Screening Tools for Obstructive Sleep Apnea (OSA) in Hospitalized Medical Patients
NCT01340781 · View on ClinicalTrials.gov ↗
Study Summary
The prevalence of obstructive sleep apnea (OSA) in patients admitted to the hospital is likely significantly higher than the general population as hospitalized patients carry a high prevalence of co-morbid conditions, such as diabetes and cardiovascular diseases, that are commonly associated with OSA. The true prevalence of OSA in hospitalized patients is not known, though there is limited data suggesting that the rate of OSA in hospitalized patients is indeed high. Two studies have reported on the rate of polysomnographic (PSG) diagnosis of OSA in patients referred for OSA evaluation while in-hospital. These studies reported frequencies of 77% (in a retrospective study of 100 patients) and 88-100% (in an observational study of 250 patients). Similarly, 2 studies evaluated the prevalence of sleep disordered breathing in patients admitted with acutely decompensated heart failure, finding frequencies of sleep apnea in 97% (prospective study of 29 patients studied with PSG) and 75% (prospective study of 395 consecutive patients studied with portable monitors). However, all of these studies are limited by either study design (retrospective), small numbers, limited channel portable monitoring, or evaluations of highly select patient populations. Furthermore, none of these studies examined screening tools that may help to identify which patients are at risk for OSA and thus might require the more extensive and expensive objective testing. This study will test the following hypotheses: 1. The prevalence of OSA in unselected hospitalized medical patients will be more than 50% of the study population. Specific Aim 1: To determine the prevalence of OSA in a group of unselected hospitalized medical patients by a combination of sleep symptoms and PSG performed while in-hospital. 2. Screening tools will be able to accurately identify OSA in hospitalized medical patients. Specific Aim 2: To determine the accuracy of different screening questionnaires for the diagnosis of O

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01340781
The ClinicalTrials.gov registry entry for NCT01340781 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 110 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is MetroHealth Medical Center, which has 29 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Obstructive Sleep Apnea appearing as the primary indexed condition, and to 1 intervention — of which Polysomnogram is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01340781 reports 1 study location spanning 1 distinct geographic area — top geographies include Ohio. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
