Age over 60, diabetes, smoking, obesity, and wound drains are significant risk factors for surgical site infections in Iranian teaching hospitals.
Arabshahi et al. (2006) conducted a cohort in Surgical site infection (n=918). Diabetes mellitus vs. Patients without diabetes mellitus was evaluated on Surgical site infection (SSI) (OR 4.9, p=<0.0001). Diabetes mellitus (OR 4.9), obesity (OR 4.1), age >60 years (OR 3.9), smoking (OR 3.1), and wound drains (OR 2.2) were significant risk factors for surgical site infection, which occurred in 8.4% of patients.
