Review: a narrative review of the published ethical debates in palliative care research and an assessment of their adequacy to inform research governance.

The quality of research, and the resulting quality of evidence available to guide palliative care, is dependent on the ethical decisions underpinning its design, conduct and report. Whilst much has been published debating the ethics of palliative care research, an assessment of the quality and synthesis of the central debates is not available. Such a review is timely to inform research governance. The methodology of this study is based on the principles of systematic reviews. Fifty-seven papers were reviewed following a thorough search, and were critically appraised for their literary quality, the knowledge on which they drew and the research standards they addressed. The debates identified address vulnerability, moral appropriateness, consent, gate-keeping and inclusion and research culture. The quality of debate and the sources of knowledge varied. The debate was rich in quality and knowledge with respect to the protection of the dignity, rights and safety of research participants, but less developed in relation to those of researchers and other staff. There is also little debate about the ethics of reporting of research and the ethics underpinning research leadership. A framework is offered that reconciles the ethical issues raised with potential methodological strategies identified from the review.
