【摘要】：目的分析ICU医院感染的危险因素,并制定预防策略,以降低医院感染率。方法对医院ICU 2008年5月-2012年5月收治的1 030例患者临床资料进行回顾性分析,采用χ2检验、单因素及多因素非条件logistic回归分析,模型筛选采用Stepwise法,评价影响感染的危险因素。结果共有330例患者发生医院感染,感染率32.0%;单因素分析显示,侵入性操作、合并基础病、高龄(60岁)、长时间使用免疫抑制剂及抗菌药物、住院时间长等均是医院感染的危险因素;而logistic回归分析显示,机械通气等侵入性操作危险性最大(OR5),其余依次为合并基础疾病(OR=4.781)、高龄(OR=4.374)、长期使用免疫抑制剂(OR=3.647)、长期使用抗菌药物(OR=3.547)、住院时间长(OR=2.247)。结论 ICU医院感染的危险因素较多,临床上应采取针对性的预防对策,从而使感染率得到有效控制。
[Abstract]:Objective to analyze the risk factors of ICU nosocomial infection and to make preventive strategies to reduce nosocomial infection rate.Methods the clinical data of 1 030 patients with ICU from May 2008 to May 2012 were retrospectively analyzed. The risk factors of infection were evaluated by 蠂 2 test, univariate and multivariate logistic regression analysis and Stepwise method.Results A total of 330 patients developed nosocomial infection and the infection rate was 32.0.The univariate analysis showed that invasive operation, complicated with basic diseases, aged 60 years old, and prolonged use of immunosuppressive agents and antibiotics,The length of stay in hospital was the risk factor of nosocomial infection, and logistic regression analysis showed that,The risk of invasive operation, such as mechanical ventilation, was the greatest, and the others were OR4.781, 4.374, 3.647, 3.547, and 2.247, respectively.Conclusion there are many risk factors for ICU nosocomial infection.
