Trends in rheumatoid arthritis associated cardiovascular mortality in the United States from 1999 to 2020

INTRODUCTION

Rheumatoid Arthritis (RA) is a risk enhancing factor for cardiovascular diseases (CVD). However, data regarding the magnitude and trends of RA associated CVD-related mortality in the United States (U.S) remains scarce.

METHODS

A retrospective analysis was conducted using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) dataset. We extracted age-adjusted mortality rates (AAMR) per 100,000 persons and calculated the annual percentage change (APC) through Joinpoint regression. The outcomes were stratified to discern temporal, sex-based, racial, and geographic patterns in RA-associated CVD mortality.

RESULTS

Between 1999 and 2020, 128,058 deaths related to CVD in RA patients aged 25 and above were recorded. The AAMR decreased from 3.50 in 1999 to 2.79 in 2020. However, sex disparities persisted, with females consistently experiencing a higher AAMR (3.35) compared to males (1.74). Non-Hispanic (NH) American Indian/Alaska Native had the highest AAMR (4.44) followed by NH White (2.83), NH Black or African American (2.47) and Hispanic or Latino (2.13), while NH Asian/Pacific Islander had the lowest AAMR (1.28). Geographically, the Midwestern region had the highest AAMR (3.12), while the Northeast had the lowest (2.19) with micropolitan (3.47) and nonmetropolitan (3.37) areas exhibiting higher AAMRs compared to large metropolitans (2.28). Notably, states with the highest AAMRs included North Dakota, South Dakota, Vermont, Minnesota and Wyoming.

CONCLUSION

Recent trends reveal an upward incline in RA-associated CVD-related mortality with profound disparities related to sex, race, geography and regions. Redressing these disparities necessitates the implementation of targeted population level interventions.

Place-based strengths and vulnerabilities for mental wellness among rural minority older adults: an intervention development study protocol

INTRODUCTION

Severe inequities in depression and its diagnosis and treatment among rural-dwelling, racial-minority and ethnic-minority older adults compared with their urban white counterparts result in cognitive impairment, comorbidities and increased mortality, presenting a growing public health concern as the United States (US) population ages. These inequities are often attributable to social and environmental factors, including economic insecurity, histories of trauma, gaps in transportation and safety-net services, and disparities in access to policy-making processes rooted in colonialism. This constellation of factors renders racial-minority and ethnic-minority older adults 'structurally vulnerable' to mental ill health. Fewer data exist on protective factors associated with social and environmental contexts, such as social support, community attachment and a meaningful sense of place. Scholarship on the social determinants of health widely recognises the importance of such place-based factors. However, little research has examined how they shape disparities in depression and treatment specifically, limiting the development of practical approaches addressing these factors and their effects on mental well-being for rural minority populations.

METHODS AND ANALYSIS

This community-driven mixed-method study uses quantitative surveys, qualitative interviews and ecological network research with 125 rural American Indian and Latinx older adults in New Mexico and 28 professional and non-professional social supporters to elucidate how place-based vulnerabilities and protective factors shape experiences of depression among older adults. Data will serve as the foundation of a community-driven plan for a multisystem intervention focused on the place-based causes of disparities in depression. Intervention Mapping will guide the intervention development process.

ETHICS AND DISSEMINATION

This study has been reviewed and approved by the University of New Mexico Health Sciences Center Institutional Review Board. All participants will provide informed consent. Study results will be disseminated within the community of study through community meetings and presentations, as well as broadly via peer-reviewed journals, conference presentations and social media.

State-Federal Vocational Rehabilitation Services, Demographic Characteristics and Employment Outcomes for Native Americans with Mental Illnesses

