How is HL7 and CCD related?

The Continuity of Care Document (CCD) is built using HL7 Clinical Document Architecture (CDA) elements and contains data that is defined by the ASTM Continuity of Care Record (CCR). It is used to share summary information about the patient within the broader context of the personal health record.

What is HL7 CCD?

The HL7 Clinical Document Architecture (CDA) is a document markup standard that specifies the structure and semantics of clinical documents for the purpose of exchange. From the perspective of CDA, the CCR is a standardized data set that can be used to constrain CDA specifically for summary documents.

What is CDA FHIR?
