Abstract

Intravenous (IV) insulin infusion is the standard of care for treating diabetic ketoacidosis (DKA) worldwide. Subcutaneous (SC) insulin aspart could decrease the use of health care resources. To compare the cost-effectiveness of mild uncomplicated DKA management with SC insulin aspart vs IV insulin infusion among pediatric patients from the perspective of a public health care payer using clinical data. This economic evaluation included children aged 2 to 14 years presenting to the emergency department of a single academic medical center with mild DKA between January 1, 2015, and March 15, 2020. The medical records for DKA treatment course and its associated hospitalization costs were reviewed. Data were analyzed from January 1, 2015, to March 15, 2020. Subcutaneous insulin aspart vs IV regular insulin infusion. The incremental cost-effectiveness ratio (US dollars per hour), duration of DKA treatment, and length of hospital stay. A total of 129 children with mild DKA episodes (mean [SD] age, 9.9 [3.1] years; 72 girls [55.8%]) were enrolled in the study. Seventy children received SC insulin aspart and 59 received IV regular insulin. Overall, the length of hospital stay in the SC insulin group was reduced (mean, 16.9 [95% CI, -31.0 to -2.9] hours) compared with the IV insulin group (P = .005). The mean (SD) cost of hospitalization in the SC insulin group (US $1071.99 [US $523.89]) was less than that in the IV insulin group (US $1648.90 [US $788.03]; P = .001). The incremental cost-effectiveness ratio was -34.08 (95% CI, -25.97 to -129.82) USD/h. The use of SC insulin aspart was associated with a lower likelihood of prolonged hospital stay (β = -17.22 [95% CI, -32.41 to -2.04]; P = .03) than IV regular insulin when controlling for age and sex. Findings of this economic evaluation suggest that SC insulin aspart is dominant vs IV regular insulin in the management of mild uncomplicated DKA in children.
