The contributors to this latest volume of Research in the Sociology of Health Care investigate macro-level system issues and micro-level issues involving the socially disadvantaged and underserved. Looking specifically at the factors impacting on health and health care differentials, this book is an examination of the health and health care issues of both patients and providers of care in the United States and around the globe. Chapters focus on linkages to policy, population concerns and patients and providers of care as ways to meet health care needs.
