Terminology
This section lists the coded value sets that are referenced by the FHIR profiles in this implementation guide. These coded values are used to describe and standardize clinical concepts and other data content within health records.
Usage Guidance
Several ValueSets are not available at their canonical URL (e.g., CVC published value sets) or on the terminology servers used in implementation guide publication (i.e., tx.fhir.org). Primarily, this impacts validation against Canada Health Infoway-hosted ValueSets during the development of derived Implementation Guides. This does not affect deployed systems as these instances will be validated against loaded terminology. For several of these ValueSets, "stub" resources have been created to stand-in for the unresolvable ValueSets. These stub ValueSets include pointers to the locations where the full value sets can be downloaded. Current guidance is to manually download the value sets from, for example, the Terminology Gateway or Canadian Vaccine Catalogue. When terminology is not readily available as FHIR® Release 4 ValueSets or CodeSystems, implementers should work with terminology producers to identify options.
Proposed Pan-Canadian Value Sets
These are value sets that are proposed by the Ontario Patient Summary as the national standardized terminologies that implementers are encouraged to align to. SNOMED CT Canadian Edition (SNOMED CT-CA) is the terminology generally recommended for use in Canada, but in some cases the Ontario Patient Summary will also propose the use of other terminologies (e.g., CVC, CCDD, etc.) that have widespread adoption across Canada. While adoption of the national and global value sets is critical for national and global interoperability, recent feedback from participating jurisdictions has outlined the need to prioritize domestic jurisdictional exchange over global exchange in early versions of the specification and as such additional allowed bindings to other value sets are mentioned in the individual profiles, and while implementers are encouraged to align to the proposed pan-Canadian value sets, they should be aware that patient summaries may contain concepts from these other terminologies.
* Use of terminology subsets hosted on Canada Health Infoway Terminology Gateway is recommended in this interoperability specification.
** Use of terminology subsets hosted on the Canadian Vaccine Catalogue is recommended in this interoperability specification. Please note that Canadian Vaccine Catalogue (CVC)-published value set urls are currently not resolvable, but details of the referenced value sets are available in the current version of the CVC accessible here: https://cvc.canimmunize.ca/en/explore#/
