When it was introduced in 2009, the goal of meaningful was to establish certification requirements for health IT. Then came the 21st Century Cures Act in 2016, which expanded on meaningful use to include enabling access to all electronically accessible health information across providers, patients, public health, registries and payers alike. Finally, on January 5, 2018, the Office of the National Coordinator released two draft documents: one that deals with the Trusted Exchange Framework Cooperative Agreement or TEFCA, which the 21st Century Cures Act directed ONC to develop as the guardrails for nationwide health information exchange. The other draft document, called the U.S. Core Data for Interoperability or USCDI, defines the “what” for health information exchange by laying out the data classes that are to be exchanged. In this episode of The Cerner Podcast, we’re joined by Dr. David McCallie, Cerner’s senior vice president of medical Informatics. He discusses some of the details surrounding TECFA and USCDI and gives his thoughts on what’s next on the path toward interoperability.
