Abstract

Background: Antimicrobial resistance is a worldwide phenomenon that leads to a significant number of unnecessary deaths and costly hospital admissions. More than 90% of antibiotic use happens in the community and of this, family physicians account for two-thirds of these prescriptions. Our study aims to determine whether family medicine residents are optimally trained in antibiotic prescribing for common infectious conditions seen in a primary care setting.

Methods: This study is a secondary analysis of a prior study of antimicrobial stewardship in two urban primary care clinics in central Toronto, Ontario. A total of 1099 adult patient visits were included that involved family medicine resident trainees, seen between 2015 and 2016. The main outcome measures were resident antibiotic prescription rates for each condition and expert-recommended prescribing practices, the rate prescriptions were issued as delayed prescriptions, and the use of first-line recommended narrow-spectrum antibiotics.

Results: Compared to expert-recommended prescribing rates, family medicine residents overprescribed for uncomplicated upper respiratory tract infections (URI) (5.0% [95% CI 2.2% to 9.7%] versus 0% expert recommended) and sinusitis (44.2% [95% CI 32.8% to 55.9%] versus 11%-18% expert range), and under prescribed for pneumonia (53.5% [95% CI 37.7% to 68.8%] versus 100% expert range]). Prescribing rates were within expert recommended ranges for pharyngitis (28.6% [95% CI 16.6% to 43.3%]),…
