Barriers and Facilitators to Stool-Based Screening for Colorectal Cancer Among Black Louisville Residents.

Knowledge of colorectal cancer (CRC) screening options remains suboptimal in Black populations, contributing to screening disparities. Guided by community-based participatory research (CBPR) principles, we partnered with five Black churches in Louisville, a region of Kentucky with high Black-white CRC screening disparities, to explore screening barriers and facilitators for CRC education and outreach. Project champions (n = 5) served as primary points of contact, developed project support within their churches, and were trained to recruit church and community members (n = 39) to participate in five semi-structured focus groups. Interview questions probed actual and perceived barriers to CRC screening, focusing on knowledge and perceptions of stool-based tests. Subsequent questions explored perceptions of different screening tests, CRC knowledge and beliefs, and trusted community locations for screening outreach. Transcripts were analyzed iteratively, and codes were derived inductively and refined to develop overarching themes. Participants experienced multilevel barriers to completing CRC screening. Primary themes about CRC screening included acknowledgment of importance, positive and negative personal experiences, need for increased outreach, and desire for greater cultural representation in educational materials. Participants frequently discussed perceptions of inadequate medical care, with most having only ever been offered colonoscopy; subsequently, knowledge of stool-based tests was low. To address this knowledge gap, participants stressed interpersonal communication from trusted individuals, such as local Black medical providers and CRC survivors. Given the low knowledge of stool-based testing among participants and identified inequities in receipt of clinical care, community-based CRC screening interventions are warranted to reduce Black-white CRC screening disparities.

Using the consolidated framework for implementation research to identify church leaders' perspectives on contextual determinants of community-based colorectal cancer screening for Black Kentuckians.

BACKGROUND: Black Kentuckians experience more deleterious colorectal cancer (CRC) outcomes than their White counterparts, a disparity that could be reduced by increased screening in Black communities. Previous research has shown that Black Kentuckians may not be equitably informed of different CRC screening options by health care providers, making community-based screening a potentially effective option among this disparate population. We used the Consolidated Framework for Implementation Research (CFIR) to identify church leaders' perspectives of contextual factors that might influence community-based screening and explore the feasibility of using church-based screening outreach. METHODS: Six participants were selected, based on leadership roles and interest in CRC screening, from five established Louisville-area church partners that had previously participated in community health initiatives. Data were collected, both virtually and in-person, in Summer 2021 using semi-structured interview guides developed with guidance from the CFIR Guide that focused on domains most relevant to community-based interventions. Data were transcribed verbatim, coded by two independent researchers, and member checked for accuracy. RESULTS: Data were aligned primarily with six CFIR constructs: key stakeholders, champions, opinion leaders, tension for change, compatibility, and culture. Participants noted a strong tension for change in their community due to perceptions of inadequacy with clinical approaches to CRC screening. Additionally, they stressed the importance of identifying individuals both within the church who could champion CRC screening and help implement program activities, as well as those outside the church who could collaborate with other local organizations to increase participant reach. Finally, participants agreed that faith-based CRC screening aligned with church culture and would also likely be compatible with overall community values. CONCLUSIONS: Overall, our church partners strongly endorsed the need for, and importance of, community-based CRC screening. Given a history of successful implementation of health promotion programs within our partner churches, it is highly likely that a CRC screening intervention would also be effective. Findings from this study will be used to identify implementation strategies that might positively impact a future faith-based CRC screening intervention, as well as CFIR constructs that are most positively associated with CRC screening completion.
