Observational Study
The Diagnostic Performance of the Richmond Agitation Sedation Scale for Detecting Delirium in Older Emergency Department Patients.
Delirium is frequently missed in older emergency department (ED) patients. Brief (<2 minutes) delirium assessments have been validated for the ED, but some ED health care providers may consider them to be cumbersome. The Richmond Agitation Sedation Scale (RASS) is an observational scale that quantifies level of consciousness and takes less than 10 seconds to perform. The authors sought to explore the diagnostic accuracy of the RASS for delirium in older ED patients. ⋯ In older ED patients, a RASS other than 0 has very good sensitivity and specificity for delirium as diagnosed by a psychiatrist. A RASS > +1 or < -1 is nearly diagnostic for delirium, given the very high positive likelihood ratio.

The emergency department (ED) is increasingly used by patients with life-limiting illness. These patients are frequently admitted to the hospital, where they suffer from poorly controlled symptoms and are often subjected to marginally effective therapies. Palliative care (PC) has emerged as the specialty that cares for patients with advanced illness. PC has been shown to reduce symptoms, improve quality of life, and decrease resource utilization. Unfortunately, most patients who could benefit from PC are never identified. At present, there exists no validated screening tool to identify significant unmet PC needs among ED patients with life-limiting illness. ⋯ Use of a modified Delphi technique resulted in the creation of a content-validated screening tool for identification of ED patients with significant unmet PC needs. Further validation testing of the instrument is warranted.

Concussion is the most common type of mild traumatic brain injury for which patients present to the emergency department (ED). It is critical to understand the contemporary epidemiology of concussion and rates of head computed tomography (CT) use in head-injured patients to inform education of evidence-based clinical practice guidelines to emergency medicine providers. ⋯ ED visits for concussions have increased over time, with a corresponding increase in head CT utilization despite a decrease in injury severity. Increased visits may be due to more concussion awareness and recognition of subtle injuries. Evidence-based clinical practice guidelines for neuroimaging in head-injured patients and management of concussion should be reinforced to emergency medicine providers.

Target-specific anticoagulants such as rivaroxaban facilitate immediate discharge of low-risk venous thromboembolism (VTE; including deep vein thrombosis [DVT] and pulmonary embolism [PE]) allowing treatment at home instead of hospitalization. ⋯ Cost of medical care was lower for low-risk VTE patients discharged immediately from the ED with rivaroxaban therapy compared with patients treated with LMWH-warfarin.
