Clinical trials have become a $24 billion industry that is reshaping every aspect of health care development and delivery in the United States and around the world. "Chasing Medical Miracles "is the first book to give readers a behind-the-scenes look at the complicated world of clinical trials and how a multibillion-dollar industry of private companies conducting clinical trials with little oversight has quietly become a major part of the American medical establishment. O'Meara reveals what every health-conscious person needs to know about how drugs, devices, and procedures are tested and approved.
