FHIR can be used as a stand-alone data exchange standard.

• A. True
• B. False
• C. Sometimes
• D. Not at all

Answer: (B)

FHIR provides a modern, RESTful way to structure and exchange health data, but it is not a stand-alone data exchange standard. To achieve true interoperability, you need additional pieces beyond the core resources and API:

• Profiles and implementation guides to constrain resources so different systems interpret data consistently.

• Standard terminologies and value sets, with terminology services, to ensure shared meaning for codes (for example, SNOMED CT, LOINC).

• Security and identity layer requirements (authentication, authorization, consent management) such as OAuth2 and SMART on FHIR.

• Governance around data privacy, access control, and patient consent.

• Mappings or bridges to legacy or other formats (like HL7 v2 or CDA) when integrating with older systems.

Because these elements are typically necessary, FHIR alone does not suffice as a stand-alone exchange standard.
