To compare the accuracy of portable monitoring for obstructive sleep apnea (OSA) with polysomnography (PSG) in commercial drivers.
A consecutive case series of drivers were screened for OSA using recent validated consensus conference criteria at a single occupational medicine clinic; those screening positive were tested with a portable OSA screening device while awaiting PSG.
Three hundred forty-six drivers were screened and 34 completed PSG and portable monitoring. Comparing the portable device to PSG at a definition of OSA as an apnea hypopnea index (AHI) >or=15, positive predictive value is 0.64 with a 0.87 negative predictive value. Positive likelihood ratio is 4.20. Linear regression model found statistically significant relationship (P = 0.0004) between the portable device and PSG AHI values.
Although not perfect, portable monitoring may be useful in further stratifying risk in drivers who have a high probability of having OSA.
比较便携式监测在商业司机阻塞性睡眠呼吸暂停（OSA）与多导睡眠图（PSG）中的准确性。
在一家职业医学诊所，采用最近验证的共识会议标准对司机进行 OSA 的连续病例系列筛查；对筛查阳性者进行便携式 OSA 筛查装置检测，同时等待 PSG。
对 346 名司机进行了筛查，34 名完成了 PSG 和便携式监测。将便携式设备与 PSG 进行比较，当 OSA 的定义为呼吸暂停低通气指数（AHI）≥15 时，阳性预测值为 0.64，阴性预测值为 0.87。阳性似然比为 4.20。线性回归模型发现便携式设备和 PSG AHI 值之间存在统计学显著关系（P = 0.0004）。
尽管不完美，但便携式监测可能有助于进一步分层风险，对那些极有可能患有 OSA 的司机进行分层。
