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.

Study Objective: Our primary objectives were to identify clinical practice guideline recommendations for children with acute mild traumatic brain injury (mTBI) presenting to an emergency department (ED), appraise their overall quality, and synthesize the quality of evidence and the strength of included recommendations.

Methods: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and medical association websites from January 2012 to May 2023 for clinical practice guidelines with at least 1 recommendation targeting pediatric mTBI populations presenting to the ED within 48 hours of injury for any diagnostic or therapeutic intervention in the acute phase of care (ED and inhospital). Pairs of reviewers independently assessed overall clinical practice guideline quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool.

Traumatic brain injury (TBI) is the leading cause of death and disability in children. Many clinical practice guidelines (CPGs) have addressed pediatric TBI in the last decade but significant variability in the use of these guidelines persists. Here, we systematically review CPGs recommendations for pediatric moderate-to-severe TBI, evaluate the quality of CPGs, synthesize the quality of evidence and strength of included recommendations, and identify knowledge gaps.

Article Synopsis
  • Children with congenital heart disease (CHD) often face rapid health decline during common illnesses, making effective treatment in emergency departments (ED) critical for their survival.
  • Previous research indicates that ED physicians may feel unprepared to handle CHD cases due to a lack of guidance, prompting the development of a Clinical Decision Support System (CDSS) aimed at aiding their decision-making process.
  • A pilot study showed that using the CDSS significantly improved physicians' focus on CHD-specific decisions compared to standard care, highlighting its potential to enhance clinical management and communication among healthcare providers.

Background And Objectives: Children with congenital heart disease (CHD), have fragile hemodynamics and can deteriorate due to common childhood illnesses and the natural progression of their disease. During these acute periods of deterioration, these children often present to their local emergency departments (ED) where expertise in CHD is limited, and appropriate intervention is crucial to their survival. Previous studies identified that determining the appropriate intervention for CHD patients can be difficult for ED physicians, particularly since key components of effective decision making are not being met.

Article Synopsis
  • Children with congenital heart disease (CHD) face unique challenges during emergency situations, as symptoms can resemble common childhood illnesses, potentially leading to misdiagnosis or delayed treatment by emergency department (ED) physicians.
  • CHD experts and ED physicians exhibit different cognitive processes in diagnosing and treating CHD patients, with experts quickly identifying cardiac issues while ED physicians tend to take longer to connect non-specific symptoms to CHD.
  • The study's findings highlight the need for a web-based decision support tool to assist ED physicians in better recognizing and managing cases of CHD.
