Usability evaluation of assistive technologies through qualitative research focusing on people with mild dementia

Discovering the barriers to scaling a co-design approach for the provision of custom assistive technology within healthcare services

Introduction: Using computer-aided design and 3D printing within a co-design process to produce assistive technology (AT) has a positive impact in delivering customised solutions to end-users' needs. However, to date its adoption within healthcare services has been limited. This work aims to gather clinicians' insights to identify and analyse barriers inherent in the AT design, manufacturing, and provision processes and inform a detailed understanding of the current AT eco-system. It forms part of a long-term ambition to efficiently scale up a service for the co-design of custom AT across specialties and healthcare services.

Methods: Five interactive workshops were run with 21 healthcare professionals currently involved in AT provision. Participants were recruited from two health boards in the UK. Thematic analysis was used to identify common barriers to scaling up a custom AT approach. Additionally, an eco-system map was created to determine the key stakeholders and their interactions.

Results: Nineteen descriptive themes, grouped into four analytical themes, were identified related to the design of AT, access to AT, healthcare staffing and healthcare system pressures. The eco-system map identified sixteen individual stakeholders and ten different groups of significant corporate stakeholders.

Discussion: The identified barriers relate to both the provision of off-the-shelf and the co-design of customised AT. Further promoting the scaling up of a co-design custom AT process requires: improving communication between stakeholders, enabling information about AT to be easily accessible, ensuring feedback is gathered and used, and creating tools that enable non-expert designers to modify custom AT designs safely and effectively.

A systematic review of reminder and guidance systems for Alzheimer's Disease and Related Dementias patients: context, barriers and facilitators

PURPOSE

To present the latest available research assessing the actual impact of reminder and guidance technologies for daily activities in Alzheimer's Disease and Related Dementia's patients, outlining design implications for these technologies.

MATERIALS AND METHODS

The search was conducted in the ACM Digital Library, IEEExplore, ScienceDirect, PubMed, Cochrane Library, Sage Journal, ResearchGate, and SemanticScholar. An iteratively-developed Boolean search string was built including up to 18 AND/OR terms across Four categories (Memory Aids, Technology, Daily Activities, Memory Impairment). We qualitatively analyzed the findings and discussions of the findings reported in 40 studies in our corpus to determine common barriers to, and facilitators of, effective intervention implementation and adoption.

RESULTS

Forty studies fulfilled the inclusion and exclusion criteria. In existing studies, individuals with Alzheimer's Disease and Related Dementias understand the usefulness of different functions that can be provided within an app to assist with everyday tasks. There was a high level of heterogeneity regarding the studies' location, duration, and evaluation methodology.

CONCLUSIONS

There is a need for assistive reminder and guidance technologies to be tailored towards autonomy, identity and personalization. Future work should include motivating features to aid during mood changes and feelings of insecurity.

Technology Usability for People Living With Dementia: Concept Analysis

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.

Outcomes of home design to support healthy cognitive ageing: modified e-Delphi exercise with older people and housing-related professionals

BACKGROUND

There is emerging agreement that living in a home designed to support healthy cognitive ageing can enable people to live better with dementia and cognitive change. However, existing literature has used a variety of outcome measures that have infrequently been informed by the perspectives of older people or of professional in design and supply of housing. The DesHCA (Designing Homes for Healthy Cognitive Ageing) study aimed to identify outcomes that were meaningful for these groups and to understand their content and meanings.

METHODS

A presurvey of older people and housing professionals (n = 62) identified potential outcomes. These were then used in three rounds of a modified e-Delphi exercise with a panel of older people and housing professionals (n = 74) to test meanings and identify areas of agreement and disagreement. Descriptive statistics were used to present findings from previous rounds.

RESULTS

The survey confirmed a wide range of possible outcomes considered important. Through the e-Delphi rounds, panellists prioritised outcomes relating to living at home that could be influenced by design, and clarified their understanding of the meanings of outcomes. In subsequent rounds, they commented on earlier results. The exercise enabled five key outcome areas to be identified - staying independent, feeling safe, living in an adaptable home, enabling physical activity and enabling enjoyed activities- which were then tested for their content and applicability in panellists' views.

CONCLUSION

The five key outcome areas appeared meaningful to panellists, whilst also demonstrating nuanced meanings. They indicate useful outcomes for future research, though will require careful definition in each case to become measures. Importantly, they are informed by the views of those most immediately affected by better or poorer home design.

Needs of older people living with dementia in low and middle-income Asian countries: A scoping review

BACKGROUND

Population ageing in low and middle-income Asian countries is associated with increased prevalence of dementia. The proportion of people with dementia in countries such as Bangladesh and Thailand are increasing. People with dementia can have complex care and health service needs. If these needs are not adequately met, this can result in a decreased quality of life and burden on the health system. There is considerable research into the needs of people with dementia in high-income countries. However, research on the needs of people living with dementia in low and middle-income countries remains underexplored. The aim of this study was to review and summarise the literature on the health and social care needs of older people with dementia in low and middle-income Asian countries.

METHODS

Five online databases (PubMed, Scopus, Web of Science, CINAHL and PsycINFO) and google scholar were searched. The databases were searched using a selection of key words. PRISMA-ScR approach was followed in reporting the process.

KEY FINDINGS

We extracted eight studies related to the health and social care needs of people with dementia that met our inclusion criteria. From the available literature, needs were categorised across five categories: (i) social, cognitive, and mental health needs; (ii) physical needs; (iii) care and service needs; (iv) knowledge-related needs; and (v) spiritual care needs.

CONCLUSION

While eight papers were located which discussed the needs of people with dementia across a range of domains, this review demonstrates a deficit in the current evidence-base about the health and social care needs of people living with dementia in low and middle-income Asian countries. Further research is needed to identify health and care needs of people with dementia and how these needs are being met.

Consumer direction in the field of digital technologies and people with dementia: a literature review

PURPOSE

Digital technologies have a great potential to improve the quality of life of people with dementia. However, this group is usually not involved in their development and dissemination. A consumer-directed role in the delivery of digital technologies could allow this group to regain autonomy and certain independence. This article aims to conceptualise the components of the Consumer Direction theory in the context of digital technologies and people with dementia.

METHOD

A literature review was conducted. We searched for studies within the aforementioned context in five relevant databases, covering the years 2012-2020. Identified studies were screened and assessed for inclusion. The data were categorised using two-stage qualitative content analysis.

RESULTS

Forty articles were included. The results provide definitions of the four components of the Consumer Direction theory in the context of this study. Namely, what it means for people with dementia to be (1) in control of technology use, (2) offered a variety of technological options, (3) informed and supported regarding the use and training of digital technologies, and (4) actively participating in systems design. These can lead to the empowerment of people with dementia.

CONCLUSION

The four theoretical components of the Consumer Direction theory are conceptualised differently in the context of this study. By providing new definitions, this paper contributes to research and practice. We expect the definitions to be deployed by researchers, practitioners, and policymakers for the creation of a more consumer-directed delivery of digital technologies to people with dementia.Implications for rehabilitationDigital technologies have a great potential to improve the quality of life of people with dementia.A consumer-directed role in the delivery of digital technologies could empower people with dementia and give them the opportunity to take control over the offered services as well as maintain a degree of independence.The Consumer Direction theory and its components should be conceptualised differently in the context of digital technologies and people with dementia than in previous contexts that used the theory.The new definitions can be utilised by researchers, practitioners and policymakers for the creation of a more consumer-directed delivery of digital technologies to people with dementia.

Feasibility and Acceptability of a Multidisciplinary Academic Telemedicine System for Memory Care in Response to COVID-19

Background and Objectives

In response to the restrictions imposed by the COVID-19 pandemic, the University of California San Francisco Memory and Aging Center (UCSF MAC) has deployed a comprehensive telemedicine model for the diagnosis and management of Alzheimer disease and related dementias. This review summarizes a large academic behavioral neurology clinic's experience transitioning to telemedicine services, including the impact on clinic care indicators, access metrics, and provider's experience. We compared these outcomes from 3 years before COVID-19 to 12 months after the transition to video teleconferencing (VTC) encounters.

Methods

Patient demographics and appointment data (dates, visit types, and departments) were extracted from our institution's electronic health record database from January 1, 2017, to May 1, 2021. We present data as descriptive statistics and comparisons using Wilcoxon rank-sum tests and Fisher exact tests. The results of anonymous surveys conducted among the clinic's providers are reported as descriptive findings.

