Guardian of Glucose, Consider Using an Electronic Algorithm to Achieve Postcardiac Surgery Glycemic Control


This prospective study compares post-operative glycemic control for cardiac surgery patients before and after implementation of a software-based tool for insulin dosing (EndoTool).


800-bed hospital, Level II trauma center and regional referral center for tertiary and quaternary care.

  • Time to control in the cardiovascular recovery unit decreased 78% with EndoTool, from 9 hours to just over 2 hours.
  • Percentage of CABG patients who achieved the optimal blood glucose range of 71-150 mg/dL in the cardiovascular intensive care unit more than quadrupled with EndoTool, from 17% to 91.5%.
  • Mean average incidence of hypoglycemia <70 mg/dL decreased 84% with EndoTool, from 3% to 0.48% of blood glucose measurements.

There is overwhelming evidence that a software-based tool for insulin dosing (EndoTool) improves glycemic control for cardiac surgery patients; additional benefits include projected cost savings from decreased length of stay and mortality as well as overall simplicity of use, ability to customize based on service line/patient population, and user support.
