摘　　要：目的 分析消化内科医源性感染现状及影响因素,并建立风险模型.方法 选取2019年1月-2021年12月陆军第七十三集团军医院消化内科患者837例,统计感染率及感染部位,通过细菌培养统计病原菌分布情况,收集一般资料,分析医源性感染的影响因素,并建立风险模型.结果 消化内科患者医源性感染发生率为9.44%(79/837),感染部位主要为下呼吸道26例(32.91%)、上呼吸道20例(25.32%)、胃肠道17例(21.52%),病原菌由66.99%的革兰阴性菌、33.01%的革兰阳性菌构成,年龄、住院时间、合并糖尿病、手术、侵入性操作、每日探视人员数量、营养不良、消化内镜消毒时间、消化内镜零部件拆卸冲洗是消化内科医源性感染的影响因素(P<0.05),建立风险模型logit(P)=-11.546+年龄×1.152+住院时间×1.165+合并糖尿病×0.762+手术×1.526+侵入性操作×1.354+每日探视人员数量×1.183+营养不良×1.055+消化内镜消毒时间×1.108-消化内镜零部件拆卸冲洗×1.015,拟合效果良好.结论 消化内科存在明显医源性感染风险,年龄、合并糖尿病、住院时间、侵入性操作、手术、每日探视人员数量、营养不良、消化内镜消毒时间等因素均会增加感染风险,消化内镜零部件拆卸冲洗会降低感染风险,临床应积极关注上述因素,制定干预策略,预防医源性感染.Objective To analyze the current situation and influencing factors of iatrogenic infection in gastroenterology department,and establish a risk model.Methods From January 2019 to Decemher 2021,837 patients in the Department of Gastroenterology in our hospital were selected,the infection rate and infection site were counted,the distribution of pathogenic bacteria was counted by bacterial culture,general data were collected,the influencing factors of iatrogenic infection were analyzed,and the risk was established.Results The incidence of iatrogenic infection in gastroenterology patients was 9.44%(79/837).The infection sites were mainly lower respiratory tract in 26 cases(32.91%),upper respiratory tract in 20 cases(25.32%),and gastrointestinal tract in 17 cases(21.52%),the pathogenic bacteria consisted of 66.99%of gram-negative bacteria and 33.01%of gram-positive bacteria,age,hospital stay,diabetes mellitus,surgery,invasive procedures,number of daily visitors,malnutrition,digestive endoscope disinfection time,digestion Disassembly and flushing of endoscope parts were the influencing factors of iatrogenic infection in gastroenterology(P<0.05),and a risk model was established logit(P)=-11.546+age×1.152+hospital time×1.165+diabetes×0.762+surgery×1.526+Invasive operation×1.354+number of daily visitors×1.183+malnutrition×1.055+digestive endoscope disinfection time×1.108-digestive endoscope parts disassembly and washing×1.015,the fiing effect is good.Conc lus ion There is obvious risk of iatrogenic infection in the department of gastroenterology.Factors such as age,diabetes,hospital stay,invasive operation,surgery,number of daily visitors,malnutrition,and disinfection time of digestive endoscope willincrease the risk of infection.Disassembly and flushing of components will reduce the risk of infection.Clinicians should actively pay attention to the above factors and develop intervention strategies to prevent nosocomial infections.
