This file is one in a series of public use event files from the 2017 Medical Expenditure Panel Survey Household Component (MEPS HC) and Medical Provider Component (MPC). Released as an ASCII data file and SAS transport file (with SAS, STATA, and SPSS user statements) this public use file provides detailed information on household-reported prescribed medicines for a nationally representative sample of the civilian noninstitutionalized population of the United States and can be used to make estimates of prescribed medicine utilization and expenditures for calendar year 2017. Each record represents one household-reported prescribed medicine that was purchased during calendar year 2017. These data were collected during the 2017 portion of Round 3 and Rounds 4 and 5 for Panel 21, as well as Rounds 1, 2 and the 2017 portion of Round 3 for Panel 22 of the MEPS HC. Each record on this event file represents a unique prescribed medicine event; that is, a prescribed medicine reported as being purchased or otherwise obtained by the household respondent, and includes the following: an identifier for each unique prescribed medicine; detailed characteristics associated with the event (e.g., national drug code (NDC), medicine name, etc.); selected Multum Lexicon variables; the date on which the person first used the medicine; total expenditure and sources of payments; types of pharmacies that filled the household's prescriptions; and a full-year person level weight.
