Valuesets - InfoRMS Subset RFC Project 

1. 1. Pan-Canadian SNOMED CT valuesets in scope for this maintenance cycle include: Immunization, Communicable Disease, Primary Health Care and others.
   2. 37 SNOMED CT valuesets are published as extensional reference sets (refsets) in the Canadian Edition (Canada Health Infoway Simple Type Reference Set (foundation metadata concept)).
   3. 29 of 66 valuesets are expanded type valuesets that are intensionally defined (i.e. defined using queries). These can be found as members of the Simple query specification reference set (foundation metadata concept). See below printscreen.

Language Reference set

 In addition to the Canadian English and the Canadian French language refsets, two language refsets were added to support the Public Health Surveillance Community (see Infoscribe page related to Picklists)

• • 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.

• • SNOMED CT to ATC simple map
  • SNOMED CT to CCDD MP simple map
  • SNOMED CT to CCDD TM simple map
  • SNOMED CT to CCDD NTP simple map

Notes for this Release:

1. New vaccine concepts to support the ongoing work for Immunization.
2. Additional concepts for phase 1 of the Canadian Medicines Terminology (CMT) project. Please see the Canadian Medicines Terminology pages for more information.
3. 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.
4. 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).
5. 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 Vitrai.
