The Symposium on Diversity in the Health Professions in Honor of Herbert W. Nickens, M.D., was convened in March 2001 to provide a forum for health policymakers, health professions educators, education policymakers, researchers, and others to address three significant and contradictory challenges: the continued under-representation of African Americans, Hispanics, and Native Americans in health professions; the growth of these populations in the United States and subsequent pressure to address their health care needs; and the recent policy, legislative, and legal challenges to affirmative action that may limit access for underrepresented minority students to health professions training. The symposium summary along with a collection of papers presented are to help stimulate further discussion and action toward addressing these challenges. The Right Thing to Do, The Smart Thing to Do: Enhancing Diversity in Health Professions illustrates how the health care industry and health care professions are fighting to retain the public's confidence so that the U.S. health care system can continue to be the world's best.
