Topic: MHD document authors in FHIR
Wolfgang Kronseder (Aug 31 2020 at 07:51):
Hello, has anyone experience how an author of an MHD document is mapped to FHIR resources? The MHD spec lists there some resources like PractitionerResource, Practitioner, Patient, Organization and so on, but there isn't any more detailed information how they are working together when trying to fit an author as specified in the IHE ITI TF-3 specification.
While PractitionerRole seems to be a good fit as describing an author structure (elements for role and speciality, reference to an organization and a practitioner) there are some requirements that can't be covered the standard like:
- An author of a document can also be a patient (or even a software) which means it shouldn't be represented by a practitioner but maybe a patient or a device. Would one create an extension for that?
- An author can belong to more than one organization (authorInstitution). The PractitionerRole resource however limits this per default to an 0..1 relationship.

This is mostly a problem of mapping HL7 v2 datatypes to FHIR. You might find that the #v2 to FHIR topic more helpful.

Realistically there are a few patterns for XDS/XCA use that would simplify this mapping. In that it is not all that common to have a fully specified

most of the time this is just populated with identifiers.
John Moehrke (Aug 31 2020 at 12:25):
most of the time the authorRole , authorSpeciality, and authorTelecommunications are not specified
John Moehrke (Aug 31 2020 at 12:26):
when authorPerson is equal to the Patient, then it is clearly the Patient.
John Moehrke (Aug 31 2020 at 12:26):
when authorInstitution is populated, then authorPerson is likely a Practitioner at that institution

@Oliver Egger @Keith Boone ?
John Moehrke (Aug 31 2020 at 12:29):
least helpful mapping is to just put the identifier from DocuemntEntry into the author.reference.identifier
Keith Boone (Aug 31 2020 at 15:55):
Document author for DocumentReference can be Practitioner, PractitionerRole or Patient (as well as a few other things). In the past, I've used Practitioner and Patient, as those are most aligned with XDS concepts that we started from.
