Green CDA: The missing link in EHR interoperability?

Date: Mar 31, 2011

The Clinical Document Architecture (CDA) data standard, which is based on the extensible markup language, or XML, is used in many electronic health record (EHR) systems. Health Level 7 International has developed a lightweight version known as the HL7 Green CDA standard. Although the CDA can represent any aspect of the EHR system for any purpose, at least in principle, the Green CDA standard tries to be simpler than the CDA, so it requires less computing power and is more human-readable.

At the Healthcare Information and Management Systems Society's HIMSS 2011 conference, we caught up with Dr. Bob Dolin, chairman of the HL7 board of directors. Here he explains the new data standard's significance and tells us what's new. In addition, he gives us an exclusive scoop on an alternative name for Green CDA that was left on the cutting room floor.
