To optimize the identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected children, specimen collection and testing method are crucial considerations. Ideally, specimen collection is easy and causes minimal discomfort, and the laboratory approach is simple, accurate, and rapid. In this prospective cohort study we evaluated the accuracy of a point-of care nucleic acid device using caregiver/patient self-collected buccal swabs.

Article Synopsis
  • The study aimed to evaluate the relationship between social behaviors and SARS-CoV-2 test positivity in children under 18 years old during 2020-2022, using data from emergency departments.
  • It found that attending social gatherings increased the chances of testing positive for SARS-CoV-2 in children aged 5-<12 years while in-person daycare/school attendance was linked to a lower risk of positivity across all age groups.
  • Key findings indicated that children's risk of infection was influenced by factors like mask-wearing and exposure to infected contacts, with settings like schools promoting better public health practices, thus lowering risk.

Article Synopsis
  • A multicenter study in Canada compared symptoms and outcomes in children with different SARS-CoV-2 variants, focusing on data from 7272 pediatric emergency department visits.
  • Of the 1440 children who tested positive for COVID-19, those with the Alpha variant exhibited the fewest core symptoms, while those infected with the Omicron variant had the highest report of symptoms.
  • Findings indicated that the Omicron variant was linked to lower respiratory and systemic symptoms, whereas the Delta variant was notably associated with upper respiratory tract symptoms and fever.

Background: Caregiver hesitancy for their children to receive the COVID-19 vaccine remains due to concerns regarding safety and efficacy, but also due to fear of vaccine administration-related pain and distress. Study objectives were to determine caregivers' perceptions regarding both their personal and child's COVID-19 vaccine administration-related stress and fear and relate this to their likelihood to allow their child to receive COVID-19 vaccinations.

Methods: This study was a secondary data analysis of a multicentre, cross-sectional survey of caregivers presenting to four Canadian pediatric emergency departments.

Introduction: Patient engagement in healthcare research is a necessity to ensure that research objectives align with priorities, outcomes and needs of the population under study, and to facilitate ease of implementation and adoption of findings. In clinical trials, there is an increasing focus on patient engagement during the planning and conduct of clinical trials due to the potential for ethical and methodological benefits. As patient engagement in clinical trials increases, there is a need to evaluate the approaches of these activities to contribute evidence on what is most appropriate and successful.

Purpose: The goal of this study was to assess if caregivers' attitudes toward the regulatory process of approving the vaccine against coronavirus disease 2019 (COVID-19) for children aged <12 years changed after a vaccine was approved for adults.

Methods: This was a larger scale COVIPAS (COVID-19 Parental Attitude Study) survey of caregivers presenting with their children aged ≤12 years for emergency care in 12 hospitals in the United States, Canada, and Israel. The study compared willingness to support abridged research into COVID-19 vaccines for children between the peak of the pandemic (March-May 2020) and after a COVID-19 vaccine became available for adults (December 2020-March 2021).

Vaccinating children against COVID-19 is critical as a public health strategy in order to reach herd immunity and prevent illness among children and adults. The aim of the study was to identify correlation between willingness to vaccinate children under 12 years old, and vaccination rate for adult population in Canada, the United States, and Israel. This was a secondary analysis of a cross-sectional survey study (COVID-19 Parental Attitude Study) of parents of children 12 years and younger presenting to 12 pediatric emergency departments (EDs).

Vaccines against COVID-19 are likely to be approved for children under 12 years in the near future. Understanding vaccine hesitancy in parents is essential for reaching herd immunity. A cross-sectional survey of caregivers in 12 emergency departments (ED) was undertaken in the U.

Objective: To determine if caregivers of children presenting to pediatric emergency departments (EDs) during the COVID-19 pandemic are delaying presenting to care for fear of contracting COVID-19.

Methods: This was a pre-planned secondary analysis of a cross-sectional survey study of caregivers accompanying their children aged 0-19 years to 16 pediatric EDs in 5 countries from May to June 2020. An anonymous online survey, completed by caregivers via RedCAP, included caregiver and child demographics, presenting complaints, if they delayed presentation and whether symptoms worsened during this interval, as well as caregiver concern about the child or caregiver having COVID-19 at the time of ED visit.

Objectives: The aim of this study was to quantify the effect of the COVID-19 pandemic on pediatric emergency department (ED) utilization and outcomes.

Methods: This study is an interrupted-time-series observational study of children presenting to 11 Canadian tertiary-care pediatric EDs. Data were grouped into weeks in 3 study periods: prepandemic (January 1, 2018-January 27, 2020), peripandemic (January 28, 2020-March 10, 2020), and early pandemic (March 11, 2020-April 30, 2020).

The coronavirus disease 2019 (COVID-19) pandemic has taken an unprecedented global toll and vaccination is needed to restore healthy living. Timely inclusion of children in vaccination trials is critical. We surveyed caregivers of children seeking care in 17 Emergency Departments (ED) across 6 countries during the peak of the pandemic to identify factors associated with intent to participate in COVID-19 vaccine trials.

Background: More than 100 COVID-19 vaccine candidates are in development since the SARS-CoV-2 genetic sequence was published in January 2020. The uptake of a COVID-19 vaccine among children will be instrumental in limiting the spread of the disease as herd immunity may require vaccine coverage of up to 80% of the population. Prior history of pandemic vaccine coverage was as low as 40% among children in the United States during the 2009 H1N1 influenza pandemic.

Purpose: This study determined the predictors of caregivers' willingness to accept an accelerated regulatory process for the development of vaccines against coronavirus disease 2019 (COVID-19).

Methods: An international cross-sectional survey was administered to 2557 caregivers of children in 17 pediatric emergency departments (EDs) across 6 countries from March 26, 2020, to June 30, 2020. Caregivers were asked to select 1 of 4 choices with which they most agreed regarding a proposed COVID-19 vaccine-approval process, in addition to questions regarding demographic characteristics, the ED visit, and attitudes about COVID-19.

Objective: Cerebrospinal fluid (CSF) shunt malfunction is one of the most common life-threatening neurosurgical conditions. In the emergency department (ED), imaging techniques to identify shunt malfunction include the shunt series (SS) and CT scanning of the head. We sought to determine the test characteristics of the SS and CT scan for identifying children with shunt malfunction.
