Immunization General Notes
The Immunization Subsets immunizationImplementation of the immunization subsets will enable public health and other health care providers to meet the business requirements of recording administration of vaccines (current and past), inventory management and immunization forecasting.
The subsets are supported by a Canadian vaccine model where the concepts and terms are linked together through relationships to allow analytics to be performed. The concepts and terms authored in the SNOMED CT® Canadian extension align with the Public Health Agency of Canada (PHAC) Canadian Immunization Guide (CIG).
In the immunization domain, it is expected that new content will be developed on an ongoing basis and will most probably be exclusive to Canada, although any existing SNOMED CT International content will be leveraged where possible.
The newly developed content will reside in the Canadian Extension/Edition with a status of ‘active’ or ‘current’. The status of ‘current’ means the content remains in the Canadian Extension/Edition because it is not suitable for International inclusion. The status of ‘pending move’ will no longer be used in the future.
Once the Canadian content is promoted to core, the conceptid will be retained by IHTSDO. This will allow the users to use the same conceptid with no disruption or mapping.
The criteria for a concept or a description to be defined with a status of ’current’ is:
- TradeName;
- concept or description with 'unspecified'
- concept or description with 'low dose/standard dose or 'X strength'
The following concepts or descriptions will be candidates for core inclusion. Users can expect these to be promoted to international core:
- Generic substance
- Generic product
Implementing this Release: The subsets with the same colored font complement each other; one subset includes the passive agent and the other includes the vaccine.
The following four subsets should be implemented together:
VaccineAdministeredTradeNameCode |
VaccineHistoricalNameCode |
PassiveAdministeredImmunizingAgentCode |
PassiveHistoricalImmunizingAgentCode |
AntigenCode and ImmunoglobulinCode subsets also complement each other and should be implemented together.
AntigenCode |
ImmunoglobulinCode |
The VaccinePreventableDiseaseCode subset includes diseases that are prevented by administration of vaccines.
VaccinePreventableDiseaseCode |
Capitalization of the FR descriptions (first letter of the description)
- Terms translated as part of the original translation project in 2009 were not capitalized The translated terms were not capitalized when translated in 2009 (as part of the FR translation project)
- French descriptions in the May 2015 extension and the October 2016 release are also not capitalized
- Note that the subsets published by Infoway that contained FR descriptions were manually capitalized to align with the English descriptions.
- For the October 2016 release, the seven (7) Immunization subsets will have French descriptions in lower case unless explicitly stated as these were generated from the authoring tool and not manually augmented.
Canadian Editorial Guidelines
Infoway has developed generic and immunization specific editorial guidelines. These editorial guidelines follow the IHTSDO’s editorial guidance as the baseline, but additional specifications are provided to avoid ambiguity and reflect Canadian specific requirements.
Implementers are encouraged to review the Canadian editorial guidelines before submitting a request for a new concept or a change to an existing concept.
Implementation Considerations
Jurisdictions that have not previously used the immunization subsets may begin to use the new version immediately.
The subsets reference the January 2017 International data files for SNOMED CT and the April 2017 release of the Canadian Extension/Edition.
Jurisdictions that have already implemented the immunization subsets can review the changes from the terminology Gateway change logs. A review of the changes will help to determine how the changes impact the work completed to date.
Some items for consideration:
