ABSTRACT Background and Objective: In July 2000, the Pharmaceuticals and Therapeutics Committee at a 452-bed teaching hospital recommended discontinuation of its 7-day automatic stop order (ASO) policy, which applied to all drugs used in the hospital. Retrospective audits of duration of antimicrobial therapy were performed just before discontinuation of the 7-day ASO (ASO-7d) and 1 year after the ASO was removed (ASO-none). Because the duration of antimicrobial therapy increased over this 1-year period, a 5-day ASO was instituted (ASO-5d). Six months later, another audit was performed. The purpose of this study was to determine the influence of discontinuing and subsequently re-establishing an ASO on the duration of antimicrobial therapy. Methods: Antimicrobial orders were categorized on the basis of duration of therapy: 1 to 8 days (standard), 9 to 20 days (intermediate), and more than 20 days (long). The percentages of orders continuing on each consecutive day after initiation of therapy in the 3 periods (ASO-7d, ASO-none, and ASO-5d) were compared. Statistical analysis consisted of the Cochran–Armitage trend test for ordinal data, with a Bonferroni correction for multiple comparisons. Results: The percentage of orders categorized as standard therapy was 88.2% in the ASO-7d audit period, 82.8% in the ASO-none audit period, and 84.4% in the ASO-5d audit period. The percentage of orders categorized as intermediate in duration was 10.9% in the ASO-7d audit period, 15.0% in the ASO-none audit period, and 14.2% in the ASO-5d audit period. The percentage of orders categorized as long duration was 0.9% in the ASO-7d audit period, 2.2% in the ASO-none audit period, and 1.4% in the ASO-5d audit period. The trends for each of the 3 durations of therapy (1–8 days, 9–20 days, and more than 20 days) were significantly different from one another. Conclusions: The percentage of orders that were continued for 8 days or less (standard therapy) was greater during the ASO-7d audit period than in the ASO-none and ASO-5d audit period. Conversely, a smaller percentage of orders in the ASO-7d audit period were of intermediate or long duration. This suggests that a 7-day ASO is the most beneficial in terms of controlling duration of antimicrobial therapy. RESUME Historique : En juillet 2000, le Comite de pharmacologie d’un hopital d’enseignement de 452 lits a recommande l’abandon de sa politique d’ordonnance avec duree de validite (ODV) de 7 jours, qui s’appliquait a tous les medicaments utilises dans cet hopital. Des verifications retrospectives de la duree des traitements antimicrobiens ont ete realisees juste avant l’abandon de l’ODV de 7 jours (ODV-7j) et une annee apres l’abandon effectif de l’ODV (ODV-nil). Parce que la duree des traitements antimicrobiens s’est allongee durant cette periode d’une annee, une ODV de 5 jours a ete mise en oeuvre (ODV-5j). Six mois plus tard, on a effectue une autre verification. Le but de cette etude etait de determiner l’influence de l’abandon puis de la reintroduction subsequente d’une ODV sur la duree des traitements antimicrobiens. Methodes : Les ordonnances d’antimicrobiens ont ete divisees en trois groupes, sur la base de la duree de la therapie : de 1 a 8 jours (standard), de 9 a 20 jours (intermediaire), et plus de 20 jours (prolongee). On a compare le pourcentage d’ordonnances toujours en vigueur a chaque journee consecutive durant les trois periodes (ODV-7j, ODV-nil, ODV-5j). Le test des tendances de Cochran-Armitage pour les donnees ordinales, avec une correction de Bonferroni pour les comparaisons multiples, a ete utilise comme analyse statistique. Resultats : Le taux d’ordonnances tombant dans la categorie standard etait de 88,2 % durant la periode ODV-7j, de 82,8 % durant la periode ODV-nil, et de 84,4 % durant la periode ODV-5j. Celui tombant dans la categorie intermediaire etait de 10,9 % durant la periode ODV-7j, de 15,0 % durant la periode ODV-nil, et de 14,2 % durant la periode ODV-5j. Celui tombant dans la categorie prolongee etait de 0,9 % durant la periode ODV-7j, de 2,2 % durant la periode ODV-nil, et de 1,4 % durant la periode ODV-5j. Les tendances pour chacune des trois categories de duree de therapie (1–8 jours, 9–20 jours, et plus de 20 jours) etaient significativement differentes d’une a l’autre. Conclusions : Le taux d’ordonnances en vigueur durant huit jours ou moins (therapie standard) etait superieur dans le groupe ODV-7j que dans les groupes ODV-nil et ODV-5j. Inversement, le taux d’ordonnances en vigueur pour une duree intermediaire et prolongee etait plus faible durant la periode ODV-7j. Ces donnees portent a croire qu’une validite d’ordonnance de 7 jours est la plus benefique pour controler la duree du traitement antimicrobien.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
