Health Data and Interoperability

OMOP CDM, HL7 FHIR, and SNOMED CT are the interoperability standards connecting hospital clinical data warehouses such as EDS AP-HP, national health data platforms such as Health Data Hub and SNDS, and the European EHDS. The OMOP vocabulary draws on ICD-10, LOINC, RxNorm, and CCAM as source terminologies. OMOP CDM is maintained by OHDSI and promoted by BBMRI-ERIC for cross-biobank data standardisation across Europe.
