Specialized, integrative treatment for long-standing eating disorders: early insights and implications

Eating disorders (EDs) are severe and multifaceted psychiatric conditions. Despite advancements in treatment modalities, a substantial gap persists in evidence-based interventions specifically designed for individuals with enduring EDs.

To address this critical clinical need, a specialized residential unit dedicated exclusively to the care of adults with long-standing EDs was launched within the Catalan Public Health System in January 2024. This study introduces the unit's innovative therapeutic model and presents preliminary outcomes related to patient satisfaction, body mass index (BMI), and quality of life.

This preliminary investigation included 18 participants diagnosed with anorexia nervosa (AN) or other specified feeding or eating disorders (OSFED/AN), according to DSM-5 criteria. Each participant underwent a structured clinical interview and completed a comprehensive battery of quantitative and qualitative assessments. These measures evaluated clinical status, psychopathology, personality traits, quality of life, and satisfaction with the treatment received over an average stay of 3-4 months.

Participants had a mean illness duration exceeding 12 years and had previously undergone at least three treatment attempts that did not result in sustained clinical or functional improvement. Despite having 22% high educational attainment, 94% were unemployed. High rates of psychiatric comorbidity were observed. Post-treatment analyses revealed significant improvements in quality of life (p < 0.001) and BMI (p < 0.001). The mean satisfaction score was 85.3 out of 100, aligning with the positive qualitative feedback provided by participants.

Preliminary findings suggest that this novel residential approach yields meaningful improvements in quality of life and psychopathological symptoms, while fostering greater autonomy among individuals with enduring EDs. These results underscore the potential of specialized, long-term care models within public health systems for this underserved population.
