In the 2021 PIONEER study-a-thon, the cohort definitions were designed on the big claims (MDCR, MDCD) and ehr (CPRD) datasets. This made that they were not in all the cases applicable directly on the study data. e.g. in one of the study datasets the biopsy measurements were recorded, but not the procedure of taking a biopsy. The latter was needed for the cohort definition.
Define study variables as being clinical events in the hospital. e.g. capture a biopt result also as a biopsy procedure (#30), but also other implicit events like blood sample taken.