Results

After the implementation of telemedicine services, the proportion of clinic encounters completed via VTC increased from 1.9% to 86.4%. There was a statistically significant decline in both the percentage of scheduled appointments that were canceled (32.9% vs 27.9%; p < 0.01) and total cancelations per month (mean 240.3 vs 179.4/mo; p < 0.01). There was an increase in the percentage of completed scheduled appointments (60.2% vs 64.8%; p < 0.01) and an increase in the average estimated commuting distance patients would need to drive for follow-up appointments (mean 49.8 vs 54.7 miles; p < 0.01). The transition to telemedicine services did not significantly affect the clinic's patient population as measured by age, gender, estimated income, area deprivation index, or self-reported racial/ethnic identity. The results of the provider survey revealed that physicians reported a more positive experience relative to neuropsychologists. Both types of providers reported telemedicine services as a reasonable equivalent and acceptable alternative to in-person evaluations with notable caveats.

Discussion

UCSF MAC's comprehensive integration of telemedicine services maintained critical ambulatory care to patients living with dementia during the COVID-19 pandemic. The recognized benefits of our care model suggest dementia telemedicine may be used as a feasible and equivalent alternative to in-person ambulatory care in the after COVID-19 era.

Exploring the barriers to using assistive technology for individuals with chronic conditions: a meta-synthesis review

PURPOSE

Assistive technology can provide a key tool to enabling independence, greater inclusion and participation in society for individuals with chronic conditions. This potential is currently not always realized due to barriers to accessing and using assistive technology. This review aims to identify the common barriers to acquiring and using assistive technology for users with chronic conditions through a systematic meta-synthesis. This differs from other systematic reviews by applying a transdiagnostic approach to identify if barriers are common across chronic conditions.

MATERIALS AND METHODS

A systematic literature search of five scientific databases (PubMed, SCOPUS, PsycINFO, CINAHL and Medline) was conducted to identify relevant qualitative studies. The search was conducted in November 2019. For the identified articles, thematic content analysis was conducted and the methodological quality was evaluated using the Critical Appraisal Skills Programme (CASP) checklist for qualitative research.

RESULTS

Forty papers met the inclusion criteria and were included in the analysis. Fifty-one descriptive themes grouped into six overarching analytical themes were identified from the studies. The analytical themes identified were: the design and function of the assistive technology, service provision, information and awareness, psychological barriers, support network and societal barriers.

CONCLUSIONS

The barriers are interconnected and common across different health conditions. More involvement in personalized care for developing strategies, adaptation of home technologies and provision of assistive technology could overcome the service provision and design barriers to assistive technology. Accessible information and providing greater awareness will be important to overcoming information, psychological and societal barriers to assistive technology.Implications for rehabilitationIndividuals with chronic conditions face complex barriers to acquiring and using assistive technology as a result of the devices themselves, their individual context, the healthcare context where assistive technology is provided and wider societal barriers.The provision of assistive technology needs to change away from the traditional medical model of the "expert" clinician and instead focus on more user involvement to deliver personalised care that utilises the users lived knowledge and experiences.Assistive technology provision should be considered alongside how to adapt everyday mainstream technology to meet user needs; the provision of devices should encourage creative problem solving rather then relying on pre-defined prescription lists of assistive technology.

Beyond instrumental support: Mobile application use by family caregivers of persons living with dementia

In recent years, there has been a rapid increase in technology use in dementia caregiving, particularly the use of mobile applications (apps) which are highly accessible, cost-effective and intuitive. Yet, little is known about the experiences of family caregivers of persons living with dementia who use apps to support caregiving activities. This is of particular concern given that limited understandings of the user experience in designing technology have often led to end-users experiencing barriers in technology adoption and use. Using a qualitative descriptive approach, the purpose of the study was to explore the experiences of family caregivers of persons living with dementia on using apps in their caregiving roles. A purposive sample of five family caregivers in Ontario, Canada participated in two interviews each, with the second interview informed by photo-elicitation methods. Thematic analysis of the collected data revealed a central overarching theme, Connecting to support through apps in my, your and our lives, which explicated how apps played an important role in the lives of the caregiver, the care recipient and both together as a dyad. Three core themes also emerged: Adapting apps to meet individual needs of the dyad, Minimising the impact of the condition on the person and the family and Determining the effectiveness of apps. The findings highlighted that the value of apps extends beyond their mere functionality and their ability to help with care provision as they are also able to promote richer interpersonal connections, enhance personhood and sustain family routines. This research advances our understanding of the impact of app use in caregiving and provides direction for future research, policy, education, practice and app development.

