Evaluation And Comparison Of Three OSAHS Screening Tools In Outpatient Snoring Female

Background Obstructive sleep apnea(OSA)is a common chronic disease required lifelong treatment.Among women snorers,the prevalence of OSA is as high as 15.2%.However,the missed diagnosis rate of OSA in women is more than 90%.So it is necessary to find screening tools with better screening value.Among the questionnaires that are commonly used for obstructive sleep apnoea screening,it remains unclear which one is more effective in terms of ease of use and diagnosis of female snores with obstructive sleep apnoea risk.Objective To validate and compare the OSAHS screening model of female snorers,NoASA score and STOP-BANG questionnaire among outpatient snoring women..Methods To recruite 260 outpatient snoring women who underwent a polysomnography(PSG)from March 2018 to January 2019,in two tertiary first-class hospitals in Beijing.Three questionnaires were completed.The screening value of the three screening tools was analyzed which based on the severity of OSA,determined by apnea-hypopnea index(AHI).The area under curve(AUC)of the receiver operating characteristics of three questionnaires were calculated to judge the most suitable screening tools for outpatient snoring women.Results AHI>/=5 events/h,the scores of the three screening tools were related to the diagnosis(P<0.05).The score of the OSAHS screening model of female snorers was 7(4,10).The AUC of the screening model was 0.769(95%CI:0.711,0.828),which was moderate predictive value.The Youden Index of 6 score was a maximum(0.437),and the AUC,sensitivity and specificity of 6 score were 0.719,75.3%,68.4%,respectively,higher than those of 7 score.NoASA score was 6(2,9),and the AUC of NoASA score was 0.654(95%CI:0.588,0.722),which was low predictive value.The Youden Index of 5 score was a maximum(0.236),and the AUC,sensitivity and specificity of 5 score were 0.618,81.5%,42.1%.AUC and sensitivity were higher than those of 7 score.The score of STOP-BANG questionnaire was 3(2,5).The AUC of STOP-BANG questionnaire was 0.782(95%CI:0.726,0.838),which had moderate predictive value for OSA.The Youden Index of 4 score was a maximum(0,439).The AUC,sensitivity and specificity of 4 score were 0.720、68.5%、75.4%,higher than that of 3 score.Compared with the AUC of the three screening tools,the AUC of STOP-BANG and female OSAHS screening model had no difference.Conclusion The OSAHS screening model of female snorers and STOP-BANG questionnaire have moderate predictive value for OSA,while NoSAS score has low predictive value.After adjusting the cut-off value,the sensitivity of the OSAHS screening model of female snorers is higher when the cut-off value is 6.which can improve the detection rate of snoring OSA women,and it is expected to be further promoted to the community.
