Pragmatic randomised trial assessing the impact of peer comparison and therapeutic recommendations, including repetition, on antibiotic prescribing patterns of family physicians across British Columbia for uncomplicated lower urinary tract infections
Abstract
Objective: To evaluate the impact of a personalised audit and feedback prescribing report (AF) and brief educational summary (ES) on empiric treatment of uncomplicated lower urinary tract infections (UTIs) by family physicians (FPs).
Design: Cluster randomised control trial.
Setting: The intervention was conducted in British Columbia, Canada between 23 September 2021 and 28 March 2022.
Participants: We randomised 5073 FPs into a standard AF and ES intervention arm (n=1691), an ES-only arm (n=1691) and a control arm (n=1691).
Interventions: The AF contained personalised and peer-comparison data on first-line antibiotic prescriptions for women with uncomplicated lower UTI and key therapeutic recommendations. The ES contained detailed, evidence-based UTI management recommendations, incorporated regional antibiotic resistance data and recommended nitrofurantoin as a first-line treatment.
Main outcome measures: Nitrofurantoin as first-line pharmacological treatment for uncomplicated lower UTI, analysed using an intention-to-treat approach.
Results: We identified 21 307 cases of uncomplicated lower UTI among the three trial arms during the study period. The impact of receiving both the AF and ES increased the relative probability of prescribing nitrofurantoin as first-line treatment for uncomplicated lower UTI by 28% (OR 1.28; 95% CI 1.07 to 1.52), relative to the delay arm. This translates to additional prescribing of nitrofurantoin as first-line treatment, instead of alternates,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 1,691 participants or records.
