The prevalence and frequency of sexual harassment in medical education is well documented. On the graduation questionnaire administered by the Association of American Medical Colleges in 2003, 15% of medical students reported experiences of mistreatment during medical school. On items that specifically address sexual mistreatment, over 2% of students reported experiencing gender-based exclusion from training opportunities, and unwanted sexual advances and offensive sexist comments from school personnel. Sexual harassment of medical trainees by faculty supervisors is obviously unethical and may also be illegal under education discrimination laws. In two cases in 1998 and 1999, the U.S. Supreme Court clarified that schools may be held liable under Title IX of the Education Amendments of 1972 for the sexual harassment of their students. In 2001, the Office of Civil Rights of the Department of Education released revised policy guidelines on sexual harassment that reflect the Supreme Court rulings. Medical school administrators should undertake formal assessments of the educational environment in their training programs as a first step toward addressing the problem of sexual harassment. The authors recommend that medical schools implement measures to both prevent and remedy sexual harassment in their training programs. These constructive approaches include applying faculty and student education, establishing a system for notification and response, and creating an institutional structure to provide continuous evaluation of the educational environment.
