We investigate the role of practice styles in patients' antibiotic intake using exogenous variation in patient-physician assignment. Practice style heterogeneity explains 49\% of the differences in overall antibiotic use and 83\% of the differences in second-line antibiotic use between primary care providers. We find no evidence that high prescribing is linked to better treatment quality or fewer adverse health outcomes. Policies improving physician decision-making, particularly among high-prescribers, may be effective in reducing antibiotic consumption while sustaining healthcare quality.}, language = {en} }
