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.

阿曼冠状动脉搭桥术后手术部位感染的发生率和危险因素。

背景：关于阿曼人群冠状动脉搭桥术后手术部位感染（SSIs）的发生率和危险因素的信息有限。目的：评估阿曼冠状动脉旁路移植术后SSIs的患病率并描述可能的风险因素。方法：采用回顾性嵌套病例对照设计，对阿曼两家三级医院在2年（2016-2017年）内接受冠状动脉旁路植入术的596名患者进行筛查。疾病控制与预防中心对SSIs的定义用于识别感染病例。结果：2016年和2017年SSIs的患病率分别为17.4%和17.5%。分离最多的微生物是革兰氏阳性菌（45.2%）。SSIs的危险因素包括女性（OR=3.2，p<0.001）、糖尿病（OR=5.83，p<0.001），超重或肥胖（or=2.14，p<0.05）和剃须技术（or=8.4，p<0.001）。病例组的复发率为44.2%。结论：在阿曼等发展中国家，CABG手术后SSIs的感染率相当高。迫切需要在国家一级建立SSIs预防计划。CABG手术前后对感染控制实践进行频繁和系统的评估是预防SSI的基本和优先策略。