User experience and acceptance of a device assisting persons with dementia in daily life: a multicenter field study

Background

Assistive technologies have the potential to facilitate everyday life of people with dementia and their families. Close collaboration with affected people and interdisciplinary research are essential to understand and address the needs of prospective users. In this study, we present the results of the evaluation of such an assistive system prototype.

Aims

Challenges from the patient and caregiver side, technical and design problems and acceptance and usability with regard to our special target group were evaluated.

Methods

MEMENTO, a system of two e-ink tablets and a smartwatch, was tested in the domestic environment of dementia patients. Thirty participants from Italy, Spain and Austria took part in a 3-month field trial and compared the MEMENTO system to traditional strategies in everyday life. Quantitative and qualitative data were collected and frequency of use of the system was monitored.

Results

There were no significant changes in quantitative measurements, such as activities of daily living and caregiver burden over the duration of the 3-month field trial. More frequent usage was significantly correlated with positive attitude towards technology (r = 0.723, p < 0.05), but not with age. The design of the system was positively emphasized, reducing fear of the technology on the one hand and stigmatization on the other.

Conclusion

We show that a positive attitude towards technology is the essential variable for successful implementation of such systems, regardless of age. Participants showed great interest in digital solutions and agreed that technological systems will help in maintaining independency of persons with cognitive dysfunction in the future.

An Individual Cognitive Stimulation Therapy App for People with Dementia and Carers: Results from a Feasibility Randomized Controlled Trial (RCT)

BACKGROUND

There is a lack of digital resources that support the cognition and quality of life (QoL) of people with dementia. The individual cognitive stimulation therapy application (iCST app) aims to provide cognitive stimulation and social interaction to people with dementia and carers through interactive touch-screen technology. This study set out to determine the feasibility of conducting a full-scale, randomized controlled trial (RCT) with the iCST app.

METHODS

This was a single blind, feasibility RCT including people with mild to moderate dementia and their carers. Multiple trial components were assessed including recruitment and retention rates, intervention fidelity and usability, and acceptability of the outcome assessments which included measures of cognition and QoL. A sample of the intervention group was invited to a semi-structured post-trial interview to examine the experience of using the iCST app.

RESULTS

Sixty-one dyads were randomised to the iCST app (n = 31) or treatment-as-usual (TAU) control group (n = 30) for 11 weeks. In the iCST app group, 77% used the intervention for 20 minutes or more each week. Carers using the iCST app rated their QoL better at follow-up 2 compared to the TAU control group (EQ-5D, MD = 7.69, 95% CI = 2.32-13.06, p = 0.006). No significant differences were found on the other outcome measures.

CONCLUSION

The iCST app was deemed usable and enjoyable. Most participants completed the activities more quickly than anticipated and did not have enough activities to continue using the app frequently. Expansion of the iCST app is needed to maintain engagement for longer. Findings indicate that computerised cognitive stimulation can be beneficial, and a large-scale RCT is feasible with modifications to trial components. The results are relevant to researchers, software developers, policy-makers, people with dementia and carers who are looking to be involved in such interventions.

The patients' and caregivers' perspective: In-hospital navigation aids for people with dementia- a qualitative study with a value sensitive design approach

People with dementia (PwD) have serious difficulties orienting themselves in a hospital environment. In this qualitative study, we asked PwD and their informal caregivers about requirements for assistive technology when navigating in inpatient care settings. We aimed to provide user-centred recommendations for the development of an in-hospital navigation aid following a value sensitive design approach. We conducted semi-structured interviews with two stakeholder groups as potential future users of in-hospital navigation aids: PwD (n = 10, agemean = 83.9 years, MMSEmean = 21.2) and informal caregivers (n = 10, agemean = 75.9 years). The interviews were evaluated using qualitative content analysis in a multistage process involving six members of a self-help group for relatives of PwD as co-researchers. Independence and relief/respite were the most important values regarding assistive technology for PwD. Informal caregivers attributed greatest importance to safety and relief/respite. The underlying values of these stakeholder groups contribute to recommendations for designing new assistive technologies for patient-centred in-patient care: Assistive technology needs to overcome age- and disease-related limitations, and the resulting individual risks, while providing subsidiary assistance to maintain the desired independence of PwD for as long as possible.

