About Us

Nationwide, 93 million adults and one in five adolescents have obesity. But the concerns they face go well beyond excess weight. They are at greater risk for heart disease, type 2 diabetes, and cancer, among other health problems.

People with obesity have numerous options to consider when looking for the approach that might work best for them. But for those seeking a surgical solution, finding the right treatment can be as complex as the condition itself.

That’s a challenge that Neely Williams, MDiv, a pastor in Nashville, Tennessee, knows firsthand. She struggled with her weight for 28 years, reaching more than 300 pounds. “The more I weighed, the less I was able to move. And the less I moved, the more I weighed,” she said.

After having weight-loss surgery herself, Williams decided to take action that could help others by becoming the patient co-investigator for a PCORI-funded study of the three most common types of bariatric surgery.

The PCORnet® Bariatric Study was one of the first designed to test the capabilities of PCORnet®, The National Patient-Centered Clinical Research Network, which was developed with PCORI funding. PCORnet securely leverages networks of clinical information from millions of patients to help conduct large-scale health research more efficiently and quickly at a lower cost than would otherwise be possible.
