Which statement best describes interoperability in health IT?

• A. It is the ability of different EHR systems to securely exchange and interpret shared data.
• B. It means all data is stored in a single system.
• C. It refers only to cybersecurity of medical devices.
• D. It ensures that physicians share the same user interface.

Answer: (A)

Interoperability in health IT means the ability of different EHR systems to securely exchange and interpret shared data. Secure exchange involves protecting privacy and data integrity during transfer through appropriate security measures, while interpretation means the receiving system can understand and use the data correctly, which relies on standardized formats and codes (for example, HL7/FHIR, SNOMED CT, LOINC, RxNorm). This combination lets clinicians access a complete, actionable view of a patient across settings, enabling coordinated care even when data originate from different systems. The other statements miss this core idea: centralizing data in one system isn’t about exchanging and understanding data between systems; cybersecurity of devices is about security rather than interchange; and sharing the same user interface addresses presentation, not data compatibility or meaning.
