The Sequoia Project, formerly known as Healtheway, was established in 2012 when the Office of the National Coordinator for Health IT (HHS) transitioned the Nationwide Health Information Network (NHIN), now known as the eHealth Exchange, to the private sector. The Sequoia Project is a non-profit 501c3 chartered to advance implementation of secure, interoperable nationwide health information exchange. An independent and neutral advocate for interoperability, The Sequoia Project supports multiple, independent health IT interoperability initiatives, most notably: the eHealth Exchange, the nation’s largest health data sharing network of participants who share information under a common trust framework and a common set of rules; and Carequality, a public-private collaborative effort to build consensus among existing data sharing networks regarding technical specifications and best practices, much like the telecommunications industry did for linking cell phone networks.
