Overcoming barriers to the adoption of locating technologies in dementia care: a multi-stakeholder focus group study.

BACKGROUND: Locating technologies are a subtype of assistive technology that aim to support persons with dementia by helping manage spatial orientation impairments and provide aid to care partners by intervening when necessary. Although a variety of locating devices are commercially available, their adoption has remained low in the past years. Several studies have explored barriers to the adoption of assistive technologies from the perspective of professional stakeholders, but in-depth explorations for locating technologies are sparse. Additionally, the inputs of business professionals are lacking. The aim of this study was to expand knowledge on barriers to the adoption of locating technologies from a multi-stakeholder professional perspective, and to explore strategies to optimize adoption. METHODS: In total, 22 professionals working in business (n = 7), healthcare (n = 6) and research (n = 9) fields related to gerontology and gerontechnology participated in our focus group study. Perceptions on the value of using locating technologies for dementia care, barriers to their adoption, as well as salient services and information dissemination strategies were explored. After verbatim transcription, transcripts were analysed following an inductive data-driven content analysis approach in MAXQDA. RESULTS: Six key adoption barriers centering on: (1) awareness-, (2) technological-, (3) product characteristic- and (4) capital investment-based limitations, (5) unclear benefits, as well as (6) ethical concerns emerged. The interplay between barriers was high. Five core themes on services and information dissemination strategies centering on: (1) digital autonomy support, (2) emergency support, (3) information dissemination actors, (4) product acquisition, and (5) product advertising were extracted. CONCLUSIONS: Our study with interdisciplinary stakeholders expands knowledge on barriers to the adoption of locating technologies for dementia care, and reinforces recommendations that an interdisciplinary strategy is needed to optimize adoption. Also, our findings show that focusing on services to increase digital autonomy and on information dissemination strategies has been largely overlooked and may be particularly effective.

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.

Technology for home dementia care: A prototype locating system put to the test.

INTRODUCTION: The user experience of persons with dementia and their primary caregivers with locating systems is not firmly established. METHODS: Eighteen dyads used a prototype locating system during 4 weeks. Primary outcome measures were ratings of usability, and product functions and features. Secondary outcome measures were caregiver burden, perceived self-efficacy, frequency of use, and willingness to purchase the prototype. Changes in scores between baseline (T1) and end of testing period (T2) were compared by performing independent and dependent samples correlations and descriptive statistics. RESULTS: Seventeen dyads made up the final sample. Ratings of usability and product functions and features were fair, but usability ratings were significantly reduced after 4 weeks. Although the prototype was used infrequently by majority of the participants, most caregivers would be willing to purchase the prototype, with men more willing than women. No significant change in technological willingness, caregiver burden, or perceived self-efficacy was found between T1 and T2. Perceived self-efficacy significantly negatively correlated with willingness to purchase the prototype after 4 weeks. DISCUSSION: Results highlight the importance of including end users in the research and development phase of locating systems to improve the user experience in home dementia care. Necessary indications for further research are carrying out randomized controlled trials with larger, more representative samples and developing innovative software and hardware solutions.

[Acceptance of dementia diagnostics by getriatric hospital patients : Comparison of various investigation methods with emphasis on FDG-PET imaging]. / Akzeptanz der Demenzdiagnostik bei stationären, geriatrischen Patienten : Vergleich verschiedener Untersuchungsmethoden mit Fokus auf der FDG-PET-Untersuchung.

BACKGROUND: The number of people with dementia is continuously rising, in hospitals as well. For the diagnostics novel methods are available but the attitude of the patients to these methods is yet unknown. OBJECTIVE: The aim of the study was to evaluatethe opinion of geriatric hospital patients with suspected dementia on the various possible methods of diagnosing dementia, especially fluorodeoxyglucose positron emission tomography (FDG-PET). Additionally, it was assessed if there are differences in toleration between imaging of the brain and conventional diagnostics by neuropsychological testing and if information on the diagnostic methods and the patient's physical or cognitive status influence their opinion. METHOD: Within the framework of the iDSS001 clinical trial 90 geriatric hospital patients with suspected dementia were interviewed with respect to examinations performed for diagnosing dementia, e.g. anamnesis including physical and neurological examinations, neuropsychological testing, cerebrospinal fluid analysis, magnetic resonance imaging (MRI) and FDG-PET imaging. RESULTS: Imaging of the brain was tolerated less than anamnesis including physical and neurological examinations, neuropsychological testing and cerebrospinal fluid analysis and patients also felt they were less informed about these procedures. The generally well-accepted FDG-PET imaging procedure was received slightly better than MRI. Cognitively impaired and less depressed patients were less willing to allow repeat MRI examinations. CONCLUSION: The results suggest that imaging of the brain is perceived by cognitively impaired hospital patients as being more burdensome than conventional diagnostics, such as neuropsychological testing. Improved care during the investigations as well as physical and organizational adjustments could increase the acceptance.
