Anesthesiology News reports on false-positives in obstructive sleep apnea screening.

A widely used screening tool for obstructive sleep apnea in children is wrong more than 75% of the time compared with polysomnography, Canadian researchers found.

The study found that the 16-item American Society of Anesthesiologists (ASA) screening tool for moderate to severe obstructive sleep apnea (MSOSA) has a 78% false-positive rate in pediatric patients compared with polysomnography (PSG), which is considered the gold standard method for identifying the breathing disorder.
