  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    A codelist to identify all prescribing of Paxlovid (Nirmatrelvir with Ritonavir).

    User requirements Codelist needed to return all recorded prescriptions of Paxlovid in primary care records. This will be used to plot the recorded prescribing in primary care of all COVID-19 therapeutics.

    Sensitivity versus specificity Volumes expected to be low, and drugs specific, so sensitivity to be prioritised
