Client Corner: The Dr. Ronald Renzi Story
Researchers, health care communities, and government agencies are just a few of the stakeholders that use our data every day to help improve lives. These stories provide you the opportunity to understand how our data is making a difference.
Chance Meeting Changes Everything
This chance encounter led to PHC4 data and now, with each new data release, has provided the opportunity to hold conversations at local barber shops in Philadelphia discussing high amputation rates in local communities.
Everything changed for Dr. Renzi and the Save Your Soles Campaign when he discovered PHC4 data! By chance, he learned that health care data he had previously spent significant time and effort obtaining for his amputation research was readily accessible through PHC4. This newfound access empowered him to advance his mission to reduce amputation rates and educate stakeholders.
For decades, Dr. Renzi has been a champion for Pennsylvania communities, transforming PHC4 data into action. He uses it to identify communities with high rates of lower-extremity amputations and spark conversations about diabetes with residents and medical professionals. Today, these communities look forward to each new release of PHC4 data, partnering with Dr. Renzi to reduce amputations and improve health outcomes.
As of July 2026, 10 other states have begun replicating Dr. Renzi’s research. His work, published in the Journal of Vascular Surgery and supported by demonstrated success, earned funding from the Foundation to Advance Vascular Cures. His research has also fueled advocacy efforts, helping policymakers recognize the power of data to drive meaningful change.
