David Rothman gives us a brilliant, finely etched study of medical practice today. Beginning in the mid-1960s, the practice of medicine in the United States underwent a most remarkable--and thoroughly controversial--transformation. The discretion that the profession once enjoyed has been increasingly circumscribed, and now an almost bewildering number of parties and procedures participate in medical decision making.
