The final formal proposal for changes to the HL7 Clinical Document Architecture standard was reviewed today. The HL7 Structured Documents Work Group (SDWG) has been reviewing formal proposals for the next release of CDA for over a year. CDA R2 is the standard that is used for most of the exchange of clinical information in the Meaningful Use requirements that were published in the Federal Register this week.
I am the publishing facilitator for the SDWG, so this means that I get to work on creating the new version of the standard. I worked on CDA R2 back when I was working for HL7, converting the word document into "publishing XML." The new version of the standard will be developed using the HL7 Publishing database. I have not used the publishing db in several years, so it will be interesting to see how the tool has changed over the years.
The enhancements in CDA R3 are based on the experience of implementers. CDA will also use HL7 Version 3 Datatypes Release 2, which will give us new functionality.
Here is a link to the list of suggested enhancements for CDA R3:
I'll post updates as we work through the process. I expect that we will ballot the new document early next year, and, hopefully, CDA R3 will become an approved standard sometime in 2011.
