Nicholas Christakis, M.D., Ph.D., is an internist and
sociologist who conducts research on the socio-cultural
factors that affect the supply, demand, and outcomes of
medical care. He is Professor of Medical Sociology in the
Department of Health Care Policy at Harvard Medical
School. He is also active as an Attending Physician in the
Palliative Medicine Program at Massachusetts General
Hospital, and an Affiliate of the Department of Sociology in
the Faculty of Arts and Sciences, Harvard
University. He co-directs the Robert Wood Johnson Scholars in Health
Policy program at Harvard.
Dr. Christakis' past work has examined the accuracy and role of
prognosis in medicine, ways of improving end-of-life care, factors
associated with hospice use, and the impact of hospice care on the
health of bereaved spouses. His book on prognosis, Death Foretold:
Prophecy and Prognosis in Medical Care, was published by the University
of Chicago Press in 1999 and has been broadly reviewed.
Currently, he is principally concerned with health and social networks,
and specifically with how ill health, health risks, and death in one
person can have like consequences for others in a person's social
network. Some current work is focused on the health benefits of marriage
and on how ill health in one spouse can have cascading effects on the
other spouse. It seems likely that improving the health of one partner
in a marriage can have meaningful effects on the health of the other,
and that both parties would value this - in a way that influences health
policy.
