Abstract

There is a widespread recognition that health disparities impact Hispanics collectively; however, much less is known about the disease risk and outcomes with respect to the heterogeneity of Hispanic subgroups. Community-engaged approaches and strategies to research are essential for reaching these at-risk populations and building trust among community and research partners who serve and care for Hispanics. These methods are not only useful for engaging diverse populations but also useful in elucidating and differentiating nuances within and among Hispanic subgroup characteristics and their perspectives regarding participation in biomedical research. There is a growing body of evidence supporting the use of participatory research methods in studying, developing, and implementing culturally sensitive cancer prevention interventions and strategies among diverse racial/ethnic minority populations. Much of the previous work in this area has addressed program adaptation or cultural tailoring of existing cancer educational programs and materials. However, the adoption of community engaged research approaches in translational or transdisciplinary research are less understood and may have the potential to improve inclusion and representation of Hispanics in biomedical research studies and to shed light on how to create conditions for health and health equity. This chapter describes novel applications of community-based approaches to biobanking and biospecimen research areas to highlight (1) three critical steps for engaging Hispanic communities in cancer research, (2) best practices and scientifically based strategies and considerations for enhancing community engagement in research, and (3) lessons learned.

Introduction

The disproportionately lower number of certain subpopulations participating in clinical and prevention research has a significant impact on the representativeness of scientific outcomes and results in social and clinical injustices [1]. A sequential set of community-based studies were conducted to engage diverse medically underserved populations in biospecimen donation for cancer genomic research [2, 3]. This chapter is organized around three critical steps of community engagement that are relevant to participatory research as applied to novel and formative efforts focused on biospecimen science that were used in the Hoy y Mañana (translated to Today and Tomorrow) study. Specifically, these studies developed and tested community-based interventions to identify influential factors regarding participation in biospecimen donation to a biorepository at a cancer center in upstate New York for future cancer research from a Northeast Hispanic, predominantly Puerto Rican population [4].

Three Critical Steps for Engaging Hispanics in Cancer Research

Community engagement is an essential component to reaching and including diverse and\or hard-to-reach populations in biomedical research with a focus on reducing health disparities and improving individual health. There are three overarching steps that can be applied when working at the community level that facilitate engaged approaches to research and enhance the relevance of research as an opportunity to build capacity and increase health equity. The following steps are not exclusive to biospecimen research studies but can be applied to a variety of public health issues and research topics targeting efforts at a community level.

Step 1: Know the Community

The first step is to know the community. Knowing the community requires an in-depth understanding of community members and stakeholders, barriers and assets, population demographics, and community context. The Community Development Model for Public Health Applications is a comprehensive model that integrates the factors essential to knowing a community as the primary unit of analysis and can be used as a framework to guide community-engaged research efforts [5]. Additionally, Community-Based Participatory Research (CBPR) principles and methods also serve as a foundation for collaborative approaches to research that enhance and support community engagement research activities across a variety of topics and disciplines.

Involving the community at the earliest stages of the research process can better ensure acceptability and relevance to the population of interest. The Hoy y Mañana (HyM) study focused on the opportunity to build capacity with preexisting community partners around the topic of biospecimen donation for future cancer research [3]. Capacity building is a key component of the CBPR principles that values skill building and co-learning [6]. Community partners played an integral role in linking the pilot research project to the community and vice versa. Transparent and consistent communication was an important factor throughout the process and contributed to an effective partnership process in engaging the community and assessing feasibility to conduct community-based cancer research involving the collection of biospecimens.

Formative research including structured in-person interviews and focus groups were completed with Hispanic community leaders, staff from the biorepository at the cancer center, and Hispanic participants from the community. Table 20.1 provides examples of the qualitative methods employed in the HyM study to illustrate the process used to gain the community perspective regarding biospecimen donation for cancer research and how the data informed each step of the research. The key informant interviews with Hispanic community leaders were part of the first level of community data collection. These individuals are best described as community leaders (e.g., pastors, civic leaders, and clinicians who practice in the community). They are trusted individuals who often assume an informal gatekeeper role in the community because of their established relationships with members of the community at large. Knowledge of the community facilitates an understanding of who these respected and trusted leaders are and the potential impact they can have in linking the community to collaborative research opportunities. Rodriguez et al. describe the methods and community-engaged research process in detail as well as the resultant findings from a predominantly Puerto Rican population with regard to their self-reported awareness and interest in biospecimen donation for cancer research [3].

