运用风险评估法预防控制血流感染

Application of risk assessment method for prevention and control of bloodstream infections

目的运用个性化风险评估表单预防控制血流感染。方法运用风险评估法等手段,建立个性化的血流感染定量风险评估表单,通过随机对照试验(RCT)的方式对118例患者进行试验,其中重症医学科1组(试验组)61例患者,重症医学科2组(对照组)57例患者为对照,以患者出科48h后作为患者观察终点,血流感染率作为衡量指标,比较两组患者预防控制血流感染的临床表现,进一步完善风险评估项目。结果个性风险评估表单在试验组与对照组中预防控制血流感染的作用存在明显差异(χ2=37.21,P<0.05)。结论个性化风险评估表单能够通过预测感染对高风险项目进行干预,进而预防血流感染的发生,但表单的制定是以综合性医院为背景,在专科医院进行推行,结果会有一定的偏差。

OBJECTIVE To prevent and control bloodstream infections by using personalized risk assessment form.METHODS The personalized risk assessment form was developed by using risk assessment method,then the randomized controlled trial was conducted for 118 patients,61patients were assigned as the critical care medicine group 1（the experimental group）,57 patients were set as the critical care medicine group 2（the control group）,the observation endpoint was set at the discharge of the department for 48 hours,the incidence of bloodstream infections was served as the measurement indicator,the clinical performance in prevention and control of the bloodstream infections was observed and compared between the two groups of patients,and the risk assessment program was further improved.RESULTS There was significant difference in the effect of the personalized risk assessment form on prevention and control of bloodstream infection between the experimental group and the control group（χ2=37.21,P〈0.05）.CONCLUSIONThe personalized risk assessment form can intervene in high-risk projects through prediction of infection so as to prevent the bloodstream infection,however,the form is developed based on the blueprint of general hospitals,and there might be certain deviation when it is promoted in specialized hospitals.
