目的了解某医院住院患者及老年住院患者医院感染的现状,以提高对老年人医院感染的重视。方法利用信息化监控系统对某院2014年-2015年94 673例全院总住院患者医院感染情况进行回顾性分析,其中老年住院患者25 924例。结果两年老年住院患者医院感染率为2.57%;老年住院患者医院感染与性别、年龄、住院时间、基础疾病具有相关性;老年住院患者医院感染部位前三位依次为下呼吸道、上呼吸道、菌血症,与全院住院患者医院感染部位略有不同;老年住院患者医院感染高发科室前三位是外科ICU、综合ICU、干三科;2014年老年住院患者器械相关(呼吸机、中心静脉插管、尿管)感染率分别为20.96‰、5.60‰、5.33‰;2015年分别为27.63‰、2.16‰、6.01‰。结论老年住院患者是医院感染高危人群,加强对其监控,采取有效预防控制措施,控制老年住院患者医院感染能有效降低医院感染。
Objective To understand the current status of nosocomial infections in hospitalized patients and elderly hospitalized patients in a hospital so as to enhance the importance of nosocomial infection in the elderly. Methods A retrospective analysis was performed on 94 673 hospitalized patients with nosocomial infections in a hospital from 2014 to 2015 using an information-based monitoring system, of which 25 924 were elderly inpatients. Results The prevalence rate of nosocomial infection was 2.57% in two-year-old hospitalized elderly patients. There was a correlation between nosocomial infection and gender, age, hospitalization time and underlying diseases in elderly hospitalized patients. The top three hospitalized nosocomial patients were lower respiratory tract, upper respiratory tract, Serum, and hospital-wide hospital inpatient infection site slightly different; Elderly hospitalized patients with high prevalence of hospital infection in the top three surgical ICU, integrated ICU, dry three subjects; 2014 elderly hospitalized patients related to equipment (ventilator, central venous plug Tubes and catheters) were 20.96 ‰, 5.60 ‰ and 5.33 ‰, respectively; in 2015 they were 27.63 ‰, 2.16 ‰ and 6.01 ‰, respectively. Conclusion Elderly hospitalized patients are at high risk of nosocomial infection, and their surveillance is strengthened. Effective prevention and control measures are taken to control nosocomial infection in elderly hospitalized patients, which can effectively reduce nosocomial infection.
