Recruitment and methodological issues in conducting dementia research in British ethnic minorities: A qualitative systematic review

Understanding dementia in minority ethnic communities: The perspectives of key stakeholders interviewed as part of the IDEAL programme

Future populations of older adults in the UK, those aged 65+, will demonstrate increased diversity in terms of their ethnic identity resultant from the ageing of the post-war migrants from India, Pakistan, Bangladesh, and the Caribbean. As a consequence, there will be an increase in the numbers of older adults from these communities living with age-related chronic diseases such as dementia. In response to these demographic changes, we need to develop a research, policy and practice agenda that is inclusive and provides evidence for the development of culturally diverse and effective models of service delivery. This requires engagement with three key stakeholder groups: (a) people with dementia; (b) their carers; and (c) the wider community. As part of the IDEAL research programme on living well with dementia, we undertook semi-structured interviews with twelve community leaders, defined as known and trusted individuals active in their respective communities, and six community members (two people living with dementia and four carers). We explored their understandings, experiences, and views of about dementia. Our analysis identified two overarching themes. The migrant lifecourse highlighted issues of not belonging, discrimination and racism. This framed our second theme, the cultural context of dementia, which addressed dementia knowledge and attitudes, service provision and service access, and how being part of a minority ethnic community made a difference to these experiences. Our study highlights how lifecourse experiences of negative hostile social and policy environments and services can be profound and long-lasting and provide a prism through which accessing dementia care is experienced. Our findings argue for the inclusion of diverse views and lifecourse experiences within the context of developing a dementia strategy for research, policy and practice that is appropriate for a multicultural and heterogenous society.

Living Alone With Mild-to-Moderate Dementia Over a Two-Year Period: Longitudinal Findings From the IDEAL Cohort

OBJECTIVES

To compare the experiences of people with dementia living alone or with others and how these may change over two years.

DESIGN

We analysed longitudinal data from three assessment waves, one year apart, in the British IDEAL cohort.

SETTING

Participants with mild-to-moderate dementia were recruited through National Health Service providers, where possible with a family caregiver, and interviewed at home.

PARTICIPANTS

The current analyses include 281 people with dementia living alone and 1,244 living with others at baseline; follow-up data were available for 200 and 965 respectively at time 2 and 144 and 696 respectively at time 3. For those living alone, 140 nonresident caregivers contributed at baseline, 102 at time 2 and 81 at time 3. For those living with others, 1,127 family caregivers contributed at baseline, 876 at time 2 and 670 at time 3.

MEASUREMENTS

Assessments covered: cognitive and functional ability; self-reported perceptions of health, mood, social engagement, quality of life, satisfaction with life and well-being; use of in-home and community care; and transitions into residential care.

RESULTS

People living alone tended to have better cognitive and functional ability and were more frequent users of in-home care. However, they experienced poorer physical, social, and psychological health and reduced quality of life, satisfaction with life, and well-being. These differences persisted over time and rates of transition into residential care were higher.

CONCLUSIONS

To facilitate continuing in place for people with dementia living alone, a dual focus on supporting functional ability and addressing psychosocial needs is essential in the context of an enabling policy framework.

Effective interventions to increase representation of under-served groups in randomised trials in UK and Ireland: a scoping literature review

Background

Participants in clinical trials often do not reflect the populations that could benefit from the treatments being investigated. There are known barriers to trial participation for under-served groups, but limited evidence on strategies to alleviate these barriers to improve representation. This scoping review aimed to identify effective interventions and design features that improve the representation `of under-served groups in trials, focusing on the UK and Ireland.

Methods

We included methodological research studies that reported interventions to improve representation of ethnic minority groups, socioeconomically disadvantaged groups, older people, or those with impaired capacity to consent to randomised controlled trials, conducted in the UK and Ireland, published between 2000-2021. Systematic searches were conducted in November 2021 and data were independently extracted by two authors and narratively synthesised.

Results

Seven studies were included: one randomised controlled study embedded in five trials, one mixed-methods study, and five studies reporting 'lessons learnt' from one trial. We categorised the 47 reported interventions or strategies into nine broad themes: Recruitment sites, recruitment settings, community engagement, and communication with participants, incentives, inclusion criteria, flexibility, patient documentation, and the consent process. Only 28/47 interventions were evaluated, 23 of which were comparison of recruitment pathways.The randomised study found that a £100 incentive mentioned in the invitation letter increased positive responses overall across drug trials in cardiovascular disease and hypertension, but not for older people or those living in the most deprived areas. Invitation letters via GPs and working with communities were reported as successful recruitment pathways in recruiting different under-served populations.

Conclusions

Interventions aiming to improve the recruitment of under-served groups in the UK and Ireland were reported across seven papers, but their effectiveness was rarely rigorously evaluated. Included studies were context specific. Using a variety of recruitment methods is likely to help achieve a more diverse cohort.

Recruiting Persons With Dementia: A Systematic Review of Facilitators, Barriers, and Strategies

Study recruitment of persons with dementia is challenging. We aimed to assess facilitators, barriers, and strategies to identify and approach persons with dementia for recruitment to dementia care studies. We systematically searched MEDLINE/PubMed, CINAHL, Web of Science, and other sources (ORRCA [Online Resource for Research in Clinical triAls]; pertinent evidence syntheses; citation searching) and narratively summarised the results (PROSPERO CRD42022342600). Facilitators and barriers consisted of "characteristics of participants, researchers, clinical contact persons", "study characteristics", and "communication with participants". The highest number of participants were recruited by study information in electronic and print formats, as well as by networking and collaboration. Advertisements proved to be the most expensive way of recruitment. There is limited evidence on the impact of recruitment strategies to identify persons with dementia for recruitment to dementia care studies. Our analysis of facilitators and barriers may inform research teams in designing strategies to identify persons with dementia for recruitment purposes.