Digital Health and Care Study on Elderly Monitoring

Sustainable technologies are being increasingly used in various areas of human life. While they have a multitude of benefits, they are especially useful in health monitoring, especially for certain groups of people, such as the elderly. However, there are still several issues that need to be addressed before its use becomes widespread. This work aims to clarify the aspects that are of great importance for increasing the acceptance of the use of this type of technology in the elderly. In addition, we aim to clarify whether the technologies that are already available are able to ensure acceptable accuracy and whether they could replace some of the manual approaches that are currently being used. A two-week study with people 65 years of age and over was conducted to address the questions posed here, and the results were evaluated. It was demonstrated that simplicity of use and automatic functioning play a crucial role. It was also concluded that technology cannot yet completely replace traditional methods such as questionnaires in some areas. Although the technologies that were tested were classified as being “easy to use”, the elderly population in the current study indicated that they were not sure that they would use these technologies regularly in the long term because the added value is not always clear, among other issues. Therefore, awareness-raising must take place in parallel with the development of technologies and services.

Dementia Care, Fall Detection, and Ambient-Assisted Living Technologies Help Older Adults Age in Place: A Scoping Review

OBJECTIVES

We aimed to describe recent technologic advances in the three domains of dementia care, falls, and home supports; summarize existing literature on usability; and identify knowledge gaps.

METHODS

A comprehensive search of five databases for recent peer-reviewed publications was conducted in May 2020. Independent reviewers performed title/abstract review, full-text screening, data extraction, and study characteristic summarization.

RESULTS

Out of 2,696 citations, 151 articles were retrieved for full-text evaluation, after which 54 studies were included in this scoping review. For each domain, different technologies are available to enhance the health and well-being of older adults; many users deemed them usable and useful. Technologies targeted improving function, psychosocial and cognitive status, home safety, and caregiver burden. Barriers to widespread uptake include privacy concerns, suboptimal user experience, and willingness to accept assistance.

CONCLUSION

Technologic innovations directed toward dementia care, fall detection, and ambient-assisted living can aid older adults "aging in place."

State-of-the-Art Sensors for Remote Care of People with Dementia during a Pandemic: A Systematic Review

In the last decade, there has been a significant increase in the number of people diagnosed with dementia. With diminishing public health and social care resources, there is substantial need for assistive technology-based devices that support independent living. However, existing devices may not fully meet these needs due to fears and uncertainties about their use, educational support, and finances. Further challenges have been created by COVID-19 and the need for improved safety and security. We have performed a systematic review by exploring several databases describing assistive technologies for dementia and identifying relevant publications for this review. We found there is significant need for appropriate user testing of such devices and have highlighted certifying bodies for this purpose. Given the safety measures imposed by the COVID-19 pandemic, this review identifies the benefits and challenges of existing assistive technologies for people living with dementia and their caregivers. It also provides suggestions for future research in these areas.

Improving the depth of data quality or increasing confusion? Reflections on a data analysis involving members of a self-help group for relatives of people living with dementia

Background

Public involvement in research to improve data quality and to empower different stakeholders is good scientific practice, but rarely implemented across all research phases.

Objective

This article reports on an attempt to involve members of a self‐help group for relatives of people living with dementia as co‐researchers in the data analysis in a short‐term format.

Methods

One researcher identified statements about assistive technologies from 17 interviews with people living with dementia and informal caregivers. Two researchers and six co‐researchers independently assigned pre‐defined values to these statements. Subsequently, we compared the values of the researchers and co‐researchers.

Results

The members of the self‐help group identified four original values not considered by the researchers: consent, inclusion, participation and respect.

Discussion

The involvement of co‐researchers led to an improvement in the depth of data quality through the joint identification of values concerning assistive technology. Language barriers between researchers, co‐researchers and interview participants impeded the data analysis.

Conclusion

The challenges and benefits of a participatory data analysis shown here can provide a basis for recommendations for target group‐specific research involvement. Our recommendations relate to the recruitment of co‐researchers, requirements for conducting a participatory data analysis and the participation degree of people involved.

Patient or Public Contribution

The group of co‐researchers participating in the data analysis consisted of relatives of people living with dementia.

The Impact of a Global Pandemic on People Living with Dementia and Their Care Partners: Analysis of 417 Lived Experience Reports

Background:

The COVID-19 pandemic is impacting the physical and emotional health of older adults living with dementia and their care partners.

