In 2007, as the National Healthcare Safety Network (NHSN) was gearing up to collect information on healthcare associated infections (HAIs), they needed a mechanism to pull information captured in local infection control applications and EHRs without redundant data entry. The prevalent standards for data sharing could not easily model the reports and were not compatible…

Clinical Documents were never meant to hold 10 pounds of coded data. CDA is a 5-pound bag, containing the actual words, either written directly by a clinician or spoken and transcribed, with the minimal coding necessary for the use case.

  A solitary Wild CDA has left its pride. We can only presume it is searching for a mate by its extravagantly complex header and the swish of its long tail of codes. However, research tells us that while a long code tail is nice to have, it is the mating call of the CDA,…

  It has been weeks since our last episode. Frankly, the sight of that genetically mutated Wild-CDA/North-American-XHTML hybrid left my team so repulsed that many could not continue. But after discussing the importance of this work, and a few crew changes, we are back in the field.   And we are documenting something never seen…

  During our last episode, we stumbled upon a wild CDA lying dead in the grass. Not wanting to pass up such an opportunity, we decided to dissect the beast to uncover the cause of death. The immediate cause turned out to be a malformed end tag that resulted in catastrophic system failure.   Further…

  Move in closer now…do you see that? It’s a wild CDA lying motionless in the grass. Surely it’s waiting for prey to…wait, it’s not moving – something’s wrong…   Ah, this one was dead when we got here.   A fair number of wild CDAs suffer from basic XML issues. This means they are…

The HL7 Consolidated Clinical Document Architecture (C-CDA) Release 2 ballot received an unprecedented 1,000+ comments. A number of those comments include proposals to tighten various constraints within the document.
