ABSTRACTIntroduction:Drowning is a major public health concern, yet little is known about the characteristics of drowning patients. The objectives of this study were to describe the demographic and clinical characteristics of out-of-hospital cardiac arrest (OHCA) attributed to drowning in Ontario and to compare the characteristics of OHCA attributed to drowning to those of presumed cardiac etiology. Methods:A retrospective, observational study was carried out of consecutive OHCA patients of drowning etiology in Ontario between August 2006 and July 2011. ⋯ Conclusions:Significant differences exist between OHCA of drowning and presumed cardiac etiologies. Most drownings are unwitnessed, occur in public locations, and present with nonshockable initial rhythms, suggesting that treatment should focus on bystander CPR. Future initiatives should focus on strategies to improve supervision in targeted locations and greater emphasis on bystander-initiated CPR, both of which may reduce drowning mortality.

ABSTRACTBackground:Cardiac troponin elevation portends a worse prognosis in diverse patient populations. The significance of troponin elevation in patients discharged from emergency departments (EDs) without inpatient admission is not well known. Methods:Patients without a diagnosis of acute coronary syndrome discharged from two EDs between April 1, 2006, and December 31, 2007, with an abnormal cardiac troponin (troponin positive [TP]) were compared to a troponin-negative (TN) cohort matched for age, sex, and primary discharge diagnosis. ⋯ There was no significant difference in death (OR 1.3, 95% CI 0.6-2.9, p = 0.5) after adjustment. Conclusions:A positive troponin assay during ED stay in discharged patients is an independent marker of risk of subsequent admission. Our findings suggest that the prognostic power of an abnormal troponin extends to patients discharged from the ED.

ABSTRACTObjective:Despite evidence that patients suffering major traumatic injuries have improved outcomes when cared for within an organized system, the extent of trauma system development in Canada is limited. We sought to compile a detailed inventory of trauma systems in Canada as a first step toward identifying opportunities for improving access to trauma care. Methods:We distributed a nationwide online and mail survey to stakeholders intended to evaluate the extent of implementation of specific trauma system components. ⋯ Conclusion:There is significant variability in the extent of trauma system development in Canada. Although all provinces have designated trauma centres, opportunities exist in many systems to implement additional components to improve the inclusiveness of care. In future work, we intend to quantify the strength of the relationship between different trauma system components and access to definitive trauma care.

ABSTRACTObjectives:Blood glucose can be lowered via insulin and/or fluid administration. Insulin, although efficacious, can cause hypoglycemia and hypokalemia. Fluids do not cause hypoglycemia or hypokalemia, but the most effective route of fluid administration has not been well described. ⋯ No adverse events were observed in either group. Conclusion:In this unblinded randomized trial, oral and intravenous fluids were equally efficacious in lowering blood glucose levels in stable hyperglycemic patients and no adverse events were noted. Physicians should be mindful that, although similar, the reduction in blood glucose was modest in both groups.
