Sweet victory: Optimizing glycemic control after coronary artery bypass grafting

Poor glycemic control, regardless of patients' diabetic status, is associated with worse outcomes after coronary artery bypass grafting. As a result, in the perioperative and postoperative setting, the use of insulin is recommended to maintain glucose levels below 180 mg/dl (10.0 mmol/L). However, challenges exist and errors may occur that can prohibit adequate glucose management. In this commentary, we highlight a real-world example of an educational intervention to empower health workers in managing patients' glucose levels after coronary artery bypass grafting in order to improve postoperative outcomes. We discuss the current evidence and guidelines on peri- and postoperative glycemic control for patients undergoing cardiac surgery and present further quality improvement opportunities that may be introduced.
