Known Issues

Known issues include content or technical issues where the root cause is understood, and the resolution has been discussed and agreed to but have yet to be implemented. This can be due to a number of reasons which include lack of capacity within the current editorial cycle and risk of impact to the stability of SNOMED CT if the fix were to be deployed at that stage in the product lifecycle.

Terminology issues

a) Duplicate concepts

There is the potential that CA Edition concepts duplicate existing concepts in the International Edition. 

The following concept was promoted to SNOMED International but modelled differently from the Canadian concept due to new editorial guidelines.

  • CA Edition concept
    • 60591000087104 |Vaccine product containing only Streptococcus pneumoniae Danish serotype 3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, 15B, 16F, 17F, 19A, 20A, 22F, 23A, 23B, 24F, 31, 33F, and 35B capsular polysaccharide antigens conjugated (medicinal product) |
  • International Edition (core) concept
    • 1360050007 |Vaccine product containing only Streptococcus pneumoniae Danish 3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, de-O-acetylated 15B, 16F, 17F, 19A, 20A, 22F, 23A, 23B, 24F, 31, 33F, 35B capsular polysaccharide antigens conjugated (medicinal product) |

b) Concepts missing definitions and concepts missing refinements

Infoway does not fully model all concepts in the CA Edition because:

  • When submitted to SNOMED International, they will fully model when applicable.
  • International content must be completed and stable before the CA Edition content is modelled fully. 

As a result, there may occasionally be missing defining relationships that could be added to better represent the full and unambiguous meaning of a concept through logical definition.

c) Definition descriptions of the following reference sets will require updates due to changes of scope of the associated valuesets:

  • 22051000087105 |Historical name codes for passive immunizing agents reference set (foundation metadata concept)|
    • Valueset: PassiveHistoricalImmunizingAgentCode
  • 22041000087107 |Administered tradename codes for passive immunizing agents reference set (foundation metadata concept)|Passive administered tradename codes reference set
    • Valueset: PassiveAdministeredImmunizingAgentCode
  • 22071000087104 |Historical name codes for vaccines reference set (foundation metadata concept)|
    • Valueset: VaccineHistoricalNameCode
  • 22061000087108 |Administered tradename codes for vaccines reference set (foundation metadata concept)|
    • Valueset: VaccineAdministeredTradeNameCode

Technical issues

  • MRCM issues

The rows corresponding to the additional attributes (62171000087105 |Has product monograph URL (attribute)| and 62141000087102 |Has last batch on market product expiration date (attribute)|) with concrete values ​​could not be added to the MRCMAttributeDomain and MRCMAttributeRange files.
