Institutional ethics committees: what, how, and why.

Because institutional ethics committees can reduce the risk of tragic mistakes by clinical decision makers and provide interdisciplinary input into decisions, they may be a requirement for all hospitals by the end of this decade. Ethics committees should not in themselves be decision-making entities, however. Their proper functions are to advise physicians, patients, and families; facilitate communication; provide in-house education; assist in policy formulation; mediate between ethical theory and concrete medical judgments as well as between the institution's values and those of the larger community; provide support for those involved in painful decisions; and minimize the institution's vulnerability to litigation. Although ethics committees have been endorsed by federal agencies, a presidential commission, and numerous health care organizations, several obstacles remain. Physicians are afraid that their decisional prerogatives will be wrested from them; a committee could become a rubber-stamp organ for one powerful member, one special-interest group, or one perspective, confidentiality policies would have to be extended to nonhospital committee members; and medical personnel feel threatened by the exposure of errors or bad judgment. Nonetheless, ethics committees are a promising structural adjustment to ethical pressures exerted by new technology and the growing number of health care disciplines.
