Current ethical practices in research emphasize protecting patient rights before and during a study. Recent ethical discussions have turned to the rights of study participants to learn the results of study findings after the trial is completed. Ethicists have proposed that participants be given a summary of study findings at the conclusion of a study to know how the study and their participation will affect future patients. Some data suggests that subjects really do want to know the study outcome.
In his commentary, Maurie Markman, M.D., of the University of Texas M. D. Anderson Cancer Center in Houston, argues that disclosing the outcome of the study may, in fact, do more harm than the intended good for the patient. Moreover, this approach ignores the fact that at the conclusion of the study, the participant remains a patient. For example, a study participant who receives what turns out to be a less effective treatment may be negatively impacted years later from the knowledge that the treatment they received was not the best, and that as a result their prognosis may be poorer than if they received the "better" treatment. Moreover, there is little the patient can do to change the past treatment.
Dr. Markman advocates a revised informed consent strategy that balances the subject's right to know the results of the study and an individual patient's right to know how the data will specifically impact him or her. This strategy includes pre-study education about the meaning of trial data as statistical probabilities pertaining to general populations rather than a specific individual; the risk that trial data will have no benefit for the individual and may in fact demonstrate poor prognosis; the subjects' choice to receive trial data at the end of the study; and possibility that investigators may decide that trial data is of no relevance to the individual participant and not share the data.
This approach, Dr. Markman argues, "will preserve a research subject's right to be provided study findings, while at the same time responding to an individual's legitimate wish to specifically focus on data which is relevant to his/her future management."
