Clinical trial of a home safety toolkit for Alzheimer's disease

A Feasibility Study of Individuals Living at Home with Alzheimer's Disease and Related Dementias: Utilization of Visual Mapping Assistive Technology to Enhance Quality of Life and Reduce Caregiver Burden

Efficacy of assistive technology continues to evolve as a means of helping individuals with cognitive and intellectual disabilities, asserting the importance of its research. We report outcomes of a six-week randomized control feasibility study in a small cohort of 16 family caregivers of individuals living with Alzheimer's disease and related dementias. An experimental group of seven family caregivers used visual mapping software on smart devices (step-by-step pictures, audio, and videos instructing how to complete a task) to support carrying out activities of daily living with their care recipients. In comparison, control group of nine family caregivers used smart devices to access and view educational videos focused on dementia care. After a six-week study, compared to caregivers using educational videos, caregivers using visual maps assistive technology reported higher satisfaction of use and stronger recommendation of use to others. Caregivers using visual maps technology also exhibited more improved quality of life scores and improved completion of activities of daily living for their dementia care recipients, as well as reduced caregiver burden scores compared to the caregivers in the control group. These promising findings show that the use of assistive technology is feasible in the home setting and suggest time is ripe for undertaking systematic studies of assistive technology's potential to advance effective behavioral interventions in dementia home and family settings.

Development of a behavioural framework for dementia care partners' fall risk management

BACKGROUND

Although older adults living with dementia (OLWD) are at high risk for falls, few strategies that effectively reduce falls among OLWD have been identified. Dementia care partners (hereinafter referred to as "care partners") may have a critical role in fall risk management (FRM). However, little is known about the ways care partners behave that may be relevant to FRM and how to effectively engage them in FRM.

METHODS

Semi-structured, in-depth interviews were conducted with 14 primary care partners (age: 48-87; 79% women; 50% spouses/partners; 64% completed college; 21% people of colour) of community-dwelling OLWD to examine their FRM behaviours, and their observations of behaviours adopted by other care partners who were secondary in the caring role.

RESULTS

The analysis of interview data suggested a novel behavioural framework that consisted of eight domains of FRM behaviours adopted across four stages. The domains of FRM behaviours were 1. functional mobility assistance, 2. assessing and addressing health conditions, 3. health promotion support, 4. safety supervision, 5. modification of the physical environment, 6. receiving, seeking, and coordinating care, 7. learning, and 8. self-adjustment. Four stages of FRM included 1. supporting before dementia onset, 2. preventing falls, 3. preparing to respond to falls, and 4. responding to falls. FRM behaviours varied by the care partners' caring responsibilities. Primary care partners engaged in behaviours from all eight behavioural domains; they often provided functional mobility assistance, safety supervision, and modification of the physical environment for managing fall risk. They also adopted behaviours of assessing and addressing health conditions, health promotion support, and receiving, seeking and coordinating care without realizing their relevance to FRM. Secondary care partners were reported to assist in health promotion support, safety supervision, modification of the physical environment, and receiving, seeking, and coordinating care.

CONCLUSIONS

The multi-domain and multi-stage framework derived from this study can inform the development of tools and interventions to effectively engage care partners in managing fall risk for community-dwelling OLWD.

Components, impacts and costs of dementia home support: a research programme including the DESCANT RCT

Background

Over half of people with dementia live at home. We know little about what home support could be clinically effective or cost-effective in enabling them to live well.

Objectives

We aimed to (1) review evidence for components of home support, identify their presence in the literature and in services in England, and develop an appropriate economic model; (2) develop and test a practical memory support package in early-stage dementia, test the clinical effectiveness and cost-effectiveness of routine home support in later-stage dementia and design a toolkit based on this evidence; and (3) elicit the preferences of staff, carers and people with dementia for home support inputs and packages, and evaluate the cost-effectiveness of these approaches in early- and later-stage dementia.

Design

We undertook (1) an evidence synthesis, national surveys on the NHS and social care and an economic review; (2) a multicentre pragmatic randomised trial [Dementia Early Stage Cognitive Aids New Trial (DESCANT)] to estimate the clinical effectiveness and cost-effectiveness of providing memory aids and guidance to people with early-stage dementia (the DESCANT intervention), alongside process evaluation and qualitative analysis, an observational study of existing care packages in later-stage dementia along with qualitative analysis, and toolkit development to summarise this evidence; and (3) consultation with experts, staff and carers to explore the balance between informal and paid home support using case vignettes, discrete choice experiments to explore the preferences of people with dementia and carers between home support packages in early- and later-stage dementia, and cost–utility analysis building on trial and observational study.

