Study Hypothesis: Use of opioids for treatment of headache in the emergency department (ED) is associated with an increased 1-year risk of opioid-related adverse events.

Objective: To assess the safety and efficacy of opioid prescribing for ED patients with headache.

Methods: We performed a multicenter observational cohort study using linked administrative data.

Background: The presence of an intraluminal thrombus in acutely symptomatic carotid stenosis is thought to represent a high-risk lesion for short-term stroke reccurrence though evidence on natural history and treatment is lacking, leading to equipoise and much variation in practice. The objective of this study was to map these variations in practice (medical management and timing of revascularization), determine the considerations that influence clinician decision-making in this condition and gather opinions that inform the development and design of future trials in the area.

Methods: This was a mixed-methods study using both quantitative survey methods and qualitative interview-based methods.

Background: Disparities in health outcomes, including increased chronic disease prevalence and decreased life expectancy for Indigenous people, have been shown across settings affected by white settler colonialism including Canada, the United States, Australia, and New Zealand. Emergency departments (EDs) represent a unique setting in which urgent patient need and provider strain interact to amplify inequities within society. The aim of this scoping review was to map the ED-based interventions aimed at improving equity in care for Indigenous patients in EDs.

Background: Our previous research showed that, in Alberta, Canada, a higher proportion of visits to emergency departments and urgent care centres by First Nations patients ended in the patient leaving without being seen or against medical advice, compared with visits by non-First Nations patients. We sought to analyze whether these differences persisted after controlling for patient demographic and visit characteristics, and to explore reasons for leaving care.

Methods: We conducted a mixed-methods study, including a population-based retrospective cohort study for the period of April 2012 to March 2017 using provincial administrative data.

Introduction: Emergency airway management is a common and critical task EMS clinicians perform in the prehospital setting. A new set of evidence-based guidelines (EBG) was developed to assist in prehospital airway management decision-making. We aim to describe the methods used to develop these EBGs.

Article Synopsis
  • Plant exposures can cause serious toxicity, often seen in emergency situations, with some plants leading to life-threatening conditions like cardiovascular failure.
  • A case study is detailed where a 65-year-old patient developed a severe heart condition after mistakenly ingesting a toxic plant containing aconitine, despite extensive treatment efforts.
  • The patient was successfully treated with extracorporeal membrane oxygenation (ECMO) therapy, leading to recovery, which emphasizes the importance of proper plant identification and available management strategies for such toxicities.
