Technology is increasingly embedded into the full spectrum of health care. This movement has benefited from the application of software development practices such as usability testing and agile development processes. These practices are frequently applied in both commercial or operational and academic settings. However, the relative importance placed on rapid iteration, validity, reproducibility, generalizability, and efficiency differs between the 2 settings and the needs and objectives of academic versus pragmatic usability evaluations.
This paper explores how usability evaluation typically varies on key dimensions in pragmatic versus academic settings that impact the rapidity, validity, and reproducibility of findings and proposes a hybrid approach aimed at satisfying both pragmatic and academic objectives.
We outline the characteristics of pragmatic versus academically oriented usability testing in health care, describe the tensions and gaps resulting from differing contexts and goals, and present a model of this hybrid process along with 2 case studies of digital development projects in which we demonstrate this integrated approach to usability evaluation.
The case studies presented illustrate design choices characteristic of our hybrid approach to usability evaluation.
Designed to leverage the strengths of both pragmatically and academically focused usability studies, a hybrid approach allows new development projects to efficiently iterate and optimize from usability data as well as preserves the ability of these projects to produce deeper insights via thorough qualitative analysis to inform further tool development and usability research by way of academically focused dissemination.
技术日益融入到医疗保健的各个方面。这一趋势受益于软件开发实践的应用，如可用性测试和敏捷开发流程。这些实践在商业或运营以及学术环境中都经常被应用。然而，在这两种环境中，以及学术性与实用性可用性评估的需求和目标方面，对快速迭代、有效性、可重复性、普遍性和效率的相对重视程度有所不同。
本文探讨了在实用性与学术性环境中，可用性评估在关键维度上通常如何变化，这些维度会影响研究结果的快速性、有效性和可重复性，并提出一种混合方法，旨在同时满足实用性和学术性目标。
我们概述了医疗保健中实用性与学术性导向的可用性测试的特点，描述了不同背景和目标所导致的紧张关系和差距，并展示了这种混合过程的模型以及两个数字开发项目的案例研究，在这些案例中我们展示了这种综合的可用性评估方法。
所展示的案例研究说明了我们混合式可用性评估方法的设计选择特点。
混合方法旨在利用实用性和学术性可用性研究的优势，使新的开发项目能够根据可用性数据高效地进行迭代和优化，同时保留这些项目通过深入的定性分析产生更深刻见解的能力，以便通过学术性传播为进一步的工具开发和可用性研究提供信息。
