Emerging from out of the shadows? Service user and carer involvement in systematic reviews

The systematic review methodology literature refers to the importance of involving stakeholders, including service users and carers, in the research. However, compared with other aspects of the methodology, this aspect of conducting systematic reviews is under-developed and the practice of involvement appears highly variable. This article draws on the experience of working with service users and carers in one systematic review to review the barriers to participation and the components of effective involvement. It suggests that quality standards can be identified for service user and carer involvement in systematic reviews, which will benefit policy and practice development.
