Surgical Site Infection in the General Surgery Department at the Fousseyni Daou Hospital in Kayes

Abstract

Objectives: To determine frequency, analyze risk factors, identify responsible germs and antibiotic susceptibility, and assess the cost of infection. Patients and Method: We conducted a prospective study (August 1, 2022 to February 2023) for a period of 6 months. During our series, we received 250 patients who had been operated on and hospitalized in the general surgery department. The diagnosis of surgical site infection was based on criteria set forth by the Atlanta CDC. Data collection was carried out by interviewing, consulting records and anaesthesia sheets. Surgical wound monitoring was done up to the 30th postoperative day. A sample was taken for each infection. The word processor and tables were made on Microsoft Word 2019. Data were captured and analyzed on SPSS software (version 25). Results: We collected a total of 250 patients in our study. 31 developed an infection of the surgical site, a frequency of 12.4%. There were 31 patients, including 23 men and 8 women, with a mean age of 34 years, with a standard deviation of 20.75. The most common type of infection was superficial incision infection with 70.9% followed by deep incision infection with 29.1%. Risk factors for Surgical Site Infection Were: haemoglobin level; the nature of the surgery; ALTEMEIR contamination class 3 and 4; NNISS index 1 and 2; the type of intervention with probability tests P<0.05. The analysis of the 31 samples resulted in 31 positive cultures, i.e. a bacteriological yield of 100%. Echerichia coli was the most isolated germ with 25.8%, followed by Enterobacter cloacae 19.3% and Enterococcus 19.3%. The Treatment was: Carrying out local care based on antiseptics (dakin; Betadine; hydrogen peroxide) and general (adapt to susceptibility testing). The consequence of surgical site infection was the prolongation of the hospital stay by an average of 19 days for infected patients; with an estimated additional cost of 294712 and 0% mortality.
