Non standard drug_concept_id mapped to standard concept with different concept_class

As per OMOP CDM v5.3 , we need to consider below given concept_class for drug exposure but some non standard drug_concept_id is mapped to standard drug_concept_id with cconcept_class like Marketed Product.

Do we need to consider such standard concept_id which belongs to different concept_class

This is totally fine.
Where did you take the snapshot from? We need to add “Marketed Product” to this note.

@chawdary:

You seem to confuse Concept Class and Drug Class. One is an attribute of a Concept, as explained in the text. The other one is it’s own Concept, denoting a Drug Classification from another vocabulary, like ATC. The text really is not clear about that. Did you get that from the Book of OHDSI?

we are referring OMOP CDM v5.3

The current version of the paragraph in the OMOP CDM 5.4 specification document is:

Currently, the following concept_class_id involving standard concepts in the concept table are:
query: select distinct concept_class_id from concept where standard_concept like ‘S’ and domain_id like ‘Drug’;

result: [‘Clinical Pack Box’, ‘Branded Drug Form’, ‘Clinical Pack’, ‘Ingredient’, ‘Quant Clinical Drug’, ‘Clinical Drug’, ‘Branded Drug’, ‘Quant Branded Drug’, ‘CVX’, ‘Vaccine Group’, ‘Branded Drug Box’, ‘Marketed Product’, ‘CPT4 Modifier’, ‘Clinical Drug Comp’, ‘Quant Branded Box’, ‘Clinical Drug Form’, ‘Branded Pack Box’, ‘Quant Clinical Box’, ‘Branded Pack’, ‘Branded Drug Comp’, ‘Clinical Drug Box’]

I am not completely sure about the current order of precedence to follow if I have to map new drugs or update my mappings. If possible, could you please update this paragraph in the specification with the updated order or let me know to whom I need to contact to do so?

Thank you very much!!! :wink:

Your query is missing the clause "and vocabulary_id in (‘RxNorm’, ‘RxNorm Extension’), because we have a few odd standard drug concepts. Not happy about them, but not urgent to squish them out.

But you are right. It’s not the full list. The sentence should be:

These are indicated in the CONCEPT_CLASS_ID field of the CONCEPT table and need be recorded in the following order of precedence: Marketed Product, Quant Branded Box, Quant Clinical Box, Branded Pack Box, Clinical Pack Box, Branded Pack, Clinical Pack, Branded Drug Box, Clinical Drug Box, Quant Branded Drug, Quant Clinical Drug, Branded Drug, Clinical Drug, Branded Drug Form, Branded Drug Comp, Clinical Drug Form, Clinical Drug Comp and only if no other information is available, Ingredient.
