• In the U.S.A. there is a growing push to adopt HL7 CDA as one vehicle for helping to achieving “Meaningful Use” under President Obama’s stimulus package .
  • In Australia, a number of projects have tried to standardise the content of hospital discharge summaries, particularly around good medication management principles and the inclusion of important clinical information to support ongoing care.
  • We know it is not difficult to format this type of discharge summary data into the XHTML narrative parts of a CDA document. Yet there is no evidence that fully coded entries, i.e. HL7’s solution to semantic interoperability can work in practice. This challenge is designed to test this, with a simple, real world example from early 2006.
  • The HealthBase CDA Challenge is designed to see if, and how well HL7 CDA R2 can meet the needs of health information exchange.
  • Such a capability is a first step to building quality decision support or a coherent EHR system. If this basic task can’t be achieved, then HL7 CDA’s claim as a practical mechanism for supporting effective information interoperability must surely be in doubt.
