After transitioning from an intensive care unit (ICU), hospitalized older adults are inactive, which may affect discharge outcomes. We examined trends between post-ICU hourly activity counts and discharge disposition among hospitalized older ICU survivors.
A prospective, exploratory research design was used in this study.
We enrolled older ICU survivors within 24-48 hours of ICU discharge. Actigraphy measured post-ICU hourly activity counts (0:00 a.m.-23:59 p.m.). Chart review provided discharge disposition. Analyses were conducted to illustrate trends between post-ICU hourly activity counts and discharge disposition.
Mean hourly activity was about 2,233 ± 569 counts/hour. Graphs revealed trends between hourly activity counts and discharge disposition. Participants with lower post-ICU activity counts, especially during daytime hours, tended to be discharged to a care facility.
Future nursing research should determine whether post-ICU inactivity during hospitalization is a modifiable risk factor for worse discharge outcomes.
Activity could be a prognostic indicator of discharge disposition for older ICU survivors.
从重症监护病房（ICU）出院后，住院老年患者活动量减少，这可能会影响出院结局。我们研究了 ICU 出院后每小时活动计数与出院去向之间的趋势，以了解住院老年 ICU 幸存者的情况。
本研究采用前瞻性、探索性研究设计。
我们在 ICU 出院后 24-48 小时内招募了老年 ICU 幸存者。活动记录仪测量 ICU 后每小时活动计数（从凌晨 0:00 到晚上 11:59）。病历回顾提供了出院去向。分析旨在说明 ICU 后每小时活动计数与出院去向之间的趋势。
平均每小时活动量约为 2233±569 次/小时。图表显示了每小时活动计数与出院去向之间的趋势。活动量较低的 ICU 后患者，尤其是在白天，往往会被送往护理机构。
未来的护理研究应确定住院期间 ICU 后无活动是否是出院结局较差的可改变风险因素。
活动量可能是老年 ICU 幸存者出院去向的预后指标。
