The diagnosis of neurocognitive diseases is an important health issue for patients, families and healthcare professionals. The need to develop rapid, high-performance screening tools would improve access to care. The Clock Drawing Test (CDT) is widely used and validated with the older adults, and its digital version is becoming increasingly widespread. We propose to confirm its validity in a population of old patients hospitalized in a geriatric unit, and secondly to verify its performance in comparison with the reference diagnosis made by a specialized team in a memory consultation. CDTs were collected from older hospitalized patients, both in paper form and digitally on a touchscreen tablet. The results show good agreement between the paper and digital versions (kappa coefficient = 0.81). Sensitivity and specificity of the digital CDT were 0.84 and 0.59 respectively for the diagnosis of major cognitive disorders. The corresponding values were 0.72 and 0.59 for the diagnosis of mild neurocognitive disorders. User questionnaires indicate that older participants find the digital tablet easy to use. However, they prefer to use paper, even if they are open to learning how to use the tablet.
神经认知疾病的诊断是患者、家庭和医疗保健专业人员的一个重要健康问题。开发快速、高性能的筛选工具的需求将改善获得护理的机会。画钟测验（CDT）在老年人中被广泛使用和验证，其数字化版本也越来越普及。我们建议在老年患者住院的老年病房中确认其有效性，并其次与专门的记忆咨询团队做出的参考诊断进行性能比较。CDT 从住院的老年患者中收集，无论是纸质形式还是在触摸屏平板电脑上的数字形式。结果表明，纸质版和数字版之间具有良好的一致性（kappa 系数=0.81）。数字 CDT 对主要认知障碍的诊断具有 0.84 的敏感性和 0.59 的特异性。对于轻度神经认知障碍的诊断，相应的值分别为 0.72 和 0.59。用户问卷表明，年长的参与者认为数字平板电脑易于使用。然而，他们更喜欢使用纸张，即使他们愿意学习如何使用平板电脑。
