Nowadays, elderly patients represent a significant number of accesses to the Emergency Department (ED). Working rhythms do not allow to perform complete cognitive analysis, which would, however, be useful for the health care. This study aims to define the optimal cut-off values of the six-item Cognitive Impairment Test (6-CIT) as a cognitive screening tool in ED.
This study included 215 subjects, evaluated at the Emergency Department of the University Hospital of Monserrato, Cagliari, Italy, from July to December 2021. The accuracy of 6-CIT as a cognitive screening tool was assessed by comparison with Mini Mental State Examination (MMSE).
The correlation coefficient between the two tests was -0.836 (CI: -0.87 to -0.79; < 0.0001), and 6-CIT showed AUC = 0.947 (CI: 0.908-0.973; < 0.0001). The 8/9 6-CIT cut-off score presented 86.76% sensitivity (CI: 76.4-93.8) and 91.84% specificity (CI: 86.2-95.7), and Youden index for this score was 0.786.
Our study demonstrates that 6-CIT is a reliable cognitive screening tool in ED, offering excellent sensitivity and specificity with a 8/9 points cut-off score.
如今，老年患者占急诊室（ED）就诊人数的很大一部分。工作节奏不允许进行全面的认知分析，然而，这对医疗保健是有用的。本研究旨在确定六项认知障碍测试（6-CIT）作为急诊室认知筛查工具的最佳临界值。
本研究纳入了215名受试者，于2021年7月至12月在意大利卡利亚里蒙塞拉托大学医院急诊室进行评估。通过与简易精神状态检查表（MMSE）比较，评估6-CIT作为认知筛查工具的准确性。
两项测试之间的相关系数为-0.836（CI：-0.87至-0.79；<0.0001），6-CIT的AUC为0.947（CI：0.908-0.973；<0.0001）。6-CIT的8/9临界值分数的灵敏度为86.76%（CI：76.4-93.8），特异度为91.84%（CI：86.2-95.7），该分数的约登指数为0.786。
我们的研究表明，6-CIT是急诊室可靠的认知筛查工具，8/9分的临界值分数具有出色的灵敏度和特异度。
