B. Background
This documentation describes one in a series of public use files from the Medical Expenditure Panel Survey (MEPS). The survey provides a new and extensive data set on the use of health services and health care in the United States.
The Medical Expenditure Panel Survey (MEPS) is conducted to provide nationally representative estimates of health care use, expenditures, sources of payment, and insurance coverage for the U.S. civilian non-institutionalized population. MEPS also includes a nationally representative survey of nursing homes and their residents. MEPS is cosponsored by the Agency for Healthcare Research and Quality (AHRQ) and the National Center for Health Statistics (NCHS).
MEPS comprises four component surveys: the Household Component (HC), the Medical Provider Component (MPC), the Insurance Component (IC), and the Nursing Home Component (NHC). The HC is the core survey, and it forms the basis for the MPC sample and part of the IC sample. The separate NHC sample supplements the other MEPS components. Together these surveys yield comprehensive data that provide national estimates of the level and distribution of health care use and expenditures, support health services research, and can be used to assess health care policy implications.
MEPS is the third in a series of national probability surveys conducted by AHRQ on the financing and use of medical care in the United States. The National Medical Care Expenditure Survey (NMCES, also known as NMES-1) was conducted in 1977, the National Medical Expenditure Survey (NMES-2) in 1987. Beginning in 1996, MEPS continues this series with design enhancements and efficiencies that provide a more current data resource to capture the changing dynamics of the health care delivery and insurance system.
The design efficiencies incorporated into MEPS are in accordance with the Department of Health and Human Services (DHHS) Survey Integration Plan of June 1995, which focused on consolidating DHHS surveys, achieving cost efficiencies, reducing respondent burden, and enhancing analytical capacities. To accommodate these goals, new MEPS design features include linkage with the National Health Interview Survey (NHIS), from which the sampling frame for the MEPS HC is drawn, and continuous longitudinal data collection for core survey components. The MEPS HC augments NHIS by selecting a sample of NHIS respondents, collecting additional data on their health care expenditures, and linking these data with additional information collected from the respondents’ medical providers, employers, and insurance providers.

1.0 Household Component
The MEPS HC, a nationally representative survey of the U.S. civilian non-institutionalized population, collects medical expenditure data at both the person and household levels. The HC collects detailed data on demographic characteristics, health conditions, health status, use of medical care services, charges and payments, access to care, satisfaction with care, health insurance coverage, income, and employment.
The HC uses an overlapping panel design in which data are collected through a preliminary contact followed by a series of five rounds of interviews over a 2 ½-year period. Using computer-assisted personal interviewing (CAPI) technology, data on medical expenditures and use for 2 calendar years are collected from each household. This series of data collection rounds is launched each subsequent year on a new sample of households to provide overlapping panels of survey data and, when combined with other ongoing panels, will provide continuous and current estimates of health care expenditures.
The sampling frame for the MEPS HC is drawn from respondents to NHIS, conducted by NCHS. NHIS provides a nationally representative sample of the U.S. civilian non-institutionalized population, with oversampling of Hispanics and blacks.

2.0 Medical Provider Component
The MEPS MPC supplements and validates information on medical care events reported in the MEPS HC by contacting medical providers and pharmacies identified by household respondents. The MPC sample includes all hospitals, hospital physicians, home health agencies, and pharmacies reported in the HC. Also included in the MPC are all office-based physicians:
- Providing care for HC respondents receiving Medicaid.
- Associated with a 75-percent sample of HC households receiving care through an HMO (health maintenance organization) or managed care plan.
- Associated with a 25-percent sample of the remaining HC households.
Data are collected on medical and financial characteristics of medical and pharmacy events reported by HC respondents, including:
- Diagnoses coded according to ICD-9-CM (9th Revision, International Classification of Diseases) and DSM-IV (Fourth Edition, Diagnostic and Statistical Manual of Mental Disorders).
- Physician procedure codes classified by CPT-4 (Common Procedure Terminology, Version 4).
- Inpatient stay codes classified by DRGs (diagnosis-related groups).
- Prescriptions coded by national drug code (NDC), medication names, strength, and quantity dispensed.
- Charges, payments, and the reasons for any difference between charges and payments.
The MPC is conducted through telephone interviews and mailed survey materials.

