Description

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

User requirements I need a codelist 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

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
