Abstract Body:
American Indians (AIs) have lower colorectal cancer screening rates than other racial/ethnic populations in the nation. In New Mexico (NM), many AIs receive healthcare at the Indian Health Services (I), Tribal (T), and Urban Indian (U) healthcare facilities where implementation of colorectal cancer screening services (CRCS) is challenging. To understand how best to improve CRCS in these settings and among tribal communities, we conducted two focus groups with providers (n=15) and four focus groups or listening sessions with community members (n=65) in two NM communities. The discussions helped elicit input on appropriate patient-, provider-, and system-level strategies for promoting the uptake and delivery of CRCS in AI communities. While considering specific strategies for implementation, community members and providers highlighted implementation determinants that were unique to the AI communities in NM. Using a grounded theory approach, we identified three themes important for implementing CRCS in I/T/U healthcare facilities. First, several discussants mentioned the need for incorporating the context of NM's AI communities when implementing CRCS. For example, communicating with patients was preferable though text messages, mail, or home visits rather than phone calls. They also highlighted widespread fear of cancer and the very private AI culture, making it challenging to reach men and share experiences to motivate others in the community for CRCS. The need to incorporate intergenerational approaches, native languages, and tribal members as navigators was also underscored as a means to promote cultural congruency in sorely needed CRCS health education delivery. Second, several community members discussed the historical distrust in medical providers and healthcare settings as important reasons for not seeking healthcare. Third, several providers discussed operating healthcare settings under limited resources, resulting in fragmented referral networks and information systems and limited support for patient/provider reminder/recall systems. Using a community-based research approach allows for identifying determinants prior to implementation, thereby providing the opportunity to understand and address these for sustainable implementation of CRCS.
