Community-Based Participatory Research (CBPR) to Enhance Participation of Racial/Ethnic Minorities in Clinical Trials: A 10-Year Systematic Review.

Abstract: There has not been a significant improvement in the rate of clinical trial accrual in more than 20 years. Worse, the challenge of inadequate representation among racial and ethnic minorities also persists, deepening disparities in health. Community-Based Participatory Research (CBPR) is a participatory communication method that centers on effective dialogue between researchers and community stakeholders with the goal of creating an equitable partnership for health and social change. The objective of the current study was to provide an update since a systematic review in 2012, on the current status of the empirical research, with a particular focus on the elements of CBPR methods used to improve the rate of accrual of members of racial and ethnic minority communities for clinical trials. Our systematic review found a large increase in the number of CBPR related studies and studies related to racial and ethnic representation in research. More than 85% of studies employing CBPR methods saw statistically positive outcomes. Specifically, the elements of CBPR that are associated with these positive outcomes include community partner participation in (1) a study advisory committee, (2) data collection, (3) the development of interventions, and (4) participant recruitment. However, the results of our study indicate that researchers need to be more transparent about the extent of community participation as well as more thoroughly and accurately describe the nature of the partnership with members of minority communities in order to build upon the scientific literature on community-engaged methods.

Exploring Willingness to Participate in Clinical Trials by Ethnicity

Abstract: African-Americans and Hispanic-Americans are disproportionately affected by cancer, yet underrepresented in cancer clinical trials. Because of this, it is important to understand how attitudes and beliefs about clinical trials vary by ethnicity. A national, random sample of 860 adults was given an online survey about attitudes toward clinical trials. We examined willingness to participate in clinical trials, attitudes toward clinical trials, trust in doctors, attitudes toward alternative and complementary medicine, and preferred information channels. Results indicate that African-American and Hispanic-American participants have more negative attitudes about clinical trials, more distrust toward doctors, more interest in complementary and alternative medicine, and less willingness to participate in clinical trials than white/non-Hispanics, although specific factors affecting willingness to participate vary. The channels people turn to for information on clinical trials also varied by ethnicity. These results help explain the ethnic disparities in cancer clinical trial enrollment by highlighting some potential underlying causes and drawing attention to areas of importance to these groups.

Factors associated with biomedical research participation within community-based samples across 3 National Cancer Institute-designated cancer centers.

Abstract: Background Engaging diverse populations in biomedical research, including biospecimen donation, remains a national challenge. This study examined factors associated with an invitation to participate in biomedical research, intent to participate in biomedical research in the future, and participation in biomedical research and biospecimen donation among a diverse, multilingual, community-based sample across 3 distinct geographic areas. Methods Three National Cancer Institute-designated cancer centers engaged in community partnerships to develop and implement population health assessments, reaching a convenience sample of 4343 participants spanning their respective catchment areas. Data harmonization, multiple imputation, and multivariable logistic modeling were used. Results African Americans, Hispanic/Latinos, and other racial minority groups were more likely to be offered opportunities to participate in biomedical research compared to whites. Access to care, history of cancer, educational level, survey language, nativity, and rural residence also influenced opportunity, intent, and actual participation in biomedical research. Conclusions Traditionally underserved racial and ethnic groups reported heightened opportunity and interest in participating in biomedical research. Well-established community partnerships and long-standing community engagement around biomedical research led to a diverse sample being reached at each site and may in part explain the current study findings. However, this study illustrates an ongoing need to establish trust and diversify biomedical research participation through innovative and tailored approaches. National Cancer Institute-designated cancer centers have the potential to increase opportunities for diverse participation in biomedical research through community partnerships and engagement. Additional work remains to identify and address system-level and individual-level barriers to participation in both clinical trials and biospecimen donation for research.

Culturally tailored interventions for ethnic minorities: A scoping review.

Abstract: Aim This scoping review identifies strengths and weakness of culturally tailored interventions for ethnic minorities' care in the United States. It reviews recently published studies to improve understanding of these interventions for future research and practice. Design Scoping review. Methods By searching five electronic databases-CINAHL, PubMed, Ovid, Scopus and Web of Science, this review located 58 empirical studies published between 2015-2019. This review was guided by the PRISMA statements. Results The review identified four weaknesses and five strengths of culturally tailored interventions. Weaknesses included unclear guidelines, low attention and retention rates, failure to measure processes and inadequate training for healthcare providers. The intervention strengths were culturally respectful and patient-centred care, healthy lifestyle promotion, increased family and community supports, technology use for efficient and timely care and increased knowledge of disease by participants.

Trust in national health information sources in the United States: comparing predictors and levels of trust across three health domains.

Abstract: Public trust in traditional sources of health information is essential for public health agencies and organizations to perform necessary public health functions. Little research has examined levels and predictors of trust in government health agencies and national health organizations. Additionally, few studies have simultaneously analyzed trust in multiple health topics. The major aim of this study was to compare levels and factors associated with trust in national health sources across three health topics: information about tobacco, electronic cigarettes, and general health. Data from two cycles of the National Cancer Institute's Health Information National Trends Survey collected in 2015 and 2017 were merged and analyzed for this study (n = 5,474). A series of weighted multivariable logistic regression models calculated odds of high trust in government health agencies and health organizations for each health topic. More respondents reported high trust in health organizations than for government health agencies across all topics. More participants reported high trust in these sources tobacco information, as compared to general health or e-cigarette information. Logistic models found that those higher in information seeking confidence were more likely to report high trust across all models. Other demographic variables were inconsistent predictors of trust across topics. This study highlights inconsistent sociodemographic predictors of trust across multiple health topics and national health sources. Researchers, practitioners, and policymakers should consider the unique context of specific health topics in health promotion campaigns, partner with existing community-based organizations, and encourage and enable health information seeking.
