This guide compiles information reported by medical schools on their efforts to help students develop a sound code of professional ethics. The introduction opens with background information on an Association of American Medical Colleges (AAMC) 1992 survey of medical schools and on why it is imperative that schools assist medical students' ethical development. The guide's organization follows the medical student's journey with the first chapter addressing admissions. The second chapter covers the orientation to medical school and learning its code of conduct. The third chapter, the longest, treats curricular innovations and focuses on case scenarios drawn directly from students' immediate ethical dilemmas. The fourth chapter addresses evaluation of students. The fifth chapter looks at influencing faculty. The sixth chapter is titled "Teaching Research Ethics" and is by Allan C. Shipp. The seventh chapter examines other initiatives. The final chapter offers a summary and conclusions and draws together the most important recommendations. Each of these chapters reports results from the AAMC study as well as findings from the literature. Of 35 appendices, 25 are cases illustrating ethical dilemmas encountered by medical students. Includes an index of schools named and roster of respondents. An annotated bibliography contains 63 references.) (JB)
