Healtheway, the new private-sector entity that operates the eHealth Exchange (successor to the Nationwide Health Information Network or NwHIN Exchange), has partnered with the EHR/HIE Interoperability Work Group to implement standards that will make it easier to exchange health information. The Interoperability Work Group (IWG), led by the New York eHealth Collaborative (NYeHC), is a consortium of 15 states, 19 EHR vendors, and 18 HIE vendors that has been developing implementation guides for interoperability since February 2011. IWG and Healtheway have now selected the Certification Commission on Health Information Technology (CCHIT) to perform the testing and certification of EHRs and HIEs, as well as of providers that wish to connect with the eHealth Exchange.
