Learning medical professionalism is a challenging, evolving, and life-long endeavor. Professionalism in Medicine: A Case-Based Guide for Medical Students helps begin this process by engaging students and their teachers in reflection on cases that resonate with the experiences of life in medicine. Through the book’s seventy-two cases, commentaries, videos, and literature-based reviews, students explore the many challenging areas of medical professionalism. Readers will appreciate the provocative professionalism dilemmas encountered by students from the pre-clinical years and clinical rotations and by physicians of various specialties. Each case is followed by two commentaries by writers who are involved in health care decisions related to that case, and who represent a wide variety of perspectives. Authors represent 46 medical schools and other institutions and include physicians, medical students, medical ethicists, lawyers, psychologists, nurses, social workers, pharmacists, health care administrators, and patient advocates.
