Barriers and unmet needs related to healthcare for American Indian and Alaska Native communities: improving access to specialty care and clinical trials.

Substantial healthcare barriers, especially to specialty and cancer care, exist for American Indian and Alaska Native (AI/AN) individuals and communities at all levels. The unique history of AI/AN Tribal Nations and resulting policies, treaties, and relationships with the US government and federal agencies have created specific barriers to healthcare and clinical trial access for AI/AN peoples. Commonly, AI/AN peoples harbor a long-standing mistrust of the healthcare system based on lived and historical experiences. The intersection of various barriers to care for AI/AN communities results in health inequities, lack of representation in clinical research, and other disparities faced by historically marginalized and underrepresented peoples. AI/AN patients face unique barriers in their healthcare journey due to a disproportionate burden of life-threatening and chronic diseases, including many cancers. Identifying barriers specific to AI/AN peoples and improving access to high-quality care, with a focus on building on the strengths and capacities in each AI/AN community are vital to improving health equity. In this review, we describe patient, provider, and institutional barriers to healthcare, particularly specialty care and clinical research, for AI/AN peoples, with a focus on the Northern Plains AI communities. Examples and best practices to improve AI/AN patient access to health services, including screening and specialty care, as well as to clinical research, are provided. We emphasize the importance of longitudinal community-based partnerships and strength- and trust-based approaches as essential components of promoting equitable access to high-quality specialty care and recruitment and participation of AI/AN individuals and communities in clinical research.
