• • Canadian French Patients Picklists codes reference set
  • Canadian English Patients Picklists codes reference set

Simple map reference sets

4 simple map refsets were created to support the Canadian Medicines Terminology (CMT) project. This information is provided for informational purposes only. These maps are partial and should not be used at this time, as they are subject to change. We are currently evaluating whether these files will be included in the scope of future releases.

New in this release

New concepts to support the phase 1 of the Canadian Medicines Terminology (CMT) project were added. Please see the Canadian Medicines Terminology pages for more information.

Notes for this Release:

1. New vaccine concepts to support the ongoing work for Immunization.
2. Release notes for International releases including the International Edition and the Common French extension are no longer included in the Canadian Edition release package. International release notes can be accessed here and Common French release notes can be accessed here.
3. Inclusion of concepts that originated in other national extensions and were promoted to core because they also meet Canadian requirements and, as such, meet the international use case (lateral promotion).
4. French translation to support Canadian implementations, including: ongoing immunization work; the Canadian Institute for Health Information (CIHI) pan-Canadian Health Data Content Framework (pCHDCF) ; other projects from Ministère de la Santé et des Services sociaux du Québec (MSSS) such as CNESST, CISSSMO and PTI.
