Shortening antibiotic courses for common throat and chest infections in primary care with doctor–pharmacist teamwork and viral‑circulation updates
Official title: Impact of a Multimodal Intervention on Antibiotic Prescribing for Respiratory Infections in Primary Care: A Cluster-Randomized Trial
Run by University Hospital, Caen · NCT07359287 · Data updated 2026-11-12
This project will test whether giving primary care doctors and pharmacists extra information about circulating viruses plus a shared protocol helps shorten antibiotic courses for patients with common respiratory infections.

Is this trial a fit for you?
✓Likely a good fit
Patients seen in participating primary care practices for upper or lower respiratory infections (for example angina, acute bronchitis, bronchiolitis, AECOPD, laryngitis, otitis, sinusitis, or community‑acquired pneumonia) are ideal candidates.
✕Probably not a fit
Patients under legal protection are excluded, and individuals with complicated infections requiring individualized longer antibiotic courses are less likely to benefit from standardized shorter durations.

What this trial studies
This is a cluster-randomized trial conducted in six primary care practices (24 physicians) affiliated with CHU Caen Normandie, with three practices randomized to a bimodal intervention and three to usual care. The intervention combines regular communication about the circulation of respiratory viruses and a multidisciplinary GP–pharmacist protocol to verify that prescribed antibiotic durations follow guidelines. The primary aim is to see if this package reduces the duration of antibiotic treatments for upper and lower respiratory tract infections. Eligible encounters include a wide range of acute respiratory diagnoses, and patients under legal protection are excluded.
Why it matters
Potential benefit: If successful, the approach could reduce unnecessary antibiotic exposure and its side effects while helping slow antimicrobial resistance.
How similar studies have gone: Previous antimicrobial stewardship and GP–pharmacist collaboration programs have shown reductions in antibiotic use, so this combines established strategies into a novel two‑part intervention.
