ABSTRACT
OBJECTIVE To evaluate the value of Epworth sleepiness scale(ESS) combined with home-based portable monitoring(PM) in the diagnosis of patients with obstructive sleep apnea syndrome(OSAS). METHODS Adult OSAS patients who visited Beijing Tongren Hospital and complained of snoring were included in this study. The overnight polysomnography(PSG) and the ESS were completed at the sleep center and the portable multi-channel monitoring was completed within one week. Subjects were divided into two groups according to their apnea hypopnea index(AHI) of PSG simple snoring or mild OSAS group(AHI<15/h) and moderate-severe group(AHI≥15/h). The ESS score, respiratory disturbance index(RDI) of PM and other parameters were compared and the correlation of AHI with ESS scores, RDI were analyzed. The sensitivity and specificity of ESS score≥9 points, RDI≥15/h in the diagnosis of moderate-severe OSAS were calculated. RESULTS A total of 51 subjects were included in this study with 42 males(82.4%) and 9 females(17.6%). Mean age was(43.8±10.8) years, and the mean body mass index was(27.9±4.5)kg/m2; ESS scored 1-24 points and mean(8.6±5.0) points, 18 cases with ESS score ≥9 points; AHI ranged between 2.5 and 99.8/h with a mean of(37.4±29.8)/h. There were 19(37.3%) and 32(62.7%) patients in snoring-mild group and moderate-severe group, respectively. There was significant difference for ESS scores between the two groups(9.9±5.1 vs 6.6±4.2 points, P<0.05),RDI in moderate-severe OSAS group was significantly higher than that in snoring-mild group[(49.4±23.1)/h vs (6.8±4.5)/h, P<0.001)]. There was a positive correlation between the ESS score and PSG derived AHI(r =0.435, P =0.002); the PM derived RDI were significantly correlated with PSG derived AHI in snoring-mild group(r =0.706, P=0.001), moderate-severe group(r =0.873, P=0.000) and patients with ESS score ≥9 points(r =0.967, P=0.000). At a PSG threshold AHI=15/h, the sensitivity and specificity for ESS score ≥9 points were 45.2% and 78.9%; the PM derived RDI≥15/h had a sensitivity and specificity of 84.4% and 84.2%, respectively; the sensitivity and specificity for each individual screening tool along with the combination of ESS and PM were 100.0% and 100.0%. CONCLUSION ESS combined with PM diagnostic method is a valuable measure for the diagnosis of moderate and severe OSAS patients.
