Abstract
BACKGROUND: Delirium is an important problem in hospitalized cancer patients. The objective of this study was to determine whether exposure to corticosteroids, benzodiazepines, or opioids predicted delirium. METHODS: A prospective cohort study was conducted in an oncology/internal medicine population. Patients were assessed continuously for the presence of delirium until they were discharged by using the Nursing Delirium Screening Scale (Nu-DESC). Follow-up for outcome began after incident delirium. The primary outcome was the presence of a delirium event, which was defined as a Nu-DESC score >1. Strengths of associations of medications with delirium were expressed as odds ratios (ORs) in univariate and multivariate analyses. RESULTS: In total, 114 patients (1823 patient-days) met the inclusion criteria for the study. The mean follow-up from incident delirium was 16 days. The mean number of delirium events by patient was 6 (total number, 667 delirium events). Analysis by day on several occasions revealed significant associations between opioids and delirium. Corticosteroids and benzodiazepines were not associated significantly with an increased risk of delirium on any given day. Analysis by patient using generalized estimating equation (GEE) models showed an increased risk of delirium on any day of follow-up associated with opioid exposure in univariate analysis (OR of 1.70; P<.0001). The association remained significant after adjustment for corticosteroid, benzodiazepine, and antipsychotic exposure using GEE regressions (OR of 1.37; P=.0033). Truncating follow-up at 30 days did not affect the results (OR of 1.38; P<.032). CONCLUSIONS: Exposure to opioids during hospitalization was associated significantly with an increased longitudinal risk of delirium.

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 it