There were 9.7 million Native Americans (American Indian, Alaska Native-AI/AN- these acronyms will be used interchangeably with Native Americans throughout the paper) in 2019 comprising 2.9% of the U.S. population. Native American populations have disproportionately higher rates of mental illnesses compared to other racial groups in the U.S. Mental health is a significant public health concern for this population, impacting different areas of their lives including employment. Additionally, Native Americans continue to experience significant disparities in access to Vocational Rehabilitation (VR) services and have poor employment outcomes. However, little is known about the relationships among demographic factors, vocational rehabilitation services, and employment outcomes of Native Americans with mental illness. Consequently, the current study examined how demographic factors and VR services are related to successful employment outcomes for Native American VR clients with mental illnesses using data from the Rehabilitation Services Administration (RSA) program year (2019) Case Service Report (9-11). Both descriptive analysis and data mining approaches were used to answer the research questions. Chi-square Automatic Interaction Detector (CHAID) analysis was used to determine which of the VR services could best predict the successful employment outcome of Native Americans with mental illness. The findings of the data mining approach revealed that among all the vocational rehabilitation services, job placement assistance was the strongest predictor of successful employment among Native American clients with mental illnesses. The second most important service predicting successful employment for those who received job placement assistance was shown to be maintenance. Implications for rehabilitation counselors and future research are discussed.

"'We'd Just Patch Ourselves up': Preference for Holistic Approaches to Healthcare and Traditional Medicine among Members of a State-Recognized Tribe"

Background:Health disparities between Native Americans and white Americans persist due to a variety of factors, including colonization, poverty, and racism. Racist interpersonal interactions between nurses and other healthcare providers and tribal members may also contribute to reluctance among Native Americans to engage with Western healthcare systems. Purpose: The purpose of this study was to better understand the healthcare experiences of members of a state-recognized Gulf Coast tribe. Methods: In partnership with a community advisory board, 31 semistructured interviews were conducted, transcribed, and analyzed utilizing a qualitative description approach. Results: All participants mentioned their preferences, views about, or experiences of using natural or traditional medicine approaches (referenced 65 times). Emergent themes include (a) preference for and use of traditional medicine; (b) resistance to western healthcare systems; (c) preference for holistic approaches to health; and (d) negative provider interpersonal interactions contributing to reluctance in seeking care. Conclusion: These findings suggest that integrating a holistic conceptualization of health and traditional medicine practices into Western healthcare settings would benefit Native Americans.

National Norms for Hospitalizations Due to Ambulatory Care Sensitive Conditions among Adults in the US

BACKGROUND

Ambulatory care sensitive conditions (ACSCs) are acute or chronic health issues that lead to potentially preventable hospitalizations when not treated in the outpatient primary care setting.

OBJECTIVE

To describe national hospitalization rates due to ACSCs among adult inpatients in the US.

DESIGN

A retrospective cross-sectional analysis of the 2018 US National Inpatient Sample (NIS) dataset from the Healthcare Cost and Utilization Project at the Agency of Healthcare Research and Quality was completed in the year 2022.

PARTICIPANTS

Participants were adult inpatients from community hospitals in 48 states of the US and District of Columbia.

MAIN MEASURES

ACSC admission rates were calculated using ICD-10 codes and the Purdy ACSC definition. The admission rates were weighted to the US inpatient population and stratified by age, sex, and race.

KEY RESULTS

ACSC hospitalization rates varied considerably across age and average number of hospitalizations varied across sex and race. ACSC hospitalization rates increased with age, male sex, and Native American and Black race. The most common ACSCs were pneumonia, diabetes, and congestive heart failure.

CONCLUSIONS

Previous studies have emphasized the importance of preventable hospitalizations, however, the national rates for ACSC hospitalizations across all ages in the US have not been reported. The national rates presented will facilitate comparisons to identify hospitals and health care systems with higher-than-expected rates of ACSC admissions that may suggest a need for improved primary care services.

Alzheimer's disease and its related dementias in US Native Americans: A major public health concern

Alzheimer's disease (AD) and Alzheimer's related dementias (ADRD) are growing public health concerns in aged populations of all ethnic and racial groups. AD and ADRD are caused by multiple factors, such as genetic mutations, modifiable and non-modifiable risk factors, and lifestyle. Studies of postmortem brains have revealed multiple cellular changes implicated in AD and ADRD, including the accumulation of amyloid beta and phosphorylated tau, synaptic damage, inflammatory responses, hormonal imbalance, mitochondrial abnormalities, and neuronal loss. These changes occur in both early-onset familial and late-onset sporadic forms. Two-thirds of women and one-third of men are at life time risk for AD. A small proportion of total AD cases are caused by genetic mutations in amyloid precursor protein, presenilin 1, and presenilin 1 genes, and the APOE4 allele is a risk factor. Tremendous research on AD/ADRD, and other comorbidities such as diabetes, obesity, hypertension, and cancer has been done on almost all ethnic groups, however, very little biomedical research done on US Native Americans. AD/ADRD prevalence is high among all ethnic groups. In addition, US Native Americans have poorer access to healthcare and medical services and are less likely to receive a diagnosis once they begin to exhibit symptoms, which presents difficulties in treating Alzheimer's and other dementias. One in five US Native American people who are 45 years of age or older report having memory issues. Further, the impact of caregivers and other healthcare aspects on US Native Americans is not yet. In the current article, we discuss the history of Native Americans of United States (US) and health disparities, occurrence, and prevalence of AD/ADRD, and shedding light on the culturally sensitive caregiving practices in US Native Americans. This article is the first to discuss biomedical research and healthcare disparities in US Native Americans with a focus on AD and ADRD, we also discuss why US Native Americans are reluctant to participate in biomedical research.

