目的:评价可穿戴监测设备用于术后患者早期活动和睡眠监测的准确性。方法:随机抽样健康志愿者20名，均参与睡眠和活动时间两种监测。选择本院消化道肿瘤切除术后患者89例，采用简单随机分组法，43例参与睡眠时长监测，46例参与活动时间监测。采用ePM/eP pod无线可穿戴监测系统记录活动和睡眠时间，同时分别人工记录活动时间和Fitbit手环记录睡眠时间，计算两种记录方式的差值。结果:健康志愿者或术后患者中，Fitbit手环和可穿戴监测系统监测的睡眠时间比较差异无统计学意义(n P>0.05)；健康志愿者Fitbit手环与可穿戴监测系统记录的睡眠时间呈正相关(n r＝0.937，n P<0.001)，术后患者Fitbit手环与可穿戴监测系统记录的睡眠时间呈正相关(n r＝ 0.984，n P0.05)，术后患者中，可穿戴监测系统记录的活动时间与人工记录时间比较差异有统计学意义(n P<0.05)；术后患者人工记录与可穿戴监测系统记录的活动时间呈正相关(n r＝0.973，n P0.05). The sleep duration recorded by Fitbit was positively correlated with the sleep duration recorded by the wearable system in healthy volunteers (n r=0.937, n P<0.001), and the sleep duration recorded by the Fitbit was positively correlated with the sleep duration recorded by the wearable system in postoperative patients (n r=0.984, n P0.05), and there was significant difference between motion duration recorded by the wearable system and that recorded manually in postoperative patients (n P<0.05). The manually recorded motion duration was positively correlated to the motion duration recorded by the wearable device (n r= 0.973, n P<0.001). The results of Bland-Altman analysis showed that the percentage of difference between the motion duration recorded manually and that recorded by the wearable system between 95% LOA was 100% in healthy volunteers, and the percentage of difference between 95% LOA was 96% in postoperative patients.n Conclusion:The wearable device can be used for postoperative sleep and activity monitoring in the patients, with higher accuracy.
