Efficacy of a dietitian‐led very low calorie diet (VLCD) based model of care to facilitate weight loss for obese patients prior to elective, non‐bariatric surgery
Background 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.

Zusammenfassung: | Background
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.
Methods
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 individualised VLCD‐based treatment. Efficacy was determined as weight loss considered sufficient for surgery, clinical safety of VLCD‐based treatment, feasibility, and stakeholder value. Pre/post‐intervention differences in clinical measures were explored by paired t‐test or Wilcoxon tests as appropriate.
Results
Data on seventy‐eight eligible patients [mean (SD) 45 (13) years, 90% female, body mass index 44.3 (6.2) kg m–2] demonstrated significant mean (SD) weight loss of 7.4% (5.3%) body weight (P |
