The objective of this time-motion study was to document the type and duration of activities performed by wheelchair suppliers during the provision of wheeled mobility and seating devices.
Researchers observed eight rehabilitation technology suppliers and four rehabilitation technicians over two weeks in two metropolitan areas.
Data were collected on 500 client interactions, resulting in 864 activities that were classified as complex rehabilitation technology (CRT) or standard wheeled mobility equipment (STD). Data indicate that the majority of the activities were relatively short (median = 0.25 hours) but the distribution of activity durations was highly skewed. A difference existed in activity time across device complexity (p = 0.039), with CRT-related activities averaging about 0.1 hours longer in duration than STD activities. When assessing mobility types independently, activity times across device complexity differed for manual and power wheelchair at p = 0.0001 and p = 0.086 levels, respectively. When activities were tabulated into daily episodes for each client, CRT manual wheelchair times were higher than STD (p = 0.003), whereas power wheelchair episode times showed no difference across device complexity (p = 0.245).
The results illustrate that the activities undertaken by suppliers during wheelchair provision vary widely and device complexity and device type impacts the types and duration of these activities. [Box: see text].
本次时间动作研究的目的是记录轮椅供应商在提供轮式移动和座椅装置过程中所执行活动的类型和持续时间。
研究人员在两个大都市地区对八家康复技术供应商和四名康复技术人员进行了为期两周的观察。
收集了500次客户互动的数据,产生了864项活动,这些活动被归类为复杂康复技术(CRT)或标准轮式移动设备(STD)。数据表明,大多数活动相对较短(中位数=0.25小时),但活动持续时间的分布高度偏态。不同设备复杂性的活动时间存在差异(p=0.039),与CRT相关的活动持续时间平均比STD活动长约0.1小时。在独立评估移动类型时,不同设备复杂性的活动时间在手动轮椅和电动轮椅上分别在p=0.0001和p=0.086水平上存在差异。当将活动按每个客户的每日事件列表时,CRT手动轮椅时间高于STD(p=0.003),而电动轮椅事件时间在不同设备复杂性之间没有差异(p=0.245)。
结果表明,供应商在提供轮椅过程中所进行的活动差异很大,设备复杂性和设备类型会影响这些活动的类型和持续时间。[方框:见正文]
