Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the diagnostic value of overnight pulse-oximetry as a screeningstool for OSAS in the first line in terms of positive predictive value and sensitivity. Polygraphy, evaluated using both quantitative and qualitative methods, is hereby considered the gold standard. | — |
Secondary
| Measure | Time frame |
|---|---|
| i) Negative predictive value and specificity of pulse-oximetry as diagnostic marker for OSAS in the first line. ii) Negative predicitive value, positive predictive value, sensitivity, and specificity of the Philips questionnaire as diagnostic marker for OSAS. iii) Usability of DiagnOSAS for patients. iv) Realized cost savings when using DiagnOSAS with respect to the gold standard. | — |
