Abstract
BACKGROUND: The experiences of the development of a provincial program to promote blood conservation are herein reported. STUDY DESIGN AND METHODS: Transfusion coordinators were placed in 23 Ontario hospitals. Anonymized laboratory and clinical information was collected in a defined number of all consecutive patients admitted for three designated procedures: knee arthroplasty, abdominal aortic aneurysm (AAA), and coronary artery bypass graft (CABG) surgery (n approximately 1100, 300, and 300 at each time period, respectively). RESULTS: Considerable interinstitutional variation was observed in the proportion of patients who received transfusions. At 12 months, and over the 24-month period of the project, most hospitals demonstrated decreased use of allogeneic blood; at 12 months an approximate 24 percent reduction in patients undergoing knee surgery, 14 percent in AAA, and 23 percent in CABG was obtained. In addition, patients who received transfusions received less allogeneic blood. Patients who did not receive allogeneic transfusions had lower postoperative infection rates (p < 0.05) and length of stay (p < 0.0001); allogeneic transfusion was an independent predictor of increased length of stay. The main blood conservation measures employed during this time were education, preoperative autologous donation, erythropoietin, and cell salvage. CONCLUSION: The implementation of a provincial network of transfusion coordinators was feasible and allogeneic transfusion rates declined over the period the program has been in place.

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
