Jay mentioned on the call this week that we have two types of Enrollment (insurance-based and residency-based) for Mini-Sentinel. In general, enrollment records are used to help identify the time periods during which we should have data for a given patient if they sought care.
We don't know what this means for markets with competition (eastern and western Wisconsin) if we expand our population beyond Mini-Sentinel. May be an interesting question for PCORnet to address-especially for CDRNs with a high probability of overlap (CaPRICORN, etc.) Residency: We have two geographically defined Marshfield Epidemiologic Study Areas (north and central) where we have confirmed health care coverage. These are curated cohorts. For this residency-based logic, we pull from the MESA addresses tables, which has start and end dates for when the patient lived at a certain address. Insurance Coverage: Eligibility dates pulled directly from our insurance plan's tables. If the patient received care, we should have the claims. Summary of the Mini-Sentinel code: * Extract all MESA residency records during the study period (January of 1992 through the end of the most recent completed month, i.e. if run currently it would be through the end of August 2014). * Format and standardize MESA residency data for later processing. This includes identifying only residency periods that overlap the study period, and making sure that residency does not extend past death. * Extract all SHP eligibility periods during the study time period. * Format and standardize SHP eligibility data for later processing. This includes identifying only eligibility periods that overlap the study period, and making sure that eligibility does not extend past death. * Merge together SHP and MESA enrollment, and combine and condense periods for each MHN to determine continuous membership. * Merge together all overlapping enrollment periods, ignoring gaps of the length specified in the driver program (32 days) and flag enrollment periods as MESA only, SHP Only, or Both.
