Abstract:
Around 339 million people worldwide have asthma, and 50% have uncontrolled asthma. One trait of uncontrolled asthma, often seen in primary care, is short-acting β2-agonist (SABA) overuse, defined as using SABA more than twice a week. SABA overuse can cause adverse health effects. An application could help patients gain more insight into their SABA use. Engaging stakeholders during the development is important to maximize the usability of and adherence to an application. This study describes the development process of an application that promotes responsible SABA use in people with asthma, using a participatory design. Different stakeholder groups were involved in two iterative development cycles. In the first cycle, four end-users evaluated the app\'s prototype. During the second cycle, five end-users were interviewed about the usability of the new version. Resulting in an app that allows patients to register SABA use, asthma symptoms, and symptom triggers. A graph shows how these factors are related, and end-users can show the graph to their physician to facilitate communication. Medication use is compared to the medical guidelines or, when applicable, to the advice given by the users\' healthcare professionals. End-users found the app helpful. Research into the usability and effectiveness of the app in a bigger sample will follow.
摘要:
全球约有3.39亿人患有哮喘,50%的人患有不受控制的哮喘。哮喘失控的一个特征,经常出现在初级保健中,是短效β2激动剂(SABA)的过度使用,定义为每周使用SABA超过两次。SABA过度使用会对健康造成不良影响。应用程序可以帮助患者更深入地了解SABA的使用情况。在开发过程中让利益相关者参与对于最大限度地提高应用程序的可用性和一致性非常重要。这项研究描述了在哮喘患者中促进负责任的SABA使用的应用程序的开发过程,使用参与式设计。不同的利益相关者群体参与了两个迭代开发周期。在第一个周期中,四个最终用户评估了应用程序的原型。在第二个周期中,就新版本的可用性采访了五名最终用户。导致一个应用程序,允许患者注册SABA使用,哮喘症状,和症状触发因素。图表显示了这些因素是如何相关的,和最终用户可以显示图形给他们的医生,以促进沟通。药物使用与医学指南相比,或者,适用时,向用户的医疗保健专业人员提供的建议。最终用户发现该应用程序很有用。接下来将在更大的样本中研究应用程序的可用性和有效性。
