Surgical site infections (SSIs) are a significant burden to patients and health care systems. This retrospective study evaluates the observed rates of SSI after our institution implemented chlorhexidine gluconate-impregnated (CHG) cloth as a preoperative antiseptic preparation in elective vascular surgery.Between March 2011 and January 2012, we reviewed 250 patients who underwent elective vascular surgery who used the CHG cloth preoperatively. Their rate of SSIs was compared with 252 control patients who received the CHG shower preoperatively during the preintervention period. Urgent and emergent cases were excluded. The primary outcome measured was SSI within 30 days of index operation.There was no baseline difference in mean age, gender distribution, smoking status, diabetes, chronic obstructive pulmonary disease, and the number of patients with body mass index >40 between the cohorts. There was no difference in the overall rate (5.6% vs. 5.6%, P = 1.00) and type of SSIs between the 2 groups, but the control group trended toward deeper infections (4 deep incisional and 2 organ space vs. none and 1, respectively). The control group also had more dirty or infected wound categories (10 vs. 21.4%, P < 0.01) and more perioperative antibiotic errors and hypothermia (P < 0.02).There was no observed difference in SSI rates before and after implementation of the CHG as the preoperative method of skin decontamination in our retrospective case-control cohorts.
