背景和简介：远程医疗是使用通信设备远程提供医疗保健的过程，当专门为这一年龄段的人设计时，有可能对老年人群有用。这项研究探索了目前可用的四种视频远程医疗系统的设计，并概述了这些系统在老年人群中影响可用性的问题。材料和方法：采用受试者间实验设计，研究了南卡罗来纳医科大学使用的四种远程医疗系统。这项研究是在当地一家养老院进行的。参与者包括40名60岁或以上的成年人。所使用的相关测量是远程医疗会话和视频会话的平均开始时间、平均错误数、测试后满意度、NASA-任务负载指数(NASA-TLX)工作量测量和IBM-计算机系统可用性问卷测量。对定性数据的分析揭示了几个问题，包括冗长的电子邮件内容、图标放置和聊天框设计，这些问题影响了这些系统在老年人群中的可用性。讨论：建议进行基于人的因素的设计修改，包括简短、准确的电子邮件内容、适当放置的图标和包含说明，以解决定性研究中发现的问题。
Background and Introduction:Telemedicine, the process of providing healthcare remotely using communication devices, has the potential to be useful for the geriatric population when specifically designed for this age group. This study explored the design of four video telemedicine systems currently available and outlined issues with these systems that impact usability among the geriatric population. Based on the results, design suggestions were developed to improve telemedicine systems for this population.Materials and Methods:Using a between-subjects experimental design, the study considered four telemedicine systems used in Medical University of South Carolina. The study was conducted at a local retirement home. The participant pool consisted of 40 adults, 60 years or older. The dependent measures used were the mean times for telemedicine session initiation and video session, mean number of errors, post-test satisfaction ratings, theNASA-Task Load Index (NASA-TLX) workload measures, and the IBM-Computer Systems Usability Questionnaire measures.Results:Statistical significance was found among the telemedicine systems' initiation times. The analysis of the qualitative data revealed several issues, including lengthy e-mail content, icon placement, and chat box design, which affect the usability of these systems for the geriatric population.Discussion:Human factor-based design modifications, including short, precise e-mail content, appropriately placed icons, and the inclusion of instructions, are recommended to address the issues found in the qualitative study.
