tblOVERLAP - Cross-cohort identification

holds information on the patient's participation in other cohorts

Core fields

Note: Fields marked bold form the unique identifier for a record of the table.

  • PATIENT: Code to identify patient (Cohort Patient ID)
  • COHORT: Code/name of the cohort
  • PAT_OTH: Unique patient identifier in other cohorts
  • COH_OTH: Name of the cohort

Patients of an “original”-cohort who also participate in a “super”-cohort should be analysed within the “original”-cohort only. To suppress these patients from the datasets of the “super”-cohorts the identifier used in the “super”-cohort is needed. It is suggested that “original”-cohorts report id’s from the “super”-cohorts, since the “super”-cohorts might not even know the other ID’s. Often this information is only available at centre level.

A record should be present for each cohort that the patient is participating in (apart from it’s own “original”-cohort).
