Abstract

The medical costs for a type 2 diabetes patient are two to four times greater than the costs for a patient without diabetes. Bariatric surgery is the most effective weight loss therapy and has marked therapeutic effects on diabetes. We estimate the economic effect of the clinical benefits of bariatric surgery for diabetes patients with BMI ≥35 kg/m.

Using an administrative claims database of privately insured patients covering 8.5 million lives 1999-2007, we identify obese patients with diabetes, aged 18-65, who were treated with bariatric surgery identified using HCPCS codes. These patients were matched with non-surgery control patients on demographic factors, comorbidities and healthcare costs. The overall return on investment (RoI) associated with bariatric surgery was calculated using multivariate analysis. Surgery and control patients were compared post-index with respect to diagnostic claims for diabetes, diabetes medication claims and adjusted diabetes medication and supply costs. Surgery costs were fully recovered after 26 months for laparoscopic surgery. At month 6, 28% of surgery patients had a diabetes diagnosis, compared to 74% of control patients (p<.001). Among pre-index insulin users, insulin use dropped to 43% by month 3 for surgery patients, versus 84% for controls (p<.001). By month 1, medication and supply costs were significantly lower for surgery patients (p<.001).

The therapeutic benefits of bariatric surgery on diabetes translate into considerable economic benefits. These data suggest that surgical therapy is clinically more effective and ultimately less expensive than standard therapy for diabetes patients with BMI ≥35 kg/m.
