Sickle cell disease (SCD) is a hematological genetic disease affecting over 25 million people worldwide. The main clinical manifestations of SCD, hemolytic anemia and vaso-occlusion, lead to chronic pain and organ damages. With recent advances in childhood care, high-income countries have seen SCD drift from a disease of early childhood mortality to a neglected chronic disease of adulthood. In particular, coordinated, preventive, and comprehensive care for adults with SCD is largely underresourced. Consequently, patients are left to self-manage. Mobile health (mHealth) apps for chronic disease self-management are now flooding app stores. However, evidence remains unclear about their effectiveness, and the literature indicates low user engagement and poor adoption rates. Finally, few apps have been developed for people with SCD and none encompasses their numerous and complex self-care management needs.
This study aimed to identify factors that may influence the long-term engagement and user adoption of mHealth among the particularly isolated community of adult patients with SCD living in low-prevalence, high-income countries.
Semistructured interviews were conducted. Interviews were audiotaped, transcribed verbatim, and analyzed using thematic analysis. Analysis was informed by the Braun and Clarke framework and mapped to the COM-B model (capability, opportunity, motivation, and behavior). Results were classified into high-level functional requirements (FRs) and nonfunctional requirements (NFRs) to guide the development of future mHealth interventions.
Overall, 6 males and 4 females were interviewed (aged between 21 and 55 years). Thirty FRs and 31 NFRs were extracted from the analysis. Most participants (8/10) were concerned about increasing their physical capabilities being able to stop pain symptoms quickly. Regarding the psychological capability aspects, all interviewees desired to receive trustworthy feedback on their self-care management practices. About their physical opportunities, most (7/10) expressed a strong desire to receive alerts when they would reach their own physiological limitations (ie, during physical activity). Concerning social opportunity, most (9/10) reported wanting to learn about the self-care practices of other patients. Relating to motivational aspects, many interviewees (6/10) stressed their need to learn how to avoid the symptoms and live as normal a life as possible. Finally, NFRs included inconspicuousness and customizability of user experience, automatic data collection, data shareability, and data privacy.
Our findings suggest that motivation and engagement with mHealth technologies among the studied population could be increased by providing features that clearly benefit them. Self-management support and self-care decision aid are patients' major demands. As the complexity of SCD self-management requires a high cognitive load, pervasive health technologies such as wearable sensors, implantable devices, or inconspicuous conversational user interfaces should be explored to ease it. Some of the required technologies already exist but must be integrated, bundled, adapted, or improved to meet the specific needs of people with SCD.
镰状细胞病(SCD)是一种血液学遗传疾病,全球有超过2500万人受其影响。SCD的主要临床表现为溶血性贫血和血管阻塞,会导致慢性疼痛和器官损害。随着儿童护理方面的最新进展,高收入国家的SCD已从一种儿童早期死亡率高的疾病转变为一种被忽视的成人慢性病。特别是,针对成年SCD患者的协调、预防和综合护理在很大程度上资源不足。因此,患者只能自行管理。用于慢性病自我管理的移动健康(mHealth)应用程序如今充斥着应用商店。然而,关于其有效性的证据仍不明确,而且文献表明用户参与度低且采用率不佳。最后,针对SCD患者开发的应用程序很少,且没有一款能满足他们众多且复杂的自我护理管理需求。
本研究旨在确定可能影响生活在低患病率高收入国家的特别孤立的成年SCD患者群体对mHealth长期参与度和用户采用率的因素。
进行了半结构化访谈。访谈进行了录音,逐字转录,并采用主题分析法进行分析。分析以布劳恩和克拉克框架为依据,并映射到COM-B模型(能力、机会、动机和行为)。结果被分类为高级功能需求(FRs)和非功能需求(NFRs),以指导未来mHealth干预措施的开发。
总体而言,共访谈了6名男性和4名女性(年龄在21至55岁之间)。分析中提取了30项功能需求和31项非功能需求。大多数参与者(8/10)关心增强自身身体能力,即能够迅速止住疼痛症状。在心理能力方面,所有受访者都希望在自我护理管理实践中得到可靠的反馈。关于身体机会,大多数人(7/10)表示非常希望在达到自身生理极限时(如在体育活动期间)收到提醒。在社会机会方面,大多数人(9/10)报告称希望了解其他患者的自我护理实践。在动机方面,许多受访者(6/10)强调他们需要学习如何避免症状并尽可能正常地生活。最后,非功能需求包括用户体验的不显眼性和可定制性、自动数据收集、数据可共享性和数据隐私。
我们的研究结果表明,通过提供明显对他们有益的功能,可以提高研究人群对mHealth技术的动机和参与度。自我管理支持和自我护理决策辅助是患者的主要需求。由于SCD自我管理的复杂性需要较高的认知负荷,应探索诸如可穿戴传感器、植入式设备或不显眼的对话式用户界面等普及型健康技术来缓解这一问题。一些所需技术已经存在,但必须进行整合、捆绑、调整或改进,以满足SCD患者的特定需求。
