某三甲综合医院2019-2021年医院感染现患率调查分析

Investigation and analysis on the prevalence rate of nosocomialinfection in a third class general hospital from 2019 to 2021

目的探讨某三甲综合医院2019-2021年医院感染现患率调查结果,为进一步降低和控制院内感染情况提供理论依据.方法使用横断面的调查方法对揭阳市某三甲综合医院2019-2021年医院感染情况进行实时监控,并进行数据收集,整理和分析.结果该研究中2019年-2021年共调查5251例住院患者(男性2853例,女性2398例),其中院感病例数49例(男性28例,女性21例),院感发生率0.93%.ICU的医院感染现患率最高,为12.70%,其次为外科,为1.03%.下呼吸道是医院感染发生率最高的部位,占48.98%,其次为上呼吸道,占18.37%.医院感染病原菌分布共检出病原菌18株,革兰阴性菌是医院感染中占比最高的病原菌,占医院感染的83.33%,其中,又以鲍曼不动杆菌的发生率最高,占27.78%.动静脉插管、泌尿道插管、慢性病、免疫缺陷、气管切开、使用呼吸机、卧床时间方面≥2周可作为医院感染的独立危险因素(P<0.05).结论使用横断面研究能够真实有效地对医院感染情况进行反映,有助于进一步制定和改善院内感染控制措施.临床上对于接受侵入性操作的患者应进行院内感染防控的重点干预,而革兰阴性菌以及呼吸系统感染是现阶段院内感染的防治重点.

Objective To explore the survey results of the prevalence rate of nosomcioal infection in a third class general hospital fro m 2019 to 2021,so as to provide a theoretical basis for furthere drucing and controlling nosocomial infection.Methods The cross-sectional survey method was used to monitor the nosocomial infection of tahird class general hospital in Jieyang from 2019 to 2021,ancdo llect,sort out and analyze the receipts.Results In this study,a total of 5251 hospitalized patients(2853 masl eand 2398 females)were investigated fro m 2019 to 2021,including 49 cases of nosocomial infection(28 maels and 21 females).The incidence of nosocomial infection was 09.3%.The prevalence rate of nosocomial infection in ICU was the highest,12.70%,followed by surgery,1.03%.The lower respiratory tract is the site with the highest incidence of nosocomial infection,accounting for 48.98%,followed by the upper respiratory tract,accounting for 18.37%.A total of 19 strains of pathogenic bacteria were detected in the distribution of nosocomial infection.Gram negative bacteria accounted for the highest proportion of nosocomial infection,accounting for 83.33%of nooscomial infection.Among them,Acinetobacter baumannii had the hgihest incidence,accounting for 27.78%.Arteriovenous intubation,urinary tract intubation,chronic diseases,immune deficiency,tube incision,use of ventilator and bed rest time≥2 weeks could be regarded as dienpendent risk factors of nosocomial infection P(<0.05).Conclusions The use of cross-sectional study can truly and effectively respond to nosocomial infection,which is helpful to further formulate and improve nosocomial infection control measures.Clinically,the key interevntion of nosocomial infection prevention and control should bcearried out for patients undergoing invasive operation,and the prevention and control of Gram-negative bacteria and respiratory infection are the key points of nosocomial infection at this stage.
