Universal health coverage.

Although over 12% of our gross national product is spent on health care, approximately 14% to 17% of Americans are not covered by any form of health insurance. The cost, benefits, and deficiencies of private insurance and government programs are discussed in this article. The increasing percentage of persons surviving into older age, improved technology, patient demands and expectations, administrative costs, medical malpractice and defensive medicine, and other factors contribute to the steadily increasing cost of care. Physicians must participate in health care reform or passively accept determinations made in their absence.
