Classic statements of research ethics advise against permitting physician-investigators to obtain consent for research participation from patients with whom they have preexisting treatment relationships. Reluctance about “dual-role” consent reflects the view that distinct normative commitments govern physician–patient and investigator–participant relationships, and that blurring the research–care boundary could lead to ethical transgressions. However, several features of contemporary research demand reconsideration of the ethics of dual-role consent. Here, we examine three arguments advanced against dual-role consent: that it creates role conflict for the (...) physician-investigator; that it can compromise the voluntariness of the patient-participant’s consent; and that it promotes therapeutic misconceptions. Although these concerns have merit in some circumstances, they are not dispositive in all cases. Rather, their force—and the ethical acceptability of dual-role consent—varies with features of the particular study. As research participation more closely approximates usual care, it becomes increasingly acceptable, or even preferable, for physicians to seek consent for research from their own patients. It is time for a more nuanced approach to dual-role consent. (shrink)

Physician-researchers are bound by professional obligations stemming from both the role of the physician and the role of the researcher. Currently, the dominant models for understanding the relationship between physician-researchers' clinical duties and research duties fit into three categories: the similarity position, the difference position and the middle ground. The law may be said to offer a fourth.
