synthea

Generate synthetic FHIR data from PheKB phenotypes by running the full pipeline command, which creates Synthea modules, produces synthetic patients, and loads them directly into a FHIR server for testing.

Create distinct positive and control cohorts for QA validation by generating synthetic patient data from phenotype modules. This approach produces separate cohorts to validate query accuracy and verify system behavior across test environments.

Yes, a running FHIR server at http://localhost:5826/r4 is required to load the generated synthetic patient data. The pipeline commands expect this endpoint to be active to successfully import the synthetic FHIR records.

Reproduce synthetic patient cohorts for multiple phenotypes by leveraging reusable GMF-based module templates and existing phenotype data. This approach consistently regenerates synthetic cohorts across different testing scenarios.

Place existing Synthea modules under synthea/modules/custom and phenotype data under test-cases/phekb. These specific directory locations are required for the pipeline to correctly read and process the generation inputs.

The pipeline provides create-module, generate, load, and full commands to manage the synthetic FHIR data workflow. These commands handle everything from phenotype module creation to FHIR server loading end-to-end.
