CommonWell leverages existing standards that members use to enable scalable, secure and reliable interoperability. Our service provider has built access to the services using the incumbent IHE standards (e.g., PIX for patient identity, XCA and XDS.b for locating and retrieving patient data) as well as the more modern HL7 FHIR-based standards (i.e., RESTful interfaces, such as the IHE MHD profile), thus allowing members to choose their preferred approach to connect to the network.
