Carequality Interoperability Framework

Carequality is a multi-stakeholder initiative that maintains and operates a trusted exchange framework and common agreement governing health information exchange between and among health information networks on a nationwide scale.  The Carequality Interoperability Framework is a trusted exchange framework that consists of a common trust agreement, policy requirements, technical specifications, and governance processes that together make it possible for healthcare to replicate the success other industries have achieved in breaking down barriers between many networks, programs, and platforms. The Carequality Interoperability Framework is supported by Carequality Inc., an independent non-profit organization.
