The cost of transfusing a unit of red blood cells: a costing model for Canadian hospital use
Bibliographic record
Abstract
Background No direct and thorough accounting of costs related to packed red blood cells ( PRBC s) has occurred in recent Canadian history. Our study sought to determine the cost accrued for a unit of PRBC within a Canadian hospital related to the inventory management, storage, testing, issuing and administration of the product. Methods An eight‐step costing model was developed to capture associated costs from the time of receipt at the hospital to the time of transfusion to a patient. Personnel, consumables and capital equipment costs within each step of the model were assessed using activity‐based accounting methods and German cost accounting principles. Results Based on 10,475 units, total in‐hospital cost per unit of PRBC was $243·10. Personnel, consumables and capital costs contributed 77·54%, 19·86% and 2·60% to this cost, respectively. Conclusion This study's in‐hospital costs of $243·10 summed with the $423·00 acquisition costs per unit PRBC from the blood supplier place the complete societal costs of one unit PRBC s at $666·10. This value is comparable, but lower than the majority of studies in the United States and Europe examining the societal costs of PRBC s.

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.
