For all events, EVNTID is an AHRQ-generated identifier that begins with DUPERSIDE. From 1996-2017 EVNTID uniquely identifiers event records within a panel. To uniquely identify records across all MEPS panels, please see MEPSEVNTID. Beginning in 2018, EVNTID uniquely identifies records across panels due to changes in the construction of DUPERSIDE to add PANELE to the first two digits of the DUPERSIDE identifier and the addition of a 2-digit event type number.
EVNTID is on the event record (see RECTYPE for more details on the different record types in IPUMS MEPS). Variables offered on the event record through IPUMS MEPS are derived from the dental visits, other medical expenses, hospital inpatient stays, emergency room visits, outpatient visits, office-based medical provider visits, and home health event files provided by AHRQ. Please see our overview of the event, medical conditions, and prescribed medicines variables, including how those variables are offered through IPUMS MEPS, and general considerations to keep in mind when conducting analyses using these variables.
From 1996-2017, EVNTID is a 12-character string variable. Beginning in 2018, EVNTID is a 16-character string variable.