Setting

The national surveys described Community Mental Health Teams, memory clinics and social care services across England. Recruitment to the trial was through memory services in nine NHS trusts in England and one health board in Wales. Recruitment to the observational study was through social services in 17 local authorities in England. Recruitment for the vignette and preference studies was through memory services, community centres and carers’ organisations.

Participants

People aged > 50 years with dementia within 1 year of first attendance at a memory clinic were eligible for the trial. People aged > 60 years with later-stage dementia within 3 months of a review of care needs were eligible for the observational study. We recruited staff, carers and people with dementia for the vignette and preference studies. All participants had to give written informed consent.

Main outcome measures

The trial and observational study used the Bristol Activities of Daily Living Scale as the primary outcome and also measured quality of life, capability, cognition, general psychological health and carers’ sense of competence.

Methods

Owing to the heterogeneity of interventions, methods and outcome measures, our evidence and economic reviews both used narrative synthesis. The main source of economic studies was the NHS Economic Evaluation Database. We analysed the trial and observational study by linear mixed models. We analysed the trial by ‘treatment allocated’ and used propensity scores to minimise confounding in the observational study.

Results

Our reviews and surveys identified several home support approaches of potential benefit. In early-stage dementia, the DESCANT trial had 468 randomised participants (234 intervention participants and 234 control participants), with 347 participants analysed. We found no significant effect at the primary end point of 6 months of the DESCANT intervention on any of several participant outcome measures. The primary outcome was the Bristol Activities of Daily Living Scale, for which scores range from 0 to 60, with higher scores showing greater dependence. After adjustment for differences at baseline, the mean difference was 0.38, slightly but not significantly favouring the comparator group receiving treatment as usual. The 95% confidence interval ran from –0.89 to 1.65 (p = 0.56). There was no evidence that more intensive care packages in later-stage dementia were more effective than basic care. However, formal home care appeared to help keep people at home. Staff recommended informal care that cost 88% of formal care, but for informal carers this ratio was only 62%. People with dementia preferred social and recreational activities, and carers preferred respite care and regular home care. The DESCANT intervention is probably not cost-effective in early-stage dementia, and intensive care packages are probably not cost-effective in later-stage dementia. From the perspective of the third sector, intermediate intensity packages were cheaper but less effective. Certain elements may be driving these results, notably reduced use of carers’ groups.

Limitations

Our chosen outcome measures may not reflect subtle outcomes valued by people with dementia.

Conclusions

Several approaches preferred by people with dementia and their carers have potential. However, memory aids aiming to affect daily living activities in early-stage dementia or intensive packages compared with basic care in later-stage dementia were not clinically effective or cost-effective.

Future work

Further work needs to identify what people with dementia and their carers prefer and develop more sensitive outcome measures.

Caregiver Satisfaction with a Video Telehealth Home Safety Evaluation for Dementia

Family caregivers are vital to telehealth-delivered dementia care. The objective of this mixed methods descriptive study conducted in the VA Bedford Healthcare System was to examine caregiver satisfaction with a video telehealth dementia home safety occupational therapy evaluation. Ten caregivers of Veterans with dementia participated. Ratings of caregiver satisfaction, measured by nine Likert scale items including ability to see and hear, were examined in relation to person and visit-related contextual factors extracted from research assistants' field notes, to develop an in-depth understanding of caregiver experience. Person factors included caregiver age and gender and Veteran cognitive status. Visit-related contextual factors included occurrence of technical glitches. Caregiver visit satisfaction was overall positive, with exceptions related to technological glitches and the presence of the person with dementia during the visit. Veteran cognitive status appeared to influence caregiver satisfaction. Implications of the study are that proactively addressing technical glitches and incorporating dementia stage-specific approaches may optimize caregivers' telehealth experience.

