OP85 Persistence Leads To Ongoing Decreases In Primary Care Antibiotic Use

Abstract

IntroductionAustralia has had high rates of antibiotic use in primary care. Consumer and health professional knowledge and practices in the community vary. In 2012, NPS MedicineWise implemented a five-year national educational program for consumers, general practitioners (GPs) and pharmacies to reduce antibiotic use in Australia.MethodsFor consumers, a social marketing approach was used focusing on the winter months. Strategies leveraged collectivism, nudge theory, celebrity endorsement and co-creation and used multiple communication channels. For health professionals, interventions were most intense in 2012 with additional activities implemented each year including face-to-face educational visiting, audits, comparative prescribing feedback, case studies and point-of-care materials. Surveys were conducted periodically to evaluate changes in knowledge and awareness. Pharmaceutical Benefits Scheme (PBS) claims data were analyzed. Organization for Economic Co-operation and Development data was used to compare Australian antibiotic per capita consumption to other countries. Time series analyses were used to estimate the cumulative program effect comparing observed and expected monthly dispensing volumes of antibiotics commonly prescribed for upper respiratory tract infections (URTIs), had interventions not occurred.ResultsBetween 2012 and 2017, GP antibiotic PBS prescriptions reduced by 18.4 percent. Antibiotic defined daily doses per 1000 inhabitants reduced from 23.7 in 2012 to 18.4 in 2016, similar to Norway (18.6 in 2016) and the UK (18.7). Time series modelling estimated 24.8 percent fewer GP antibiotic URTI prescriptions by 2017 versus no program. Consumer survey results indicated increased awareness of antibiotic resistance (50 percent in 2011, 74 percent in 2017) and the minority expect/request antibiotics for URTIs (22 percent in 2017).ConclusionsA five-year national educational program with multiple and repeated interventions for health professionals and consumers has resulted in ongoing reductions in antibiotic use in primary care.
