Background: People with severe learning disabilities and complex needs are more likely to experience delayed discharge from hospital; however, there is little research into their experience in hospital and as they move out as part of the Transforming Care Programme. Methods: Six family members of people with complex needs who had moved out of hospital took part in four focus groups co-facilitated with an expert-by-experience consultant. Participants' relatives had hospital admissions that ranged from 6 weeks to 11 years. Transcripts were analysed using reflexive thematic analysis. Additional reflections are included from an expert-by-experience consultant to capture their unique perspective. Results: Family members reported stories of abuse in hospital and parallel experiences of institutionalisation and trauma, resulting in long-lasting impacts on themselves and their relative. Family members felt let down and undervalued by professionals. They described relief when their relatives moved out of hospital, but there were on-going difficulties accessing the right support in the community and so stability felt fragile. Conclusions: Key recommendations to support community living include respecting family members' expertise, improving partnership working and offering psychological support for family members and people with complex needs post-discharge.
