老年病房与普通病房老年患者医院感染对比分析

COMPARISON OF NOSOCOMIAL INFECTION BETWEEN GERIATRIC WARD PATIENTS AND THE ELDERLY IN COMMON WARD

目的通过回顾性调查老年病房与普通病房老年患者医院感染不同特点,探讨其防治措施。方法对本院1996年1月～12月老年病房与普通病房60～99岁出院病人进行了回顾性调查与对照分析。结果老年病房医院感染率为8.52%,普通病房医院感染率为2.45%。感染部位以呼吸道、胃肠道、泌尿道为主,但老年病房反复感染机率较普通病房高。病原菌老年病房以肺炎克雷伯氏菌、绿脓假单胞菌为主,其次为真菌。普通病房以肺炎克雷伯氏菌、金黄色葡萄球菌为主。结论两者医院感染发生不同,差异可能与高龄、体质、环境、基础疾病、免疫功能紊乱或低下及药物使用等因素有一定关系。

Objective This paper investigated retrospectively the characterastics of nosocomial infection (NI) in geriatric ward patients and the elderly in common ward. And try to approach the measures of prevention and care. Methods A retrospective survey and comparative analysis between patients of geriatric ward and elderly patients of common ward (age from 60 to 99 years) were carried out. Results Nosocomial infection rates in geriatric ward and common ward were 8.52%and 2.45%respectively. Respiratory tract、gastrointestinal tract and urinary tract were the most frequent sites of NI. However the recurrent infection rate in geriatric ward was higher than that in common ward. The most frequently isolated pathogenic organisms in geriatric ward were Klebsiella, pneumonia, pseudomonas aeruginosa and fungi in such order. Klebsiella and staphylococus aureus were isolated in common ward. Conclusions The difference of NI rate between geriatric ward and common ward may be related to more advanced age, poor constitution &environment, fundamental disorders, lower immune status and drug administration.
