Hello all, I am newer to the community and am in need of some guidance!
I am trying to build a list of RxNorm drugs with hierarchical details. I read this thread: https://forums.ohdsi.org/t/concept-hierarchies AND ATC release - Vocabulary Users - OHDSI Forums as it’s similar to what I am trying to accomplish but in table form.
Currently I have RxNorm and Extension drugs as descendants with ATCs mapping to them as ancestors, so that I have all existing ATC information (and codes) per RxNorm drug. My hope is to have some time of hierarchical information per concept, but I am not as of now.
My goal is to have something like this for each RxNorm concept:
codeine phosphate 2 MG/ML : NERVOUS SYSTEM | ANALGESICS | OPIOIDS | Natural opium alkaloids | codeine, combinations excl. psycholeptics; systemic
Is this a solid way to make a hierarchy in the drug domain? Is it even possible with ATC to RxNorm relationships? Does anyone have tips, other articles to read, or advice?
Thank you in advance!
