This course is designed for students who are considering a career in medicine. It focuses attention on complex situations in biology and medicine that require moral reflection, sound judgment and decision on the best outcomes. As such the course is divided into two parts. The first focuses on moral problems in bioethics such as abortion, euthanasia, informed consent, and just distribution of scarce medical resources. The second focuses on professional ethics of medical researchers such as conflicts of interest, interface with industry, and research and publication ethics. Particular attention will be given to departures from the ethics of responsible patient care and the corruption of evidence-based medicine by the pharmaceutical and medical device industries.
