We aim to describe the state-of-the-art inpatient treatment of AN in real-world reports.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A systematic review of the literature on the major medical databases, spanning from January 2011 to October 2023, was performed, using the keywords: \u201cinpatient\u201d, \u201chospitalization\u201d and \u201canorexia nervosa\u201d. Studies on pediatric populations and inpatients in residential facilities were excluded.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Twenty-seven studies (3501 subjects) were included, and nine themes related to the primary challenges faced in hospitalization settings were selected. About 81.48% of the studies detailed the clinical team, 51.85% cited the use of a psychotherapeutic model, 25.93% addressed motivation, 100% specified the treatment setting, 66.67% detailed nutrition and refeeding, 22.22% cited pharmacological therapy, 40.74% described admission or discharge criteria and 14.81% follow-up, and 51.85% used tests for assessment of the AN or psychopathology. Despite the factors defined by international guidelines, the data were not homogeneous and not adequately defined on admission\/discharge criteria, pharmacological therapy, and motivation, while more comprehensive details were available for treatment settings, refeeding protocols, and psychometric assessments.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Though the heterogeneity among the included studies was considered, the existence of sparse criteria, objectives, and treatment modalities emerged, outlining a sometimes ambiguous report of hospitalization practices. Future studies must aim for a more comprehensive description of treatment approaches. This will enable uniform depictions of inpatient treatment, facilitating comparisons across different studies and establishing guidelines more grounded in scientific evidence.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Level of evidence<\/jats:title>\n                <jats:p>Level I, systematic review.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s40519-024-01665-5","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T11:01:58Z","timestamp":1716202918000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Inpatient treatments for adults with anorexia nervosa: a systematic review of literature"],"prefix":"10.1007","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1524-1272","authenticated-orcid":false,"given":"Federica","family":"Toppino","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8877-0138","authenticated-orcid":false,"given":"Matteo","family":"Martini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1347-7054","authenticated-orcid":false,"given":"Paola","family":"Longo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In\u00eas","family":"Caldas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3564-598X","authenticated-orcid":false,"given":"Nadia","family":"Delsedime","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6213-8378","authenticated-orcid":false,"given":"Raffaele","family":"Lavalle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Raimondi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5826-5664","authenticated-orcid":false,"given":"Giovanni","family":"Abbate-Daga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9385-0332","authenticated-orcid":false,"given":"Matteo","family":"Panero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"1665_CR1","doi-asserted-by":"publisher","first-page":"24","DOI":"10.1111\/imj.14691","volume":"50","author":"P Hay","year":"2020","unstructured":"Hay P (2020) Current approach to eating disorders: a clinical update.
