Estimating the impact on the inventory of implementing pathogen‐reduced platelets in Canada
Bibliographic record
Abstract
BACKGROUND: Pathogen reduction (PR) technology will be implemented in pooled platelets in Canada. It is anticipated that PR platelets will be licensed in Canada for a maximum shelf life of 5 days, while non-treated apheresis platelet products will continue to be licensed for 7 days. STUDY DESIGN AND METHODS: This study evaluates the impact on inventory, wastage, and shortages of implementing PR platelets. A custom-built simulation model was used to represent a regional distribution network. Experiments with the model were used to estimate product wastage and shortages when a 5-day PR pooled platelet product is introduced alongside a 7-day apheresis platelet product. RESULTS: Pooled platelet waste and shortages both increase as pooled shelf life decreases. Apheresis platelets, however, show a different response: While shortages of apheresis platelets increase as the shelf life of pooled units decreases, apheresis waste declines as pooled shelf life decreases. CONCLUSION: Additional platelet collections will be necessary to accommodate the shorter PR platelet shelf life and to cover increased patient transfusion needs due to a lower platelet yield in PR units. Increases of 9% for pooled units and 6% for apheresis units beyond expected demand, were found to be sufficient to ensure a non-inferior level of customer service while minimizing waste.

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.
