Descriptive and transversal study to evaluate the performance of CAGE among psychiatric outpatients at a tertiary-level university hospital. Convenience sample composed of patients from HCFMRP-USP (n=127). The instruments used were CAGE and the diagnostic interview based on ICD-10 criteria for harmful use and alcohol dependence. The performance of CAGE scores was evaluated through the analysis of ROC curve, using the ICD-10 clinical diagnostic as a gold standard. The sensitivity and specificity in accordance with the cut-off points are: > or =0, Sens=100%, Spec=0%; > or =1, Sens=100%, Spec=73.7%; > or =2, Sens=53.8%, Spec=87.7%; > or =3, Sens=53.8%, Spec=94.7%; > or =4, Sens=0%; Spec=100%. Score 1 showed to be the ideal critical point for sensibility/specificity. > or =1 was the best cut-off point for CAGE among psychiatric outpatients from a tertiary-level university hospital. To increase the diagnostic power of the test and the reliability of its results, its performance in the study population should be assessed.
一项描述性横断面研究，旨在评估CAGE量表在一所三级大学医院精神科门诊患者中的表现。便利样本由来自圣保罗大学医学院医院（HCFMRP-USP）的患者组成（n = 127）。所使用的工具为CAGE量表以及基于国际疾病分类第十版（ICD-10）有害使用和酒精依赖标准的诊断访谈。以ICD-10临床诊断作为金标准，通过分析ROC曲线来评估CAGE评分的表现。根据截断点得出的敏感性和特异性如下：≥0，敏感性 = 100%，特异性 = 0%；≥1，敏感性 = 100%，特异性 = 73.7%；≥2，敏感性 = 53.8%，特异性 = 87.7%；≥3，敏感性 = 53.8%，特异性 = 94.7%；≥4，敏感性 = 0%；特异性 = 100%。分数1显示为敏感性/特异性的理想临界点。≥1是该三级大学医院精神科门诊患者中CAGE量表的最佳截断点。为提高测试的诊断能力及其结果的可靠性，应评估其在研究人群中的表现。
