目的了解医院高危科室耐甲氧西林金黄色葡萄球菌(MRSA)医院感染状况,探讨防控措施。方法采用前瞻性调查,对本医院部分科室耐甲氧西林金黄色葡萄球菌感染现状进行了调查。结果连续3年全院共调查到MRSA感染住院患者196例,其中属于医院内获得感染患者108例,另外88例属于社区获得感染;该医院MRSA医院内获得感染病例构成比为55.10%。MRSA感染患者的感染部位以下呼吸道为主,其构成比为69.64%。病例主要分布在神经外科病房,平均每年发生15例;实施干预措施后,2010年度感染病例下降至6例。结论加强医院感染监测,是及早发现MRSA感染的重要手段,采取严格、有效的控制措施,可显著降低MRSA的医院感染率。
Objective To understand the prevalence of nosocomial methicillin-resistant Staphylococcus aureus (MRSA) hospital infection in hospitals and to discuss the prevention and control measures. Methods A prospective investigation was conducted to investigate the status of methicillin-resistant Staphylococcus aureus infection in some departments of the hospital. Results A total of 196 inpatients with MRSA infection were investigated in the hospital for three consecutive years. Among them, 108 were hospital-acquired infections and 88 were community-acquired infections. The prevalence of acquired infections in the hospital was 55.10%. Patients with MRSA infection had the following respiratory tract infection, with a ratio of 69.64%. The cases were mainly distributed in the neurosurgical ward, with an average of 15 cases per year. After the implementation of the intervention measures, the number of cases of infection in 2010 dropped to 6 cases. Conclusion Strengthening the surveillance of nosocomial infections is an important means of early detection of MRSA infection. To adopt strict and effective control measures can significantly reduce the nosocomial infection rate of MRSA.
