Obstructive sleep apnea (OSA) is a common, under-recognized, under diagnosed, under treated, and serious medical condition in adults. Polysomnography (PSG) is the gold standard for diagnosis of OSA; however, prohibitive cost of the test and rarity of sleep laboratory in the Arabic nations limit its access. So, searching for another simple, economical, reliable, and valid tool for identification of OSA at risk patients is of special public concern.
This study was conducted to evaluate the reliability and validity of Arabic version of Berlin questionnaire (ABQ) in detection of OSA at risk patients.
After hospital ethics approval and formal patients consent, 100 patients were subjected to full night PSG study after their response to the developed ABQ. The patients were classified into both low (30) and high risk (70) for OSA using ABQ and validated against apnea hypopnea index (AHI). Reliability was assessed by internal consistency using Cronbach's alpha test and consistency over time using test retest correlation.
The study demonstrated a high degree of internal consistency and stability over time for the developed ABQ. The Cronbach's alpha coefficient for the 10-item tool was 0.92. Validation of ABQ against AHI at cutoff >5 revealed a sensitivity of 97%, specificity of 90%, positive and negative predictive values of 96% and 93%, respectively.
The ABQ is reliable and valid scale in screening patients for the risk of OSA among Arabic-speaking nations, especially in resource-limited settings.
阻塞性睡眠呼吸暂停(OSA)是一种常见的、未被充分认识的、诊断不足的、治疗不足的严重医学病症。多导睡眠图(PSG)是 OSA 诊断的金标准;然而,该测试的昂贵成本以及阿拉伯国家睡眠实验室的稀缺性限制了其应用。因此,寻找另一种简单、经济、可靠且有效的工具来识别有风险的 OSA 患者是一个特别的公众关注问题。
本研究旨在评估阿拉伯文柏林问卷(ABQ)在识别有风险的 OSA 患者中的可靠性和有效性。
在获得医院伦理批准和患者正式同意后,100 名患者在对开发的 ABQ 做出反应后接受了整夜 PSG 研究。根据 ABQ 将患者分为低风险(30 例)和高风险(70 例)OSA 患者,并与呼吸暂停低通气指数(AHI)进行验证。通过 Cronbach's alpha 测试评估内部一致性,通过测试-再测试相关性评估一致性。
研究表明,所开发的 ABQ 具有高度的内部一致性和时间稳定性。该 10 项工具的 Cronbach's alpha 系数为 0.92。ABQ 对 AHI>5 的验证显示,其敏感性为 97%,特异性为 90%,阳性预测值和阴性预测值分别为 96%和 93%。
ABQ 是一种可靠且有效的量表,可用于筛查阿拉伯语国家的 OSA 风险患者,特别是在资源有限的环境中。
