Abstract：
To develop and validate a simple questionnaire for the diagnosis of Benign Paroxysmal Positional Vertigo (BPPV) and also to accurately predict the involved side in BPPV. Patients (N = 148) who presented with dizziness to the ENT department were asked to fill out a questionnaire which was formulated to diagnose BPPV and the affected side. Five questions were part of the questionnaire. The fifth question was set to ascertain the affected side in BPPV. All the patients underwent a detailed neuro-otological examination and the findings were noted. The findings of the examination were correlated with the questionnaire findings. The mean age of the patient group was 54.72 years of age. The sensitivity of the questionnaire in detecting BPPV was 94.5%, though in 12.79% (n = 11) the side was not predicted correctly. The specificity of the questionnaire was 91.22%. The positive predictive value of the questionnaire in detecting BPPV was assessed at 94.5%.The questionnaire can be effectively used in predicting BPPV amongst patients presenting with dizziness and thus helps in avoiding unnecessary imaging and referrals to higher centres in view of suspicion of central causes of dizziness.
摘要：
开发并验证用于诊断良性阵发性位置性眩晕（BPPV）的简单问卷，并准确预测BPPV的受累侧。要求在ENT部门出现头晕的患者（N=148）填写一份调查表，该调查表旨在诊断BPPV和受影响的一侧。问卷中有五个问题。第五个问题是为了确定BPPV中受影响的一侧。所有患者均接受了详细的神经耳科检查，并记录了发现。检查结果与问卷结果相关。患者组的平均年龄为54.72岁。问卷检测BPPV的敏感性为94.5%,尽管在12.79%(n=11)中，该方预测不正确。问卷的特异性为91.22%。问卷在检测BPPV方面的阳性预测值被评估为94.5%。该问卷可有效地用于预测头晕患者的BPPV，从而有助于避免不必要的成像和转诊到更高的中心，因为怀疑头晕的中心原因。
