目的了解多重耐药菌(MDROs)感染特点,研究干预措施的效果。方法采取回顾性调查,对某医院住院患者MDROs感染特点进行了监测和防控效果的评价。结果共监测该院2010-2012年住院患者50 377例,发现MDROs感染365例次,例次感染率为7.25‰。在365例次MDROs感染患者中,医院内获得感染142例次,构成比为38.90%;社区获得感染223例次,构成比为61.10%。实施干预措施后,MDROs医院感染率由3.60‰下降至2.23‰。结论该医院MDROs感染主要由社区获得,采取主动监测和实施综合干预措施可以降低其感染率。
Objective To understand the characteristics of multi-drug resistant bacteria (MDROs) infection and to study the effect of interventions. Methods A retrospective survey was conducted to evaluate the surveillance and prevention and control of MDROs inpatients in a hospital. Results A total of 50 377 inpatients from 2010 to 2012 in our hospital were monitored. 365 cases were found to have MDROs infection, and the infection rate was 7.25 ‰. Among the 365 patients with MDROs infection, 142 were hospital-acquired infections with a ratio of 38.90%; 223 were community-acquired infections with a ratio of 61.10%. After the implementation of interventions, the prevalence of MDROs decreased from 3.60 ‰ to 2.23 ‰. Conclusions MDROs in the hospital are mainly acquired by the community. Taking the initiative to monitor and implement comprehensive interventions can reduce their infection rate.
