Below are the database queries which are used to create this measure. These are run against a copy of the BSA prescribing data which we store in Google BigQuery. We're working on making our BigQuery tables publicly available at which point it will be possible to run and modify these queries yourself. But even where code and database queries are not directly useable by others we believe it is always preferable to make them public.

---|---|
Why it matters | The MHRA advise that due to the risk of disabling and potentially long-lasting or irreversible side effects, systemic fluoroquinolones must only be used in situations when other antibiotics, that are commonly recommended for the infection, are inappropriate. |
