某老年医院2013年～2016年医院感染现患率调查分析

Survey and analysis on the prevalence rate of nosocomial infection in a geriatric hospital during 2013-2016

目的调查某老年医院患者医院感染情况及变化趋势,为医院感染管理提供参考依据。方法采用床旁调查和查阅病历相结合的方法,对2013年~2016年某老年医院住院患者进行医院感染现患率调查。结果 2013年~2016年医院感染现患率分别为1.61%、3.61%、4.34%、5.42%。感染部位均以下呼吸道居首位,其次为泌尿道、上呼吸道等。医院感染病原体均以革兰阴性菌为主,且以铜绿假单胞菌检出最多。2013年~2016年医院感染病原体阳性检出率分别为7.84%、21.57%、39.02%、34.04%。结论连续4年的医院感染现患率调查,真实反映了老年医院感染的现状,发现了医院感染的高发部位和高危科室,也提示了在今后的工作中,医院感染及多重耐药菌的预防控制不容忽视。

Objective The paper aims to make an investigation into the nosocomial infection of patients and its change trend in a geriatric hospital in order to provide reference basis for the management of nosocomial infection. Method The combination of bedside investigation and medical record reference was adopted in the survey on the prevalence rate of nosocomial infection of inpatients in a geriatric hospital from 2013 to 2016. Result The prevalence rates of nosocomial infection from 2013 to 2016 were 1.61%, 3.61%, 4.34%, and 5.42%, respectively. Lower respiratory tract always topped the list of infection sites, followed by urinary tract and upper respiratory tract. The pathogens of nosocomial infection were mainly Gram-negative bacteria, and the detected number of Pseudomonas aeruginosa was the biggest. The positive detection rates of nosocomial infection pathogens from 2013 to 2016 were 7.84%, 21.57%, 39.02%, and 34.04%, respectively. Conclusion The survey on the prevalence rates of nosocomial infection in 4 consecutive years truly reflected the status quo of nosocomial infection in the geriatric hospital, found out the high-incidence sites and high-risk departments of nosocomial infection, and indicated that the prevention and control over nosocomial infection and multi-drug resistant bacteria could not be ignored in the future work.