Step 2: Know the Goal of Engagement Activities

Community-engaged research efforts often require understanding and commitment to an iterative process; however, the goal of engagement activities should be transparent and mutually agreed upon prior to research implementation to ensure acceptance and commitment to the process. In the HyM study, the objective of this first step was to better understand the community’s awareness, knowledge, attitudes, and interest in biospecimen donation for cancer research. The results from the formative research were shared with stakeholders including the Community Advisory Board (CAB) members during a partner education component of the study to finalize concepts to be covered in the biospecimen science education program. Dissemination activities require thoughtful planning, because there may be different audiences (e.g., CAB and community members) and time points within the research process that require their own feedback loops for sharing information as it is developed and analyzed. Likewise, how information is developed and analyzed requires consideration of the goal and transparency in why and how specific partners are included throughout the research process.

The HyM study involved multiple phases that fed into each other and led to the testing of a mobile lab unit that could be used to collect and process biospecimen donations from willing community members at onsite events in the community. Each phase of the research included specific activities and processes that were meant to assess, deliver, or support the intended research goals of the study (Fig. 20.1).

Step 3: Design Activities Using Best Practice Strategies

As with any type of research, there is an emphasis on scientific rigor and the process applied to draw conclusions from study findings. Community-based research will often vary with respect to the level of community partner involvement, and this is unique to each collaboration; however, in studies that apply CBPR methodology, there are accepted and best practice strategies that can be used to ensure scientific rigor while addressing the issues most relevant to the community [6]. Best practice strategies should be applied at all phases of the research process and considered as an opportunity to further integrate community partners as citizen scientists who are the rightful experts with respect to the communities they live in.

The HyM study applied best practice strategies throughout each component of the research process from study design to public dissemination (Table 20.2). The CBPR principles were followed from the onset of the grant writing process and applied to all steps of the educational tool development, implementation, and dissemination processes [7]. Ultimately the application of a CBPR approach served to broker communication among scientists and community stakeholders and members throughout the biospecimen science co-learning process. An important implication included a detailed understanding of methods for introducing biospecimen science to diverse communities such as the Hispanic community engaged in the HyM study.

Discussion and Lessons Learned

Hispanics represent a significant proportion of the diverse minority populations that make up the United States and are underrepresented in biomedical research studies and even more so in biospecimen banks [8, 9]. A growing number of cancer research studies include the collection of biospecimens as part of the research participation process. It is important that this rapidly evolving field of cancer research as it relates to precision medicine and/or immunotherapy not contribute to further gaps and disparities across the cancer care and research spectrum. The HyM study sought to engage and partner with an underserved Hispanic community to (1) understand their awareness and interest in biospecimen science (2) develop a community-based education program to increase awareness and facilitate informed decision-making with regard to biospecimen donation and (3) test the feasibility of community-engaged culturally appropriate approaches in recruiting diverse and underserved community participants to biospecimen donation for cancer research using a mobile lab unit for onsite collection and processing of biospecimen donations.

Most Hispanic groups do not have a historical context of mistrust with regard to the medical community. Other studies including Hispanics have also found that lack of awareness regarding biospecimen science and/or not having been asked to participate in cancer research are the primary reasons cited by this population regarding their lack of participation in biospecimen donation [2, 4, 9]. Cancer research opportunities inclusive of Hispanics are critical to understand the molecular differences in cancer cells compared to populations that have been better studied and represented in research [10]. Community-engaged studies have shown that several Hispanic groups indicate a willingness to donate biospecimens for cancer research and also support the use of trained non-medical staff to obtain consent for the biospecimen request [2, 11]. Engaging Hispanic communities in a culturally appropriate manner at the very beginning is necessary and essential to the collection of biospecimens for cancer research. This research requires a commitment to collaboration across disciplines and values community engagement as part of the research process.
