PCORnet Bariatric Study
The Bariatric Surgery study will examine three main methods of bariatric surgery: gastric bypass, adjustable gastric banding, and sleeve gastrectomy. The study will review electronic health records from 60,000 patients who had one of these three procedures in the past 10 years and include information on 17,000 people with diabetes and 900 adolescents ages 12-19 who have had bariatric surgery. With the increase of the use of bariatric surgery to treat obesity in past 20 years, the PCORnet Bariatric study wants to investigate the benefits, complications, potential risks, and other outcomes associated with the procedure.
The two-year observational study will address three aims: 1) to compare how patient’s weight loss and regain differs across the three bariatric surgical procedures, 2) to compare rates of diabetes improvements or relapse over time after surgery, and 3) to research the frequency of complications or harms following these procedures.
