Name two interoperability standards used in health informatics and briefly state what they define.

• A. HL7 FHIR defines data exchange formats and APIs; SNOMED CT provides standardized clinical terminology.
• B. SNOMED CT defines data exchange formats; HL7 FHIR provides standardized clinical terminology.
• C. HL7 FHIR defines imaging formats; SNOMED CT defines network protocols.
• D. DICOM defines data exchange formats; HL7 FHIR provides standardized clinical terminology.

Answer: (A)

Interoperability in health informatics rests on two complementary pieces: how data is structured and exchanged, and how the clinical meaning of that data is represented. HL7 FHIR focuses on data exchange formats and APIs. It defines reusable data structures called resources (like Patient, Observation, etc.) and standard ways to access them via APIs, often using RESTful, JSON, or XML methods. This provides a consistent way for different systems to share and retrieve health information. SNOMED CT, on the other hand, provides standardized clinical terminology. It assigns codes and detailed concepts to medical ideas, with defined relationships between them, so clinicians and systems can speak a common language. This semantic consistency is what lets different systems interpret the meaning of data in the same way, even if they come from different vendors or settings. So the best pairing is the one that assigns data exchange formats and APIs to HL7 FHIR and standardized clinical terminology to SNOMED CT. The other options mix up these roles: HL7 FHIR is not about imaging formats, SNOMED CT is not a data-exchange format, and DICOM handles imaging data while HL7 FHIR is not a terminology standard.
