A personal health record is an eHealth technology in which users can observe their progress over time for a given condition. A research gap was identified in the literature concerning the study of the amount of energy that these systems need for their operation, and the energy efficiency that may be attained depending on their design. After the selection of five representative personal health records, a total of 20 tasks commonly done, and based on previous work, were performed with regard to two proposed scenarios, namely patient use and health personnel usage. The power consumption of the main components of a host machine was measured during the performance of the proposed duties. To that end, a hardware tool called the Energy Efficiency Tester was employed. The data collected were analyzed statistically, and significant differences were found in the respective consumption of the display (χ (4) = 23.782, p = 0.000), the processor (χ (4) = 29.018, p = 0.000) and the whole PC (χ (4) = 28.582, p = 0.000). For all of these components, NoMoreClipBoard was the personal health record that required the least energy (57.699 W for the display, 3.162 W for the processor and 181.113 W for the whole PC). A total of two strong correlations were found in the energy consumption between the hard disk and the graphics card (r = 0.791, p < 0.001), and the processor and the PC (r = 0.950, p < 0.001). Some features generated special amounts of power consumption, such as the news wall found on PatientsLikeMe, or the use of load icons that had an impact on most PC components. In addition, an in-depth analysis of the user interfaces was performed. A discussion was carried out on the design of the user interfaces, also taking into account recommendations drawn from the literature, checking for their implementation in the personal health records selected. With the aim of promoting sustainability among software developers, a best practice guideline on sustainable software design was proposed. Basic sustainability recommendations were collected for professionals to consider when developing a software system in general, and a personal health record in particular.
个人健康记录是一种电子健康技术，用户可以通过它观察自身在特定病情下随时间的进展情况。文献中发现了一个研究空白，即关于这些系统运行所需能量以及根据其设计可能实现的能源效率的研究。在挑选出五份具有代表性的个人健康记录后，针对患者使用和医护人员使用这两种拟议场景，基于先前的工作，总共执行了20项常见任务。在执行这些任务期间，测量了主机主要组件的功耗。为此，使用了一种名为能源效率测试仪的硬件工具。对收集到的数据进行了统计分析，发现显示器（χ(4)=23.782，p=0.000）、处理器（χ(4)=29.018，p=0.000）以及整个个人电脑（χ(4)=28.582，p=0.000）各自的功耗存在显著差异。对于所有这些组件，NoMoreClipBoard是所需能量最少的个人健康记录（显示器为57.699瓦，处理器为3.162瓦，整个个人电脑为181.113瓦）。在硬盘与显卡之间的能耗（r=0.791，p<0.001）以及处理器与个人电脑之间的能耗（r=0.950，p<0.001）中总共发现了两个强相关性。一些功能会产生特殊的功耗量，比如PatientsLikeMe上的新闻墙，或者对大多数个人电脑组件有影响的加载图标使用情况。此外，还对用户界面进行了深入分析。结合从文献中得出的建议，对用户界面的设计进行了讨论，并检查了在所选个人健康记录中的实施情况。为促进软件开发人员的可持续性，提出了一份关于可持续软件设计的最佳实践指南。收集了基本的可持续性建议，供专业人员在一般开发软件系统，特别是开发个人健康记录时参考。
