目的探讨住院患儿合并医院感染的相关因素。方法 2007年5月-2010年5月发生医院感染的42例患儿作为观察组,按照1∶2配比设立对照组,对两组患儿可能引起医院感染的相关变量进行单因素分析与logistic回归分析。结果单因素检验2χt、检验显示,9个变量是引起医院感染的相关因素(P<0.05),与性别构成、体重无关;logistic回归分析,筛选出独立相关因素:年龄小、实施侵入性操作、预防应用抗菌药物、重症监护(参数估计值分别为8.89、8.12、5.98、7.56)差异有统计学意义(P<0.05),OR值分别为3.34、2.79、2.47、2.14。结论住院患儿合并医院感染发生率较高,是多因素综合作用的结果,应针对相关因素采取相应的预防措施。
Objective To investigate the related factors of nosocomial infection in hospitalized children. Methods From May 2007 to May 2010, 42 children with nosocomial infection were selected as the observation group and the control group was established according to the ratio of 1: 2. Univariate analysis and logistic regression analysis were performed on the related variables that may cause nosocomial infection in the two groups. regression analysis. Results One-factor test 2χt showed that 9 variables were the related factors causing nosocomial infection (P <0.05), regardless of sex composition and body weight. Logistic regression analysis showed that independent factors were small age, invasive operation, There were significant differences in the prevention and treatment of antibiotics and intensive care (the estimated parameters were 8.89,8.12,5.98 and 7.56 respectively) (OR = 3.34, 2.79, 2.47, 2.14 respectively). Conclusions The incidence of nosocomial infections in hospitalized children is high, which is the result of multifactorial combination. Relevant preventive measures should be taken according to the relevant factors.
