The Sequoia Project

The Sequoia Project is a neutral, stakeholder-driven, public-private collaborative whose sole mission is advancing secure, trusted, interoperable health data sharing across the U.S. We support multiple, independently-governed initiatives, such as the eHealth Exchange, the largest data sharing network of its kind in the US, and Carequality, which facilitates consensus on a standardized, national-level interoperability framework to link all data sharing networks from across the entire healthcare ecosystem. The eHealth Exchange network and Carequality are now independent non-profit organizations. The RSNA Image Share Validation Program is an interoperability testing program to enable seamless sharing of medical images. In 2019, Interoperability Matters is a new cooperative of private sector and government stakeholders convening to prioritize and solve discrete barriers to exchange, such as information blocking. 
The Sequoia Project also champions interoperability, building upon the successes across industry and government and working proactively to identify and systematically address known impediments to interoperability, such as patient matching. 
The Sequoia Project and its initiatives implement federally-recognized and national interoperability standards throughout our work.  We firmly believe in the importance of interoperability standards and advocate for open approaches to interoperability that are built upon standards that work nationwide.   In addition, The Sequoia Project, in conjunction with HL7's Argonaut Project, is pioneering implementation of FHIR via its initiatives, such as a FHIR-based provider directory work.
