Effects of Self-Management Groups for People with Dementia and Their Spouses--Randomized Controlled Trial

Factors affecting support: experiences of Iranian older spousal caregivers of people with Alzheimer's disease and their support resources

OBJECTIVES

Older spouses are a significant part of family caregivers of patients with Alzheimer's disease (AD) and need support. Evidence suggests that different factors influence the support of older spousal caregivers. However, there is little evidence about these factors in developing countries like Iran. This study aimed to identify the factors affecting the support of Iranian older spousal caregivers of people with AD.

METHOD

This qualitative study used Graneheim and Lundman's conventional content analysis approach. Through purposive sampling, 10 caregivers, three family members, and three professionals were recruited from various cognitive clinics and centers. In-depth and semi-structured interviews were used to collect data and continued until conceptual saturation was achieved.

RESULTS

Two themes were derived from the data as factors affecting support, which included (1) caregiver's support-seeking (complexity of the patient's condition, caregiver's geriatric health, the burden of caring for a spouse with AD, marital bond quality, caregiver's support-phobic beliefs, caregiver's awareness of care) and (2) capacities of support resources (supportive family, supportiveness of society, formal systems' capability to provide support services).

CONCLUSION

The present study provided practical information about the factors influencing the support of older spousal caregivers. Healthcare providers and policymakers can use these concepts to improve the support process by strengthening caregivers' support-seeking motivation and enhancing capacities in support resources.

Self-management Programs Within Rehabilitation Yield Positive Health Outcomes at a Small Increased Cost Compared With Usual Care: A Systematic Review and Meta-analysis

OBJECTIVE

To determine if self-management programs, supported by a health professional, in rehabilitation are cost effective.

DATA SOURCES

Six databases were searched until December 2023.

STUDY SELECTION

Randomized controlled trials with adults completing a supported self-management program while participating in rehabilitation or receiving health professional input in the hospital or community settings were included. Self-management programs were completed outside the structured, supervised therapy and health professional sessions. Included trials had a cost measure and an effectiveness outcome reported, such as health-related quality of life or function. Grading of Recommendations, Assessment, Development, and Evaluations was used to determine the certainty of evidence across trials included in each meta-analysis. Incremental cost-effectiveness ratios were calculated based on the mean difference from the meta-analyses of contributing health care costs and quality of life.

DATA EXTRACTION

After application of the search strategy, two independent reviewers determined eligibility of identified literature, initially by reviewing the title and/or abstract before full-text review. Using a customized form, data were extracted by one reviewer and checked by a second reviewer.

DATA SYNTHESIS

Forty-three trials were included, and 27 had data included in meta-analyses. Where self-management was a primary intervention, there was moderate certainty of a meaningful positive difference in quality-of-life utility index of 0.03 units (95% confidence interval, 0.01-0.06). The cost difference between self-management as the primary intervention and usual care (comprising usual intervention/therapy, minimal intervention [including education only], or no intervention) potentially favored the comparison group (mean difference=Australian dollar [AUD]90; 95% confidence interval, -AUD130 to AUD310). The cost per quality-adjusted life year (QALY) gained for self-management programs as a stand-alone intervention was AUD3000, which was below the acceptable willingness-to-pay threshold in Australia per QALY gained (AUD50,000/QALY gained).

CONCLUSIONS

Self-management as an intervention is low cost and could improve health-related quality of life.

Healthcare interventions for older people with dementia and family caregivers in Europe: A scoping review

AIM

This study aimed to examine the extent, range and variety of research in Europe describing healthcare interventions for older people with dementia (PwD) and family caregivers.

METHODS

This was a scoping review and followed the PRISMA Scoping Review guideline. MEDLINE, CINAHL and Cochrane library databases were searched for studies published between 2010 and 2020. Studies reporting healthcare interventions in Europe for PwD over 65 years and their family caregivers were included.

RESULTS

Twenty-one studies from six European countries were included. The types of healthcare intervention identified were categorized as follows: (1) family unit intervention (interventions for both PwD and their family caregiver), (2) individual intervention (separate interventions for PwD or family caregivers) and (3) family caregiver only intervention (interventions for family caregivers only but with outcomes for both PwD and family caregivers).

CONCLUSIONS

This review provides insight into healthcare interventions for older PwD and family caregivers in Europe. More studies are needed that focus on the family as a unit of care in dementia.

The efficacy of dyadic interventions for community-dwelling people with dementia and their caregivers: A systematic review and meta-analysis

Most people with dementia live at home and depend on informal caregivers for care. Both caregivers and persons with dementia can experience negative psychological and behavioural effects as the disease progresses. Non-pharmacological interventions can alleviate these effects and dyadic interventions, involving both caregiver and person with dementia, may be particularly effective. In this systematic review, the effect of dyadic interventions involving community-dwelling persons with dementia and their informal caregivers was researched. This article is an update of a review of dyadic interventions up to 2012 (Van't Leven et al., 2013). Twenty-two randomized controlled trials published between January 2012 and March 2023 met eligibility criteria, representing 3857 dyads. Results of a meta-analysis showed no overall intervention effect. Thirteen studies reported positive intervention effects, 9 studies reported no intervention effects. Intervention content and participant characteristics and knowledge of the disease varied widely between the studies reviewed. Effective interventions were those that matched activities for the person with dementia to their interests and abilities and educating the caregiver about dementia and communication. Interventions of moderate length (3-4 months) tended to be more effective than longer or shorter interventions. Future studies should further explore the factors contributing to the effects of dyadic interventions.

A systematic review of the social impact of diseases in Nordic countries

BACKGROUND

We review the literature on the social impacts of diseases, defined as the social consequences of having a disease on the people around the patient, such as spouses, caregivers and offspring. The two objectives of this study are to summarise the social outcomes commonly associated with diseases and to compare the social impact across a range of diseases.

METHODS

A systematic review of the social impact of disease in Nordic countries was conducted using PubMed, PsycINFO and Google Scholar (PROSPERO registration number CRD42022291796). All articles that met the inclusion criteria were reviewed. We tabulated all outcomes and diseases studied, and synthesised the evidence based on the perspectives of patients, spouse/caregiver and offspring.

RESULTS

A total of 135 studies met the eligibility criteria, covering 76 diseases and 39 outcomes. From the patient's perspective, diseases impact divorce and marriage rates, social functioning, likelihood of committing a crime and being a victim of crime. From the caregiver's perspective, diseases affect their health-related quality of life and physical and psychological health. From the offspring's perspective, diseases impact their development, health and social adversities in later life. Diseases generally had negative social impacts, but there were some diseases associated with positive impacts.

CONCLUSIONS

The review provides a useful summary and gross comparison of the social impact of different diseases. The social impact of diseases can be large and significant. Thus, it should be considered when policymakers are setting priorities across disease areas.

Health Promotion in Early-Stage Dementia: A Focused Ethnographic Study of a 12-Week Group-Based Educational Intervention

Introduction

Educational health promotion interventions for people with early-stage dementia have shown promising results, including empowering the person with dementia to live well and cope with their condition.

Objectives

The aim of this study was to explore how group interactions, course structure, and facilitation by healthcare professionals in a 12-week educational health promotion course promote coping, healthy behaviors, and empowerment in people with early-stage dementia.

Method

A focused ethnographic approach was employed, collecting data through moderate participant observations of people with early-stage dementia who attended the health promotion course and field conversations with the facilitators. Additionally, before and after the participants had completed the course, the participants and their care partners were interviewed individually.

Results

The findings showed that group discussions provided an opportunity for the facilitators to identify knowledge gaps, correct misinterpretations of symptoms, and tailor the information to the participants' specific needs, thereby promoting healthy behaviors and empowering the participants. The consistent and structured format of the course appeared to reduce stress and promote learning. Learning about dementia first-hand, reminiscing, using humor, receiving support from others facing similar challenges, and receiving support and validation from facilitators all contributed to participants coping with their condition, processing negative emotions, and reducing internalized stigma.

Conclusion

This study emphasized the importance of providing people living with early-stage dementia educational opportunities that combine first-hand information, peer and facilitator support, reminiscing, humor, recognition, and validation. These interventions can contribute to promote coping, healthy behaviors, and empowerment in people living with early-stage dementia.

