The purpose of this study was to examine: a) how long and how frequently older hospitalized patients spend upright; b) whether duration and frequency of upright time change by time of the day, the day of the week, and during hospitalization; and c) whether these relationships differ based on the mobility level of patients at admission.
This prospective cohort study included 111 patients (82.2 ± 8 years old, 52% female) from the Emergency Department and a Geriatric Assessment Unit who were at least 60 years old and had an anticipated length of stay of at least three days. The main outcomes were accelerometer-measured total upright time and number of bouts of upright time during awake hours.
Patients were upright 15.9 times/day (interquartile range (IQR): 8.4-27.4) for a total of 54.2 min/day (IQR: 17.8-88.9) during awake hours. Time of day and day of week had little impact on the outcomes. Patients who walked independently at admission had 151.5 min (95% CI: 87.7-215.3) of upright time on hospital day 1 and experienced a decline of 4.5 min/day (-7.2 to -1.8). Those who needed personal mobility assistance or were bedridden had 29.5 min (-38.5-97.4) and 25 min (-48.3-100.3) of upright time on day 1, and demonstrated an increase of 3.6 (1.3-5.9) and 2.4 (0.05-4.5) min/day, respectively.
Hospitalized older adults spend only 6% of their awake hours upright while in hospital. Patients who can walk independently are more active but experience a decline in their upright time during hospitalization.
本研究旨在检验：a）老年住院患者每天直立的时间和频率；b）每天的时间、一周中的天数以及住院期间直立时间的持续时间和频率是否发生变化；c）这些关系是否因患者入院时的活动能力而异。
这项前瞻性队列研究纳入了 111 名来自急诊部和老年评估病房的患者（82.2±8 岁，52%为女性），他们年龄至少为 60 岁，预计住院时间至少为 3 天。主要结局是通过加速度计测量的总直立时间和清醒时间内的直立时间。
患者每天直立 15.9 次（四分位距：8.4-27.4），清醒时间内总直立时间为 54.2 分钟（四分位距：17.8-88.9）。时间和星期几对结果影响不大。入院时能独立行走的患者在入院第 1 天有 151.5 分钟（95%可信区间：87.7-215.3）的直立时间，每天减少 4.5 分钟（-7.2 至-1.8）。需要个人移动辅助或卧床不起的患者在第 1 天分别有 29.5 分钟（-38.5-97.4）和 25 分钟（-48.3-100.3）的直立时间，每天分别增加 3.6 分钟（1.3-5.9）和 2.4 分钟（0.05-4.5）。
住院的老年患者在住院期间清醒时只有 6%的时间是直立的。能够独立行走的患者更活跃，但在住院期间直立时间会减少。
