IHE - Mobile Access to Health Documents

The IHE Mobile Access to Health Documents (MHD) includes support for PUSH based exchanges. This functionality is very similar to XDR, but uses FHIR.  see IHE publication -- https://profiles.ihe.net/ITI/HIE-Whitepaper/index.html#:~:text=the%20three%20models.-,3.1%20Push,-3.1.1%20Cross-Enterprise The MHD Profile provides a point-to-point method of sending documents to a specific recipient. It leverages common principles described in Section 2. It sends documents and metadata using FHIR Rest push to deliver one or more documents to a Document Recipient. The typical use case for MHD in this mode is when documents are known to be needed by a recipient. Such as a patient referral in the use case given in XDR. In addition the MHD can be used as an push API to a system that ultimately delivers the content. For example diagrammed below is MHD initiating a push to an Intermediary. In this use case the MHD push request could be handled by the intermediary that further pushes the content using XDR or an e-mail carrying XDM (e.g., the Direct Project). On the recipient side (not shown in the diagram) the MHD could be used by an intermediary to forward a XDR or XDM push content. MHD (not shown in the diagram) could also be used on the recipient side as a query/retrieve where the intermediary has cached content addressed to that recipient. This Intermediary is an example of a Direct Project HISP with the added functionality provided by MHD, enabling FHIR based push with end-to-end interoperability between three different transport stacks in MHD, XDR, and e-mail XDM.
