Abstract

Clinical research employing the randomized clinical trial has, traditionally, been understood to pose an ethical dilemma. On the one hand, each patient ought to get the treatment that best meets her needs, as judged by the patient in consultation with her doctor. On the other hand, the method most helpful to advancing our understanding about what treatments are indeed best able to meet patient needs is the randomized trial, which necessitates that each patient's care is decided not by physician judgment or patient choice but instead by random assignment. The tension can be described as a conflict between the interests of individual patients who are sick today, and the interests of the group of people who will become sick in the future and would benefit from advances in medical understanding. How one ought to balance these important and often competing interests is an important ethical question that resists easy resolution.
