Coronary bypass grafting in South Thames: The correlation between clinical scores and waiting times
Bibliographic record
Abstract
To determine waiting times before surgery and their correlation with clinical need, we examined the files of 1049 patients on the waiting list for coronary bypass grafting in 1996. The total waiting time to bypass grafting was 279 (SD 209) days (range 1-1579 days). Waiting time to specialist consultation was 36 (SD 43) days, and time on the waiting list for coronary angiography was 85 (SD 89) days. The mean time on the surgical waiting list was 133 (SD 134) days. Patients with a Birmingham clinical score below 10 waited between 27 and 879 days, and patients with scores above 35 waited between 3 and 282 days. Total waiting time was weakly associated with the priority score (Pearson correlation = -0.51). We conclude that waiting times were long with wide variation at every stage between referral and coronary bypass grafting. There was little correlation between clinical scores and waiting times.

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.
