The Common Data Model Harmonization (CDMH) project is led by FDA in collaboration with NIH and HHS/Office of the National Coordinator for Health Information Technology (ONC). The goal of this project is to harmonize 4 CDMs (Sentinel, OMOP, i2b2/ACT and PCORnet) and be able to leverage open, consensus-based standards (e.g. HL7 FHIR and Clinical Data Interchange Standards Consortium (CDISC) standards). In this project, we leveraged the Biomedical Research Integrated Domain Group (BRIDG) as the intermediary model and mapped the 4 CDMs to the BRIDG model.
The CDMH data elements have been registered at National Cancer Institute (NCI) Cancer Data Standards Registry and Repository (caDSR) and available at:
