managed care plan in Panel 19 Rounds 1 - 3, and Panel 18 Rounds 3 - 5. For Panel 19, the “31” version indicates coverage at any time in Round 1, the “42” version indicates coverage at any time in Round 2, and the “14” version represents coverage at any time during the 2014 portion of Round 3. For Panel 18, the “31” version indicates coverage at any time during the 2014 portion of Round 3, the “42” version indicates coverage at any time in Round 4, and the “14” version represents coverage at any time during Round 5 (because Round 5 ends on 12/31/14).

In the health insurance section of the questionnaire, respondents reporting private health insurance were asked to identify what types of coverage a person had via a checklist. If the respondent selected prescription drug or dental coverage from this checklist, variables were constructed to indicate prescription drug or dental coverage respectively. It should be noted, however, that in some cases respondents may have failed to identify prescription drug or dental coverage that was included as part of a hospital and physician plan.

Beginning in 2013, the HINS HMO constructed variables, PRDRNP13, PMNCNP13, PHMONP13, PRVDRL13, and PRVMNC13 were dropped from this file because their source variables (PROGDR, DRLIST, and VISITPAY) were removed from the interview starting in Panel 17 Round 5 and Panel 18 Round 3. Beginning in 2014, the corresponding “31” and “42” constructed variables were dropped from this file.

TRICARE Plan Variables

Round-specific variables are provided that indicate which TRICARE plan the person was covered by for each round of 2014. These variables indicate whether the person was covered by TRICARE Standard (TRIST31/42/14X), TRICARE Prime (TRIPR31/42/14X), TRICARE Extra (TRIEX31/42/14X), and TRICARE for Life (TRILI31/42/14X). Beginning in Panel 9 Rounds 4 and 5/Panel 10 Rounds 1 through 3, CHAMPVA was added to the list of Tricare Plans collected in the instrument. Therefore, the variables TRICH42/14X were created. The “31” version of this variable was constructed starting in 2006. It should be noted that the TRICARE Plan information was elicited from a pick-list, code-all-that-apply question that asked which type of TRICARE plan the person obtained. It should also be noted that the TRICARE plan question was asked at the RU-level, that is, if any person in the RU reported coverage under TRICARE, a follow-up question was asked to determine which TRICARE plan anyone in the RU was covered by. After indicating the specific TRICARE plan or plans for the RU, a second question was asked to determine who in the RU was covered by TRICARE. In each round, each TRICARE Plan variable has five possible values:

1 The person was covered by the applicable TRICARE plan [Standard, Prime, Extra, For Life, or CHAMPVA].
2 The person was covered by TRICARE, but it was not through that particular plan [Standard, Prime, Extra, For Life, or CHAMPVA].
3 The person was not covered by TRICARE.
-9 The person was covered by TRICARE but the plan type was not ascertained.
-1 The person was out-of-scope.

Medicare Managed Care Plans, Part B, and Prescription Drug Benefit

Persons were assigned Medicare coverage based on their responses to the health insurance questions or through logical editing of the survey data. A small number of persons were edited to have Medicare. For this group, coverage through a managed care plan, Part B, and coverage by prescription drug plan questions were not asked. Since no Medicare establishment-person pair exists for this group, the persons’ Medicare managed care, Part B, and prescription drug benefit statuses are set to not ascertained. For those persons who reported Medicare coverage based on their responses to the health insurance questions, the Medicare managed care plan, Part B, and prescription drug benefit questions were asked. Medicare managed care plan and prescription drug benefit questions were asked for each round a person indicates Medicare coverage. Medicare Part B questions were asked during the first report of Medicare only. The Medicare Part B indicator for those persons who indicated not having a Medicare card available was introduced for Panel 14 Round 2 and Panel 13 Round 4. For those persons who reported having Medicare coverage in Round 1, but did not have a Medicare card available, Medicare Part B coverage was set to not ascertained (-9).

The Medicare prescription drug benefit variables (MCRPD31/42/14) have been edited (MCRPD31/42/14X) to turn on coverage for all persons who are covered by both edited Medicare and edited Medicaid regardless of the status on their unedited Medicare prescription drug benefit variable.

In each round, the variables MCRPHO31, MCRPHO42, and MCRPHO14 have five possible values:

1 The person was covered by Medicare and covered through a Medicare Managed Care Plan.
2 The person was covered by Medicare but not covered through a Medicare Managed Care Plan.
3 The person was not covered by Medicare.
-9 The person was covered by Medicare but whether the coverage is through a Medicare Managed Care Plan is refused, don’t know, or not ascertained.
-1 The person was out-of-scope.

In each round, the variables MCRPD31(X), MCRPD42(X), and MCRPD14(X) have five possible values:

1 The person was covered by Medicare and covered by prescription drug benefit.
2 The person was covered by Medicare but not covered by prescription drug benefit.
3 The person was not covered by Medicare.
-9 The person was covered by Medicare but prescription drug benefit coverage is refused, don’t know, or not ascertained.
-1 The person was out-of-scope.

In each round, the variables MCRPB31, MCRPB42, and MCRPB14 have five possible values:

1 The person was covered by Medicare and covered by Part B.
2 The person was covered by Medicare but not covered by Part B.
3 The person was not covered by Medicare.
-9 The person was covered by Medicare but Part B is refused, don’t know, or not ascertained.
-1 The person was out-of-scope.

Medicaid/SCHIP Managed Care Plans

Persons were assigned Medicaid or SCHIP coverage based on their responses to the health insurance questions or through logical editing of the survey data. The number of persons who were edited to have Medicaid or SCHIP coverage is small. These persons indicated coverage through an Other Government program that was identified as being in a Medicaid HMO or gatekeeper plan that did not require premium payment from the insured party. By definition, respondents were asked about the managed care characteristics of this insurance coverage.

Medicaid/SCHIP HMOs

If Medicaid/SCHIP or Other Government programs were identified as the source of hospital/physician insurance coverage, the respondent was asked about the characteristics of the plan. The variables MCDHMO31, MCDHMO42, and MCDHMO14 have been set to “Yes” if, in Panel 18, the plan was identified from a list of state names or programs for Medicaid HMOs in the area, or if an affirmative response was provided to the following question:

Under {{Medicaid/{STATE NAME FOR MEDICAID}/the program sponsored by a state or local government agency which provides hospital and physician benefits} (are/is) (READ NAME(S) FROM BELOW) signed up with an HMO, that is a Health Maintenance Organization?

[With an HMO, you must generally receive care from HMO physicians. If another doctor is seen, the expense is not covered unless you were referred by the HMO, or there was a medical emergency.]

Starting in Panel 19 Round 1, the variables have been set to “Yes” solely based on an affirmative response to the question above. In subsequent rounds, for persons who had been previously identified as covered by Medicaid, the respondent was asked whether the name of the person’s insurance plan had changed since the previous interview. An affirmative response triggered the previous set of questions about managed care (name on list of Medicaid HMOs or signed up with an HMO).

In each round, the variables MCDHMO31, MCDHMO42, and MCDHMO14 have five possible values:

1 The person was covered by a Medicaid/SCHIP HMO.
2 The person was covered by Medicaid/SCHIP but the plan was not an HMO.
3 The person was not covered by Medicaid/SCHIP.
-9 The person was covered by Medicaid/SCHIP but the plan type was not ascertained.
-1 The person was out-of-scope.

Medicaid/SCHIP Gatekeeper Plans

If a person did not belong to a Medicaid/SCHIP HMO, a third question was used to determine whether the person was in a gatekeeper plan. The variables MCDMC31, MCDMC42, and MCDMC14 were set to “Yes” if the respondent provided an affirmative response to the following question:

Does {{Medicaid /{STATE NAME FOR MEDICAID}} require (READ NAME(S) BELOW) to sign up with a certain primary care doctor, group of doctors, or with a certain clinic which they must go to for all of their routine care?

Probe: Do not include emergency care or care from a specialist they were referred to.

In each round, the variables MCDMC31, MCDMC42, and MCDMC14 have five possible values:

1 The person was covered by a Medicaid/SCHIP gatekeeper plan.
2 The person was covered by Medicaid/SCHIP, but it was not a gatekeeper plan.
3 The person was not covered by Medicaid/SCHIP.
-9 The person was covered by Medicaid/SCHIP but the plan type was not ascertained.
-1 The person was out-of-scope.

Private Managed Care Plans

Persons with private insurance were identified from their responses to questions in the health insurance section of the MEPS questionnaire. In some cases, persons were assigned private insurance as a result of comments collected during the interview, but data editing was minimal. As a consequence, most persons with private insurance were asked about the characteristics of their plan, and their responses were used to identify HMO and gatekeeper plans.

Private HMOs

Persons with private insurance were classified as being covered by an HMO if they met any of the three following conditions:

The person reported that his or her insurance was purchased directly through an HMO,
The person reporting private insurance coverage identified the type of insurance company as an HMO, or
The person answered “Yes” to the following question:

Now I will ask you a few questions about how (POLICYHOLDER)’s insurance through (ESTABLISHMENT) works for non-emergency care.

We are interested in knowing if (POLICYHOLDER)’s (ESTABLISHMENT) plan is an HMO, that is, a health maintenance organization. With an HMO, you must generally receive care from HMO physicians. For other doctors, the expense is not covered unless you were referred by the HMO or there was a medical emergency. Is (POLICYHOLDER)’s (INSURER NAME) an HMO?

In subsequent rounds, policyholders were asked whether the name of their insurance plan had changed since the previous interview. An affirmative response triggered the detailed question about managed care (i.e., was the insurer an HMO).

Some insured persons have more than one private plan. In these cases, if the policyholder identified any plan as an HMO, the variables PRVHMO31, PRVHMO42, and PRVHMO14 were set to “Yes.” If a person had multiple plans and one or more were identified as not being an HMO and the other(s) had missing plan type information, the person-level variable was set to missing. Additionally, if a person had multiple plans and none were identified as an HMO, the person-level variable was set to “No.” In each round, the variables PRVHMO31, PRVHMO42, and PRVHMO14 have five possible values:

1 The person was covered by a private HMO.
2 The person was covered by private insurance, but it was not an HMO.
3 The person was not covered by private insurance.
-9 The person was covered by private insurance, but the plan type was not ascertained.
-1 The person was out-of-scope.

2.5.10.4 Flexible Spending Accounts (FSAGT31-FSAAMT31)

Beginning in 2011, questions on Flexible Spending Accounts (FSAs) were asked. Respondents in Round 1 or Round 3 were asked if any RU members set aside pre-tax dollars of their own money to pay for out-of-pocket health care expenses. If an RU has an FSA, then FSAGT31 was set to 1 (Yes) and follow-up questions ascertained who has an FSA (HASFSA31) and the amount of the FSA (FSAAMT31). When an RU has an FSA, HASFSA31 is set for each RU member to indicate which RU member has an FSA. FSAAMT31 is asked at the RU level and collects the total amount contributed to all FSAs belonging to an RU. If no RU member has an FSA, then both HASFSA31 and FSAAMT31 are set to -1 (Inapplicable).

