AHCPR Report on Diagnosis of Sleep Apnea. . is the ‘gold standard’ for diagnosis. – Agency for Health Care Policy and Research – Overnight full-channel polysomnography – full PSG
Overnight full-channel polysomnography (full PSG) remains the “gold standard” for the diagnosis of sleep apnea, according to a study sponsored by the Agency for Health Care Policy and Research (AHCPR) under its evidence-based practice program. Because the full PSG is very expensive and is difficult to interpret, the primary objective of the AHCPR study was to evaluate the diagnostic accuracy of alternatives to full PSG for the diagnosis of sleep apnea. The sleep apnea evidence report is the first in a new series of evidence reports and technology assessments sponsored by the AHCPR.
Diagnostic approaches that might be alternatives to full PSGs or used as screening tests to better select patients for PSG testing include partial-channel PSGs, partial night or daytime PSGs, portable sleep monitoring devices for use at home, radiologic imaging of the head and neck, magnetic resonance imaging and computed tomography scans, anthropomorphic measurements, nasopharyngeal and laryngeal endoscopic measurements of both structure and function, and focused questionnaires. The study concluded that several of these less expensive and less time- consuming tests appear promising for the accurate diagnosis of sleep apnea.
Specific recommendations were not included in the report, but researchers believe that this synthesis of the evidence-based literature will serve as an information resource for physicians and developers of guidelines.
A summary of the report titled “Systematic Review of the Literature Regarding the Diagnosis of Sleep Apnea” is available on the AHCPR Web site at http://www.ahcpr.gov. The full report may be obtained free from the AHCPR Publications Clearinghouse by calling 800-358-9295.
