Screening for obstructive sleep apnea in patients presenting for snoring surgery.
Excessive mortality is associated with obstructive sleep apnea (OSA). Therefore it is important to diagnose OSA in patients presenting for snoring surgery. A prospective study was performed to develop screening models to detect OSA compared with universal polysomnography for sensitivity and cost. Multivariate analysis of 150 consecutive patients was based on clinical data, questionnaire data, and polysomnography. Two screening models obtained 100% sensitivity and reduced the need for polysomnograms. Cost savings of screening based on clinical data was projected to be $35 to $80 per patient using reported prevalence rates of OSA among snorers. A screening model for OSA using clinical data alone is more cost-effective than one that combines these data with pulse oximetry data, but savings over universal polysomnography were modest.