Cost-Effectiveness of Non-pharmacological Interventions for Mild Cognitive Impairment and Dementia: A Systematic Review of Economic Evaluations and a Review of Reviews

BACKGROUND

Dementia prevalence is increasing, with no cure at present. Drug therapies have potential side effects and risk of mortality. People with dementia are frequently offered non-pharmacological interventions to improve quality of life and relieve symptoms. Identifying which interventions are cost-effective is important due to finite resources in healthcare services.

AIMS

The aims were to review published economic evaluations of community and nursing home non-pharmacological interventions for people with mild cognitive impairment or dementia and assess the usefulness of these evaluations for decision making in health services, for use by policy and local and national decision makers.

METHODS

We conducted a systematic review (PROSPERO CRD42021252999) of economic evaluations of non-pharmacological interventions for dementia or mild cognitive impairment with a narrative approach to data synthesis.

EXCLUSIONS

interventions for dementia prevention/early detection/end of life care. Databases searched: Academic Search Premier, MEDLINE, Web of Science, EMBASE, Google Scholar, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycInfo, Psychology and Behavioural Sciences Collection, PsycArticles, Cochrane Database of Systematic Reviews, Business Source Premier and Regional Business News; timeframe 1 January 2011-11 May 2023. Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS).

RESULTS

The review included 37 economic evaluations and four reviews worldwide across several distinct forms of care: physical activity, cognition, training, multicomponent, assistive technology and other (specialist dementia care, group living, home care vs care home). The intervention with the strongest evidence of cost-effectiveness was maintenance cognitive stimulation therapy. Case management, occupational therapy and dementia care management also showed good evidence of cost-effectiveness.

CONCLUSION

More economic evidence on the cost-effectiveness of specific dementia care interventions is needed, with consistency of methods and outcome measures. This could improve local and national decision makers' confidence to promote future cost-effective dementia interventions.

'I feel more part of the world': Participatory action research to develop post-diagnostic dementia support

Many people living with dementia are 'on the margins', not accessing services and support, despite policy and care advancements. The COVID-19 pandemic exacerbated this, with the closure of face-to-face support during lockdowns in the UK and globally. The aim of the 'Beyond the Margins' project was to develop, implement, and evaluate a face-face programme of support with, by and for people with direct experience of dementia who are on the margins of existing services and support. In March 2020 the project was interrupted by the outbreak of the COVID-19 pandemic and it changed to an online format. The three-phase participatory action research project included 40 people living with dementia, 26 care partners and 31 health and social care practitioners. A seven-week online personal development programme called Getting On with Life (GO) was developed, delivered, and evaluated. This paper focuses on the participatory approaches used to develop and implement the GO programme, and the resulting aspects of its approach to facilitation and content. Key features include the GO Programme's principles of providing a safe and a respectful space, and the programme's values of: Everyone who comes already knows things, can learn things and can teach things; Doing things 'with' each other, rather than 'for' or 'to' each other; Personalised goals-led by the needs of participants rather than an imposed agenda. A key finding was the importance of developing post-diagnostic programmes as a 'sandwich', providing a safe space for learning that is preceded by understanding pathways to access the programme and followed by explicit consideration of the next steps in increasing social engagement.

Cognitive Impairment in Older Adults: Epidemiology, Diagnosis, and Treatment

Cognitive impairment and dementia affect dozens of millions of people worldwide and cause significant distress to patients and caregivers and a financial burden to families and health care systems. Careful history-taking, cognitive and physical examination, and supplemental neuroimaging and fluid-based biomarkers can accurately diagnose neurocognitive disorders. Management includes non-pharmacological and pharmacological treatments tailored to the etiology and to the individual.

The Effectiveness of Multi-Component Interventions on the Positive and Negative Aspects of Well-Being among Informal Caregivers of People with Dementia: A Systematic Review and Meta-Analysis

The present review aims to examine whether multi-component interventions for informal caregivers of people with dementia are effective on positive and negative aspects of caregiver well-being. Eleven databases were searched from inception to 8 March 2021. Only randomized controlled trials reporting the effectiveness of multi-component intervention on positive and negative aspects of caregiver well-being were eligible. Endnote X7 (Thomson ResearchSoft, Stanford, CA, USA) was used for study selection and version 5.1.0 of Cochrane Collaboration's tool (Cochrane, London, UK) was applied for quality assessment. Review Manager (Revman) Version 5.3 (Cochrane, London, UK) was used for the meta-analysis, and if statistical synthesis was inappropriate, only narrative analysis was performed. A total of 31 RCTs with 3939 participants were included. Meta-analyses showed small to moderate effects on subjective well-being, depression, and burden of caregivers, and a moderate to high effect on caregiver anxiety. Due to insufficient data and vast heterogeneity, meta-analysis was not performed for other outcomes, such as resilience, competence, and empathy. This review suggests that individualized multi-component interventions for caregivers may be one of the ways to promote their well-being. Further research is needed to explore the impact of rigorously designed and personalized multi-component interventions on informal caregivers, especially on more positive indicators, as well as its long-term effects and sustainability.

An intervention to promote self-management, independence and self-efficacy in people with early-stage dementia: the Journeying through Dementia RCT

BACKGROUND

There are few effective interventions for dementia.

AIM

To determine the clinical effectiveness and cost-effectiveness of an intervention to promote self-management, independence and self-efficacy in people with early-stage dementia.

OBJECTIVES

To undertake a randomised controlled trial of the Journeying through Dementia intervention compared with usual care, conduct an internal pilot testing feasibility, assess intervention delivery fidelity and undertake a qualitative exploration of participants' experiences.

DESIGN

A pragmatic two-arm individually randomised trial analysed by intention to treat.

PARTICIPANTS

A total of 480 people diagnosed with mild dementia, with capacity to make informed decisions, living in the community and not participating in other studies, and 350 supporters whom they identified, from 13 locations in England, took part.

INTERVENTION

Those randomised to the Journeying through Dementia intervention (n = 241) were invited to take part in 12 weekly facilitated groups and four one-to-one sessions delivered in the community by secondary care staff, in addition to their usual care. The control group (n = 239) received usual care. Usual care included drug treatment, needs assessment and referral to appropriate services. Usual care at each site was recorded.

MAIN OUTCOME MEASURES

The primary outcome was Dementia-Related Quality of Life score at 8 months post randomisation, with higher scores representing higher quality of life. Secondary outcomes included resource use, psychological well-being, self-management, instrumental activities of daily living and health-related quality of life.

RANDOMISATION AND BLINDING

Participants were randomised in a 1 : 1 ratio. Staff conducting outcome assessments were blinded.

DATA SOURCES

Outcome measures were administered in participants' homes at baseline and at 8 and 12 months post randomisation. Interviews were conducted with participants, participating carers and interventionalists.

RESULTS

The mean Dementia-Related Quality of Life score at 8 months was 93.3 (standard deviation 13.0) in the intervention arm (n = 191) and 91.9 (standard deviation 14.6) in the control arm (n = 197), with a difference in means of 0.9 (95% confidence interval -1.2 to 3.0; p = 0.380) after adjustment for covariates. This effect size (0.9) was less than the 4 points defined as clinically meaningful. For other outcomes, a difference was found only for Diener's Flourishing Scale (adjusted mean difference 1.2, 95% confidence interval 0.1 to 2.3), in favour of the intervention (i.e. in a positive direction). The Journeying through Dementia intervention cost £608 more than usual care (95% confidence interval £105 to £1179) and had negligible difference in quality-adjusted life-years (-0.003, 95% confidence interval -0.044 to 0.038). Therefore, the Journeying through Dementia intervention had a mean incremental cost per quality-adjusted life-year of -£202,857 (95% confidence interval -£534,733 to £483,739); however, there is considerable uncertainty around this. Assessed fidelity was good. Interviewed participants described receiving some benefit and a minority benefited greatly. However, negative aspects were also raised by a minority. Seventeen per cent of participants in the intervention arm and 15% of participants in the control arm experienced at least one serious adverse event. None of the serious adverse events were classified as related to the intervention.

LIMITATIONS

Study limitations include recruitment of an active population, delivery challenges and limitations of existing outcome measures.

