Abstract:
Objective To investigate the risk factors of ICU delirium in critically ill patients. Methods A total of 1 74 critically ill patients in ICU who were older than 18 yrs and stayed in ICU exceeding 24 hs from January 201 5 to June 201 5 were enrolled.Patients were divided into delirium group and non delirium group.Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM-ICU)during the first 7 days.The factors such as history of alcoholism and other 12 factors were analyzed by univariate and multivariate logistic regression analysis to identify those risk factors associated with delirium.Results With 22 cases of delirium in 1 74 patients,the in-cidence of delirium was 12.64% (delirium group).Variables associated with delirium were coronary heart history,operation,tracheal intubation,clinical use of mechanical ventilation,hypoxemia and Benzodiazepine.Multivariate logistic regression analysis showed that coronary heart disease (OR 3.932,95%CI 1.225-12.61 7),surgery(OR 9.691,95%CI 2.103-44.657),hypoxemia(OR 6.595, 95%CI 1.377-31.585),Benzodiazepine use (OR 7.620,95%CI 1.713-33.899)was independent risk factors of delirium in critically ill patients (P < 0.05 or P < 0.01 ).Conclusion Coronary heart disease,surgery,hypoxemia and Benzodiazepine are independent risk factors of ICU delirium in criti-cally ill patients.Early screening and prevention of delirium should be given to reduce the occurrence of delirium for patients in ICU.
