目的了解上海市某区综合性医院院内耐甲氧西林金黄色葡萄球菌(MRSA)感染现状及分布特点,以便加强防控措施。方法通过回顾性调查方式,对上海市某区4所综合性医院住院病人中MRSA感染现状进行调查与分析。结果所调查的4所医院在2008年度共发现金黄色葡萄球菌感染患者248例,其中MRSA感染203例,占金黄色葡葡球菌感染的81.85%。全院住院病人中MRSA感染发病率为2.68‰,病人主要分布于ICU,占32.5%。医院MRSA感染患者预后不良,病死率高达27.59%。结论该区4所综合性医院住院病人MRSA感染率为2.68‰,MRSA在检出的金黄色葡葡球菌中占81.85%,需要加强ICU MRSA感染的防控措施。
Objective To understand the status and distribution of methicillin-resistant Staphylococcus aureus (MRSA) infection in general hospitals in a district of Shanghai in order to strengthen prevention and control measures. Methods By means of retrospective survey, the prevalence of MRSA inpatients in 4 general hospitals in a district of Shanghai was investigated and analyzed. Results In the four hospitals investigated in 2008, a total of 248 cases of Staphylococcus aureus infection were found, of which 203 cases were MRSA infection, accounting for 81.85% of those infected with Staphylococcus aureus. The hospital inpatient MRSA infection incidence was 2.68 ‰, the patient is mainly distributed in the ICU, accounting for 32.5%. Hospital patients with poor prognosis of MRSA infection, mortality rate as high as 27.59%. Conclusions MRSA prevalence of inpatients in 4 general hospitals in this area is 2.68 ‰, and MRSA is 81.85% in the detected Staphylococcus aureus. Therefore, prevention and control measures of MRSA in ICU need to be strengthened.