2.5.10.5 Unedited Health Insurance Variables (PREVCOVR-INSENDYY)

Duration of Uninsurance

If a person was identified as being without insurance as of January 1^st in the MEPS Round 1 interview, a series of follow-up questions was asked to determine the duration of uninsurance prior to the start of the MEPS survey. Persons who were insured as of the MEPS Round 1 interview, and persons with a date of birth on or after December 31, 2013 or whose age category was less than 1 year old were skipped past this loop of questions. These questions are asked in Round 1 only.

If the person said he/she was covered by insurance in the two years prior to the MEPS Round 1 interview (PREVCOVR), the month, year (COVRMM, COVRYY), and type of coverage (Employer-sponsored (WASESTB), Medicare (WASMCARE), Medicaid/SCHIP (WASMCAID), TRICARE/CHAMPVA (WASCHAMP), VA/Military Care (WASVA), Other public (WASOTGOV, WASAFDC,WASSSI, WASSTAT1-4, WASOTHER) or Private coverage purchased through a group, association or insurance company (WASPRIV)) was ascertained. Note that under the types of coverage, up to 4 state programs (WASSTAT1-4) can be listed as response options, but only the number of programs available in the state in which the RU is located (up to 4) will be displayed. If the state in which the RU is located has fewer than 4 state programs available, the remaining state programs will be -1 (Inapplicable). The only exception is if the response is Refused (-7) or Don’t Know (-8). In that case, WASTAT1-4 are all coded with the same missing value, regardless of the number of plans available in that specific state. Note that this is a code-all-that-apply question, so more than one source of previous insurance can be selected. For persons who were covered by health insurance on January 1^st, it was ascertained if they were ever without health insurance in the previous year (NOINSBEF). The number of weeks/months without health insurance was also ascertained (NOINSTM, NOINUNIT). For persons who reported only non-comprehensive coverage as of January 1^st, a question was asked to determine if they had been covered by more comprehensive coverage that paid for medical and doctors’ bills in the previous two years (MORECOVR). If they were, the most recent month and year of coverage was ascertained (INSENDMM, INSENDYY) as was the type of coverage (see the variable names above).

Note that these variables are unedited and have been taken directly as they were recorded from the raw data. There may be inconsistencies with the health insurance variables released on public use files that indicate that an individual is uninsured in January. Out-of-scope persons in both panels have been set to “Inapplicable” (-1) for PREVCOVR – INSENDYY. All other persons have PREVCOVR – INSENDYY copied directly from the value of the unedited source variable.

Persons whose January 1^st insurance coverage status could not be determined due to their reference period beginning after January 1^st were also asked the follow-up questions described above. In these cases, persons who reported comprehensive coverage were asked if they were ever without insurance. Those who were uninsured were asked to determine the duration of uninsurance prior to the start of their reference period. Those who reported only non-comprehensive coverage were asked if they had been covered by comprehensive coverage that paid for medical and doctors’ bills in the previous two years. Coverage is determined by health insurance status during the whole reference period or the month of January and ignores that these persons were not in the household on January 1^st.

2.5.10.6 Health Insurance Coverage Variables – At Any Time/At Interview Date/At 12-31 Variables (TRICR31X-STPRAT14)

Constructed and edited variables are provided that indicate health insurance coverage at any time in a given round as well as at the MEPS interview dates and on December 31, 2014. Note that for persons who left the RU before the MEPS interview date or before December 31^st, the variables measuring coverage at the interview date or on December 31^st represent coverage at the date the person left the RU. In addition, since Round 5 only covers the time period from the Round 4 interview date up to December 31^st, values for the December 31^st variables are equivalent to those for Round 5 variables for Panel 18 members.

The health insurance variables are constructed for the sources of health insurance coverage collected during the MEPS interviews (Panel 18 Rounds 3 through 5, and Panel 19 Rounds 1 through 3). Note that the Medicare variables on this file as well as the private insurance variables that indicate the particular source of private coverage (rather than any private coverage) only measure coverage at the interview date and on December 31^st. Users should also note that the same general editing rules were followed for the month-by-month health insurance variables released on this public use file (see Section 2.5.10.1 “Monthly Health Insurance Indicators” for details). Editing programs checking for consistencies between these sets of variables were developed in order to provide as much consistency as possible between the round-specific indicators and the month-by-month indicators of insurance.

Public sources include Medicare, TRICARE, Medicaid/SCHIP, and other public hospital/physician coverage. State-specific program participation in non-comprehensive coverage was also identified but is not considered health insurance for the purpose of this survey.

Medicare

Medicare coverage variables (MCARE31, MCARE42, MCARE53 and MCARE14) and the edited versions of these variables (MCARE31X, MCARE42X, MCARE53X and MCARE14X) were constructed similarly to the month-by-month Medicare variables.

Medicaid/SCHIP and Other Public Hospital/Physician Coverage

Medicaid/SCHIP variables (MCAID31, MCAID42, MCAID53, MCAID14) and the edited versions of these variables (MCAID31X, MCAID42X, MCAID53X, MCAID14X, MCDAT31X, MCDAT42X, MCDAT53X, MCDAT14X) were constructed similarly to the month-by-month Medicaid/SCHIP variables.

Other Public A variables (OTPUBA31, OTPUBA42, OTPUBA53, OTPUBA14; and OTPAAT31, OTPAAT42, OTPAAT53, OTPAAT14) were constructed similarly to the month-by-month Other Public variables.

Any Public Insurance

Any public insurance variables (PUB31X, PUB42X, PUB53X, PUB14X, PUBAT31X, PUBAT42X, PUBAT53X, and PUBAT14X) and state-specific programs that provide non-comprehensive coverage variables (STAPR31, STAPR42, STAPR53, STAPR14, STPRAT31, STPRAT42, STPRAT53, and STPRAT14) were constructed similarly to the month-by-month any public insurance and state-specific program variables.

Private Insurance

Variables identifying private insurance in general (PRIV31, PRIV42, PRIV53, PRIV14, PRIVAT31, PRIVAT42, PRIVAT53, PRIVAT14) and specific private insurance sources (such as employer/union group insurance [PRIEU31, PRIEU42, PRIEU53, PRIEU14]; coverage through a job classified as self-employed with firm size of 1 [PRIS31, PRIS42, PRIS53, PRIS14]; non-group coverage [PRING31, PRING42, PRING53, PRING14]; other group coverage [PRIOG31, PRIOG42, PRIOG53, PRIOG14], coverage through an unknown private category [PRIDK31, PRIDK42, PRIDK53, PRIDK14]; coverage from a policyholder living outside the RU [PROUT31, PROUT42, PROUT53, PROUT14], and coverage through a private exchange [PRSTX31, PRSTX42, PRSTX53, PRSTX14]) were constructed similarly to the month-by-month variables in section 2.5.10.1. Variables indicating any private insurance coverage are available for the following time periods: at any time in a given round, at the interview date, and on December 31^st. The variables for the specific sources of private coverage are only available for coverage on the interview dates and on December 31^st.

Any Insurance in Period

Any insurance variables (INS31X, INS42X, INS53X, INS14X, INSAT31X, INSAT42X, INSAT53X, and INSAT14X) and state-specific programs that provide non-comprehensive coverage variables (STAPR31, STAPR42, STAPR53, STAPR14, STPRAT31, STPRAT42, STPRAT53, and STPRAT14) were constructed similarly to the month-by-month any insurance and state-specific program variables.

2.5.10.7 Dental and Prescription Drug Private Insurance Variables (DENTIN31-PMDINS14)

Dental Private Insurance Variables

Round-specific variables (DENTIN31/42/53) are provided that indicate the person was covered by a private health insurance plan that included at least some dental coverage for each round of 2014. It should be noted that the information was elicited from a pick-list, code-all-that-apply, question that asked what type of health insurance a person obtained through an establishment. The list included: hospital and physician benefits including coverage through an HMO, Medigap coverage, vision coverage, dental, and prescription drugs. It is possible that some dental coverage provided by hospital and physician plans was not independently enumerated in this question. Users should also note that persons with missing information on dental benefits for all reported private plans and those who reported that they did not have dental coverage for one or more plans but had missing information on other plans are coded as not having private dental coverage. Persons with reported dental coverage from at least one reported private plan were coded as having private dental coverage.

DENTIN53 reflects coverage for all of Panel 19 Round 3 where the end reference year could extend into 2015. DENTIN31 for Panel 18 Round 3 reflects coverage in 2013 and 2014 since the Round 3 reference period spans both years. A second version of these dental coverage indicators was built to reflect only current year coverage (DNTINS31/14).

Prescription Drug Private Insurance Variables

Round-specific variables (PMEDIN31/42/53) are provided that indicate the person was covered by a private health insurance plan that included at least some prescription drug insurance coverage for each round of 2014. It should be noted that the information was elicited from a pick-list, code-all-that-apply, question that asked what type of health insurance a person obtained through an establishment. The list included: hospital and physician benefits including coverage through an HMO, Medigap coverage, vision coverage, dental, and prescription drugs. It is possible some prescription drug coverage provided by hospital and physician plans was not independently enumerated in this question. Persons with reported prescription drug coverage from at least one reported private plan were coded as having private prescription drug coverage. Users should note that persons with missing information on prescription drug benefits for all reported private plans and those who reported that they did not have prescription drug coverage for one or more plans but had missing information on other plans are coded as not having private prescription drug coverage.

PMEDIN53 reflects coverage for all of Panel 19 Round 3 where the end reference year could extend into 2015. PMEDIN31 for Panel 18 Round 3 reflects coverage in 2013 and 2014 since the Round 3 reference period spans both years. A second version of these prescription drug coverage indicators was built to reflect only current year coverage (PMDINS31/14).

2.5.10.8 Medical Debt Variables (PROBPY42 – PYUNBL42)

Beginning in 2014, questions relating to medical debt were added to the health insurance section. Respondents in Round 2 or Round 4 were asked questions HX81 (HOME.PROBPAY, “In the past 12 months did anyone in the family have problems paying or were unable to pay any medical bills?”), HX82 (HOME.CURFMPAY, “Does anyone in your family currently have any medical bills that are being paid off over time?”), and HX83 (HOME.PYUNABL, “Does anyone in your family currently have any medical bills that you are unable to pay at all?”). Beginning in 2014, the corresponding constructed variables PROBPY42, CRFMPY42, and PYUNBL42 are included in this file. PROBPY42 was set to 1 (Yes) if the respondent indicated that someone in their family had problems paying or were unable to pay any medical bills. Additional questions ascertained if anyone in the family currently had medical bills that were being paid off over time (CRFMPY42), and if anyone in the family currently had any medical bills that were unable to be paid at all (PYUNBL42). If the respondent indicated that someone in their family currently has any medical bills that are being paid off over time, then CRFMPY42 was set to 1 (Yes). Note that if the respondent indicates that no one in their family had problems paying medical bills, then PYUNBL42 is set to -1 (Inapplicable).

