本研究的目的是设计和评估一种新型患者门户干预的形成可用性，该干预旨在使糖尿病患者能够启动糖尿病相关监测和预防服务的订单。我们使用以用户为中心的设计冲刺方法来创建我们的干预原型，并通过3轮迭代测试评估其可用性。向参与者（5/轮）展示原型，并要求他们使用有声思维程序执行常见的标准化任务。主持人使用以下量表评定任务绩效：（1）轻松完成，（2）困难完成，（3）失败。参与者完成了系统可用性量表（SUS），得分为0-最差到100-最好。所有测试均通过Zoom远程进行。我们确定了3大类可用性问题：对自动化系统的不信任，内容问题和布局困难。变更包括提高订购过程的清晰度和简化语言;然而，电子健康记录系统固有的设计限制限制了我们对所有可用性问题的响应能力（例如，无法修改布局中的固定元素）。每轮轻松完成任务的百分比分别为67%，60%和80%。平均SUS评分分别为87、74和93。在各轮中，参与者发现干预是有价值的，并赞赏患者主动订购的概念。通过迭代的以用户为中心的设计和测试，我们提高了患者门户干预的可用性。一种使患者能够作为其现有患者门户账户的一部分启动特定疾病服务订单的工具，有可能提高推荐医疗服务的完成率并改善临床结果。
The aim of this study was to design and assess the formative usability of a novel patient portal intervention designed to empower patients with diabetes to initiate orders for diabetes-related monitoring and preventive services. We used a user-centered Design Sprint methodology to create our intervention prototype and assess its usability with 3 rounds of iterative testing. Participants (5/round) were presented with the prototype and asked to perform common, standardized tasks using think-aloud procedures. A facilitator rated task performance using a scale: (1) completed with ease, (2) completed with difficulty, and (3) failed. Participants completed the System Usability Scale (SUS) scored 0—worst to 100—best. All testing occurred remotely via Zoom. We identified 3 main categories of usability issues: distrust about the automated system, content concerns, and layout difficulties. Changes included improving clarity about the ordering process and simplifying language; however, design constraints inherent to the electronic health record system limited our ability to respond to all usability issues (eg, could not modify fixed elements in layout). Percent of tasks completed with ease across each round were 67%, 60%, and 80%, respectively. Average SUS scores were 87, 74, and 93, respectively. Across rounds, participants found the intervention valuable and appreciated the concept of patient-initiated ordering. Through iterative user-centered design and testing, we improved the usability of the patient portal intervention. A tool that empowers patients to initiate orders for disease-specific services as part of their existing patient portal account has potential to enhance the completion of recommended health services and improve clinical outcomes.
