HL7/FHIR Test Data Generator Released: Supporting Interface Development

Details

This tool provides synthetic data for both HL7 v2 and FHIR resources (including Patient, Encounter, Observation, etc.), targeting interface developers and QA testers. Users can select a message type or scenario to simulate fictional patient information and clinical records. The generated data is explicitly stated for demonstration and testing purposes only, and cannot be used as actual clinical records or for compliance validation. A key technical feature is that the FHIR output is provided in JSON format, enabling testing via Bundle structures that link multiple resources. While the tool lacks automatic validation against local implementation guides or vendor-specific profiles, it serves as a useful resource for sample provision during early interface development and mapping workshops. In Japanese healthcare IT environments, preparing test data for system interoperability (e.g., between EMR and billing systems) is a critical challenge. Synthetic data generation tools like this offer a valuable technical approach for designing interfaces and conducting regression testing efficiently while respecting patient privacy concerns.
