Technical Summary
The FHIR-to-OMOP Mapper is a specialized Extract, Transform, Load (ETL) utility designed to convert Electronic Health Record (EHR) data from the HL7 FHIR standard into the OHDSI OMOP Common Data Model format.
Key Capabilities
- Standardized Conversion: Automatically maps FHIR resources (like Patient, Condition, Observation, and MedicationRequest) to the corresponding OMOP tables (PERSON, CONDITION_OCCURRENCE, MEASUREMENT, and DRUG_EXPOSURE).
- Terminology Mapping: Integrates with standard vocabularies (SNOMED, RxNorm, LOINC) to ensure semantic consistency during the transformation process.
- Scalable ETL Pipeline: Can be deployed via Docker or Kubernetes to process large batches of FHIR bundles rapidly.
Usage in Healthcare
This tool is critical for organizations transitioning from operational EHR formats (FHIR) to analytical research formats (OMOP). It allows hospitals to run standardized observational studies and federated learning models on data originally collected for direct patient care.