CONCLUSIONS

The Journeying through Dementia programme is not clinically effective, is unlikely to be cost-effective and cannot be recommended in its existing format.

FUTURE WORK

Research should focus on the creation of new outcome measures to assess well-being in dementia and on using elements of the intervention, such as enabling enactment in the community.

TRIAL REGISTRATION

This trial is registered as ISRCTN17993825.

Psychological treatments for depression and anxiety in dementia and mild cognitive impairment

BACKGROUND

Experiencing anxiety and depression is very common in people living with dementia and mild cognitive impairment (MCI). There is uncertainty about the best treatment approach. Drug treatments may be ineffective and associated with adverse effects. Guidelines recommend psychological treatments. In this updated systematic review, we investigated the effectiveness of different psychological treatment approaches.

OBJECTIVES

Primary objective To assess the clinical effectiveness of psychological interventions in reducing depression and anxiety in people with dementia or MCI. Secondary objectives To determine whether psychological interventions improve individuals' quality of life, cognition, activities of daily living (ADL), and reduce behavioural and psychological symptoms of dementia, and whether they improve caregiver quality of life or reduce caregiver burden.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases, and three trials registers on 18 February 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared a psychological intervention for depression or anxiety with treatment as usual (TAU) or another control intervention in people with dementia or MCI.

DATA COLLECTION AND ANALYSIS

A minimum of two authors worked independently to select trials, extract data, and assess studies for risk of bias. We classified the included psychological interventions as cognitive behavioural therapies (cognitive behavioural therapy (CBT), behavioural activation (BA), problem-solving therapy (PST)); 'third-wave' therapies (such as mindfulness-based cognitive therapy (MBCT)); supportive and counselling therapies; and interpersonal therapies. We compared each class of intervention with control. We expressed treatment effects as standardised mean differences or risk ratios. Where possible, we pooled data using a fixed-effects model. We used GRADE methods to assess the certainty of the evidence behind each result.

MAIN RESULTS

We included 29 studies with 2599 participants. They were all published between 1997 and 2020. There were 15 trials of cognitive behavioural therapies (4 CBT, 8 BA, 3 PST), 11 trials of supportive and counselling therapies, three trials of MBCT, and one of interpersonal therapy. The comparison groups received either usual care, attention-control education, or enhanced usual care incorporating an active control condition that was not a specific psychological treatment. There were 24 trials of people with a diagnosis of dementia, and five trials of people with MCI. Most studies were conducted in community settings. We considered none of the studies to be at low risk of bias in all domains.  Cognitive behavioural therapies (CBT, BA, PST) Cognitive behavioural therapies are probably slightly better than treatment as usual or active control conditions for reducing depressive symptoms (standardised mean difference (SMD) -0.23, 95% CI -0.37 to -0.10; 13 trials, 893 participants; moderate-certainty evidence). They may also increase rates of depression remission at the end of treatment (risk ratio (RR) 1.84, 95% CI 1.18 to 2.88; 2 studies, with one study contributing 2 independent comparisons, 146 participants; low-certainty evidence). We were very uncertain about the effect of cognitive behavioural therapies on anxiety at the end of treatment (SMD -0.03, 95% CI -0.36 to 0.30; 3 trials, 143 participants; very low-certainty evidence). Cognitive behavioural therapies probably improve patient quality of life (SMD 0.31, 95% CI 0.13 to 0.50; 7 trials, 459 participants; moderate-certainty evidence) and activities of daily living at end of treatment compared to treatment as usual or active control (SMD -0.25, 95% CI -0.40 to -0.09; 7 trials, 680 participants; moderate-certainty evidence). Supportive and counselling interventions Meta-analysis showed that supportive and counselling interventions may have little or no effect on depressive symptoms in people with dementia compared to usual care at end of treatment (SMD -0.05, 95% CI -0.18 to 0.07; 9 trials, 994 participants; low-certainty evidence). We were very uncertain about the effects of these treatments on anxiety, which was assessed only in one small pilot study. Other interventions There were very few data and very low-certainty evidence on MBCT and interpersonal therapy, so we were unable to draw any conclusions about the effectiveness of these interventions.

AUTHORS' CONCLUSIONS

CBT-based treatments added to usual care probably slightly reduce symptoms of depression for people with dementia and MCI and may increase rates of remission of depression. There may be important effect modifiers (degree of baseline depression, cognitive diagnosis, or content of the intervention). CBT-based treatments probably also have a small positive effect on quality of life and activities of daily living. Supportive and counselling interventions may not improve symptoms of depression in people with dementia. Effects of both types of treatment on anxiety symptoms are very uncertain. We are also uncertain about the effects of other types of psychological treatments, and about persistence of effects over time. To inform clinical guidelines, future studies should assess detailed components of these interventions and their implementation in different patient populations and in different settings.

Support and Empowerment for Older Adult Spousal Caregiving of People with Mild and Moderate Dementia: A Participatory Action Research

Background: Little attention has been given to the older adult caregivers of spouses with mild and moderate dementia in the caring dynamics process. The aim of this action research was to develop a program for providing support and empowerment to older adult caregivers of spouses with mild and moderate dementia in the community. Methods: The researchers acted as facilitators, with a view to empowering participants. We recruited participants from a day-care center and two community service stations. Data were collected with semi-structured, in-depth interviews with 19 dementia care dyads and from the notes, reflections, and feedback of collaborative researchers. Relevant themes for content analysis were extracted. Results: Three action cycles were completed over 18 months. The results revealed goals of three cycles: to connect the home situation and effective dialogue as a bridge to the researcher, to confirm the daily needs or expectations of the caregiver and the patient, and to enhance the interactions and quality of life of family members with resources and network. This process was cyclical and repetitive, and it also generated partnerships that built relationships among the interdisciplinary team, families, and researchers. At the same time, team workers formed a cooperative and coordinated family service mechanism to reflect the professional values and practice capabilities. Conclusions: The intervention program was based on the promotion of factors for the caregiver, linking to environmental protective factors, and the stabilization of mental and neurological symptoms of dementia patients, thereby enhancing the response capabilities of home caregivers while meeting the patient’s care needs in life. It is a tool that can effectively be used for support and empowerment in this population.

Factors Influencing the Quality of Life of the Primary Caregiver of a Palliative Patient: Narrative Review

Introduction: Quality of life is a difficult concept to understand and therefore difficult to evaluate. From the general definition to the individuality of the person, there are factors that positively or negatively influence quality of life. Aim: The aim is to identify the factors that influence the quality of life of primary caregivers of patients with progressive life-threatening illnesses. Methodology: PUBMED was searched to retrieve the relevant literature for our research questions used the following keywords: "Quality of life and caregiver or caretaker and palliative care or life threatening disease." Only quantitative studies containing randomized trials were included using at least one caregiver's quality-of-life tool, not older than 10 years, written in English, and with subjects older than 18 years, who considered they were involved in the active care of a palliative patient. Results: A number of 687 articles were identified from which only 38 were analyzed in detail regarding the impact of different interventions over the quality-of-life of the caregiver. The factors that influence the quality-of-life can be distributed into four areas: social, psycho-emotional, financial, and physical. The disruption of daily routine, non-existential financial resources, multiple responsibilities and psychological tension are reduce the caregiver's quality-of-life. Family involvment, knowledge about disease and treatment, abilities to communicate patient and the team and optimistic atitude improve caregiver's quality-of-life. Conclusions: The quality of life of the caregiver be improved by social, and relaxation techniques, reduction of insecurity or anxiety. Furthermore, the caregiver's quality of increases through and adequate communication diagnosis, a proper conducted treatment and education over the care maneuvers.

Supporting Informal Caregivers of People With Dementia in Cost-Effective Ways: A Systematic Review and Meta-Analysis

OBJECTIVES

Caring for persons with dementia is a heavy burden for informal caregivers. This study aimed to appraise the economic evidence of interventions supporting informal caregivers of people with dementia.

METHODS

Literature was searched, and trial-based studies evaluating the costs and effects of interventions supporting informal caregivers of people with dementia were included. Cost data were analyzed from both healthcare and societal perspectives. Random-effects models were used to synthesize cost and effect data, based on mean differences (MDs) or standardized MDs.

