Little is known about the risk factors for, and of, developing post-COVID-19 conditions (PCCs) among children.To estimate proportion of SARS-CoV-2-positive children with PCCs 90 days after a positive test result, to compare this SARS-CoV-2-negative children, assess associated PCCs.This prospective cohort study, conducted in 36 emergency departments (EDs) 8 countries between March 7, 2020, January 20, 2021, included 1884 who completed 90-day follow-up; 1686 these were frequency matched by...
Procedural sedation for children undergoing painful procedures is standard practice in emergency departments worldwide. Previous studies of department are limited by their single-center design and underpowered to identify risk factors serious adverse events (SAEs), thereby limiting influence on patient outcomes.To examine the incidence associated with sedation-related SAEs.This prospective, multicenter, observational cohort study was conducted 6 pediatric Canada between July 10, 2010,...
Objectives The aim of this study was to quantify the effect COVID-19 pandemic on pediatric emergency department (ED) utilization and outcomes. Methods This is an interrupted-time-series observational children presenting 11 Canadian tertiary-care EDs. Data were grouped into weeks in 3 periods: prepandemic (January 1, 2018–January 27, 2020), peripandemic 28, 2020–March 10, early (March 11, 2020–April 30, 2020). These periods compared with same time intervals 2 preceding calendar years. Primary...
<h3>Importance</h3> Severe outcomes among youths with SARS-CoV-2 infections are poorly characterized. <h3>Objective</h3> To estimate the proportion of children severe within 14 days testing positive for in an emergency department (ED). <h3>Design, Setting, and Participants</h3> This prospective cohort study 14-day follow-up enrolled participants between March 2020 June 2021. Participants were aged younger than 18 years who tested infection at one 41 EDs across 10 countries including...
<h3>Importance</h3> It is not clear whether adherence to preprocedural fasting guidelines prevent pulmonary aspiration and associated adverse outcomes during emergency department (ED) sedation of children. <h3>Objective</h3> To examine the association between duration incidence sedation-related in a large sample <h3>Design, Setting, Participants</h3> We conducted planned secondary analysis multicenter prospective cohort study children aged 0 18 years who received procedural for painful...
<h3>BACKGROUND:</h3> Emergency department overcrowding has been associated with increased odds of hospital admission and mortality after discharge from the emergency in predominantly adult cohorts. The objective this study was to evaluate association between crowding several adverse outcomes among children seen at a pediatric department. <h3>METHODS:</h3> We conducted retrospective cohort involving all visiting 8 Canadian departments across 4 provinces 2010 2014. analyzed mean departmental...
Introduction Bronchiolitis exerts a significant burden of illness on infants worldwide. National guidelines advise only supportive care. There is evidence that treating with bronchiolitis combination inhaled epinephrine and dexamethasone may reduce hospital admissions. Objective To determine if treated (delivered by metered dose inhaler spacer or nebulizer) in the emergency department 2-day course oral have fewer hospitalizations compared to placebo. Methods The BIPED study (Bronchiolitis...
Shiga toxin-producing Escherichia coli (STEC) infections are leading causes of pediatric acute renal failure. Identifying hemolytic uremic syndrome (HUS) risk factors is needed to guide care.We conducted a multicenter, historical cohort study identify features associated with development HUS (primary outcome) and need for replacement therapy (RRT) (secondary in STEC-infected children without at initial presentation. Children aged <18 years who submitted STEC-positive specimens between...
As residency programs transition from time- to performance-based competency standards, validated tools are needed measure learning outcomes and studies required characterize the experience for residents. Since pediatric musculoskeletal (MSK) radiograph interpretation can be challenging emergency medicine trainees, we introduced Web-based MSK system with performance endpoints into (PEM) fellowships determined feasibility effectiveness of implementing this intervention.This was a multicenter...
There is a need to understand the long-term outcomes among children infected with SARS-CoV-2.
Objective To describe senior paediatric emergency clinician perspectives on the optimal frequency of and preferred modalities for practising critical procedures. Methods Multicentre multicountry cross-sectional survey clinicians working in 96 EDs affiliated with Pediatric Emergency Research Network. Results 1332/2446 (54%) provided information suggested practice learning 18 Yearly was recommended six procedures (bag valve mask ventilation, cardiopulmonary resuscitation (CPR), endotracheal...
<h3>Background:</h3> Radial-head subluxation is an easily identified and treated injury. We investigated whether triage nurses in the emergency department can safely reduce radial-head at rates that are not substantially lower than those of physicians. <h3>Methods:</h3> performed open, noninferiority, cluster-randomized control trial. Children aged 6 years younger who presented to with a presentation consistent had sustained known injury previous 12 hours were assigned either nurse-initiated...
Abstract Background PECOS is an ongoing study aimed to characterize long-term outcomes following pediatric SARS-CoV-2 infection. Methods This a cross-sectional analysis of infected and uninfected cohorts at baseline. Participants (0–21 years) with laboratory-confirmed infection were enrolled as infected. Uninfected defined individuals without history or laboratory evidence Outcome measures included demographics, medical history, review symptoms, physical exam, cardiopulmonary evaluation...
Despite the high number of children treated in emergency departments, patient safety risks this setting are not well quantified. Our objective was to estimate risk and type adverse events, as their preventability severity, for a paediatric department. prospective, multicentre cohort study enrolled presenting care during one 168 8-hour shifts across nine departments. primary outcome an event within 21 days enrolment which related provided at visit. We identified 'flagged outcomes' (such...
Introduction Procedural sedation and analgesia have become standard practice in paediatric emergency departments worldwide. Although generally regarded as safe, serious adverse events such bradycardia, asystole, pulmonary aspiration, permanent neurological injury death been reported, but their incidence is unknown due to the infrequency of occurrence lack surveillance safety. To improve our understanding safety, comparative effectiveness variation care procedural sedation, we are...
Children rarely experience critical illness, resulting in low exposure of emergency physicians (EPs) to procedures. Our primary objective was describe senior EP confidence, most recent performance, and/or supervision nonairway Secondary objectives were compare responses between those who work exclusively PEM and do not determine whether confidence changed for selected procedures according increasing patient age.Survey EPs working 96 departments (EDs) affiliated with the Pediatric Emergency...
For assessing the skill of visual diagnosis such as radiograph interpretation, competency standards are often developed in an ad hoc method, with a poorly delineated connection to target clinical population.Commonly used methods assess for interpretation subjective and potentially biased due small sample size cases, evaluations, or include expert-generated case-mix versus representative from field. Further, while digital platforms available against objective standard, they have not adopted...
