Objective

This retrospective study examines the effect of goal range on incidence of hypoglycemia in patients receiving intravenous insulin therapy (managed with EndoTool).

Setting

Cohort of five unaffiliated acute care hospitals.

Results

• Incidence of hypoglycemia <70 mg/dL was 35.5% lower with a goal range of 160-200 mg/dL goal range than a goal range of 100-140 mg/dL (0.22% vs 0.34% of blood glucose readings).
• Whereas 73% of hypoglycemia events occurred following a blood glucose <120 mg/dL, 27% occurred following a blood glucose >120 mg/dL.

Conclusions

With use of EndoTool to manage intravenous insulin therapy, incidence of hypoglycemia may likely decrease by reducing the overall goal range spread concurrent to reducing the upper limit.
