  • 演講摘要 : Overprescribing antibiotics cause antimicrobial resistance that undermines drug effectiveness and jeopardizes health care procedures that deemed safe otherwise. As antimicrobial resistance has become a pressing health care crisis around the world, this paper investigates potential reasons behind unnecessary antibiotics prescriptions for viral infections using large-scale, administrative healthcare data from Taiwan. Empirical results support the supply side explanation with physician agency, where pharmaceutical markup, estimated to be 27% of the regulated price, is found to increase with unnecessary antibiotic prescriptions. But prescriptions that were not dispensed by the prescribing doctors included fewer antibiotics than the other prescriptions. Physician owners are also found to be more likely to prescribe unnecessary antibiotics than the other practitioners. Empirical results do not support the demand side explanation as antibiotics prescriptions were found to reduce the chance of patients' returning visits.
