The Clinical Impact of Systematic Screening for Obstructive Sleep Apnea in a Type 2 Diabetes Population-Adherence to the Screening-Diagnostic Process and the Acceptance and Adherence to the CPAP Therapy Compared to Regular Sleep Clinic Patients.

Front Endocrinol (Lausanne) 2018 29;9:714. Epub 2018 Nov 29.

Second Internal Medicine Department, Vinohrady Teaching Hospital, Prague, Czechia.

Obstructive sleep apnea (OSA) is a common disorder in Type 2 diabetes (T2D) patients further increasing their already high cardiovascular risk. As T2D patients typically not report OSA symptoms, systematic screening for OSA in this population is warranted. We aimed to determine the readiness of T2D patients to undergo screening and to compare their adherence to continuous positive airway pressure (CPAP) therapy with "regular" sleep clinic patients who typically seek medical advice on their own initiative.

Automatic identification of sleep and wakefulness using single-channel EEG and respiratory polygraphy signals for the diagnosis of obstructive sleep apnea.

J Sleep Res 2018 Nov 26:e12795. Epub 2018 Nov 26.

Département de Pneumologie, Centre Hospitalier Universitaire, Angers, France.

Polysomnography (PSG) is necessary for the accurate estimation of total sleep time (TST) and the calculation of the apnea-hypopnea index (AHI). In type III home sleep apnea testing (HSAT), TST is overestimated because of the lack of electrophysiological sleep recordings. The aim of this study was to evaluate the accuracy and reliability of a novel automated sleep/wake scoring algorithm combining a single electroencephalogram (EEG) channel with actimetry and HSAT signals.

Sleep 2018 Oct 22. Epub 2018 Oct 22.

Division of Sleep and Circadian Disorders, Brigham and Women's Hospital, Boston, MA.

Rationale: While short sleep duration has been linked to unhealthy dietary patterns, little is known about the association of obstructive sleep apnea (OSA), a disorder characterized by sleep fragmentation, and diet.

Objective: Investigate associations between diet quality and OSA in the Multi-Ethnic Study of Atherosclerosis and assess whether reductions in slow wave sleep (stage N3) and rapid eye movement (REM) sleep are potential mediators for these associations.

Methods: A diverse population (N = 1,813) completed a food frequency questionnaire and underwent Type 2 in-home polysomnography, which included measurement of N3 and REM sleep and apnea-hypopnea index (AHI). Read More

Addition of frontal EEG to adult home sleep apnea testing: does a more accurate determination of sleep time make a difference?

Sleep Breath 2018 Dec 11;22(4):1179-1188. Epub 2018 Oct 11.

Division of Pulmonary, Critical Care, and Sleep Medicine, New York University School of Medicine, New York, NY, USA.

Rationale: Home sleep apnea testing (HSAT) typically does not include electroencephalogram (EEG) monitoring for sleep assessment. In patients with insomnia and low sleep efficiency, overestimation of the sleep period can result from absence of EEG, which will reduce sleep disordered breathing (SDB) indices and may lead to a false-negative result.

Objective: To validate a single channel frontal EEG for scoring sleep versus wake against full EEG during polysomnography, and then to examine the utility of adding this single channel EEG to standard HSAT to prevent false-negative results. Read More

Polysomnography for Obstructive Sleep Apnea Should Include Arousal-Based Scoring: An American Academy of Sleep Medicine Position Statement.

J Clin Sleep Med 2018 Jul 15;14(7):1245-1247. Epub 2018 Jul 15.

Division of Sleep Medicine, Department of Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.

Abstract: The diagnostic criteria for obstructive sleep apnea (OSA) in adults, as defined in the International Classification of Sleep Disorders, Third Edition, requires an increased frequency of obstructive respiratory events demonstrated by in-laboratory, attended polysomnography (PSG) or a home sleep apnea test (HSAT). However, there are currently two hypopnea scoring criteria in The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications (AASM Scoring Manual). This dichotomy results in differences among laboratory reports, patient treatments and payer policies. Read More

As the cost of health care continues to escalate, payers are adapting by moving away from models based on traditional fee-for-service reimbursement to models focused on rewarding care delivery that reduces costs and improves quality. These alternative payment models (APMs) are being introduced by government and commercial payers and will likely become the norm over time. Recent changes in sleep medicine related to advances in technology and approaches by payers for the management of OSA make this an appropriate time to incorporate the delivery of sleep medicine services into APMs. Read More

A Comparison of Two Nights of Ambulatory Sleep Testing in Arrhythmia Patients.

Sleep Disord 2018 3;2018:2394146. Epub 2018 Jun 3.

Department of Psychiatry, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada.

Introduction: Obstructive sleep apnea (OSA) is common and usually underdetected in patients with cardiac arrhythmia. Ambulatory sleep testing may provide an alternative method for detection of OSA under realistic conditions compared to in-laboratory polysomnography. We aimed to (1) determine the sleep architecture in arrhythmia patients; (2) detect differences in sleep parameters between patients with and without OSA; and (3) compare the results of two consecutive nights of unattended ambulatory sleep testing.

Patient satisfaction with sleep study experience: findings from the Sleep Apnea Patient-Centered Outcomes Network.

Sleep 2018 Aug;41(8)

Sleep Apnea Patient-Centered Outcomes Network.

Study Objectives: Home sleep apnea testing (HSAT) is increasingly used as an alternative to laboratory-based polysomnography (PSG) for the diagnosis of obstructive sleep apnea. Patient satisfaction with sleep testing performed at home or in the lab has been sparsely assessed, despite its potentially pivotal role in determining patients' acceptance of sleep apnea treatment. We hypothesize that satisfaction in clinical practice may differ from what has been previously reported within the research setting. Read More
