Purpose
To compare surgical site infections (SSI) rate after radical cystectomy (RC) over time and ascertain whether antibiotic prophylaxis should be enhanced.
Methods
All medical records of RC patients in a single tertiary uro-oncology center between 2007 and 2017 were analyzed. SSI was defined using the criteria of the US Centers for Disease Control and Prevention. All bacterial culture results and antimicrobial resistance rates were recorded. Lastly, multivariable logistic regression analysis was performed to ascertain SSI predictors.
Results
RC was performed in 405 patients, of which 96 (23.7%) developed SSI. No differences were demonstrated in the mean age, gender, NIDDM prevalence, neoadjuvant chemotherapy, positive preoperative urine culture, bowel preparation, and surgery time between both groups. However, statistically significant higher median BMI, age-adjusted Charlson Comorbidity score, usage of ceftriaxone preoperatively, and intensive care unit (ICU) hospitalization were noted in SSI patients. Overall, 62/96 (63.5%) SSI patients had a positive wound culture, with only 16.7% of the pathogens being sensitive to their perioperative antibiotics. Lastly, on multivariable analysis rising BMI, preoperative ceftriaxone and ICU hospitalization were associated with a higher SSI rate.
Conclusions
Preoperative BMI reduction, and maximal preoperative medical optimization in an attempt to lower ICU admittance rates, should be part of the ideal strategy for lowering SSI rates. Additionally, preoperative antibiotics should be enhanced to harbor-wide spectrum coverage, based on local resistance rates.
