P241 Defining patient-centered outcomes for IBD – an international, cross-disciplinary consensus
Bibliographic record
Abstract
Background: Value-based healthcare aims to achieve the best possible health outcomes for the lowest cost. Key to its success involves measuring outcomes that matter most to patients. Currently for inflammatory bowel disease (IBD), registries and clinical trials lack a unifying set of well-defined outcomes, making comparisons between populations difficult. Our goal was to develop a minimum Standard Set of patient-centered outcomes for IBD to provide a common language for outcomes that can be tracked systematically in a variety of healthcare settings. Methods: An international, multidisciplinary working group (n=25) from 12 countries within Europe, North America, Asia, Australia, and South America representing patients, gastroenterologists, surgeons, specialist nurses, IBD registries, patient-reported outcome measure (PROM) methodologists, and patient organisations participated in a series of teleconferences incorporating a modified Delphi process. Systematic review of existing literature, registry data, patient focus groups and open review periods were used to reach consensus on a minimum set of standard outcome measures, the best validated tools for measurement and baseline risk-adjustment variables. Results: A minimum Standard Set of outcomes (Figure 1), preferred tools and measurement frequency was defined by the Working Group for patients (aged ≥16) with IBD. Outcome domains included patient reported outcomes (including quality of life, symptom score, nutritional status and impact of fistulae); survival and disease control (survival, disease activity/remission, colorectal cancer, and anaemia); disutility of care (treatment-related complications); and healthcare utilisation (IBD-related admissions and emergency room visits), all measured at baseline and 6 or 12 month intervals. A single, accessible PROM (IBD-Control questionnaire) was recommended. A core set of patients' baseline characteristics including demographics, baseline clinical and condition factors, and treatment factors were further defined for collection at baseline and tracking annually to enable meaningful comparisons of outcomes between centres, regions, or countries. Figure 1. ICHOM standard set for inflammatory bowel disease. Conclusions: An international, multidisciplinary IBD Working Group that included patients has defined a minimum set of patient-centred outcomes, tools and PROMs for collection in patients with IBD based on evidence, patient input, and specialist consensus. The Standard Set provides a template for meaningful, comparable and easy-to-interpret measures as a step towards achieving value-based healthcare in IBD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
