Testing targeted antibiotics to prevent infections after bladder surgery

REINFORCE - Reducing Infection-related Readmissions Following Cystectomy. a Multicentre Randomised Clinical Trial Testing Superiority of Individualised Targeted Antibiotic Prophylaxis Over Empiric Prophylaxis At Ureteral Stent Removal to Reduce Infection-related Readmissions Following Cystectomy.

PHASE4 · Rigshospitalet, Denmark · NCT06709196

What this trial studies

This trial aims to determine if using targeted antibiotics based on urine bacteria can lower the risk of infections following cystectomy compared to standard antibiotic prophylaxis. Participants will be randomly assigned to receive either a standardized antibiotic regimen or a targeted antibiotic treatment based on their urine culture results. The study seeks to address the high rate of infection-related readmissions after bladder surgery by evaluating the effectiveness of a more personalized antibiotic approach. The trial is multicenter and open-label, involving several hospitals in Denmark.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for cystectomy with an ileal conduit urinary diversion.

Not a fit: Patients with a history of severe allergic reactions to antibiotics or those on long-term prophylactic antibiotic treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative infections and hospital readmissions for patients undergoing cystectomy.

How similar studies have performed: While there is limited high-evidence research on antibiotic prophylaxis after cystectomy, the study's targeted approach is innovative and may provide new insights into infection prevention.
