Abstract

fetched live from OpenAlex

13 Background: According to USP 797 and the National Association of Pharmacy Regulatory Authorities standards, the Beyond Use Date (BUD) based on sterility for single-dose vials is 6 hours, after which the contents must be discarded. In Ontario, centres have traditionally based BUD on stability data, not sterility data. This change presents concern about potential drug waste so an analysis was done to estimate the financial impact to the 76 systemic treatment facilities in Ontario. Methods: Using an administrative database that records the daily total dose of drugs administered by facility, annual drug waste cost was calculated using daily dose administered, cost per milligram, and available vial size(s) for 26 publicly funded drugs. Two different methods were used to determine the amount of drug waste. Method 1 used the largest vial size matched to the closest amount of drug required. Method 2 used the optimal vial size mix, when there are multiple vial sizes, to minimize wastage across all configurations of vial size. Some assumptions made include: 1) each facility had access to all available vial sizes, and 2) single-dose vial contents were true to the stated quantity as per the manufacturer. Results: The 10 facilities with the highest waste estimates are summarized in the table. The total waste estimates for all facilities are $25,927,861 (method 1) and $12,945,353 (method 2). Waste estimates were also calculated by drug, with rituximab, bevacizumab and pemetrexed having the highest waste costs. These drugs are only available in vials with a large range in size (100 and 500 mg), but could waste more than drugs with more size options or less variance between sizes. Conclusions: Assigning a BUD based on 6 hour sterility standards will have significant financial implications to facilities in Ontario. Development of mitigation strategies should be explored to provide guidance to Ontario and other jurisdictions on how to curtail the budget impact.[Table: see text]

Not 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.
