摘要

ObjectiveThe effect of total exemption from medical service co-payments on drug prescribing practices has not been extensively evaluated. We conducted a retrospective cross-sectional study to evaluate the effect of total exemption from medical service co-payments on potentially inappropriate medication (PIM) and benzodiazepine use in elderly ambulatory patients. We defined PIM based on the Beers Criteria.
