Effectiveness of Gastric Sleeve vs. Gastric Bypass for Cardiovascular Disease (ENGAGE-CVD)
This study will include only bariatric surgery patients from Kaiser Permanente Southern California and is designed to achieve the following aims: 1) compare the effectiveness of vertical sleeve gastrectomy (VSG) and Roux-en-Y Gastric Bypass (RYGB) in remission of risk factors for cardiovascular disease (CVD) and reduction in overall CVD risk using advanced statistical and econometric techniques.; 2) compare VSG and RYGB surgical safety using similar methods; and 3) understand the treatment effect heterogeneity in remission of CVD risk factors, reduction in overall CVD risk, and safety outcomes for patients with different racial/ethnic backgrounds, sexes, and disease burdens at the time of surgery.

PCORnet Bariatric Study
This study is designed to address the following aims in over 30 clinical sites participating in the national Patient-Centered Outcomes Research Network (PCORnet) Bariatric Study: Aim 1: To what extent does weight loss and weight regain differ across bariatric surgical procedures (Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding) at 1, 3, and 5 years? Aim 2: To what extent does bariatric surgery lead to improvements in diabetes risk at 1, 3, and 5 years? Aim 3: What is the frequency of adverse events following different bariatric surgical procedures at 1, 3, and 5 years? Aim 4: To elicit patient preferences around the risks and benefits regarding the choice of (a) whether to undergo bariatric surgery; (b) which bariatric procedure to utilize; and (c) follow-up care after bariatric surgery.