"Treat Me like Your Family": Positive Factors that Influence Patient-Provider Relationships for Native American Women

Although extensive documentation of the health disparities experienced by Native American peoples exists, little research explores experiences of members of non-federally recognized tribes who receive health care outside of the Indian Health Services (IHS) system. Additionally, positive factors that influence relationships between health care providers and tribal members are understudied and are needed to promote health care access. A qualitative descriptive methodologic approach was used to conduct semi structured life history interviews with 31 women who identified as members of a state-recognized, Gulf South Native American tribe. Results identified the following important themes: Do Participants Have a Regular Provider, Personal Relationship With Provider, Feel Provider Cares, Provider Addresses Concern, and Respect for Traditional or Holistic Medicine. These findings suggest health care providers play an important role in impacting the health care experiences of Native American tribal members. Implications for trainings for health care providers are discussed.

Contemporary Trends in Acute Myocardial Infarction in the American Indian/Alaska Native U.S. Population, 2000 to 2018

Coronary heart disease is disproportionately prevalent in the American Indian/Alaska Native (AI/AN) population. As care for acute myocardial infarction (AMI) continues to advance, equitable distribution and access for the AI/AN population is essential. Primary AMI hospitalizations for adults ≥18 years of age were identified from the Healthcare Cost and Utilization Project National Inpatient Sample from 2000 to 2018. Related co-morbidities, procedures of interest, and in-hospital mortality were also identified. These rates were stratified by race then trended over years using Poisson regression. Overall, 9,904,714 weighted hospitalizations for primary AMI were identified. From 2000 to 2018, AI/AN adults had relatively high rates of primary AMI hospitalization, second only to non-Hispanic (NH) White adults. The AMI rate increased from 14.0/1,000 to 16.1/1,000 among AI/AN adults, remaining higher than NH Black adults (12.1/1,000 to 13.0/1,000) and Hispanic adults (10.3/1,000 and 12.7/1,000) and becoming increasingly closer to NH White adults (25.1/1,000 to 20.0/1,000) (p <0.001 for each). AI/AN adults presented 5 years earlier than their NH White counterparts (64 vs 69 years old; p <0.001). In-hospital mortality was approximately 5% for all race categories and decreased in all groups but decreased at a much greater rate for NH White, NH Black and Hispanic adults (0.2% per year) compared with AI/AN adults (0.08% per year; p <0.001 for each comparison). Rates of coronary angiography and percutaneous coronary intervention increased in all groups, but coronary artery bypass graft utilization increased only in AI/AN adults (from 7% to 10%, p <0.001). In conclusion, from 2000 to 2018, AI/AN adults had a high rate of AMI hospitalizations (second only to NH White adults) that increased significantly over time. AI/AN adults were 5 years younger than their NH White counterparts at index AMI hospitalization. Care during these hospitalizations was similar among all racial groups, and in-hospital mortality decreased for all groups, albeit to a lesser degree among AI/AN adults. This study highlights the need for improved access to outpatient primary AMI prevention in the AI/AN population.

