This paper reports on some of the findings from a collaborative study funded by the Big Lottery and led by Crossroads Caring for Carers about carers for people with mental health problems. The protection and use of information in mental health are firmly rooted in ethics and professional codes, law and policy, as well as values and professional practice. While government initiatives have attempted to augment the role and rights of carers, policy guidance involving information sharing between professionals and carers has failed to deal with the practical dilemmas of patient confidentiality.
