• #1 Obstructive Sleep Apnea Diagnosis and Management

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6140019/

  The diagnosis and treatment of obstructive sleep apnea is discussed in the context of recent diagnostic and therapeutic advances. […] Obstructive sleep apnea (OSA) is characterized by episodes of breathing cessation or shallow breathing in sleep. […] According to a recent report by American Academy of Sleep Medicine (AASM), OSA affects 12% of US adult population totaling 29.4 million individuals and 80% of these are undiagnosed. […] The sleep tests are classified depending on the number of channels being monitored during the test. Type 1 test is the in-lab attended sleep study or polysomnography (PSG), which is the gold standard test to diagnose OSA. […] AASM recommends HSAT in patients with high pretest probability after comprehensive sleep evaluation. HSAT should not be used as a screening tool and is not appropriate in patients with comorbid severe pulmonary disease, congestive heart failure, neuromuscular disease or other sleep disorders like periodic limb movement disorder (PLMD), narcolepsy, or parasomnias.

  https://my.clevelandclinic.org/health/diseases/24443-obstructive-sleep-apnea-osa

  Obstructive sleep apnea can lead to potentially life-threatening complications. […] A healthcare provider will diagnose OSA after taking your medical history, performing a physical exam and recommending tests. […] Two tests can help diagnose OSA, including: Overnight sleep study (polysomnogram): This is an overnight test where you sleep in a medical facility where they monitor your sleep. […] Home sleep apnea testing: This is similar to an overnight sleep study but doesn’t involve brain wave monitoring and other types of sensors and you get to stay home. […] If you suspect you or a loved one has OSA, you might be able to help a healthcare provider diagnose it. […] Treatment for OSA may include: Making lifestyle changes like sleeping position adjustments (not sleeping on your back) or maintaining a weight that’s healthy for you.

  Find out how OSA is diagnosed, including what happens at a sleep clinic, the tests that are used in a sleep study, and how you can get the right treatment. […] Getting a diagnosis of OSA can help you get the right treatment and advice about lifestyle changes that can help. […] Diagnosing OSA early can reduce your risk of complications. […] If they have typical OSA symptoms, your child should be referred to a sleep clinic for tests to get a firm diagnosis. […] Based on your scores and how sleepiness affects you, your GP may refer you to a sleep clinic. This is so you can do further tests, including a sleep study, to diagnose OSA. The tests will also show if your OSA is mild, moderate or severe. […] Sleep clinics are specialist clinics that assess, diagnose and treat people with a range of sleep problems, including OSA.

  Your health care provider may make an evaluation based on your symptoms and a sleep history, which you can provide with help from someone who shares your bed or your household, if possible. […] You’re likely to be referred to a sleep disorder center. There, a sleep specialist can help you determine your need for further evaluation. […] An evaluation often involves overnight monitoring of your breathing and other body functions during sleep testing at a sleep center. Home sleep testing also might be an option. Tests to detect sleep apnea include: […] Nocturnal polysomnography. During this test, you’re hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep. […] Home sleep tests. Your health care provider might provide you with simplified tests to be used at home to diagnose sleep apnea. These tests usually measure your heart rate, blood oxygen level, airflow and breathing patterns. Your provider is more likely to recommend polysomnography in a sleep testing facility, rather than a home sleep test, if central sleep apnea is suspected.

  https://www.lung.org/lung-health-diseases/lung-disease-lookup/sleep-apnea/symptoms-diagnosis

  How Obstructive Sleep Apnea Is Diagnosed […] To help diagnose if you have sleep apnea your healthcare provider will look at the following: Health History and Physical Exam. Your healthcare provider will want to know about your sleep and health habits, including how much sleep you get, how long it takes to fall asleep and whether you sleepwalk or talk while asleep. Your medications will be reviewed for their effects on sleep and you may be asked about your family history, because sleep apnea runs in families. A physical exam will help rule out other medical conditions and will look for anything making your upper airway narrower, such as enlarged tonsils or a small jaw, that may contribute to sleep apnea. […] […] […] Sleep Study. You may be asked to complete a sleep study at home or at a sleep center. A sleep study monitors and records your breathing, heart rate and oxygen levels overnight. In a sleep lab, this non-invasive test will use sensors attached to your head and body connected by long wires to a computer. The results, which may include measuring heart, lung, brain activity, breathing patterns, arm and leg movements and oxygen levels while asleep will help your healthcare provider make a diagnosis of sleep apnea. A sleep study completed in a sleep center provides more information than can be collected when using a portable sleep apnea test at home. You also may be asked to complete a sleep diary to keep track of your sleeping patterns and how you feel to assist with diagnosing your condition.

