Reliability and validity testing of automated scoring in obstructive sleep apnea diagnosis with the Embletta X100

摘要: Objectives/Hypothesis To verify the reliability and validity of automated scoring compare it to that manual for diagnosing obstructive sleep apnea using an Embletta X100 level 2 portable device. Study Design Retrospective study. Methods A total 116 patients with suspected who had successfully received polysomnography were examined. All data analyzed by methods. Manual was performed according revised American Academy Sleep Medicine 2012 criteria. Automated automatic algorithm, which updated parameters evaluated statistically correlation analysis paired t tests. Results The apnea-hypopnea index moderately correlated (r = 0.76, P < .001). However, there poor agreement (Bland-Altman plot, κ = 0.34, 0.33, 0.26; cutoff value = 5, 15, 30), generally excessively underestimated based on diagnostic disagreement Furthermore, severity (Kendall tau-b = 0.62) between lacked good concordance. Conclusions Automated related results. tended underestimate compared scoring. Thus, a expert is essential diagnosis X100. Level Evidence 4. Laryngoscope, 125:493–497, 2015
