What is the purpose of this trial?

This trial aims to assist people experiencing homelessness by diagnosing and treating sleep apnea, a common sleep disorder that disrupts breathing during sleep. The trial employs digital tools, including a portable sleep monitoring device, and treatment options such as a special breathing machine and a dental device, to enhance participants' sleep and overall quality of life. Individuals currently staying in shelters who suspect they might have sleep apnea may be suitable candidates for this study. As an unphased trial, it provides participants the opportunity to access innovative sleep apnea treatments and improve their quality of life.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this digital technology is safe for diagnosing and treating sleep apnea?

Research has shown that digital devices for diagnosing sleep apnea are generally safe and meet safety standards. Many of these devices, including the Prodigy 2 used in this study, have received approval from health authorities for home use. Their design ensures easy setup and use, minimizing risks. Studies indicate that treatments like Auto-CPAP and Mandibular advancement devices (MAD) are well-tolerated by most patients. These treatments are widely used and have a strong safety record. Reporting any side effects to a healthcare provider remains important. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores innovative approaches to diagnosing and treating sleep apnea using digital technology. Unlike traditional methods that often require hospital visits for sleep studies, this trial uses the Prodigy 2, a portable device approved by Health Canada, which allows for easy, at-home sleep monitoring. This device not only records standard metrics like airflow and oxygen levels but also captures detailed brain activity to identify different sleep stages. Additionally, the trial considers patient preferences and uses advanced treatment options like Auto-CPAP and Mandibular advancement devices, potentially leading to more personalized and effective care. By combining these technologies, the trial aims to improve accessibility and accuracy in diagnosing and managing sleep apnea.

What evidence suggests that digital technology is effective for treating sleep apnea in people experiencing homelessness?

This trial will compare different treatment options for sleep apnea. Research has shown that auto-CPAP, one of the treatment options in this trial, effectively aids people with moderate to severe sleep apnea. It improves sleep quality and reduces symptoms like daytime sleepiness and high blood pressure. Using auto-CPAP for at least four hours each night lowers the risk of death compared to not using it.

Mandibular advancement devices (MADs) are another treatment option in this trial for obstructive sleep apnea. They move the lower jaw forward, reducing the severity of sleep apnea. MADs enhance sleep quality and lessen daytime tiredness. Both treatments are effective but operate differently, offering options based on individual needs and preferences. ^{6 7 8 9 10}

Trial Overview

The study involves questionnaires, portable polysomnography (a type of sleep study), and treatment for diagnosed sleep disorders. The goal is to see how patient-centered treatment affects the participants' quality of life.

How Is the Trial Designed?

Group I: Treatment Experimental Treatment 2 Interventions

Description: Individuals who are diagnosed with sleep apnea, and are deemed eligible for treatment, will receive a treatment option based on Canadian Agency for Drugs and Technologies in Health (CADTH), physician recommendations, and the participant's preferences. In this study, auto-titrating positive airway pressure (Auto-CPAP) and Mandibular advancement device (MAD) will be the main modalities of treatment.

Group II: Screening Experimental Treatment 1 Intervention

Also, the participants are asked to complete the following questionnaires with the help of a research assistant. The result of the application will be combined with the questionnaires for the final risk assessment. * Participant Demographics questionnaire * STOP-Bang * Insomnia severity index * Epworth sleepiness score (ESS) * Functional outcome of Sleep Questionnaire (FOSQ-10) * Beck Depression Inventory (BDI) * Chalder Fatigue Scale (CFQ) * Health Information Technology Usability Evaluation Scale (Health-ITUES) Questionnaire * Oral Health Impact Profile - 14 (OHIP-14) * Asthma Control Test (ACT) * Primary care post-traumatic stress disorder (PTSD) screen (PC-PTSD-5) * A survey to help identify barriers to treatment in the people experiencing homelessness (General Survey)

Group III: Diagnosis Experimental Treatment 2 Interventions

Description: A portable polysomnography device to assess sleep apnea in individuals at risk of sleep apnea. The Prodigy 2 has Health Canada Approval for home sleep study. The system is small, easy to use, and can be setup by a research technician at the shelter. Prodigy measures thoraco-abdominal motion, nasal airflow, oxyhemoglobin saturation (SpO2), cardiac function with electrocardiogram and leg movement. The main advantage of Prodigy 2 to other portable devices is that it has a simple headband to record forehead electroencephalogram to detect rapid eye movement (REM) and non-REM sleep stages. After processing Prodigy 2 signals, an apnea-hypopnea index (AHI) will be calculated for each participant based on the number of respiratory events (apneas or hypopneas) per hour of sleep. The investigators will measure AHI, REM AHI, non-REM AHI, AHI in different body postures, snoring duration, arousal index, sleep time with SpO2\<90%, oxygen desaturation index (ODI), and sleep efficiency.

Recent advancements in technology have led to the development of various innovative diagnostic methods for sleep apnea, such as portable polygraphy and mattress-like devices, which are more accessible and comfortable compared to traditional polysomnography.

These new diagnostic tools are categorized based on their physical structure and sensing capabilities, highlighting their unique strengths and suitability for different applications, ultimately improving the experience for both patients and healthcare providers.

A review of 41 studies on digital tools for obstructive sleep apnea (OSA) screening found that some smartphone-based and wearable devices showed high accuracy, with the best performing tool achieving an area under the curve (AUC) of 0.99, sensitivity of 96%, and specificity of 92%.

Despite these promising results, most tools lack external validation against the gold standard of polysomnography, indicating a need for further quality studies before these digital tools can be reliably used in clinical practice.

The Xiaomi Mi Band 5 showed 78% accuracy in measuring sleep stages compared to polysomnography, with better performance in individuals without sleep disorders, indicating it may be useful for general sleep monitoring.

However, the device overestimated total sleep time and light sleep while underestimating wake after sleep onset and REM sleep, suggesting it may not be fully reliable for detailed sleep analysis, especially in those with sleep disorders.
