Bioethics

Nature And Scope Of Bioethics

Against the backdrop of advances in the life sciences, the field of bioethics has a threefold mission: (1) to raise important questions about the general practice of medicine and the institutions of health care in the United States and other economically advanced nations, (2) to wrestle with the novel bioethical dilemmas constantly being generated by new biomedical technologies, and (3) to challenge the presumptions of international and population-based efforts in public health and the delivery of health care in economically underdeveloped parts of the globe. While attention to the ethical dilemmas accompanying the appearance of new technologies such as stem cell research or nanotechnology can command much of the popular attention devoted to the field, the other missions are of equal importance.

At the core of bioethics are questions about medical professionalism, such as: What are the obligations of physicians to their patients? and What are the virtues of the "good doctor"? Bioethics explores critical issues in clinical and research medicine, including truth telling, informed consent, confidentiality, end-of-life care, conflict of interest, nonabandonment, euthanasia, substituted judgment, rationing of and access to health care, and the withdrawal and withholding of care. Only minimally affected by advances in technology and science, these core bioethical concerns remain the so-called bread-and-butter issues of the field.

The second mission of bioethics is to enable ethical reflection to keep pace with scientific and medical breakthroughs. With each new technology or medical breakthrough, the public finds itself in uncharted ethical terrain it does not know how to navigate. In the twenty-first century—what is very likely to be the "century of biology"—there will be a constant stream of moral quandaries as scientific reach exceeds ethical grasp. As a response to these monumental strides in science and technology, the scope of bioethics has expanded to include the ethical questions raised by the Human Genome Project, stem cell research, artificial reproductive technologies, the genetic engineering of plants and animals, the synthesis of new life-forms, the possibility of successful reproductive cloning, preimplantation genetic diagnosis, nanotechnology, and xenotransplantation—to name only some of the key advances.

Bioethics has also begun to engage with the challenges posed by delivering care in underdeveloped nations. Whose moral standards should govern the conduct of research to find therapies or preventive vaccines useful against malaria, HIV, or Ebola—local standards or Western principles? And to what extent is manipulation or even coercion justified in pursuing such goals as the reduction of risks to health care in children or the advancement of national security? This population-based focus raises new sorts of ethical challenges both for health care providers who seek to improve overall health indicators in populations and for researchers who are trying to conduct research against fatal diseases that are at epidemic levels in some parts of the world.

As no realm of academic or public life remains untouched by pressing bioethical issues, the field of bioethics has broadened to include representation from scholars in disciplines as diverse as philosophy, religion, medicine, law, social science, public policy, disability studies, nursing, and literature.
