Cost-Effectiveness of Bariatric Surgery: Should it Be Universally Available?Su-Hsin ChangWashington University in Saint Louis - Division of Public Health Sciences Carolyn Stollaffiliation not provided to SSRN Graham A. ColditzWashington University in St. Louis, Division of Public Health Sciences July 8, 2011 Maturitas, Forthcoming Abstract: This paper is the first to conduct cost-effectiveness analyses of bariatric surgery comparing obese patients with obesity-related diseases to obese people without comorbidities across different BMI categories, using the meta-analysis results of surgery outcomes for our effectiveness inputs. We find that surgery treatment is in general cost-effective for people whose BMI is greater than 35 kg/m2 with or without obesity-related comorbidities, and it is even cost-saving for super obese (BMI ≥ 50 kg/m2) with obesityrelated comorbidities. Our results also suggest that surgery can be cost-effective for the mildly obese (BMI ≥ 30 kg/m2). The bottom line is that bariatric surgery should be universally available to all classes of obese people.
