Researchers examined 91 C-CDA samples from 21 different EHRs. They used automated tools and manual inspections to find discrepancies and possible errors, and spoke with the EHR vendors to better understand the vendors’ interpretations of the 2014 Edition C-CDA requirements.
The researchers found 615 errors and variations in how data was expressed across the 91 C-CDA documents. They conclude the current heterogeneity among EHR’s C-CDA is currently limiting interoperability efforts, and true interoperability would require clarifying and standardizing the C-CDA requirements.