  Diagnosis of obstructive sleep apnea (OSA) begins with a complete medical and sleep history and medical exam. This can include detailed questions about patterns, duration, quality of sleep; prevalence and frequency of snoring; daytime fatigue; and morning symptoms of sore throat or headache. […] A medical history review is typically followed by a medical exam to identify potential anatomical causes for OSA including enlarged tonsils, adenoids, soft palate tissue, or uvula. […] The definitive test for diagnosing OSA is the polysomnogram, an overnight sleep test performed by a specialist in a sleep lab. Polysomnography measures breathing patterns, breathing rates, blood oxygen levels, blood pressure, and muscle and brain activity during sleep. […] Throughout the test period, episodes of apnea and hypopnea are counted per hour to diagnose OSA and determine its severity.

  Box 2 outlines the roles that GPs have in diagnosing and managing OSA. […] The aim of this paper is to improve awareness of common risk factors for and clinical presentation of OSA in primary care to improve patient health outcomes. […] OSA screening questionnaires, such as the OSA50, STOP-Bang and Berlin questionnaires, can help GPs to identify patients who are at high risk of having OSA. […] The OSA screening questionnaires have similar diagnostic accuracy for detection of moderatesevere OSA and are highly sensitive but have low specificity (ie high false positive rate) for detecting moderatesevere OSA. […] Thus, a positive screening questionnaire result by itself does not confirm a diagnosis of OSA, and the patient should proceed to sleep study testing. […] If GPs wish to directly request a PSG, the patient needs to have a high risk of symptomatic, moderatesevere OSA, as indicated by a positive response to an OSA screening questionnaire (an OSA50 5, STOP-Bang 3 or high risk on the Berlin questionnaire) plus at least mild daytime sleepiness (ESS 8).

  https://www.mdpi.com/2504-463X/5/2/16

  This clinical implication has led to further pursuit in the understanding of the heterogeneity of OSA to improve the diagnosis and treatment of the disorder. […] The screening tool includes four self-reported symptoms (loud snoring, excess daytime sleepiness, witnessed sleep apnea, and hypertension) and four physical traits (BMI > 35, age > 50 years, neck circumference > 40 cm, and male gender). […] The authors proposed that the NoSAS score may be useful to help predict other disease comorbidities, especially CVD in patients with OSA. […] The usage of biomarkers has been studied to augment phenotyping approaches. […] These biomarkers may help to screen for the presence of OSA. […] Drug-induced sleep endoscopy is the current preferred diagnostic technique to assess the dynamic upper airway in a state that mimics natural sleep in patients with obstructive sleep apnea.

• #10 Sleep Apnea (Obstructive) | American Dental Association

  https://www.ada.org/resources/ada-library/oral-health-topics/sleep-apnea-obstructive

  Obstructive sleep apnea is often undiagnosed and untreated, but common signs and symptoms of OSA can be identified in various clinical settings, including dental practice. […] Diagnosis of OSA is made by a physician or trained sleep specialist after comprehensive assessment of the patient, including medical history, physical examination and diagnostic testing. […] The reference standard for OSA diagnosis is an overnight, attended sleep study (polysomnogram). […] An in-laboratory sleep study quantifies obstructed breathing events using the apnea-hypopnea index (AHI), which presents an average measure of apneas and hypopneas recorded per hour of sleep. […] Clinical questionnaires to assist with conducting OSA risk assessment are presented in Table 3. […] The STOP-Bang Questionnaire is an eight-question checklist of symptoms associated with increased risk of OSA, which has been recommended as a screening tool with moderate-quality evidence.

• #14 The OSA Diagnosis Journey — BetterNight

  https://betternight.com/news/the-osa-diagnosis-journey

  Sleep apnea is characterized by repeated cycles of paused breathing that occur throughout the night, resulting in reduced blood oxygen levels. […] Once a patient shows sleep apnea symptoms and has visited their primary care physician, diagnostic screenings are the next step. These screenings vary in price and complexity, but all aim to further define a patients level of sleep apnea risk. Polysomnography, also known as a sleep study, is a complete series of tests used to diagnose sleep disorders. Polysomnography is considered the gold standard in sleep apnea diagnosis and is conducted with an attending sleep specialist in a clinical setting, usually a hospital or sleep center. […] Another screening tool used to determine OSA risk is the NoSAS (Neck circumference, Obesity, Snoring, Age, Sex) score, developed in Lausanne, Switzerland. Similar to STOP Bang, this measurement determines the level of risk by assigning a score based on answers to OSA-related questions. A patient has a high probability of OSA if they have a NoSAS score of 8 or higher.

