OpenCodelists

Welcome to OpenCodelists, created by OpenSAFELY for creating and sharing codelists.

Anybody can also use this tool to create and share codelists. To get started, take a look at the documentation or watch the videos.

High dose long acting opioids (OpenPrescribing) - Pseudo BNF BNF

Taken from high dose long-acting opioid codelist in OpenPrescribing, with a calculated Oral Morphine Equivalence of ≥120mg a day of a long acting regular opioid.

From OpenPrescribing: "The calculations are based on likely doses of long acting, regular opioids, for example morphine sulphate tablets or fentanyl patches. For example, we have assumed that MST 60mg tablets are “high dose”, as they are usually taken as one tablet twice daily (120mg daily dose), whereas MST 30mg are not, as the daily dose is 60mg. We have not included preparations used for breakthrough pain, e.g. Oramorph, or opioid injections which tend to be used more commonly in palliative care. "
