Background/Purpose
While the use of oral antibiotic (OA) for bowel preparation is gaining popularity, it is unknown whether it increases the risk of Clostridium difficile infection (CDI). This study aimed to evaluate the impact of OA on the development of CDI after colectomy.
Methods
Patients who underwent colectomy from the ACS-NSQIP data (2015 and 2016) were included. Patients who received OA as bowel preparation were compared to those who did not with respect to demographics, comorbidities, primary diagnosis, procedure type and approach, and 30-day postoperative complications. Multivariable analysis was performed to characterize the association between OA and CD infection after colectomy. A sub-group analysis was also conducted for patients who did not develop any postoperative infectious complication.
Results
Of 36,374 included patients, 18,177 (50%) received OA and 527 (1.4%) developed CDI for the whole cohort. OA group had more younger, functionally independent and obese patients with lower American Society of Anesthesiologists and wound class. Smoking, diabetes, hypertension, dyspnea or ventilator-dependence, congestive heart failure, disseminated cancer, bleeding disorder, and perioperative transfusion were significantly higher for non-OA group. Mechanical bowel preparation, minimally invasive surgery, conversion to open and operative duration ≥ 180 min were more prevalent in the OA group. The OA group had significantly reduced occurrence of CDI; superficial, deep, and organ space infections; wound disruption; anastomotic leak; reoperation; and infections including sepsis, septic shock, pneumonia, and urinary tract infection. On multivariable analysis, OA reduced the odds for CDI after colectomy (OR = 0.6, 95% CI = [0.5–0.8]). For patients who did not develop infectious postoperative complications, OA was associated with lower risk of CDI (OR = 0.7, CI = [0.5–0.9]). While complications, reoperation, and readmission rates were the same, postoperative ileus and hospital stay were significantly lower for those who developed CDI after receiving OA when compared to non-OA.
Conclusion
The use of OA as bowel preparation may reduce, rather than increase, the risk of 30-day CDI after colectomy. This effect may partly be due to the other recovery advantages associated with oral antibiotics. These data further support current data recommending the use of oral antibiotics for bowel preparation before colectomy.
