2009年医院感染病原菌分布特点及对照研究

Distribution of pathogens causing nosocomial infection in 2009:a comparative study

目的探讨邯郸市中心医院2009年住院患者医院感染病原菌分布特点,并与唐山市工人医院相应数据进行比较。方法对2009年分离的3889株病原菌分布特点进行分析。结果邯郸市中心医院感染病原菌以革兰阴性杆菌为主,占66.57%,其次为革兰阳性球菌,占23.38%,真菌占10.05%;与唐山市工人医院相应数据比较,革兰阴性杆菌和革兰阳性球菌构成比低于邯郸市中心医院,真菌构成比显著高于邯郸市中心医院。结论唐山市工人医院在控制革兰阴性杆菌和革兰阳性球菌医院感染方面好于邯郸市医院,在控制真菌医院感染方面邯郸市中心医院好于唐山市工人医院。

OBJECTIVE To investigate distribution of pathogenic bacteria causing nosocomial infection in inpatients in 2009 and compare corresponding data of Tangshan workers hospital with our hospital. METHODS The distributional characteristics of 3,889 strains of isolated pathogens were analyzed during the period from Jan 2009 to Dec 2009. RESULTS The isolation rate of Gram-negative bacteria was 66.57% in 3,889 strains of pathogens, while that of Gram-positive bacteria was 23.38%, The fungi had the lowest isolated rate （10.05%） in 3,889 strains of pathogens. The distributional character of pathogenic bacteria of our hospital was compared with Tangshan workers hospital, the constituent ratios of Gram-negative and Gram-positive bacteria in Tangshan workers hospital were lower than that in Handan central hospital, while the constituent ratios of fungi in Handan central hospital were significantly higher than that in our hospital. CONCLUSION The control of Gram-negative bacilli infection and Gram-positive cocci infection in Tangshan workers hospital is better than that in our hospital, but the control of fugal infections in our hospital is better than that in Tangshan workers hospital.