Directed content analysis of Veterans Affairs policy documents: A strategy to guide implementation of a dementia home safety toolkit for Veterans to promote ageing in place

Older adults' preference to age in place, coupled with an increasing prevalence of dementia, creates an imperative to address home safety risks that occur due to cognitive impairment. Providing caregivers with home safety items and education can facilitate ageing in place for older adults living with dementia. In 2015-2017, we examined barriers and facilitators within 17 policy documents and dementia guidelines of the United States (US) Veterans Health Administration pertinent to implementation of a home safety toolkit (HST) for Veterans living with dementia. The documents were issued from 2000 to 2015. Directed qualitative content analysis of these documents guided by themes from stakeholder interviews revealed two key implementation barriers: a focus on physical rather than cognitive risks when determining medical necessity for home equipment, and a focus on rehabilitation and treatment rather than prevention. Mandates for person-centred care planning, including comprehensive assessment, interdisciplinary collaboration, staff education and a focus on population health in primary care facilitate HST implementation. Content analysis can identify policy-level barriers that slow innovation and facilitators that can increase access to care that support ageing in place.

Effectiveness of assistive technology in improving the safety of people with dementia: a systematic review and meta-analysis

Objectives: Assistive technology (AT) may enable people with dementia to live safely at home for longer, preventing care home admission. This systematic review assesses the effectiveness of AT in improving the safety of people with dementia living in the domestic setting, by searching for randomised controlled trials, non-randomised controlled trials and controlled before-after studies which compared safety AT with treatment as usual. Measures of safety include care home admission; risky behaviours, accidents and falls at home; and numbers of deaths. The review updates the safety aspect of Fleming and Sum's 2014 systematic review. Method: Seven bibliographic databases, the Social Care Institute for Excellence website and the Alzheimer's Society website were searched for published and unpublished literature between 2011-2016. Search terms related to AT, dementia and older people. Common outcomes were meta-analysed. Results: Three randomised controlled trials were identified, including 245 people with dementia. No significant differences were found between intervention and control groups in care home admission (risk ratio 0.85 95% CI [0.37, 1.97]; Z = 0.37; p = 0.71). The probability of a fall occurring was 50% lower in the intervention group (risk ratio 0.50 95% CI [0.32, 0.78]; Z = 3.03; p = 0.002). One included study found that a home safety package containing AT significantly reduced risky behaviour and accidents (F(45) = 4.504, p < 0.001). Limitations include the few studies found and the inclusion of studies in English only. Conclusion: AT's effectiveness in decreasing care home admission is inconclusive. However, the AT items and packages tested improved safety through reducing falls risk, accidents and other risky behaviour.

Feasibility of Telehealth-Delivered Home Safety Evaluations for Caregivers of Clients With Dementia

Video telehealth can increase access to home-based care, thus allowing older adults to maintain functional independence and age-in-place. This is particularly salient for persons with dementia whose cognitive changes increase home safety risk. Little is known about the technological and safety challenges of in-home assessment via video. This feasibility study explored the process and resource requirements of a remotely delivered telehealth occupational therapy home safety evaluation from a Veterans Health Administration (VHA) site. A total of 10 caregivers of veterans with dementia received home safety evaluations using videoconferencing technology using a variety of portable computing devices. Most telehealth evaluations experienced technological difficulties, but formal technical support was only required twice. Videoconferencing is a feasible service delivery option for home safety evaluations; however, infrastructure must support technological needs and client or provider gaps in knowledge. Implications for non-VHA settings and other interventions using videoconferencing are discussed.

Methodological review: quality of randomized controlled trials in health literacy

BACKGROUND

The growing move towards patient-centred care has led to substantial research into improving the health literacy skills of patients and members of the public. Hence, there is a pressing need to assess the methodology used in contemporary randomized controlled trials (RCTs) of interventions directed at health literacy, in particular the quality (risk of bias), and the types of outcomes reported.

METHODS

We conducted a systematic database search for RCTs involving interventions directed at health literacy in adults, published from 2009 to 2014. The Cochrane Risk of Bias tool was used to assess quality of RCT implementation. We also checked the sample size calculation for primary outcomes. Reported evidence of efficacy (statistical significance) was extracted for intervention outcomes in any of three domains of effect: knowledge, behaviour, health status. Demographics of intervention participants were also extracted, including socioeconomic status.

RESULTS

We found areas of methodological strength (good randomization and allocation concealment), but areas of weakness regarding blinding of participants, people delivering the intervention and outcomes assessors. Substantial attrition (losses by monitoring time point) was seen in a third of RCTs, potentially leading to insufficient power to obtain precise estimates of intervention effect on primary outcomes. Most RCTs showed that the health literacy interventions had some beneficial effect on knowledge outcomes, but this was typically for less than 3 months after intervention end. There were far fewer reports of significant improvements in substantive patient-oriented outcomes, such as beneficial effects on behavioural change or health (clinical) status. Most RCTs featured participants from vulnerable populations.

