Improved perioperative glycemic control by continuous insulin infusion under supervision of an endocrinologist does not increase costs in patients with diabetes.

Objective: To evaluate whether glycemic control can be improved perioperatively by implementing an insulin infusion protocol for patients with diabetes undergoing coronary artery bypass graft (CABG) surgery, without creating an additional financial burden. We also evaluated impact of such a protocol on hospital length of stay (LOS) and development of deep sternal wound infections (DSWI).

Methods: We developed an insulin infusion glycemic control protocol (IGCP) under supervision and consultation of an endocrinologist.
