The Effect of COVID-19 Stay-At-Home Orders on the Rate of Pediatric Foreign Body Ingestions.

Background: Foreign body ingestions are a common presentation in the emergency department (ED), particularly in young children.
Objective: We sought to determine whether the COVID-19 pandemic lockdowns had an effect on the proportion of foreign body ingestions.
Methods: We performed a retrospective review of the Pediatric Health Information System for patients younger than 19 years who were identified by International Classification of Diseases, Tenth Revision codes for foreign body ingestion. We analyzed patients in the following three groups: young children (younger than 5 years), school-aged children (5-12 years), and adolescents (13 years and older), using an interrupted time series analysis. Our primary outcome was the difference in proportion of foreign body ingestions. We compared 1 year after the declaration of the COVID-19 pandemic (March 13, 2020 to March 31, 2021) with the previous 3 years (March 1, 2017 to March 12, 2020).
Results: Total pediatric ED encounters decreased in the post period (p < 0.01); 4902 patients per year presented for foreign body ingestion pre-COVID-19 shutdown vs. 5235 patients per year post-COVID-19 shutdown. In all three age groups (young children, school-age children, and adolescents), there was a higher proportion of foreign body ingestions post-COVID-19 shutdown (p < 0.01, p < 0.01, and p = 0.028, respectively), driven primarily by the decrease in total ED encounters. In the youngest age group (younger than 5 years), there was also a significant increase in slope for foreign body ingestions post-COVID-19 (p = 0.010).
Conclusions: The proportion of foreign body ingestions increased after the declaration of the COVID-19 pandemic, primarily driven by an overall decrease in total ED volume.
