CDA (clinical document architecture) is the most widely adopted implementation of HL7 v3. It is used for exchanging information in the form of documents. CDA has three levels: level 1 is a single human-readable document, level 2 can include multiple documents and level 3 can include structured information. Each CDA document has a common header and a variable body part. Templates are used to constrain the generic CDA model. The continuity of care document (CCD) is used to summarize a patients' health record. Consolidated CDA (C-CDA) is a harmonized set of templates for a variety of clinical documents.
