OBJECTIVES: Triage is an essential emergency department (ED) process designed to provide timely management depending on acuity and severity; however, the process may be inconsistent with clinical and hospitalization outcomes. Therefore, studies have attempted to augment this process with machine learning models, showing advantages in predicting critical conditions and hospitalization outcomes. The aim of this study was to utilize nationwide registry data to develop a machine learning-based class

Dog-bite injuries are increasing in Korea, especially in teenagers and adults. A relative's or neighbour's dog may be more dangerous than a stranger's dog. Preventive strategies are needed to prevent dog-bite injuries in adults and children.

We assessed the feasibility and potential efficacy of a virtual reality (VR) environment using a dome screen as a distraction method in young children during intravenous (IV) placement in the pediatric emergency department. This randomized controlled pilot study enrolled children aged 2 to 6 years who underwent IV placement into either the intervention group or the control group. Children in the intervention group experienced VR using a dome screen during IV placement. The child's pain intensity

Importance: Distraction using virtual reality (VR) has been found to provide a clinically significant reduction in the experience of pain during various painful procedures. Commercially available VR systems usually require the user to wear a head-mounted display helmet, which can be challenging for young children, and whether VR can reduce pain during intravenous (IV) placement in young children is currently unknown. Objective: To determine whether a VR environment using a novel domed ceiling sc

BACKGROUND: Successful intravenous catheter placement plays a vital role in the pediatric emergency department. We assessed pediatric emergency department-related factors associated with difficult intravenous catheter placement. METHOD: We retrospectively reviewed the electronic medical records of patients younger than 18 years who had an intravenous catheter placement attempt during their pediatric emergency department stay. Difficult intravenous access was defined as intravenous catheter place

Decision making process is an important component of information use by animals and has already been studied in natural situations. Decision making takes time, which is expressed as a cost in evolutionary explanations of decision making abilities of animals. However, the duration of information assessment and decision making process has not been measured in a natural situation. Here, we use responses of wild magpies (Pica pica) to predictably approaching humans to demonstrate that, regardless of

Intussusception is one of the most common causes of intestinal obstruction in young children. We report a retrospective, observational study of the epidemiology of intussusception in South Korea using the National Health Insurance Service-National Sample Cohort (NHIS-NSC). A cohort of newborns born between 2002 and 2008 was selected. The primary objective was to assess the incidence of intussusception in the pediatric population of Korea. The secondary objectives were to describe the basic epide

BACKGROUND: Abdominal pain, which is a common cause of children presenting to the paediatric emergency department (PED), is often evaluated by ultrasonography (US). However, uncertainty in US reports may necessitate additional imaging. OBJECTIVE: In this study, we evaluated factors contributing to uncertainty in paediatric abdominal US reports in the PED. MATERIALS AND METHODS: This retrospective cohort study included children younger than 18 years of age who underwent abdominal US in the PED of

Purpose: The increasing use of electric personal mobility devices (ePMDs) has been accompanied by an increasing incidence of associated accidents. This study aimed to investigate the characteristics of ePMD-related injuries and their associated factors. Methods: This cross-sectional study was conducted using data from the Emergency Department-based Injury In-depth Surveillance database from 2014 to 2018. All patients who were injured while operating an ePMD were eligible. The primary outcome was

<b>Objective:</b> We developed a novel compression assist device (palm presser) to perform chest compressions using a palm in infant cardiopulmonary resuscitation (CPR). We hypothesized that the palm presser will increase compression depth without increasing hands-off time and will reduce rescuer fatigue compared with the two-finger technique (TFT).<b>Methods:</b> In this randomized crossover manikin trial, participants performed two minutes of CPR with a 30:2 compression:ventilation ratio using

BACKGROUND: Intravenous (IV) placement is a common procedure experienced by children visiting the pediatric emergency department (PED). However, uncontrolled anxiety and pain cause children to interfere with the procedure. In this pilot study, we sought to evaluate the effectiveness of tablet personal computers as a distraction method during IV placement. METHODS: This is a single-center pilot study conducted at a tertiary teaching hospital. Children visiting the PED were eligible if they were a

OBJECTIVES: The objective of this study was to define the care factors that are important to caregivers' satisfaction with pediatric laceration repair and the overall emergency department (ED) experience. METHODS: This was a cross-sectional observation study performed in an urban tertiary hospital. The caregivers of patients younger than 18 years who presented to the ED for laceration repair completed a survey. Demographic data were analyzed. Univariate and multivariate logistic regressions were

N-terminal pro-brain natriuretic peptide (NT-proBNP) has been studied as a diagnostic screening tool for Kawasaki disease (KD). However, brain natriuretic peptide (BNP) has been less studied while has less variability among age groups. We aimed to find out if BNP can be used as a diagnostic screening tool for KD in Korea. This was a retrospective cohort study performed in a single pediatric emergency department. Patients younger than 19 years of age who presented with fever and underwent BNP exa
