Program (Systematic Minimal Early Intervention for Eating Disorders): 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 summary

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.

Eligibility

Primary outcome measure(s)

• Rate of Patients Lost to Follow-Up — 7 months
  The primary outcome is the difference in the rate of patients lost to follow-up between the intervention group (AGIS-TCA program) and a historical control cohort. A patient is considered lost to follow-up if they have submitted a valid request for specialized care (excluding cases of reorientation) but have not attended the evaluation days at the Eating Disorders Expert Center (CMME) or completed their intake process within 10 months of their initial request.
