目的探讨预警控制系统对控制重症监护病房（ICU）医院感染的可行性,为预测和控制医院感染提供理论指导。方法选取2012年1月-2013年12月入住医院ICU的398例患者作为观察组,采用前瞻预警模型方法;选取2010年1月-2011年12月入住ICU的354例患者作为对照组,比较两组患者医院感染感染率,采用SPSS17.0软件进行统计分析。结果 398例发生医院感染51例,感染率为12.81%;与实施前比较,差异有统计学意义（P〈0.05）;预警控制模型诊断58例患者出现医院感染,感染率为14.57%,经Kappa分析,预警控制模型诊断与临床实际诊断存在一致性（P〈0.05）;预警控制模型诊断的灵敏度为76.47%、特异性为94.52%。结论预警控制模型有着较高的可信度和可行性,可以对ICU患者是否发生医院感染进行提前预测,并对可能出现医院感染的患者进行针对性预防和控制,从而使ICU医院感染由被动预防转变为针对性预防,有助于降低ICU医院感染率。

英文摘要：

OBJECTIVE To investigate feasibility of the early warning and control model to control hospital infections in intensive care unit（ICU）,so as to provide theoretical guidance for the prediction and control of hospital infections.METHODS Totally 398 cases in the ICU from Jan.2012 to Dec.2013 were selected as the observation group which adopted the method of the early warning and control model.And 354 cases in the ICU during Jan.2010 to Dec.2011 were selected as the control group.The infection rates were compared between the two groups of patients.The software SPSS17.0was used for statistical analysis.RESULTS Totally 51 out of 398 cases had hospital infections with the incidence of 12.81%;compared with the prior to the implementation,the difference was significant（P〈0.05）.The model diagnosed that 58 cases had hospital infection with the incidence rate of14.57%.The Kappa analysis showed the model diagnosis was consistent with the actual clinical diagnosis（P〈0.05）.The sensitivity of the early warning and control model was 76.47%,and the specificity was 94.52%.CONCLUSIONThe early warning and control model has high credibility and feasibility,which can predict in advance whether patients have infections in ICU,and perform targeted prevention and control for suspected patients with hospital infections,so that the control of hospital infections in ICU can changed from passive prevention to targeted prevention,which is beneficial for reducing the hospital infection rate in ICU.
