Background: Over the past 20 years prescription of opioid medicines has markedly increased in the UK, despite a lack of supporting evidence for use in commonly occurring, painful conditions. Prescribing is often monitored by counting numbers of prescriptions dispensed, but this may not provide an accurate picture of clinical practice. Aim: To use an estimated oral morphine equivalent (OMEQe) dose to describe trends in opioid prescribing in non-cancer pain, and explore if opioid burden differed by deprivation status. Design & setting: A retrospective cohort study using cross-sectional and longitudinal trend analyses of opioid prescribing data from Welsh Primary Care General Practices (PCGP) took place. Data were used from the Secure Anonymised Information Linkage (SAIL) databank. Method: An OMEQemeasure was developed and used to describe trends in opioid burden over the study period. OMEQeburden was stratified by eight drug groups, which was based on usage and deprivation. Results: An estimated 643 436 843 milligrams (mg) OMEQewas issued during the study. Annual number of prescriptions increased 44% between 2005 and 2015, while total daily OMEQeper 1000 population increased by 95%. The most deprived areas of Wales had 100 711 696 mg more OMEQeprescribed than the least deprived over the study period.Conclusion: Over the study period, OMEQeburden nearly doubled, with disproportionate OMEQeprescribed in the most deprived communities. Using OMEQeprovides an alternative measure of prescribing and allows easier comparison of the contribution different drugs make to the overall opioid burden.
