Abstract

Background: There is limited information about the incidence and risk factors of surgical site infections (SSIs) after coronary artery bypass (CABG) surgeries in the Omani population. Aim: To estimate the prevalence and describe possible risk factors of SSIs after CABG surgeries in Oman. Method: A retrospective nested case–control design was used to screen 596 patients who underwent CABG surgeries over 2 years (2016–2017) in two tertiary hospitals in Oman. The CDC definition for SSIs was used to identify the infected cases. Results: Prevalence rate of SSIs was 17.4% and 17.5% in 2016 and 2017, respectively. The most isolated microorganism was Gram-positive bacteria (45.2%). Risk factors of SSIs include female gender (OR = 3.2, p < 0.001), diabetes (OR = 5.83, p < 0.001), overweight or obese (OR = 2.14, p < 0.05) and shaving technique [using razor shaving] (OR = 8.4, p < 0.001). Readmission rate for the case group was 44.2%. Conclusion: The infection rate of SSIs after CABG surgeries in developing countries, such as Oman, is considerably high. There is an urgent need to establish SSIs preventive program at the national level. Frequent and systematic assessment of infection control practices before and after CABG surgeries is fundamental and priority strategy to prevent SSIs.
