背景:可用性是技术产品质量的关键指标。随着技术的进步,痴呆症患者的潜在使用正在增加。然而,为痴呆症患者定义技术的可用性仍然是一个持续的挑战。痴呆症的多样性和渐进性增加了创建通用可用性标准的复杂性,强调需要有重点的审议。技术干预为痴呆症患者和护理人员提供了潜在的好处。在COVID-19中,技术在医疗保健领域的作用越来越大,尤其是老年人。要使不同的痴呆症患者能够享受技术带来的好处,需要特别关注他们的需求,欲望,能力,以及技术对潜在危害的脆弱性。成功的痴呆症技术干预需要仔细考虑技术可用性。
目的:本概念分析旨在研究技术在痴呆症患者的背景下的可用性,以在该特定人口统计学中建立明确的可用性定义。
方法:使用Walker和Avant的框架来指导此概念分析。我们进行了1984年至2024年的文献综述,通过PubMed探索痴呆症患者的技术可用性,WebofScience,和谷歌学者数据库使用关键字“技术可用性”和“痴呆症”。“我们还纳入了来自29个二元组的临床定义和综合访谈数据,这些二元组包括轻度阿尔茨海默痴呆症患者及其各自的护理伙伴。共有58名老年人。这种方法旨在更全面地描述痴呆症患者的可用性需求,强调实际应用。
结果:来自文献综述的证据揭示了可用性包括诸如可接受的可学习性等属性,效率,和满意度。痴呆症分期的临床观点,亚型,和症状强调了定制技术可用性评估的重要性。来自29个二元组的反馈也强调了简单性的价值,清除导航,对年龄敏感的设计,个性化的特点,和音频支持。因此,设计应该优先考虑为痴呆症患者提供个性化帮助,远离标准化的技术方法。从各种来源合成,为痴呆症患者定义的可用性属性不仅包括有效性的一般可用性属性,效率,和满意度,但也包括其他关键因素:适应性,个性化,直觉,和简单,以确保技术是支持性的,并为这一人群带来切实的利益。
结论:在设计技术干预措施时,可用性对于痴呆症患者至关重要。它需要了解用户特征,痴呆症阶段,症状,需要,和任务,以及对不同身体要求的考虑,潜在的感官损失,和年龄相关的变化。疾病进展需要适应不断发展的症状。建议包括多才多艺,多功能技术设计;适应不同的需求;并调整软件功能以实现个性化。产品特征分类可以灵活地基于用户条件。
BACKGROUND: Usability is a key indicator of the quality of technology products. In tandem with technological advancements, potential use by individuals with dementia is increasing. However, defining the usability of technology for individuals with dementia remains an ongoing challenge. The diverse and progressive nature of dementia adds complexity to the creation of universal usability criteria, highlighting the need for focused deliberations. Technological interventions offer potential benefits for people living with dementia and caregivers. Amid COVID-19, technology\'s role in health care access is growing, especially among older adults. Enabling the diverse population of people living with dementia to enjoy the benefits of technologies requires particular attention to their needs, desires, capabilities, and vulnerabilities to potential harm from technologies. Successful technological interventions for dementia require meticulous consideration of technology usability.
OBJECTIVE: This concept analysis aims to examine the usability of technology in the context of individuals living with dementia to establish a clear definition for usability within this specific demographic.
METHODS: The framework by Walker and Avant was used to guide this concept analysis. We conducted a literature review spanning 1984 to 2024, exploring technology usability for people with dementia through the PubMed, Web of Science, and Google Scholar databases using the keywords \"technology usability\" and \"dementia.\" We also incorporated clinical definitions and integrated interview data from 29 dyads comprising individuals with mild Alzheimer dementia and their respective care partners, resulting in a total of 58 older adults. This approach aimed to offer a more comprehensive portrayal of the usability needs of individuals living with dementia, emphasizing practical application.
RESULTS: The evidence from the literature review unveiled that usability encompasses attributes such as acceptable learnability, efficiency, and satisfaction. The clinical perspective on dementia stages, subtypes, and symptoms underscores the importance of tailored technology usability assessment. Feedback from 29 dyads also emphasized the value of simplicity, clear navigation, age-sensitive design, personalized features, and audio support. Thus, design should prioritize personalized assistance for individuals living with dementia, moving away from standardized technological approaches. Synthesized from various sources, the defined usability attributes for individuals living with dementia not only encompass the general usability properties of effectiveness, efficiency, and satisfaction but also include other key factors: adaptability, personalization, intuitiveness, and simplicity, to ensure that technology is supportive and yields tangible benefits for this demographic.
CONCLUSIONS: Usability is crucial for people living with dementia when designing technological interventions. It necessitates an understanding of user characteristics, dementia stages, symptoms, needs, and tasks, as well as consideration of varied physical requirements, potential sensory loss, and age-related changes. Disease progression requires adapting to evolving symptoms. Recommendations include versatile, multifunctional technology designs; accommodating diverse needs; and adjusting software functionalities for personalization. Product feature classification can be flexible based on user conditions.
