医院肠球菌感染危险因素的调查分析与防治对策

Investigation on Risk Factors of Enterococcal Infection in Hospital and it' s Preventive Measures

目的 了解医院肠球菌感染的现状,分析危险因素,制定预防措施,控制肠球菌感染。方法对临床44例肠球菌感染病例进行回顾性调查,并对肠球菌感染的分布部位、危险因素及耐药情况进行分析。结果 肠球菌感染率以内科最高,占40.9％,部位以下呼吸道感染为主。危险因素以侵入性装置比例最高,为77.3％。这些菌株对临床常用抗菌药耐药性强,患者病死率高;但尚未发现耐万古霉素肠球菌。结论 肠球菌感染呈上升趋势,对多种抗菌药呈高度耐药,易引起医院感染的流行。加强消毒隔离工作,合理应用抗生紊,减少侵入性装置的应用,缩短住院日,可预防和控制医院肠球菌感染。

Objective Understanding the current situation of enterococcal infection in the hospital, analysis of the risk factors and making preventive measures to control the infection. Method By retrospective analysis of 44 cases of enterococcal infection the area of distribution,risk factors and drug-resistance coere analyzed. Results Incidence of enterecoccal infection was increased in our hospital,It was highest in the department of internal medicine (40.9%) .The susceptible site is lower respiratory tract.The highest risk(77.3%) was invasive installation. The enterococcal strain had strong resistance to antibiotics, leading to high mortality. Till now, we haven' t found resistance to vancomycin. Conclusion The incidence of enterococcal infection is increasing , with high drug-resistance to antibiotics thus the infection prevails in the hospital. The possible preventive and control measures include strict disinfection and sterilization, reasona the use of antibiotics, less use of invasive installation, and reduction of hospital stay.
