Efficacité de 6 scénarios de décontamination de bras de fauteuils contaminés volontairement au cyclophosphamide
Bibliographic record
Abstract
RÉSUMÉ Contexte : Les bras de fauteuils en clinique externe d’oncologie sont fréquemment contaminés au cyclophosphamide. Objectif : Évaluer l’efficacité de scénarios de décontamination. Méthodologie : Il s’agit d’une étude descriptive de type simulation de 6 scénarios de décontamination d’une surface de tissu en silicone contaminée avec 10 µg de cyclophosphamide. Les produits de décontamination testés (ammonium quaternaire, peroxyde d’hydrogène 0,5 %, détergent 0,005 % et hypochlorite de sodium 0,5 %) ont été utilisés avec des lingettes de microfibres. La contamination résiduelle a été mesurée à l’aide d’un système de chromatographie liquide ultra- performante et de spectrométrie de masse en tandem, avec des limites de détection et de quantification du cyclophosphamide identiques (0,0006 ng/cm2). Résultats : Parmi les 59 échantillons, 3 blancs étaient négatifs, 5 ont permis la mesure du taux de récupération (93,7 ± 4,6 % [écart-type]) et 51 étaient expérimentaux. L’efficacité moyenne des agents était supérieure ou égale à 99,79 %. Quel que soit l’agent utilisé, l’efficacité était de 99,30 ± 1,20 % après un seul nettoyage (n = 18), 99,90 ± 0,15 % après 2 (n = 18) et 99,95 ± 0,06 % après 3 (n = 15). Conclusions : Six scénarios de décontamination se sont avérés efficaces. La répétition du nettoyage a augmenté de façon marginale l’efficacité de la décontamination.

Methods: This was a descriptive simulation-type study of 6 decontamination scenarios of a silicone fabric surface contaminated with 10 µg of cyclophosphamide. The decontamination products tested (quaternary ammonium, 0.5% hydrogen peroxide, 0.005% detergent, and sodium hypochlorite 0.5%) were applied with microfibre wipes. Residual contamination was measured using an ultra-performance liquid chromatography-tandem mass spectrometry system with identical cyclophosphamide detection and quantification limits (0.0006 ng/cm2). Results: Among the 59 samples, 3 blanks were negative, 5 allowed measurement of the recovery rate (93.7% [standard deviation 4.6%]), and 51 were experimental. The average efficiency of the agents was greater than or equal to 99.79%. Regardless of the agent used, effectiveness was 99.30% (SD 1.20%) after 1 cleanse (n = 18), 99.90% (SD 0.15%) after 2 cleanses (n = 18), and 99.95% (SD 0.06%) after 3 cleanses (n = 15). Conclusion: The 6 decontamination scenarios were effective. Repeated cleaning marginally increased the effectiveness of decontamination. Key words: cyclophosphamide, decontamination, simulation

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.
