The study is a prospective, observational study of adult, non-cardiac, non-obstetric, elective surgical patients conducted over a period of one week. This large-scale clinical audit aims to assess the incidence rates of anaemia and hyperglycaemia amongst elective surgical patients in the Western Cape. A study such as this is essential in the assessment of the incidence rates of abnormal fasting blood glucose levels and reduce the risk of perioperative complications for patients. Preoperative anaemia is a modifiable risk factor and should be identified early and treated appropriately to improve patient outcomes.
