64285例住院患者医院感染病例的监测分析

The monitoring and analysis about hospital infection in 64,285 hospitalized patients cases

目的掌握发生医院感染的薄弱环节,有利于采取相应的遏制措施。方法采取前瞻性调查方式,对本院2009年1月至12月所有住院病例64285例调查统计分析。结果发生医院感染775例,医院感染发生率为1.21%。医院感染率由高到低依次为神经外科(11.5%)、心外科(6.3%)、创伤外科(2.8%)等;医院感染部位以呼吸道感染为首位,构成比为67%。检出病原菌490株,主要是革兰氏阴性杆菌,占69.6%,最常见的病原菌为铜绿假单胞菌(15.3%),其次为大肠埃希菌(15.1%)、肺炎克雷伯(14.3%)、鲍曼不动杆菌(8.6%)、阴沟肠杆菌(6.0%)、MRSA(5.5%)、真菌(8.0%)等。结论针对医院感染流行病学的特点,应加强重点科室目标监测,采取有效的干预措施,降低医院感染率。

Objective Nosocomial infection control weaknesses will help take the appropriate containment measures. Methods A prospective method of investigation,in our hospital from January to December in 2009 for all inpatients survey of 64,285 cases. Results 775 cases of nosocomial infection, hospital infection rate was 1.21% Hospital infection rates in order were neurosurgery （ 11.5 % ）, cardiac surgery （ 6.3 % ）, trauma surgery （ 2.8 % ）, etc; Respiratory tract infection in hospital infection as the first, constitutes more than 67 %. 490 isolated pathogens, mainly gram-negative bacteria,accounting for 69.6 %. The most common pathogens were Pseudomonas aeruginosa （ 15.3 % ）, followed by Escherichia coli （ 15.1% ）, Klebsiella pneumoniae （ 14.3 % ）, Acinetobacter baumannii （8.6 % ）, Enterobacter cloacae（6.0 % ）, MRSA（5.5 % ）, fungi（8.0 % ） ;and so on. Conclusion Epidemiological features of nosocomial infection,strengthening the monitoring of key departments goals, take effective interventions to reduce hospital infection rates.
