FHIR

Sources and review notes

These links support definition-level research and do not establish the regulatory status, safety, or suitability of any product.

HL7 defines FHIR as a standard for electronic healthcare-information exchange built from resources, with CapabilityStatement artifacts describing exposed interfaces and StructureDefinition artifacts constraining resources for particular uses. HL7 publishes multiple FHIR releases and assigns individual artifacts maturity and standards-status levels; version compatibility and production readiness cannot be inferred from the word FHIR alone. The specification supports multiple exchange patterns, and using FHIR resources does not necessarily mean using its RESTful API. Buyers should verify the exact FHIR release, implementation guide and package version, profiles and extensions, resource elements and terminology bindings, search parameters and operations, read/write/subscription support, CapabilityStatement, authentication and authorization model, patient and provider identity, consent enforcement, provenance, pagination and rate limits, error responses, bulk and historical behavior, test endpoint, conformance testing and production monitoring. FHIR conformance does not by itself prove semantic agreement, complete or timely data, secure deployment, successful workflow integration, regulatory compliance, clinical safety or backward compatibility across non-normative content; those require use-case-specific testing and accountable review.
