The nature and limits of the physician's professional responsibilities: surgical ethics, matters of conscience, and managed care.

The nature and limits of the physician's professional responsibilities constitute core topics in clinical ethics. These responsibilities originate in the physician's professional role, which was first examined in the modern English-language literature of medical ethics by two eighteenth-century British physician-ethicists, John Gregory and Thomas Percival. The papers in this annual clinical ethics number of the Journal explore the physician's professional responsibilities in the areas of surgical ethics, matters of conscience, and managed care.
