Common Healthcare Data Interoperability Project

The Common Healthcare Data Interoperability Project is a collaboration between The Pew Charitable Trusts (Pew) and the Duke Clinical Research Institute (DCRI) to advance interoperability among electronic health records and registries. Working with Pew, DCRI seeks to:
•	identify the clinical concepts that appear frequently across multiple registries, 
•	determine how those concepts should be best represented as standardized common data elements (CDEs), and 
•	create an implementation guide for database developers so that registries and health information technology developers can implement the standardized CDEs with the least amount of effort.

Rather than create a new data standard, this project will rely on predicate content included in the Office of the National Coordinator for Health Information Technology 2018 US Core Data for Interoperability, Health Level 7 Fast Healthcare Interoperability Resources profiles and resources, and reference the work of standards development organizations, such as LOINC and other groups that have addressed aspects of the data interoperability problem.
