Opioid prescribing in general practice: an Australian cross-sectional survey

Abstract

Abstract Background Prescribed opioid doses > 100 mg oral morphine equivalent (OME) and/or co-prescribing of sedating psychoactive medications increase the risk of unintentional fatal overdose. We describe general practice encounters where opioids are prescribed and examine high-risk opioid prescribing. Methods The 2006–2016 BEACH study data, a rolling national cross-sectional survey of randomly selected GPs, was analysed. Results Opioid prescribing increased 2006–2007 to 2015–2016, however, this plateaued across the latter half-decade. From 2012–2016 3,897 GPs recorded 389,700 encounters and at least one opioid was prescribed at 5.2%. Opioid encounters more likely involved males, those 45–64 years, concession card holders and the socioeconomically disadvantaged. GPs more likely to prescribe opioids were 55 years or older, male, Australian graduates, and in regional and remote areas. The most common problems managed with opioids involved chronic non-cancer pain. One-in-ten opioid prescribing episodes involved high-risk doses and 11% involved co-prescription of sedating psychoactive medications. Over one-third of GPs provided other (non-pharmacological) interventions at encounters with opioid prescriptions. Conclusions Only 5% of GP encounters involved an opioid prescription. Of concern, were: prescribing for chronic non-cancer pain, potentially high-risk opioid encounters where > 100 OME daily dose was prescribed, and/or there was co-prescription of sedating psychoactive medication. However, approximately one-in-three opioid prescribing encounters involved non-pharmacological interventions.
