title: Effect of source of funding on weight loss up to 3 years after gastric banding.
abstract: BACKGROUND
  Laparoscopic adjustable gastric banding (LAGB) is a popular choice for patients seeking weight loss surgery. Since behavioural change appears to play a role in weight loss outcomes we postulated that publicly funded patients might not do as well as self-payers. This series examines the effect of public funding versus self-pay on patients undergoing LAGB over 1, 2 and 3 years.
  
  
  METHODS
  Consecutive non-randomised cohort series of patient undergoing LAGB over 5 years (September 2003 to December 2008) in a single unit. Age, sex, funding route, body mass index (BMI) and complications were recorded. Per cent excess weight loss (EWL) and the Reinhold criterion for success (proportion achieving 50 % EWL) were assessed.
  
  
  RESULTS
  Ninety-nine patients were publicly funded, and 250 patients were self-payers. Initial BMI was significantly higher in publicly funded patients (46.6 vs. 42.3 kg/m(2), p < 0.001) with a higher proportion of males (22.2 vs. 6.0 %, p < 0.001). Mean % EWL was significantly less for publicly funded patients at 1 year (38.1 vs. 53.5 %, p < 0.001) and 2 years (49.6 vs. 64.1 %, p < 0.001), but not at 3 years (59.7 vs. 61.8 %, p = 0.784). Fewer publicly funded patients achieved 50 % EWL at 1 year (24.5 vs. 50.2 %, p < 0.001), but with no significant difference at 2 years (54.8 vs. 67.0 %, p = 0.140) or 3 years (55.2 vs. 66.0 %, p = 0.349).
  
  
  CONCLUSIONS
  Self-pay patients initially achieved more % EWL and greater success in reaching 50 % EWL after LAGB, but this difference was not maintained. The results suggest that patient motivation, using self-pay as a surrogate marker, may affect early results, but the operation itself is the main determinant of weight loss at 3 years.
