Referrals - We accept all referrals
Referrals for lung function testing can be made directly to assist treatment in primary care. Our locations have also been selected with our patients in mind, providing easy access for breathless patients.
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)
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.
