Magnusdottir S, Hilmisson H, Sveinsdottir E. Sleep Disorder Screening: Integration of Subjective and Objective Measures. SM J Sleep Disord 2017; 3(2): 1014 https://smjournals.com/sleep-disorders/download.php?file=fulltext/smjsd-v3-1014.pdf
Comparing the output of two subjective self-evaluating sleep questionnaires commonly used in adult populations at-risk for sleep disorders, focusing on sleepiness and insomnia symptoms, to automated CardioPulmonary Coupling (CPC) analysis of electrocardiography (ECG) data collected during sleep, to measure sleep quality.
Sleep questionnaires have low sensitivity, specificity and agreement when compared to objective sleep measures.
The need to add an objective measure of sleep physiology and pathology to subjective patient self-evaluation of sleep quality when screening for sleep disorders can be solved with this simple, FDA-cleared method to evaluate sleep and sleep disorders.