"I Think [Western] Healthcare Fails Them": Qualitative Perspectives of State-recognized Women Tribal Members on Elders' Healthcare Access Experiences

Elder tribal members are important cultural and spiritual leaders and experts among many American Indian and Alaska Native (AI/AN) cultures. AI/AN Elders play a key role in the maintenance and transmission of traditional cultural knowledge and practices and are highly valued members of AI/AN communities. AI/AN populations face disparities in healthcare outcomes, and the healthcare needs of AI/AN Elders remain an understudied area of research, particularly among tribes in the South and for tribes who do not have federal recognition. Qualitative data was collected through semi-structured interviews among 31 women, all of whom are members of a state-recognized Tribe in the Southern United States. While the interview questions were specific to their own reproductive healthcare experiences, repeated concerns were voiced by the women regarding the health of the Elders in their community. Key findings captured several concerns/barriers regarding Elders' healthcare experiences including: (a) Language and communication barriers between Elders and healthcare workers; (b) Prior negative experiences with Western medicine; (c) Lasting impacts of educational discrimination; (d) Concerns over self-invalidation; (e) Transportation barriers; and (f) Need for community programs. Issues related to these barriers have resulted in a concern that Elders are not receiving the full benefit of and access to Western healthcare systems. The purpose of this analysis was to highlight the concerns voiced by women tribal members on the health and wellbeing of Elders in their community. Opportunities related to the importance of prioritizing and improving AI/AN Elders' healthcare experiences and access are also described.

Addressing Financial Barriers to Health Care Among People Who are Low-Income and Insured in New York City, 2014–2017

While health care-associated financial burdens among uninsured individuals are well described, few studies have systematically characterized the array of financial and logistical complications faced by insured individuals with low household incomes. In this mixed methods paper, we conducted 6 focus groups with a total of 55 residents and analyzed programmatic administrative records to characterize the specific financial and logistic barriers faced by residents living in public housing in East and Central Harlem, New York City (NYC). Participants included individuals who enrolled in a municipal community health worker (CHW) program designed to close equity gaps in health and social outcomes. Dedicated health advocates (HAs) were explicitly paired with CHWs to provide health insurance and health care navigational assistance. We describe the needs of 150 residents with reported financial barriers to care, as well as the navigational and advocacy strategies taken by HAs to address them. Finally, we outline state-level policy recommendations to help ameliorate the problems experienced by participants. The model of paired CHW–HAs may be helpful in addressing financial barriers for insured populations with low household income and reducing health disparities in other communities.

Supporting the Health and Well-Being of Indigenous Communities: A Position Paper From the American College of Physicians

Indigenous peoples in the United States experience many health disparities and barriers to accessing health care services. In addition, Indigenous communities experience poor social drivers of health, including disproportionately high rates of food insecurity, violence, and poverty, among others. These challenges are unsurprising, given historical societal discrimination toward Indigenous peoples and government policies of violence, forced relocation with loss of ancestral home, and erasure of cultures and traditions. Indigenous peoples have displayed resilience that has sustained their communities through these hardships. Through treaties between the federal government and Indigenous nations, the federal government has assumed a trust responsibility to provide for the health and well-being of Indigenous populations through the direct provision of health care services and financial support of tribally operated health systems. However, despite serving a population that has endured substantial historical trauma and subsequent health issues, federal programs serving Indigenous peoples receive inadequate federal funding and substantially fewer resources compared with other federal health care programs. Access to care is further challenged by geographic isolation and health care workforce vacancies. Given the history of Indigenous peoples in the United States and their treatment by the federal government and society, the American College of Physicians (ACP) asserts the federal government must faithfully execute its trust responsibility through increased funding and resources directed toward Indigenous communities and the undertaking of concerted policy efforts to support the health and well-being of Indigenous people. ACP believes that these efforts must be community-driven, Indigenous-led, and culturally appropriate and accepted, and center values of respect and self-determination.

The Unmet Need for Orthopaedic Services Among American Indian and Alaska Native Communities in the United States

ABSTRACT

Historic and present-day marginalization has resulted in a high burden of disease and worse health outcomes for American Indian and Alaska Native (AI/AN) communities in the United States. Musculoskeletal disease is the leading cause of disability for the general population in the U.S. today. However, few have examined musculoskeletal disease burden and access to orthopaedic surgical care in the AI/AN communities. A high prevalence of hip dysplasia, arthritis, back pain, and diabetes, and a high incidence of trauma and road traffic-related mortality, suggest a disproportionately high burden of musculoskeletal pathology among the AI/AN communities and a substantial need for orthopaedic surgical services. Unfortunately, AI/AN patients face many barriers to receiving specialty care, including long travel distances and limited transportation to health facilities, inadequate staff and resources at Indian Health Service (IHS)-funded facilities, insufficient funding for referral to specialists outside of the IHS network, and sociocultural barriers that complicate health-system navigation and erode trust between patients and providers. For those who manage to access orthopaedic surgery, AI/AN patients face worse outcomes and more complications than White patients. There is an urgent need for orthopaedic surgeons to participate in improving the availability of quality orthopaedic services for AI/AN patients through training and support of local providers, volunteerism, advocating for a greater investment in the IHS Purchased/Referred Care program, expanding telemedicine capabilities, and supporting community-based participatory research activities.

