1992年元月-1997年12月我院综合病房(老年病房)共收治≥60岁患者2492例,其中有381例发生医院感染。医院感染率15.29%,高于全院医院感染率(8.7%)。1-4月医院感染率及呼吸道感染率最高,与本地区山区气候有关,其余部位感染无明显季节分布,与社区感染不同。感染率和性别无明显关系,随年龄增长而增高。本组病人抗生素使用率(85.3%),高于全院抗生素使用率(67%)。医院感染的病人中培养出致病菌株125株,以革兰氏阴性杆菌为主81株(64.8%),培养出真菌17株(13.6%)。提出一些降低老年病人医院感染的必要措施。
From January 1992 to December 1997, a total of 2492 patients aged 60 years or older were admitted to our comprehensive ward (senile ward), of which 381 were hospitalized. The hospital infection rate was 15.29%, which was higher than the hospital infection rate (8.7%). From January to April, the highest rate of nosocomial infections and respiratory tract infections was related to the mountain climate in this area. The rest of the infections did not have obvious seasonal distribution and was different from community infections. There was no significant relationship between the infection rate and gender, and it increased with age. The use of antibiotics in this group of patients (85.3%) was higher than the use of antibiotics in the hospital (67%). Among the nosocomial infection patients, 125 strains of pathogenic strains were cultured, 81 strains (64.8%) were Gram-negative bacilli, and 17 strains (13.6%) were cultured. Put forward some necessary measures to reduce nosocomial infection in elderly patients.
