Ancillary care duties: the demands of justice.

Ancillary care is care that research participants need that is not essential to make the research safe or scientifically valid and is not needed to remedy injuries that eventuate as a result of the research project itself. Ancillary care duties have recently been defended on the grounds of beneficence, entrustment, utility and consent. Justice has also been mentioned as a possible basis of ancillary care duties, but little attention has been paid to this approach. In this paper, the author seeks to rectify this omission by arguing that ancillary care duties can be based on a principle of justice as rectification.
