The most important purpose of an IRB is to protect the human participants in research. For three major research areas—drugs, medical devices, and genetic information—Dennis J. Mazur shares the methods he has found useful in protecting human participants through the systematic review of scientific protocols and informed consent forms and through adherence to the federal regulations that apply. New members will gain understanding of how proposed research projects are to be reviewed from both scientific and ethical dimensions, how and when to ask key questions of principal investigators, how to work with principal investigators and research teams to ensure the best protection of human participants, and why to schedule regularly spaced reviews of a project that may have adverse outcomes. Containing helpful summaries and checklists throughout and based on Mazur's thirty years of research experience, this accessible and informative guide will give all IRB members the tools they need to protect human lives and facilitate the research process.
