Persistent post-discharge opioid use and opioid stewardship: A single-centre retrospective cohort study

Persistent post-operative opioid use is a public health concern contributing to population morbidity and mortality. Opioid stewardship is a strategy adopted to rationalise opioid prescribing and limit harmful use. We describe persistent post-discharge opioid use rates and risk factors in a single-centre cohort and describe the opioid stewardship role of our Acute Pain Service (APS). We conducted a retrospective 4-year cohort study of inpatients referred to the APS and discharged with new strong opioids prescribed. We investigated persistent post-discharge opioid use rates, risk factors and patterns of opioid use after community follow-up by APS. We found that 24% of patients discharged with new strong opioids developed persistent opioid use. Risk factors associated with persistent post-discharge opioid use in our cohort included female sex (Odds Ratios 95% confidence interval,