RESULTS

Of 33 eligible studies identified from 48 588 records, 14 (42.4%) showed net savings in total cost regardless of analytical perspectives. Among 22 studies included in meta-analyses, caregiver-focused psychosocial interventions showed improvements in caregivers' psychological health (n = 4; standardized MD 0.240; 95% confidence interval 0.094-0.387); nevertheless, the increases in societal cost were significant (n = 5; MD 3144; 95% confidence interval 922-5366). Psychological intervention and behavioral management engaging patient-caregiver dyads showed positive effects on caregivers' subjective burden, also with increases in total cost. Subgroup analyses indicated that the inclusion of different intervention components, the caregiver characteristics, and the follow-up periods could affect the costs and effects of interventions supporting informal caregivers.

CONCLUSIONS

Psychosocial interventions directed at informal caregivers and dyad-based psychological and behavioral interventions are effective but also expensive. The use of these interventions depends on the society's willingness to pay. More comprehensive economic evidence of interventions supporting informal caregivers is required, and the design of intervention should focus more on different intervention components, characteristics of patients and caregivers, and healthcare systems.

Self-Management of Dementia by Family Carers: A Scoping Review

Family carers increasingly take on the responsibility of self-management of dementia as the condition progresses. However, research on this topic is scarce. This scoping review aimed to identify the key characteristics related to self-management of dementia by carers including its components, theoretical/conceptual frameworks that underpinned these components and measurements. A scoping review was conducted in 8 databases and 16 publications met the inclusion criteria. Twenty-two components were identified and grouped into two categories: activities and carer characteristics and skills. The identified theoretical/conceptual frameworks were numerous and varied as were the measures. There was a little consistency of the key characteristics of self-management of dementia by carers. The findings assist carers and healthcare providers to understand the components involved in self-managing dementia which will guide the development and delivery of self-management support interventions for carers. Further research is required to validate these findings and to develop specialized conceptual frameworks and measures.

Monetary value of informal caregiving in dementia from a societal perspective

BACKGROUND

Dementia is a condition which results in a high cost of care, a significant proportion of which is the cost associated with informal care. In previous studies, informal caregiving has been challenging to assess due to difficulties in estimating the true time spent on caregiving work and how to value caregivers' time. The aim of this study was to compare the costs of dementia among patients living alone and among those living with a caregiver to show the monetary value of informal caregiving from a societal perspective.

METHODS

Data from our four dementia trials using the same measures were combined, allowing the inclusion of 604 participants. Participants were followed up for 2 years or until death for their use of health and social services. Use of all services was retrieved from medical/social records. We also included the costs of lost productivity of those caregivers who were not retired.

RESULTS

The total mean cost of services and lost productivity was €22,068/person-year (pyrs). Participants living alone had a mean cost of €45,156/pyrs, whereas those living with a spouse had a mean cost of €16,416/pyrs (mean cost ratio 2.99, 95% confidence interval 2.64-3.39). Participants living alone and having <15 Mini-Mental State Examination points had higher costs than people with dementia in institutional care.

CONCLUSIONS

Detailed data of service use and characteristics of people with dementia showed that from a societal perspective, living alone is a very strong determinant of service use in dementia. Informal caregivers do invaluable work for society.

"Taking care of myself as long as I can": How People with Dementia Configure Self-Management Systems

Self-management research in HCI has addressed a variety of conditions. Yet, this literature has largely focused on neurotypical populations and chronic conditions that can be managed, leaving open questions of what self-management might look like for populations with progressive cognitive impairment. Grounded in interviews with seventeen technology savvy people with mild to moderate dementia, our analysis reveals their use of technological and social resources as part of the work of self-management. We detail how participants design self-management systems to enable desired futures, function well in their social world, and maintain control. Our discussion broadens the notion of self-management to include future-oriented, sociotechnical, self-determinate design. We advocate for expanding the way technologists, designers, and HCI scholars view people with mild to moderate dementia to recognize them as inventive creators and capable actors in self-management.

Psychosocial interventions to support the mental health of informal caregivers of persons living with dementia - a systematic literature review

Background

Informal caregivers of persons living with dementia have an increased risk of adverse mental health effects. It is therefore important to systematically summarize published literature in order to find out which mental health interventions generate effective support for informal caregivers of persons living with dementia. The objective of this study is to conduct a systematic review of intervention content, effectiveness and subgroup differentiation of mental health interventions for informal caregivers of persons with dementia living at home.

Method

We searched four electronic databases (PubMed, PsychINFO, Scopus and CINAHL) and included only methodically high-quality randomized controlled trials (RCTs), published in English or German language between 2009 and 2018. The intervention programmes focused on mental health of family caregivers. A narrative synthesis of the included studies is given.

Results

Forty-eight publications relating to 46 intervention programmes met the inclusion criteria. Burden, depression and quality of life (QoL) are the predominant parameters that were investigated. Twenty-five of forty-six interventions (54.3%) show positive effects on at least one of the outcomes examined. Most often, positive effects are reported for the outcome subjective burden (46.2%). Only six studies explicitly target on a certain subgroup of informal dementia caregivers (13%), whereas all other interventions (87%) target the group as a whole without differentiation.

Conclusion

The most beneficial results were found for cognitive behavioural approaches, especially concerning the reduction of depressive symptoms. Besides this, leisure and physical activity interventions show some good results in reducing subjective caregiver burden. In order to improve effectiveness, research and practice may focus on developing more targeted interventions for special dementia informal caregiver subgroups.

Health promotion intervention for people with early-stage dementia: A quasi-experimental study

INTRODUCTION

With the limited advancements in medical treatment, there is a growing need for supporting people with early-stage dementia adjust to their diagnosis and improve their quality of life. This study aimed to investigate the effects of a 12-week health promotion course for people with early-stage dementia.

METHODS

Quasi-experimental, single group, pretest-posttest design. A total of 108 persons with dementia participated in this study, and for each participant, a carer was interviewed. The 12-week health promotion intervention consisted of 2-hr sessions at weekly intervals. Outcome measures were cognition, measured by Mini-Mental State Examination, personal, and instrumental activities of daily living (P-ADL and I-ADL), measured by Lawton and Brody's Physical Self-Maintenance Scale and Instrumental Activities of Daily Living Scale, self-rated health, measured by the European Quality of life Visual Analogue Scale, depressive symptoms, measured by the Cornell Scale for Depression in Dementia, and neuropsychiatric symptoms, measured by The Neuropsychiatric Inventory. Assessments were conducted at baseline and at follow-up 1-2 months postintervention.

RESULTS

The results demonstrate a small but statistically significant improvement in depressive symptoms (p = .015) and in self-rated health (p = .031). The results also demonstrated a small statistically significant decline in the participants' I-ADL (p = .007). The participants' cognitive function, P-ADL, and neuropsychiatric symptoms were stable during the 4-month follow-up.

CONCLUSION

This study demonstrates promising results with regard to the benefit of attending a 12-week health promotion intervention in promoting health and well-being in people with early-stage dementia. With the majority of participants with early-stage dementia living at home without any healthcare services in a vulnerable stage of the condition, this study makes an important contribution to highlighting the need for, and benefit of, educational approaches for this population.

Self-management and cognitive rehabilitation in early stage dementia - merging methods to promote coping and adoption of assistive technology. A pilot study

Objectives: It is essential to develop interventions that meet individual needs for coping and self-management of people with dementia. This study explored the feasibility and applicability of an intervention merging methods of cognitive rehabilitation and self-management groups for people with early stage dementia. The potential of this intervention to promote adoption of assistive technology was also explored.Method: People with early stage Alzheimer's disease (N = 19) participated in the programme comprising both individual and group sessions. Caregivers were involved in the individual session and a separate group meeting. The intervention both addressed individual goals and more general self-management approaches. In addition, both participants and caregivers were introduced to the ReACT app, a holistic solution tailormade to meet self-management needs of people with early stage dementia.Results: There was significant improvement in the participants' attainment of individual goals and satisfaction with goal attainment from pre- to post-intervention. Participants and caregivers generally reported a positive attitude towards the intervention, attendance rate was high, and all participants completed the intervention. Qualitative results also indicated that the intervention promoted awareness, acceptance and coping among participants. The specific benefits of using the ReACT app for self-management were also emphasised. Forty-two percent of the participants adopted the app and continued using it after completing the intervention.Conclusion: Results from this pilot study indicated that the intervention is both feasible and applicable and can be an effective method to promote coping and adoption of assistive technology among people with early stage dementia.

