    UnlabelledFor an adequate analysis of sleep quality was assessed a new composed index wich objectively approached variate polisomnographic parameters. We used this new concept--sleep disturbances index-SDI in patients with obstructive sleep apnea (OSAS), before and after the beginning of CPAP therapy.Material And Method41 patients were evaluated and for each one we calculated SDI score. All patients were split in two groups according with apnea-hipopnea index (AHI), and we correlated SDI with AHI as marker of severity of the disease and with Epworth Sleepiness Scale's scores, as an subjective evaluation. After 1 month of CPAP therapy, SDI was reevaluated.ResultsSDI is correlating with the severity of the disease: for group 1, with 5 < AHI < 15, SDI= 2.24 +/- 0.88, r = 0.53, p < 0.01 and for group 2, with AHI >15, SDI = 3.23 +/- 0.69, p < 0.01, r = 0.46. There was no significant correlation between SDI and ESS scores (r = 0.23, p < 0.01). SDI lowers significant during CPAP therapy: SDI= 1.48 +/- 0.60, respectiv SDI = 1.90 +/- 1.23.ConclusionThe severity of OSAS is correlated with increased SDI, but can be seen interindividual variability. The effect of CPAP therapy is reflecting also in sleep quality.
