Abstract

Introduction

The aims of this study were to: describe post-ICU daytime sleep and activity among older ICU survivors within 24-48 hours post-ICU discharge, and to examine differences in post-ICU daytime sleep and activity by prospective acuity of discharge disposition at time of hospital discharge.

Methods

Within 24-48 hours of ICU discharge, we enrolled 30 ICU survivors who were at least 65 years old, functionally independent prior to hospitalization, and mechanically ventilated while in ICU. Actigraphy was used to estimate daytime total sleep time (TST, hours) and daytime activity (mean activity counts/minute) for one daytime period (06:00 AM to 22:00 PM) within 24-48 hours post-ICU discharge. Independent samples t-tests examined differences in mean daytime TST and daytime activity counts, between subjects who were discharged home versus those who were discharged to a facility (inpatient rehabilitation facility, skilled nursing facility, or long-term acute care hospital).

Results

The mean age was 71.37 ± 5.35 years; 63.3% were male and 76.7% were White non-Hispanic/Latino. The mean daytime TST was 7.61 ± 4.31 hours; the mean daytime activity count was 41.2 ± 28.24 counts/minute. Subjects who were discharged to a facility (8.88 ± 3.69 hours) slept significantly longer than those discharged to home (5.54 ± 4.21 hours; t(26) = 2.083, p = .047). Additionally, subjects who were discharged to a facility (32.96 ± 24.26 counts/minute) were significantly less active during the daytime than those discharged to home (54.42 ± 29.30 counts/minute; t(25) = -2.157, p = .041).

Conclusion

Older ICU survivors who were ultimately discharged to a facility slept significantly longer and were less active during the daytime hours immediately following transition out of ICU, compared to subjects who were discharged home. Intervention studies should investigate whether increasing daytime activity while promoting nighttime sleep consolidation following transfer out of ICU improves discharge outcomes.

1040年ICU后白天睡眠和活动影响医院老年ICU幸存者的出院结果

摘要

介绍

这项研究的目的是：描述ICU出院后24-48小时内老年ICU幸存者中ICU后的日间睡眠和活动，并通过当时的出院前瞻性敏锐度检查ICU后日间睡眠和活动的差异。出院。

方法

在ICU出院后的24-48小时内，我们招募了30名ICU幸存者，这些幸存者至少65岁，住院前功能独立，并且在ICU中进行了机械通气。在ICU出院后的24天（一天中，上午06:00至下午22:00）使用活动记录仪估算白天的总睡眠时间（TST，小时）和白天活动（平均活动计数/分钟）。独立样本t检验检验了出院对象与出院设施（住院康复设施，熟练护理设施或长期急性护理医院）之间的平均每日TST和白天活动计数的差异。

结果

平均年龄为71.37±5.35岁；男性为63.3％，非西班牙裔/拉丁美洲裔为76.7％。白天的平均TST为7.61±4.31小时；白天的平均活动计数为41.2±28.24个计数/分钟。出院的受试者（8.88±3.69小时）的睡眠时间比出院的受试者（5.54±4.21小时； t（26）= 2.083，p = .047）更长。此外，出院的受试者（32.96±24.26计数/分钟）白天的活跃度明显低于出院的受试者（54.42±29.30计数/分钟； t（25）= -2.157，p = .041） 。

结论

与出院的受试者相比，最终出院到设施中的老年ICU幸存者的睡眠时间长得多，并且在离开ICU后的白天白天的活跃度较低。干预研究应调查在转移出ICU后增加白天活动，同时促进夜间睡眠巩固是否能改善出院结果。
