Abstract B120: Understanding Barriers and Facilitators Affecting Participation in Cancer Clinical Research Studies for Racially and Ethnically Diverse Populations in Rural North Carolina

Abstract

Abstract Increasing representation of minoritized racial and ethnic populations in cancer clinical research studies has been declared a priority in the US for many years. Additionally, it is widely recognized that people living in rural areas of the US have limited access to cancer clinical research studies, and solutions are needed to extend participation opportunities to rural cancer patients. Underrepresentation of minoritized racial and ethnic populations and rural communities perpetuates health inequities, and solutions are needed to remove barriers and implement facilitators for participation. However, a review of existing literature found a lack of attention on the intersection of race and rurality and the needs and values of these populations as it pertains to cancer research. To address this concern, we used a sequential mixed method, community-engaged approach to explore the barriers and facilitators affecting participation in cancer clinical research from the perspectives of cancer survivors and their caregivers, as well as cancer healthcare professionals in rural North Carolina (NC). We used existing publicly available data to identify and characterize four of the most rural, racially and ethnically diverse, and medically underserved counties in NC. The principal investigator collaborated with cancer centers, churches, and American Indian tribal leaders in NC to administer surveys to cancer survivors and caregivers to assess their beliefs and experiences regarding cancer clinical research. Eligible participants included persons who had been diagnosed with cancer or a caregiver of someone diagnosed with cancer. In addition, we conducted key informant interviews with cancer health care professionals providing cancer care in the selected rural NC counties. We analyzed surveys and interview responses with descriptive statistics. Forty-three cancer survivors/caregivers completed surveys and twenty-two cancer healthcare professionals completed semi-structured interviews. Cancer survivors and caregivers indicated that the lack of invitation to participate in cancer clinical research was their greatest barrier to participation, whereas cancer healthcare professionals cited the lack of transportation as the perceived greatest barrier for patients. Cancer survivors, caregivers and healthcare professionals agreed that having support from clinical research personnel would be amongst the most helpful facilitators, along with opportunities to participate in clinical research studies close to home. Cancer healthcare professionals suggested the lack of trust in clinical research was a barrier for their patients; however, cancer survivors and caregivers in this study indicated lack of trust was not a significant barrier to their participation. Recommendations to address barriers and promote facilitators to participation in cancer clinical research include the importance of engaging the community, addressing unconscious bias, decentralizing clinical trials, and providing recruitment materials in culturally responsive formats.
