Keywords

PCORnet bariatric study; Weight loss; Diabetes risk; Stakeholder involvement; Health systems data; Clinical data research networks; Adjustable gastric band; Roux-en-Y gastric bypass; Vertical sleeve gastrectomy

Key Points

  • In 2014, the PCORnet Obesity Task Force was established to help generate and prioritize obesity research topics. Their work led to a Patient-Centered Outcomes Research Institute (PCORI) funding announcement for two topics: weight loss surgery and effects of antibiotics on weight in children.
  • The PCORnet Bariatric Study assessed the three most commonly used weight loss procedures and impacts on weight loss/gain, improvement in diabetes risk, and adverse events over 1-, 3-, and 5-year periods. 
  • More than 46,000 adults and nearly one dozen health systems helped contribute data in the PCORnet Bariatric Study.

Discussion Themes

The qualitative aims of the PCORnet Bariatric Study will complement the quantitative aims by incorporating interviews with surgeons and bariatric patients. The analysis of the qualitative aims is still ongoing.

The dissemination plan for the PCORnet Bariatric Study includes lay summaries for each of the project aims. When all publications have completed the peer-review process, the lay summaries will be developed and publicly shared.

The PCORnet Bariatric Study is an example of the power of aggregated data using the PCORnet Common Data Model (CDM). Visit the PCORnet CDM webpage to learn more.
