Clinical Document Architecture
CDA (Clinical Document Architecture) conveys appropriate information to appropriate person. It is not only a document but also an architecture. CDA usually include text, sounds, images and other multimedia content. There exists variability in clinical notes, degree of semantic coding, use of standard healthcare terminologies and etc. Thus, it becomes difficult to store and exchange documents. CDA standard takes a step closer towards solving these variability. The CDA is a document markup standard that specifies structure and semantics of ‘clinical document’. The CDA is a part of HL7 Version 3 family of standards. The encoding is done in Extensible Markup Language (XML).A clinical document will exist as unchanged for a stipulated time period
