Reducing inappropriate outpatient antibiotic prescribing: normative comparison using unblinded provider reports

ImportanceAntibiotic resistance is a global health issue. Up to 50% of antibiotics are inappropriately prescribed, the majority of which are for acute respiratory tract infections (ARTI).ObjectiveTo evaluate the impact of unblinded normative comparison on rates of inappropriate antibiotic prescribing for ARTI.DesignNon-randomised, controlled interventional trial over 1 year followed by an open intervention in the second year.SettingPrimary care providers in a large regional healthcare system.ParticipantsThe test group consisted of 30 primary care providers in one geographical region; controls consisted of 162 primary care providers located in four other geographical regions.InterventionThe intervention consisted of provider and patient education and provider feedback via biweekly, unblinded normative comparison highlighting inappropriate antibiotic prescribing for ARTI. The intervention was applied to both groups during the second year.Main outcomes and measuresRate of inappropriate antibiotic prescription for ARTI.ResultsBaseline inappropriate antibiotic prescribing for ARTI was 60%. After 1 year, the test group rate of inappropriate antibiotic prescribing decreased 40%, from 51.9% to 31.0% (p
