Healthcare ethics committees (HEC) have emerged as institutional forums for addressing bioethical dilemmas. Psychiatrists have important roles to play on these committees. Their skills in group process assessment, mental status examination, and character assessment have diverse applications. Psychiatrists can facilitate communication within the committee and as HEC-based clinical ethics consultants. HECs must be concerned with how they arrive at ethical decisions, guarding against political influence or individual monopolization. Psychiatrists can assist these efforts as organizational consultants to HECs. The perception of (...) psychiatrists as reflective, tolerant of ambiguity, humanizing, and approachable about ethical aspects of health care suggests they would make excellent committee leaders. Psychiatrists also have important committee roles to play as ethics educators and policy makers. More demographic data is needed to investigate psychiatrist participation on HECs. Studies of how they are perceived by their ethics committee colleagues may reveal new roles and potential pitfalls for HEC psychiatrists. (shrink)
