Abstract: Elective surgery in obese adults carries a higher risk of post-operative infection and prolonged hospital stays, and surgeons may postpone surgery for patients with obesity until they lose weight. The present study aimed to determine the efficacy of a dietitian-led very low calorie diet (VLCD)-based model of care with respect to achieving weight loss for obese patients prior to surgery. This mixed-methods study included a medical chart audit of patients referred to a VLCD-based model over 23 months, as well as a survey of recently treated patients and surgeons who utilised the model. Preoperative weight loss targets were set by surgeons, and the dietitian prescribed in idualised VLCD-based treatment. Efficacy was determined as weight loss considered sufficient for surgery, clinical safety of VLCD-based treatment, feasibility, and stakeholder value. Pre ost-intervention differences in clinical measures were explored by paired t-test or Wilcoxon tests as appropriate. Data on seventy-eight eligible patients [mean (SD) 45 (13) years, 90% female, body mass index 44.3 (6.2) kg m A dietitian-led VLCD-based model achieved sufficient weight loss to facilitate elective surgery for most patients. The approach was feasible, highly valued by patients and surgeons, and resulted in perceived surgical benefits.
