目的研究小儿内科医院感染的相关危险因素,为控制医院感染提供依据。方法回顾性分析2010年1月-2014年6月小儿内科3 063例患儿临床资料,采用单因素、多因素logistic回归分析发生医院感染的危险因素,数据采用SPSS17.0软件进行处理。结果小儿内科3 063例患儿中发生医院感染1 021例,感染率33.33%;单因素分析结果显示,小儿内科患儿住院时间>14d、有中心静脉插管、留置胃管、白血病、肺炎、恶性肿瘤等的感染率,分别为57.37%、96.43%、76.12%、58.17%、49.34%、42.60%,其与医院感染的发生存在密切相关性,差异有统计学意义(P<0.05);多因素分析结果显示,住院天数、中心静脉插管、留置胃管、白血病、肺炎及恶性肿瘤是小儿内科患儿发生医院感染的独立危险因素。结论小儿内科患儿感染与住院时间、白血病及侵入性操作等相关,针对相关因素采取相应的防护措施,以降低感染率。
Objective To study the related risk factors of nosocomial infection in pediatrics and provide basis for controlling nosocomial infection. Methods The clinical data of 3 063 pediatric patients from January 2010 to June 2014 were retrospectively analyzed. The risk factors of nosocomial infection were analyzed by single factor and multivariate logistic regression. The data were processed by SPSS17.0 software. Results 1 021 cases of nosocomial infection occurred in 3 063 pediatric patients and the infection rate was 33.33%. The results of univariate analysis showed that the pediatric internal medicine patients were hospitalized for> 14 days, with central venous catheterization, gastric tube indwelling, leukemia, pneumonia, The infection rate of malignant tumor was 57.37%, 96.43%, 76.12%, 58.17%, 49.34% and 42.60% respectively. There was a close correlation between the infection rate and the incidence of nosocomial infection (P <0.05) The results of factor analysis showed that hospitalization days, central venous catheterization, gastric tube indwelling, leukemia, pneumonia and malignant tumor were independent risk factors for nosocomial infection in children. Conclusion The pediatric internal medicine infection in children is related to the length of hospital stay, leukemia and invasive procedures, and corresponding protective measures are taken to reduce the infection rate.
