Brief Summary

During the management of chronic illnesses, the day hospital (DH) serves as a brief and effective alternative to traditional hospitalization, offering access to multidisciplinary care. Indeed, patients can benefit from a range of therapeutic tools provided by a multidisciplinary care team while remaining in their living environment. Numerous structures exist for the management of eating disorders, but primarily for severe cases, often following hospitalization, before transitioning to outpatient care. There is no alternative for the initial management of these patients.

The DH for the evaluation and early intervention in recent forms of anorexia nervosa at Maison de Solenn serves as a rapid entry point to specialized care. It allows for a thorough assessment and sustained management of eating disorders. Our hypothesis is that a multidisciplinary, intensive, and early intervention for patients with anorexia nervosa and their families in a day hospital would improve the short, medium, and long-term prognosis of the disease compared to conventional multidisciplinary outpatient care. It would also enhance the family's experience of this pathology and their coping skills.

Detailed Description

The patients recruited will come from the active consultation file of the inclusion center (spontaneous consultations, referrals from healthcare professionals, etc.), whether they have had an initial consultation or not. All patients admitted to day hospital during the study period who meet the inclusion criteria will be considered. A first evaluation consultation for mental anorexia will be conducted for all patients, including a somatic and psychological assessment, as well as a consultation with a dietitian. If eligible, the patient and their family will be offered participation in day hospital (for the next session or the following one, depending on availability). In case of refusal, regardless of the reason (parents' availability, excessive distance from home, lack of motivation, etc.), patients will receive regular care in outpatient consultations. For the qualitative study, parents participating in day hospital for their adolescent will be offered inclusion in this research protocol.

The inclusion of young patients will take place over two calendar years (24 consecutive months) for the characterization of the active file. The study will continue for 5 years after the inclusion of the last patient in the study to investigate the outcome. In total, data collection for this research will last a maximum of 84 months (24 months of recruitment and a 5-year follow-up).

Visit 1 - Inclusion: collection of non-oppositions, initial clinical evaluation, then proposal to participate in the day hospital program:

• In case of refusal or impossibility of the day hospital program: multidisciplinary follow-up "as usual" at the consultation center (outpatient group).
• In case of acceptance of the day hospital program (day hospital group): scheduling of 10 to 12 sessions over 12 weeks during a program session, followed by a new evaluation at the end of the program. Outpatient follow-up thereafter.

Outpatient follow-up consists of appointments with the psychiatrist, pediatrician, and dietitian, on average, every month.

Follow-up visits:

• Day hospital group only - at approximately 12 weeks: Visit 1bis: clinical evaluation at the end of the program + semi-structured interviews with parents
• Visit 2 - at 6 months: evaluations, with a search for clinical events + semi-structured interview with patients (either at V2 or V3)
• Visit 3 - at 12 months: evaluations, with a search for clinical events + semi-structured interview with patients (either at V2 or V3)

End of research visit:

• Visit 4 - at 5 years: evaluations, with a search for clinical events

Visits V2, V3, and V4 can be conducted by phone. Visit V4, not necessarily planned as part of the adolescent's follow-up, may be added to care if necessary. It can be conducted by phone, depending on the adolescent's choice.

For participants who have taken part in the day hospital program or outpatient follow-up before the implementation of this protocol and who meet the inclusion criteria, the information sheet will be provided to them during a consultation by an investigator, and non-opposition will be obtained at the next consultation. In case of agreement to participate, data from already conducted visits will be collected retrospectively, and patients will then be contacted for the yet-to-be-performed assessment visits at 6 months (if applicable), 1 year (if applicable), and 5 years.
