目的了解某医院院内感染状况及其影响因素,以便加强监控,减少和杜绝医院感染的发生。方法对2009年全年761例院内感染患者临床资料进行回顾性分析。结果感染患者的平均住院时间为30.1天,大于2009年平均住院天数12.3天;院内总感染率3.60%,易感原发病、某些侵袭性操作等为院内感染的主要因素。结论院内感染延长了住院的时间,增加了住院费用;加强病室通风、消毒、隔离机制,以减少医院感染的发生几率。
Objective To understand the nosocomial infection status and its influencing factors in a hospital in order to strengthen the surveillance and reduce and prevent the occurrence of nosocomial infections. Methods The clinical data of 761 nosocomial infections in 2009 were analyzed retrospectively. Results The average length of stay of hospitalized patients was 30.1 days, which was larger than the average length of hospital stay of 12.3 days in 2009. The total hospital infection rate was 3.60%. The primary disease and some invasive procedures were the main factors of nosocomial infection. Conclusion Nosocomial infection prolongs hospitalization time and increases hospitalization expenses. It also strengthens the ventilation, disinfection and isolation mechanisms of the wards in order to reduce the incidence of nosocomial infections.
