Delirium is a widespread and serious but under-recognized problem. Increasing evidence argues that emergency health care providers need to assess the mental status of the patient as the "sixth vital sign". A simple, sensitive, time-efficient, and cost-effective tool is needed to identify delirium in patients in the emergency department (ED); however, a stand-alone measurement has not yet been established despite previous studies partly because the differential diagnosis of dementia and delirium superimposed on dementia (DSD) is too difficult to achieve using a single indicator. ⋯ For instance, we proposed the 100 countdown test as an effective means of detecting inattention. Further dedicated studies are warranted to shed light on the pathophysiology and better management of dementia, delirium and/or "altered mental status". We reviewed herein the clinical questions and controversies concerning delirium in an ED setting.

Trauma patients often present with injuries requiring resuscitation and further evaluation. Many providers advocate for whole body computed tomography (WBCT) for rapid and comprehensive diagnosis of life-threatening injuries. ⋯ While observational data suggests an association between WBCT and a benefit in mortality and ED length of stay, randomized controlled data suggests no mortality benefit to this diagnostic tool. The literature would benefit from confirmatory studies of the use of WBCT in trauma sub-groups to clarify its impact on mortality for patients with specific injury patterns.

Chest pain accounts for a significant percentage of emergency department (ED) presentations. The HEART score and pathway have demonstrated an ability to appropriately risk stratify and discharge from the ED a significant proportion of patients. ⋯ Appropriate use of the HEART pathway reliably risk stratifies patients. Physicians must consider several key components when utilizing the HEART pathway, and future directions may incorporate other patient factors.
