This page holds the status of the revision of the Mobile access to Health Documents (MHD) profile.
The MHD profile was created in 2012 as a simple RESTful API to the Document Sharing environment (XDS, XCA, XDR, and XDM). This was at the same time that HL7 initiated their FHIR standard using REST. The profile, while in "Trial Implementation", inspired the creation of the necessary Resources within the HL7 FHIR standard. HL7 FHIR is now in "Draft Standard for Trial Use" (DSTU), so IHE is adjusting the MHD profile to utilize HL7 FHIR.
After the completion of FHIR DSTU1, IHE updated MHD (2014-2015 work item), informally referred to as MHD2, produced a new "Trial Implementation" version. This work item also produced a number of change proposals upon the FHIR specification.
Detailed Mapping of Document Sharing (e.g. XDS) to MHD (FHIR) can be found at MHD-rev2-vol-3. This material will continue to evolve over 2014, so is only published on the Wiki. Implementers will find additional guidance and examples at MHD Implementation Guide
These FHIR change proposals have now resulted in FHIR DSTU2. The FHIR DSTU2 specification has indicated that the DocumentReference, DocumentManifest, and other resources used by MHD are to be considered Mature and 'Frozen'. This is an indication by HL7 that there is no expected major changes to these Resources, but as DSTU there still could be changes. IHE will now update MHD (2015-2016) to the DSTU2 version of FHIR. This work is initially started under IHE ITI CP 886, but given the scale of the changes might become a full work-item.
Note that while both FHIR is in Draft Standard for Trial Use (DSTU), and MHD is in Trial Implmentation; the community should expect that experience with these specifications will result in change proposals which will result in changes to the specification. Both HL7 and IHE have governance that covers this phase, governance that allows radical changes to reflect experience.
