Assessing an evidence-based intervention for spouse caregivers of persons with Alzheimer's disease: results of a community implementation of the NYUCI in Israel

What works to support carers of older people and older carers? an international evidence map of interventions and outcomes

BACKGROUND

Unpaid carers of older people, and older unpaid carers, experience a range of adverse outcomes. Supporting carers should therefore be a public health priority. Our understanding of what works to support carers could be enhanced if future evaluations prioritise under-researched interventions and outcomes. To support this, we aimed to: map evidence about interventions to support carers, and the outcomes evaluated; and identify key gaps in current evidence.

METHODS

Evidence gap map review methods were used. Searches were carried out in three bibliographic databases for quantitative evaluations of carer interventions published in OECD high-income countries between 2013 and 2023. Interventions were eligible if they supported older carers (50 + years) of any aged recipient, or any aged carers of older people (50 + years).

FINDINGS

205 studies reported across 208 publications were included in the evidence map. The majority evaluated the impact of therapeutic and educational interventions on carer burden and carers' mental health. Some studies reported evidence about physical exercise interventions and befriending and peer support for carers, but these considered a limited range of outcomes. Few studies evaluated interventions that focused on delivering financial information and advice, pain management, and physical skills training for carers. Evaluations rarely considered the impact of interventions on carers' physical health, quality of life, and social and financial wellbeing. Very few studies considered whether interventions delivered equitable outcomes.

CONCLUSION

Evidence on what works best to support carers is extensive but limited in scope. A disproportionate focus on mental health and burden outcomes neglects other important areas where carers may need support. Given the impact of caring on carers' physical health, financial and social wellbeing, future research could evaluate interventions that aim to support these outcomes. Appraisal of whether interventions deliver equitable outcomes across diverse carer populations is critical.

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.

Development and evaluation of an intervention on suPpoRting infOrmal cAregivers of older people with early CogniTIVe declinE (PROACTIVE): a study protocol based on the Medical Research Council framework

INTRODUCTION

Caring for people with cognitive problems can have an impact on informal caregivers' health and well-being, and especially increases pressure on healthcare systems due to an increasing ageing society. In response to a higher demand of informal care, evidence suggests that timely support for informal caregivers is essential. The New York University Caregiver Intervention (NYUCI) has proven consistent effectiveness and high adaptability over 30 years. This study has three main objectives: to develop and evaluate the Flemish adaptation of the NYUCI in the context of caregiving for older people with early cognitive decline; to explore the causal mechanism of changes in caregivers' health and well-being and to evaluate the validity and feasibility of the interRAI Family Carer Needs Assessment in Flanders.

METHODS AND ANALYSIS

Guided by Medical Research Council framework, this study covers the development and evaluation phases of the adapted NYUCI, named PROACTIVE-suPpoRting infOrmal cAregivers of older people with early CogniTIVe declinE. In the development phase, we will identify the evidence base and prominent theory, and develop the PROACTIVE intervention in the Flemish context. In the evaluation phase, we will evaluate the PROACTIVE intervention with a pretest and posttest design in 1 year. Quantitative data will be collected with the BelRAI Screener, the BelRAI Social Supplement and the interRAI Family Carer Needs Assessment at baseline and follow-up points (at 4, 8 and 12 months). Qualitative data will be collected using counselling logs, evaluation forms and focus groups. Quantitative data and qualitative data will be analysed with SAS 9.4 software and NVivo software, respectively. Efficacy and process evaluation of the intervention will be performed.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of KU Leuven with a dossier number G-2020-1771-R2(MAR). Findings will be disseminated through community information sessions, peer-reviewed publications and national and international conference presentations.
