There is strong evidence that involving patients and service users in healthcare professionals' education has short-term benefits for all involved. Longer term, there has been little evaluation to discover whether this involvement has an effect on the behaviour or practice of health professionals or on health outcomes. This newly published Health Foundation report aims to describe the current state of active patient involvement in the education of health and social care professionals, both in the literature and in practice. It aims to highlight areas for further research and development.
