Background: Treatment for anorexia nervosa (AN) is typically delivered on a continuum of care, starting with outpatient treatment, and moving onto intensive outpatient, day or residential treatment and/or inpatient hospitalisation. However, minimal attention has been afforded to the lived experiences of persons undergoing inpatient treatment for AN. In particular, qualitative literature pertaining to the lived experiences of specialist inpatient or residential treatment of AN remains fragmented and incomplete. The aim of this review was to synthesise current literature exploring patients' lived experiences of residential and inpatient treatment for AN within eating disorder-specific treatment services. Methods: Five databases were searched and a qualitative thematic systematic review and meta-synthesis of 11 studies were conducted. Results: Eleven studies of 159 participants were included. Four meta-themes were constructed from the data: (1) a medical discourse—"I don't think it's individualised here"; (2) restrictive practice—living in a "bubble"; (3) myself, others and "a similar demon"; and (4) I am "not just another anorexic". The data also revealed two cross-cutting themes: (1) more than a single experience; and (2) meaning making and identity. Conclusions: These findings highlight the complex and multifaceted nature of the inpatient treatment experience as well as the inherent conflicts in balancing the necessity of medical and psychological intervention with person-centred treatment approaches in the treatment of AN. Plain English Summary: Treatment for anorexia nervosa (AN) is typically delivered on a continuum of care, starting with outpatient treatment, and moving onto intensive outpatient, day or residential treatment and/or inpatient hospitalisation. However, not much is known about the lived experiences of people going through inpatient treatment for AN. An improved understanding of individuals' treatment experiences is essential in informing the development of new models of care with the potential to improve outcomes. In this systematic review, we examined the lived experiences of individuals going through inpatient treatment for AN available in the current literature. Searching in scientific databases resulted in 10,666 articles, 11 of which met the rigorous inclusion criteria. Four meta-themes and two cross-cutting themes were observed in patient experiences across the studies reviewed. These themes provide insight into the complex and multifaceted nature of the inpatient treatment experience as well as the inherent conflicts in balancing the necessity of medical and psychological intervention with person-centred treatment approaches in the treatment of AN.
