Repository for OMOP CDM conventions as defined by THEMIS. These can be reference lists of concepts, pieces of standardized code for data generation or quality certification, and debates.
It looks like there have been a few discussions around what do you you do when you receive multiple modifiers from the raw data. It looks like we got close to a solution with the Vocabulary team discussing pre-coordinated codes however I don't think THEMIS has a formal resolution yet. I think this is worth THEMIS taking a look at.
There was some discussion of overloading the column but then Alexander brought up the Vocab teams plan for precoordinated codes. However I'm not sure if this was completed as it does not sound like a simple task:
PROCEDURE_OCCURRENCE.MODIFIER_SOURCE_VALUE / MODIFIER_CONCEPT_ID - Multiple Modifiers
CDM or THEMIS convention?
THEMIS
Table or Field level?
Field
Is this a general convention?
Field
