BrainWorks: A Comparative Effectiveness Trial to Examine Alzheimer's Disease Education for Community-Dwelling African Americans

Use of Community-Engaged Research Approaches in Clinical Interventions for Neurologic Disorders in the United States: A Scoping Review and Future Directions for Improving Health Equity Research

BACKGROUND AND OBJECTIVES

Evidence suggests a significant prevalence of race and ethnic disparities in the United States among people with neurologic conditions including stroke, Alzheimer disease and related dementia (ADRD), Parkinson disease (PD), epilepsy, spinal cord injury (SCI), and traumatic brain injury (TBI). Recent neurologic research has begun the paradigm shift from observational health disparities research to intervention research in an effort to narrow the disparities gap. There is an evidence base that suggests that community engagement is a necessary component of health equity. While the increase in disparities focused neurologic interventions is encouraging, it remains unclear whether and how community-engaged practices are integrated into intervention design and implementation. The purpose of this scoping review was to identify and synthesize intervention studies that have actively engaged with the community in the design and implementation of interventions to reduce disparities in neurologic conditions and to describe the common community engagement processes used.

METHODS

Two databases, PubMed and CINAHL, were searched to identify eligible empirical studies within the United States whose focus was on neurologic interventions addressing disparities and using community engagement practices.

RESULTS

We identified 392 disparity-focused interventions in stroke, ADRD, PD, epilepsy, SCI, and TBI, of which 53 studies incorporated community engagement practices: 32 stroke studies, 15 ADRD, 2 epilepsy studies, 2 PD studies, 1 SCI study, and 1 TBI study. Most of the interventions were designed as randomized controlled trials and were programmatic in nature. The interventions used a variety of community engagement practices: community partners (42%), culturally tailored materials and mobile health (40%), community health workers (32%), faith-based organizations and local businesses (28%), focus groups/health need assessments (25%), community advisory boards (19%), personnel recruited from the community/champions (19%), and caregiver/social support (15%).

DISCUSSION

Our scoping review reports that the proportion of neurologic intervention studies incorporating community engagement practices is limited and that the practices used within those studies are varied. The major practices used included collaboration with community partners and utilization of culturally tailored materials. We also found inconsistent reporting and dissemination of results from studies that implemented community engagement measures in their interventions. Future directions include involving the community in research early and continuously, building curricula that address challenges to community engagement, prioritizing the inclusion of community engagement reporting in peer-reviewed journals, and prioritizing and incentivizing research of subpopulations that experience disparities in neurologic conditions.

Testing an Alzheimer's Disease Educational Approach in Two African American Neighborhoods in Florida

African Americans experience a significantly greater burden of Alzheimer's disease (AD) compared to non-Hispanic White Americans. Raising awareness and increasing knowledge of AD within African American communities is an important step towards addressing these disparities. The purpose of this study was to assess the effectiveness of two approaches to sharing AD knowledge with community residents. Using a quasi-experimental design, African American participants were recruited through community partners and local resources in two comparable neighborhoods in Duval County, Florida, which formed the intervention and the comparison groups for this study. The identical 40-min educational lecture was provided to both groups. In the intervention community, the lecture was followed by focus group sessions modeled after the Dementia Friendly America toolkit. In the comparison community, the lecture was followed by a social event where participants could interact informally with the speaker and dementia outreach staff. A brief quantitative survey assessing AD knowledge was administered to participants in both groups before the education session, immediately after the lecture, and 2 months later. Results indicate that both groups improved their knowledge scores at immediate post-test. Scores for both groups declined at 2-month follow-up, but the comparison group's scores declined more precipitously than the intervention group's scores (p = 0.0.21). These results suggest that conducting focus groups and interviews following a lecture on AD may help better retain AD knowledge over time.

A Text Messaging Intervention to Support Latinx Family Caregivers of Individuals With Dementia (CuidaTEXT): Development and Usability Study

BACKGROUND

Latinx family caregivers of individuals with dementia face many barriers to caregiver support access. Interventions to alleviate these barriers are urgently needed.

OBJECTIVE

This study aimed to describe the development of CuidaTEXT, a tailored SMS text messaging intervention to support Latinx family caregivers of individuals with dementia.

METHODS

CuidaTEXT is informed by the stress process framework and social cognitive theory. We developed and refined CuidaTEXT using a mixed methods approach that included thematic analysis and descriptive statistics. We followed 6 user-centered design stages, namely, the selection of design principles, software vendor collaboration, evidence-based foundation, caregiver and research and clinical advisory board guidance, sketching and prototyping, and usability testing of the prototype of CuidaTEXT among 5 Latinx caregivers.

