Hi Vhrao, ASTM manages CCR.
Google Health supports a SMALL SUBSET of the CCR specification - Google Health does not support anything related to CDA, CCD or HL7 - and one might be thankful of that as it is quite complex and in the domain of EMR system vendors who sell things starting at $250,000.00 Hl7.org manages CDA http://www.hl7.org/ CCD (Continuity of Care Document), an ANSI standard approved in 2007, is built on CDA elements by using a detailed set of constraints. HL7’s Clinical Document Architecture (CDA) stores or moves clinical documents between medical systems. Documents are things like discharge summaries, progress notes, history and physical reports, prior lab results, etc. The CDA uses XML for encoding of the documents and breaks down the document in generic, unnamed, and non-templated sections. HL7’s CDA defines a very generic structure for delivering “any document” between systems. What is missing in the CDA standard proper is a listing of the sections of that document. That is, a template of the expected sections that will appear in a given type of document. For example, on a history and physical document, sections could be named Current Medications, Prior Immunizations, Social History, etc. Ignoring the political or technical motivation, an independent group at the ASTM was formed and worked to define an XML standard for moving documents between systems. That is what CCR is (some think "was" but I am not going toi get into that here... Initially, this standard was unrelated to HL7’s CDA standard. It is fair to say the standards competed for mind share and each expressed a different integration philosophy. In later efforts, the two standards groups agreed to effectively make the standards compatible with each other. The Memorandum of Understanding (MOU) between HL7 and ASTM says that they will “harmonize” the two competing standards. That’s a fancy way of saying they will play nicely. Some like to describe the CCR as a specialization of the CDA. That is, the CCR provides a template of the expected sections that will be provided in CDA format. This CCR “content profile” is a tightly controlled list of document sections answering the “What major bits of data will be sent?” question. The CDA, then, is the structure of how the document will be formatted in XML. There are many many issues... Some of us are trying to play nice in this complex sandbox with PDF http://www.myhealthcarestuff.com/cdapdf.html hope this helps Michael Jahn Jahn & Associates PDF Conversion Specialist 1824 North Garvin Avenue Simi Valley California 93065 Office: (805) 527 8130 Cell: (805) 217 6741 Email: [email protected] Skype: michaelejahn Twitter: http://twitter.com/michaelejahn Blog: http://michaelejahn.blogspot.com/ On Mon, Nov 9, 2009 at 1:49 PM, vhrao <[email protected]> wrote: > > I have been reading up on CCR and CCD.
