What this trial studies
In adults 18 to 65 with acute cystitis and no complications, the study compares following the standard French delegation protocol to a version that also uses a shared decision-making tool. The goal is to see if informing patients about benefits and risks leads some to avoid antibiotics, potentially reducing unnecessary antibiotic use. Participants are recruited at participating community pharmacies, receive information, and are followed by phone after 14 days to assess antibiotic use and outcomes. The study uses a non-randomized, protocol-based approach to evaluate decision-making processes in real-world settings. Outcomes include antibiotic consumption, patient-reported scales, satisfaction, and healthcare visits.
Why it matters
Potential benefit: If successful, the approach could reduce unnecessary antibiotic use for uncomplicated acute cystitis and support patient-centered care.
How similar studies have gone: Previous work suggests informed, shared decision-making can influence antibiotic prescribing in some settings, but this specific approach in French pharmacy delegation protocols is novel.
