Insights
Pediatric emergency department visits dropped 55.5% post-COVID-19, with fewer infants and young children but more adolescents. Illness patterns shifted, with more non-specific symptoms and trauma visits.
Area of Science:
- Pediatric Emergency Medicine
- Public Health
- Epidemiology
Background:
- The COVID-19 pandemic significantly altered healthcare utilization patterns globally.
- Understanding shifts in pediatric emergency department (ED) use is crucial for resource allocation and public health planning.
- Pre-existing trends in pediatric ED visits may have been exacerbated or modified by pandemic-related changes.
Purpose of the Study:
- To investigate changes in pediatric ED utilization before and after the COVID-19 pandemic.
- To analyze age-specific trends, triage severity, diagnostic categories, and clinical presentations in pediatric ED visits.
- To inform age-specific strategies for emergency planning and pediatric public health policy.
Main Methods:
- Retrospective analysis of 71,560 pediatric ED visits (Samsung Changwon Hospital, 2016-2023).
- Categorization into pre-COVID-19 (2016-2019) and post-COVID-19 (2020-2023) periods.
- Analysis of age groups, Korean Triage and Acuity Scale (KTAS) scores, diagnoses (ICD-10), and outcomes.
Main Results:
- A 55.5% decrease in overall pediatric ED visits post-pandemic.
- Shift in age distribution: decreased visits for infants/young children, increased visits for adolescents.
- Increased lower-acuity visits (KTAS 4), higher discharge rates, reduced admissions, and a rise in non-specific symptoms and trauma diagnoses.
Conclusions:
- The COVID-19 pandemic has profoundly impacted pediatric ED utilization, altering visit volume, illness patterns, and severity by age.
- Significant changes observed in diagnostic categories, with a decrease in respiratory/infectious diseases and an increase in non-specific symptoms and trauma.
- Findings necessitate age-specific emergency planning and public health policies to address pandemic-induced behavioral and healthcare access changes.
Abstract:
Purpose: This study investigates trends in pediatric emergency department (ED) utilization before and after the COVID-19 pandemic, with a focus on age-specific patterns, triage severity, diagnostic categories, and clinical presentations. Methods: Data were collected for 71,560 individuals (40,428 males and 31,132 females aged 0-18 years) who visited the ED at Samsung Changwon Hospital between 1 January 2016 and 31 December 2023. Patients were categorized into pre-COVID-19 (2016-2019) and post-COVID-19 (2020-2023) periods. Age, Korean Triage and Acuity Scale (KTAS) scores, visit outcomes, diagnostic codes (ICD-10), and vital signs were analyzed. Age-specific analyses were performed in four groups: <12 months, 1-6 years, 7-12 years, and 13-18 years. Results: Since the COVID-19 pandemic, pediatric ED visits have decreased by 55.5%. The proportion of visits by infants (<12 months) and young children (1-6 years) decreased, and adolescent visits increased. Post-pandemic, there was a significant increase in lower-acuity visits (KTAS 4) and discharge rates, alongside a reduction in admissions. Visits for respiratory and infectious diseases (ICD-10 J and A & B codes) decreased markedly, and visits for non-specific symptoms (R codes) and trauma (S & T codes) increased. The mean body weight of young children increased significantly after the COVID-19 period. Conclusions: The COVID-19 pandemic has had a profound and lasting effect on pediatric emergency department utilization, with changes in the number of visits, illness patterns, and severity by age group. These findings highlight the need for age-specific strategies in emergency planning and pediatric public health policy, particularly in managing the indirect effects of pandemic-induced changes in behavior and access to healthcare.