Objective:

Using a patient-centered approach, we explored the experiences and needs of people living with dementia and their care partners during the COVID-19 pandemic as part of an ongoing evaluation of dementia support services in British Columbia, Canada.

Methods:

A survey instrument was developed around the priorities identified in the context of the COVID-19 and Dementia Task Force convened by the Alzheimer Society of Canada.

Results:

A total of 417 surveys were analyzed. Overall, respondents were able to access information that was helpful for maintaining their own health and managing a period of social distancing. Care partners reported a number of serious concerns, including the inability to visit the person that they care for in long-term or palliative care. Participants also reported that the pandemic increased their levels of stress overall and that they felt lonelier and more isolated than they did before the pandemic. The use of technology was reported as a way to connect socially with their loved ones, with the majority of participants connecting with others at least twice per week.

Conclusion:

Looking at the complex effects of a global pandemic through the experiences of people living with dementia and their care partners is vital to inform healthcare priorities to restore their quality of life and health and better prepare for the future.

A New Method for Structured Integration of User Needs in Two Health Technology Development Projects: Action Sheets

An early integration of users and stakeholders is needed for a successful innovation process. Nonetheless, the integration of users is often hard to realize - especially when dealing with persons with chronic diseases. In addition, patients or users in general often are not able to formulate the requirements in a technical manner. Therefore, even if user requirements are collected, it is not certain that the developers know or understand 'what is really wanted'. To overcome these 'gaps', we have developed so-called Action Sheets (AS). This article presents the use of AS in two projects: the development of health technologies for people with cancer (INFOPAT) and dementia (QuartrBack). Depending on the project context, group sessions were conducted with different stakeholders to identify the needs of (potential) users. Within the INFOPAT project, ten focus groups were conducted with patients, physicians and other healthcare professionals. In QuartrBack stakeholders like e.g. care professionals, technical assistance organizations and citizens participated in two focus groups and three world cafés. Their requirements were then 'fed' into the technology development by the use of AS. AS appear to be a promising tool to make user needs based on social values more tangible and implementable into technology development processes. In addition, it shows up that four phases seem to be necessary for transferring identified user and stakeholder needs into AS, which can therefore be seen as essential to translate non-technically formulated requirements into technically feasible ones. The case study shows as lessons learned that despite the successful integration of user needs, context-sensitive adjustments are still necessary.

Why do older people love and hate assistive technology? ‒ an emotional experience perspective

Assistive technology is increasingly valued to support older people with functional decline and disabilities. Inspired by classical theories on technology acceptance, emotional experience, and psychological needs, this study aimed to better understand the use of assistive technology by older people. Qualitative semi-structured interviews were conducted with 50 community-dwelling older adults in Hong Kong (mean age = 67.47, standard deviation = 7.96). Thematic analysis was used to generate themes. Positive and negative emotional experiences emerged as two themes. The theme of positive emotional experiences is associated with enhanced security, independence, and relativeness. However, assistive technology may also produce anxiety, frustration, stigma, isolation, and risks that induce negative emotional experiences. These findings indicate that older users' emotional and psychological concerns should be addressed and reflected in the process of assistive technology product design and implementation. Practitioner summary: To enhance the well-being of older people through the application of assistive technology, it is necessary to maximise autonomy or independence, enhance social relativeness, and lift self-competence to evoke positive emotional experiences.

Evaluating the Facilitators, Barriers, and Medical Outcomes Commensurate with the Use of Assistive Technology to Support People with Dementia: A Systematic Review Literature

Background: Assistive technologies (AT) have been used to improve the daily living conditions of people living with dementia (PWD). Research supports the positive impact of the use of AT such as decreased burden on caregivers and behavioral support for people with dementia. Four reviews in the last six years have analyzed AT and PWD, but none have incorporated the dimension of medical outcomes. Objectives: The purpose of this review is to identify the facilitators, barriers, and medical outcomes commensurate with the use of AT with PWD. Method: This review queried The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Web of Science, Science Direct, and PubMed databases for peer-reviewed publications in the last five years for facilitators, barriers, and medical outcomes commensurate with the use of AT with PWD. The study is reported and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and the Kruse Protocol for conducting a systematic review. Results: 48 studies were analyzed. Fourteen types of AT, 17 facilitators, 17 barriers, and 16 medical outcomes were identified in the literature. The two most frequently mentioned ATs were cognitive stimulators (9/48, 19%) and social robots (5/48, 10%). The two most frequently mentioned facilitators were caregivers want AT (8/68, 12%) and enables increased independence (7/68, 10%). The top two barriers were cost (8/75, 11%) and PWD reject AT (8/75, 11%). The top medical outcomes were improved cognitive abilities (6/69, 9%), increased activities of daily living (ADLs), and increased autonomy (each at 5/69, 7%): Zero negative outcomes were reported. Conclusion: The systematic review revealed the positive relations that occur when PWD and their caregivers use AT. Although many reservations surrounding the use of AT exist, a majority of the literature shows a positive effect of its use. Research supports a strong support for AT by caregivers due to many positive medical outcomes, but also a reticence to adopt by PWD. If ATs for PWD are a way to reduce stress on caregivers, barriers of cost and complexity need to be addressed through health policy or grants.