2.5.10.9 Prescription Drug Usual Third Party Payer Variables (PMEDUP31-PMEDPY53)

Round-specific variables are provided that indicate whether the sample member had a usual third party payer for prescription medications (PMEDUP31, PMEDUP42, PMEDUP53), and if so, what type of payer (PMEDPY31, PMEDPY42, PMEDPY53). These questions were asked only of sample members who reportedly had at least one prescription medication purchase in the round. In each interview, if the sample member reportedly had a third party payer, then the respondent was asked the name of the sample member’s usual third party payer. These responses were coded into the following source of payment categories in PMEDPY31, PMEDPY42, PMEDPY53: Private Insurance, Medicare, Medicaid, VA/CHAMPVA, Tricare, State/Local Government, and Other. Users should note that these questions were asked in the Charge and Payment (CP) section of the questionnaire, and that no attempt was made to reconcile the responses with information collected in the health insurance section of the questionnaire.

Starting in FY14, the variables collecting how much the sample member paid out of pocket for his or her last prescription obtained in the round (PMEDPP31, PMEDPP42) are no longer constructed.

2.5.11 Utilization, Expenditures, and Sources of Payment Variables (TOTTCH14-RXOSR14)

The MEPS Household Component (HC) collects data in each round on use and expenditures for office- and hospital-based care, home health care, dental services, vision aids, and prescribed medicines. Data were collected for each sample person at the event level (e.g., doctor visit, hospital stay) and summed across Rounds 3 - 5 for Panel 18 (excluding 2013 events covered in Round 3) and across Rounds 1 - 3 for Panel 19 (excluding 2015 events covered in Round 3) to produce the annual utilization and expenditure data for 2014. In addition, the MEPS Medical Provider Component (MPC) is a follow-back survey that collected data from a sample of medical providers and pharmacies that were used by sample persons in 2014. Expenditure data collected in the MPC are generally regarded as more accurate than information collected in the HC and were used to improve the overall quality of MEPS expenditure data in this file (see below for description of methodology used to develop expenditure data).

This file contains utilization and expenditure variables for several categories of health care services. In general, there is one utilization variable (based on HC responses only), 13 expenditure variables (derived from both HC and MPC responses), and one charge variable for each category of health care service. The utilization variable is typically a count of the number of medical events reported for the category. The 13 expenditure variables consist of an aggregate total payments variable, 10 main component source of payment category variables, and two additional source of payment category variables (see below for description of source of payment categories). Expenditure variables for all categories of health care combined are also provided. These variables generally represent a full year of use and expenditures. However, for persons who were not inscope for the entire year, these variables reflect only the period of eligibility.

The table in Appendix 1 provides an overview of the utilization and expenditure variables included in this file. For each health service category, the table lists the corresponding utilization variable(s) and provides a general key to the expenditure variable names (13 per service category). The first three characters of the expenditure variable names reflect the service category (except only two characters for prescription medicines) while the subsequent three characters (*** in table) reflect the naming convention for the source of payment categories described below (except only two characters for Veterans Administration). The last two positions of all utilization and expenditure variable names reflect the survey year (i.e., 13). More details are provided on the utilization and expenditure variables in sections 2.5.11.1 and 2.5.11.2 below.

2.5.11.1 Expenditures Definition

Expenditures on this file refer to what is paid for health care services. More specifically, expenditures in MEPS are defined as the sum of direct payments for care provided during the year, including out-of-pocket payments and payments by private insurance, Medicaid, Medicare, and other sources. Payments for over-the-counter drugs are not collected in MEPS. Indirect payments not related to specific medical events, such as Medicaid Disproportionate Share and Medicare Direct Medical Education subsidies, are also not included.

The definition of expenditures used in MEPS is somewhat different from the 1987 NMES and 1977 NMCES surveys where charges rather than sum of payments were used to measure expenditures. This change was adopted because charges became a less appropriate proxy for medical expenditures during the 1990s due to the increasingly common practice of discounting charges. Another change from the two prior surveys is that charges associated with uncollected liability, bad debt, and charitable care (unless provided by a public clinic or hospital) are not counted as expenditures because there are no payments associated with those classifications.

While the concept of expenditures in MEPS has been operationalized as payments for health care services, variables reflecting charges for services received are also provided on the file (see below). Analysts should use caution when working with the charge variables because they do not typically represent actual dollars exchanged for services or the resource costs of those services.

Data Sources on Expenditures

The expenditure data included on this file were derived from the MEPS Household and Medical Provider Components. Only HC data were collected for non-physician visits, dental and vision services, other medical equipment and services, and home health care not provided by an agency while data on expenditures for care provided by home health agencies were only collected in the MPC. In addition to HC data, MPC data were collected for a sample of office-based visits to physicians (or medical providers supervised by physicians), hospital-based events (e.g., inpatient stays, emergency room visits, and outpatient department visits), and prescribed medicines. For these types of events, MPC data were used if complete; otherwise, HC data were used if complete. Missing data for events where HC data were not complete and MPC data were not collected or complete were derived through an imputation process (see below).

A series of logical edits were applied to both the HC and MPC data to correct for several problems including, but not limited to, outliers, copayments or charges reported as total payments, and reimbursed amounts that were reported as out-of-pocket payments. In addition, edits were implemented to correct for misclassifications between Medicare and Medicaid and between Medicare HMOs and private HMOs as payment sources. Data were not edited to insure complete consistency between the health insurance and source of payment variables on the file.

Imputation for Missing Expenditures and Data Adjustments

Expenditure data were imputed to 1) replace missing data, 2) provide estimates for care delivered under capitated reimbursement arrangements, and 3) to adjust household-reported insurance payments because respondents were often unaware that their insurer paid a discounted amount to the provider. This section contains a general description of the approaches used for these three situations. A more detailed description of the editing and imputation procedures is provided in the documentation for the MEPS event-level files.

The predictive mean matching imputation method was used to impute missing expenditures. This procedure uses regression models (based on events with completely reported expenditure data) to predict total expenses for each event. Then, for each event with missing payment information, a donor event with the closest predicted payment with the same pattern of expected payment sources as the event with missing payment was used to impute the missing payment value.

The general approach that was used to impute missing expenditure data on prescribed medicines is described in section 2.5.11.2 below.

Because payments for medical care provided under capitated reimbursement arrangements and through public clinics and Veterans’ Hospitals are not tied to particular medical events, expenditures for events covered under those types of arrangements and settings were also imputed. Using a weighted sequential hot-deck procedure, events covered under capitated arrangements were imputed from events covered under managed care arrangements that were paid based on a discounted fee-for-service method, while imputations for visits to public clinics and Veterans’ Hospitals were based on similar events that were paid on a fee-for-service basis. As for other events, selected predictor variables were used to form groups of donor and recipient events for the imputations.

An adjustment was also applied to some HC-reported expenditure data because an evaluation of matched HC/MPC data showed that respondents who reported that charges and payments were equal were often unaware that insurance payments for the care had been based on a discounted charge. To compensate for this systematic reporting error, a weighted sequential hot-deck imputation procedure was implemented to determine an adjustment factor for HC-reported insurance payments when charges and payments were reported to be equal. As for the other imputations, selected predictor variables were used to form groups of donor and recipient events for the imputation process.

Methodology for Flat Fee Expenditures

Most of the expenditures for medical care reported by MEPS participants are associated with single medical events. However, in some situations there is one charge that covers multiple contacts between a medical provider and patient (e.g., obstetrician services, orthodontia). In these situations (generally called flat or global fees), total payments for the flat or global fee were included if the initial service was provided in 2014. For example, all payments for an orthodontist’s fee that covered multiple visits over three years were included if the initial visit occurred in 2014. However, if a visit in 2014 to an orthodontist was part of a flat fee in which the initial visit occurred in 2013, then none of the payments for the flat fee were included.

The approach used to count expenditures for flat fees may create what appear to be inconsistencies between utilization and expenditure variables. For example, if several visits under a flat fee arrangement occurred in 2014 but the first visit occurred in 2013, then none of the expenditures were included, resulting in low expenditures relative to utilization for that person. Conversely, the flat fee methodology may result in high expenditures for some persons relative to their utilization. For example, all of the expenditures for an expensive flat fee were included even if only the first visit covered by the fee had occurred in 2014. On average, the methodology used for flat fees should result in a balance between overestimation and underestimation of expenditures in a particular year.

Zero Expenditures

There are some medical events reported by respondents where the payments were zero. This could occur for several reasons including (1) free care was provided, (2) bad debt was incurred, (3) care was covered under a flat fee arrangement and it was not the initial event of the bundle (see prior section on Methodology for Flat Fee Expenditures), or (4) follow-up visits were provided without a separate charge (e.g., after a surgical procedure). In summary, these types of events have no impact on totals for the person-level expenditure variables contained in this file.

Source of Payment Categories

In addition to total expenditures, variables are provided that itemize expenditures according to the major source of payment categories. These categories are:

Out of pocket by patient or patient’s family (SLF);
Medicare (MCR);
Medicaid (MCD);
Private Insurance (PRV);
Veterans’ Administration/CHAMPVA, excluding TRICARE (VA);
TRICARE (TRI);
Other Federal Sources--includes Indian Health Service, military treatment facilities, and other care provided by the federal government (OFD);
Other State and Local Source--includes community and neighborhood clinics, state and local health departments, and state programs other than Medicaid (STL);
Worker’s Compensation (WCP);
Other Unclassified Sources--includes sources such as automobile, homeowner’s, liability, and other miscellaneous or unknown sources (OSR).

Two additional source of payment variables were created to classify payments for particular persons that appear inconsistent due to differences between the survey questions on health insurance coverage and sources of payment for medical events. These variables include:

Other Private (OPR) - any type of private insurance payments reported for persons not reported to have any private health insurance coverage during the year as defined in MEPS (i.e., for hospital and physician services); and
Other Public (OPU) - Medicaid payments reported for persons who were not reported to be enrolled in the Medicaid program at any time during the year.

Though relatively small in magnitude, users should exercise caution when interpreting the expenditures associated with the OPR and OPU categories. While these payments stem from apparent inconsistent responses to the health insurance and source of payment questions in the survey, some of these inconsistencies may have logical explanations. For example, private insurance coverage in MEPS is defined as having a major medical plan covering hospital and physician services. If a MEPS sample person did not have such coverage but had a single service type insurance plan (e.g., dental insurance) that paid for a particular episode of care, those payments may be classified as “other private.” Some of the “other public” payments may stem from confusion between Medicaid and other state and local programs or may be for persons who were not enrolled in Medicaid, but were presumed eligible by a provider who ultimately received payments from the program.

The naming conventions used for the source of payment expenditure variables are shown in parentheses in the list of categories above and in the key to the attached table in Appendix 1. In addition, total expenditure variables (EXP in key) based on the sum of the 12 source of payment variables above are provided.

