Impact of community pharmacist antibiotic prescribing for minor ailments: an interrupted time series analysis
In 2023 and 2024, pharmacists submitted over 1.47 million minor ailment claims, with UTIs making up 34.2% and LD prophylaxis making up 2.6% of total claims. UTI claims were primarily for women aged 25-64, and LD prophylaxis peaked in spring and fall. Pharmacist prescribing of eligible urinary drugs in females increased by 33.3 per 1000 person-years (95% CI 30.8 to 36.6) while physician prescribing decreased by 23.3 (95% CI -32.2 to -15.3), leading to a modest net increase of 10.1 (95% CI 0.0 to 18.7). Pharmacist prescribing of doxycycline was offset by decreased physician prescribing, resulting in no change (0.0, 95% CI -1.0 to 0.9). Pharmacist prescribing for other antibiotics was low over the study timeframe, while physician prescribing increased, which was driven by increased prescribing of penicillins and macrolides.
