ABSTRACT
OBJECTIVES: This study aimed to investigate the patterns of pediatric patients visiting emergency departments (EDs) before and after the COVID-19 pandemic and evaluate the interactive effect between the COVID-19 outbreak and age groups. METHODS: We performed a cross-sectional study using the nationwide emergency patient database in Korea from January 2019 to December 2020. Pediatric patients (≤18 years) who visited all 402 nationwide EDs were included. The age- and sex-standardized incidence rates of pediatric ED visits per 1,000,000 person-days were calculated, and the incidence rate ratio (IRR) was calculated. The adjusted odds ratio (aOR) and 95% confidence interval (CI) of in-hospital mortality were calculated by a multivariable logistic regression. RESULTS: Among 2,808,756 patients, 1,835,045 (65.3%) patients visited before COVID-19, and 973,711 (34.7%) patients visited after the COVID-19 period. The standardized incidence rates of ED visits per 1,000,000 person-days were 589.3 in the before COVID-19 group and 326.9 in the after COVID-19 group (IRR (95% CI): 0.55 (0.53-0.58)). By diagnosis, the IRRs (95% CI) of mental health disorders (0.84 (0.42-1.65)) and self-harm or suicidal attempts (0.99 (0.38-2.59) were not significant, while the incidence rate of infectious disease was significantly decreased (0.48 (0.42-0.54)). The aOR (95% CI) of in-hospital mortality after COVID-19 was 1.58 (1.44-1.73) compared to that before COVID-19. CONCLUSIONS: During the COVID-19 pandemic, the incidence of pediatric ED visits decreased, and these effects differed by age group. Age-specific policies are needed to ensure that children receive the care they need at the right time.

PURPOSE: Considering the risk of coronavirus disease (COVID-19) transmission through infected droplets, emergency department (ED) operations in response to febrile patients should be planned. We investigated the general and clinical characteristics of febrile patients visiting the ED and changes in admission rates via the ED during the COVID-19 outbreak. MATERIALS AND METHODS: We performed a retrospective analysis of prospectively collected patients who visited 402 EDs in the Republic of Korea with febrile symptoms between January 27 and May 31, 2020 and compared them to those enrolled before the COVID-19 outbreak. The primary outcome was admission rate; the secondary outcome was length of stay (LOS) in the ED. RESULTS: In total, 266519 patients had febrile symptoms at ED presentation after the COVID-19 outbreak. In 2019, before the outbreak, there were 437762 patients. The rate of ED visits among pediatric patients (aged <15 years) decreased to 21.4% after the COVID-19 outbreak, compared with 41.8% in 2019. The proportion of patients admitted after ED management was higher after the outbreak (31.3%) than before (25.2%). The adjusted odds ratio for admission was 1.04 (95% confidence interval: 1.02-1.05) after the outbreak. Compared to before the COVID-19 outbreak, the median ED LOS increased by 16 min after the outbreak. CONCLUSION: This study confirmed that admission rates and ED LOS increased for febrile patients visiting the ED after the COVID-19 outbreak. This could provide evidence for developing ED-related strategies in response to the ongoing COVID-19 outbreak and other infectious disease pandemics.

BACKGROUND: The purpose of this study was to review the nationwide emergency care-related health policies during the coronavirus disease 2019 (COVID-19) pandemic disaster in Korea and to analyze the effects of the policies on the safety of patients who visit emergency departments (EDs) during this period. METHODS: This study is a quasi-experiment study. The study population was patients who visited all 402 EDs in Korea between December 31, 2019 and May 13, 2020, using the National Emergency Department Information System (NEDIS) database. The study period was classified into 5 phases according to the level of national crisis warning of infectious disease and the implementation of emergency care-related health policies, and all study phases were 27 days. The primary outcome was in-hospital mortality, and the secondary outcome was length of stay (LOS) in the ED during the COVID-19 outbreak. RESULTS: The number of ED visits during the study period was 2,636,341, and the in-hospital mortality rate was 1.4%. The number of ED visits decreased from 803,160 in phase 1 to 496,619 in phase 5 during the study period. For in-hospital mortality, the adjusted odds ratio (OR) (95% confidence interval) was 0.77 (0.74-0.79) in phase 5 compared to phase 3. Additionally, by subgroup, the ORs were 0.69 (0.57-0.83) for the patients with acute myocardial infarction and 0.76 (0.67-0.87) for severe trauma in phase 5 compared to phase 3. The ED LOS increased while the number of ED visits decreased as the COVID-19 pandemic progressed, and the ED LOS declined after policy implementation (beta coefficient: -5.3 [-6.5 to -4.2] minutes in phase 5 compared to phase 3). CONCLUSION: Implementing appropriate emergency care policies in the COVID-19 pandemic would have contributed to improving the safety of all emergency patients and reducing in-hospital mortality by preventing excessive deaths.
