Learn how HL7 messages and FHIR resources support healthcare information exchange. Practice resource mapping, profile validation, terminology checks, and author
Last reviewed: 2026-10-03
Healthcare interoperability combines structured information with an agreed exchange contract. FHIR defines resources such as Patient and Observation, while implementation guides and profiles constrain how those resources are used. HL7 v2 messages and FHIR resources are different representations; a migration needs explicit mappings rather than a format rename.
Start with synthetic records and the receiving system's declared FHIR version, profiles, and terminology bindings. FHIR is not itself a security protocol. Authentication, authorization, secure transport, and auditing belong in the integration design alongside resource validation.
No. Version, profiles, terminology, supported operations, and access arrangements vary. Confirm the receiving system's contract and test it with approved sample data.
