Analyse du besoin des ambulanciers dans un processus de conception centré sur les utilisateurs
Bibliographic record
Abstract
Au Québec, les services d’ambulance font face à des risques élevés de maladies professionnelles et d’accidents du travail. Le déplacement de bénéficiaires dans les escaliers avec une civière-chaise (CC) est l’une des tâches les plus exigeantes, contribuant fortement aux troubles musculosquelettiques (TMS) chez les techniciens ambulanciers paramédics (TAP). Pour réduire ces troubles, un nouveau prototype de CC semble nécessaire. Dans un projet interdisciplinaire, l’ergonomie élargit le cadre d’analyse et met en lumière les problématiques pour la conception d’un prototype. Des observations ouvertes pendant huit quarts de travail avec six TAP et trois transporteurs interhospitaliers, ainsi qu’une analyse secondaire de 81 entrevues ont été menées auprès de 50 TAP (11 femmes, 39 hommes) dans les grandes agglomérations québécoises, et confirment les constats des services préhospitaliers d’urgence partenaires du projet : les CC actuelles ne s’adaptent ni à tous les utilisateurs, ni aux différents types d’escaliers, ni à la complexité croissante de l’activité de soins. Ces limites renforcent l’urgence de repenser cet équipement clé. Abstract In Quebec, ambulance services face high risks of occupational diseases and work-related injuries. Transporting patients on staircases using a stair chair (SC) is one of the most demanding tasks and a major contributor to musculoskeletal disorders among paramedics. To reduce these issues, a new SC prototype appears necessary. In an interdisciplinary project, ergonomics broadens the analytical framework and highlights the issues involved in designing a prototype. Observations over eight shifts with six paramedics and three inter-hospital transporters, as well as a secondary analysis of 81 interviews conducted with 50 paramedics (11 women, 39 men) in major Quebec cities, confirm the findings of the project's prehospital emergency medical service partners: current SC are not adapted to all users, nor to the different types of staircases, nor to the increasing complexity of care activities. These limitations make it more urgent to rethink this key piece of equipment.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
