Abstract

Objectives: Radical cystectomy (RC) with urinary diversion has a significant risk of infection. In an effort to decrease the rate of infectious complications, we instituted a broader, culture-based preoperative antimicrobial regimen, including fungal coverage, and studied its effect on infectious complications after RC. Materials and methods: In May 2013, antimicrobial prophylaxis for RC was changed at our institution after review of previous positive cultures. Ampicillin-sulbactam 3 g, gentamicin 4 mg/kg, and fluconazole 400 mg replaced cefoxitin. Patients undergoing RC from May 2011 to May 2014 were included. Before and after implementation of the new regimen, 30-day infectious complications (positive blood culture, urinary tract infection, wound infection, abscess, and pneumonia) and adverse events (Clostridium difficile, readmission, and mortality) were compared. Multivariate logistic regression was used to identify independent risk factors for infection while controlling for covariates. Results: In total, 386 patients were studied (258 before the change and 128 after). The overall infection rate decreased with the new regimen (41% vs. 30%, P = 0.043) with improvements in wound (14% vs. 6%, P = 0.025) and fungal (10% vs. 3%, P = 0.021) infections. Median length of stay decreased from 8 (interquartile range [IQR]: 7-12) to 7 (IQR: 7-10) days (= 0.008). On multivariate analysis, the new regimen decreased the risk of infections (odds ratio [OR] = 0.58, 95% CI [0.35-0.99], P = 0.044) whereas body mass index, operating room time, smoking, and total parenteral nutrition increased the risk (all P< 0.05). Conclusions: Risk factors for infection after RC include body mass index, operating room time, smoking, and total parenteral nutrition use. Changing from cefoxitin to broader, culture-directed antimicrobial prophylaxis, based on institutional data to include antifungal coverage, decreased postoperative infections.
