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.

ABSTRACTObjective:Point-of-care ultrasonography (PoCUS) first appeared in the 1980s in North America, but the extent of the diffusion of its adoption is unknown. We characterized early PoCUS adoption by emergency physicians in Canada and its barriers to use using Rogers' diffusion of innovations theory. Methods:We developed a questionnaire based on a pilot study and literature review to assess past, current, and potential use of PoCUS and potential barriers to adoption. ⋯ Several barriers to PoCUS were identified for part-time emergency physicians and those working in inner-city/urban/suburban settings. Conclusion:This is the first study to determine the state of adoption and barriers to the introduction of PoCUS in Canadian emergency medicine practice. The novel validated ETUDE instrument should be used to evaluate the uptake of PoCUS over time.

ABSTRACTTar burns are primarily an occupational hazard associated with the road paving or roofing industry. Management of tar burns requires safe and effective removal of solidified tar from the skin using a dissolution or emulsifying agent to prevent inflicting further injury and pain. We report a case of a patient with tar burns on 10% of his body surface area involving the lower arms bilaterally and splashes to the facial area. The tar was efficiently removed with Webber Vitamin E Ointment without toxicity, irritation, or other complications.

ABSTRACTOphthalmologic complaints represent approximately 2% of emergency department (ED) visits. Acute vision loss is the most serious of such presentations and requires prompt assessment for a treatable cause. ⋯ We report the case of a previously healthy 33-year-old man who presented to the ED with acute bilateral vision loss that was ultimately diagnosed as central serous retinopathy (CSR), an idiopathic, self-limited condition that typically affects males age 20 to 50 years. This condition is not mentioned in standard emergency medicine textbooks or the emergency medicine literature, and our hope is that our report will serve to illustrate a typical case of CSR and help prompt emergency physicians to consider this diagnosis in the appropriate circumstances.

Clinical questionIn emergency department patients with symptoms suggestive of acute myocardial infarction, is the absolute or relative change of cardiac troponin assays (either high sensitivity or ultrasenstive) more accurate in diagnosing acute myocardial infarction at 1 to 2 hours postpresentation?Article chosenRechlin T, Ifran A, Twerenbold R, et al. Utility of absolute and relative changes in cardiac troponin concentrations in the early diagnosis of acute myocardial infarction. Circulation 2011;124:136-45. ObjectiveTo evaluate the accuracy of new troponin assays in diagnosing acute myocardial events.
