有复杂卫生保健需求的患者需要许多卫生保健提供者的专业知识。沟通、协作和以患者为中心的护理对护理质量和患者预后有积极影响。现有的技术很少能促进提供者之间跨护理环境的协作，并使患者参与其中。我们开发了一个基于网络的临床协作系统Loop来解决这个问题。一个技术系统被接受的可能性与它的易用性和实用性有关。我们让利益相关者参与Loop的概念化和开发，以最大限度地提高其直观性和实用性。本研究旨在报告在Loop可用性测试期间捕获的最终用户对Loop的易用性和有用性的看法。参与者代表三种用户类型（患者、护理人员和卫生保健提供者），从三个人群（癌症患者、青少年和青年癌症患者以及医疗复杂的儿童）中招募。我们在实验室和非现场环境中进行了三个迭代测试和开发周期的可用性测试。我们对可用性测试记录进行了内容分析，以总结和描述参与者对Loop的易用性和有用性的看法。参与者喜欢Loop的测试，并且能够轻松地使用核心功能——撰写、发布和阅读消息。他们在解释某些视觉线索和设计元素或某些功能的目的方面存在困难。这种困难对易用性产生负面影响，但主要局限于辅助功能。参与者预测Loop可以提高护理团队成员之间沟通的效率和有效性；然而，这种感知到的有用性可能会因个人工作流程的中断而受到损害，例如额外的时间或任务需求。Loop被认为具有协作系统的价值；然而，可用性测试结果表明，需要解决一些设计和功能元素，以提高易用性。此外，与会者还强调需要考虑如何实现系统，以最大限度地减少对工作流程的影响并优化有用性。
Patients with complex health care needs require the expertise of many health care providers. Communication, collaboration, and patient-centered care positively impact care quality and patient outcomes. Few technologies exist that facilitate collaboration between providers across settings of care and also engage the patient. We developed a Web-based clinical collaboration system, Loop, to address this gap. The likelihood of a technological system’s uptake is associated with its perceived ease of use and perceived usefulness. We engaged stakeholders in the conceptualization and development of Loop in an effort to maximize its intuitiveness and utility. This study aimed to report end users’ perceptions about the ease of use and usefulness of Loop captured during usability tests of Loop. Participants represented three user types (patients, caregivers, and health care providers) recruited from three populations (adults with cancer, adolescents and young adults with cancer, and children with medical complexity). We conducted usability testing over three iterative cycles of testing and development in both laboratory-based and off-site environments. We performed a content analysis of usability testing transcripts to summarize and describe participant perceptions about the ease of use and usefulness of Loop. Participants enjoyed testing Loop and were able to use the core functions—composing, posting, and reading messages—with little difficulty. They had difficulty interpreting certain visual cues and design elements or the purpose of some features. This difficulty negatively impacted perceived ease of use but was primarily limited to auxiliary features. Participants predicted that Loop could improve the efficiency and effectiveness of communication between care team members; however, this perceived usefulness could be compromised by disruptions to personal workflow such as additional time or task requirements. Loop was perceived to have value as a collaboration system; however, usability testing findings indicate that some design and functional elements need to be addressed to improve ease of use. Additionally, participant concerns highlight the need to consider how a system can be implemented so as to minimize impact on workflow and optimize usefulness.
