The relationship between diabetes and surgical site infection following coronary artery bypass graft surgery in current-era models of care

Abstract

Background: Although diabetes is a recognized risk factor for postoperative infections, the seminal Portland Diabetic Project studies in cardiac surgery demonstrated intravenous insulin infusions following open-cardiac surgery achieved near normal glycaemia and decreased deep sternal wound infection to similar rates to those without diabetes. Aim: We sought to examine a contemporary cohort of patients undergoing coronary artery bypass graft surgery (CABGS) to evaluate the relationship between diabetes, hyperglycaemia and risk of surgical site infection (SSI) in current-era models of care. Methods: Consecutive patients who underwent CABGS between 2016 and 2018 were identified through a state-..
