Examining opioid prescribing trends for non-cancer pain using an estimated oral morphine equivalence measure: a retrospective cohort study between 2005 and 2015.

Over the study period, OMEQe burden nearly doubled, with disproportionate OMEQe prescribed in the most deprived communities. Using OMEQe provides an alternative measure of prescribing and allows easier comparison of the contribution different drugs make to the overall opioid burden.
