The authors previously derived a clinical decision rule (CDR) for chest radiography in patients with chest pain and possible acute coronary syndrome (ACS) consisting of the absence of three predictors: history of congestive heart failure, history of smoking, and abnormalities on lung auscultation. The aim of the investigation was to prospectively validate and refine the CDR for chest radiography in an independent patient population. ⋯ Prospective validation of our previously derived CDR for clinically important chest radiographic abnormalities was not successful. Derivation of a refined rule identified all clinically important radiographic abnormalities, but was insufficiently specific. No CDR with adequate sensitivity and specificity could be found.

Practice patterns in asthma discharge pharmacotherapy in pediatric emergency departments: a pediatric emergency research Canada study.
The objective was to examine utilization of β2 agonists via metered dose inhalers with oral and inhaled corticosteroids (ICS) at discharge in children with acute asthma. ⋯ The overwhelming majority of children discharged from Canadian pediatric EDs with acute asthma are prescribed inhaled albuterol via MDIs. Although the corticosteroid use at discharge is higher than previously reported, utilization of new prescriptions for ICS may not be optimal. Children presenting during daytime to EDs receiving intensive stabilization are more likely to receive the albuterol/oral steroid/ICS combination.

Patient understanding of emergency department discharge instructions: where are knowledge deficits greatest?
Many patients are discharged from the emergency department (ED) with an incomplete understanding of the information needed to safely care for themselves at home. Patients have demonstrated particular difficulty in understanding post-ED care instructions (including medications, home care, and follow-up). The objective of this study was to further characterize these deficits and identify gaps in knowledge that may place the patient at risk for complications or poor outcomes. ⋯ Patients demonstrate the most frequent knowledge deficits for home care and return instructions, raising significant concerns for adherence and outcomes.

The current state of ultrasound training in canadian emergency medicine programs: perspectives from program directors.
There is a paucity of data about emergency ultrasound (EUS) training in emergency medicine (EM) residency programs accredited by the Royal College of Physicians and Surgeons of Canada (Royal College) and the College of Family Physicians of Canada (CFPC). Historically the progress of EUS in Canada has been different from that in the United States. We describe the current state of EUS training in both Royal College and CFPC-EM programs. ⋯ EUS training in Canadian EM programs is prevalent, but there are considerable discrepancies among residency programs in scope of training, curricula, determination of proficiency, and quality assurance. These findings suggest variability in both the level and the quality of EUS training in Canada.

The regionalization of medical services has resulted in improved outcomes and greater compliance with existing guidelines. For certain "time-critical" conditions intimately associated with emergency medicine, early intervention has demonstrated mortality benefits. For these conditions, then, appropriate triage within a regionalized system at first diagnosis is paramount, ideally occurring in the field by emergency medical services (EMS) personnel. Therefore, EMS ground transport access is an important metric in the ongoing evaluation of a regionalized care system for time-critical emergency services. To our knowledge, no studies have demonstrated how methodologies for calculating EMS ground transport access differ in their estimates of access over the same study area for the same resource. This study uses two methodologies to calculate EMS ground transport access to trauma center care in a single study area to explore their manifestations and critically evaluate the differences between the methodologies. ⋯ Based on these results, the authors believe that future methodologies for calculating EMS ground transport access must incorporate a continuous and valid route through the road network as well as use travel speeds appropriate to the road segments traveled; alternatively, we feel that variation in methods for calculating road distances would have little effect on realized access. Overall, as more complex models for calculating EMS ground transport access become used, there needs to be a standard methodology to improve and to compare it to. Based on these findings, the authors believe that this should be the RM.
