Diabetes Care, 2002 First fully described in 1983, intensive insulin therapy attempts to match the levels of insulin in the blood with the physiologic needs of the diabetic patient (1). The results of the Diabetes Control and Complications Trial solidified the importance of this approach to the prevention of microvascular complications of diabetes (2).
