Medical ethics in the 1990s. Emphasis on death-and-dying issues will continue but social concerns will command increased attention.

During the 1990s medical ethics will undergo changes. Individual clinical issues, especially those related to death and dying, will continue to create conflict and preoccupy hospital staffs. But professional ethicists will focus on social concerns more frequently than they have in the past. Following are some of the most crucial ethical issues and directions they are likely to take in this decade: Clinical practice and the law will move toward less demanding standards of proof regarding the withdrawal of treatment from patients who are no longer competent. Public policy will set more lenient standards for judging whether a person would refuse artificial nutrition and hydration if he or she were able. Unless sensible people strengthen the distinction between active and passive euthanasia, more physicians and legislatures will move toward physician-assisted suicide. Those proposing a higher-brain definition of death, as opposed to whole-brain definitions, will gain ground with the general public, but not with legislators. New transplantation technologies will increase medical options but create more problems with paying for the procedures. As techniques are perfected, ethical questions will focus more on financing than on the source of transplantable material. AIDS treatment priorities will clash with other medical demands (e.g., treatment for breast cancer), and concerns about protecting both providers and patients from contracting AIDS will move policy toward routine testing. Progress in public argument will be made on the abortion issue. Members of ethics committees will have to be trained to address financing issues. Some medical schools and residency programs will add courses on the concept of character and on character development to their ethics programs.(ABSTRACT TRUNCATED AT 250 WORDS)