  https://www1.racgp.org.au/ajgp/2019/april/adult-obstructive-sleep-apnoea

  Therefore, screening questionnaires alone are inadequate for confirming a diagnosis, and patients who have a positive screening test should proceed to further evaluation with formal sleep study testing to confirm the presence or absence of OSA. […] The new Medicare Benefits Schedule (MBS) rules have resulted in two potential pathways to a sleep study. […] The gold standard test for diagnosing OSA is with in-laboratory full polysomnography (PSG) with a sleep technician in attendance throughout the night. […] Results from home PSG (type 2) testing have been shown to have a high level of agreement when compared with in-laboratory PSG for the diagnosis of OSA. […] An initial clinical assessment, which includes validated questionnaires, helps triage patients to sleep testing pathways that have now become embedded in the MBS.

  Obstructive sleep apnea (OSA) is likely underdiagnosed in Canada; however, lack of appropriate treatment puts many at risk of poor quality of life, comorbidity, motor vehicle crashes and increased health care utilization. […] Polysomnography is the gold standard for diagnosis; however, home sleep apnea testing may be used to confirm the diagnosis in symptomatic patients with a high pretest probability of OSA and without clinically important cardiopulmonary comorbidity. […] By consensus, the International Classification of Sleep Disorders defines OSA as the presence of symptoms or certain comorbidities associated with five or more predominantly obstructive respiratory events per hour or by 15 or more predominantly obstructive respiratory events per hour in asymptomatic patients. […] The gold standard for diagnosis of OSA is attended polysomnography (level I study), which involves collection of seven or more data channels, including electroencephalogram and electrooculogram for sleep staging, electromyogram, electrocardiogram and respiratory channels.

  https://www.aafp.org/pubs/afp/issues/2016/0901/p355.html

  Obstructive sleep apnea is a common disorder that causes patients to temporarily stop or decrease their breathing repeatedly during sleep. […] The diagnostic standard for obstructive sleep apnea is nocturnal polysomnography in a sleep laboratory. […] In addition to risk factors, numerous signs and symptoms can suggest OSA, but polysomnography is the diagnostic standard. […] Sleep studies performed in a sleep laboratory or in the home can quantify the apnea-hypopnea index, which is required to diagnose OSA. Apnea is a complete obstruction of airflow, and hypopnea is a partial obstruction of airflow; both must last a minimum of 10 seconds. […] An apnea-hypopnea index of 15 or more events per hour, or five or more events per hour in the presence of symptoms or cardiovascular comorbidities, is diagnostic for OSA. […] Home sleep apnea tests are considered to be less accurate than type-I studies because of data loss from detached or malfunctioning monitoring equipment. […] Home sleep apnea tests can be an alternative to type-I studies in patients who are unable to present to a sleep laboratory.

  Diagnosis of Obstructive Sleep Apnea Syndrome – CAM 20118 […] Obstructive sleep apnea (OSA) syndrome is characterized by repetitive episodes of upper airway obstruction due to the collapse of the upper airway during sleep. Polysomnography and portable sleep apnea testing (with sensors for respiratory effort, airflow, and oxygen saturation, or alternatively with peripheral arterial tone [PAT], actigraphy, and oxygen saturation) are established methods for diagnosing OSA. […] The criterion standard for a diagnosis of sleep disorders is a polysomnogram performed in a sleep laboratory. A standard polysomnogram includes electroencephalogram (EEG), submental electromyogram, and electrooculogram (to detect rapid eye movement sleep) for sleep staging.

  Drug Induced Sleep Endoscopy (DISE) – this diagnostic tool is a nasolaryngoscopy performed under sedation to examine the airway while the patient is falling asleep. The patient is brought into a procedure room or operating room and given an intravenous line. Much like a colonoscopy or EGD, medication is given to allow the patient to fall asleep while still breathing on their own. The medication is titrated to the point where the patient is snoring and mimicking their sleep apnea episodes and the procedure generally takes about 10 minutes to complete. This exam, compared to the awake office-based exam, is conducted to better understand the areas of collapse that are occurring, which are causing snoring and episodes related to sleep apnea. DISE is an extremely useful tool to more accurately ascertain the anatomic reasons behind sleep apnea, and to allow for more targeted therapy if surgery is decided upon.

