The clinical and economic impact of surgical site infections after distal pancreatectomy

The present study aimed to evaluate surgical site infections' clinical and economic impact after distal pancreatectomy.The study was a prospective, monocentric, observational study, including all adult patients who underwent distal pancreatectomy. According to the American Centers for Disease Control and Prevention definition, the surgical site infection assessment was prospectively performed by trained personnel. The Accordion Severity Grading System was used to evaluate the clinical burden of surgical site infection. The hospitalization's total costs were calculated using the hospital expenditure report, excluding the intraoperative costs.During the study period, 414 distal pancreatectomies were performed. The overall incidence of surgical site infection was 26% (106 patients). Surgical site infections were associated with a higher body mass index (P = .022, odds ratio 1.2), positive preoperative rectal swab for multidrug resistant bacteria (P = .010, odds ratio 4.2), and increased operative time (P = .037, odds ratio 1.1). Using the Accordion Severity Grading System, surgical site infections contributed significantly to the total clinical burden (25.5%) and prolonged hospitalization (P < .001). Furthermore, surgical site infection doubled the costs (12.915 vs 6.888 euros, P < .001).Surgical site infection has a high clinical burden, negatively impacting the postoperative course. The costs and length of stay proportionally increased with the surgical site infection severity, doubling the hospitalization expenses.
