Project Introduction

FHIR to OMOP

This project is a collaboration between the OHDSI (Observational Health Data Sciences and Informatics) community and HL7’s Vulcan FHIR Accelerator, aimed at improving how health data can be shared and analyzed for research and better care.

What is OHDSI?

OHDSI is a global open-science community that develops methods, tools, and standards for generating real-world evidence from health data, with the OMOP Common Data Model (CDM) as its foundation. OMOP allows diverse health data to be standardized, enabling large-scale research and reproducible results.

HL7 FHIR (Fast Healthcare Interoperability Resources) is today’s most widely adopted health data exchange standard, designed to make clinical data easily shareable across systems. While OMOP is optimized for research analytics, FHIR is optimized for interoperability and exchange.

This project bridges the two: it provides a standardized approach to transform data from FHIR into OMOP CDM. By doing so, organizations can use both FHIR’s interoperability strengths and OHDSI’s powerful research methods. The result is higher-quality, more consistent, and more scalable use of health data for research, policy, and care—accelerating the impact of real-world evidence on health decisions worldwide.
