Addressing ethical confusion in deceased donation and transplantation research: the need for dedicated guidance.

Innovative research in deceased donation and transplantation often presents ethical challenges for researchers and those responsible for ethical governance of research. These challenges have been recognized as potential barriers to the conduct of research. We review the literature to identify and describe ethical considerations that may cause confusion or uncertainty in the context of research involving potential deceased donors or deceased donor transplantation. We normatively examine these considerations and discuss their implications for the ethical conduct of research. In addition to the complexities of research involving critically ill, dying or recently deceased individuals, uncertainty may arise regarding the ethical status of various individuals who may be involved in research aimed at improving availability and outcomes of organ transplantation. Consequently, routine ethical guidelines for clinical research may fail to provide clear guidance with regards to the design, conduct and governance of some deceased donation or transplantation studies. Ethical uncertainty may result in delays or barriers to research, or neglect of important ethical considerations. Specific ethical guidance is needed to support research in deceased donation and transplantation as the ethical considerations that arise in the design and conduct of such research may not be addressed in the existing guidelines for human research.
