Complete interoperability of centralized and federated EHRs is already in place.

Complete interoperability of centralized and federated EHRs is already in place.

• A. True
• B. False
• C. Partially
• D. Not yet

Answer: (B)

Interoperability means systems can exchange data and that the meaning of that data is preserved so it can be used effectively across different EHR architectures. Centralized EHRs store data in one location, while federated approaches keep data at its source but allow cross-organization access. While standards and networks are advancing—such as FHIR for data exchange and common vocabularies like SNOMED CT and LOINC—the reality is that complete, universal interoperability across all centralized and federated EHRs has not been achieved. There are persistent gaps in semantic alignment, patient identity matching, data quality, and governance, plus varying provider capabilities, vendor implementations, and regulatory constraints that prevent flawless, end-to-end interoperability in every setting. So the statement that complete interoperability is already in place is not accurate; progress exists, but the coexistence of centralized and federated systems is not yet fully seamless everywhere.
