The UC Davis School of Medicine was one of only seven medical schools in the United States to receive a grade of "A" from the American Medical Student Association for having one of the nation's best conflict-of- interest policies. UC Davis implemented its policy in 2007 banning employees from accepting gifts from any representative or distributor of a manufacturer or company who visits for the purpose of soliciting, marketing or distributing products or information regarding the use of medications, products, equipment and/or services.