  Obstructive sleep apnea (OSA) is likely underdiagnosed in Canada; however, lack of appropriate treatment puts many at risk of poor quality of life, comorbidity, motor vehicle crashes and increased health care utilization. […] Polysomnography is the gold standard for diagnosis; however, home sleep apnea testing may be used to confirm the diagnosis in symptomatic patients with a high pretest probability of OSA and without clinically important cardiopulmonary comorbidity. […] By consensus, the International Classification of Sleep Disorders defines OSA as the presence of symptoms or certain comorbidities associated with five or more predominantly obstructive respiratory events per hour or by 15 or more predominantly obstructive respiratory events per hour in asymptomatic patients. […] The gold standard for diagnosis of OSA is attended polysomnography (level I study), which involves collection of seven or more data channels, including electroencephalogram and electrooculogram for sleep staging, electromyogram, electrocardiogram and respiratory channels.

  A diagnosis of narcolepsy may be delayed if obstructive sleep apnea (OSA) is considered the only condition. Patients should be routinely screened clinically for symptoms of narcolepsy. These patients do not typically have normal sleepiness when OSA has been treated; they may experience improvement in sleepiness, but it is important to question the diagnosis of sleepiness due to OSA despite ideal treatment. […] The indices commonly used to assess sleep disordered breathing (SDB) are the apnea-hypopnea index (AHI) and the respiratory disturbance index (RDI). […] According to the Centers for Medicare Medicaid Services criteria for the positive diagnosis and treatment of obstructive sleep apnea, a positive test for OSA is established if either of the following criteria using the AHI or the RDI is met: AHI or RDI greater than or equal to 15 events per hour, or AHI or RDI greater than or equal to 5 and less than or equal to 14 events per hour with documented symptoms of excessive daytime sleepiness (EDS); impaired cognition; mood disorders; insomnia; or documented hypertension, ischemic heart disease, or history of stroke.

  A healthcare provider will diagnose sleep apnea by asking you questions about your symptoms and medical history. If they suspect the condition, they’ll recommend testing to confirm a diagnosis. […] The most common tests for sleep apnea include: Polysomnogram. This is an overnight test that involves wearing sensors that monitor your heart rate, breathing, blood oxygen levels, brain waves and more. […] Home sleep apnea testing. This is the at-home version of a sleep study, but it doesn’t involve brain wave monitoring. There are some limitations to this test; for example, it can’t diagnose central sleep apnea. […] Healthcare providers use the apnea/hypopnea index (AHI) to determine the severity of a sleep apnea diagnosis. The AHI measures the average hourly number of apnea (when you stop breathing while asleep) and hypopnea (decreased airflow) events. The severity levels of sleep apnea are: Mild sleep apnea (AHI 5-14 events per hour), Moderate sleep apnea (15-29 events per hour), Severe sleep apnea (30 or more events per hour).

  Diagnosis of Obstructive Sleep Apnea Syndrome – CAM 20118 […] Obstructive sleep apnea (OSA) syndrome is characterized by repetitive episodes of upper airway obstruction due to the collapse of the upper airway during sleep. Polysomnography and portable sleep apnea testing (with sensors for respiratory effort, airflow, and oxygen saturation, or alternatively with peripheral arterial tone [PAT], actigraphy, and oxygen saturation) are established methods for diagnosing OSA. […] The criterion standard for a diagnosis of sleep disorders is a polysomnogram performed in a sleep laboratory. A standard polysomnogram includes electroencephalogram (EEG), submental electromyogram, and electrooculogram (to detect rapid eye movement sleep) for sleep staging. Polysomnography (PSG) also typically includes electrocardiography and monitoring of respiratory airflow and effort, snoring, oxygen desaturation, and sleep position. An attended study ensures that the electrodes and sensors are functioning adequately and do not dislodge during the night. […] Obstructive sleep apnea is widely underdiagnosed with up to 95% of individuals with clinically significant OSA reporting no prior OSA diagnosis. Moreover, underdiagnosis is particularly prevalent in Black patients. […] A variety of devices have been developed specifically to evaluate OSA at home. They range from portable full PSG systems to single-channel oximeters. Available devices evaluate different parameters, which may include oximetry, respiratory and cardiac monitoring, and sleep/wake activity, but most portable monitors do not record EEG activity. […] A single unattended (unsupervised) home sleep apnea test with a minimum of 3 recording channels with the following sensors: nasal pressure, chest and abdominal respiratory inductance plethysmography, and oximetry; or alternatively peripheral arterial tone (PAT), oximetry, and actigraphy may be considered MEDICALLY NECESSARY in adults who are at high-risk for obstructive sleep apnea (OSA) and have no evidence of a health condition that might alter ventilation or require alternative treatment.
