Evidence-Based Prevention Workgroup Member
HCPLAN members play a vital role in advancing healthier communities and stronger healthcare connections. In June 2026, Kevin Volpp, a member of the Evidence-Based Prevention Workgroup, shared insights on his work and the issues shaping value-based care.
How is the University of Pennsylvania or the American Heart Association (AHA) advancing value-based care?
![]()
“The University of Pennsylvania has been a leader in both conducting research designing and evaluating value-based care programs nationally and in participating in a variety of value-based care programs as a health system.
The American Heart Association (AHA) has released major policy statements calling for cardiovascular care payment models that are person-centered and tied to outcomes rather than volume and through its “Value in Healthcare Initiative” brought together several stakeholders to envision value-based cardiovascular care. AHA is also leading evidence-generation in food is medicine through its Health Care by Food Initiative (HCXF), which can address upstream drivers of health cost effectively.”
What measurable outcomes have resulted from this approach?
![]()
“AHA has been a leader in the development of clinical guidelines that have supported the development of several quality improvement programs that have resulted in improvements in blood pressure, cholesterol, diabetes, readmissions, and heart and stroke outcomes, often as part of value-based contracts. Through the HCXF Initiative, AHA is seeing some impressive results on clinical outcomes; one recent food is medicine intervention demonstrated a 52% reduction in hospitalization rates for a population of patients with heart failure.”
How does this work align with the HCPLAN’s Evidence-Based Prevention priorities? (e.g., Nutrition, Evidence-Based Prevention Continuum)
![]()
“This work aligns with the HCPLAN’s priorities in building evidence on what types of programs are effective and cost effective in different clinical contexts. AHA is leading the way in creating this evidence on food is medicine systematically — evidence that is needed for payers to make determinations on what food is medicine programs to cover, for whom, and for how long.”
In one sentence, what is your organization’s “why” for value-based care?
![]()
“Value-based care is a way to improve health rather than simply treating disease while achieving better outcomes in a manner that is more financially sustainable.”
What aspect of your current work with the HCPLAN are you most excited about, and why?
![]()
“It is exciting to be in close contact with leaders at CMS and many other organizations to discuss how we can advance at scale the use of effective strategies to prevent disease to develop a more proactive system of health care within the US.”
