Objective: To describe the quality of glycemic control in patients in intensive care units (ICUs) treated with an intravenous (IV) insulin infusion at a teaching hospital.
Method: This retrospective study included patients admitted to the ICU and treated with an IV insulin infusion for at least 12 h between August 1 and November 30, 2011. Medical charts were reviewed. The primary quality indicator for glycemic control was the mean percent of blood glucose values per patient in the 6.1 to 8 mmol/L target range.
Results: A total of 351 patients were included; 61.5% of subjects had no known diabetes. Admissions were mainly for surgery (61.3%). The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 16.8 +/- 7.3. The mean percent of blood glucose values per patient in the 6.1 to 8 mmol/L range was 35% for all subjects and 26.2% for patients with diabetes. If a target of 6.1 to 10 mmol/L was considered, those values became 63% and 54.6%. At least 1 episode of hyperglycemia (> 10 mmol/L), hypoglycemia (< 4 mmol/L) or severe hypoglycemia (< 2.2 mmol/L) was documented in 68%, 9% and 1% of subjects, respectively. Glycemic variability (SD) was 1.9 mmol/L, and the median hyperglycemic index was 0.77 (interquartile [IQ]: 0.24 to 1.63).
Conclusion: The quality of glycemic control in patients in the ICU at our hospital needs to be improved. A new computerized IV insulin protocol is currently being tested.
