Which data exchange standard underpins Care Everywhere for structured clinical data?

• A. DICOM imaging files only.
• B. CCDA-based documents and HL7-based payloads, with HL7 transport; FHIR may be supported in newer configurations.
• C. HL7 v2 messages without CCDA.
• D. FHIR only, no CCDA.

Answer: (D)

Care Everywhere exchanges structured clinical data using a standardized clinical document format paired with a messaging/transport layer. The backbone is CCDA-based documents, which provide a consistent, machine-readable summary of patient data, carried over HL7-based payloads and transported through an HL7 transport mechanism. DICOM is specific to imaging, so it doesn’t cover the broader structured clinical data shared in Care Everywhere. HL7 v2 messages without a CCDA lack the standardized clinical document structure that many exchanges rely on. FHIR may appear in newer configurations, but the established approach centers on CCDA documents with HL7 transport, with FHIR as a potential addition rather than the sole underpinning.