To Table Of Contents
3.0 Insurance Component
The MEPS IC collects data on health insurance plans obtained through employers, unions, and other sources of private health insurance. Data obtained in the IC include the number and types of private insurance plans offered, benefits associated with these plans, premiums, contributions by employers and employees, eligibility requirements, and employer characteristics.
Establishments participating in the MEPS IC are selected through four sampling frames:
- A list of employers or other insurance providers identified by MEPS HC respondents who report having private health insurance at the Round 1 interview.
- A Bureau of the Census list frame of private sector business establishments.
- The Census of Governments from Bureau of the Census.
- An Internal Revenue Service list of the self-employed.
To provide an integrated picture of health insurance, data collected from the first sampling frame (employers and insurance providers) are linked back to data provided by the MEPS HC respondents. Data from the other three sampling frames are collected to provide annual national and State estimates of the supply of private health insurance available to American workers and to evaluate policy issues pertaining to health insurance.
The MEPS IC is an annual panel survey. Data are collected from the selected organizations through a prescreening telephone interview, a mailed questionnaire, and a telephone followup for nonrespondents.

301 Moved Permanently
It is being released as a research file and has not undergone the standard quality control procedures usually performed on MEPS public use data files. The file includes a total of 41,406 records, with each record representing a unique job for a person by round. For this file, only information for jobs starting on or before 12/31/1998 is presented. Information on jobs starting in 1999 will be contained in the 1999 MEPS Jobs file release.

2.0 Data File Description
The unique record identifier is the variable JOBSIDX which is comprised of a person identifier (DUID + PID), a round identifier (RN), and a job number (JOBSN). A panel indicator (PANEL) is included on the files to distinguish Round 3 jobs held by Panel 2 persons from Round 3 jobs held by those in Panel 3.
Each job record contains original variables related to the employment section of the 1998 MEPS household survey. All persons aged 16 and older in the MEPS can report any number of jobs held within a round. Persons who held more than one job at the round’s interview date (a current job) were asked to identify the main job. This job was classified as the current main job and all other simultaneously held jobs were classified as miscellaneous. The MEPS also obtained some information on prior jobs held in the reference period and, for those persons not currently working and having no job in the reference period, some information on the last job the person held. Additionally, for those persons age 55 and older who indicated that they retired from a job, the MEPS obtained some job-level data on the retirement job. The variable SUBTYPE indicates the type of job record
-
current main, current miscellaneous, former main, former miscellaneous, last job outside reference period, or retirement job. It is important to note that the retirement job classification in the variable SUBTYPE is independent of the retirement response in the variable relating to the question why a person left a previous job (YLEFT). The MEPS asked for detailed information about any job classified as current main or current miscellaneous and basic information about any other job types. Refer to the questionnaire to see which information was asked for each job type.
The MEPS used dependent interviewing in Rounds 3, 4, and 5 for Panel 2 and in Rounds 2 and 3 for Panel 3. In these rounds, the MEPS asked persons who held current main and current miscellaneous jobs at the previous round interview date whether they were still working at these jobs (see section RJ in the employment section). If a person still held a current main job from the previous round, the MEPS asked whether the job was still the main job. Most persons reported that they still worked at the same job and it was still their main job. If job status remained the same, the MEPS asked only a subset of the employment questions. Because the MEPS asked only this subset of questions if job status for a person did not change in later rounds, many job level variables on the subsequent round job records are coded as inapplicable; the complete information is on the jobs record for the job in a previous round. Thus it is important to determine whether a job in a subsequent round continues from the previous round when working with the job records. In rounds where this applies, the variables STILLAT (for jobs that were current main in the previous round) and STILLWRK (for jobs that were current miscellaneous in the previous round) indicate whether a person still holds the job at the subsequent round interview date. The variable SUBTYPE on the subsequent round job record indicates whether the job is main or miscellaneous in that subsequent round. Note that if a Panel 2 Round 3-5 job is continued from a Round 1 or 2 job, much of the information will be contained in the 1997 MEPS Jobs file (HC-019). Use that file to obtain the desired job characteristics. A sample SAS program showing how to do this is provided in Appendix 1. Variables that relate only to the review of a job reported in a previous round (Y_CHANGE, OFFTAKEI, NOWTAKEI, WHY_LEFT, STILLAT, STILLWRK, DIFFWAGE, WHY_DIFF, WORKSTAT, and SHFTCHNG) were not asked in Round 1 and these variables are coded as inapplicable.
There are two variables on the file which, while skipped over as inapplicable during the actual interview process in rounds subsequent to the one in which the job was initially reported, have their original value carried forward on the database from round to round. The variables are MORELOC and NUMEMPS. This treatment is due to special internal processing needs. Unlike the situation for many other variables, as explained above, values other than inapplicable for MORELOC and NUMEMPS do not necessarily mean that a job is newly reported, as they may be carried forward from an earlier round.
In the review section (RJ), the MEPS attempted to obtain information regarding changes in wages for the same job from round to round; however in many cases, but not all, wage changes of less than $.50 per hour on the same job were not recorded. This caution applies only to individual jobs that did not change. For every new job reported for a person, the MEPS attempted to obtain up-to-date wage information.
For reasons of confidentiality, the hourly wage variable (HRLYWAGE) was topcoded. A value of -10 indicates that the hourly wage rate was greater than or equal to $76.00. Additionally, the value of any other earnings on a job (BONSAMT, COMMAMT, TIPSAMT, DAYWAGE, WKLYAMT, GROSSPAY, MAKEAMT, OTHRWAGE) with a calculated hourly wage greater than or equal to $76.00 was also capped. To calculate the hourly wage for these other types of compensation, the number of hours per week worked and in some cases the number of weeks worked were used in conjunction with the various amounts. (These calculated hourly wages do not appear on the file.) Compensation variables were not reconciled with income data collected elsewhere in the MEPS. Additionally, for confidentiality, establishment size variables (NUMEMPS - jobs held by wage earners, ESTMATE1 - estimate of establishment size for jobs held by wage earners, and TOTLEMP - self-employed jobs) were topcoded as -10 for sizes greater than or equal to 10,000.
Due to many skip patterns in the instrument, it is recommended that users of these data become familiar with the employment section in the MEPS questionnaire. To aid users, a crosswalk between variables and MEPS questionnaire numbers is provided in this release. The following examples of variables involved in skip patterns are presented to be illustrative; these examples do not represent the full range of variables affected by questionnaire skip patterns. In one example of a skip pattern, the MEPS did not obtain job-related benefits such as vacation, sick leave and pension information for self-employed jobs, so those variables are coded as inapplicable (-1) for those types of jobs. Nor did the MEPS attempt to obtain wage, salary, and information regarding whether the job was in the private sector, federal or local government (TYPEEMPL) for the self-employed. So again, due to the skip pattern, TYPEEMPL is coded as inapplicable for self-employed jobs. Conversely, the questions relating to business organization type (BUSINC, PROPRIET) were asked only of the self-employed, so the skip pattern results in those variables being coded inapplicable for jobs performed by wage earners.
It is important to note that the establishment size variable for the self-employed is TOTLEMP while the establishment size for wage earners can be found in NUMEMPS and ESTMATE1. The variable ESTMATE1 is derived from a question that allowed wage earners who did not know the actual establishment size (NUMEMPS) to choose from a number of size ranges. Industry codes (INDTCODX) and occupation codes (OCCPCODX) were coded by professional coders from verbatim responses.
This file does not include any weights. To make person level estimates, link to any of the 1998 files and use the person level weight for the appropriate panel. The link should be made through the variable DUPERSID. Note that not all persons in the MEPS have positive weights.
