Is the Sleep Perception of Obstructive Sleep Apnea Patients Reliable?

Abstract

Aim: The aim of this study, is to evaluate the consistency with the polysomnography (PSG) data of the patients and the data reported by the patients themselves after PSG examination in the morning.Material and Methods: One hundred and thirty-four consecutive individuals who were admitted to the Chest Disease Polyclinic for Sleep Disorders of Duzce University Medical Faculty were included in the study. PSG and the questions related to sleep perception was applied by the same physician with face to face interview to all participants.Results: Of the patients included in the study 90 (67.2%) were male and 44 (32.8%) were female, and the mean age was 47.3±12.6 years. While there was a significant correlation (p=0.042, r=0.301) between the sleep time reported by the patients themselves after waking up in the morning and the sleep time measured by the PSG in patients without obstructive sleep apnea (OSA), there was no correlation in OSA (+) patients (p=0.269, r=0.125). Similarly, while there was a significant correlation (p=0.026, r=0.352) between the sleep latency reported by the patients themselves after waking up in the morning and the sleep latency measured by the PSG in OSA (-) patients, there was no correlation in OSA (+) patients (p=0.060, r=0.223).Conclusion: While evaluating OSA patients and explaining their treatment before and after PSG, it should be kept in mind that they might have impaired perception. Therefore, we thought that we should spend more time to patients, and to make our explanations more clearly and understandably.
