At the end of the call we briefly started a discussion of the role of a unique ID for health and the fundamental importance of these to a successful care delivery network. Last year (2019), the OpenHIE community lead the development of an IHE Profile that addresses this important topic.
Details about the workflows needed to ensure the correctness of establishing the unique enterprise ID for a subject of care as part of saving health data related to that person are detailed in the Mobile Health Document Sharing (MHDS) Profile. Information about MHDS can be found here: https://wiki.ihe.net/index.php/Mobile_Health_Document_Sharing_(MHDS).
Both PMIR and MHDS are conformance-testable, FHIR-based profiles. They are part of a larger initiative (and a new IHE white paper) focused on how to engineer an entirely FHIR-based HIE. The IHE white paper will be published later in 2020 (and will include OpenHIE as an exemplar).
