【摘要】 目的研究老年患者医院感染的特征,为制定有针对性的防治措施提供可靠依据。方法回顾性分析3870例医院感染患者,≥60岁的为老年组共1839例、<60岁的为非老年组共2031例,对2组医院感染发病性别、发病部位以及感染病原菌等进行对比分析,分析老年患者医院感染的特征。结果老年组医院感染发病率是非老年组的1.51倍,男性高于女性;感染部位分布构成比前3位依次为呼吸道占66.10%、胃肠道占14.72%、泌尿道占9.60%;老年组医院感染病死率13.81%,是非老年组的8.52倍;致病菌以革兰阴性菌为主占60.19%;分离病原菌构成比前3位是真菌占20.81%、铜绿假单胞菌占15.80%、大肠埃希菌占13.34%。结论老年患者医院感染发病率、病死率高,感染部位以呼吸系统为主,真菌是主要致病菌,可为临床诊疗提供依据。更多还原

【Abstract】 OBJECTIVE To know about the epidemiological characteristics about the nosocomial infection,so as to provide the exact treatment for the nosocomial infection. METHODS A total of 3 870 inpatients with nosocomial infection in the last three years were collected,and then divided into two group was greater than or equal to 60 years old the other was less than 60 years old,so as to conclude the Epidemiological characteristics about the nosocomial infection of the aged patients. RESULTS The aged patients′ infection incidence rate is 1.51 times higher than the non-aged patient,and the male are higher than the female;the major infection parts were respiratory tract(66.10%),gastrointestional tract(14.72%) and urinary(9.60%);the case fatality rate of the age patients was 13.81%,8.52 times than the non-aged patients;60.19% pathogenic bacteria were Gram-negative bacterium,and the first three pathogenic bacteria were epiphyte(20.81%),Pseudomonas aeruginosa(15.80%) and Escherichia coli(13.34%). CONCLUSION The incidence rate and case fatality rate are higher in the aged in-patient;the major infection part is the respiratory tract;the epiphyte is the most important pathogenic bacteria.更多还原
