Effect of Antibiotic-Prescribing Feedback to High-Volume Primary Care Physicians on Number of Antibiotic Prescriptions

Does providing a single, mailed, peer-comparison letter on antibiotic use to high-prescribing primary care physicians targeting either initiation or duration of antibiotic treatment modify prescribing behavior?

In this randomized clinical trial of 3500 primary care physicians in Ontario, Canada, receipt of a letter targeting appropriate antibiotic durations resulted in a statistically significant 4.8% relative reduction in total antibiotic use.

A single, peer-comparison, antibiotic-feedback letter to high-prescribing physicians can be effective and cost saving, especially if it includes targeted messaging on appropriate durations of antibiotic prescriptions.
