What researchers measure

Primary outcomes

  1. Number of patients with a positive DES-OSA score

    Comparison of the result of the DES-OSA score with results of previously describes scores (STOP-BANG, OSA50 and P-SAP).

    Time frame: Baseline

Secondary outcomes

  1. Number of patients with a positive STOP-Bang score and a positive PSG (PolySomnoGraphy)

    For the patients with a positive STOP-Bang score: we will make a PSG. After this one, we will compare the result of four scores (STOP-Bang, OSA50, P-SAP and DES-OSA) and the result of the PSG (especially AHI: Apnea Hypopnea Index)

    Time frame: Baseline
