内科病房老年病人医院感染调查

Investigation of nosocomial infection of medical elderly inpatients in our hospital

目的 了解我院老年病人医院感染情况 ,为预防老年人医院感染提供客观依据。方法 对 1996年 1月～ 1998年 12月我院内科 6 0 1例住院老年病人采取前瞻性与回顾性调查相结合的方法进行目标性监测。结果 本组老年病人医院感染率为 8.32 % ,明显高于我院这 3年的平均医院感染率 (1.48% )。感染部位以下呼吸道发生最多 ,占医院感染的 5 2 %。以内分泌、循环、消化、泌尿、呼吸系统疾病等医院感染发生率较高。检出的医院感染病原菌以条件致病菌——真菌为主 ,占85 %。结论 老年人免疫功能低下 。

Objective To find out nosocomial infection of elderly patients in our nosocomial and to provide theoretical evidence for preventing nosocomial infection of elderly patients. Methods 601 elderly patients of internal medicine in our hospital were investigated with prospective and retrospective methods from January 1996 to December 1998. Results Nosocomial infectious rate in this age was 8.32%, and it was higher than mean nosocomial infectious rate in our nosocomial during the last three years(1.48%). Infectious sites was mostly the lower respiratory tract, and it's infectious rate was 52%. Basic diseases such as endocrine system, circulatory system, digestive system, genitourinary system, respiratory system diseases were higher in nosocomial infection. Opportunitive pathogens were the main cause of the nosocomial infectious pathogens, and fungi took 85% of the opportunitive pathogens. Conclusions Nosocomial infectious factors are mainly that immune function is lower in the aged and antibiotic is used generally.
