There are many controversial issues surrounding ethics in study design and conduct of human subjects research. In this review we briefly touch on the origin of ethics in clinical research and how the current regulations and standards came into practice. We then discuss current controversies regarding informed consent, conflicts of interest, institutional review boards, and other relevant issues such as innovative procedures and quality improvement projects. The question of whether we need more standards is a very important yet challenging one to which there is no simple answer. We address this question by reviewing and commenting on relevant literature. We conclude that what is needed are not more standards per se, but rather refinement and uniformity of current standards, and their interpretation and application both to protect human subjects and to advance medicine.
