Analysis on characteristics of delirium among neurosurgery intensive care unit patients

Abstract

Objective To explore the incidence of delirium among Neurosurgery Intensive Care Unit (ICU) patients and analyze the characteristics of delirium. Methods This study carried out perspective cohort study design. From May 2016 to July 2017, we selected 150 Neurosurgery ICU patients of a ClassⅢ Grade A hospital by convenience sampling as respondents. Delirium was evaluated with the Confusion Assessment Method for the ICU (CAM-ICU) daily. Logistic regression was used in data analysis to analyze the related risk factors of delirium. Results The incidence of delirium of was 42% in those patients. Types of delirium were main in the type of increasing activity accounting for 36.5%. There were 57.1% of patients with delirium two to five days after being admitted to ICU. Logistic regression analysis showed that the independent predictors of delirium of Neurosurgery ICU patients were Acute Physiology, Age, Chronic Health EvaluationⅡ (APACHEⅡ) (OR=0.901, 95% CI 0.813-0.998) , physical restraint (OR=11.382, 95% CI 3.616-35.826) , hypoproteinemia (OR=6.102, 95% CI 1.729-21.530) . Conclusions The incidence of delirium is high in Neurosurgery ICU patients. There are many risk factors inducing delirium of patients. We should closely pay attention to patients' mental state so as to early take effective measures to prevent delirium. Key words: Delirium; Intensive care; Risk factors; Neurosurgery
