Internal and Predictive Validity of Epworth Sleepiness Scale to Evaluate Vigilance of Patient Treated for Obstructive Sleep Apnea Syndrome

Presently, there isn't any international recommendation to evaluate vigilance in Obstructive Sleep Apnea Syndrome. The French Society of Sleep Research and Medicine (SFRMS) recommend evaluating professional driver with a MWT but no recommendation exists for other patients. After a minimal treatment of 4 weeks, the physician has to evaluate the drowsiness risk of these patients using either an objective test like the MWT or a subjective one. In the university hospital Amiens-Picardie, since the 01/01/2015, every patient with an Obstructive Sleep Apnea Syndrome diagnosed by a polysomnography or a ventilatory polygraphy had a MWT after 4 weeks of treatment. At each time of the evaluation, Epworth Sleepiness Scale, tiredness score of Pichot, and depressive score of Beck are performed.
