What is OMOPonFHIR?

OMOPonFHIR, also known as Georgia Tech’s Fast Healthcare Interoperability Resources (FHIR) and Observational Medical Outcomes Partnership (OMOP) common data model (CDM) mapping platform, supports various mapping combinations between versions of FHIR and OMOP CDM.

OMOPonFHIR supports bidirectional read and write capabilities for FHIR versions DSTU2, STU3, R4 and OMOP CDM v.5.3.1 and v6.0.

The platform is Java based, built on top of HAPI FHIR libraries. It is database agnostic, due to the fact that SQLRender has enabled for custom architectural workflows. OMOPonFHIR components have been containerized to simplify deployment in both native and cloud environmnents.

OMOPonFHIR has the capability to work with other open source tools and technologies such as OHDSI's Atlas, SMART on FHIR, Clinical Quality Language (CQL) and so on.

OMOP to FHIR

OMOPonFHIR allows the retrieval of data stored in the OMOP CDM relational schema as FHIR Resources. Users may provide standard FHIR queries to the server which are translated into SQL queries to be performed on the OMOP CDM database. After being read, the data is passed through a mapping layer and converted into FHIR Resources which are provided to the user. Combined with OMOPonFHIR’s SMARTonFHIR capabilities, this allows users a powerful way to work with their OMOP CDM data in which they could never before.

FHIR to OMOP

In addition to retrieval of OMOP CDM data, when running with write permissions OMOPonFHIR allows users to post most FHIR Resources to the server and have them passed through the mapping layer and then written to the OMOP CDM database. In addition to allowing standard FHIR retrieval of their posted resources, this enables users to utilize powerful research tools built around the OMOP CDM schema with their clinical data available in FHIR.
