This public use file is one in a series of event-level public use files drawn from the 2016 Medical Expenditure Panel Survey (MEPS) Household Component (HC). Released as an ASCII file with SAS, SPSS, and STATA program statements and in SAS transport format, the Hospital Inpatient Stays File provides detailed information on hospital inpatient stays. Data are gathered from a nationally representative sample of the civilian, noninstitutionalized population of the United States and can be used to make estimates of inpatient hospital stay utilizations and expenditures for calendar year 2016. Each record represents one household-reported inpatient hospital stay reported during the 2016 portion of round 3 and rounds 4 and 5 for Panel 20, as well as rounds 1, 2 and the 2016 portion of round 3 for Panel 21 of the survey (i.e., the rounds for the MEPS panels covering calendar year 2016). The Hospital Inpatient Stays Public Use Data File is an event-level data file containing characteristics associated with the hospital inpatient stay event such as: the date of the hospital inpatient stay, reason for the stay, types of services received, whether or not medicines were prescribed, and imputed expenditure data.
