住院患者896例医院感染现患率调查与分析

Prevalence survey of nosocomial infection in 896 inpatients

目的调查我院医院感染现患率,为降低医院感染的发生提供依据。方法采取床旁调查和查阅住院病历相结合的方法,对2007-09-27零时至24时的住院患者进行医院感染现患率调查。结果调查住院患者896例,医院感染现患率为4.80%,例次现患率为5.25%;重症监护室(ICU)现患率最高为41.67%;上呼吸道感染占42.55%、下呼吸道感染占25.53%;抗菌药物总使用率为56.36%;术中用药率34.25%。结论为有效地预防和控制医院感染,应提高术中用药率,根据手术情况缩短术后预防用药时间,按药敏用药,避免长期使用抗菌药物造成耐药菌株的出现,提高病原学检查送检率。

Methods A prevalence survey of NI among all the inpatients was made on September 27, 2009 through bed - side interviews and patients＇medical records. Results Of the 896 inpatients investigated, the prevalence rate of NI accounted for 4.80% , and patients＇suffering rate 5.25%. The intensive care unit （ICU） had the highest prevalence rate（41.67% ）. Upper respiratory tract infection accounted for 42.55% , and lower respiratory tract infections 25.53%. The rate of anti - bacterial drug use accounted for 56.36% of the and drug use during operation period 34.25 %.
