Transferring non-mobile patients from the ground to a stretcher represents one of the riskiest tasks for musculoskeletal disorders among emergency medical technicians-paramedics (EMT-Ps), but there is little information available on how they perform in real-life work situations. This study aimed to describe EMT-Ps' patterns of behavior observed from field data and highlight safe work operations. A secondary analysis was conducted on 27 videos collected during EMT-Ps' responses to live calls. Contextual variables (workspace and external assistance), operations during the preparation subtask (move patient or interfering objects and adjust stretcher's height and position), and movements and postures related to the transfer subtask were extracted from the videos. The results demonstrate that despite stratification based on similar contextual factors (equipment and limited workspace), EMT-Ps' behavior varied between interventions during the preparation and transfer subtasks. Several operations to adjust the patient-stretcher configuration before the lifting phase were carried out to facilitate patient transfer, but these were not always optimal from a safety perspective. Strategies such as fast loading (1 out of 4) and the use of external assistance (6 out of 15) were beneficial in certain circumstances. EMT-Ps demonstrated their ability to analyze the situation, organize accordingly, and adapt their behavior by applying these safety skills.
将不能自主活动的患者从地面转移至担架上，对于急救医疗技术员-护理人员（EMT-Ps）来说，是肌肉骨骼疾病风险最高的任务之一，但关于他们在实际工作中的操作情况，目前几乎没有相关信息。本研究旨在描述从现场数据中观察到的EMT-Ps的行为模式，并强调安全的工作操作。对EMT-Ps在应对实际呼叫期间收集的27段视频进行了二次分析。从视频中提取了情境变量（工作空间和外部协助）、准备子任务期间的操作（移动患者或干扰物体以及调整担架的高度和位置）以及与转移子任务相关的动作和姿势。结果表明，尽管根据相似的情境因素（设备和有限的工作空间）进行了分层，但EMT-Ps在准备和转移子任务期间的干预行为仍存在差异。在抬起阶段之前进行了几次调整患者-担架配置的操作，以方便患者转移，但从安全角度来看，这些操作并不总是最佳的。快速装载（4次中有1次）和使用外部协助（15次中有6次）等策略在某些情况下是有益的。EMT-Ps通过应用这些安全技能，展示了他们分析情况、相应组织并调整行为的能力。
