At 12 months the mortality was with the intensive insulin regimen compared with in the control group. The benefit was most apparent in patients with greater than 5 days of stay in the intensive care unit. Tight and early glycemic control was associated with the more rapid improvement of insulin Intensive insulin therapy was associated with reduced bloodstream infections by 46 acute renal failure by 41 and critical illness polyneuropathy by 44 . Using multivariate analysis the authors suggested that improved metabolic control as reflected by normoglycemia rather than the infused insulin dose per se was responsible for the beneficial effects of intensive insulin therapy. However achieving normoglycemia and the administration of insulin are linked and from the available evidence it appears likely that both factors played a key role in the improved outcome. The outcome data from the Leuven Intensive Insulin Therapy Trial indicates that there is a direct relationship between the degree of glycemic control and hospital In the long-stay patients 5 days in the ICU the cumulative hospital mortality was 15 in patients with a mean blood glucose less than 110 mg dL 25 in those with a blood glucose between
