Study summary:

Background: The length of stay and the mortality rate in the year after admission for patients with severe anorexia nervosa is higher than for other psychiatric conditions. We have found that actively involving the family in shared management reduces the readmission rate and improves both patient and family well being. Aim: The aim of this study is examine whether adding self management materials for carers and patients improves both patient and carer outcomes and service use in the year following specialist inpatient treatment for patients with severe anorexia nervosa. Setting. This is a multicentre study set in the NHS and independent eating disorder inpatient centres in the UK. Participants are people with anorexia nervosa age 17 and above admitted for inpatient care or daycare and their carers. Comparison: Patients and carers are randomised to treatment as usual alone or with the addition of the self management materials. Intervention: The intervention involves access to self management tools, which support the individual and the family. These contain workbooks, DVD, vodcasts and instant messages and e mail support from a mentor. Patients’ and carers’ wellbeing are measured on admission and at regular intervals over the following 18 months using questionnaires and interviews. In addition, service use, costs, and the role of prospective mediators and moderators of clinical outcomes are measured.
