The FHIR Project at Georgia Tech

OMOPonFHIR server is a Georgia Tech’s Fast Healthcare Interoperability Resources (FHIR) project to build a FHIR resource on Observational Medical Outcomes Partnership (OMOP) common data model (CDM). It is built on top of Hapi Fhir libraries. Currently, OMOPonFHIR support DSTU2 and STU3.

The key component of GT-FHIR is a data access layer that has been modified to support any database schema. The component allows OMOP CDM to be deployed as a backend database. FHIR resources from/to OMOP CDM mapping is done at the gt-fhir-entities. However, as FHIR and OMOP CDM cannot be mapped one-to-one, some of data elements are set statically. Some mappings require multiple FHIR entity-jpa classes to support bidirectional mappings.

OMOP to FHIR or FHIR to OMOP Mapping information can be found at OHDSI FHIR Workgroup wiki page.

We are constantly working on mapping new concepts and adding to new features. Pull requests are welcome! For more details on source codes, visit OMOPonFHIR Project Github.

Current OMOPonFHIR Version

Snapshot of OMOPonFHIR: There is a public OMOPonFHIR site that shows the latest snapshot. This runs with HAPI-FHIR’s UI Testpage running over Synpuff data source in OMOP v5. OMOPonFHIR Snapshot Server

SMART on FHIR: OMOPonFHIR is also equipped to support SMART on FHIR. OMOPonFHIR server has built-in services to support SMART on FHIR Authorization flow. This allows to simulate EHR-launching or stand-alone launching. The github page has a link to the smart on fhir launcher.

[Deployment scripts] OMOPonFHIR includes docker composer, which helps deploying the server in the docker container.
