Wearable devices generate signals detecting activity, sleep, and heart rate, all of which could enable detailed and near-continuous characterization of recovery following critical illness.
To determine the feasibility of using a wrist-worn personal fitness tracker among patients recovering from critical illness, we conducted a prospective observational study of a convenience sample of 50 stable ICU patients. We assessed device wearability, the extent of data capture, sensitivity and specificity for detecting heart rate excursions, and correlations with questionnaire-derived sleep quality measures.
Wearable devices were worn over a 24-h period, with excellent capture of data. While specificity for the detection of tachycardia was high (98.8%), sensitivity was low to moderate (69.5%). There was a moderate correlation between wearable-derived sleep duration and questionnaire-derived sleep quality ( = 0.33, = 0.03). Devices were well-tolerated and demonstrated no degradation in quality of data acquisition over time.
We found that wearable devices could be worn by patients recovering from critical illness and could generate useful data for the majority of patients with little adverse effect. Further development and study are needed to better define and enhance the role of wearables in the monitoring of post-ICU recovery.

可穿戴设备可生成检测活动、睡眠和心率的信号，所有这些都能够对危重症后的恢复情况进行详细且近乎连续的特征描述。
为了确定在危重症康复患者中使用腕戴式个人健身追踪器的可行性，我们对50名病情稳定的ICU患者的便利样本进行了一项前瞻性观察研究。我们评估了设备的可穿戴性、数据捕获程度、检测心率异常的敏感性和特异性，以及与问卷得出的睡眠质量测量值的相关性。
可穿戴设备佩戴了24小时，数据捕获情况良好。虽然检测心动过速的特异性很高（98.8%），但敏感性为低到中度（69.5%）。可穿戴设备得出的睡眠时间与问卷得出的睡眠质量之间存在中度相关性（r = 0.33，P = 0.03）。设备耐受性良好，且未显示随着时间推移数据采集质量有所下降。
我们发现，危重症康复患者可以佩戴可穿戴设备，并且对于大多数患者而言，该设备能够产生有用的数据，几乎没有不良影响。需要进一步开发和研究，以更好地定义和增强可穿戴设备在ICU后恢复监测中的作用。
