communityLink connects multiple healthcare enterprises or groups of enterprises (called communities) into a larger network so clinical information can travel with the patient beyond the boundary of a single enterprise.
As a fully-featured IHE XCA Gateway, communityLink interfaces with local information systems in order to securely expose selected clinical content managed by these systems to remote healthcare enterprises. It also makes clinical information from the remote enterprises accessible to the local enterprise.
Many EMR vendors, including Epic and Cerner, support the XCA standard standard as a means of exchanging clinical information with external systems, enterprises, or communities of enterprises. Moreover, the Office on the National Coordinator (ONC) for Health Information Technology recommends XCA as a interoperability approach for exchanging clinical data between disparate EMR systems.
Leafsprout utilizes communityGateway internally as a way to bring external health records into its own echosystem, and to allow external systems/EMRs access its own content.
