Delirium in the Emergency Department and Its Extension Into Hospitalization (DELINEATE)

상세 설명
Delirium is an acute confusional state characterized by fluctuating mental status, inattention, and either disorganized thinking or an altered level of consciousness. The prevalence of delirium in elderly patients is approximately 10% in emergency department (ED) patients. Several hospital-based studies have shown delirium to be associated with worsening mortality,longer hospital length of stay, higher health care costs,and poorer long-term functional and cognitive function.
However, delirium in the ED remains poorly understood. Specifically, its natural course is not well characterized and represents a critical gap in knowledge. Improving our understanding is paramount for several reasons. If the majority of delirium persists beyond the ED and is associated with long-term adverse outcomes, then routine delirium surveillance in the busy ED environment can be justified. Understanding the natural course may also help physicians identify delirious patients at highest risk for adverse outcomes and would be the focus of future delirium interventions. Lastly, we don't know if all patients with delirium require an admission. Understanding the natural course may help identify delirious patients that can be safely discharged home and those who require a hospital admission.
Given this paucity of data, we are conducting this study with the following specific aims: 1) To describe the frequency in which delirium in the ED persists into hospitalization and determine how patient factors and clinical factors affect delirium persistence. 2) To determine how ED delirium duration affects 6-month outcomes. To achieve these aims, we will perform a prospective cohort study thatwill enroll 125 older ED patients with delirium and a random selection of 125 older ED patients without delirium; both groups will comprise of admitted ED patients only. Once enrolled in the ED, we will assess patients for 7 days during hospitalization and perform phone follow-up at 6-months.
