The increasing prevalence and burden of chronic obstructive pulmonary disorder (COPD), the challenges in implementing pulmonary rehabilitation (PR) programs and the limited availability of alternatives and supportive programs to serve patients with COPD necessitate the development of pulmonary telerehabilitation (PTR) systems to provide patients with COPD with PR programs.
This study aimed to design and develop the ChestCare mobile Health app using user-centred design (UCD) approach. Thus, it provided PTR for patients with COPD, enhancing their self-management of symptoms and improving their compliance with PR programs.
In this mixed-methods sequential research, we deployed the UCD iterative design through the prototype app design and development sequence. The first phase was built based on the results of a previous needs assessment study and an analysis of related apps. This produced the initial mock-up, the foundation for the focus group discussions with physiotherapists and patients. Six physiotherapists with cardiorespiratory specialisation evaluated each app module and item of the latest mock-up using the content validity index (CVI) document. The I-CVI (S-CVI/Ave) and (S-CVI/UA) were computed. Qualitative and quantitative data were integrated, and decisions were made by comparing their results.
The UCD iterative design through sequential MMR has generated four mock-up app versions. The latest version identified 13 modules through 150 items validated by six experts using a CVI document. The I-CVI calculation of 145 items was 1, while 0.83 for the remaining items, was within accepted values. The S-CVI scored 99.4, indicating an overall validity of the ChestCare app as a PTR system for patients with COPD.
The development and validation of the ChestCare app resulted from conducting UCD iterative design and sequential MMR, which identified 13 functionalities, including symptom assessment, tracking lung volume, functional capacity test, action plan, intervention program, COPD education, COPD community, monitoring and reminders.
慢性阻塞性肺疾病（COPD）的患病率和负担日益增加，实施肺康复（PR）计划面临挑战，且为COPD患者提供服务的替代方案和支持计划有限，因此有必要开发肺远程康复（PTR）系统，为COPD患者提供PR计划。
本研究旨在采用以用户为中心的设计（UCD）方法设计和开发ChestCare移动健康应用程序。从而为COPD患者提供PTR，增强他们对症状的自我管理，并提高他们对PR计划的依从性。
在这项混合方法的序列研究中，我们通过原型应用程序设计和开发序列部署了UCD迭代设计。第一阶段基于先前需求评估研究的结果和对相关应用程序的分析构建。这产生了初始模型，作为与物理治疗师和患者进行焦点小组讨论的基础。六名具有心肺专业的物理治疗师使用内容效度指数（CVI）文件评估了最新模型的每个应用程序模块和项目。计算了I-CVI（S-CVI/Ave）和（S-CVI/UA）。整合了定性和定量数据，并通过比较结果做出决策。
通过序列混合方法研究进行的UCD迭代设计产生了四个应用程序模型版本。最新版本通过150个项目确定了13个模块，这些项目由六名专家使用CVI文件进行了验证。145个项目的I-CVI计算结果为1，其余项目为0.83，均在可接受值范围内。S-CVI得分为99.4，表明ChestCare应用程序作为COPD患者的PTR系统具有整体有效性。
ChestCare应用程序的开发和验证源于进行UCD迭代设计和序列混合方法研究，该研究确定了13项功能，包括症状评估、跟踪肺容量、功能能力测试、行动计划、干预计划、COPD教育、COPD社区、监测和提醒。
