Delirium is poorly recognised and inadequately treated in medical settings. This research aimed to determine the psychometric properties of a newly developed tool, SQeeC against another emergent instrument, SQiD, in the screening of delirium.
The SQeeC was administered to 100 patients and SQiD administered to their informants in the general medical wards of a General Hospital. Data were compared with the reference standard geriatric consultant assessment of delirium.
Compared with the reference standard, the SQeeC was found to have a sensitivity of 83% (95% CI 52-98%) and a specificity of 81% (95% CI 72-89%) with a negative predictive value of 97% (95% CI 90-100%) while the SQiD was found to have a sensitivity of 77% (95% CI 56-91%), a specificity of 51% (95% CI 37-64%) and a negative predictive value of 83% (95% CI 66-93%).
The SQeeC and SQiD are simple and time efficient screening tools with encouraging psychometric properties.
在医疗环境中，谵妄常未得到充分识别和治疗。本研究旨在确定一种新开发的工具SQeeC与另一种新兴工具SQ iD在谵妄筛查中的心理测量特性。
在一家综合医院的普通内科病房，对100名患者使用SQeeC进行评估，并对其信息提供者使用SQ iD进行评估。将数据与谵妄的参考标准老年科医生评估结果进行比较。
与参考标准相比，发现SQeeC的灵敏度为83%（95%置信区间52 - 98%），特异度为81%（95%置信区间72 - 89%），阴性预测值为97%（95%置信区间90 - 100%）；而SQ iD的灵敏度为77%（95%置信区间56 - 91%），特异度为51%（95%置信区间37 - 64%），阴性预测值为83%（95%置信区间66 - 93%）。
SQeeC和SQ iD是简单且省时的筛查工具，其心理测量特性令人鼓舞。
