Patients meeting inclusion and exclusion criteria.

Kaplan-Meier survival curves in older emergency department patents stratified by delirium and nursing home status. In the Cox proportional hazard regression model, the “delirium*nursing home” interaction was non-significant (p=0.86), delirium in the ED’s effect on 6-month mortality was similar in nursing home and non-nursing home patients.

Kaplan-Meier survival curves in older emergency department patents with and without delirium. Hazard ratio of delirium on 6-month mortality is (HR = 1.72, 95% CI: 1.04 – 2.86) adjusted for age, dementia, functional dependence, comorbidity burden, severity of illness, hearing impairment, and nursing home residence. This indicates that older emergency department patients with delirium are 67% more likely to die compared to those patients without delirium.
