Abstract
OBJECTIVE: An ideal emergency department (ED) triage system accurately prioritises patients on the basis of the urgency of interventions required to avoid under- or over-triage. The objective of this study was to develop and validate a five-level Taiwan triage and acuity scale (TTAS) with an electronic decision support tool. METHODS: This prospective, multicentre, observational study included 10533 patients triaged at 11 academic medical centres, 18 regional and four district hospitals. Adult patients presenting to the ED were independently triaged by the duty triage nurse in the usual way and trained research nurses using TTAS with a computerised decision support system. Weighted κ statistics were used to assess the reproducibility. Hospitalisation, length of stay, and medical resource consumption were analysed by TTAS acuity levels. RESULTS: Most cases were stratified into levels 2 to 3 by the existing four-level triage system, whereas the TTAS stratified most patients to levels 3 (41.4%) and 4 (25.0%), and only a small number to level 1 (3.9%) (resuscitation; most urgent). Weighted κ for TTAS assignment was 0.87 (95% CI 0.85 to 0.89). The decrease in mean medical resource consumption and hospitalisation rate was statistically significant with each decrease in the TTAS triage acuity level. The length of stay also decreased significantly as the TTAS level acuity fell from levels 2 to 5. CONCLUSIONS: The TTAS was found to be a reliable triage system that accurately prioritises the treatment needed to avoid overtriage, more efficiently deploying the appropriate resources to ED patients.

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
