We evaluated the sensitivity, specificity, positive predictive value, and negative predictive value of BQ and STOP-BANG scores for identifying a respiratory disturbance index (RDI) >5/hour. Patients were screened with BQ and Stop Bang and then submitted to a PSG.During 2013, 162 patients with suspected sleep disorders were referred to our sleep clinic. Fifty two percent were male, age 53.5±14.3, BMI 29.8±16,6 Kgm2. 62% had a positive PSG (IDR>5); 28% mild, 18% moderate and 16% severe OSA. A total of 75.3% scored positive in the BQ (positive in at least two categories) and 40.7% scored >4 in the STOP-Bang questionnaire. For BQ sensitivity was 83.2%, specificity was 37.7%, PPV was 68.9% and NPV was 57.5% (positive likelihood ratio: 1.34 95% 1.08-1.65). For STOP-Bang sensitivity was 56%, specificity was 83.6%, PPV was 84.8% and NPV was 53.7% (positive likelihood ratio: 3.42 95% 1.8-6.18)We concluded that these questionnaires alone cannot reliably predict the presence of OSA. Objective physiological measurement is critical for the diagnosis or exclusion of OSA. ER -
