Analysis of Risk Facters of Acinetobacter Nosocomial Lower Respiratery Tract Infection

目的 :探讨医院下呼吸道不动杆菌感染的危险因素。方法 :采用 1∶1配对病例对照研究。结果 :条件Logisitic回归结果显示 :住院天数、糖尿病、呼吸机和使用激素为医院下呼吸道不动杆菌感染的危险因素 ,OR值分别是 :1 0 3,2 2 2 1,14 12 ,5 16 ,95 %CI均大于 1。结论 :加强对相关危险因素的控制 。

Objective:To explore the risk facters that cause ANRI.Methods:1∶1 metched case-contral study was carried out.Results:Conditional Logistic regression results indicate that admission days,diabetes,respirator and hormone were the risk facters of ANRI.OR values were 1 03,22 21,14 12 and 5 16 respectively.95% CI of the four facters were greater than 1.Conclusions:it is and effective method to prevent ANRI by strengthen the control of the risk facters.
