Transporting patients in beds and stretchers throughout hospitals is a significant manual handling concern for transport teams, nurses, and nursing aides. The objective of this study was to evaluate a power-drive intervention when pushing beds and stretchers with different weight patients. Twelve participants were part of a laboratory simulation where beds and stretchers were pushed down a straight away, around a corner, down a ramp, and up a ramp with and without utilization of the power-drive feature. Peak three-dimensional spine loads were estimated during the trials. In all, power-drive reduced the three-dimensional spine loads by 8%-21% as compared to the manual pushing of the beds and stretchers. Larger reductions were found for the tasks performed with the bed as opposed to the stretcher. The inexperience of the participants may have reduced the benefit of the power-drive as they appeared to not use it to the full extent. To minimize the loads being placed on healthcare providers' spines and reduce the potential for injury hospitals should implement power-drive technologies on beds and stretchers.
在医院内用病床和担架运送患者，是运输团队、护士和护理助理面临的一项重大体力搬运问题。本研究的目的是评估在推送载有不同体重患者的病床和担架时，动力驱动干预措施的效果。12名参与者参与了一项实验室模拟实验，实验内容是在使用和不使用动力驱动功能的情况下，将病床和担架推过直线通道、绕过拐角、推下斜坡以及推上斜坡。在试验过程中估算了三维脊柱负荷的峰值。总体而言，与手动推送病床和担架相比，动力驱动使三维脊柱负荷降低了8%-21%。与担架相比，使用病床执行任务时负荷降低幅度更大。参与者缺乏经验，可能没有充分利用动力驱动功能，从而降低了其效果。为了尽量减少施加在医护人员脊柱上的负荷，并降低受伤风险，医院应在病床和担架上采用动力驱动技术。
