A Nationwide Study on Emergency Department Utilization among Pediatric Patients in Korea: A Special Focus on Pediatric Emergency Medical Centers

ABSTRACT

Objective@#Despite Korea’s low birth rate, pediatric emergency medical centers (PEMCs) are grappling with overcrowding. This study evaluates the use of PEMCs in Korea amid a declining birth rate and increased overcrowding. @*Methods@#Data from 176 emergency medical centers (EMCs, 2018–2021) was analyzed using the National Emergency Department Information System, focusing on demographics, Korean Triage and Acuity Scale (KTAS) scores, and pediatric patient outcomes. The most common complaints and diagnoses were identified by the EMC level. This study also examined the characteristics of patients visiting PEMCs. @*Results@#There was a 48% drop in pediatric visits to EMCs during the coronavirus disease 2019 (COVID-19) pandemic. The majority of patients were boys aged 1–4, primarily visiting in the evenings and weekends. The breakdown of cases included 66% disease-related and 34% injury-related. Notably, 8.5% of these visits were via ambulance, 36% were high-acuity according to KTAS, 88% resulted in discharge, and 11% in hospitalization. The median stay was 85 minutes, with 83% utilizing local emergency services. Fever, abdominal pain, and vomiting were the most common complaints, comprising 40% of all visits. @*Conclusion@#Despite a decrease in birth rates, PEMC usage in Korea saw an initial rise followed by a significant decrease during the COVID-19 pandemic. Children aged 1–4 were the most frequent users. The majority of cases were medical rather than trauma-related, and resulted in patient discharge. Strategic redirection of non-urgent cases may help alleviate overcrowding in emergency departments.
