Impact of a region wide antimicrobial stewardship guideline on urinary tract infection prescription patterns

Background Fluoroquinolones are frequently prescribed for non complicated urinary tract infection treatments and have a negative ecological impact. We aimed to substitute them by antibiotics with narrower activity spectrum in order to preserve fluoroquinolone activity in complicated hospital infections. Objective To assess the impact of a multi-modal approach that combines the dispatching of antibiotic prescription guidelines and voluntary attendance at educational sessions on general practitioners’ (GP) antibiotic prescription habits. Setting This study was led in Franche-Comté, a French eastern region, where GPs were given a guideline recommending a restricted use of fluoroquinolones for urinary tract infections. Method Segmented regression analysis of interrupted time series was used to assess changes in antibiotic prescription. Main outcome measure: The antibiotic prescription data of nitrofurantoin, fosfomycin-trometamol and fluoroquinolones for women aged 15–65 years were obtained from the regional agency of health insurance. Results Twenty months after intervention, the number of nitrofurantoin and fosfomycintrometamol prescriptions increased by 36.8% (95% CI: 30.6–42.2) and 28.5% (95% CI: 22.9–35.4), respectively, while that of norfloxacin decreased by 9.1% (95% CI: −15.3 to −3.5). Conclusion This study suggests that the dispatch of the guideline on urinary tract infection had a moderate impact on antibiotic prescriptions.
