Description

For all event-medication-round link records, MEPSLINKIDK uniquely identifies medication-round records across MEPS panels. MEPSLINKIDK is created for 1996-2017 by combining PANELK, LINKIDK, and a 2-digit event type number ("03" for prescribed medicines, "02" for other medical expenses, and "01" for all other event types). IPUMS MEPS staff create MEPSLINKIDK to provide a single, universal linking key for linking across MEPS event and medication-round records.

Beginning in 2018, AHRQ modified the identifiers DUIDK and DUPERSIDK (which combines DUIDK with PIDK) on the original MEPS data files to append information about PANELK to the first two columns. AHRQ also added a 2-digit event type number beginning in 2018. MEPSLINKIDK is the same as LINKIDK for 2018 forward.

Event-Medication-Round Record Linking
The event, medication-round, and medication-round fill records can be joined together by using the event-medication-round link records. MEPSLINKIDK is on the event-medication-round link record and is the same as MEPSLINKIDM on the medication-round record and MEPSLINKIDF on the medication-round fill record.

See our user note for more details on how to join the different record types and an overview of the event, medical conditions, and prescribed medicines variables, how those variables are offered through IPUMS MEPS, and general considerations to keep in mind when conducting analyses using these variables.

MEPSLINKIDK is a 16-character string variable.
