The CDA is the instrument of interoperability in healthcare. It’s the format clinicians use to exchange healthcare data. The Office of the National Coordinator for Health Information Technology (ONC) requires its use for EHR certification.
I believe the CDA is severely flawed, if not outright dangerous. What “you” see is not always the data “they” get.
The CDA consists of two components, the “human readable” part, and the “data” part. These two parts are almost totally disjoint. The clinician only sees the human readable part. She almost never sees the “data” part. I believe errors are going undetected.
What do you call a banker that sends out a financial transaction without first eyeballing the actual data? Unemployed.
I created a utility that will display the “data” part of the CDA in a human readable format. Its purpose is to encourage you to compare the “data” part with your “human readable” part. We should be logging these errors before someone dies from one. This tool is free, just click on Tools. Of course, you must only use this tool with a de-identified CDA.
