HL7 FHIR
HL7 Fast Healthcare Interoperability Resources (FHIR) R4
Scope
FHIR is the modern REST/JSON standard for healthcare data exchange. In the US, ONC's Cures Act rule mandates FHIR R4 APIs for certified EHRs, using the USCDI dataset. FHIR is what the smart room usually speaks to the outside world after HL7 v2 speaks to the bedside.
Where it applies in the room
- EHR patient-facing and provider-facing APIs
- Observation, Device, Encounter, and Patient resources
- SMART-on-FHIR app launches inside the EHR
