BackgroundMost antibiotics prescribed to children are provided in the outpatient and emergency department (ED) settings, yet these prescribers are seldom engaged by antibiotic stewardship programs. We reviewed ED antibiotic prescriptions for three common infections to describe current prescribing practices.MethodsPrescription data between 2018 and 2021 were extracted from the electronic records of children discharged from the Children's Hospital of Eastern Ontario ED with urinary tract infection (UTI), community acquired pneumonia (CAP), and acute otitis media ≥2 years of age (AOM). Antibiotic choice, duration, as well as the provider's time in practice and training background were collected. Antibiotic durations were compared with Canadian guideline recommendations to assess concordance. Provider-level prescribing practices were analyzed using k-means cluster analysis.Results10,609 prescriptions were included: 2868 for UTI, 2958 for CAP, and 4783 for AOM. Guideline-concordant durations prescribed was generally high (UTI 84.9%, CAP 94.0%, AOM 52.8%), a large proportion of antibiotic-days prescribed were in excess of the minimally recommended duration for each infection (UTI 16.8%, 19.3%, AOM 25.5%). Cluster analysis yielded two clusters of prescribers, with those in one cluster more commonly prescribing durations at the lower end of recommended interval, and the others more commonly prescribing longer durations for all three infections reviewed. No statistically significant differences were found between clusters by career stage or training background.ConclusionsWhile guideline-concordant antibiotic prescribing was generally high, auditing antibiotic prescriptions identified shifting prescribing towards the minimally recommended duration as a potential opportunity to reduce antibiotic use among children for these infections.Copyright © 2023.
