BACKGROUND Population-based data for pediatric cardiac arrest are scant and largely from urban areas. The Resuscitation Outcomes Consortium (ROC) Epistry-Cardiac Arrest is a population-based emergency medical services registry of out-of-hospital nontraumatic cardiac arrest (OHCA). This study examined age-stratified incidence and outcomes of pediatric OHCA.(More)
BACKGROUND There is controversy about which children with minor head injury need to undergo computed tomography (CT). We aimed to develop a highly sensitive clinical decision rule for the use of CT in children with minor head injury. METHODS For this multicentre cohort study, we enrolled consecutive children with blunt head trauma presenting with a score(More)
STUDY OBJECTIVE We systematically summarize pediatric out-of-hospital cardiac arrest epidemiology and assess knowledge of effects of specific out-of-hospital interventions. METHODS We conducted a comprehensive review of published articles from 1966 to 2004, available through MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EmBase, and(More)
OBJECTIVES Making an accurate clinical diagnosis in the field can be a great challenge with pediatric out-of-hospital cardiac arrest (OHCA). We aimed to compare the etiology of pediatric OHCA by pre-hospital clinical diagnosis with etiology by coroner's diagnosis and autopsy. DESIGN As part of the Ontario Pre-hospital Advanced Life Support (OPALS) study,(More)
BACKGROUND Our aim was to develop and evaluate a multidisciplinary pediatric mock trauma code orientation program for residents on their pediatric hospital rotation. METHODS A before and after evaluation of trauma team residents from various programs was conducted. The 1-hour educational session consisted of a 15-minute mock trauma code, a debriefing and(More)
BACKGROUND The Canadian CT Head Rule was prospectively derived and validated to assist clinicians with diagnostic decision-making regarding the use of computed tomography (CT) in adult patients with minor head injury. A recent intervention trial failed to demonstrate a decrease in the rate of head CTs following implementation of the rule in Canadian(More)
Children commonly require sedation and analgesia for procedures in the emergency department. Establishing accurate adverse event and complications rates from the available literature has been difficult because of the difficulty in aggregating results from previous studies that have used varied terminology to describe the same adverse events and outcomes.(More)
STUDY OBJECTIVE To determine the effectiveness of life support courses for health care providers on the basis of one of three outcomes: (1) patient mortality and morbidity, (2) retention of knowledge or skills, and (3) change in practice behavior. METHODS English-language articles from 1975 to 1992 were identified through MEDLINE and ERIC searches,(More)
BACKGROUND Early recognition and treatment are important factors that can help improve survival following necrotizing fasciitis. However, early recognition is complicated by the difficulty in distinguishing the infection from other, less serious soft-tissue infections such as cellulitis. We reviewed the charts of children presenting with necrotizing(More)
CONTEXT The effectiveness of glucocorticoids for patients with croup is well established but it remains uncertain which glucocorticoid regimen is most effective. OBJECTIVE To determine the effectiveness of 3 glucocorticoid regimens in patients with croup. DESIGN Randomized controlled trial with parallel design. SETTING Emergency departments of 2(More)
