Build Drug-Medical Condition Relationship

I understand. Except - why do you need that? You might want it:

  • To support patient care, so the doc looking at a patient with MS will see Mayzent. DON’T! The OMOP CDM is not designed for patient care. We are studying populations in an observational setting (patients all in the past).
  • To support cohort construction. This would be useful, but as I explained in the other post it doesn’t work, because the way patient are diagnosed is at a different level of granularity than treatment assignment is done. As in the example of the itching cream. The indication will be “itch”. That is not a diagnosis. There could be a gazillion reason why there is an itch.

Also, generally we are trying to create associations between drugs and diseases, i.e. it is the output of our work. You want that as the input.
