Is this trial a fit for you?

Likely a good fit

Ideal candidates include neonates, infants, and children hospitalized in Pediatric and Neonatal ICUs who are receiving intravenous antibiotics for less than 24 hours for bacterial infections.

Probably not a fit

Patients who are immunocompromised, have cystic fibrosis, or are newborns less than 72 hours old will not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of a procalcitonin (PCT)-guided algorithm for discontinuing antibiotic therapy in critically ill children with suspected or proven bacterial infections. Conducted in seven Pediatric and Neonatal Intensive Care Units in France, the study randomly assigns 296 eligible patients to either the PCT-guided group or the standard-of-care group. The goal is to determine if the PCT-guided approach can safely reduce the duration of antibiotic treatment without increasing the risk of infection recurrence. Participants will be monitored for 28 days or until the end of their hospitalization.

Why it matters

Potential benefit: If successful, this approach could lead to shorter antibiotic courses, reducing the risk of antibiotic resistance and associated adverse effects in critically ill children.

How similar studies have gone: While similar studies in adults have shown efficacy, data in critically ill children is limited, making this approach novel in this specific population.
