Experiences of intensive treatment for people with eating disorders: a systematic review and thematic synthesis.

Background: Eating disorders are complex difficulties that impact the individual, their supporters and society. Increasing numbers are being admitted to intensive treatment settings (e.g., for inpatient treatment, day-patient treatment or acute medical treatment). The lived experience perspectives of what helps and hinders eating disorder recovery during intensive treatment is an emerging area of interest. This review aims to explore patients' perspectives of what helps and hinders recovery in these contexts.

Methods: A systematic review was conducted to identify studies using qualitative methods to explore patients' experiences of intensive treatment for an eating disorder. Article quality was assessed using the Critical Appraisal Skill Programme (CASP) checklist and thematic synthesis was used to analyse the primary research and develop overarching analytical themes.

Results: Thirty articles met inclusion criteria and were included in this review. The methodological quality was mostly good. Thematic synthesis generated six main themes; collaborative care supports recovery; a safe and terrifying environment; negotiating identity; supporting mind and body; the need for specialist support; and the value of close others. The included articles focused predominantly on specialist inpatient care and were from eight different countries. One clear limitation was that ethnicity data were not reported in 22 out of the 30 studies. When ethnicity data were reported, participants predominantly identified as white.

Conclusions: This review identifies that a person-centred, biopsychosocial approach is necessary throughout all stages of eating disorder treatment, with support from a sufficiently resourced and adequately trained multidisciplinary team. Improving physical health remains fundamental to eating disorder recovery, though psychological support is also essential to understand what causes and maintains the eating disorder and to facilitate a shift away from an eating disorder dominated identity. Carers and peers who instil hope and offer empathy and validation are valuable additional sources of support. Future research should explore what works best for whom and why, evaluating patient and carer focused psychological interventions and dietetic support during intensive treatment. Future research should also explore the long-term effects of, at times, coercive and distressing treatment practices and determine how to mitigate against potential iatrogenic harm.
