Persons trained in philosophical or theological ethics who work in clinical, research, public policy, or other settings where they bring their expertise to bear on the analysis of ethical dilemmas in policies or cases. (Bioethics Thesaurus)

Services provided by an individual ethicist (ETHICISTS) or an ethics team or committee (ETHICS COMMITTEES, CLINICAL) to address the ethical issues involved in a specific clinical case. The central purpose is to improve the process and outcomes of patients' care by helping to identify, analyze, and resolve ethical problems.

The use of systematic methods of ethical examination, such as CASUISTRY or ETHICAL THEORY, in reasoning about moral problems.

The principles of professional conduct concerning the rights and duties of the physician, relations with patients and fellow practitioners, as well as actions of the physician in patient care and interpersonal relations with patient families.

The identification, analysis, and resolution of moral problems that arise in the care of patients. (Bioethics Thesaurus)

The absence of a useful purpose or useful result in a diagnostic procedure or therapeutic intervention. The situation of a patient whose condition will not be improved by treatment or instances in which treatment preserves permanent unconsciousness or cannot end dependence on intensive medical care. (From Ann Intern Med 1990 Jun 15;112(12):949)

Hospital or other institutional ethics committees established to consider the ethical dimensions of patient care. Distinguish from ETHICS COMMITTEES, RESEARCH, which are established to monitor the welfare of patients or healthy volunteers participating in research studies.

Standards of conduct that distinguish right from wrong.

A branch of applied ethics that studies the value implications of practices and developments in life sciences, medicine, and health care.

The religion of the Jews characterized by belief in one God and in the mission of the Jews to teach the Fatherhood of God as revealed in the Hebrew Scriptures. (Webster, 3d ed)

The act or practice of killing or allowing death from natural causes, for reasons of mercy, i.e., in order to release a person from incurable disease, intolerable suffering, or undignified death. (from Beauchamp and Walters, Contemporary Issues in Bioethics, 5th ed)

Clusters of topics that fall within the domain of BIOETHICS, the field of study concerned with value questions that arise in biomedicine and health care delivery.

Abstract standards or empirical variables in social life which are believed to be important and/or desirable.

Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.

The obligations and accountability assumed in carrying out actions or ideas on behalf of others.

The process of making a selective intellectual judgment when presented with several complex alternatives consisting of several variables, and usually defining a course of action or an idea.

The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.

Relatively undifferentiated cells that retain the ability to divide and proliferate throughout postnatal life to provide progenitor cells that can differentiate into specialized cells.

The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.

Progenitor cells from which all blood cells derive.

Cells derived from the BLASTOCYST INNER CELL MASS which forms before implantation in the uterine wall. They retain the ability to divide, proliferate and provide progenitor cells that can differentiate into specialized cells.

Cells with high proliferative and self renewal capacities derived from adults.

Directions or principles presenting current or future rules of policy for assisting health care practitioners in patient care decisions regarding diagnosis, therapy, or related clinical circumstances. The guidelines may be developed by government agencies at any level, institutions, professional societies, governing boards, or by the convening of expert panels. The guidelines form a basis for the evaluation of all aspects of health care and delivery.
