An Assessment Scale for Patients with Postoperative Superficial Incisional Surgical Site Infection: a Cross-Sectional Study.

Abstract

Superficial incisional surgical site infection (SSI) is a common postoperative complication in surgical patients. The aim of this study was to assess the predictive power of an assessment scale for identifying patients at risk of superficial incisional SSI. A cross-sectional survey was conducted at the Department of Surgery at the Medical Research Institute Hospital, Alexandria University. A sample of 150 adult patients aged from 18 to 65years, who undergoing general surgeries that had clean sutured surgical wounds, was randomly selected. Forty-six patients (30.7%) had SSI. The total score can significantly discriminate between positive and negative superficial incisional SSI patients with diagnostic accuracy of AUC (SE)=0.66 (0.048). Each score more than the cutoff point (11.5) will increase the risk of surgical site infection development by 2.5 times (OR (95% CI)=2.5 (1.26-3.1)). The developed assessment scale can discriminate between patients who are at risk of superficial incisional SSI and those who are not. It can be used as a preliminary screening tool for subsequent investigation for the presence of infection.
