Critically ill patients who require intensive care for more than five days carry 20% risk of death and significant morbidity. Hyperglycemia and insulin resistance are common in critical care settings, even observed in those without preexisting diabetes.

Newly detected hyperglycemia (admission or fasting blood glucose >126 mg/dl or two random blood glucose >200 mg/dl) in one study [1] was associated with higher in-hospital mortality (16%) than established diabetes (3%) or normal blood glucose (1.7%).The risk of in-hospital complications and ICU death increase by 3% for each 20 mg/dl increase in blood glucose above 100 mg/dl.
