BACKGROUND An intervention Prescription Opioid Practice Improvement (POPI), addressing opioid prescribing on discharge following orthopaedic surgery, demonstrated improved practice. Here we report the sustainability of improved practice at 12 months, and the impact of a booster education intervention, POPI SOS (Safe Opioid Supply). METHODS Audits were performed using methodology described in previously published studies. RESULTS High proportion of patients were discharged on opioids, 89.9% 12 months post-POPI (n = 149) and 82.2% post-POPI SOS (n = 169). Twelve months post-POPI there was a significant reduction in combination immediate (IR) and slow release (SR) opioids, 45.7% at the end of POPI program to 34.3% at 12 months (χ2 (1, N = 364) = 4.47, ρ = 0.034); a significant decrease in opioid-weaning plans, 87.4% at the end of POPI program to 35.8% at 12 months (χ2 (1, N = 365) = 104.19, ρ = <0.001); and a significant increase in provision of full quantities of SR-opioids, 6.1% after the POPI program to 15.7% (χ2 (1, N = 364) = 8.95, ρ = 0.003). The POPI SOS booster program significantly improved measures including reduction in combination IR and SR, 34.3-22.3% (χ2 (1, N = 273) = 4.87, ρ = 0.028) and an increase in opioid plans in discharge summaries, from 35.8% to 77.7% (χ2 (1, N = 273) = 48.87, ρ < 0.001). CONCLUSION Better practice in relation to opioid prescribing is achievable but, for sustained improvement, opioid stewardship activities are needed to reduce the potential harms associated with prescription opioids.
