I am new to OMOP and currently are doing concept mapping. I mapped a list of local drug names to RXCUI. But I found that 1/3 of the RXCUI is either “obsolete” or “is not current” when I did quality control by searching in RxNAV. For example, 1000717 (seb-prev 10 % topical gel) and 83018 (dynabac) are obsolete, 644844 (influenza virus vaccine trivalent 2006-2007) and 476598 (monoamylamine) are not current.
But the status of these RXCUIs in the recently released RXNCONSO (07062020) are NOT suppressed. Then I searched in the retired, archived, and changed RXCUI tables but none of them could be found in those tables except 1000717 is archived.
I have two questions:
Should I NOT used the RXCUI that is “obsolete” or “is not current”?
If I should not use RXCUI that is “obsolete” or “is not current”, could anybody tell me how to identify all the “obsolete” or “is not current” RXCUI in RXNCONSO table instead of searching one by one on RxNAV?
Any help is Wellcome. Thank you very much in advance.
