This book examines the presence and significance of religion and spirituality as it is lived, understood, and managed by doctors, nurses, and chaplains at American hospitals. While a growing body of social scientific research investigates how religion influences individual health, this is the first book to focus institutionally on how hospitals provide religious and spiritual care, what this care means and consists of, and how this care is shaped by the religious ecology of the geographic contexts in which these hospitals are located. The project is based on more than 150 interviews with doctors, nurses, intensive care unit staff and hospital chaplains, a review of historical and policy documents, and two years of ethnographic research at two large academic hospitals. The book manuscript, to be completed during the 2008-09 academic year, synthesizes research in the sociology of religion, health, and organizations and contributes to interdisciplinary and public conversations in sociology, religious studies, congregational studies, and medicine.
