RT Journal Article SR Electronic T1 Provider effects in antibiotic prescribing JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0523-12900R1 DO 10.3368/jhr.0523-12900R1 A1 Huang, Shan A1 Ullrich, Hannes YR 2024 UL http://jhr.uwpress.org/content/early/2024/05/01/jhr.0523-12900R1.abstract AB In the fight against antibiotic resistance, reducing antibiotic consumption while preserving healthcare quality presents a critical health policy challenge. 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.
