OMOP Requirements
The Cohort Discovery Service operates on data mapped to the OMOP Common Data Model (CDM). This section defines the minimum set of OMOP fields that must be populated for your data to be discoverable.
What is OMOP?
OMOP (Observational Medical Outcomes Partnership) CDM is a global standard for observational health data. It is patient-centric, tabular, extendable, built for analytics, and has a relational design. For background, see the OHDSI OMOP CDM documentation.
