Why the study?
Practice guidelines vary across countries regarding the perioperative management of patients with diabetes undergoing major surgery, and whether this variation or different strata of preoperative glycaemic control affect postoperative outcomes has not been investigated on a large scale.
Population
5000 patients with diabetes undergoing elective or emergency surgery
Comparison
Different perioperative management practices and strata of preoperative glycaemic control
Design
Prospective, observational, international, multicentre cohort study
Follow-up