CONCLUSIONS

Our evaluation shows that health literacy trial design, conduct and reporting could be considerably improved, particularly by reducing attrition and obtaining longer follow-up. More meaningful RCTs would also result if health literacy trials were designed with public and patient involvement to focus on clinically important patient-oriented outcomes, rather than just knowledge, behaviour or skills in isolation.

2015 Alzheimer's disease facts and figures

This report discusses the public health impact of Alzheimer’s disease (AD), including incidence and prevalence, mortality rates, costs of care and the overall effect on caregivers and society. It also examines the challenges encountered by health care providers when disclosing an AD diagnosis to patients and caregivers. An estimated 5.3 million Americans have AD; 5.1 million are age 65 years, and approximately 200,000 are age <65 years and have younger onset AD. By mid-century, the number of people living with AD in the United States is projected to grow by nearly 10 million, fueled in large part by the aging baby boom generation. Today, someone in the country develops AD every 67 seconds. By 2050, one new case of AD is expected to develop every 33 seconds, resulting in nearly 1 million new cases per year, and the estimated prevalence is expected to range from 11 million to 16 million. In 2013, official death certificates recorded 84,767 deaths from AD, making AD the sixth leading cause of death in the United States and the fifth leading cause of death in Americans age 65 years. Between 2000 and 2013, deaths resulting from heart disease, stroke and prostate cancer decreased 14%, 23% and 11%, respectively, whereas deaths from AD increased 71%. The actual number of deaths to which AD contributes (or deaths with AD) is likely much larger than the number of deaths from AD recorded on death certificates. In 2015, an estimated 700,000 Americans age 65 years will die with AD, and many of them will die from complications caused by AD. In 2014, more than 15 million family members and other unpaid caregivers provided an estimated 17.9 billion hours of care to people with AD and other dementias, a contribution valued at more than $217 billion. Average per-person Medicare payments for services to beneficiaries age 65 years with AD and other dementias are more than two and a half times as great as payments for all beneficiaries without these conditions, and Medicaid payments are 19 times as great. Total payments in 2015 for health care, long-term care and hospice services for people age 65 years with dementia are expected to be $226 billion. Among people with a diagnosis of AD or another dementia, fewer than half report having been told of the diagnosis by their health care provider. Though the benefits of a prompt, clear and accurate disclosure of an AD diagnosis are recognized by the medical profession, improvements to the disclosure process are needed. These improvements may require stronger support systems for health care providers and their patients.

Aging in Place vs. Relocation for Older Adults with Neurocognitive Disorder: Applications of Wiseman's Behavioral Model

Some older adults are more vulnerable to housing concerns due to physical and cognitive challenges, including those with a neurocognitive disorder who need extensive support. Environmental gerontology frameworks, including Wiseman's 1980 Behavioral Model of Elderly Migration, have informed scholarship on aging in place and relocation. Understanding Wiseman's model, including considerations for working with families confronting a neurocognitive disorder, can help practitioners ensure that older clients live in settings that best meet their wants and needs.

The effectiveness of toolkits as knowledge translation strategies for integrating evidence into clinical care: a systematic review

OBJECTIVES

The aim of this systematic review was to evaluate the effectiveness of toolkits as a knowledge translation (KT) strategy for facilitating the implementation of evidence into clinical care. Toolkits include multiple resources for educating and/or facilitating behaviour change.

DESIGN

Systematic review of the literature on toolkits.

METHODS

A search was conducted on MEDLINE, EMBASE, PsycINFO and CINAHL. Studies were included if they evaluated the effectiveness of a toolkit to support the integration of evidence into clinical care, and if the KT goal(s) of the study were to inform, share knowledge, build awareness, change practice, change behaviour, and/or clinical outcomes in healthcare settings, inform policy, or to commercialise an innovation. Screening of studies, assessment of methodological quality and data extraction for the included studies were conducted by at least two reviewers.

RESULTS

39 relevant studies were included for full review; 8 were rated as moderate to strong methodologically with clinical outcomes that could be somewhat attributed to the toolkit. Three of the eight studies evaluated the toolkit as a single KT intervention, while five embedded the toolkit into a multistrategy intervention. Six of the eight toolkits were partially or mostly effective in changing clinical outcomes and six studies reported on implementation outcomes. The types of resources embedded within toolkits varied but included predominantly educational materials.

CONCLUSIONS

Future toolkits should be informed by high-quality evidence and theory, and should be evaluated using rigorous study designs to explain the factors underlying their effectiveness and successful implementation.
