FHIR: URI for Health Canada Drug Identification Number

Hi Finnie,

We had defined a code system URI for DIN/PIN: hl7.org/fhir/sid/ca-hc-din. Since this is a code system (rather than a value set), this covers the full range of DIN/PIN numbers assigned by Health Canada. You can see this is on the new list of code systems used by FHIR: build.fhir.org/terminologies-systems.html. Every implementation can define a value set that is relevant to its use case as a subset of DIN/PIN numbers, but the code system URI hl7.org/fhir/sid/ca-hc-din will always go to the "system" element of a medication code element in FHIR.

Regards,
Igor

Hi Igor,

Have you also defined a value set URI for DIN that use the full DIN not just a subset? If yes, do you mind sharing it?

Thanks
Finnie

I agree.

I think we should stick to the messages we are implementing in immunization and medication management for the time being. Unless you are volunteering to do them all.

Actually, my proposal was to map all Canadian OIDs to URIs and to use URIs only (not OIDs) in FHIR.
