Proposal for precise modeling of entities in the U.S. Core Data for Interoperability

Abstract

The USCDI V1 is a landmark specification of core clinical data that will be made available by providers and payers for nationwide exchange. Recognizing USCDI's significant promise for directing future interoperability efforts, we seek to improve its foundation for continued expansion. In particular, we believe that improving the clarity of USCDI entity definitions are necessary for the industry to interpret them consistently. We seek to add precision to their specifications to enable a principled approach for users to understand, implement, extend, and refine them with future submissions for new USCDI content.
