Moral concerns about the authority, power, and trustworthiness of physician
s have become important topics in clinical ethics during the past three dec
ades. These concerns have come to greater prominence with the increasing in
volvement of large-scale private institutions in the organization and deliv
ery of medical services, especially managed care organizations, and with th
e increasing involvement of government in the payment for and organization
and delivery of medical services. When physicians act as the agents of larg
e institutions or,governments, the power of physicians over their patients
increases. The purposes of this article are (1) to reflect briefly on the h
istorical origins of the moral problem of physicians' power in medicine, an
d (2) to introduce the articles in the 1999 annual number of the Journal of
Medicine and Philosophy on topics in clinical ethics.
