The Value Of The STOP-Bang Questionnaire In Screening OSAHS In Sleep Disordered Breathing Clinic

Objective:Evaluating the value of the STOP-Bang questionnaire in screening OSAHS in sleep disordered breathing clinic to further apply in general populationMethod212patients undergoing diagnostic overnight PSG in the sleep disordered breathing clinic of Pecking Union Medical College Hospital between May2011and January2012were prospectively included in this study. They were asked to fill in the STOP-Bang questionnaires. A score of3or more was taken to indicate high risk for presence of OSAHS. These were then evaluated versus results from the overnight, monitored PSG, and analysis the relationship of STOP-Bang questionnaire and PSG, the sensitivity and specificity of STOP-Bang questionnaire in screening OSAHS. Logistic regression analysis was used to predict the severity of OSAHS based upon the AHI.ResultsUsing STOP-Bang questionnaire to stratify the patients in sleep disorder breathing clinic, compared to the OSAHS at low risk, the OSAHS at high risk had higher AHI, ODI and the ratio of SpO2lower than90%, lower LSpO2during sleep and less stage3of sleep time. STOP-Bang questionnaire scores were positive correlation with AHI, ODI and the ratio of SpO2lower than90%, and negative correlation with LSpO2during sleep. The sensitivities of the STOP questionnaire with AHI≤5/h, AHI≤15/h,AHI≤30/h as cut-offs were94.9%,96.5%and97.7%, respectively, and the specificities were50.0%,28.6%and17.9%, respectively. The logistic regression analysis showed a progressive increase in the probability of severe (4.3%to97.0%) and progressive decrease in the probability of none (65.0%to0.3%).ConclusionsThe STOP-Bang questionnaire is a concise and easy-to-use screening tool for OSAHS. It has excellent sensitivity in sleep disordered breathing clinic and can predict the severity of OSAHS. Its value in screening OSAHS in general population need further research. Objective:Evaluating the value of the STOP-Bang questionnaire in screening OSAHS in sleep disordered breathing clinic by comparing with the Epworth sleepiness scales, Berlin questionnaire and STOP questionnaire to further apply in general populationMethod212patients undergoing diagnostic overnight PSG at the sleep disordered breathing clinic of Pecking Union Medical College Hospital in between May2011and January2012were prospectively included in this study. They were asked to fill in a STOP-Bang questionnaire, Epworth sleepiness scales, Berlin questionnaire and STOP questionnaire before undergoing overnight PSG. Using PSG as gold standard, The sensitivities, specificities of STOP-Bang questionnaire, Epworth sleepiness scales, Berlin questionnaire and STOP questionnaire were compared. According to the cut-offs of every questionnaires, the population was classified into high risk and low risk, then the clinic condition and characteristic of PSG were compared.ResultsThe value of ESS in screening OSAHS was limited, and cannot identify mild and moderate OSAHS. Berlin questionnaire, STOP questionnaire and STOP-Bang questionnaire had favorable sensitivities, and STOP-Bang had the highest sensitivities and area under ROC curve. The sensitivities of the STOP questionnaire with AHI≥5/h, AHI≥15/h, AHI≥30/h as cut-offs were94.9%,96.5%, and97.7%, respectively; the specificity were50.0%,28.6%and17.9%, respectively; the area under ROC curve were0.815,0.746and0.751respectively. According to STOP-Bang questionnaire, the population was classified into high risk group and low risk group. The gender, BMI, neck circumference, AHI,ODI, LSpO2, the cases of AHI≥5/h、the cases of AHI≥15/h and the cases of AHI≥30/h of these two groups were significant different.ConclusionsThe STOP-Bang questionnaire is a concise and easy-to-use screening tool for OSAHS. It has excellent sesitivity in sleep disordered breathing clinic and has the highest sensitivity when comparing to ESS, Berlin questionnaire and STOP questionnaire. It should be further used in screening OSAHS in general population.
