Background: Evaluate the incidence, potential risk factors, management and outcome of postoperative infections.

Methods: This is a prospective study between August 2017 and October 2018 taking place in a Middle Eastern tertiary care center. The sample was collected using infectious disease consultations, and cases specified by doctors and residents of surgery. The definition of the surgical site infection used was the one defined by the Center for Disease Control and Prevention (CDC). The following variables were collected: age, arterial hypertension, diabetes, hyperlipidemia, tobacco smoking, immunosuppression, type of surgery, preoperative antibiotic therapy, the site of infection, the causative organism, the resistance profile of the infective organism, the treatment and the prognosis of the infection.

Results: Escherichia coli (36%) was the most frequent causative bacteria in postoperative infections, followed by Staphylococcus aureus (10%). 65% of the Enterobacteriaceae secrete an extended spectrum beta lactamase (ESBL), and 12.5% of the Staphylococcus aureus were methicillin resistant. The Altemeier score seems to affect the incidence of infections. The antibiotic prophylaxis was well targeted in 90.9%. A targeted postoperative antibacterial treatment was initiated in 86% versus 14% of inappropriate antibiotics. The duration of treatment was appropriate in 72.8% of cases. These postoperative infections had a favorable evolution in 58%, and a recurrence rate of 23%. No potential risk factor was found significant in this study.

Conclusion: Strategies to prevent and decrease such complications must be implemented in every hospital. More studies are needed to determine the frequency and epidemiology of the postoperative infections. Better-targeted management is warranted.
