ABSTRACTObjective:In a previous study, we assembled a multidisciplinary Canadian panel and identified 37 International Classification of Diseases-10-Canada Diagnosis Groups (DGs) for which emergency department (ED) management may potentially reduce mortality (emergency-sensitive conditions). Before using these 37 DGs to calculate a hospital standardized mortality ratio (HSMR) specific to emergency care, we aimed to test their face validity with ED care providers. ⋯ We identified 37 emergency-sensitive DGs that had high face validity with emergency physicians and nurses, which will enable the calculation of an ED-HSMR.

ABSTRACTSmall bowel obstruction (SBO) is a common cause of acute abdominal pain presenting to the emergency department (ED). Although the literature is limited, point-of-care ultrasonography (POCUS) has been found to have superior diagnostic accuracy for SBO compared to plain radiography; however, it is rarely used in North America for this. ⋯ The application of POCUS for SBO is easily learned and applied in the ED. POCUS for SBO may obviate the need for plain radiography and expedite patient care.

ABSTRACTObjective:Despite growing adoption, the impact of prehospital initiation of therapeutic hypothermia on outcomes of cardiac arrest patients is unknown. The objective of this study was to determine if prehospital administration of cold intravenous fluids improved the time-to-target temperature. ⋯ Out-of-hospital cardiac arrest patients treated with prehospital cooling before arrival at our urban hospital did not have faster time-to-target temperature or improvement in outcomes compared to patients cooled immediately on emergency department arrival. Further research is needed to determine if any benefits exist from prehospital cooling prior to its widespread adoption.
