摘　　要：目的通过调查住院患者医院感染特点及相关危险因素,为科学干预医院感染发生提供参考。方法采用回顾性分析法调查我院2018年全年94635例住院患者的临床资料,了解医院感染的特点,同时采用单因素分析和多因素logistic回归分析研究发生医院感染的危险因素。结果发生医院感染2211例,感染率为2.34%,以下呼吸道感染为主;2531例医院感染中共培养出病原菌1004株,以革兰阴性菌为主;患者年龄、住院天数、呼吸机使用和合并肿瘤是该院发生医院感染的独立危险因素(P<0.05)。结论我院2018年医院感染发生率控制良好,通过对医院感染的高危因素进行了深入研究得出住院时长>31 d、使用呼吸机的住院患者发生医院感染风险较高。由于医院感染的发生涉及的因素与环节众多,临床上应针对危险因素采取科学有效的干预及防控措施,减少医院感染的发生。Objective By investigating the characteristics and related risk factors of nosocomial infections,it provides a reference for scientific intervention of nosocomial infections.Methods Retrospective analysis was used to investigate the clinical data of 94635 hospitalized patients in 2018 to understand the characteristics of nosocomial infections.Meanwhile,univariate analysis and multivariate logistic regression analysis were used to study the risk factors of nosocomial infections.Results Two thousand two hundred and eleven patients were infected nosocomial infections and the infection rate was 2.34%;The main infection site was lower respiratory tract;In the 2531 times hospital infections,1004 strains of pathogens were cultured.Among all pathogens,the top one was Acinetobacter baumannii;The age of patients,hospitalization days,ventilator use of the hospitalized patients and the complication of tumor were the independent risk factors for nosocomial infections in the hospital(P<0.05).Conclusions The incidence rate of nosocomial infection in our hospital in 2018 was well controlled.Through in-depth research on the high risk factors of nosocomial infection,it was concluded that the risk of nosocomial infection was higher in the inpatients who stayed in hospital longer than 31 days or used ventilators.Due to the numerous factors and links involved in the occurrence of nosocomial infection,scientific and effective intervention and prevention and control measures should be taken clinically for risk factors to reduce the occurrence of nosocomial infection.