Self-management and HeAlth Promotion in Early-stage dementia with e-learning for carers (SHAPE): study protocol for a multi-centre randomised controlled trial

BACKGROUND

With an increasing number of people with dementia worldwide and limited advancement in medical treatments, the call for new and cost-effective approaches is crucial. The utility of self-management has been proven in certain chronic conditions. However, very little work has been undertaken regarding self-management in people with dementia.

METHODS

The SHAPE trial will include 372 people with mild to moderate dementia to evaluate the effectiveness and cost-effectiveness of an educational programme combining approaches of self-management, health promotion, and e-learning for care partners. The study is a multi-site, single-randomised, controlled, single-blinded trial with parallel arms. The intervention arm is compared with treatment as usual. The intervention comprises a 10-week course delivered as group sessions for the participants with dementia. The sessions are designed to develop self-management skills and to provide information on the nature of the condition and the development of healthy behaviours in a supportive learning environment. An e-learning course will be provided for care partners which covers similar and complementary material to that discussed in the group sessions for the participant with dementia.

DISCUSSION

This trial will explore the effect of the SHAPE group intervention on people with mild to moderate dementia in terms of self-efficacy and improvement in key health and mental health outcomes and cost-effectiveness, along with carer stress and knowledge of dementia.

Practicing in a person-centred environment - self-help groups in psycho-social rehabilitation

AIM

The increasing prevalence of chronic conditions and impairments in the population is putting new demands on health and rehabilitation services. Research on self-help groups suggest that participation in these groups might have a positive impact on people who are struggling with chronic illnesses or disabilities. In this study, we explore person-centred support in which participants in self-help groups are undergoing rehabilitation to develop their knowledge, skills and confidence necessary to handle life's challenges.

METHOD

The design is exploratory, analysing data from informant interviews and focus groups (a total of 32 participants) using a Grounded Theory inspired approach to analyse. The participants were rehabilitation clients aged between 20 and 60 years; eight were men and twenty-six were women.

RESULTS

Three main categories emerged as being important self-help processes that were likely to promote positive rehabilitation outcomes: (1) Learning and practicing safely, (2) A refuge from expectations, (3) Internal processes that accentuate the positives.

CONCLUSION

Peer support delivered through the structured self-help environment can facilitate the development of new self-awareness, promote acceptance and adjustment, facilitate the establishment of new skills and enable transfer of learning to new environments, including the workplace.IMPLICATIONS FOR REHABILITATIONSelf-help groups may support the process of rehabilitation.Participating in self-help groups provides an enabling context for individuals to address challenges and limitations.Peer support delivered through the structured self-help environment can facilitate the development of new self-awareness, promote adjustment, and facilitate the establishment of new skills.Participating in peer led self-help groups can assist with the transfer of learning to new environments, including development of potential work capacity.

What is known from the existing literature about peer support interventions for carers of individuals living with dementia: A scoping review

This scoping review comprehensively describes evidence of using peer support to assist informal carers of individuals with dementia (any type). A systematic search of 11 databases (CINAHL, Cochrane Library, Medline, Embase, PsychInfo, Web of Science, Scopus, Science Direct, ProQuest, TRIP and PubMed) was conducted for research published between 2007-2017 focussing on informal dementia carers, and research designs with interventions incorporating or consisting exclusively of peer support. Authors worked independently to screen retrieved articles, review applicability and extract data. Thirty-six research papers (representing 28 original studies) were identified, from these, two modes of delivery were demonstrated: 12 studies provided the intervention online, and the remainder face-to-face. The review indicated that peer support is of potential benefit to carers if it is delivered via either mode. It is not clear what components may or may not be effective as results provided a mixed landscape of differing intervention effectiveness due to the wide variation in outcome measurements. Trial design using a multi-component intervention was the predominant choice, with the most common components being Information Sharing and Non-Healthcare Professional Support for both delivery modes. The burden/anxiety/depression compendium and health and well-being were the most frequently measured outcomes; perceived level of support was one of the least. The peer support interventions identified included various components, demonstrating no true best practice model. Nonetheless, they can be offered successfully online or face-to-face. This provides a unique opportunity to develop and supply tailored peer support interventions for informal dementia carers to ensure their specific needs are met. Further work is required to construct and evaluate the effectiveness of targeted peer-led support whether online or face-to-face to meet the individual needs of dementia carers.

Acceptability and feasibility of a Japanese version of STrAtegies for RelaTives (START-J): A manualized coping strategy program for family caregivers of relatives living with dementia

The rising older population in Japan is associated with a rise in cases of dementia. Support for the increased number of family caregivers of people living with dementia is crucial, as caring may negatively affect a family caregiver's health. This study seeks to evaluate the feasibility and applicability of a recently developed Japanese version of START (STrAtegies for RelaTives). START is a psychosocial coping intervention program developed in the United Kingdom that has been shown to improve caregivers' mood and quality of life in a randomized controlled trial. We made changes to START (e.g., idioms, linguistic nuance, and providing care insurance information suited for Japan) to make it culturally appropriate. Fourteen Japanese female family caregivers of relatives with mild dementia (n = 10) or mild cognitive impairment (n = 4) were referred to the study, but six were excluded owing to illness and busyness. This single-arm study had a before-after trial evaluating psychological outcomes including depression, anxiety, quality of life, and subjective care burden. The acceptance retention and satisfaction rate suggest the feasibility and acceptability of the START program; 8/14 (>55%) eligible, prospective participants consented and were included in this study, all (8/8) of whom completed all START sessions. The mean program satisfaction score was 30.25 (standard deviation = 2.25) out of a potential 32. The results suggest that it is feasible and acceptable to deliver START in Japanese and based on the results of analysis using a linear mixed model, there is initial indication that the intervention improved family caregivers' quality of life, depressive symptoms, and care burden.

Healthy together: A systematic review of theory and techniques used in health interventions for persons with chronic neurological conditions and their caregivers

OBJECTIVE

To evaluate the level of theory application and use of behaviour change techniques (BCTs) in dyadic health interventions for persons with chronic neurological conditions (CNCs) and their caregivers.

METHODS

A systematic review of five databases was conducted to locate articles published before January 2019. Methodological quality was assessed, study characteristics, theory application and BCTs were narratively summarized.

RESULTS

More than half of the studies identified (59% [16/27]) did not mention theory, and only 22% (6/27) were explicitly theory-based. Across the 27 studies, two to 17 BCTs (mean = 6.8 ± 4.02) were used. Common BCTs were related to intervention implementation (e.g., credible source), knowledge (e.g., instruction on how to perform behaviour) and skill development (e.g., behavioural practice/rehearsal).

CONCLUSIONS

Researchers need to incorporate theory-based dyadic techniques that target both people with CNCs and their caregivers into the design and implementation of future health interventions.

PRACTICE IMPLICATIONS

Health professionals require explicitly theory-based interventions to provide dyads with CNCs techniques that they can apply in their daily life to the benefit of each individual and the partnership.

Screening for Cognitive Impairment in Older Adults: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Early identification of cognitive impairment may improve patient and caregiver health outcomes.

OBJECTIVE

To systematically review the test accuracy of cognitive screening instruments and benefits and harms of interventions to treat cognitive impairment in older adults (≥65 years) to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMed, PsycINFO, and Cochrane Central Register of Controlled Trials through January 2019, with literature surveillance through November 22, 2019.

STUDY SELECTION

Fair- to good-quality English-language studies of cognitive impairment screening instruments, and pharmacologic and nonpharmacologic treatments aimed at persons with mild cognitive impairment (MCI), mild to moderate dementia, or their caregivers.

DATA EXTRACTION AND SYNTHESIS

Independent critical appraisal and data abstraction; random-effects meta-analyses and qualitative synthesis.

