This week, hosts Mark Masselli and Margaret Flinter speak with Dr. Kirsten Bibbins-Domingo, Chair of the Department of Epidemiology and Biostatistics at the University of California at San Francisco, who recently chaired a committee at the National Academy of Sciences, Engineering and Medicine on the social determinants of health. She discusses their report on ways to incorporate social care into health care, shifting the American health system towards better management of upstream causes of poor health.
