Abstract

Background: Surgical site infections (SSIs) cause considerable morbidity and deaths among patients undergoing vascular surgery. Pre-operative screening and subsequent treatment of nasal Staphylococcus aureus carriers with mupirocin and chlorhexidine reduces the risk of SSIs in cardiothoracic and orthopedic surgery. The aim of this study was to investigate the effect of this screen-and-treat strategy on the development of SSI in patients undergoing aortoiliac surgery.<br />Methods: A prospective study was performed that enrolled an intervention cohort comprising all patients undergoing aortoiliac surgery from February 2013 to December 2016. Before surgery, patients were screened for S. aureus nasal carriage and, if positive, were treated with mupirocin nasal ointment and chlorhexidine body washes. The presence of SSI was recorded on the basis of the criteria of the U.S. Centers for Disease Control and Prevention. A historic control group was used, consisting of aortoiliac surgery patients in 2010 who tested positive for S. aureus but received no treatment.<br />Results: A total of 374 patients in the study cohort were screened of whom 75 (20.1%) tested positive for S. aureus. Of these patients, 68 were given eradication therapy. In the 2010 cohort, 22 patients (15.7%) were positive. The incidence of S. aureus infection was 0 of 75 in the treatment group versus 3 of 22 (13.6%) in the control group (pā€‰=ā€‰0.021). Both the 30-day mortality rate (1.3% vs. 13.6%; pā€‰=ā€‰0.035) and the rate of re-interventions (12.0% vs. 31.8%) were significantly lower in the treated group.<br />Conclusion: We conclude that S. aureus nasal screening and eradication with mupirocin and chlorhexidine reduces S. aureus SSI and its complications after aortoiliac surgery.
