Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 6-month mortality and functional status.

    We will perform 6-month phone follow-up to ascertain death and functional status.

    6-months

  • Emergency department delirium duration

    Patients will be enrolled in the emergency department and will be assessed for delirium daily until hospital day #7 or hospital discharge.

    Until hospital discharge or the first 7-days of hospitalization.

Study Arms (2)

Delirious in the ED

Patients who were delirious in the ED at either the 0-hour or 3-hour delirium assessment.

Non-Delirious in the ED

Patients who were non-delirious in the ED at both the 0-hour or 3-hour delirium assessment.
