• Research summary

  Background
  Several studies have demonstrated that patients undergoing major vascular surgery have a significant incidence of malnutrition, with a higher incidence in patients undergoing abdominal aortic aneurysm repair. We know that malnutrition can have an adverse effect on outcome and is associated with increased postoperative morbidity, poor wound healing and longer length of hospital stay. This can have a significant cost implication on the healthcare system.
  A variety of nutritional scoring systems have been found to be valuable in predicting outcome in those undergoing major surgery when used alone but there is no evidence to suggest which nutritional scoring system best correlates with outcome in this patient group.

  Aim
  To assess the nutritional status of a cohort of patients undergoing major elective, semi-elective or urgent vascular surgery (abdominal aortic aneurysm repair, Infra-inguinal surgery and limb amputations) using four nutritional scoring systems: Malnutrition Universal Screening Tool (MUST), Short Nutrition Assessment Questionnaire (SNAQ), Subjective Global Assessment (SGA), and Mini Nutritional Assessment (MNA), to determine the best validated nutrition screening tool for use in vascular patients and establish if a correlation exists with prediction to postoperative clinical outcome. The primary outcome measured is wound infection (scored using a modified ASEPSIS wound scoring system). The secondary outcomes are: length of hospital stay, and place of discharge (home, residential or nursing care, rehabilitation centre).

  Expected Outcome
  To validate a nutritional scoring system that predicts clinical outcome for use in patients undergoing major vascular surgery

  Implications
  The identification of a nutritional scoring system that best correlates with surgical outcome in a cohort of vascular patients can be used as part of a coordinated multidisciplinary team approach for the provision of nutritional support to these patients. This will aid to improve nutritional status during the perioperative phase of their surgical journey, with the aim of reducing the rate of postoperative complications and improving cost effectiveness.
