Mary-Jo DelVecchio Good, professor of social medicine at Harvard Medical School, will work on three projects related to how the culture of medicine and the organization of health care contribute to disparities in medical treatment and health care by race, ethnicity, and class. Why do such disparities exist? How should we critically analyze current data, assess limitations, and include multiple perspectives in addressing this topic? Taking such questions as her starting point, Good will write a book based on her own research and current relevant literature, illustrating how the relationship of the U.S. medical culture to health care disparities is multidimensional, subtle, and confounded by diverse hierarchies of valued knowledge. Good will also participate in a Russell Sage Working Group on diversity in health care and contribute to an edited volume prepared by the group.
