Abstract:
The purposes of this descriptive study research were to study the rate of delirium in older persons at emergency department and examine the relationships between factors related to delirium in older persons at emergency department which were Cognitive impairment, History of stroke, emergency department Length of stay, pain, intracranial hemorrhage and depression. Data were collected from 220 older persons. Who were according to the specified qualifications. Research instruments were demographic questionnaires, 4 As Test for Delirium Screening: 4AT, Informant Questionnaire on Cognitive Decline in the Elderly, IQCODE, Numeric rating scale: NRS. And Pain assessment in advanced dementia, PAINAD. Which were tested for reliability. Cronbachs alpha coefficient were .83, .79 respectively. test-retest procedure reliability were .77, .97 respectively. Data were analyzed by using statistic methods. Including mean, percentage, standard deviation, Chi-square, Point biserial correlation coefficient and binary logistic regressionMajor findings were as follows.1. delirium in older persons at emergency department are 34 people from the total sample size of 220 people. Representing 15.45 percent2. Cognitive impairment, history of stroke, emergency department length of stay, pain, intracranial hemorrhage, and depression were significantly positive correlated with delirium in older persons at emergency department at level of .05 (X2= 9.277, 10.020, rpb= .216, X2= 9.000, 9.568, 3.874 respectively)3. Cognitive impairment (AOR=7.25, 95% CI : 1.681-31.276), History of stroke (AOR=4.74, 95% CI : 1.540-14.579), emergency department Length of stay (AOR=6.67, 95% CI : 2.300-19.337), intracranial hemorrhage (AOR=14.72, 95% CI : 2.637-82.151), and depression (AOR=6.96, 95% CI : 1.274-37.998)were significantly factors predicting delirium in older persons at emergency department at the level of .05 and accounted for 37 percent (Nagelkerke R2 = .370, p < .05).
