Abstract

INTRODUCTION:

The increasing prevalence of obesity has now become a global concern. Forecasts of its health and financial ramifications have prompted the need for effective interventions. Bariatric surgery is an effective measure to control obesity and its related comorbidities, but its high up-front costs have raised questions about its cost-effectiveness. In this study we evaluated the health care-related direct cost savings after bariatric surgery.

METHODS:

Data were prospectively obtained from patients who underwent bariatric surgery between May 2008 and April 2011, and a review was performed. These patients' annual cost of regular medications, hospital admissions and outpatient clinic visits were compared with the postoperative costs of these services. Data were collected from January 2005 to April 2012.

RESULTS:

The analysis included 88 patients, 17 of whom were men and 71 were women. The procedures included 36 laparoscopic adjustable gastric banding, 33 sleeve gastrectomies and 19 Roux-en-Y gastric bypasses. All procedures were laparoscopic. Data were collected from patients during a median preoperative period of 60 months (range, 42-75 months) and a median postoperative period of 24 months (range, 12-45 moths). Annual savings were £11 452 on medications, £16 420 on hospital admissions and £2532 on outpatient clinic visits. Total annual savings were £30 404.

CONCLUSION:

Given the rising prevalence of morbid obesity, bariatric surgery is a cost-effective treatment for morbid obesity and should be made available to morbidly obese patients.
