Screening methods have become increasingly important owing to the growing number of patients suspected of obstructive sleep apnea (OSA) being referred for sleep consultation. The STOP-Bang questionnaire has been validated as a screening tool for OSA in surgical patients.
To evaluate the performance of a Portuguese version of the STOP-Bang questionnaire for the diagnosis of OSA in a sleep clinic.
Prospectively, for 2 months, all patients referred to our clinic for clinical evaluation completed a translated version of the STOP-Bang questionnaire in Portuguese and underwent a sleep study.
We observed 216 patients and 215 (99.5%) were included. Age was 53.63±13.10 years, 63.3% were male patients, neck circumference was 40.4±44.11 cm and BMI was 29.41 [26.85; 33.06] kg/m(2). OSA was present in 78% of the patients, of whom, 33% had moderate and 37% had severe OSA. A STOP-Bang score ≥3 had a sensitivity and positive predictive value (PPV) for OSA of 93.4% and 86.6%, respectively. Each increase in the STOP-Bang score was associated with an increase in the probability of OSA and severe OSA; reaching a 95% OSA probability, for a score of 6, and a 73% severe OSA probability, for a score of 8. A score of 3 and 2 had a negative predictive value for moderate/severe OSA of 85.3% and 91.7%, respectively.
The STOP-Bang questionnaire showed high sensitivity and PPV for OSA with the probability of severe OSA steadily increasing, the higher the scores. Furthermore, a low score showed high predictive value for the exclusion of moderate/severe OSA. The STOP-Bang questionnaire can be a powerful tool for stratifying patients in the diagnosis of OSA.
由于疑似阻塞性睡眠呼吸暂停（OSA）的患者被转介进行睡眠咨询的人数不断增加，筛查方法变得越来越重要。STOP-Bang问卷已被验证为外科手术患者OSA的筛查工具。
评估葡萄牙语版STOP-Bang问卷在睡眠诊所诊断OSA的性能。
前瞻性地，在2个月内，所有转诊至我们诊所进行临床评估的患者均完成了葡萄牙语版的STOP-Bang问卷翻译版，并接受了睡眠研究。
我们观察了216例患者，其中215例（99.5%）被纳入研究。年龄为53.63±13.10岁，男性患者占63.3%，颈围为40.4±44.11cm，体重指数为29.41[26.85；33.06]kg/m²。78%的患者存在OSA，其中33%为中度OSA，37%为重度OSA。STOP-Bang评分≥3对OSA的敏感性和阳性预测值（PPV）分别为93.4%和86.6%。STOP-Bang评分每增加一分，OSA和重度OSA的概率就会增加；评分为6时，OSA概率达到95%，评分为8时，重度OSA概率达到73%。评分为3和2时，对中度/重度OSA的阴性预测值分别为85.3%和91.7%。
STOP-Bang问卷对OSA显示出高敏感性和PPV，随着评分越高，重度OSA的概率稳步增加。此外，低分对排除中度/重度OSA具有较高的预测价值。STOP-Bang问卷可以成为OSA诊断中对患者进行分层的有力工具。
