ABSTRACTInfective endocarditis (IE) is a rare but serious condition. We present a case of endocarditis in a healthy 40-year-old male with no predisposing conditions. ⋯ After treatment, he later presented to the emergency department with abdominal pain, and a superior mesenteric artery aneurysm was discovered. We discuss recent advances in the changing epidemiology and microbiology of IE, review the presentation and diagnosis of IE, and highlight the potential complications of this disease.

ABSTRACTObjectives:To describe pediatric emergency medicine (PEM) physicians' reported pain management practices across Canada and explore factors that facilitate or hinder pain management. Methods:This study was a prospective survey of Canadian pediatric emergency physicians. The Pediatric Emergency Research Canada physician database was used to identify participants, and a modified Dillman's Total Design Survey Method was used for recruitment. ⋯ Conclusions:When analgesia was reported as provided, ibuprofen and acetaminophen were most commonly used. Both procedural and presenting pain remained suboptimally managed. There is a substantial evidence practice gap in children's ED pain management, highlighting the need for further knowledge translation strategies and policies to support optimal treatment.

ABSTRACTObjectives:To identify factors known prior to triage that might have predicted hospital admission for patients triaged by the Canadian Triage Acuity Scale (CTAS) as level 5 (CTAS 5, nonurgent) and to determine whether inappropriate triage occurred in the admitted CTAS 5 patients. Methods:We reviewed the triage records of patients triaged as CTAS 5 at the emergency departments (EDs) of three tertiary care hospitals between April 2002 and September 2009. Two triage nurses unaware of the study objective independently assigned the CTAS level in 20% of randomly selected CTAS 5 patients who were admitted. ⋯ Conclusions:Most of the CTAS 5 patients who were subsequently admitted to hospital may have qualified for a higher triage category. Two potential modifiers, age over 65 and arrival by ambulance, may have improved the prediction of admission in CTAS 5 patients. However, the consistent application of existing CTAS criteria may also be important to prevent incorrect triage.

ABSTRACTObjective:Emergency physicians are expected to rule out clinically important cervical spine injuries using clinical skills and imaging. Our objective was to determine whether emergency physicians could accurately rule out clinically important cervical spine injuries using computed tomographic (CT) imaging of the cervical spine. Method:Fifteen emergency physicians were enrolled to interpret a sample of 50 cervical spine CT scans in a nonclinical setting. ⋯ The negative likelihood ratio was 0.18 (95% CI 0.12-0.25). Conclusion:Experienced emergency physicians successfully identified a large proportion of cervical spine injuries on CT; however, they were not sufficiently sensitive to accurately exclude clinically important injuries. Emergency physicians should rely on a radiologist review of cervical spine CT scans prior to discontinuing cervical spine precautions.

ABSTRACTObjectives:Cognitive forcing strategies (CFS) may reduce error arising from cognitive biases. This is the first experimental test to determine the effect of CFS training in medical students. Methods:Students were allocated to CFS training or control during a 4-week emergency medicine rotation (n = 191). ⋯ There were no significant differences between groups (χ2 = 2.38, df = 1, p = 0.12). In the AB cases, only 45% in each group identified the uncommon correct diagnosis (χ2 = 0.001, df = 1, p = 0.98). Conclusions:The educational interventions suggested by experts in clinical reasoning and employed in our study to teach CFS failed to show any reduction in diagnostic error by novices.
