Inflammatory bowel disease--hospitalization.
Bibliographic record
Abstract
OBJECTIVES: This analysis examines trends in hospitalization for Crohn's disease and ulcerative colitis, the two main forms of inflammatory bowel disease (IBD). DATA SOURCES: Data are from the Hospital Morbidity Database for 1983/84 to 2000/01, and from the Health Person-Oriented Information Database for 1994/95 to 2000/01. ANALYTICAL TECHNIQUES: Sex- and age-specific rates were calculated for separations attributed to Crohn's disease and ulcerative colitis. Rates and hospital days were also calculated for hospitalizations in which IBD was among the first five diagnostic codes on a patient's discharge abstract. The frequency of rehospitalization was examined. MAIN RESULTS: From the early 1980s to the mid-1990s, annual rates of hospitalization for Crohn's disease and ulcerative colitis rose slightly, but have since levelled off. Hospitalization rates for both conditions are highest among people in their twenties. The average length of stay for patients with either disease fell from about 2 weeks in 1983/84 to 9 or 10 days in 2000/01. More than a quarter of patients hospitalized for Crohn's disease and over 20% of those with ulcerative colitis were readmitted within the same year.

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.