Charge Variables

In addition to the expenditure variables described above, a variable reflecting total charges is provided for each type of service category (except prescribed medicines). This variable represents the sum of all fully established charges for care received and usually does not reflect actual payments made for services, which can be substantially lower due to factors such as negotiated discounts, bad debt, and free care (see above). The weighted sequential hot-deck procedure was used to impute the missing total charges. The naming convention used for the charge variables (TCH) is also included in the key to the attached table in Appendix 1. The total charge variable across services (TOTTCH14) excludes prescribed medicines.

2.5.11.2 Utilization and Expenditure Variables by Type of Medical Service

The following sections summarize definitional, conceptual, and analytic considerations when using the utilization and expenditure variables in this file. Separate discussions are provided for each MEPS medical service category. There is also a discussion in the section dealing with analyses of trends using MEPS data (section 3.11).

Medical Provider Visits (i.e., Office-Based Visits)

Medical provider visits consist of encounters that took place primarily in office-based settings and clinics. Care provided in other settings such as a hospital, nursing home, or a person’s home are not included in this category.

The total number of office-based visits reported for 2014 (OBTOTV14) as well as the number of such visits to physicians (OBDRV14) and non-physician providers (OBOTHV14) are contained in this file. For a small proportion of sample persons, the sum of the physician and non-physician visit variables (OBDRV14+OBOTHV14) is less than the total number of office-based visits variable (OBTOTV14) because OBTOTV14 contains visits where it was not reported in the HC whether a physician or non-physician provider was seen. Non-physician visits (OBOTHV14) include visits to the following types of providers: chiropractors, midwives, nurses and nurse practitioners, optometrists, podiatrists, physician’s assistants, physical therapists, occupational therapists, psychologists, social workers, technicians, receptionists/clerks/secretaries, or other medical providers. Separate utilization variables are included for selected types of more commonly seen non-physician providers including chiropractors (OBCHIR14), nurses/nurse practitioners (OBNURS14), optometrists (OBOPTO14), physician assistants (OBASST14), and physical or occupational therapists (OBTHER14).

Expenditure variables associated with all medical provider visits, physician visits, and non-physician visits in office-based settings can be identified using the attached table in Appendix 1. As for the corresponding utilization variables, the sum of the physician and non-physician visit expenditure variables (e.g. OBDEXP14+OBOEXP14) is less than the total office-based expenditure variable (OBVEXP14) for a small proportion of sample persons. This can occur because OBVEXP14 includes visits where it was not reported whether a physician or non-physician provider was seen.

Hospital Events

Separate utilization variables for hospital care are provided for each type of setting (outpatient department, emergency room, and inpatient stays) along with three expense variables per setting: one for basic hospital facility expenses, one for payments to physicians who billed separately for services provided at the hospital (referred to as “separately billing doctor” or SBD expenses) and one that aggregates the facility and SBD expenses (aggregated variable not included in files prior to 2007).

Hospital facility expenses include all expenses for direct hospital care, including room and board, diagnostic and laboratory work, x-rays, and similar charges, as well as any physician services included in the hospital charge. SBD expenses typically cover services provided to patients in hospital settings by providers like radiologists, anesthesiologists, and pathologists, whose charges are often not included in hospital bills.

Hospital Outpatient Visits

Variables for the total number of reported visits to hospital outpatient departments in 2014 (OPTOTV14) as well as the number of outpatient department visits to physicians (OPDRV14) and non-physician providers (OPOTHV14) are contained in this file. For a small proportion of sample persons, the sum of the physician and non-physician visit variables (OPDRV14 + OPOTHV14) is less than the total number of outpatient visits variable (OPTOTV14) because OPTOTV14 contains visits where it was not reported whether a physician or non-physician provider was seen.

Expenditure variables (both facility and SBD) associated with all medical provider visits, physician visits, and non-physician visits in outpatient departments can be identified using the attached table in Appendix 1. As for the corresponding utilization variables, the sum of the physician and non-physician expenditure variables (e.g., OPVEXP14 + OPOEXP14 for facility expenses) is less than the variable for total outpatient department expenditures (e.g., OPFEXP14 for facility expenses) for a small proportion of sample persons. This can occur because OBFEXP14 includes visits where it was not reported whether a physician or non-physician provider was seen. No expenditure variables are provided for health care consultations that occurred over the telephone.

Medical Provider (Office) and Hospital Outpatient Combined Visits

Medical provider and hospital outpatient combined visits for Chiropractor (AMCHIR14), Ambulatory Nurse/Practitioner (AMNURS14), Ambulatory Optometrist (AMOPTO14), Physician Assistant (AMASST14) and Ambulatory PT/OT Therapy (AMTHER14) are also contained in this file.

Expenditure variables (both facility and SBD) associated with medical provider plus hospital outpatient visits can be identified using attached table in Appendix 1.

Hospital Emergency Room Visits

The variable ERTOT14 represents a count of all emergency room visits reported for the survey year. Expenditure variables associated with ERTOT14 are identified in the attached table in Appendix 1. It should be noted that hospitals usually include expenses associated with emergency room visits that immediately result in an inpatient stay with the charges and payments for the inpatient stay. Therefore, to avoid the potential for double counting when imputing missing expenses, separately reported facility expenditures for emergency room visits that were identified in the MPC as directly linked to an inpatient stay were included as part of the inpatient stay only (see section on Hospital Inpatient Stays below). This strategy to avoid double counting resulted in $0 facility expenditures for these emergency room visits (but there still may be associated SBD expenses). However, these $0 emergency room visits are still counted as separate visits in the utilization variable ERTOT14.

Hospital Inpatient Stays

Two measures of total inpatient utilization are provided on the file:

IPDIS14 is the total number of hospital discharges. It includes hospital stays where the dates of admission and discharge were reported as identical. These “zero-night stays” can be included or excluded from inpatient analyses at the user’s discretion (see last paragraph of this section).
IPNGTD14 is the total number of nights associated with these discharges. Please note that the variable IPNGTD14 is an imputed version of the IPNGT14 variable released earlier on HC-165. For the 41 cases that were missing length of stay information, data were imputed using a median imputation method.

Expenditure variables associated with hospital inpatient stays are identified in the attached table in Appendix 1. As described in the previous section, payments associated with emergency room visits that immediately preceded an inpatient stay are included with the inpatient expenditures. In addition, payments associated with healthy newborns are included with expenditures for the mother (see next paragraph for more detail).

Data used to construct the inpatient utilization and expenditure variables for newborns were edited to exclude stays where the newborn left the hospital on the same day as the mother. This edit was applied because discharges for infants without complications after birth were not consistently reported in the survey, and charges for newborns without complications are typically included in the mother’s hospital bill. However, if the newborn was discharged at a later date than the mother was discharged, then the discharge was considered a separate stay for the newborn when constructing the utilization and expenditure variables.

Some analysts may prefer to exclude “zero-night stays” from inpatient analyses and/or count these stays as ambulatory visits. Therefore, a separate variable is provided that contains a count of the number of inpatient events where the reported dates of admission and discharge were the same (IPZERO14). This variable can be subtracted from IPDIS14 to exclude “zero-night stays” from inpatient utilization estimates. In addition, separate expenditure variables are provided for zero-night facility expenses (ZIFEXP14) and for separately billing doctor expenses (ZIDEXP14). Analysts who choose to exclude zero-night stays from inpatient expenditure analyses need to subtract the zero-night expenditure variable from the corresponding expenditure variable for total inpatient stays (e.g., IPFEXP14-ZIFEXP14 for facility expenses, IPDEXP14-ZIDEXP14 for separately billing doctor expenses).

Dental Care Visits

The total number of dental care visits variable (DVTOT14) includes those to any person(s) for dental care including general dentists, dental hygienists, dental technicians, dental surgeons, orthodontists, endodontists, and periodontists. Additional variables are provided for the numbers of dental visits to general dentists (DVGEN14) and to orthodontists (DVORTH14). For a small proportion of sample persons, the sum of the general dentist and orthodontist visit variables (DVGEN14+DVORTH14) may not be equal to the total number of dental visits (DVTOT14). This result can only occur for persons who were reported to have seen both a general dentist and orthodontist in the same visit(s). When this occurred, expenditures for the visit were included as orthodontist expenses (DVOEXP14) but not as general dentist expenses (DVGEXP14). Expenditures for dental visits where it was not reported that a general dentist or orthodontist was seen are only included in the total dental expenses variable (DVTEXP14). Expenditure variables for all three categories of dental providers can be identified using the attached table in Appendix 1.

Home Health Care

In contrast to other types of medical events where data were collected on a per visit basis, information on home health care utilization is collected in MEPS on a per month basis. Variables are provided that indicate the total number of days in 2014 where home health care was received from the following: from any type of paid or unpaid caregiver (HHTOTD14), from agencies, hospitals, or nursing homes (HHAGD14), from self-employed persons (HHINDD14), and from unpaid informal caregivers not living with the sample person (HHINFD14). The number of provider days represents the sum across months of the number of days on which home health care was received, with days summed across all providers seen. For example, if a person received care in one month from one provider on two different days, then the number of provider days would equal two. The number of provider days would also equal two if a person received care from two different providers on the same day. However, if a person received care from one provider two times on the same day, then the provider days would equal one. These variables were assigned missing values if the number of provider days could not be computed for any month in which the specific type of home health care was received.

Separate expenditure variables are provided for agency-sponsored home health care (includes care provided by home health agencies, hospitals, and nursing homes) and care provided by self-employed persons. The attached table in Appendix 1 identifies the home health care utilization and expenditure variables contained in the file.

Vision Aids

Expenditure variables for the purchase of glasses and/or contact lenses are identified in the attached table in Appendix 1. Due to the data collection methodology, it was not possible to determine whether vision items that were reported in Round 3 had been purchased in 2013 or 2014. Therefore, expenses reported in Round 3 were only included if more than half of the person’s reference period for the round was in 2014.

Other Medical Equipment and Services

This category includes expenditures for ambulance services, orthopedic items, hearing devices, prostheses, bathroom aids, medical equipment, disposable supplies, alterations/modifications, and other miscellaneous items or services that were obtained, purchased, or rented during the year. On this file, diabetic supplies and insulin are not considered to be medical equipment. All use and expenditure information for these items are included in the prescribed medicine variables. Respondents were asked only once (in Round 3) about their total annual expenditures and were not asked about their frequency of use of these services. Expenditure variables representing the combined expenses for these supplies and services are identified in the Appendix 1 table.