Using sensor-based technology for safety and independence - the experiences of people with dementia and their families

BACKGROUND

The majority of people with dementia prefer to live independently and safely in their own home cared for by their family members. Much effort has been invested in the development of technology, such as sensor-based networks. Many challenges remain, in particular gaining more knowledge about their experiences and perceived benefits. This study aimed to explore experiences, needs and benefits with using sensor-based technology for safety and independence in the homes of people with dementia and their family members.

METHODS

This study is part of the TECH@HOME project, aiming to evaluate the effects of sensor-based technology on independence among people with dementia and caregiver stress among their family members. This study applied an inductive, qualitative approach with semi-structured interviews of people with dementia (n = 9) and family members (n = 21). The participants were interviewed between June and September 2018 after using the technology for at least 6 months. The interviews were analysed with manifest content analysis.

RESULTS

Our findings highlighted that technology was considered as a precaution and a safety measure that could provide a sense of having control of the everyday life of the person with dementia. Understanding and acceptance of the technology were as important, together with the reliability of the technology. Ethical dilemmas related to the monitoring of the person with dementia in the home were also raised.

CONCLUSION

This study provides insights into how people with dementia and family members experience and benefit from using sensor-based technology in their own homes. The knowledge generated is essential for healthcare professionals and policymakers developing and implementing care and service systems including technology, as well as for the industry.

Needs of people with dementia and their informal caregivers concerning assistive technologies

Background and objective: Assistive technologies might be a suitable option for supporting people with dementia and their informal caregivers. To avoid "one-fits-all"-solutions and to design useful technologies, it is essential to consider the end-users' needs. The objective of this review was to examine the needs of people with dementia and their informal caregivers with regard to assistive technologies. Methods: We conducted a scoping review based on a comprehensive literature search in databases, handsearching, and free web searching. Additionally, we performed citation tracking of included studies. We included all types of study designs. Two researchers independently selected the studies. The results were thematically categorised by two researchers. Results: The search yielded 7160 references. 18 of 24 included studies were qualitative. The studies had been conducted in 13 different countries, mostly in Europe. The sample size ranged between two and 270 participants. Most of the studies involved people with dementia as well as informal caregivers. The analysis resulted in eleven themes. The themes could be assigned to three domains: "needed technologies", "characteristics of needed technologies", and "information about technologies". Conclusions: The results might guide future usage, development and research addressing end users' needs with regard to assistive technologies.

Understanding the assistive technology needs of people over 55: The future of mobility aids

OBJECTIVE

To understand mobility issues not adequately serviced by assistive technology (AT).

METHODS

A two-stage mixed-methods research project that forms the basis of future AT design and manufacture. Stage 1: a focus group comprising 46 participants (people aged 55 years or older with mobility issue/s) and their support networks. Stage 2: a sample of 413 people over 55 completed a purpose-designed survey informed by stage 1, regarding mobility issues and perceived desirability of suggested AT mobility aids.

RESULTS

Two core themes emerged: (a) functionality issues relating to existing AT designs and (b) identified mobility issues encountered during activities of daily living that could potentially be resolved by developing new AT. Importance was placed on certain features of AT mobility aids with cost, transportability and aesthetics being primary issues.

CONCLUSION

Consulting end-users and their networks ensures valuable insight into how future AT can better address and target mobility needs.

