Interoperability is one of the most critical issues facing the health care industry today. A universal exchange language is needed to assist health care providers in sharing health information in order to coordinate diagnosis and treatment, while maintaining privacy and security of personal data. Health Information Exchanges (HIE) allow for the movement of clinical data between disparate systems; they enable providers to electronically share health records through a network. This presentation provides an overview of HIE and the Meaningful Use requirement related to the exchange of clinical information as well as information about standards of exchange and the recommended "next steps" for providers.
