2015-2020年某三甲专科医院医院感染现患率调查

Investigation of the prevalence rate of infection in a tertiary specialized hospital from 2015 to 2020

目的调查2015-2020年某三甲专科医院感染现患率、抗菌药物使用及病原学送检等情况,了解医院感染的变化趋势,为医院感染防控提供科学依据。方法采用横断面调查方法,分别选取2015-2020年的某一天为调查日,对当天住院患者的感染情况进行调查,分析连续6年医院感染现状。结果共调查患者7654例,医院感染137例,共142例次,医院感染现患率1.79%,例次现患率1.85%。下呼吸道其中医院感染居多部位占首位的为下呼吸道,医院感染现患率最高的科室为两个重症医学科(ICU),分别为14.71%和7.29%。6年抗菌药物的使用率为22.24%~34.59%,2018年和2019年使用率最低(χ^(2)=61.881,P<0.05);病原学送检率由50.47%上升至75.63%(χ^(2)=62.691,P<0.05)。结论抗菌药物使用率和病原学送检率管理成效显著,有助于医院感染控制的改进,ICU医院感染现患率最高,是医院感染控制的重点部门。

Objective To investigate the prevalence rate of nosocomial infection,the use of antibacterial drugs and their pathogenic inspections from 2015 to 2020 in a tertiary hospital,in order to understand the changing trend of nosocomial infection,and to provide scientific basis for the prevention and control of nosocomial infection.Methods A cross-sectional survey was conducted to investigate the infection status of all patients in the hospital one day in July or August 2015-2020.Results A total of 7654 hospitalized patients were investigated,the nosocomial infection rate was 1.79%and 1.85% in 137 patients and 142 times.The main site of nosocomial infection was upper respiratory tract.The highest infection rate were 14.71% and 7.29% in two intensive care units(ICU).The utilization rates of antibiotics were 22.24%-34.59% in the past six years,with the lowest use rate in 2018 and 2019.The pathogenic examination rate increased from 50.47% to 75.63%(χ^(2)=62.691,P<0.05).Conclusion The utilization rate of antibiotics and the rate of pathogen examination are effective,which is helpful to the improvement of hospital infection control.ICU,which has the highest rate of hospital infection,is the key department of hospital infection control.
