PHILADELPHIA -- End-of-life issues are one health care's most contentious and painful areas of debate. A year ago, the University of Pennsylvania's Center for Health Incentives and Behavioral Economics (CHIBE) organized a new research program called FIELDS to study end-of-life decision making by patients, families, doctors and hospitals. The FIELDS acronym stands for "Fostering Improvement in End-of-Life Decision Science." In this video from a recent behavioral economics retreat, CHIBE Deputy Director Scott Halpern, MD, PhD, MBE, briefly discusses this new study group.
