背景和目的基于网络的技术对医疗保健的未来至关重要。作为评估慢性肾脏病患者安全性的安全肾脏护理队列研究的一部分，这项研究确定了具有代表性的慢性肾脏病患者或其家人的样本如何有效地解释和使用关于慢性肾脏病安全性的安全肾脏护理网站(www.Safekinneycare.org)。设计、设置、参与者和测量在2011年11月至2012年1月期间，慢性肾脏病患者或他们的家人接受了由一名面试者和另一名录音观察员进行的正式可用性测试。每个参与者都被独立地提供了一份21项要完成的任务的列表，每项任务都被评为容易完成/非关键错误或关键错误(如果没有面试者的显著干预，用户无法完成任务)。所有任务的中位完成时间为17.5分钟(范围为10-44分钟)。总共有10名参与者的严重错误大于或等于一次。在252项任务中，有55项严重错误(22%)，其中当参与者被要求查找可能损害肾脏的治疗信息、在互联网上查找网站、增加字体大小以及滚动到网页底部时，严重错误的比例最高。参与者对网站的内容和可用性总体上感到满意。结论CKD患者的网络教育材料应针对广泛的计算机素养水平，并预期使用计算机和互联网的能力存在差异。临床肾脏病7：1553-1560,2012。DOI：10.2215/CJN.03690412
Background and objectives Web-based technology is critical to the future of healthcare. As part of the Safe Kidney Care cohort study evaluating patient safety in CKD, this study determined how effectively a representative sample of patients with CKD or family members could interpret and use the Safe Kidney Care website (www.safekidneycare.org), an informational website on safety in CKD.Design, setting, participants, & measurements Between November of 2011 and January of 2012, persons with CKD or their family members underwent formal usability testing administered by a single interviewer with a second recording observer. Each participant was independently provided a list of 21 tasks to complete, with each task rated as either easily completed/noncritical error or critical error (user cannot complete the task without significant interviewer intervention).Results Twelve participants completed formal usability testing. Median completion time for all tasks was 17.5 minutes (range=10-44 minutes). In total, 10 participants had greater than or equal to one critical error. There were 55 critical errors in 252 tasks (22%), with the highest proportion of critical errors occurring when participants were asked to find information on treatments that may damage kidneys, find the website on the internet, increase font size, and scroll to the bottom of the webpage. Participants were generally satisfied with the content and usability of the website.Conclusions Web-based educational materials for patients with CKD should target a wide range of computer literacy levels and anticipate variability in competency in use of the computer and internet.
