Accurate mobility assessment of hospitalized older adults is necessary to aid nurses in planning and providing appropriate mobility support; however, nurses cite lack of resources and time limitations as barriers. Accelerometry enables a detailed objective measurement of predominant hospital mobility activities in the older adult population, such as percent time sitting, and the sit-to-stand (STS) transition. The current exploratory study examined the use of a novel, unobtrusive accelerometry technique to obtain postural and STS metrics on 27 older adults during their hospital stay. Total device wear time in the hospital was 96.2%. Participants spent 60.3% time lying, 20.3% time sitting, 5.3% time standing, and 2% time stepping during hospitalization, and, on average, completed the STS transition 20 times (SD = 13) per 24-hour period. There were no participant complaints about wearing the device. Our exploratory study shows accelerometry provides automated, continuous data and may support accurate nursing assessment of patient mobility. [Journal of Gerontological Nursing, 48(5), 35–41.]

有必要对住院老年人进行准确的行动能力评估，以帮助护士规划和提供适当的行动支持；然而，护士将缺乏资源和时间限制列为障碍。加速度测量法能够对老年人群中主要的医院移动活动进行详细的客观测量，例如就坐时间百分比和从坐到站 (STS) 的转换。目前的探索性研究检查了使用一种新颖的、不显眼的加速度测量技术来获取 27 名老年人住院期间的姿势和 STS 指标。在医院的总设备佩戴时间为 96.2%。参与者在住院期间花费了 60.3% 的躺卧时间、20.3% 的坐姿时间、5.3% 的站立时间和 2% 的步行时间，并且平均完成了 20 次 STS 转换（SD= 13) 每 24 小时。没有参与者抱怨佩戴该设备。我们的探索性研究表明，加速度计可提供自动化、连续的数据，并可能支持对患者活动能力的准确护理评估。[老年护理杂志，48（5），35-41。]
