It looks like there may be two standard concept_ids for the concept ‘exerbation of asthma’.
I do see that the concept name in the omop concept table for (the active) SNOMED concept is ‘acute asthma’, however this is just the SNOMED preferred term for ‘exacerbation of asthma’.in the US edition.
It seems that Exacerbation of asthma was created to replace invalidated Exacerbation concept in SNOMED (not sure though, tagging @zhuk).
Now, SNOMED hierarchy itself is not that intuitive - they have Acute asthma (which has exacerbation as a synonym) and Acute exacerbation of asthma as a descendant, which to me sounds like two equivalent concepts. Altogether, it seems that we have three standard terms for the same concept Aside from creating confusion, does it have an impact on your activities?
Its descendants are more specific, but the concept itself is non-specific. Or am I missing something?
@aostropolets - I see what you’re saying.
SNOMED is using the expressions ‘Exacerbation of asthma’ and ‘Acute exacerbation of asthma’ in the FSN to describe the same idea (an asthma attack). it’s inconsistent and non-intuitive as you say.
I wonder if I’m missing something now?
Acute asthma (aka exacerbation of asthma) is a parent concept of child concepts that are all more specific subtypes of acute asthma (e.g., acute exacerbation of chronic asthmatic bronchitis). That looks accurate to me.
“Acute asthma” (Concept ID 257581) has the synonyms “Exacerbation of asthma”,
“Asthma attack” and “Exacerbation of asthma (disorder)”.
It’s child “Acute exacerbation of asthma” (Concept ID 45771045) has the synonyms “Acute exacerbation of asthma (disorder)” and “Asthma attack”.
What exactly is the additional attribute that the child adds to what’s inherited from the parent? It’s not the acuteness (both of them have it), and it’s not the attack (both have it), and it’s not the exacerbation (both have it). Now what? Time to complain to SNOMED.
(Except the new version has it fixed. Can you see, @aostropolets?)
In new version that is not yet in the OHDSI Vocabs? Haven’t checked it. Otherwise yes, I also saw the child and the parent as being totally same terms.
