Deployment of Point-of-Care Echocardiography to Improve Cardiac Diagnostic Access Among American Indians.

Background: American Indians face significant barriers to diagnosis and management of cardiovascular disease. We sought to develop a real-world implementation model for improving access to echocardiography within the Indian Health Service, the American Indian Structural Heart Disease Partnership.

Methods And Results: The American Indian Structural Heart Disease Partnership was implemented and evaluated via a 4-step process of characterizing the system where it would be instituted, building point-of-care echocardiography capacity, deploying active case finding for structural heart disease, and evaluating the approach from the perspective of the clinician and patient.

Community Health Representative Workforce: Integration across systems and teams to address the social determinants of indigenous health and wellbeing.

Tribally employed, Community Health Representatives (CHRs) serving Indigenous and American Indian and Alaskan Native (AIAN) peoples are culturally and linguistically embedded community leaders, with the unique ability to serve as the link and intermediary between community members and systems. Unique to the CHR workforce scope of practice is the expectation for high level integration within the medical and social service care team. This explicit role outlined in the scope of work sets an expectation for both CHR and care teams to deliver integrated patient, family, and systems level care coordination and case management.

Community Health Representatives as Trusted Sources for Increasing Representation of American Indian Communities in Clinical Research.

Unlabelled: Indigenous and American Indian Alaskan Native (AI/AN) community members are systematically underrepresented in clinical trial research. This paper focuses on exploratory steps to partner with Native Nations of Arizona to engage Community Health Representatives (CHR) as a trusted source for building COVID-19 clinical trial research, including vaccine trials awareness. CHRs are frontline public health workers who apply a unique understanding of the experience, language, and culture of the population served.

Unique Genomic Epidemiology of COVID-19 in the White Mountain Apache Tribe, April to August 2020, Arizona.

The first case of coronavirus disease 2019 (COVID-19) within the White Mountain Apache Tribe (WMAT) in Arizona was diagnosed almost 1 month after community transmission was recognized in the state. Aggressive contact tracing allowed for robust genomic epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and subsequent phylogenetic analyses implicated only two virus introductions, which resulted in the spread of two unique viral lineages on the reservation. The phylogenies of these lineages reflect the nature of the introductions, the remoteness of the community, and the extraordinarily high attack rates.

Building Trust and Awareness to Increase AZ Native Nation Participation in COVID-19 Vaccines.

The goal of this study was to establish effective, culturally appropriate strategies to enhance participation of American Indian/Alaska Native (AI/AN) communities in prevention and treatment of COVID-19, including vaccine uptake. Thirteen Community Health Representatives (CHRs) from three Arizona Native nations tailored education materials to each community. CHRs delivered the intervention to over 160 community members and administered a pre-posttest to assess trusted sources of information, knowledge, and self-efficacy and intention regarding COVID-19 vaccines.
