背景：移动医疗（mHealth）具有改善医疗服务可及性的潜力，特别是在发展中国家。移动医疗的普及并没有伴随着移动医疗应用程序设计指南的相应增长。本文提出了一种结合信息系统研究（ISR）框架和设计思维的移动医疗应用程序设计框架。我们以应用程序的形式展示了拟议框架的一个用例，用于读取结核菌素皮肤试验（TST）的结果，TST用于筛查潜伏性结核感染。该框架用于重新设计TST阅读应用程序，但也可以用于移动健康应用程序设计的早期阶段。方法基于设计思维模式与ISR框架周期的融合，将ISR框架与设计思维进行融合。使用组合框架，我们重新设计了一款用于TST阅读的移动健康应用程序，旨在主要供医疗工作者在发展中环境中使用。使用提议的框架，应用程序在人物角色、观察、原型和问卷的帮助下进行了迭代和开发。结果通过与最终用户（10名医护人员和10名研究生）的接触，应用了组合框架。通过回顾文献和应用原型的迭代，我们确定了各种可用性需求和限制。这些挑战包括与图像捕获和对指令的误解有关的挑战。这些见解影响了应用程序的开发和改进。综合框架可以与终端用户互动，在解决环境挑战和需求的同时，实现低成本、快速的应用开发。设计思维模式与ISR周期的整合有效地实现了每种方法的目标。综合框架承认在实施移动医疗技术时吸引用户的重要性，特别是在发展中国家和资源不足的情况下。本研究的结果支持使用该框架作为设计以用户为中心的移动健康干预措施的指南。
Background Mobile health (mHealth) has the potential to improve access to healthcare, especially in developing countries. The proliferation of mHealth has not been accompanied by a corresponding growth in design guidelines for mHealth applications. This paper proposes a framework for mHealth application design that combines the Information Systems Research (ISR) framework and design thinking. We demonstrate a use case for the proposed framework in the form of an app to read the result of the tuberculin skin test (TST), which is used to screen for latent tuberculosis infection. The framework was used in the re-design of the TST reading app but could also be used in earlier stages of mHealth app design. Methods The ISR framework and design thinking were merged based on how the modes of design thinking integrate with the cycles of the ISR framework. Using the combined framework, we re-designed an mHealth app for TST reading, intended to be used primarily in a developing context by healthcare workers. Using the proposed framework, the app was iterated upon and developed with the aid of personas, observations, prototyping and questionnaires. Result The combined framework was applied through engagement with end-users, namely ten healthcare workers and ten graduate students. Through review of the literature and iterations of the app prototype, we identified various usability requirements and limitations. These included challenges related to image capture and a misunderstanding of instructions. These insights influenced the development and improvement of the app. Conclusion The combined framework allowed for engagement with end-users and for low-cost, rapid development of the app while addressing contextual challenges and needs. The integration of design thinking modes with the ISR cycles was effective in achieving the objectives of each approach. The combined framework acknowledges the importance of engaging users when implementing mHealth technologies, especially in developing and under-resourced contexts. Findings from this study support the use of this framework as a guide in the design of user-centred mHealth interventions.
