Comparison of pediatric poisoning patterns before and during the COVID-19 pandemic in South Korea

The previous studies suggested a decrease in the total number of patients with poisoning but an increase in intentional poisoning cases during the COVID-19 pandemic. By using similar methods to those of previous studies, our results also reached the same conclusion. However, the BSTS model, which predicts real-world time series patterns, seasonal effects, and cumulative effects, shows no significant change in pediatric poisoning patterns during the COVID-19 pandemic.
