Which data exchange mechanism does Care Everywhere primarily rely on for structured clinical summaries?

• A. CCDA-based document exchange, with HL7 transport used for routing in the background.
• B. Direct SQL database replication.
• C. Emailing PDFs of patient records.
• D. SOAP web services for each data type.

Answer: (A)

Care Everywhere primarily moves standardized clinical summaries by exchanging CCDA documents. A CCDA document packages structured data—demographics, problems, medications, allergies, labs, encounters—into one interoperable format that many EHRs can read and display. The routing and delivery of these documents between systems are handled by HL7 transport in the background, which provides the secure, reliable path for moving the data.

This approach beats the alternative ideas because copying entire databases (SQL replication) isn’t designed for interoperable, semantically rich clinical sharing and raises privacy concerns; sending PDFs by email loses structure and searchability; and using SOAP web services for each data type would require multiple, separate services and isn’t how Care Everywhere standardizes and routes data. The CCDA document, with HL7 transport, offers a single, consistent method for sharing structured clinical summaries across systems.
