Multicenter Study
Vital Signs Are Not Associated with Self-Reported Acute Pain Intensity in the Emergency Department.
This study aimed to ascertain the association between self-reported pain intensity and vital signs in both emergency department (ED) patients and a subgroup of patients with diagnosed conditions known to produce significant pain. ⋯ Health care professionals cannot use vital signs to estimate or substantiate self-reported pain intensity levels or changes over time.

Multicenter Study
National survey of emergency physicians for transient ischemic attack (TIA) risk stratification consensus and appropriate treatment for a given level of risk.
Five percent of transient ischemic attack (TIA) patients have a subsequent stroke within 7 days. The Canadian TIA Score uses clinical findings to calculate the subsequent stroke risk within 7 days. Our objectives were to assess 1) anticipated use; 2) component face validity; 3) risk strata for stroke within 7 days; and 4) actions required, for a given risk for subsequent stroke. ⋯ A validated Canadian TIA Score will likely be used by emergency physicians. Most components of the TIA Score have high face validity. Risk strata are definable, which may allow physicians to determine immediate actions, based on subsequent stroke risk, in the emergency department.

Randomized Controlled Trial Multicenter Study
Targeted temperature management: It is not yet time to change your target temperature.
Clinical question In unconscious patients of out-of-hospital cardiac arrest, does targeted temperature management to 36°C (96.8°F) improve outcomes compared to the standard target of 32°C-34°C (89.6°F-93.2°F)? Article chosen Nielson N, Wetterslev J, Cronberg T, et al. Targeted temperature management at 33°C versus 36°C after cardiac arrest. N Engl J Med 2013;369:2197-2206. ⋯ To determine which temperature, 33°C (91.4°F) or 36°C (96.8°F), is associated with lower mortality and better neurologic function after cardiac arrest.

National Survey of Emergency Physicians to Define Functional Decline in Elderly Patients with Minor Trauma.
There are a number of screening tools to predict return to the emergency department (ED) in elderly trauma patients, but none exist to specifically screen for functional decline after a minor injury. The objective of this study was to identify outcome measures for a possible future clinical decision rule to be used in the ED to identify previously independent patients at high risk of functional decline at six months post minor injury. ⋯ A drop of three points on the 28-point OARS ADL Scale would be deemed clinically important by the vast majority of emergency physicians. Further, a sensitivity of 93% for a clinical decision tool would satisfy the MCID requirements of the vast majority of emergency physicians. There appears to be a gap between physician knowledge and actual practice. We intend to use these findings in the development of a clinical decision rule to identify high-risk elderly trauma patients.

Multicenter Study
Isolated transient aphasia at emergency presentation is associated with a high rate of cardioembolic embolism.
A cardiac source is often implicated in strokes where the deficit includes aphasia. However, less is known about the etiology of isolated aphasia during transient ischemic attack (TIA). Our objective was to determine whether patients with isolated aphasia are likely to have a cardioembolic etiology for their TIA. ⋯ Isolated aphasia is associated with a high rate of cardioembolic sources of embolism after TIA. Emergency patients with isolated aphasia diagnosed with a TIA warrant a rapid and thorough assessment for a cardioembolic source.