MAIN OUTCOMES AND MEASURES

Sensitivity, specificity; patient, caregiver, and clinician decision-making; patient function, quality of life, and neuropsychiatric symptoms; caregiver burden and well-being.

RESULTS

The review included 287 studies with more than 280 000 older adults. One randomized clinical trial (RCT) (n = 4005) examined the direct effect of screening for cognitive impairment on patient outcomes, including potential harms, finding no significant differences in health-related quality of life at 12 months (effect size, 0.009 [95% CI, -0.063 to 0.080]). Fifty-nine studies (n = 38 531) addressed the accuracy of 49 screening instruments to detect cognitive impairment. The Mini-Mental State Examination was the most-studied instrument, with a pooled sensitivity of 0.89 (95% CI, 0.85 to 0.92) and specificity of 0.89 (95% CI, 0.85 to 0.93) to detect dementia using a cutoff of 23 or less or 24 or less (15 studies, n = 12 796). Two hundred twenty-four RCTs and 3 observational studies including more than 240 000 patients or caregivers addressed the treatment of MCI or mild to moderate dementia. None of the treatment trials were linked with a screening program; in all cases, participants were persons with known cognitive impairment. Medications approved to treat Alzheimer disease (donepezil, galantamine, rivastigmine, and memantine) improved scores on the ADAS-Cog 11 by 1 to 2.5 points over 3 months to 3 years. Psychoeducation interventions for caregivers resulted in a small benefit for caregiver burden (standardized mean difference, -0.24 [95% CI, -0.36 to -0.13) over 3 to 12 months. Intervention benefits were small and of uncertain clinical importance.

CONCLUSIONS AND RELEVANCE

Screening instruments can adequately detect cognitive impairment. There is no empirical evidence, however, that screening for cognitive impairment improves patient or caregiver outcomes or causes harm. It remains unclear whether interventions for patients or caregivers provide clinically important benefits for older adults with earlier detected cognitive impairment or their caregivers.

Developing the New Interventions for independence in Dementia Study (NIDUS) theoretical model for supporting people to live well with dementia at home for longer: a systematic review of theoretical models and Randomised Controlled Trial evidence

PURPOSE

To build an evidence-informed theoretical model describing how to support people with dementia to live well or for longer at home.

METHODS

We searched electronic databases to August 2018 for papers meeting predetermined inclusion criteria in two reviews that informed our model. We scoped literature for theoretical models of how to enable people with dementia to live at home independently, with good life quality or for longer. We systematically reviewed Randomised Controlled Trials (RCTs) reporting psychosocial intervention effects on time lived with dementia at home. Two researchers independently rated risk of bias. We developed our theoretical model through discussions with experts by personal, clinical and academic experiences, informed by this evidence base.

RESULTS

Our scoping review included 52 studies. We divided models identified into: values and approaches (relational and recovery models; optimising environment and activities; family carer skills and support); care strategies (family carer-focused; needs and goal-based; self-management); and service models (case management; integrated; consumer-directed). The 11 RCTs included in our systematic review, all judged at low risk of bias, described only two interventions that increased time people with dementia lived in their own homes. These collectively encompassed all these components except for consumer-directed and integrated care. We developed and revised our model, using review evidence and expert consultation to define the final model.

CONCLUSIONS

Our theoretical model describes values, care strategies and service models that can be used in the design of interventions to enable people with dementia to live well and for longer at home.

Loneliness in assisted living facilities: An exploration of the group process

BACKGROUND

More than one in three older people in assisted living facilities suffer from loneliness that leads to adverse health outcomes. Group work may have the potential to improve residents' quality of life.

AIMS/OBJECTIVES

The purpose of this feasibility study was to thoroughly describe a facilitated group process and compare its effects on cognitively impaired (n = 6) and cognitively intact (n = 7) lonely resident groups in assisted living facilities.

MATERIAL AND METHODS

We used a closed, occupational therapy-oriented group model designed for lonely people. The study used a qualitative, multi-method approach. Material included individual and focus group interviews, observations and the facilitators' field diaries.

RESULTS

Loneliness was reflected in diverse ways in both groups. Meaningful activities in mutual interaction played an important role in empowering the participants and enabling the development of the group process. Group processes had similar, parallel steps, from which the participants seemed to benefit. Surprisingly, the cognitively impaired group progressed towards self-direction more quickly than the cognitively intact group.

CONCLUSIONS

A group process with clearly progressing steps revealed that lonely older people are capable of empowerment and self-direction - despite their frailty and cognitive impairment. Facilitators should be familiar with group processes to enable them to progress effectively.

Diagnosis and Management of Dementia: Review

Importance

Worldwide, 47 million people live with dementia and, by 2050, the number is expected to increase to 131 million.

Observations

Dementia is an acquired loss of cognition in multiple cognitive domains sufficiently severe to affect social or occupational function. In the United States, Alzheimer disease, one cause of dementia, affects 5.8 million people. Dementia is commonly associated with more than 1 neuropathology, usually Alzheimer disease with cerebrovascular pathology. Diagnosing dementia requires a history evaluating for cognitive decline and impairment in daily activities, with corroboration from a close friend or family member, in addition to a thorough mental status examination by a clinician to delineate impairments in memory, language, attention, visuospatial cognition such as spatial orientation, executive function, and mood. Brief cognitive impairment screening questionnaires can assist in initiating and organizing the cognitive assessment. However, if the assessment is inconclusive (eg, symptoms present, but normal examination findings), neuropsychological testing can help determine whether dementia is present. Physical examination may help identify the etiology of dementia. For example, focal neurologic abnormalities suggest stroke. Brain neuroimaging may demonstrate structural changes including, but not limited to, focal atrophy, infarcts, and tumor, that may not be identified on physical examination. Additional evaluation with cerebrospinal fluid assays or genetic testing may be considered in atypical dementia cases, such as age of onset younger than 65 years, rapid symptom onset, and/or impairment in multiple cognitive domains but not episodic memory. For treatment, patients may benefit from nonpharmacologic approaches, including cognitively engaging activities such as reading, physical exercise such as walking, and socialization such as family gatherings. Pharmacologic approaches can provide modest symptomatic relief. For Alzheimer disease, this includes an acetylcholinesterase inhibitor such as donepezil for mild to severe dementia, and memantine (used alone or as an add-on therapy) for moderate to severe dementia. Rivastigmine can be used to treat symptomatic Parkinson disease dementia.

Conclusions and Relevance

Alzheimer disease currently affects 5.8 million persons in the United States and is a common cause of dementia, which is usually accompanied by other neuropathology, often cerebrovascular disease such as brain infarcts. Causes of dementia can be diagnosed by medical history, cognitive and physical examination, laboratory testing, and brain imaging. Management should include both nonpharmacologic and pharmacologic approaches, although efficacy of available treatments remains limited.

Can non-pharmacological interventions reduce hospital admissions in people with dementia? A systematic review

Background

People with dementia who are admitted to hospital have worse outcomes than those without dementia. Identifying interventions that could reduce the risk of hospitalisation in people with dementia has the potential to positively impact on lives of people with dementia. This review aimed to investigate whether there are non-pharmacological interventions that successfully reduce hospitalisation risk, length of stay and mortality in people with dementia.

Methods

7 electronic databases and trial registries were searched from inception to October 2018. We included randomised controlled trials that evaluated non-pharmacological interventions in out of hospital settings and targeted people with any type of dementia. All stages of the review process were performed by two reviewers. Risk of bias was assessed using the Cochrane Risk of Bias tool. We grouped studies based on intervention: care management, counselling/self-help, enhanced GP services or memory clinics, and physiotherapy or occupational therapy. Data were pooled within intervention categories using random effects meta-analysis.

Results

There was no evidence that any of the intervention categories were associated with reduced hospital admission or mortality. There was very weak evidence to suggest that care management interventions (mean difference, MD, -0.16, 95% CI -0.32, 0.01), physiotherapy/occupational therapy (MD -0.16, 95% CI -0.36, 0.03) and enhanced GP/memory clinics (MD -0.14, 95% CI -0.31, 0.03) were associated with small reductions in hospital stay. There was no evidence for an effect of counselling/self-help interventions on length of hospital stay.

