The Effect of a Liberal Approach to Glucose Control in Critically Ill Patients with Type 2 Diabetes: A Multicenter,...

Area of Science:

• Critical Care Medicine
• Endocrinology
• Clinical Trials

Background:

• Blood glucose control is crucial for critically ill patients, but optimal targets for those with type 2 diabetes remain unclear.
• Previous studies have yielded conflicting results regarding the benefits of intensive versus conventional glucose management.

Purpose of the Study:

• To assess the impact of a "liberal" blood glucose management strategy on hypoglycemia and clinical outcomes in ICU patients with type 2 diabetes.
• To compare a liberal target range (180-252 mg/dl) with a conventional target range (108-180 mg/dl) for intravenous insulin therapy.

Main Methods:

• A multicenter, randomized clinical trial involving 419 adult patients with type 2 diabetes requiring ICU admission for at least three days.
• Patients were assigned to either a liberal or conventional insulin therapy group, with primary outcome of incident hypoglycemia (<72 mg/dl).
• Secondary outcomes included glucose variability, mean glucose levels, and 90-day mortality.

Main Results:

• The liberal glucose target group experienced significantly less hypoglycemia (5% vs. 18%; incident rate ratio, 0.21; P < 0.001).
• The intervention group showed reduced glucose variability and less relative hypoglycemia.
• No significant difference in 90-day mortality was observed between the liberal (29.5%) and conventional (24.9%) groups (P = 0.29).

Conclusions:

• A liberal approach to blood glucose targets in critically ill patients with type 2 diabetes effectively reduces hypoglycemia.
• This strategy did not lead to improvements in patient-centered outcomes, including mortality.
• Further research may be needed to determine the ideal glucose management for this patient population.
