Diabetic ketoacidosis at presentation of type 1 diabetes in children in Canada during the COVID-19 pandemic

Sellers, Elizabeth A C; Pacaud, Danièle

Type 1 diabetes is a common chronic illness in childhood. Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes. Early recognition of symptoms of diabetes and immediate initiation of treatment are important factors in preventing DKA at first presentation. We describe the numbers of children presenting with DKA at initial diagnosis across eight Canadian paediatric centres during the COVID-19 pandemic (March 15, 2020 to July 31, 2020) and compare this to the same time period in 2019. Comparing the pre-COVID to the COVID-19 time period, presentation in DKA increased from 36.4% to 55.0% (P<0.0001) and presentation in severe DKA from 37.0% to 48.3% (P=0.044). These findings are concerning and emphasize the importance of awareness of the signs and symptoms of diabetes. In addition, these findings raise concern about access to appropriate and timely care during the COVID-19 pandemic.
