This article presents information on a study related to clinical usefulness of home oximetry compared with polysomnography for assessment of sleep apnea. The study was made on 307 patients with a history suggestive of obstructive sleep apnea (OSA) associated with somnolence or fatigue. Exclusion criteria were a non-respiratory sleep disorder as the primary reason for referral, absence of daytime symptoms, important comorbid conditions, and physiologic consequences of OSA. Overall, physicians predicted success in 50% of patients, but only 42% met the criterion for improvement. The proportion of improved patients in each category was similar to the proportion predicted by physicians, except for the 50% to 75% category in which the rate of improvement was lower than predicted.
