神经内科医院感染的发生及其相关危险因素分析

Hospital infection and its associated risk factors analysis at department of neurology

目的分析本院神经内科住院患者的院内感染情况,探讨神经内科患者院内感染的发生及相关危险因素。方法回顾性分析本院2008年3月至2012年3月874例神经内科住院患者的临床资料,采用连续病例监测、单因素分析以及Logistic回归模型多因素分析方法对院内感染的相关危险因素进行分析。结果 874例患者中共有45例出现了院内感染,感染率高达5.1%;Logistic回归分析结果显示,神经内科住院患者院内感染的重要危险因素为冬春季节发病、年龄>60岁、吸烟饮酒生活史、糖尿病史、住院时间>20天、昏迷、应用广谱抗生素、气管插管或切开、机械通气、留置导尿。结论神经内科住院患者的院内感染概率较大,引发感染的相关因素较多而复杂,应采用综合防治措施控制神经内科患者住院期间院内感染率。

Objective To investigate the status of hospital infection at the department of neurology and analyze the related risk factors. Methods Eight hundred and seventy-four in-patients at the department of neurology in our hospital during March 2008-March 2012 were retrospectively analyzed. Single factor analysis and Logistic regression model were used to analyze related risk factors with infection. Results In the 874 in-patients there was a total of 45 cases was found to be infected. The infection rate was 5.1%. Statistical analysis showed that infection related risk factors included spring-winter seasons, age older than 60 years old, smoking/drinking life history, history of diabetes, length of hospital stay more than 20 days, exanimatum, broad-spectrum antibiotics, endotracheal intubation or incision, mechanical ventilation, and indwelling catheterization. Conclusions The in-patients at department of neurology have a high rate of hospital infection, and related risk factors were complicated. Therefore, the comprehensive prevention and control measures should be applied in order to control the infection effectively.
