Aftercare for participants in clinical research: ethical considerations in an asthma drug trial.

The issue of aftercare for participants in clinical research was explored in the context of an asthma drug trial. Although there may be financial constraints and practical difficulties with implementation, the results show that it may be feasible for clinical investigators and commercial sponsors to take on some limited responsibility for the medical care of research subjects after clinical trials. However, the ethical implications for this practice remain unclear. On the one hand, society may have a moral obligation to compensate and reward some of its members who assume the risk of research subjects for the benefit of society as a whole. On the other hand, the promise of aftercare may provide an inducement to volunteers which, under certain conditions may be considered morally wrong and scientifically unsound.