Prescribed Medicines

There is one total utilization variable (RXTOT14) and 13 expenditure variables included on the 2014 full-year file relating to prescribed medicines. These 13 expenditure variables include an annual total expenditure variable (RXEXP14) and 12 corresponding annual source of payment variables (RXSLF14, RXMCR14, RXMCD14, RXPRV14, RXVA14, RXTRI14, RXOFD14, RXSTL14, RXWCP14, RXOSR14, RXOPR14, and RXOPU14). The total utilization variable is a count of all prescribed medications purchased during 2014 (includes initial purchases and refills). The total expenditure variable sums all amounts paid out-of-pocket and by third party payers for each prescription purchased in 2014. No variables reflecting charges for prescription medicines are included because a large proportion of respondents to the MEPS pharmacy component survey did not provide charge data (see below).

Prescribed Medicines Data Collected

Data regarding prescription drugs were obtained through the household questionnaire and a pharmacy component survey. During each round of the MEPS-HC, all respondents were asked to supply the name of any prescribed medication they or their family members purchased or otherwise obtained during that round. For each medication and in each round, the following information was collected: whether any free samples of the medication were received; the name(s) of any health conditions the medication was prescribed for; the number of times the prescription drug was obtained or purchased; the year, month, and day on which the person first used the medication; and a list of the names, addresses, and types of pharmacies that filled the household’s prescriptions. Also, during the Household Component, respondents were asked if they send in claim forms for their prescriptions (self-filers) or if their pharmacy providers do this automatically for them at the point of purchase (non-self-filers). For non-self-filers, charge and payment information was collected in the pharmacy component survey, unless the purchase was an insulin or diabetic supply/equipment event. However, charge and payment information was collected for self-filers in the household questionnaire, because payments by private third party payers for self-filers’ purchases would not be available from the pharmacy component. Uninsured persons were treated as those whose pharmacies filed their prescription claims at the point of purchase. Persons who said they did not know if they sent in their own prescription claim forms were treated as those who did send in their own prescription claim forms.

Pharmacy providers identified by the household were contacted by telephone in the pharmacy component if permission to release their pharmacy records was obtained in writing from the person with the prescription. The signed permission forms were provided to the various establishments prior to making any requests for information. Each establishment was informed of all persons participating in the survey that had prescriptions filled there in 2014 and a computerized printout containing information about these prescriptions was sought. For each medication listed, the following information was requested: date filled, national drug code (NDC), medication name, strength of medicine (amount and unit), quantity (package size and amount dispensed), and payments by source.

When diabetic supplies, such as syringes and insulin, were reported in the other medical supply section of the MEPS-HC questionnaire as having been obtained during the round, the interviewer was directed to collect information on these items in the prescription drug section of MEPS. Charge and payment information was asked for these events.

Prescribed Medicines Data Editing and Imputation

The general approach to preparing the household prescription data for this file was to utilize the pharmacy component prescription data to assign expenditure values to the household drug mentions. For events for which charge and payment data were collected from the household in the HC, information on payment sources was retained to the extent that these data were reported. For those with Pharmacy Component data, a matching program was adopted to link pharmacy component drugs and the corresponding drug information to household drug mentions. To improve the quality of these matches, all drugs on the household and pharmacy files were coded based on the medication names provided by the household and pharmacy, and when available, the national drug code (NDC) provided in the pharmacy survey. Considerable editing was done prior to the matching to correct data inconsistencies in both data sets, fill in missing data, and correct outliers on the pharmacy file.

Drug price per unit outliers were analyzed on the pharmacy file by first identifying the average wholesale unit price (AWUP) of the drug by linkage through the NDC to a proprietary database. In general, prescription drug unit prices were deemed to be outliers by comparing unit prices reported in the pharmacy database to the AWUP and were edited, as necessary. Beginning with the 2007 data, the rules used to identify outlier prices for prescription medications in the PC changed. New outlier thresholds were established based on the distribution of the ratio of retail unit prices relative to the AWUP in the 2007 MarketScan Outpatient Pharmaceutical Claims database.

Starting with the 2008 Prescribed Medicine file, improvements in the data editing changed the distribution of payments by source: (1) more spending on Medicare beneficiaries is by private insurance, rather than Medicare, and (2) there are less out-of-pocket payments and more Medicaid payments among Medicaid enrollees. Beginning with the 2009 data, another change affected the data for Medicare beneficiaries with both Part D and Medicaid coverage: reported Medicaid and other state and local program payments were no longer edited to be Medicare payments.

For Round 3, which spans two years, drug mentions in that round were allocated between the years based on the number of times the respondent said the drug was purchased in the respective year, the year the person started taking the drug, the length of the person’s round, the dates of the person’s round, and the number of fills of that drug for that person in the round.

Collapsed Source of Payment Variables

Two additional source of payment variables are included for each health care service category as a convenience to data users since they are common analytic groupings of the payment sources. The first (***PTR14 series) is the sum of the private and Tricare payer categories (i.e., ***PTR14=***PRV14+***TRI14). The second (***OTH14 series) is the sum of the least common source of payment categories including: 1) other federal (***OFD14), 2) state and local (***STL14), 3) other private (***OPR14), 4) other public (***OPU14), and 5) other sources (***OSR14). Since the ***PTR14 and ***OTH14 variable series represent combined totals of existing individual source of payment variables, analysts should exercise caution to avoid inappropriate double counting of expenditures when working with these variables.

3.0 Survey Sample Information

3.1 Background on Sample Design and Response Rates

The MEPS is designed to produce estimates at the national and regional level over time for the civilian, noninstitutionalized population of the United States and some subpopulations of interest. The data in this public use file pertain to calendar year 2014. The data were collected in Rounds 1, 2, and 3 for MEPS Panel 19 and Rounds 3, 4, and 5 for MEPS Panel 18. (Note that Round 3 for a MEPS panel is designed to overlap two calendar years, as illustrated below.)

This image illustrates that 2014 data was collected in Rounds 3, 4, and 5 of Panel 18, and Rounds 1, 2, and 3 of Panel 19.

Variables convey the same information for this full year consolidated file that has been provided for the full year consolidated files associated with years 1996 – 2013 of MEPS.

The only utilization data that appear on this file are those associated with health care events reported by MEPS respondents and occurring in calendar year 2014. These data were obtained from both MEPS panels for those rounds (or portions of rounds) associated with 2014.

A sample design feature shared by both Panel 18 and Panel 19 involved the partitioning of the sample domain “Other” (serving as the catchall stratum, and consisting mainly of households with “White” members) into two sample domains. This was done for the first time in Panel 16. The two domains were defined as: those households characterized as “complete” respondents to the NHIS; and those characterized as “partial completes.” NHIS “partial completes” typically have a lower response rate to MEPS and for both MEPS panels the “partial” domain was sampled at a lower rate than the “complete” domain. This approach served to reduce survey costs, since the “partials” tend to have higher costs in gaining survey participation, but increased sample variability due to the resulting increased variance in sampling rates.

3.1.2 MEPS--Linked to the National Health Interview Survey (NHIS)

Each responding household found in this 2014 MEPS database is associated with one of two separate and overlapping MEPS panels, MEPS Panel 18 and MEPS Panel 19. These panels consist of subsamples of households participating in the 2012 and 2013 NHIS, respectively, and reflecting the NHIS sample design first implemented in 2006.

Whenever there is a change in sample or study design, it is good survey practice to assess whether such a change could affect the sample estimates. For example, increased coverage of the target populations with an updated sample design based on data from the latest Census can improve the accuracy of the sample estimates. MEPS estimates have been and will continue to be evaluated to determine if an important change in the survey estimates might be associated with a change in design.

As background, the NHIS is a complex multi-stage sample design. A brief and simplified description of the NHIS design follows. The first stage of sample selection is an area sample of PSUs, where PSUs generally consist of one or more counties. Within PSUs, density strata are formed, generally reflecting the density of minority populations for single or groups of blocks or block equivalents that are assigned to the strata. Within each such density stratum “supersegments” are formed, consisting of clusters of housing units. Samples of supersegments are selected for use over a 10-year data collection period for the NHIS. Households within supersegments are selected for each calendar year the NHIS is carried out. In the NHIS sample design used since 2006, Asians are oversampled in addition to Hispanics and Blacks. These features of the NHIS complex survey design carry over to the MEPS. The only major difference in eligibility status for housing units between NHIS and MEPS is that college dorms represent ineligible housing units for MEPS. College aged students living away from home during the school year were interviewed at their place of residence for the NHIS but were identified by and linked to their parents’ household for MEPS. (There is also a person-level stage of sampling for the NHIS, but that does not affect the MEPS sample design.)

The households (occupied DUs) selected for MEPS Panel 18 were a subsample of the 2012 NHIS responding households, while those in MEPS Panel 19 were a subsample of 2013 NHIS responding households. A MEPS household may contain one or more family units, each consisting of one or more individuals. Analysis using MEPS data can be undertaken using either the individual or the family as the unit of analysis.

There were 9,700 households (occupied DUs) selected for MEPS Panel 18, of which 9,685 were eligible for fielding (college dormitories were eliminated). They were randomly selected from among the households responding to the 2012 NHIS. A subsample of 9,700 households was randomly selected for MEPS Panel 19 from the households responding to the 2013 NHIS, of which 9,667 were fielded for MEPS after the elimination of college dorms.

3.1.3 Sample Weights and Variance Estimation

In the database “MEPS HC-171: 2014 Full Year Consolidated Data File,” weight variables are provided for generating MEPS estimates of totals, means, percentages, and rates for persons and families in the civilian noninstitutionalized population. The person-level weight variable PERWT14F provided in this file supersedes the corresponding person-level weight variable provided in the 2014 Full Year Population Characteristic File (HC-165). Procedures and considerations associated with the construction and interpretation of person and family-level estimates using these and other variables are discussed below.

3.2 The MEPS Sampling Process and Response Rates: An Overview

For most MEPS panels, a sample representing about three-eighths of the NHIS responding households is made available for use in MEPS. This was the case for both MEPS Panel 18 and Panel 19.

Because the MEPS subsampling has to be done soon after NHIS responding households are identified, a small percentage of the NHIS households initially characterized as NHIS respondents are later classified as nonrespondents for the purposes of NHIS data analysis. This actually serves to increase the overall MEPS response rate slightly since the percentage of NHIS households designated for use in MEPS (all those characterized initially as respondents from the NHIS panels and quarters used by MEPS for a given year) is slightly larger than the final NHIS household-level response rate and some NHIS nonresponding households do participate in MEPS. However, as a result, these NHIS nonrespondents who are MEPS participants have no NHIS data available to link with MEPS data. Once the MEPS sample is selected from among the NHIS households characterized as NHIS respondents, RUs representing students living in student housing or consisting entirely of military personnel are deleted from the sample. For the NHIS, college students living in student housing are sampled independently from their families. For MEPS, such students are identified through the sample selection of their parents’ RU. Removing from MEPS those college students found in college housing sampled for the NHIS eliminates the opportunity of multiple chances of selection for MEPS for these students. Military personnel not living in the same RU as civilians are ineligible for MEPS. After such exclusions, all RUs associated with households selected from among those identified as NHIS responding households are then fielded in the first round of MEPS.

