Health information exchange (HIE) collectives and networks-of-networks including eHealth Exchange, CommonWell, and Surescripts help promote secure health data exchange across healthcare facilities nationwide.
Specifically, many networks-of-networks have been successful in promoting standardization through the use of the Carequality technical and legal framework. In 2016, CommonWell signed an agreement with Carequality to implement the Carequality Interoperability Framework to further promote interoperability. As part of the agreement, CommonWell and The Sequoia Project agreed to carry out the interoperability and health data exchange activities necessary to create a Carequality-compliant CommonWell alliance. Additionally, the two networks agreed to collaborate in the future.