Conclusions

Current evidence from randomised trials suggests no clear benefit or harm associated with any of interventions on risks of hospitalisation, duration of hospitalisation or death. Further research with the primary aim to reduce hospitalisation in people with dementia is required.

Impact of health service interventions on acute hospital use in community-dwelling persons with dementia: A systematic literature review and meta-analysis

Background

Persons with dementia have twice the acute hospital use as older persons without dementia. In addition to straining overburdened healthcare systems, acute hospital use impacts patient and caregiver quality of life and is associated with increased risk of adverse outcomes including death. Reducing avoidable acute hospital use in persons with dementia is thus a global healthcare priority. However, evidence regarding the impact of health service interventions as defined by the Effective Practice and Organization of Care Cochrane Group on acute hospital use is scant and inconclusive. The aim of this systematic review and meta-analysis was to synthesize available evidence on the impact of health service interventions on acute hospital use in community-dwelling persons with dementia compared to usual care.

Methods

Data Sources: MEDLINE, EMBASE, CINAHL and Cochrane CENTRAL (from 01/1995 to 08/2017). Study eligibility criteria: Randomised controlled trials measuring the impact of health service interventions on acute hospital use (proportion and mean number of emergency department visits and hospitalisations, mean number of hospital days, measured at 12 months, and at longest follow-up) in community-dwelling persons with dementia, compared to usual care. Study selection, appraisal and synthesis methods: Reviewers independently identified studies, extracted data, and assessed the risk of bias, with the Cochrane risk of bias tool. Authors of relevant trials were queried about unpublished data. Random effects model was used for meta-analyses. Effect heterogeneity was assessed through prediction intervals, and explored using sub-group analyses.

Findings

Seventeen trials provided data on 4,549 persons. Unpublished data were obtained for 13 trials, representing 65% of synthesized data. Most interventions included a case management or a self-management component. None of the outcome comparisons provided conclusive evidence supporting the hypothesis that these interventions would lead to a decrease in acute hospital use. Furthermore, prediction intervals indicated possible and important increased service use associated with these interventions, such as emergency department visits, hospital admissions, and hospital days. Subgroup analyses did not favour any type of intervention. A limitation of this study is the inclusion of any type of health service intervention, which may have increased the observed heterogeneity.

Conclusion

Despite a comprehensive systematic review and meta-analysis, including predominantly unpublished data, no health service intervention beyond usual care was found to reduce acute hospital use in community-dwelling persons with dementia. An important increase in service use may be associated with these interventions. Further research is urgently needed to identify effective interventions for this vulnerable population to limit rising acute hospital use, associated costs and adverse outcomes.

Rehabilitation for People Living with Dementia: A Scoping Review of Processes and Outcomes

Objectives

The aim of this scoping review was to map intervention studies of rehabilitation for people living with dementia regarding processes and outcomes, with a particular focus on whether the intervention is person-centred, home-based, or organised adopting a multidisciplinary approach and measures outcomes relating to everyday functioning and well-being.

Methods

A systematic search of electronic databases was conducted in PubMed, CINAHL, PsycINFO, Embase, and Cochrane. Studies from 2005 to November 2018 were collected and screened for relevance and quality. Randomised control trials and prospective cohort trials reporting a statistically significant effect on one or more outcome measures were included. Included studies were mapped according to selected processes and outcome measures.

Results

Twenty-six intervention studies were included and mapped. Nineteen of the interventions were person-centred, nine were home-based, and 14 reported a multidisciplinary approach. Twelve of the interventions had activities of daily living as an outcome measure, and 14 had quality of life as an outcome measure.

Conclusion

Person-centredness appears in most rehabilitation interventions for people living with dementia. Other processes and outcomes are heterogeneously described in the research literature. Rehabilitation programmes can be home-based or take place at a centre. Although not exclusive, the organisation of rehabilitation can be multidisciplinary. Fewer than half of the intervention studies measure the impact on activities of daily living and quality of life. Future guidelines must take into account the weak evidence regarding these aspects.

Psychosocial Interventions for Community-Dwelling People Following Diagnosis of Mild to Moderate Dementia: Findings of a Systematic Scoping Review

National policies and evidence reviews recommend psychosocial interventions (PIs) as an essential support, particularly in the period following dementia diagnosis. However, availability and uptake of these interventions are comparatively low. One of the reasons for this is that clinicians lack information about what might be provided and the potential benefits of different interventions. This article identifies and describes PIs for community-dwelling people following diagnosis of mild to moderate dementia and presents the available evidence to inform practice decisions. A systematic scoping review was employed to map the evidence relating to PIs for this group. This identified 63 relevant studies, testing 69 interventions, which could be grouped into 6 intervention categories: 20 cognition-oriented, 11 behavior-oriented, 11 stimulation-oriented, 13 emotion-oriented, 5 social-oriented, and 9 multimodal. There were three targets for outcome measurement of these PIs: the person with dementia, the family caregiver, and the person-caregiver dyad. Over 154 outcome measures were identified in the studies, with outcomes measured across 11 main domains. The lack of a classification framework for PIs means it is difficult to create a meaningful synthesis of the breadth of relevant evidence to guide clinical practice. Possible dimensions of a classification framework are proposed to begin to address this gap.

Effects of preventive home visits on health-related quality-of-life and mortality in home-dwelling older adults

OBJECTIVE

We explored the effectiveness of preventive home visits on the health-related quality-of-life (HRQoL) and mortality among independently community-dwelling older adults.

DESIGN

A randomised controlled trial.

SUBJECTS

Independently home-dwelling older adults 75 years and older, consisting of 211 in the intervention and 211 in the control group.

SETTING

Hyvinkää town municipality, Finland.

MAIN OUTCOME MEASURES

We used the change in HRQoL measured by the 15D scale as our primary outcome. Mortality at two years was retrieved from central registers.

RESULTS

At the one-year time point, the HRQoL according to the 15D scores deteriorated in the control group, whereas we found no change in the intervention group. The difference between the 15D score changes between the groups was -0.015 (95% CI -0.029 to -0.0016; p = 0.028, adjusted for age, sex, and baseline value). At the two-year time point as the visits ended, that difference diminished. There was no difference in mortality between the groups during the 24-month follow-up.

CONCLUSION

Preventive home visits implemented by a multidisciplinary team with CGA appear to help slow down the decline in HRQoL among older adults, although the effect diminishes when the visits end. Key points We are exploring preventive home visits as means to support the health-related quality-of-life (HRQoL) of home-dwelling older adults Multiprofessional preventive home visits in this intervention study helped to maintain the HRQoL when measured using 15D The effects on HRQoL diminished when the intervention ended, so could further benefits be attained with a longer intervention?The clinical trial registration number: ACTRN12616001411437.

Living Life and Doing Things Together: Collaborative Research With Couples Where One Partner Has a Diagnosis of Dementia

The aim of this study is to identify relevant content for a self-management guide by using the outcomes of previous research in combination with knowledge and experiences from couples where one partner has a diagnosis of dementia. The study was carried out in three phases: (a) literature search of previous research related to well-being and couplehood in dementia; (b) interviews with couples with dementia based on the findings of the literature search; and (c) further authentication of the findings within expert groups of people with dementia and carers. For analysis of data, we used a hybrid approach of thematic analysis with combined deductive and inductive approaches. The findings of this study indicated that the four main themes "Home and Neighborhood," "Meaningful Activities and Relationships," "Approach and Empowerment," and "Couplehood" with related subthemes could be appropriate targets for a self-management guide for couples where one partner has a diagnosis of dementia.

Managing diabetes in people with dementia: a realist review

BACKGROUND

Dementia and diabetes mellitus are common long-term conditions that coexist in a large number of older people. People living with dementia and diabetes may be at increased risk of complications such as hypoglycaemic episodes because they are less able to manage their diabetes.

OBJECTIVES

To identify the key features or mechanisms of programmes that aim to improve the management of diabetes in people with dementia and to identify areas needing further research.

DESIGN

Realist review, using an iterative, stakeholder-driven, four-stage approach. This involved scoping the literature and conducting stakeholder interviews to develop initial programme theories, systematic searches of the evidence to test and develop the theories, and the validation of programme theories with a purposive sample of stakeholders.