Table 3.1 shows in Rows A, B, and C the three informational components just discussed. Row A indicates the percentage of NHIS households eligible for MEPS. Row B indicates the number of NHIS households sampled for MEPS. Row C indicates the number of sampled households actually fielded for MEPS (after dropping the students and military members discussed above). Note that all response rates discussed here are unweighted.

3.2.1 Response Rates

In order to produce annual health care estimates for calendar year 2014 based on the full MEPS sample data from the MEPS Panel 18 and Panel 19, the two panels are combined. More specifically, full calendar year 2014 data collected in Rounds 3 through 5 for the MEPS Panel 18 sample are pooled with data from the first three rounds of data collection for the MEPS Panel 19 sample (the general approach is described below).

As mentioned above, all response rates discussed here are unweighted. To understand the calculation of MEPS response rates, some features related to MEPS data collection should be noted. When an RU is visited for a round of data collection, changes in RU membership are identified. Such changes include the formation of student RUs as well as other new RUs created when RU members from a previous round have moved to another location in the U.S. Thus, the number of RUs eligible for MEPS interviewing in a given round is determined after data collection is fully completed. The ratio of the number of RUs completing the MEPS interview in a given round to the number of RUs characterized as eligible to complete the interview for that round represents the “conditional” response rate for that round expressed as a proportion. It is “conditional” in that it pertains to the set of RUs characterized as eligible for MEPS for that round and thus is “conditioned” on prior participation rather than representing the overall response rate through that round. For example, in Table 3.1, for Panel 18, Round 2 the ratio of 7,402 (Row G) to 7,971 (Row F) multiplied by 100 represents the response rate for the round (92.9 percent when computed), conditioned on the set of RUs characterized as eligible for MEPS for that round. Taking the product of the percentage of the NHIS sample eligible for MEPS (Row A) with the product of the ratios for a consecutive set of MEPS rounds beginning with Round 1 produces the overall response rate through the last MEPS round specified.

The overall unweighted response rate for the combined sample of Panel 18 and Panel 19 for 2014 was obtained by computing the products of the relative sample sizes and the corresponding overall panel response rates and then summing the two products. Panel 19 represents about 50.0 percent of the combined sample size while Panel 18 represents the remaining 50.0 percent. Thus, the combined response rate of 48.5 percent was computed as 0.500 times 48.5, the overall Panel 19 response rate through Round 3 plus 0.500 times 48.6, the overall Panel 18 response rate through Round 5.

3.2.2 Panel 19 Response Rates

For MEPS Panel 19, Round 1, 9,667 households were fielded in 2014 (Row C of Table 3.1), a randomly selected subsample of the households responding to the 2013 National Health Interview Survey (NHIS).

Table 3.1 shows the number of RUs eligible for interviewing in each Round of Panel 19 as well as the number of RUs completing the MEPS interview. Computing the individual round “conditional” response rates as described in section 3.2.1 and then taking the product of these three response rates and the factor 76.2 (the percentage of the NHIS sampled households designated for use in selecting a sample of households for MEPS) yields an overall response rate of 48.5 percent for Panel 19 through Round 3.

Return To Table Of Contents

3.2.3 Panel 18 Response Rates

For MEPS Panel 18, 9,685 households were fielded in 2013 (as indicated in Row C of Table 3.1), a randomly selected subsample of the households responding to the 2012 National Health Interview Survey (NHIS).

Table 3.1 shows the number of RUs eligible for interviewing and the number completing the interview for all five rounds of Panel 18. The overall response rate for Panel 18 was computed in a similar fashion to that of Panel 19 but covering all five rounds of MEPS interviewing as well the factor representing the percentage of NHIS sampled households eligible for MEPS. The overall response rate for Panel 18 through Round 5 is 48.6 percent.

Return To Table Of Contents

3.2.4 Annual (Combined Panel) Response Rate

A combined panel response rate for the survey respondents in this data set is obtained by taking a weighted average of the panel specific response rates. The Panel 18 response rate was weighted by a factor of 0.500 and Panel 19 was weighted by a factor of 0.500, reflecting approximately the distribution of the overall sample between the two panels. The resulting combined response rate for the combined panels was computed as (0.500 x 48.6) plus (0.500 x 48.5) or 48.5 percent (as shown in Table 3.1).

3.2.5 Oversampling

Oversampling is a feature of the MEPS sample design, helping to increase the precision of estimates for some subgroups of interest. Before going into details related to MEPS, the concept of oversampling will be discussed.

In a sample where all persons in a population are selected with the same probability and survey coverage of the population is high, the sample distribution is expected to be proportionate to the population distribution. For example, if Hispanics represent 15 percent of the general population, one would expect roughly 15 percent of the persons sampled to be Hispanic. However, in order to improve the precision of estimates for specific subgroups of a population, one might decide to select samples from those subgroups at higher rates than the remainder of the population. Thus, one might select Hispanics at twice the rate (i.e., at double the probability) of persons not oversampled. As a result, an oversampled subgroup comprises a higher proportion of the sample than it represents in the general population. Sample weights ensure that population estimates are not distorted by a disproportionate contribution from oversampled subgroups. Base sample weights for oversampled groups will be smaller than for the portion of the population not oversampled. For example, if a subgroup is sampled at roughly twice the rate of sample selection for the remainder of the population not oversampled, members of the oversampled subgroup will receive base or initial sample weights (prior to nonresponse or poststratification adjustments) that are roughly half the size of the group not oversampled.

As mentioned above, oversampling is implemented to increase the sample sizes and thus improve the precision of survey estimates for particular subgroups of the population. The “cost” of oversampling is that the precision of estimates for the general population and subgroups not oversampled will be reduced to some extent compared to the precision one could have achieved if the same overall sample size were selected without any oversampling.

The oversampling of Hispanic and Black households for the NHIS carries over to MEPS through the set of NHIS responding households eligible for sample selection for MEPS. In the NHIS under the old sample design, Hispanic households were oversampled at a rate of roughly 2 to 1. That is, the probability of selecting a Hispanic household for participation in the NHIS was roughly twice that for households in the general population that were not oversampled. The oversampling rate for Black households under the old design was roughly 1.5 to 1. Under the new NHIS sample design Asians, as well as Hispanics and Blacks, are oversampled. The average oversampling rates for the three minority groups have not yet been reported.

For both Panel 18 and Panel 19, all households in the Asian, Hispanic, and Black domains were sampled with certainty (i.e., all households assigned to those domains were included in the MEPS). For Panel 18, the “Other, complete” domain was sampled at a rate of about 63 percent while the “Other, partial complete” domain was sampled at a rate of about 43 percent. For Panel 19, the corresponding sampling rates for the “Other, complete” domain and the “Other, partial complete” domain were about 66 percent and 42 percent, respectively.

Within strata (domains) for both panels, responding NHIS households were selected for MEPS using a systematic sample selection procedure from among those eligible. For the “non-Other” strata households were all selected with certainty. Within strata involving “Others” (two strata for both panels) the selection was with probability proportionate to size (pps) where the size measure was the inverse of the NHIS initial probability of selection. The pps sampling was undertaken to help reduce the variability in the MEPS weights incurred due to the variability of the NHIS sampling rates. With the subsampling, households that were oversampled for MEPS in calendar year 2014 were those responding households in the NHIS identified as having members whose race/ethnicity was Hispanic, Black, or Asian for both panels.

Typically, sample allocations across sample domains change from one MEPS panel to another. The sample domains used may also vary by panel although this was not the case for Panel 18 and Panel 19. When one compares unweighted measures (e.g., response rates) between panels and years, one should take into account such differences. If, for example, members of one domain have a lower propensity to respond than those of another domain, then if that domain has been allocated a higher proportion of the sample, the corresponding panel may have a lower unweighted response rate simply because of the differences in sample allocation.

Within each domain (sample stratum) systematic samples of the MEPS-eligible households were selected from among the NHIS household respondents made available for MEPS sample selection purposes.

3.3 Person-Level Weight (PERWT14F)

3.3.1 Overview

There is a single full year person-level weight (PERWT14F) assigned to each record for each key, in-scope person who responded to MEPS for the full period of time that he or she was inscope during 2014. A key person was either a member of a responding NHIS household at the time of interview or joined a family associated with such a household after being out-of-scope at the time of the NHIS (the latter circumstance includes newborns as well as those returning from military service, an institution, or residence in a foreign country). A person is inscope whenever he or she is a member of the civilian noninstitutionalized portion of the U.S. population.

3.3.2 Details on Person-Level Weights Construction

The person-level weight PERWT14F was developed in several stages. First, person-level weights for Panel 18 and Panel 19 were created separately. The weighting process for each panel included adjustments for nonresponse over time and a calibration to independent population totals. The calibration was initially accomplished separately for each panel by raking the corresponding sample weights to Current Population Survey (CPS) population estimates based on five variables. The five variables used in the establishment of the initial person-level control figures were: census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic; Black, non-Hispanic; Asian, non-Hispanic; and other); sex; and age. A 2014 composite weight was then formed by multiplying each individual panel weight by a factor which reflected the relative sample size of the individual panel compared to the sample size for the two panels combined. The individual panel weights from Panel 18 were multiplied by the factor .500 and each weight from Panel 19 by the factor .500. Using such factors to form composite weights serves to limit the variance of estimates obtained from pooling the two samples. The resulting composite weight was raked to the same set of CPS-based control totals. Then, when the poverty status information (derived from the MEPS income variables) became available, another raking was to be undertaken, using dimensions reflecting poverty status in addition to the previously mentioned five variables. Control totals were established using poverty status (five categories: below poverty, from 100 to 125 percent of poverty, from 125 to 200 percent of poverty, from 200 to 400 percent of poverty, and at least 400 percent of poverty) for this purpose. Thus, the raking for the final weight reflected poverty status as well as the other five variables previously used in the weight calibration.

3.3.3 MEPS Panel 18 Weight Development Process

The person-level weight for MEPS Panel 18 was developed using the 2013 full year weight for an individual as a “base” weight for survey participants present in 2014. For key, in-scope members who joined an RU some time in 2014 after being out-of-scope in 2013, the initially assigned person-level weight was the corresponding 2013 family weight. The weighting process included an adjustment for nonresponse over Rounds 4 and 5 as well as a raking to population control figures for December 2014. These control figures were derived by scaling back the population totals obtained from the March 2015 CPS to correspond to a national estimate for the civilian noninstitutionalized population to reflect the December 31, 2014 estimated population total (estimated based on Census projections for January 1, 2015). Variables used in the establishment of person-level control figures included: census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic; Black, non-Hispanic; Asian, non-Hispanic; and other); sex; and age. For confidentiality reasons, the MSA status variables are no longer released for public use (this policy began in 2013). The final weight for key, responding persons who were not inscope on December 31, 2014 but were inscope earlier in the year was the weight after the nonresponse adjustment.

