HealthDay News — The American College of Physicians (ACP) has released a new evidence-based clinical practice guideline for the diagnosis of obstructive sleep apnea (OSA) in adults. The guideline was published Annals of Internal Medicine.
Amir Qaseem, MD, PhD, from the ACP in Philadelphia, and colleagues developed a guideline, based on published literature from 1966 through May 2013, to provide clinical recommendations for the diagnosis of OSA in adults.
The researchers found low-quality evidence supporting a weak recommendation for performing a sleep study in patients with unexplained daytime sleepiness.
A second weak recommendation, based on moderate-quality evidence, advises diagnostic testing with polysomnography in patients suspected of having OSA. When polysomnography is not available, diagnostic testing with portable sleep monitors may be used as an alternative in patients without serious comorbidities. Polysomnography and portable monitors measure or estimate the apnea-hypopnea index, which is the number of apnea or hypopnea events per hour during sleep.
“Assessment of OSA in the absence of daytime sleepiness or treatment of persons with low apnea-hypopnea index scores is low-value care because evidence to date indicates that neither improves clinical outcomes,” the authors wrote.
