Analysis of current situation and influencing factors of surgical site infec-tion in surgical patients
Objective To investigate the status and influencing factors of surgical site infection(SSI)in surgical patients.Methods Clinical data of 5 420 patients undergoing surgical operations in Maanshan People's Hospital of Anhui Province from January 2020 to December 2021 were collected,and SSI and pathogenic bacteria were recorded.According to SSI status,the patients were divided into infected group(46 cases)and non-infected group(5 374 cases).The clinical data of the two groups were compared,and the influencing factors of SSI were determined by multivariate logistic regression analysis.Results The incidence of SSI was 0.85％(46/5 420).Among the 48 isolates,31 isolates(64.58％)were Gram negative bacterium and 17 isolates(35.42％)were Gram positive bacterium.The proportion of patients with age＞65 years old,diabetes mellitus,general anesthesia,type of incision Ⅲ,emergency surgery,American College of Anesthesiologists gradeⅢ,and preoperative use of antibiotics in the infection group were higher than those in the non-infection group,operation time and hospital stay in the infection group were longer than those in the non-infection group,the differences were statistically significant(P＜0.05).Analysis of influencing factors showed that age(OR=2.125,95％CI:1.104-4.090),combined diabetes(OR=2.585,95％CI:1.327-5.036),and timing of surgery(OR=2.209,95％CI:1.306-3.736),operation time(OR=2.704,95％CI:1.325-5.518),hospital stay(OR=2.767,95％CI:1.348-5.680),incision type(OR=2.159,95％CI:1.128-4.325),and preoperative use of antibiotics(OR=0.784,95％CI:0.673-0.995)were the influencing factors for SSI in surgical patients(P＜0.05).Conclusion Age,diabetes mellitus,timing of surgery,duration of surgery,length of hospital stay,type of incision,and use of antibiotics are the influencing factors for SSI in surgical patients,and early intervention for these factors is conducive to reducing SSI.
