The risks associated with surgery are elevated in patients with diabetes mellitus. For this reason, preoperative diagnostics frequently include the measurement of blood glucose and haemoglobin A1c (HbA1c), but it is unclear whether these tests contribute to improved perioperative or postoperative outcomes. ⋯ Preoperative blood glucose testing and testing for HbA1c is not required in nondiabetic patients unless there are clinical sings arousing suspicion. Patients scheduled for vascular and orthopaedic surgery carry an elevated risk justifying preoperative testing for blood glucose or HbA1c as a screening tool.
