  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.

    dm+d version of non-high dose opioid codelist.

    Taken from long-acting opioid denominator 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. "
