Delirium and Associated Factors Among Older Patients in Coronary and Internal Medicine Intensive Care Units of a University Hospital
Journal Title: European Journal of Geriatrics and Gerontology - Year 2019, Vol 1, Issue 3
Abstract
Objective: Delirium in intensive care units (ICUs) is associated with increased mortality, cognitive decline, prolonged hospitalization and increased likelihood of discharge to nursing home. Therefore, we aimed to evaluate its prevalence and the associated risk factors in two ICUs. Materials and Methods: In this cohort study, delirium frequency was evaluated among 100 patients aged 65 and over in the internal medicine and coronary ICUs of Süleyman Demirel University Faculty of Medicine using the confusion assessment method and daily evaluations during May-June 2015. Cognitive and functional evaluations were performed and socio-demographic and clinical characteristics were recorded. Results: Overall, delirium prevalence was 15% and it was more common in the internal medicine ICU compared to coronary ICU (52% vs 2.7%). In univariate analysis, age and Charlson comorbidity index and eight-item ‘’Informant Interview to Differentiate Aging and Dementia’’ (AD8) scores were higher and Barthel activities of daily living index, Lawton-Brody instrumental activities of daily living scale and mini-mental state examination scores were lower in delirious patients. In multivariate logistic regression analysis, Barthel index was the only independent predictor of delirium. Barthel, Lawton-Brody, mini-mental state examination and AD8 scores were different among patients in the internal medicine ICU and those in coronary ICU. Conclusion: Delirium and its risk factors were observed more frequently among internal medicine ICU patients. Moreover, activities of daily living score was the strongest predictor of delirium risk.
