In the context of a Health Information Exchange, which statement best describes standards?

• A. Privacy protections
• B. Data formats and interoperability standards
• C. User authentication
• D. Funding

Answer: (B)

Standards specify how data should be formatted, coded, and exchanged in a Health Information Exchange so different systems can understand one another. They cover data formats (for example, HL7 and FHIR messages, CDA documents), code sets (like LOINC, SNOMED CT, ICD), and document structures that enable both syntactic and semantic interoperability. This ensures that when data moves from one organization to another, the meaning and context remain intact and usable in the receiving system.

Privacy protections, user authentication, and funding are important aspects of health information sharing, but they address governance, security, and resources rather than the technical specifications that enable data to be exchanged consistently.
