Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Delirium occurs in 10% of older emergency department (ED) patients, yet it remains poorly understood. To date, the predominance of delirium studies have been conducted in hospitalized patients and therefore have limited generalizability to the ED. Understanding ED delirium's natural course and its effect on outcomes is not well characterized. The investigators hypothesize that a significant proportion of patients who are delirious in the ED will remain delirious in the hospital, and persistent cases of ED delirium will be significantly associated with higher 6-month mortality and accelerated functional decline. To test this hypothesis, the investigators will perform a prospective cohort study that will enroll 150 older ED patients with delirium and a random selection of 150 older ED patients without delirium; both groups will comprise of admitted ED patients only. Once enrolled in the ED, the investigators will assess patients for 7 days during hospitalization and perform phone follow-up at 6-months.
