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.
| Description | Total quantity where a prescription is for four pens per prescription as a proportion of all semaglutide prescribing |
|---|---|
| Why it matters | Semaglutide is a new (glucagon-like peptide-1) GLP-1 agonist, used to treat diabetes. It comes as a pre-filled pen and is used weekly. Each of these pens contains four doses and a single pen will last for one month However, there have been some reports that prescribers are requesting four pens per month in error. This is unlikely to be required and likely to be caused by the dose and quantity being confused on a picking list. |