Volume, scope, and consideration of ethical issues in Indigenous cognitive impairment and dementia research: A systematic scoping review of studies published between 2000-2021

INTRODUCTION

High quality research involving Indigenous people with cognitive impairment and dementia is critical for informing evidence-based policy and practice. We examined the volume, scope and ethical considerations of research related to dementia with Indigenous populations globally from January 2000-December 2021.

METHODS

Studies were included if they were published in English from 2000 to 2021 and provided original data that focused on cognitive impairment or dementia in any Indigenous population.

RESULTS

The search yielded 13,009 papers of which, 76 met inclusion criteria. The overall number of papers increased over time. Studies were mostly conducted in Australia with Aboriginal and Torres Strait Islander people (n = 30; 39%). Twenty-six papers directly involved Indigenous participants with cognitive impairment or dementia. Of these studies, ethics approval was commonly required from two or more committees (n = 23, 88.5%). Ethical and legal governance frameworks were rarely discussed.

DISCUSSION

There is a clear need for further robust studies examining cognitive impairment and dementia with Indigenous populations. Future research should consider the ethical aspects of involving Indigenous participants with cognitive impairment in research.

Rapid development of a COVID-19 care planning decision-aid for family carers of people living with dementia

INTRODUCTION

COVID-19 has disproportionately affected people living with dementia and their carers. Its effects on health and social care systems necessitated a rapid-response approach to care planning and decision-making in this population, with reflexivity and responsiveness to changing individual and system needs at its core. Considering this, a decision-aid to help families of persons with dementia was developed.

OBJECTIVES

To coproduce with people living with dementia, and the people who care for them, a decision-aid for family carers of people living with dementia, to support decisions during the COVID-19 pandemic and beyond.

METHODS

Semi-structured interviews were undertaken in 2020 with: (1) staff from two English national end-of-life and supportive care organizations; and (2) people living with dementia and family carers. Simultaneously, a rapid review of current evidence on making decisions with older people at the end of life was undertaken. Evidence from these inputs was combined to shape the decision-aid through a series of workshops with key stakeholders, including our patient and public involvement group, which consisted of a person living with dementia and family carers; a group of clinical and academic experts and a group of policy and charity leads.

RESULTS

The rapid review of existing evidence highlighted the need to consider both process and outcome elements of decision-making and their effects on people living with dementia and their families. The qualitative interviews discussed a wide range of topics, including trust, agency and confusion in making decisions in the context of COVID-19. The decision-aid primarily focussed on care moves, legal matters, carer wellbeing and help-seeking.

CONCLUSIONS

Combining different sources and forms of evidence was a robust and systematic process that proved efficient and valuable in creating a novel decision-aid for family carers within the context of COVID-19. The output from this process is an evidence-based practical decision-aid coproduced with people living with dementia, family carers, clinical and academic experts and leading national dementia and palliative care organizations.

PATIENT OR PUBLIC CONTRIBUTION

We worked with people living with dementia and family carers and other key stakeholders throughout this study, from study development and design to inclusion in stakeholder workshops and dissemination.

A framework for preferred practices in conducting culturally competent health research in a multicultural society

Background

Improving the health and well-being of the whole population requires that health inequities be addressed. In an era of unprecedented international migration, meeting the health care needs of growing multicultural or multiethnic societies presents major challenges for health care systems and for health researchers. Considerable literature exists on the methodological and ethical difficulties of conducting research in a cross-cultural context; however, there is a need for a framework to guide health research in multicultural societies.

Methods

The framework was informed by “research on research” that we have undertaken in community and primary health care settings in Sydney, Australia. Case studies are presented as illustrative examples.

Results

We present a framework for preferred practices in conducting health research that is culturally informed, high-quality, safe, and actionable.

Conclusions

The framework is not intended to be universal, however many of its aspects will have relevance for health research generally. Application of the framework for preferred practices could potentially make health research more culturally competent, thus enabling enhanced policies, programmes and practices to better meet population health needs. The framework needs to be further tested and refined in different contexts.

Recruitment and methodological issues in conducting dementia research in British ethnic minorities: A qualitative systematic review

OBJECTIVE

Identifying existing recruitment and methodological issues within dementia research conducted in UK studies that included ethnic minorities.

METHODS

We searched for and included any publication detailing dementia research in the UK that included any ethnic minority. The search results and all titles and abstracts were screened according to the inclusion criteria followed by screening of the full texts. We extracted data regarding the recruitment and methodological issues faced by the researchers. This data was combined and listed, and related issues were grouped into overarching themes and subthemes.

RESULTS

Of 52 publications suitable for analysis, 33 provided data collated into six themes: attitudes and beliefs about dementia in ethnic minority communities, recruitment process, data collection issues, practical issues, researcher characteristics, and lack of published research and normative data. These themes allowed us to identify three areas responsible for addressing these recruitment and methodological issues: community and patient education, health services, and researchers' training.

CONCLUSIONS

This is the first review identifying recruitment and methodological issues within UK dementia research that included ethnic minorities. We now have a compilation of reported existing issues and a framework of areas responsible for addressing them and devising solutions.
