Diabetes in day case general and vascular surgery: A multicentre regional audit.

Background: People with Diabetes Mellitus (DM) are at increased risk of postoperative complications if their HbA1C readings are not well controlled. In the UK, there are clear national guidelines requiring all people with DM to have HbA1C blood testing within 6months before undergoing surgery and that these readings should be below 69 mmol/mol if this is safe to achieve. The aim of this study was to determine whether hospitals in the region were compliant with the guidelines.
