目的为了解老年感染性疾病住院死亡者医院感染的发生情况、加强医院感染的防治。方法对１９９５年１月～１９９６年１２月因感染性疾病住院死亡的老年病例进行了回顾性调查。结果医院感染发生率为２７．８０％。感染部位以下呼吸道为首位，占医院感染例次数的４１．３８％。原发病以呼吸系统占首位，占３５．０９％，其次为循环系统疾病及肿瘤合并感染，各占３１．５８和１４．０４％。结论医院感染病例的平均住院天数、平均住院费用及抗菌药物的使用种类与非医院感染病例相比均有明显差别
Objective To understand the incidence of nosocomial infections in hospitalized patients with senile infectious diseases and to strengthen the prevention and treatment of nosocomial infections. Methods A retrospective study was conducted on elderly patients hospitalized for infectious diseases from January 1995 to December 1996. Results The incidence of nosocomial infection was 27.80%. The respiratory tract below the infection site was the first, accounting for 41.38% of the number of hospital infection cases. The primary disease with respiratory system accounted for 35.09%, followed by circulatory system diseases and tumor co-infection, each accounting for 31.58 and 14.04%. Conclusion The average days of hospitalization, the average hospitalization cost and the types of antibacterials used in hospital-acquired infections are significantly different from those of non-nosocomial infections
