老年病人医院感染危险因素分析

Analysis on Risk Factors of Hospital Infection among Elderly Patients

目的探讨老年病人医院感染特点及危险因素。方法对年龄≥60岁以上发生医院感染的159例病人的医院感染部位、年龄分布、基础疾病住院时间、检出菌种等进行统计分析。结果本组老年人医院感染率为13.8%,感染部位以呼吸道及泌尿道为主,感染发生率与年龄、住院时间成正相关、基础疾病是影响医院感染的重要因素。检出的菌种以白色假丝酵母菌、铜绿假单胞菌、表皮葡萄球菌占前3位。结论老年人医院感染率高,其危险因素主要有病人的基础疾病、营养不良、高龄、长时间住院等。

Objective To discuss the risk factors of hospital infection among elderly patients. Methods A total of 159 patients with hospital infection over 60 years old were statistically analyzed on the aspects of infected site, age distribution, primary disease, hospitalization duration, detected bacterial species, and so on. Results The hospital infection rate was 13.8% among the elderly patients. The infected sites were mainly respiratory and urinary tracts. The infection rate was positively correlative with age and hospitalization duration. The primary disease played an important part that had influence on the infection. The first three detected bacterial species were candidaalbicans, pseudomonas aeruginosa and staphylococcus epidermidis. Conclusion Hospital infection rate is comparatively high among elderly patients, and its main risk factors include such aspects as primary disease, senility and long - term hospitalization.
