Evaluating antibiotic treatment duration for community-acquired pneumonia

Adherence to Clinical Guidelines Regarding the Duration of Antibiotic Treatment in Patients Hospitalized for Community-acquired Pneumonia With Clinical sTability. ADAPT Study

Not applicable Interventional Instituto de Investigacion Sanitaria La Fe · NCT05762328

This study is testing whether reminding doctors to follow guidelines on how long to give antibiotics can help patients with mild pneumonia get better while using fewer unnecessary antibiotics.

What this trial studies

This clinical trial aims to assess adherence to clinical guidelines regarding the duration of antibiotic treatment in patients hospitalized for non-severe community-acquired pneumonia (CAP) who have reached clinical stability. The study will be conducted over two years, with the first year focusing on observational data collection to evaluate current practices. In the second year, interventions will be implemented to remind clinicians to adhere to recommended treatment durations, thereby aiming to reduce unnecessary antibiotic use. The trial will involve multiple centers to gather a diverse patient population.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years hospitalized for community-acquired pneumonia with clinical stability after at least 3 days of antibiotic treatment.

Not a fit: Patients with severe pneumonia requiring intensive care, or those with specific exclusions such as active tuberculosis or immunosuppression, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more appropriate antibiotic use, reducing side effects and antibiotic resistance in patients with community-acquired pneumonia.

How similar studies have performed: Previous studies have shown that adherence to clinical guidelines can improve patient outcomes, suggesting potential success for this approach.
