To describe the amount and patterns of ambulatory activity in hospitalized older adults over consecutive hospital days.
Observational cohort study.
University teaching hospital Acute Care for Elderly (ACE) unit.
Adults aged 65 and older (N = 239) who wore a step activity monitor during their hospital stay.
Total number of steps per 24-hour day. Mean daily steps were calculated based on number of days the step activity monitor was worn.
Mean age was 76.6 ± 7.6; 55.1% of participants were female. Patients took a mean number of 739.7 (interquartile range 89-1,014) steps per day during their hospital stay. Patients with shorter stays tended to ambulate more on the first complete day of hospitalization and had a markedly greater increase in mobility on the second day than patients with longer lengths of stay. There were no significant differences in mean daily steps according to illness severity or reason for admission.
Objective information on patient mobility can be collected for hospitalized older persons. Findings may increase understanding of the level of ambulation required to maintain functional status and promote recovery from acute illness.
描述连续住院日期间住院老年患者的门诊活动量和模式。
观察性队列研究。
大学教学医院急性老年护理（ACE）病房。
在住院期间佩戴计步器的年龄在 65 岁及以上的成年人（N=239）。
每 24 小时的步数。根据佩戴计步器的天数计算平均每日步数。
平均年龄为 76.6±7.6；55.1%的参与者为女性。患者在住院期间平均每天行走 739.7 步（四分位间距 89-1014）。住院时间较短的患者在住院的第一天活动量较大，与住院时间较长的患者相比，他们在第二天的活动量增加更为显著。疾病严重程度或入院原因与每日平均步数均无显著相关性。
可以为住院老年人收集有关患者活动能力的客观信息。研究结果可能会增加对维持功能状态和促进急性疾病康复所需的活动量的了解。
