Cost-effectiveness and budget impact of obesity surgery in patients with type 2 diabetes in three European countries(II).

Background: This study aimed to establish a payer-perspective cost-effectiveness and budget impact model of adjustable gastric banding (AGB) and gastric bypass (GBP) vs. conventional treatment (CT) in patients with a body mass index (BMI) > or = 35 kg x m(-2) and type 2 diabetes mellitus (T2DM) in Austria, Italy, and Spain.

Methods: A health economics model described in a previous publication was applied to resource utilization and cost data in AGB, GBP, and CT from Austria, Italy, and Spain in 2009.