The Multidisciplinary Approach to Alzheimer's Disease and Dementia. A Narrative Review of Non-Pharmacological Treatment

Background: Alzheimer's disease (AD) and dementia are chronic diseases with progressive deterioration of cognition, function, and behavior leading to severe disability and death. The prevalence of AD and dementia is constantly increasing because of the progressive aging of the population. These conditions represent a considerable challenge to patients, their family and caregivers, and the health system, because of the considerable need for resources allocation. There is no disease modifying intervention for AD and dementia, and the symptomatic pharmacological treatments has limited efficacy and considerable side effects. Non-pharmacological treatment (NPT), which includes a wide range of approaches and techniques, may play a role in the treatment of AD and dementia. Aim: To review, with a narrative approach, current evidence on main NPTs for AD and dementia. Methods: PubMed and the Cochrane database of systematic reviews were searched for studies written in English and published from 2000 to 2018. The bibliography of the main articles was checked to detect other relevant papers. Results: The role of NPT has been largely explored in AD and dementia. The main NPT types, which were reviewed here, include exercise and motor rehabilitation, cognitive rehabilitation, NPT for behavioral and psychological symptoms of dementia, occupational therapy, psychological therapy, complementary and alternative medicine, and new technologies, including information and communication technologies, assistive technology and domotics, virtual reality, gaming, and telemedicine. We also summarized the role of NPT to address caregivers' burden. Conclusions: Although NPT is often applied in the multidisciplinary approach to AD and dementia, supporting evidence for their use is still preliminary. Some studies showed statistically significant effect of NPT on some outcomes, but their clinical significance is uncertain. Well-designed randomized controlled trials with innovative designs are needed to explore the efficacy of NPT in AD and dementia. Further studies are required to offer robust neurobiological grounds for the effect of NPT, and to examine its cost-efficacy profile in patients with dementia.

User experience and clinical effectiveness with two wearable global positioning system devices in home dementia care

INTRODUCTION

The user experience and clinical effectiveness with wearable global positioning system (GPS) devices for persons with dementia (PwDs) and caregivers (CGs) remain unclear although many are available.

METHODS

Using a crossover design, 20 dyads tested two similar commercial GPS watches (products A and B) at home for 4 weeks each. Usability, product functions, design features and product satisfaction at home and the clinic were investigated. Caregiver burden and quality of life assessed clinical effectiveness.

RESULTS

The final 17 dyads rated the usability, telephone function, overall design features, font, buttons, and battery life of B significantly better than A. PwDs rated the overall design features and buttons of A significantly better than CGs. Product satisfaction with both products was significantly lower at home. Clinical effectiveness was not found.

DISCUSSION

User experience can be improved by optimizing specific product details. This might translate to clinical effectiveness. Social desirability bias may explain different product satisfaction ratings.

Recognition of preclinical signs of dementia: A qualitative study exploring the experiences of family carers and professional care assistants

AIMS AND OBJECTIVES

To identify preclinical signs of dementia by exploring the experiences of family caregivers and professional care assistants.

BACKGROUND

Dementia results in disability, emotional strain and financial loss for people with dementia, family members and nations. Informal identification of social and behavioural risk signifiers could facilitate timely interventions with potential to delay onset of serious disability.

DESIGN

A retrospective qualitative approach using a naturalistic interpretive design was used. Focus groups enabled in-depth understanding of the participants' experiences of life or work with people who subsequently developed dementia.

METHODS

Purposive sampling was used to recruit family carers and professional carers who had cared for people who later developed dementia. The data from focus groups were fully transcribed and anonymised, and transcripts were analysed by two researchers. These researchers coded and analysed the transcripts independently; subsequently, overlapping and similar themes were identified and consensus reached on final themes. A third researcher was invited to review the analysis and ensure trustworthiness of the study findings.

RESULTS

Findings revealed that preclinical signs of dementia were identifiable in retrospect Participants' accounts resulted in four themes, "Lowered Threshold of Frustration", "Insight and Coping Strategies," "Early signs of poor memory" and "Alarming Events."

CONCLUSIONS

Earlier recognition of preclinical signs of dementia would allow affected individuals to follow health promotion advice and plan for the future. Identification of social exclusion prior to diagnosis has implications for antistigma campaigns and development of "dementia-friendly communities."

RELEVANCE TO CLINICAL PRACTICE

Healthcare professionals could work with those at risk, facilitating lifestyle changes to postpone symptoms and advance planning for improved autonomy. Predementia should be viewed as a disability for which reasonable adjustments can be made at a community level, to enhance and extend emotional well-being and social inclusion.
