{'briefSummary': "Obstructive sleep apnea (OSA) is the most common type of sleep apnea. OSA affects an estimated 18-40 million adults and 0.7-3% of all children in the US. The marketplace currently does not have an affordable, easy-to-use, over-the-counter, home-based OSA screening device. An affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. The specific goal of this project is to compare the Zansors® micro sleep sensor screening device against gold-standard polysomnography to establish the device's preliminary validity to screen for OSA accurately.", 'detailedDescription': "Obstructive Sleep Apnea (OSA) results in tiredness, depression and fatigue, and has several associated common comorbidities. It is believed that over 80% of OSA remains undiagnosed. Poorer and disadvantaged communities are at higher risk for sleep disorders, including OSA, even after accounting for other risk factors. The gold-standard method for diagnosing OSA is in-laboratory polysomnography; however, this procedure is generally available only to patients with health insurance due to its high cost. As a result, communities at particularly high risk for OSA are less likely to have this serious sleep disorder appropriately diagnosed and treated.\n\nAn affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. Zansors® has developed a bioengineered, semiconductor prototype that measures breathing and movement during sleep. It is a 1.5 x 2.5 x 0.2 inch wireless package using four key technologies:\n\n1. an adjustable microphone;\n2. a 3-axis accelerometer;\n3. embedded algorithms to measure sleep events; and\n4. acrylic adhesive.\n\nThe product will be designed as an FDA-approved over-the-counter device that the patient can wear during sleep and wake up with a color score of red, yellow, or green depending on their sleep apnea status. The features of this product include that it is home-based; easy to use; non-invasive; wireless; disposable; low cost ($20-50); and presents easily understandable test results. However, such a device must first be validated against gold-standard polysomnography.\n\nThe specific goal of this project is to compare the Zansors® micro sleep sensor screening device against gold-standard polysomnography to establish the device's preliminary validity to screen for OSA accurately."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Must be over 18 and referred by medical staff for an overnight assessment for suspected sleep apnea\n\nExclusion Criteria:\n\n* Pregnancy\n* Heart disease including congestive heart failure or a pacemaker\n* Breathing disorder (emphysema or chronic obstructive breathing disorder)\n* Neurological disorder such as Parkinson's Disease\n* Restless leg syndrome or Periodic limb movement\n* Allergies to metal\n* Pre-existing skin conditions where sensor would be attached"}, 'identificationModule': {'nctId': 'NCT02814227', 'briefTitle': 'Validation of Sleep Apnea Screening Device', 'organization': {'class': 'OTHER', 'fullName': 'University of Michigan'}, 'officialTitle': 'Wireless Sensor Patch for Reducing Barriers to In-home Sleep Apnea Screening', 'orgStudyIdInfo': {'id': 'R41MD008845-01', 'link': 'https://reporter.nih.gov/quickSearch/R41MD008845-01', 'type': 'NIH'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Zansors® sleep screening device', 'description': 'Zansors device compared to overnight polysomnography', 'interventionNames': ['Device: Zansors® sleep screening device']}], 'interventions': [{'name': 'Zansors® sleep screening device', 'type': 'DEVICE', 'description': 'Intervention is the validation of a sleep apnea screening device against the gold-standard assessment of in-laboratory polysomnography', 'armGroupLabels': ['Zansors® sleep screening device']}]}, 'contactsLocationsModule': {'locations': [{'zip': '48109', 'city': 'Ann Arbor', 'state': 'Michigan', 'country': 'United States', 'facility': 'University of Michigan', 'geoPoint': {'lat': 42.27756, 'lon': -83.74088}}], 'overallOfficials': [{'name': 'J.