RESULTS

CuidaTEXT is a bilingual 6-month-long SMS text messaging-based intervention tailored to caregiver needs that includes 1-3 daily automatic messages (n=244) about logistics, dementia education, self-care, social support, end of life, care of the person with dementia, behavioral symptoms, and problem-solving strategies; 783 keyword-driven text messages for further help with the aforementioned topics; live chat interaction with a coach for further help; and a 19-page reference booklet summarizing the purpose and functions of the intervention. The 5 Latinx caregivers who used the prototype of CuidaTEXT scored an average of 97 out of 100 on the System Usability Scale.

CONCLUSIONS

CuidaTEXT's prototype demonstrated high usability among Latinx caregivers. CuidaTEXT's feasibility is ready to be tested.

Impact of dementia literacy interventions for non-health-professionals: systematic review and meta-analysis

OBJECTIVES

To assess evidence regarding the effects of interventions aimed at improving dementia literacy for different groups of non-health-professionals.

METHODS

A systematic search for relevant interventions was conducted using a range of online databases (e.g. CINAHL, Embase, Medline, ProQuest, and PsycINFO) and hand-searching of reference lists. Eligible interventions were identified based on predefined inclusion/exclusion criteria and methodological quality criteria. Meta analyses were performed using a random-effects model.

RESULTS

The final review included 14 interventions, which were either randomised controlled trials or non-randomised controlled trials. The interventions had varied contents, approaches, settings, and outcome measures. Evidence of improved dementia literacy in various aspects was found, and the intervention effects were strongest on knowledge of dementia.

DISCUSSION

There is evidence for the positive impact of dementia literacy interventions on different groups of non-health-professionals. Best practices in intervention contents, approaches, and outcome measures should be examined to guide future interventions.

Interventions to promote dementia knowledge among racial/ethnic minority groups: A systematic review

BACKGROUND

Certain racial/ethnic minority groups have a higher risk of developing dementia, yet studies have demonstrated that they often have limited knowledge and understanding of this disease. An increasing number of educational and advocacy programs have been developed to promote dementia knowledge. We aimed at assessing current evidence and quality regarding educational interventions for promoting dementia knowledge.

METHODS

We searched for intervention studies published in English that focused on educational interventions for promoting dementia knowledge among racial/ethnic minority groups. We identified 25 relevant studies through PubMed, PsycINFO, CINAHL, and Scopus, using tailored search terms. We screened titles and abstracts, reviewed full texts, synthesized relevant evidence, and evaluated the studies' quality based on the Mixed Methods Appraisal Tool. Relevant intervention studies took place in communities, hospitals or clinics, and schools, and online.

RESULTS

Most studies were conducted in the United States (n = 21), followed by the UK (n = 3). Over half of the studies included Asian/Pacific Islander groups (n = 14), followed by Black groups (n = 12) and Hispanic groups (n = 11). The intervention delivery mode varied across studies-from workshops hosted in a faith community to talk shows on YouTube. Target populations included middle-aged and older adults, caregivers and family members, health students and professionals, and elementary school students. Common content included symptoms and signs of dementia, protective and risk factors, and local resources. The assessment of study outcomes varied across studies. Improvement in dementia knowledge and attitudes towards dementia was reported in many studies. Among the included studies, intervention satisfaction was high. The overall quality of the interventions was low.

CONCLUSION

Formally evaluated educational interventions promoting dementia knowledge are at an early stage. Existing published interventions showed adequate acceptability and promise in promoting better understanding and awareness of dementia in minority groups. More well-designed randomized controlled trials are needed.

Public knowledge of the influence of modifiable cardiovascular risk factors on dementia: a systematic literature review and meta-analysis

OBJECTIVES

This systematic review examined whether the general public are aware of the influence of modifiable cardiovascular risk factors (CVRFs) on dementia.

METHODS

Following PRISMA guidelines, five electronic databases (PubMed, Medline, CINAHL, ProQuest, and Scopus) were searched for studies published from 2009-2019, using the key terms "knowledge," "modifiable cardiovascular risk factors," and "dementia." Standardized critical appraisal instruments were used to evaluate the quality of the studies.

RESULTS

Of the 1,533 articles that were screened, 26 were included in this review. Modifiable CVRFs of dementia included behavioral factors (physical inactivity, poor dietary practices, high alcohol consumption, and heavy smoking) and medical conditions (hypertension, diabetes mellitus, hypercholesterolemia, and obesity). Although the association between CVRFs and dementia was identified (pooled prevalence is 24-50%), overall knowledge about this relationship in the general public was low. Sociodemographic variables, such as higher education, better economic status, and prior contact with a person with dementia, positively influenced dementia risk knowledge. Ethnic minorities showed good awareness of dementia risk from cardiovascular-related conditions.

