[摘要] 目的 了解医院感染基本情况及相关因素，以加强医院感染的预防和控制。 方法 采取横断面调查法，进行床边逐个调查。 结果 3次总医院感染现患率为5.82%，总例次现患率为5.94%。各年感染现患率、例次现患率比较差异均有统计学意义(P均< 0.05)。下呼吸道是医院感染最主要的部位。重症医学科医院感染现患率均为最高，10个科室3年调查现患率差异有统计学意义(P < 0.05或P < 0.01)。3年感染标本送检率及检出病原菌菌株阳性率均呈上升趋势(P < 0.01)。年龄、侵入性操作、重症监护、抗生素联用及住院时间与医院感染发生关系密切(P < 0.05)。 结论 本医院感染现患率符合国内对三级甲等医院的要求，近3年现患率呈下降趋势，下呼吸道仍是主要的感染部位，加强危险因素控制，以利于防止医院感染发生。
