Objective: The aim of the study was to evaluate the impact of an insulin infusion calculator incorporated into electronic health record system in reducing the rate of hypoglycemia in diabetic ketoacidosis (DKA) management.
Methods: Retrospective chart review of patients with primary admission diagnosis of DKA was conducted in a university-affiliated academic medical center. End points including the rate of hypoglycemia, time to DKA resolution, rate of hypokalemia, time on insulin drip, and length of stay were measure before and after implementation of DKA calculator.
Results: Of 181 adult patients admitted for primary diagnosis of DKA, 103 were managed using the calculator. After implementation of the calculator, incidence of hypoglycemia and severe hypoglycemia were significantly reduced by 70% and 87%, respectively (P < 0.01). No difference was observed for time to DKA resolution, time on insulin drip, and length of stay.
Conclusions: Implementation of DKA insulin infusion calculator significantly reduced the rate of hypoglycemia. Future improvements should focus on reducing time to DKA resolution and length of stay.
