To evaluate unattended full polysomnography (PSG) recorded in the home by the DigiTrace Home Sleep System (DHSS) and to assess the ability to acquire, store and analyze polysomnographic data using the DHSS compared to standard paper PSG.
Part 1 used a prospective, cross-over design. Part 2 consisted of a prospective concurrent collection of polysomnographic data.
Sleep Disorders Center in a university medical center.
All adult patients who required standard clinical PSG as part of their clinical evaluation, regardless of suspected diagnosis, except patients requiring video recording for abnormal behaviors.
The DHSS is a digital recording system with miniature preamplifiers and the capacity to record 18 channels of polysomnographic data, including 4 channels of EEG (C3-A2, C4-A1, C3-O1 and C4-O2), right and left EOG, two channels of chin EMG, ECG naso-oral airflow, respiratory effort (piezo crystal thoracic and abdominal belts and bilateral interacostal EMG), snore microphone, bilateral anterior tibialis EMG, and body-position sensor. In part 1,77 DHSS home recordings were evaluated. No recordings were lost due to equipment failure and each parameter was scorable in greater than 95% of all epochs. Most of the subjective assessments by questionnaire following each study revealed no difference between the two testing situations. However, patients reported more sleep time and a better overall test experience in the lab. Assessments of sleep quality and morning alertness compared to usual were rated higher in the lab. After completing both studies, more patients preferred the lab study (p < .01), mostly because of minor inconveniences and apprehension regarding acquisition of data during the home study. There was no difference in the assessment of which test most accurately represented their sleep. In Part 2, the DHSS recorded concurrently with paper PSG in the laboratory in 16 patients. The results show no significant differences for any parameter and strong positive correlations for all parameters.
Using the DHSS, unattended full PSG can be performed in the home with reliable and high quality recordings. Full PSG can be extended to a larger patient population, because it is no longer limited by the number of beds, and there is a reduction in cost due to elimination of overnight staff and facility cost.
评估由DigiTrace家庭睡眠系统（DHSS）在家中记录的无人值守全夜多导睡眠图（PSG），并评估与标准纸质PSG相比，使用DHSS采集、存储和分析多导睡眠图数据的能力。
第1部分采用前瞻性交叉设计。第2部分包括前瞻性同步收集多导睡眠图数据。
大学医学中心的睡眠障碍中心。
所有需要标准临床PSG作为临床评估一部分的成年患者，无论疑似诊断如何，但需要对异常行为进行视频记录的患者除外。
DHSS是一种数字记录系统，带有微型前置放大器，能够记录18通道的多导睡眠图数据，包括4通道脑电图（C3-A2、C4-A1、C3-O1和C4-O2）、左右眼电图、两通道颏肌肌电图、心电图、鼻口气流、呼吸努力（压电晶体胸腹部带和双侧肋间肌肌电图）、鼾声麦克风、双侧胫前肌肌电图和体位传感器。在第1部分中，评估了77份DHSS家庭记录。没有记录因设备故障丢失，并且每个参数在所有时段中超过95%均可评分。每项研究后通过问卷调查进行的大多数主观评估显示，两种测试情况之间没有差异。然而，患者报告在实验室中的睡眠时间更长，总体测试体验更好。与平常相比，实验室中对睡眠质量和早晨警觉性的评估得分更高。完成两项研究后，更多患者更喜欢实验室研究（p <.01），主要是因为在家中研究期间采集数据存在一些小不便和担忧。在评估哪种测试最准确地反映他们的睡眠方面没有差异。在第2部分中，DHSS在实验室中与纸质PSG同时记录了16例患者的数据。结果显示，任何参数均无显著差异，所有参数均呈强正相关。
使用DHSS，可以在家中进行无人值守的全夜PSG记录，记录可靠且质量高。全夜PSG可以扩展到更多患者群体，因为它不再受床位数量限制，并且由于无需夜间工作人员和设施成本，成本有所降低。
