As a superiority to conventional statistical models, grey models require only a limited amount of data to estimate the behaviour of unknown systems. Grey system theory can be used in the effective factor assessment, and used in large samples where data are not available or uncertain whether the data was representative. Therefore, the purpose of this study was to adopt grey system theory to discuss older adult users' opinions on the telecare and its effect on their quality of life. This study surveyed the older adult users of Taiwan as subjects. User perception of the telecare services was collected via face-to-face interview. The grey system theory was used to examine the model. The results showed that the overall living quality has the greatest effect on the perceived effects of the telecare on their quality of life, followed by the acquisition of information, accessibility of medical care services, and safety. This finding may serve as a reference to future studies and it also shows that the grey system theory is a feasible analysis method.
与传统的统计模型相比，灰色模型只需要有限的数据就可以估计未知系统的行为。灰色系统理论可用于有效因素评估，并可用于数据不可用或不确定数据是否具有代表性的大样本中。因此，本研究旨在采用灰色系统理论探讨老年用户对远程医疗的看法及其对生活质量的影响。本研究以台湾的老年用户为研究对象。通过面对面访谈收集用户对远程医疗服务的感知。使用灰色系统理论来检验模型。结果表明，整体生活质量对远程医疗对生活质量的感知效果影响最大，其次是信息获取、医疗服务的可及性和安全性。这一发现可为未来的研究提供参考，也表明灰色系统理论是一种可行的分析方法。