3.3.4 MEPS Panel 19 Weight Development Process

The person-level weight for MEPS Panel 19 was developed using the MEPS Round 1 person-level weight as a “base” weight. The MEPS Round 1 weights incorporated the following components: the original household probability of selection for the NHIS, ratio-adjustment to NHIS-based national population estimates at the household (occupied dwelling unit) level, adjustment for nonresponse at the dwelling unit level for Round 1, and poststratification to figures at the family and person level obtained from the March CPS data base of the corresponding year (i.e., 2013 for Panel 18 and 2014 for Panel 19). For key, in-scope respondents who joined an RU after Round 1, the Round 1 family weight served as a “base” weight.

The weighting process also included an adjustment for nonresponse over Round 2 and the 2014 portion of Round 3 as well as raking to the same population control figures for December 2014 used for the MEPS Panel 18 weights. The same five variables employed for Panel 18 raking (census region, MSA status, race/ethnicity, sex, and age) were used for Panel 19 raking. Similarly, for Panel 19, key, responding persons not inscope on December 31, 2014 but inscope earlier in the year retained, as their final Panel 19 weight, the weight after the nonresponse adjustment.

3.3.5 The Final Person-Level Weight for 2014

The composite weights of two groups of persons who were out-of-scope on December 31, 2014 were poststratified. Specifically, the weights of those who were inscope some time during the year, out-of-scope on December 31, and entered a nursing home during the year were poststratified to a corresponding control total obtained from the 1996 MEPS Nursing Home Component. The weights of persons who died while inscope during 2014 were poststratified to corresponding estimates derived using data obtained from the Medicare Current Beneficiary Survey (MCBS) and Vital Statistics information available from the National Center for Health Statistics (NCHS). Separate decedent control totals were developed for the “65 and older” and “under 65” civilian noninstitutionalized populations.

The sum of the person-level weights across all persons assigned a positive person-level weight, (i.e., for the civilian, noninstitutionalized or in-scope population over the course of the year (based on PERWT14F>0) is 318,440,423 (see Table 3.2). The corresponding total for the population that was inscope on December 31, 2014 is 314,906,436.

3.3.6 A Note on MEPS Population Estimates

Beginning with the 2011 Full Year data, MEPS transitioned to 2010 census-based population estimates from the CPS for poststratification and raking. CPS estimates began reflecting 2010 census-based data in 2012, and the March 2015 CPS data serve as the basis for the 2014 MEPS weight calibration efforts. An article discussing the impact of this transition on CPS estimates can be found at http://www.bls.gov/cps/cps12adj.pdf.

Use of the updated population controls will have a noticeable effect on estimated totals for some population subgroups. The article compares some 2011 CPS estimates for those aged 16 and older “as published” with those that would have been generated had the updated population controls been used. Among the more notable increases were for the following subgroups: those aged 55 or older (about 1.3 million more, a 1.7 percent increase); those aged 16-24 (about a half million more, a 1.4 percent increase); Blacks (400 thousand more, a 1.4 percent increase); Hispanics (1.3 million more, a 3.8 percent increase); and Asians (1.2 million more, a 10 percent increase). Corresponding changes can be anticipated for MEPS full year data beginning with the 2011 MEPS PUF.

3.4 Coverage

The target population associated with this MEPS database is the 2014 U.S. civilian, noninstitutionalized population. However, the MEPS sampled households are a subsample of the NHIS households interviewed in 2012 (Panel 18) and 2013 (Panel 19). New households created after the NHIS interviews for the respective panels and consisting exclusively of persons who entered the target population after 2012 (Panel 18) or after 2013 (Panel 19) are not covered by MEPS. Neither are previously out-of-scope persons who join an existing household but are unrelated to the current household residents. Persons not covered by a given MEPS panel thus include some members of the following groups: immigrants, persons leaving the military, U.S. citizens returning from residence in another country, and persons leaving institutions. Those not covered represent only a small proportion of the MEPS target population.

3.5 Background on Family-Level Estimation Using This MEPS Public Use File

3.5.1 Overview

There are two family weight variables provided in this release: FAMWT14F and FAMWT14C. FAMWT14F can be used to make estimates for the cross-section of families in the U.S. civilian noninstitutionalized population on December 31, 2014 where families are identified based on the MEPS definition of a family unit. Estimates can include MEPS families that existed at some time during 2014 but whose members became out-of-scope prior to the end of the year (e.g., all family members moved out of the country, died, etc.) as well as MEPS families in existence on December 31, 2014. FAMWT14C can be used to make estimates for the cross-section of families in the U.S. civilian, noninstitutionalized population on December 31, 2014 where families are identified based on the CPS definition of a family unit.

3.5.2 Definition of “Family” for Estimation Purposes

A MEPS family generally consists of two or more persons living together in the same household who are related by blood, marriage, or adoption, as well as foster children (foster children are not included as members under the CPS definition of a family). MEPS also defines as a family unmarried persons living together who consider themselves a family unit (these are not families under the CPS definition). Single people who live with neither a relative nor a person identified as a “significant other” have also been assigned a family ID value and a family-level weight. Thus, they can be included or excluded from family-level estimates, as desired. Relatives identified as usual residents of the household who were not present at the time of the interview, such as college students living away from their parents’ home during the school year, were considered as members of the family that identified them.

To make estimates at the family level, it is necessary to prepare a family-level file containing one record per family (see instructions below), family-level summary characteristics, and the family-level weight variable (FAMWT14F or FAMWT14C). Each MEPS family unit is uniquely identified by the combination of the variables DUID and FAMIDYR while each CPS family unit is uniquely identified by the combination of the variables DUID and CPSFAMID. The number of persons in a MEPS sample family ranges from 1 to 14 and the number in the CPS families ranges from 1 to 14. Only persons with positive nonzero family weight values are candidates for inclusion in family estimates.

Two sets of families for whom estimates can be obtained are defined in Table 3.3 below (along with respective sample sizes). Persons with FMRS1231=1 were inscope for the survey on 12/31/14 and therefore part of a MEPS family on 12/31/14. The more expansive definition of families (second row in Table 3.3) includes families and members of families who were not inscope at the end of the year. While MEPS includes individual persons as family units (about one-third of all units), analysts may restrict their analyses to families with two or more members using the family size variables shown in Table 3.3 (for example, to limit consideration to the cross-section of families with two or more members on December 31, 2014, analyze only families where FAMS1231 is 2 or more). Estimates can also be made for the cross-section of CPS families on December 31, 2014 based on the 14,133 sample CPS families in this data file.

3.5.3 Instructions to Create Family Estimates

The following is a summary of the steps and the variables to be used for family-level estimation based on the MEPS definition of families.

Concatenate the variables DUID and FAMIDYR into a new variable (e.g., DUIDFAMY).
To create a family-level file, sort by DUIDFAMY and then subset to one record per DUIDFAMY value by retaining only the reference person record (FAMRFPYR=1) for each value of DUIDFAMY. Some family-level measures needed for analytic purposes (e.g., means or totals) can be obtained after aggregating person-level information across all members of a family. For other types of measures, analysts frequently use the characteristics of the reference person to characterize his or her family unit (e.g., the race/ethnicity, marital status, or age of the reference person).
Apply the weight FAMWT14F to the analytic variable(s) of interest to obtain national MEPS family estimates.

3.5.4 Details on Family Weight Construction and Estimated Number of Families

Because health care related decisions are influenced by a family's economic status, poverty status is incorporated into the poststratification component of the weighting process. However, poverty status is defined based on the CPS definition of a family, which differs from the MEPS family definition in two ways: foster children are not considered family members and unmarried partners living together are considered separate family units. Since data are collected in MEPS family units (RUs), prior to poststratification MEPS families in existence on December 31, 2014 containing either unmarried partners living together or foster children were partitioned into units that correspond to CPS families (families with no unmarried partners or foster children are defined as family units in both MEPS and CPS).

The process of calibrating the family weights to achieve consistency with CPS control figures was carried out in several steps. First, all CPS-like family units were assigned an initial family-level weight based on the person-level weight (PERWT14F) of the family reference person (FAMRFPYR=1) of the MEPS family with which they were associated. These CPS family-level weights (FAMWT14C) were obtained by raking to population control figures derived from CPS estimates for December 2014 (derived by scaling the family population totals from the March 2015 CPS back to reflect December 31, 2014). In addition to poverty status, the calibration process for the family-level weights incorporated the following variables: Census region; MSA status; race/ethnicity of reference person (Hispanic, Black but non-Hispanic, Asian, and other); family type (reference person married, living with spouse; male reference person, unmarried or spouse not present; female reference person, unmarried or spouse not present); age of reference person; and family size on December 31, 2014. The family-level weight variable for MEPS families (FAMWT14F) was then constructed by putting MEPS families that consisted of more than one CPS-like family back together and assigning the MEPS family-level weight based on the CPS family weight of the MEPS family reference person.

The weighted population estimate for CPS families on December 31, 2014 based on 14,133 CPS families in the sample is 140,282,371. Overall, the weighted population estimate for the 13,330 MEPS family units containing at least one member of the U.S. civilian, noninstitutionalized population on December 31, 2014 (those families whose members have FAMWT14F>0 and FMRS1231=1) is 135,130,158. The inclusion of families whose members left the in-scope population prior to December 31, 2014 increases the estimated total number of families represented by the 13,421 MEPS responding families (whose members have FAMWT14F>0) to 136,409,255.

It may be of interest to note that CPS is planning to incorporate the ability to identify same sex marriages but this has yet to be implemented. Thus, the MEPS raking effort to CPS family control figures serving to reflect consistent population distributions between MEPS’ “CPS-like families” and CPS families does not incorporate that component of the population. It should be noted that MEPS families (as opposed to the MEPS “CPS-like families”) have been based on self-identification as well as legal and biological relationships. People who self-identify as a family unit, regardless of marital status, have been considered a MEPS family for analytic purposes.

3.6 Analysis Using Health Insurance Eligibility Units

To construct a weight for use in analysis using Health Insurance Eligibility Units, as identified by the variable HIEUIDX:

Identify the HIEU head by your analytic intent, i.e. if only studying health insurance unit with female heads of households, choose the female adult as head of household.
If the weight of the HIEU head is non-zero, use the weight of the HIEU head for all members of that HIEU; or

If the weight of the HIEU head is zero, delete the case.

3.7 Weights and Response Rates for the Self-Administered Questionnaire

For analytic purposes, a single person-level weight variable, SAQWT14F, has been provided for use with the data obtained from the Self-Administered Questionnaire (SAQ). This questionnaire was administered in Panel 19, Round 2 and Panel 18, Round 4 and was to be completed by each adult (person aged 18 or older) in the family. Thus, the target population for the SAQ is adults in the civilian, noninstitutionalized population at the time data were collected for Rounds 2/4 (generally speaking, the fall of the year in question).

