【摘要】 目的　了解老年住院患者院内感染情况和病原菌的耐药变迁。方法　对我院 1999年 1月～ 2 0 0 1年 1月两年间住院老年患者 30 0 5例进行院内感染调查。结果　老年院内感染发生率为 6 5 9% ,明显高于普通院内感染率 3 48% (P <0 0 5 )。感染的病原菌以革兰阴性杆菌为主 ( 6 6 13 % ) ,其次是真菌 ( 2 1 12 % )和革兰氏阳性球菌 ( 12 6 6 % ) ,以多重耐药的ESBLs和MRSS多见 ,白色念珠菌的感染也不容忽视。结论　老年患者易发生院内感染 ,对老年患者应采取积极预防 ,防治结合的原则。更多还原

【Abstract】 Objective In order to know the condition of nosocomial infecfion on geriatric in-patients and the variation of pathogens with their drug resistances.Methods The geriatric in-patiens were investigated. Results The positive rate of geriatric nosocomial infection was 6.59%,the over all nosocomial infection was 3.08%.The main pathogens of geriatric nosocomial infection were Gram-negative bacteria(66.13%),as well as fungi(21.12%)and Gram-positive bacteria (12.66%).The most pathogens were multidrug-resistant bacteria,such as extended-spectrum β-lactamases(ESBLs)and methicillin resistant coagulase-negative staphylococcus(MRSCN).The candida albicans infection should be noticed too.Conclusions The geriatric in-patients are susceptible population to nosocomial infection,and the most isolated pathogens are multidrug resistant.It is very important that the geriatric nosocomial infection must be initially prevented,also combined with effecfive therapy.更多还原
