1195例老年住院病人中发生医院感染共99例(8.28％),感染部位以下呼吸道占首位(52％),其次为泌尿道(16.6％)。共分离菌株235株,以革兰氏阴性杆菌为主,其中克雷白菌属、绿脓杆菌和肠杆菌属共占培养菌株的73.5％,老年病人医院感染与增龄导致的免疫功能减退;同时存在多种慢性病等因素有关,感染大多由自身正常菌群引起,且对抗生素多重耐药。

Among 1195 aged in patients, 99 cases hadnosocomial infection (8.28%). The principal sites ofinfection were lower respiratory tract, accounting for52%, followed by urinary tract 16.6%, and others. 235rods were isolated, the G(-) bacilli were the mostcommon species, Klebsiella, Pseudomonas andEnterobacter account for 73.5% of all rods. They areparticularly susceptible to infection because of defi-ciencies in their immunologic function, the occurrenceof more than one underlying diseases. Nosocomial in-fection in elder are often attributable to members ofthe endogenous human microflora that happen to beparticularly resistant to antibiotics.
