Tailoring STrAtegies for RelaTives for Black and South Asian dementia family carers in the United Kingdom: A mixed methods study

North Macedonia interprofessional dementia care (NOMAD) - personalized care plans for people with dementia and caregiver psychoeducation delivered at home by interprofessional teams

Introduction

The increasing number of people living with dementia and its burden on families and systems particularly in low- and middle-income countries require comprehensive and efficient post-diagnostic management. This study aimed to explore the acceptability and efficacy of a multi-professional case management and psychoeducation model (North Macedonia Interprofessional Dementia Care, or NOMAD) delivered by mobile teams for people with dementia and their caregivers in North Macedonia.

Method

We conducted a two-arm randomized controlled trial comparing the intervention with treatment as usual. Participants were recruited from 12 general practitioner (GP) offices in the Skopje region. The NOMAD intervention included the delivery of a personalized care plan over four home visits to dyads of people with dementia and their caregivers by a team including a dementia nurse and a social worker, in collaboration with GPs and dementia experts, and the introduction of a caregiver manual. We assessed caregivers' depressive symptoms, burden, and quality of life and the neuropsychiatric symptoms, daily living activities, and service utilization of people with dementia at baseline and follow-up; we also assessed the acceptability of the intervention by analyzing case notes and attendance rates.

Results

One hundred and twenty dyads were recruited and randomized to either the control (n = 60) or the intervention group (n = 60). At follow-up, caregivers in the intervention group had, on average, scores that were 2.69 lower for depressive symptoms (95% CI [-4.75, -0.62], p = 0.012), and people with dementia had, on average, 11.32 fewer neuropsychiatric symptoms (95% CI [-19.74, -2.90], p = 0.009) and used, on average, 1.81 fewer healthcare services (95% CI [-2.61, -1.00], p < 0.001) compared to the control group. The completion of the home visits was 100%, but the intervention's acceptability was underpinned by relationship building, GP competencies, and resources to support families with dementia. There were no differences in the caregivers' quality of life and burden levels or daily living activities in people with dementia. NOMAD is the first case management, non-pharmacological, and multi-professional intervention tested in North Macedonia.

Discussion

The trial showed that it is effective in reducing caregivers' depressive symptoms and neuropsychiatric symptoms in people with dementia and the burden on health and social care services, and it is acceptable for families. Implementing NOMAD in practice will require building primary care capacity and recognizing dementia as a national priority.

Scaling-up an evidence-based intervention for family carers of people with dementia: Current and future costs and outcomes

OBJECTIVES

The STrAtegies for RelaTives (START) intervention is effective and cost-effective in supporting family carers of people with dementia. It is currently not available to all eligible carers in England. What would be the impacts on service costs and carer health-related quality of life if START was provided to all eligible carers in England, currently and in future?

METHODS

Effectiveness and cost-effectiveness data from a previously conducted randomised controlled trial were combined with current and future projections of numbers of people with newly diagnosed dementia to estimate overall and component costs and health-related quality of life outcomes between 2015 (base year for projections) and 2040.

RESULTS

Scaling-up START requires investments increasing annually but would lead to significant savings in health and social care costs. Family carers of people with dementia would experience improvements in mental health and quality of life, with clinical effects lasting at least 6 years. Scaling up the START intervention to eligible carers was estimated to cost £9.4 million in 2020, but these costs would lead to annual savings of £68 million, and total annual quality-adjusted life year (QALY) gains of 1247. Although the costs of START would increase to £19.8 million in 2040, savings would rise to £142.7 million and Quality adjusted life years gained to 1883.

CONCLUSIONS

Scaling-up START for family carers of people with dementia in England would improve the lives of family carers and reduce public sector costs. Family carers play a vital part in dementia care; evidence-based interventions that help them to maintain this role, such as START, should be available across the country.

Implementation and dissemination of home- and community-based interventions for informal caregivers of people living with dementia: a systematic scoping review

BACKGROUND

Informal caregivers of people with dementia (PwD) living at home are often the primary source of care, and, in their role, they often experience loss of quality of life. Implementation science knowledge is needed to optimize the real-world outcomes of evidence-based interventions (EBIs) for informal caregivers. This scoping review aims to systematically synthesize the literature that reports implementation strategies employed to deliver home- and community-based EBIs for informal caregivers of PwD, implementation outcomes, and the barriers and facilitators to implementation of these EBIs.

METHODS

Embase, MEDLINE, Web of Science, and Cochrane Library were searched from inception to March 2021; included studies focused on "implementation science," "home- and community-based interventions," and "informal caregivers of people with dementia." Titles and abstracts were screened using ASReview (an innovative AI-based tool for evidence reviews), and data extraction was guided by the ERIC taxonomy, the Implementation Outcome Framework, and the Consolidated Framework for Implementation Science Research; each framework was used to examine a unique element of implementation.

RESULTS

Sixty-seven studies were included in the review. Multicomponent (26.9%) and eHealth (22.3%) interventions were most commonly reported, and 31.3% of included studies were guided by an implementation science framework. Training and education-related strategies and provision of interactive assistance were the implementation strategy clusters of the ERIC taxonomy where most implementation strategies were reported across the reviewed studies. Acceptability (82.1%), penetration (77.6%), and appropriateness (73.1%) were the most frequently reported implementation outcomes. Design quality and packaging (intervention component suitability) and cosmopolitanism (partnerships) constructs, and patient's needs and resources and available resources (infrastructure) constructs as per the CFIR framework, reflected the most frequently reported barriers and facilitators to implementation.

CONCLUSION

Included studies focused largely on intervention outcomes rather than implementation outcomes and lacked detailed insights on inner and outer setting determinants of implementation success or failure. Recent publications suggest implementation science in dementia research is developing but remains in nascent stages, requiring future studies to apply implementation science knowledge to obtain more contextually relevant findings and to structurally examine the mechanisms through which implementation partners can strategically leverage existing resources and regional networks to streamline local implementation. Mapping local evidence ecosystems will facilitate structured implementation planning and support implementation-focused theory building.

Frameworks for cultural adaptation of psychosocial interventions: A systematic review with narrative synthesis

INTRODUCTION

Psychosocial dementia interventions may be less effective when used with populations for whom they were not initially intended. Cultural adaptation of interventions aims to increase effectiveness of interventions by enhancing cultural relevance. Use of theoretical frameworks may promote more systematic cultural adaptation. The aim of this review was to provide a comprehensive synthesis of published cultural adaptation frameworks for psychosocial interventions to understand important elements of cultural adaptation and guide framework selection.

METHOD

Five scientific databases, grey literature and reference lists were searched to January 2023 to identify cultural adaptation frameworks for psychosocial interventions. Papers were included that presented cultural adaptation frameworks for psychosocial interventions. Data were mapped to the framework for reporting adaptations and modifications to evidence-based interventions, then analysed using thematic synthesis.

RESULTS

Twelve cultural adaptation frameworks met inclusion criteria. They were mostly developed in the United States and for adaptation of psychological interventions. The main elements of cultural adaptation for psychosocial interventions were modifying intervention content, changing context (where, by whom an intervention is delivered) and consideration of fidelity to the original intervention. Most frameworks suggested that key intervention components must be retained to ensure fidelity, however guidance was not provided on how to identify or retain these key components. Engagement (ways to reach and involve recipients) and cultural competence of therapists were found to be important elements for cultural adaptation.

CONCLUSIONS

Comprehensive frameworks are available to guide cultural adaptation of psychosocial dementia interventions. More work is required to articulate how to ensure fidelity during adaptation, including how to identify and retain key intervention components.