PARTICIPANTS

Twenty-six stakeholders (user/patient representatives, dementia care providers, clinicians specialising in dementia or diabetes and researchers) took part in interviews and 24 participated in a consensus conference.

DATA SOURCES

The following databases were searched from 1990 to March 2016: MEDLINE (PubMed), Cumulative Index to Nursing and Allied Health Literature, Scopus, The Cochrane Library (including the Cochrane Database of Systematic Reviews), Database of Abstracts of Reviews of Effects, the Health Technology Assessment (HTA) database, NHS Economic Evaluation Database, AgeInfo (Centre for Policy on Ageing - UK), Social Care Online, the National Institute for Health Research (NIHR) portfolio database, NHS Evidence, Google (Google Inc., Mountain View, CA, USA) and Google Scholar (Google Inc., Mountain View, CA, USA).

RESULTS

We included 89 papers. Ten papers focused directly on people living with dementia and diabetes, and the rest related to people with dementia or diabetes or other long-term conditions. We identified six context-mechanism-outcome (CMO) configurations that provide an explanatory account of how interventions might work to improve the management of diabetes in people living with dementia. This includes embedding positive attitudes towards people living with dementia, person-centred approaches to care planning, developing skills to provide tailored and flexible care, regular contact, family engagement and usability of assistive devices. A general metamechanism that emerges concerns the synergy between an intervention strategy, the dementia trajectory and social and environmental factors, especially family involvement. A flexible service model for people with dementia and diabetes would enable this synergy in a way that would lead to the improved management of diabetes in people living with dementia.

LIMITATIONS

There is little evidence relating to the management of diabetes in people living with dementia, although including a wider literature provided opportunities for transferable learning. The outcomes in our CMOs are largely experiential rather than clinical. This reflects the evidence available. Outcomes such as increased engagement in self-management are potential surrogates for better clinical management of diabetes, but this is not proven.

CONCLUSIONS

This review suggests that there is a need to prioritise quality of life, independence and patient and carer priorities over a more biomedical, target-driven approach. Much current research, particularly that specific to people living with dementia and diabetes, identifies deficiencies in, and problems with, current systems. Although we have highlighted the need for personalised care, continuity and family-centred approaches, there is much evidence to suggest that this is not currently happening. Future research on the management of diabetes in older people with complex health needs, including those with dementia, needs to look at how organisational structures and workforce development can be better aligned to the needs of people living with dementia and diabetes.

Rethinking the assumptions of intervention research concerned with care at home for people with dementia

Aging populations have been positioned as a challenge to health and social service planning around the world, a situation even more pronounced in the case of persons with a diagnosis of dementia. While policy responses emphasize that care be provided for persons with dementia in home settings for as long as possible and that family carers be supported in the provision of this care, finding good ways to support families as they do the work of ‘delaying institutionalization’ has been challenging despite decades of intervention research intended to develop and evaluate interventions to support families. In this context of limited effectiveness it is useful to examine the assumptions informing research practices. Problematization is a method of literature analysis useful for clarifying and challenging assumptions informing a field of research in order to generate new approaches to research or new research questions. Our analysis suggests that although community-based intervention research has contributed significant knowledge about the kinds of things that might help families, there are limitations related to the dominant assumptions underlying the field. We highlight three areas for re-consideration: the overriding focus on caregiver–care recipient dyads, the under-determination of the object(s) of inquiry and the algorithmic nature of interventions themselves. Issues in these areas, we argue, arise from a commitment to homogeneity characteristic of biomedical models of disease that may need to be rethought in the face of consequential heterogeneity among research populations. That is, there is a mismatch between ‘dementia’ in the intervention research literature and ‘dementia’ in the life that is consequential for families living with these concerns.

Health economic evaluations of non-pharmacological interventions for persons with dementia and their informal caregivers: a systematic review

Background

This systematic review aims to review the literature on trial-based economic evaluations of non-pharmacological interventions directly targeted at persons with dementia as well as persons with mild cognitive impairment and their respective caregivers.

Methods

A systematic literature research was conducted for the timeframe from 2010 to 2016 in the following databases: Centre for Reviews and Dissemination, EconLit, Embase, Cochrane Library, PsycINFO and PubMed. Study quality was assessed according to the Drummond criteria.

Results

In total sixteen publications were identified. Health economic evaluations indicated the cost-effectiveness of physical exercise interventions and occupational therapy. There was also evidence to suggest that psychological and behavioral therapies are cost-effective. Health economic studies investigating psychosocial interventions mainly targeted towards informal caregivers showed inconsistent results.

Conclusions

Due to the increasing prevalence of dementia non-pharmacological interventions and their health economic impact are of increasing importance for health care decision-makers and HTA agencies.

Developing a dementia-specific preference--based quality of life measure (AD-5D) in Australia: a valuation study protocol

INTRODUCTION

Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer's Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer's Disease Five Dimensions (AD-5D) derived from the QOL-AD.

METHODS AND ANALYSIS

Discrete choice experiments with duration (DCE_TTO) and best-worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D.

ETHICS AND DISSEMINATION

The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences. This study has ethical approval.

What works for whom in the management of diabetes in people living with dementia: a realist review

BACKGROUND

Dementia and diabetes mellitus are common long-term conditions and co-exist in a large number of older people. People living with dementia (PLWD) may be less able to manage their diabetes, putting them at increased risk of complications such as hypoglycaemia. The aim of this review was to identify key mechanisms within different interventions that are likely to improve diabetes outcomes in PLWD.

METHODS

This is a realist review involving scoping of the literature and stakeholder interviews to develop theoretical explanations of how interventions might work, systematic searches of the evidence to test and develop the theories and their validation with a purposive sample of stakeholders. Twenty-six stakeholders - user/patient representatives, dementia care providers, clinicians specialising in diabetes or dementia and researchers - took part in interviews, and 24 participated in a consensus conference.

RESULTS

We included 89 papers. Ten focused on PLWD and diabetes, and the remainder related to people with either dementia, diabetes or other long-term conditions. We identified six context-mechanism-outcome configurations which provide an explanatory account of how interventions might work to improve the management of diabetes in PLWD. This includes embedding positive attitudes towards PLWD, person-centred approaches to care planning, developing skills to provide tailored and flexible care, regular contact, family engagement and usability of assistive devices. An overarching contingency emerged concerning the synergy between an intervention strategy, the dementia trajectory and social and environmental factors, especially family involvement.

CONCLUSIONS

Evidence highlighted the need for personalised care, continuity and family-centred approaches, although there was limited evidence that this happens routinely. This review suggests there is a need for a flexible service model that prioritises quality of life, independence and patient and carer priorities. Future research on the management of diabetes in older people with complex health needs, including those with dementia, needs to look at how organisational structures and workforce development can be better aligned to their needs.

Social capital interventions targeting older people and their impact on health: a systematic review

BACKGROUND

Observational studies show that social capital is a protective health factor. Therefore, we aim to assess the currently unclear health impact of social capital interventions targeting older adults.

METHODS

We conducted a systematic review based on a logic model. Studies published between January 1980 and July 2015 were retrieved from MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials and Web of Science. We included randomised controlled trials targeting participants over 60 years old and focused on social capital or its components (eg, social support and social participation). The comparison group should not promote social capital. We assessed risk of bias and impact on health outcomes and use of health-related resources applying a procedure from the Canadian Agency for Drugs and Technologies in Health (CADTH) based on vote-counting and standardised decision rules. The review protocol was registered in PROSPERO (reference number CRD42014015362).

RESULTS

We examined 17 341 abstracts and included 73 papers reporting 36 trials. Trials were clinically and methodologically diverse and reported positive effects in different contexts, populations and interventions across multiple subjective and objective measures. According to sufficiently reported outcomes, social capital interventions showed mixed effects on quality of life, well-being and self-perceived health and were generally ineffective on loneliness, mood and mortality. Eight trials with high quality showed favourable impacts on overall, mental and physical health, mortality and use of health-related resources.

CONCLUSIONS

Our review highlights the lack of evidence and the diversity among trials, while supporting the potential of social capital interventions to reach comprehensive health effects in older adults.
