Effects of Computerized Decision Support Systems On Blood Glucose Regulation in Critically Ill Surgical PatientsCase Study
The use of computerized decision support systems (CDSS) in glucose control for critically ill surgical patients has been reported in both diabetic and nondiabetic patients. Prospective studies evaluating its effect on glucose control are, however, lacking. The objective of this study was to evaluate patient-specific computerized IV insulin dosing on blood glucose levels (BGLs) by comparing patients treated pre-CDSS with those treated post-CDSS.
Patients whose BGLs were managed using CDSS were statistically significantly more likely to have a glucose reading under control (<150 mg/dL) than in the 6-month historical controls and to avoid serious hypoglycemia (p < 0.0001).
Using CDSS Improves Glucose Control
Improved Percentage of Hyperglycemic Events
Blood glucose levels of >150 mg/dL decreased by 50%.
Avoid Hypoglycemic Events
Severe hypoglycemia (defined as BGL <40 mg/dL) decreased from 1% to 0.05%.
Decrease in Total Number of BG Checks
Total number of blood glucose checks decreased an average of 46%.
