Drawing on scholarly critique, lived-experience perspectives, and recent shifts in clinical stance, most notably Dr. Jennifer Gaudiani's formal published disavowal of the term \"terminal anorexia nervosa\", this commentary proposes forward-looking strategies across four domains: terminology, capacity assessment, systemic supports, and integrated care frameworks. We advocate replacing deterministic labels with descriptive terms that honor recovery potential and the full spectrum of patient experience.We examine challenges in evaluating decision-making capacity among individuals with ego-syntonic illnesses, especially when severely malnourished, recommend standardized, multidisciplinary, decision-specific protocols, and acknowledge that patients can retain capacity to make informed choices even when severely ill from an eating disorder.We review systemic barriers, including uneven access to specialized services and the impact of clinician moral distress, and suggest institutional supports such as ethics consultation and peer supervision.Finally, we outline an integrated model that combines specialized eating disorder treatment with palliative principles grounded in supported decision-making, emphasizing autonomy and hope. Research and training priorities include standardizing capacity-assessment tools, developing curricula on clinician resilience and ethics, evaluating outcomes of combined palliative-eating disorder interventions, and co-creating guidelines with lived-experience stakeholders.

These disorders are associated with high rates of medical complications, psychiatric and physical comorbidities, functional impairment, family distress, and financial burden. Despite the severity and increasing prevalence of EDs in youth, advancements in understandings of the pathophysiology and treatment of EDs have remained limited over the past three decades. This trend may be shaped by the chronic underfunding of the field, reliance on small sampled cross-sectional studies, and the notable lack of research focused on youth with EDs from historically underrepresented communities. Current treatment practices demonstrate modest efficacy and often omit the complex, heterogeneous presentations, development, and maintenance of pediatric EDs. Large-scale, multiaxial datasets are necessary to elucidate ED etiology and enable phenotyping. This is a critical step towards implementing future precision psychiatry and personalized treatment advances. In this commentary, we share our experience of conceptualizing a precision ED data and bio-registry, EDBioMAP: Eating Disorder Bio-Registry and Multiaxial Precision Health Platform, and suggest necessary pillars to inform, implement, and drive the successful use of precision psychiatry in pediatric ED care. Effective data utilization requires actionable steps and includes: (1) establishing strategic partnerships; (2) incorporating measurement-based care into clinical practice; (3) collecting novel biological markers; (4) developing minimum datasets; and (5) leveraging predictive modelling techniques. Strategic and standardized data integration is imperative to informing the future use of precision psychiatry for EDs.
