Value-based insurance design (or VBID) can do more than simply reduce out-of-pocket patient costs. By lowering the amount patients pay for the most effective treatments, all healthcare stakeholders benefit. What are the principles of VBID? How can value-based insurance be designed to both improve the health of patients and reign in healthcare costs? What's the role of comparative-effectiveness research data in designing VBID? Dr. A. Mark Fendrick, professor of internal medicine in the School of Medicine, and professor of health management and policy in the School of Public Health, at the University of Michigan in Ann Arbor, defines healthcare value, and stresses the need to remove barriers to the highest-value healthcare services, including preventative care. Dr. William Anderson hosts.
