Return of results: ethical and legal distinctions between research and clinical care.

The return of individual results to research participants has been vigorously debated. Consensus statements indicate that researchers and bioethicists consider the return of research results most appropriate when the findings are clinically relevant. Even when clinical utility is the motivator, however, the return of individual research results is not equivalent to clinical care. There are important differences in the domains of research and medical care, both from a legal standpoint and in terms of the ethical responsibilities of clinicians and researchers. As a corollary, researchers risk promoting a therapeutic misconception if they create quasi-clinical settings for return of clinically relevant research results. Rather, efforts should be focused on clarity in the provision of research results, appropriate caveats and, most important, appropriate referrals when the results may be helpful to consider in medical care.
