AI Summary & Key Takeaways
AI InsightSensitivityfor moderate (AHI≥15) and severe OSA (AHI≥30) was identical for both questionnaires.CONCLUSION: The STOP-BANG questionnaire has an excellent sensitivity, but modest specificity and adding national obesity indexesfor neck circumference achieved similar results in terms of sensitivity and specificity with the original questionnaire.

OBJECTIVES: Obstructive sleep apnea (OSA) is a very common sleep-related disorder and has many medical complications. Althoughthe STOP-BANG questionnaire is an attractive screening tool because of high sensitivity, it lacks power in specificity. The aim of thepresent study was to evaluate and compare the diagnostic accuracy of standard STOP-BANG and a modified STOP-BANG questionnaire,using national cut-off values for neck circumference that determined OSA, in a sleep center population.MATERIALS AND METHODS: One hundred eighty-five participants who were referred to the sleep-disordered breathing clinic wereconsecutively enrolled. We used 40 cm and 36 cm as the cut-off values for neck circumference, thus scoring patients accordingly andcreating a modified STOP-BANG score with national anthropometric obesity indexes.RESULTS: The median neck circumferences were 41 (39-44) cm, 40 (37-42) cm, and 43 (40-45) cm for total population, female gender,and male gender, respectively. The mean STOP-BANG score was 4.5±1.5, and the mean modified STOP-BANG score was 4.9±1.5.Discrimination of OSA measured by area under the curve for both questionnaires is comparable (p>0.05). Sensitivity to define OSA(apnea-hypopnea index (AHI)≥5) was 92.2% and 93.8% for original and modified STOP-BANG questionnaire, respectively. Sensitivityfor moderate (AHI≥15) and severe OSA (AHI≥30) was identical for both questionnaires.CONCLUSION: The STOP-BANG questionnaire has an excellent sensitivity, but modest specificity and adding national obesity indexesfor neck circumference achieved similar results in terms of sensitivity and specificity with the original questionnaire.
