Fifty-four veterans (6.3%) had died by the end of 2006. In our Cox models, patients with a BMI greater than 50 (superobesity; hazard ratio [HR], 1.8; P = .04) or a DCG score greater than or equal to 2 (HR, 3.4; P < .001) had an increased risk of death.Conclusion  Superobese veterans and those with a greater burden of chronic disease had a greater risk of death after bariatric surgery from 2000 through 2006.
