【摘要】：目的探讨由多药耐药菌引起的医院感染,为临床制定有效的防治措施提供参考。方法采用回顾性方法对2009-2011年医院感染的监测资料进行统计分析。结果 2009-2011年共有住院患者55 422例,发生医院感染1 755例,感染率为3.17%,2009-2011年感染率分别为2.61%、3.05%、3.93%;其中由多药耐药菌引起的医院感染患者138例,占0.25%,2009-2011年分别为0.22%、0.23%、0.29%;送检细菌培养31 939份,送检率为57.63%,检出病原菌4 469份,检出率13.99%;分离出多药耐药菌1 030株,检出率为3.22%,2009-2011年分别为4.32%、3.81%、1.63%;构成比居前5位的多药耐药菌依次为大肠埃希菌、肺炎克雷伯菌、肺炎链球菌、铜绿假单胞菌、耐甲氧西林表皮葡萄球菌,分别占22.14%、22.04%、17.38%、9.61%、8.64%。结论多药耐药菌检出率逐年下降,而由多药耐药菌引起的医院感染患者不断上升,应引起临床医师和医院主管以及各级卫生行政管理部门的高度重视。
[Abstract]:Objective to explore the nosocomial infection caused by multidrug resistant bacteria (MDR), and to provide reference for clinical prevention and treatment. Methods the data of nosocomial infection surveillance from 2009 to 2011 were analyzed retrospectively. Results in 2009-2011, there were 55,422 inpatients and 1,755 nosocomial infections, and the infection rate was 3.17. In 2009-2011, the infection rate was 2.61and 3.053.93.The number of nosocomial infections caused by multidrug resistance bacteria was 138, which accounted for 0.220.230.2929 in 2009-2011, respectively. The detection rate was 57.63, 4 469 pathogenic bacteria were detected, the detection rate was 13.99, 1 030 multidrug resistant bacteria were isolated, the detectable rate was 3.2220 and the detection rate was 3.323.81and 1.630.The multidrug resistant bacteria that constituted the top 5 were Escherichia coli, Klebsiella pneumoniae and Streptococcus pneumoniae, respectively, in 2009-2011, the results showed that the most important bacteria were Escherichia coli, Klebsiella pneumoniae and Streptococcus pneumoniae. Pseudomonas aeruginosa, methicillin-resistant Staphylococcus epidermidis accounted for 22.14 and 22.04, respectively. Conclusion the detection rate of multidrug resistant bacteria decreased year by year, but the nosocomial infection caused by multidrug resistance bacteria was increasing, which should be paid more attention by clinicians, hospital supervisors and health administration departments at all levels.
