Delirium in the Emergency Department: Novel Screening
Aperçu de l'étude

Description détaillée
Delirium is often missed because emergency physicians do not routinely screen for this diagnosis. Most delirium assessments can take up to 10 minutes to perform making them less likely to be incorporated into the routine physician assessment. Using brief (<2 minutes) and easy to use delirium assessments may ameliorate this quality of care issue. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) possesses these characteristics, but has only been validated in mechanically and non-mechanically ventilated intensive care unit patients. Recently, the investigators also developed the Brief Confusion Assessment Method (B-CAM) which is a modification of the CAM-ICU. The benefit is that it takes even less time than the CAM-ICU. The investigators also developed the Emergency Department Delirium Triage Screen (ED-DTS) designed to be highly sensitive and moderately specific delirium assessment for the nurse's triage assessment. It is hypothesized that a negative ED-DTS would rule out delirium, while a positive ED-DTS would require a more formal delirium assessment such as the CAM-ICU and B-CAM. These new delirium assessments require validation in older ED patients. As result, the investigators propose the following and the following specific aims:
Aim #1: To validate the B-CAM in older ED patients. The B-CAM will be performed by a clinical trials associate (CTA) and principal investigator in 200 ED patients that are > 65 years old. This instrument will be validated against a psychiatrist's Diagnostic and Statistical Manual of Mental Disorders, 4th. Edition Text Revision assessment as the reference standard.
Aim #2: To validate the CAM-ICU in older ED patients. The CAM-ICU will be performed by a clinical trials associate (CTA) and principal investigator in approximately 200 ED patients that are > 65 years old. This instrument will be validated against a psychiatrist's Diagnostic and Statistical Manual of Mental Disorders, 4th. Edition Text Revision assessment as the reference standard.
Aim #3: To validate the ED-DTS in older ED patients. The ED-DTS will be performed by a clinical trials associate (CTA) and principal investigator in 200 ED patients that are > 65 years old. This instrument will be validated against a psychiatrist's Diagnostic and Statistical Manual of Mental Disorders, 4th. Edition Text Revision assessment as the reference standard.

Delirium
Délai: Within 3 hours of the study assessments.

Delirium was diagnosed by a consultation-liaison psychiatrist assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria.
The psychiatrists performed a battery of bedside cognitive tests, including (but not limited to) Clock Drawing Test, Luria hand sequencing task, and tests for verbal fluency.
A focused neurological examination (i.e., screening for paraphasic errors, tremors, tone, asterixis, frontal release signs etc.,) and evaluation for affective lability, hallucinations, and level of alertness were also conducted routinely.
Confrontational naming, proverb interpretation or similarities, and assessments for apraxias were performed at the discretion of the reference psychiatrists, especially if the diagnosis of delirium was inconclusive.
