FHIR StructureMaps: Enabling Bi‑Directional Data Transformation

FHIR INTEGRATION STANDARDS

Healthcare interoperability often sounds straightforward—move data reliably between systems—but real‑world integration is far more complex, with differing models, semantics, and concepts. In a recent project, we faced this challenge in a sector with no existing interoperability standard, relying instead on a widely adopted operational dataset as our domain model. To bridge the gap with FHIR, we used StructureMaps and the $transform operation, enabling clean, scalable, bi‑directional mapping. This allowed us to deliver a robust transformation layer without building yet another bespoke engine.
