Description
One of several codesets in the PEDSnet observation_derivation_recover(ODR) workflow to extract COVID-19 patients from the PEDSnet CDM observation table. This concept set was used to identify pediatric patients under 18 who were prescribed Paxlovid.
The concept set was developed by identifying RxNorm codes at the SCDF/SCDG level and descendants indicating Paxlovid, then string searching for the terms ‘paxlovid’, ‘ritonavir’, and ‘nirmatrelvir’ in ‘concept_name’. Codes were identified in the ‘code_type’ column as ‘Paxlovid’ (indicating nirmatrelvir/ritonavir), ‘nirmatrelvir’ (indicating nirmatrelvir alone) and ‘ritonavir’ (indicating ritonavir alone).
Please note, this concept set should not be used without appropriate accompanying logic to identify Paxlovid; the concept set contains individual ingredients that comprise the combination. Ritonavir and nirmatrelvir exposure must occur together on the same date to indicate a combination drug prescription. The attached file, FIND_PAXLOVID_FUNCITON.R, provides logic showing how the concept set can be used.
