目的：检查来自不同睡眠实验室的多导睡眠图技术人员在多导睡眠图评分方面的差异性。背景：多导睡眠图是诊断阻塞性睡眠呼吸暂停低通气综合征的金标准。睡眠阶段和呼吸事件有评分标准。我们试图确定如何不同的技术人员将评分相同的测试，使用他们的实验室的criterions.Methods：11个技术人员在9个不同的睡眠实验室，使用牛津Medilog SAC（c）系统评分11睡眠研究在医学大学的南卡罗来纳州睡眠障碍实验室利用各自的实验室的评分规则。所有睡眠检查均用于评估阻塞性睡眠呼吸暂停低通气综合征（OSAHS）。评分的研究返回和分析variability.Results：显着的变异性是存在于睡眠和呼吸事件的评分与呼吸事件评分表现出更多的变异性。在四项研究中，基于呼吸暂停低通气指数（AHI）的诊断从无到中度OSAHS不等，这取决于技术人员评分的研究，并在一项研究中的诊断从无到重度OSAHS.Conclusions：临床医生应该知道，有巨大的变化之间的多导睡眠图技术人员关于多导睡眠图的评分。这些差异可能是由于用于对事件进行评分的不同规则以及技术人员对规则的解释的差异。出版社：Elsevier Science B.V.
Objective: Examine the variability of polysomnography technologists from different sleep laboratories regarding scoring of polysomnograms.Background: Polysomnography is the gold standard to diagnose obstructive sleep apnea-hypopnea syndrome. There are criteria to score sleep stages and respiratory events. We sought to determine how different technologists would score the same tests using their laboratory's criteria.Methods: Eleven technologists in nine different sleep laboratories which used the Oxford Medilog SAC (c) system scored eleven sleep studies performed in the Medical University of South Carolina Sleep Disorders Laboratory utilizing their respective laboratory's scoring rules. All sleep studies were performed for evaluation of obstructive sleep apnea-hypopnea syndrome (OSAHS). The scored studies were returned and analyzed for variability.Results: Significant variability was present in scoring of both sleep and respiratory events with more variability demonstrated in respiratory event scoring. In four of the studies, diagnoses based on apnea-hypopnea indices (AHI) varied from none to moderate OSAHS depending on which technologist scored the study and in one study the diagnosis varied from none to severe OSAHS.Conclusions: Clinicians should be aware that there is tremendous variability among polysomnography technologists regarding the scoring of polysomnograms. These differences are likely due to different rules used to score events as well as differences in the technologist's interpretation of the rules. Published by Elsevier Science B.V.
