P585 Examining faecal incontinence and its impact on health-related quality of life in patients with Crohn’s perianal fistulas: results from a multi-country burden of illness study
Bibliographic record
Abstract
Abstract Background Perianal fistulas (PAF) are a common complication associated with Crohn’s disease (CD), and patients with Crohn’s perianal fistulas (CPF) are more likely to experience faecal incontinence (FI) than patients with CD without PAF (non-PAF CD). A global study was conducted to assess the burden of illness in patients with CPF compared with patients with non-PAF CD. Here, we present data on the level of FI and its impact on quality of life (QoL). Methods This cross-sectional study was conducted in seven countries (France, Germany, Spain, UK, Canada, Australia and Japan) in patients aged ≥21 and ≤90 years with self-reported physician-diagnosed CD. Patients were classified as having non-PAF CD (cohort 1) or CPF without PAF-related surgery (cohort 2) or CPF with PAF-related surgery (cohort 3). Validated, general and disease-specific patient-reported outcome data were collected using a 45-min IRB/EC-approved web-enabled questionnaire. The level of FI was evaluated using the Revised Faecal Incontinence Score (RFIS) (1–20 scale, 0 = no incontinence, 4-week recall period) and the impact of FI on QoL in patients who had experienced FI using the Fecal Incontinence Quality of Life (FIQL) (1–5 scale, 1 = lower QoL). Data were analysed using descriptive statistics. Results Of the 929 patients recruited (cohort 1, n = 620; cohort 2, n = 174; cohort 3, n = 135), 58–69% were male and 55–67% were aged 21–40 years across all cohorts. A significantly higher proportion of patients in cohort 3 than cohort 1 had severe Crohn’s disease as classified by a physician (18% vs 9%, respectively; p < 0.05). Overall, 47% of patients reported experiencing FI and completed both the RFIS and FIQL. Significantly higher proportions of patients in cohorts 2 and 3 had experienced FI than in cohort 1 (59% and 59% vs 40%, respectively; p < 0.05), and a significantly higher proportion were currently experiencing FI in cohort 3 than in cohorts 1 and 2 (69% vs 37% and 45%, respectively; p < 0.05). Mean RFIS scores were significantly higher (worse) in cohorts 2 and 3 than cohort 1 (9.5 [p < 0.05] and 10.6 [p < 0.001] vs 8.2, respectively). Patients in cohort 2 had significantly lower (worse) FIQL scores than those in cohort 1 across three FIQL domains (lifestyle [2.2 vs 2.4], depression/self-perception [2.1 vs 2.3], embarrassment [2.2 vs 2.4]; p < 0.05), whereas patients in cohort 3 only reported significantly lower FIQL scores compared with cohort 1 in the embarrassment domain (2.2 vs 2.4; p < 0.05). Conclusion In this study almost half of the patients experienced faecal incontinence. Among those who experienced faecal incontinence, patients with PAF experienced a significantly higher impact on their quality of life compared with patients without PAF.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
