Physicians, scientists, patients, and the public rely on professional organizations to provide an independent, unbiased forum for presentation of research, publications, and educational activities at their scientific sessions and in scientific publications. Attendees at educational activities sponsored by not-for-profit organizations usually incur financial and other costs. The attendees expect to gain information from leading experts that may modify their behavior and result in a change in patient care. Concerns about real or perceived conflicts of interest among organizations, physicians, scientists, patients, and educators regarding their relationships with the medical products industryhave been debated in the press and in medical journals (1- 2). Concerns about these relationships have been discussed extensively by the Association of American Medical Colleges (AAMC), which issued guidelines for conflict of interest in human subjects' research based on a consensus of a committee including clinicians, scientists, legislators, ethicists, consumers, and representatives from commercial interests (3- 4).