CONCLUSION

Despite dementia is considered as a public health priority by World Health Organization, knowledge of the modifiable CVRFs and dementia is low in the general population. Public health policymakers should develop appropriate educational programs and interventions to equip the communities and vulnerable groups with this understanding so that they can be prepared to reduce dementia risk.

Promoting dementia awareness in African-American faith communities

INTRODUCTION

Alzheimer's disease and other dementia-related disorders are affecting the African-American community at alarming rates. African-American churches have traditionally been places of refuge where families go for support. However, many churches lack programs or resources to support families affected by dementia. In response, a nurse-led interdisciplinary collaborative partnered with churches to promote dementia awareness through education.

PURPOSE

The purpose of this analysis was to (a) describe the demographics of those seeking dementia education in African-American faith communities; (b) identify prior knowledge of dementia community resources; and (c) determine the preliminary usefulness of the education provided.

METHODS

Over the course of 16 months, 202 individuals attended nine educational sessions hosted by five churches across metropolitan Atlanta. Quantitative surveys were used to collect demographics and evaluate the educational sessions.

RESULTS

The majority of attendees were African-American adults (91%), women (75%), and unaware of dementia resources (66%). Several attendees identified themselves as church leaders, community/church members, caregivers, and/or healthcare professionals. Attendees expressed the educational content was applicable to themselves or their families.

CONCLUSION

Results help identify ways to alter and/or strengthen the educational content and serve as a guide for developing culturally relevant, faith-based community programs.

Recruitment into the Alzheimer Prevention Trials (APT) Webstudy for a Trial-Ready Cohort for Preclinical and Prodromal Alzheimer's Disease (TRC-PAD)

BACKGROUND:

The Alzheimer Prevention Trials (APT) Webstudy is the first stage in establishing a Trial-ready Cohort for Preclinical and Prodromal Alzheimer’s disease (TRC-PAD). This paper describes recruitment approaches for the APT Webstudy.

OBJECTIVES:

To remotely enroll a cohort of individuals into a web-based longitudinal observational study. Participants are followed quarterly with brief cognitive and functional assessments, and referred to Sites for in-clinic testing and biomarker confirmation prior to enrolling in the Trial-ready Cohort (TRC).

DESIGN:

Participants are referred to the APT Webstudy from existing registries of individuals interested in brain health and Alzheimer’s disease research, as well as through central and site recruitment efforts. The study team utilizes Urchin Tracking Modules (UTM) codes to better understand the impact of electronic recruitment methods.

SETTING:

A remotely enrolled online study.

PARTICIPANTS:

Volunteers who are at least 50 years old and interested in Alzheimer’s research.

MEASUREMENTS:

Demographics and recruitment source of participant where measured by UTM.

RESULTS:

30,650 participants consented to the APT Webstudy as of April 2020, with 69.7% resulting from referrals from online registries. Emails sent by the registry to participants were the most effective means of recruitment. Participants are distributed across the US, and the demographics of the APT Webstudy reflect the referral registries, with 73.1% female, 85.0% highly educated, and 92.5% Caucasian.

CONCLUSIONS:

We have demonstrated the feasibility of enrolling a remote web-based study utilizing existing registries as a primary referral source. The next priority of the study team is to engage in recruitment initiatives that will improve the diversity of the cohort, towards the goal of clinical trials that better represent the US population.

Mental Health Issues in Racial and Ethnic Minority Elderly

PURPOSE OF REVIEW

With the current demographic shifts, the USA will soon become a "majority minority" country. While the population of the USA over the age of 65 years is projected to increase from 13.5% to 20% in 2030, racial and ethnic minority elderly, who are now 21% of the population, will increase to 44% by 2060. As the population of racial and ethnic minority elderly continues to grow, there is a demographic and public health imperative to understand how to better care for this population.

RECENT FINDINGS

This review evaluates the impact of race, ethnicity, and culture on the aging process, psychopathology, psychiatric care, psychiatric education, and clinical research. Relevant advances in recent literature are reviewed, and gaps in cultural competency education and training, and clinical research are identified. Clinical recommendations and future directions are highlighted, as an effort to improve care for this underserved population at risk. By striving to better care for racial and ethnic minority elders, one of the most marginalized populations, health care is improved for all.
