Interventions

  • Program (Systematic Minimal Early Intervention for Eating Disorders) — OTHER
    The AGIS-TCA intervention consists of a structured early proactive support program designed to maintain patient engagement during the waiting period before specialized treatment for eating disorders

Study Details

Eating disorders (EDs) are complex psychiatric conditions-such as anorexia nervosa and bulimia nervosa-often emerging in young adulthood and associated with high morbidity and mortality. Despite their severity, access to specialized care remains difficult, delayed by shame, stigma, and a lack of insight among patients, as well as long waiting times and limited specialized resources. The AGIS-TCA pilot study aims to evaluate the effectiveness of a systematic minimal early intervention designed to reduce the number of patients lost to follow-up between their request for specialized care and the actual start of treatment. This monocentric, low-risk interventional study will be conducted at the Clinique des Maladies Mentales et de l'Encéphale (CMME), GHU Paris Psychiatrie \& Neurosciences. The intervention includes three early, structured telephone calls and five online support group sessions offered during the waiting period for care. The main objective is to determine whether this proactive approach decreases attrition rates ("lost to follow-up") compared with a historical cohort. Secondary objectives include assessing the acceptability of early phone contact, adherence to support groups, and describing the clinical and sociodemographic profiles of patients requesting care or lost to follow-up. The expected benefit is to facilitate timely access to care for vulnerable patients, prevent symptom worsening, and strengthen engagement in treatment pathways. Risks and constraints are minimal, as participation involves only remote interactions without any invasive procedures.

Arms

  • Experimental: AGIS-TCA Intervention Group
    Participants will receive a systematic minimal early intervention designed to maintain engagement during the waiting period before specialized treatment for an eating disorder. The intervention includes: Three structured telephone calls (AT1, AT2, AT3) at approximately day 7, day 45, and day 90 after validation of the care request. These calls aim to provide information, emotional support, and risk prevention guidance, and to maintain motivation for treatment. Five online support group sessions (60 minutes each, every two weeks) led by a multidisciplinary team (specialized nurse, physician, dietitian, psychologist, psychomotor therapist, and peer support worker). Duration: 3 months per participant. Number of Participants: 215 adults. Study Site: Clinique des Maladies Mentales et de l'Encéphale (CMME), GHU Paris Psychiatrie \& Neurosciences.
  • No Intervention: Historical Comparison Group
    A historical cohort of patients who requested specialized care for an eating disorder during the previous year (01/11/2024-31/10/2025), before implementation of the AGIS-TCA program. These patients received standard care procedures, which involved no systematic contact during the waiting period between their request for treatment and the start of care.
