Who we are — PCORnet Bariatric Study

The PCORnet Bariatric Study (PBS) team are a team of researchers, bariatric surgeons, clinicians who treat people affected by obesity, patients who have had weight loss surgery and their families, and advocacy organizations. We believe each of us has a unique perspective on living with and providing care to people affected by obesity. We work to ensure all members of the team have an equal voice in how we design and carry out the study. 

Our team is made of 3 key groups: The Clinical Data Research Networks, an Executive Bariatric Stakeholder Advisory Group, and the Scientific Core.

 The study is led by 3 principal investigators:

  • David Arterburn, co-principal investigator, Kaiser Permanente Washington Health Research Institute
  • Kathleen McTigue, co-principal investigator, University of Pittsburgh and UPMC
  • Neely Williams, co-principal investigator (patient and community organizer) 

PCORnet Clinical Data Research Networks (CDRNs)

PCORnet CDRNs support this project by contributing de-identified electronic medical record data for analysis, developing our scientific goals, carrying out analyses, and helping to disseminate findings. Eleven CDRNs, representing 41 health systems across the United States, participate in the study.

Executive Bariatric Stakeholder Advisory Group

Our Executive Stakeholders provide feedback on study design and dissemination, and facilitate the engagement of broader stakeholder groups, with the goal to create a more nimble body of professionals who can contribute to the study with the same importance as the leadership core. Each stakeholder is affiliated with a CDRN.

Scientific Core

The Scientific Core includes the scientists and patient investigators who are ultimately responsible for the success of the entire PBS research process, including developing and implementing the research plan, stakeholder engagement, and all dissemination activities.
