Topic: Questionnaire Responses & References to Versions
Ed Costello (Jul 16 2016 at 03:58):
Hi, I'm trying to map some existing concepts of a forms / clinical documentation system to FHIR questionnaires. One concept I'm considering how to map across is questionnaires that capture observations that have a life beyond the questionnaire.
It seems like the correct mapping of this that the question is answered by an observation reference to an observation. But I'd like to be some record of the observation the user thought they were using when they were completing the questionnaire, just incase that observation is subsequently modified.
This would seem to call for a reference to a particular version of a resource rather than just to the resource. Is this a concept that's come up? Or am I way off base?

Resource references can indeed be to a version specific instance of a resource.
If you do link to the version specific form, then would want ways to verify that the item is infact an older version.

Thanks, I couldn't find a reference to that in the docs. Is it just a link that matches the vread operation? i.e. [base]/[type]/[id]/_history/[vid]

Yes. All references are allowed to be version-specific.
