Investigation of the neurologically intact (ie, no neurologic deficits) patient with headache is a potentially difficult clinical decision for physicians.2][3][4] Although to evaluate patients new deficits relatively straightforward, it much more determine which alert, who present alone require investigations-yet such account half all subarachnoid hemorrhages at initial presentation. 5This diagnostic dilemma illustrated by report that 5.4% confirmed were misdiagnosed during patients'...

Patients leaving the emergency department (ED) without being seen (LWBS) by a physician have become growing concern in overcrowded EDs. The purpose of this study was to determine acuity level, reasons, and outcomes LWBS cases.LWBS patients (or their guardians) from two linked Canadian EDs (one adult, one pediatric), identified during 11 sampling periods seven days' duration each, were contacted telephone. Descriptive statistics are provided.A total 711 (4.5%) 15,660 registered left (50%...

Triage liaison physicians (TLPs) have been employed in overcrowded emergency departments (EDs); however, their effectiveness remains unclear.To evaluate the implementation of TLP shifts at an academic tertiary care adult ED using comprehensive outcome reporting.A six-week clinical research project was conducted between December 9, 2005, and February 2006. A deployed for nine hours (11 AM to 8 PM) daily initiate patient management, assist triage nurses, answer all medical consult or transfer...

Abstract Background Emergency department (ED) triage prioritizes patients on the basis of urgency need for care. eTRIAGE is a Web‐based decision support tool that based Canadian Triage and Acuity Scale (CTAS), five level system (CTAS 1 = resuscitation, CTAS 5 nonurgent). Objectives To examine validity resource utilization cost as measures acuity. Methods Scores CTAS, specialist consultations, computed‐tomography use, ED length stay, disposition, estimated hospital costs (if patient was...
