OSA50 Questionnaire
The OSA50 questionnaire was developed by a group of Australian sleep medicine researchers who aimed to create a brief, four-item OSA screening tool for use in general practice. They established that the four items that best predicted a diagnosis of severe OSA (ie AHI ≥30 events/hour) were:
-
obesity (by waist circumference)
-
snoring
-
witnessed apneas
-
age ≥50 years.
​
Weightings from results of logistic regression analyses were used to create a simple screening tool with a maximum score of 10 points. An OSA50 score ≥5 points was found in a validation sample to have 94% sensitivity, with 31% specificity for identifying moderate-to-severe OSA.
