Abstract

The purpose of this study was to determine whether the addition of rapid-acting insulin bolus for enteral feed coverage and a reduction in basal insulin improve glycemic control and decrease hypoglycemia in a medical intensive care unit. A quasi-experimental posttest design assessing glucose control postimplementation of a revised nurse-driven ICU hyperglycemia protocol was conducted on a 16-bed medical intensive care unit at a multicenter hospital system. A daily report of all patients on the ICU hyperglycemia protocol was automated for the inpatient diabetes management team, and pertinent data were collected. Univariate statistics were conducted for all variables. The variability in blood glucose based on different clinical variables was compared using t tests. The hypoglycemic rate was only 0.72%, and no glucose value was less than 40 mg/dL. In addition, the mean glucose value throughout the study was 160.9 +/- 35.6 mg/dL. Findings from this study will hopefully provide insight on an effective way to control glucose within a medical intensive care unit as well as reduce hypoglycemia rates within this setting.