The final full-year person-level SAQ weight for 2014 was constructed as follows. First, the weight variable was developed by adjusting for questionnaire non-response. Variables used in the nonresponse adjustment process were region, MSA status, family size, marital status, level of education, health status, health insurance status, age, sex, and race/ethnicity. Then the weights were raked to Current Population Survey (CPS) estimates corresponding to December 2014 (the same source of control figures used for the full year person weights). The variables used to form control figures (region, MSA status, age, sex, and race/ethnicity) are the same variables that were used for the full year person weights. The only difference was that age categories were developed after excluding ages under 18, since only adults were eligible for the SAQ. The two raking efforts were used for the 2014 Consolidated file in order to maintain consistency with how the sample weights were computed in previous years.

The final 2014 SAQ weight for this consolidated data file was then obtained by raking the preliminary weight to CPS estimates that were based on poverty status as well as the aforementioned variables. This final weight was assigned the variable name SAQWT14F.

In all, there were 21,213 persons assigned an SAQ weight with the sum of the weights being 241,067,874 (an estimate of the civilian, noninstitutionalized population aged 18 or older at the time the SAQ was administered).

The Panel 18 unweighted response rate for the 2014 SAQ was 89.7 percent, while the Panel 19 unweighted response rate for the 2014 SAQ was 87.6 percent. Pooled unweighted response rates for the survey respondents have been computed by taking a weighted average of the panel-specific response rates, where the weights were the relative proportion of persons with sample weights associated with each panel (a value of .500 was associated with Panel 18, and a value of .500 was associated with Panel 19). The pooled unweighted response rate for the combined panels for the 2014 SAQ is 88.7 percent.

3.8 Weights and Response Rates for the Diabetes Care Survey

A person-level weight, DIABW14F, was developed for use with the data obtained from the Diabetes Care Survey (DCS). This weight was assigned to each person with a SAQ weight who was also classified as having diabetes (thus, no one aged 17 or under receives a DCS weight).

Prior to Panel 12, the identification of people eligible to receive the DCS questionnaire was focused on the Rounds 3/5 interview. During the Rounds 3/5 regular MEPS interview, each RU respondent was asked to complete a “conditions” question to identify all current/deceased/institutionalized RU members of any age who had been diagnosed with diabetes. Each RU member who was identified as having diabetes by the RU respondent was then eligible to receive the DCS questionnaire. To determine which DCS respondents actually had diabetes (and thus were members of the target population), each DCS respondent was asked if s/he was told by a physician that s/he had diabetes. While the DCS questionnaire has been distributed to persons under the age of 18, the constructed DCS variables released in the person-level PUF apply only to adults. Beginning in Panel 12, a different screening process has been employed to identify those eligible to receive the DCS questionnaire. This process involves asking screener questions in each round, but the group of persons about whom these questions asks varies from round to round.

In Round 1, the RU respondent is asked to identify all RU members over the age of 17 (including those who went out of scope unless they died prior to the date of interview) with diabetes. In Rounds 2/4, the same screening information is gathered but only for new RU members over the age of 17 (as long as they did not die during the round). In Rounds 3/5 the screening questions are asked of the RU respondent for all RU members over the age of 17 who were: (a) inscope sometime during the round but had not died prior to the date of interview; and (b) had not been identified as having diabetes in a previous round (this includes people with nonresponse data and/or classified as not having diabetes in all previous rounds of MEPS plus all new members of the RU in Rounds 3/5). Also in Rounds 3/5, an RU respondent may indicate that an RU member previously identified as having diabetes actually does not have diabetes. Any RU member who has been identified by the RU respondent as having diabetes (and not later negated in Rounds 3/5) at any time during MEPS will be asked to complete a DCS questionnaire. This process has been designed to help ensure that all RU members with diabetes will be given a DCS questionnaire to complete.

In all, 2,138 people were assigned a DCS weight (DIABW14F>0). The sum of the DCS weights is 24,588,839, an estimate of the adult population self-reporting as having been diagnosed with diabetes based on the two step process described above.

The Panel 18 unweighted response rate for the 2014 DCS was 88.5 percent. The Panel 19 unweighted response rate for the 2014 DCS was 88.4 percent. The pooled unweighted response rate for the combined panels for the DCS is 88.4 percent. The pooled unweighted response rate is a weighted average for the two panels, reflecting their relative sample sizes (roughly 50 percent of the MEPS respondents are from Panel 19, the remaining 50 percent from Panel 18).

3.9 Variance Estimation

The MEPS is based on a complex sample design. To obtain estimates of variability (such as the standard error of sample estimates or corresponding confidence intervals) for MEPS estimates, analysts need to take into account the complex sample design of MEPS for both person-level and family-level analyses. Several methodologies have been developed for estimating standard errors for surveys with a complex sample design, including the Taylor-series linearization method, balanced repeated replication, and jackknife replication. Various software packages provide analysts with the capability of implementing these methodologies. Replicate weights have not been developed for these MEPS data. Instead, the variables needed to calculate appropriate standard errors based on the Taylor-series linearization method are included on this and all other MEPS public use files. Software packages that permit the use of the Taylor-series linearization method include SUDAAN, Stata, SAS (version 8.2 and higher), and SPSS (version 12.0 and higher). For complete information on the capabilities of each package, analysts should refer to the corresponding software user documentation.

Using the Taylor-series linearization method, variance estimation strata and the variance estimation PSUs within these strata must be specified. The variables VARSTR and VARPSU on this MEPS data file serve to identify the sampling strata and primary sampling units required by the variance estimation programs. Specifying a “with replacement” design in one of the previously mentioned computer software packages will provide estimated standard errors appropriate for assessing the variability of MEPS survey estimates. It should be noted that the number of degrees of freedom associated with estimates of variability indicated by such a package may not appropriately reflect the number available. For variables of interest distributed throughout the country (and thus the MEPS sample PSUs), one can generally expect to have at least 100 degrees of freedom associated with the estimated standard errors for national estimates based on this MEPS database.

Prior to 2002, MEPS variance strata and PSUs were developed independently from year to year, and the last two characters of the strata and PSU variable names denoted the year. However, beginning with the 2002 Point-in-Time PUF, the variance strata and PSUs were developed to be compatible with all future PUFs until the NHIS design changed. Thus, when pooling data across years 2002 through the Panel 11 component of the 2007 files, the variance strata and PSU variables provided can be used without modification for variance estimation purposes for estimates covering multiple years of data. There were 203 variance estimation strata, each stratum with either two or three variance estimation PSUs.

From Panel 12 of the 2007 files, a new set of variance strata and PSUs were developed because of the introduction of a new NHIS design. There are 165 variance strata with either two or three variance estimation PSUs per stratum starting from Panel 12. Therefore, there are a total of 368 (203+165) variance strata in the 2007 Full Year file as it consists of two panels that were selected under two independent NHIS sample designs. Since both MEPS panels in the Full Year 2008 file and beyond are based on the new NHIS design, there are only 165 variance strata. These variance strata (VARSTR values) have been numbered from 1001 to 1165 so that they can be readily distinguished from those developed under the former NHIS sample design in the event that data are pooled for several years.

If analyses call for pooling MEPS data across several years, in order to ensure that variance strata are identified appropriately for variance estimation purposes, one can proceed as follows:

When pooling any year from 2002 or later, one can use the variance strata numbering as is.
When pooling any year from 1996 to 2001 with any year from 2002 or later, use the H36 file.
The H36 file is updated every year to allow pooling of any year from1996 to 2001 with any year from 2002 up to the latest year.

3.10 Guidelines for Determining which Weight to Use for Analyses Involving Data/Variables from Multiple Sources and Supplements: MEPS 2014 Full-Year Use File

Which weight variable to use is decided based on a hierarchy.

For person-level analyses not involving variables from the SAQ or DCS, PERWT14F should always be used.

For person-level analysis involving variables from the SAQ but not the DCS, the SAQWT14F should be used. For example, if examining access to care or quality of care variables from the SAQ by socio-demographics, health status, or health insurance status, SAQWT14F is the appropriate weight even though person-level socio-demographic, health status, and health insurance status variables are part of the core person-level questionnaire. Whenever data from the Diabetes Care Survey (DCS) are used, alone or in conjunction with data from other questionnaires, the weight variable DIABW14F should be used for those eligible to provide DCS data.

For all family-level analyses, FAMWT14F or FAMWT14C should be used.

3.11 Using MEPS Data for Trend Analysis

MEPS began in 1996, and the utility of the survey for analyzing health care trends expands with each additional year of data; however, there are a variety of methodological and statistical considerations when examining trends over time using MEPS. Examining changes over longer periods of time can provide a more complete picture of underlying trends. In particular, large shifts in survey estimates over short periods of time (e.g. from one year to the next) that are statistically significant should be interpreted with caution unless they are attributable to known factors such as changes in public policy, economic conditions, or survey methodology.

In 2013 MEPS survey operations introduced an effort to obtain more complete information about health care utilization from MEPS respondents with full implementation in 2014. This effort resulted in improved data quality and a reduction in underreporting in the second half of 2013 and throughout 2014. The impacts of these efforts are important to consider. Respondents reported more visits, especially non-physician visits, by sample members and the increase in the number of reported visits was especially large at the tail of the distribution. Consequently, there is a break in trend among people who are more likely to be in that tail, such as the elderly, Medicare beneficiaries, and people with multiple chronic conditions, disabilities, or poor health. In turn, spending on visits also increased, especially in the tail and for these subgroups. These increases in service use and expenditures were not uniform throughout the country, and respondents in the West South Central Census Division reported less increase in use, especially for non-minority sample members. Data users comparing service use and expenditures across states, regions, or racial and ethnic groups, particularly before and after 2013, may take this lack of uniformity into account by working in data centers, which provide access to restricted data files containing the Census Division variable. See: meps.ahrq.gov/data_stats/onsite_datacenter.jsp

Changes to the MEPS survey instrument should also be considered when analyzing trends. For example, users should refer to section 2.5.11.2 above and, for more detail, the documentation for the prescription drug file (HC-168A) when analyzing prescription drug spending before and after 2010 and 2011. Similarly, as a result of improved methods for collecting priority conditions data implemented in 2007, prevalence measures prior to 2007 are not comparable to those from 2007 and beyond for many of these conditions. Users should refer to Section 2.5.4 above and the documentation for the conditions file (HC-170) for details. Data users should review relevant sections of the documentation for descriptions of these types of changes before undertaking trend analyses.

Analysts may also wish to consider using statistical techniques to smooth or stabilize analyses of trends using MEPS data such as comparing pooled time periods (e.g. 1996-97 versus 2012-13), working with moving averages or using modeling techniques with several consecutive years of MEPS data to test the fit of specified patterns over time.

Finally, statistical significance tests should be conducted to assess the likelihood that observed trends are not attributable to sampling variation. In addition, researchers should be aware of the impact of multiple comparisons on Type I error. Without making appropriate allowance for multiple comparisons, undertaking numerous statistical significance tests of trends increases the likelihood of concluding that a change has taken place when one has not.
