Why them? A systematic review on common factors among youth who receive compulsory treatment for anorexia nervosa

Background: Compulsory interventions, including compulsory nasogastric tube feeding, are sometimes necessary for youth with life-threatening anorexia nervosa. However, these interventions are also potentially traumatic for patients and clinicians alike. Objective: To improve early recognition and prevention of compulsory interventions, we evaluated common factors among youth with anorexia nervosa who receive compulsory treatment. Method: We conducted a systematic literature search of peer-reviewed studies in PubMed, Embase, Medline, PsycINFO, and WOS core collection. Two authors independently screened 7 447 articles and conducted a quality appraisal of the included studies. We thematically synthesised patient, contextual, and treatment factors of youth (≤ 24 years) who received compulsory treatment for anorexia nervosa. Results: We included 16 studies and five themes, with ten subthemes, emerged from the data, most with a medium strength of evidence. Patients exhibited common character traits, various comorbidities, and lives marked by instability or adversity. Furthermore, patients experienced complicated contextual factors, including family dysfunction and social isolation. Discussion: Prolonged and inconsistent treatment histories may increase social isolation and anorexia identification, which in turn may lead to increased treatment resistance and a higher likelihood of compulsory interventions. Conclusion: The diversity of presented factors in this systematic review emphasises the importance of personalised care. Early acknowledgement of factors associated with the illness is crucial for working towards recovery and preventing further deterioration. Furthermore, even when anorexia nervosa diverts all attention to dangerous levels of weight loss, attention to quality of life may help a patient find treatment motivation.
