Summary
There are several concepts in SNOMED of the type Allergy to animal x dander (finding) but none of just Allergy to animal x (finding). Animal dander is not an allergen but rather a structure on which allergenic proteins may adhere. Allergy to animal x dander concepts are not clinically useful as avoidance would be focused on the animal itself rather than a part of the animal and most would not recognize a specific source from which the actual allergen is derived. In addition, the same allergenic protein may be found in several different sources. The group would like the CMAG to consider a request to inactivate Allergy to animal x dander (finding) concepts and replace with new Animal protein x (substance) and Allergy to animal x (finding concepts) with the following model:
FSN=Allergy to animal x protein (finding)
PT=Allergy to animal x
=== 420134006 |Propensity to adverse reaction (finding)|: { 719722006 |Has realization (attribute)| = 472964009 |Allergic process (qualifier value)|, 246075003 |Causative agent (attribute)| = |Animal protein x (substance)| }

| USA | 27OCT2020 | The proposal seems generally reasonable. A few value sets in NLM's Value Set Authority Center refer to Allergy to animal x dander (finding) concepts and will be directly affected if we do inactivation/creation rather than modification (which I can understand for editorial reasons). I am wondering whether procedure concepts also referring to "animal x dander" remain appropriate or would need to be refactored similarly to the corresponding Allergy concepts – they could be similarly genericized (e.g., Cat allergen specific immunoglobulin E antibody measurement). Just a thought. |
| NL | 27OCT2020 | Agreed! |