Experiences of Health Insurance among American Indian Elders and Their Health Care Providers

CONTEXT

American Indian elders have a lower life expectancy than other aging populations in the United States because of inequities in health and in access to health care. To reduce such disparities, the 2010 Affordable Care Act included provisions to increase insurance enrollment among American Indians. Although the Indian Health Service remains underfunded, increases in insured rates have had significant impacts among American Indians and their health care providers.

METHODS

From June 2016 to March 2017, we conducted qualitative interviews with 96 American Indian elders (age 55+) and 47 professionals (including health care providers, outreach workers, public-sector administrators, and tribal leaders) in two southwestern states. Interviews focused on elders' experiences with health care and health insurance. We analyzed transcripts iteratively using open and focused coding techniques.

FINDINGS

Although tribal health programs have benefitted from insurance payments, the complexities of selecting, qualifying for, and maintaining health insurance are often profoundly alienating and destabilizing for American Indian elders and communities.

CONCLUSIONS

Findings underscore the inadequacy of health-system reforms based on the expansion of private and individual insurance plans in ameliorating health disparities among American Indian elders. Policy makers must not neglect their responsibility to directly fund health care for American Indians.

Minority Enrollment in Phase II and III Clinical Trials in Urologic Oncology

PURPOSE

Proportionate minority representation in clinical trials is an important step toward addressing health care inequities. Given the paucity of data on this topic in urologic oncology, we sought to quantify the enrollment of minority patients in clinical trials studying prostate, kidney, and bladder/urothelial cancers.

METHODS

The ClincialTrials.gov database was queried for completed phase II and III interventional trials in prostate, kidney, and bladder cancers. The SEER database was used to calculate the US prevalence of these genitourinary cancers. Representation quotients (RQ) were calculated to describe the relative proportion of each racial/ethnic group enrolled in clinical trials over the proportion of persons from each group among national cancer cases by cancer type.

RESULTS

Of 341 trials that met initial eligibility criteria, only 169 (49.7%) reported data on race or ethnicity. Aggregate RQs from 2000 to 2017 showed that White patients were continually over-represented in trials for all cancer types. Black and Asian patients were poorly represented across all cancer types. When stratified by 3-year increments, the RQs remained stable for all races, from 2000 to 2017. When stratified by ethnicity, Hispanic patients were under-represented across all cancer types in the study period. When examining representation by funding source, we found that US government-funded clinical trials proportionally enroll the most diverse patient populations over those funded by academic institutions and industry. Interestingly, more than 50% of the trials examined did not report race nor ethnicity, highlighting a crucial flaw in investigator compliance with federal clinical trial mandates.

CONCLUSION

Clinical trials targeting prostate, kidney, and bladder cancers continue to under-represent racial/ethnic minority patients. On the basis of the incidence of these cancers within minority populations, efforts should focus on creating racially and ethnically inclusive cancer research.

Causes and Consequences of Not Having a Personal Healthcare Provider Among American Indian Elders: A Mixed-Method Study

Having a regular relationship with a healthcare provider contributes to better health outcomes and greater satisfaction with care for older adults. Although members of federally recognized American Indian tribes have a legal right to healthcare, American Indian Elders experience inequities in healthcare access that may compromise their ability to establish a relationship with a healthcare provider. This multi-year, community-driven, mixed-method study examines the potential causes and consequences of not having a personal healthcare provider among American Indian Elders. Quantitative surveys and qualitative interviews were conducted with 96 American Indian Elders (age 55 and over) in two states in the Southwestern United States. Quantitative and qualitative data were analyzed separately and then triangulated to identify convergences and divergences in data. Findings confirmed that having a consistent healthcare provider correlated significantly with self-rated measures of health, confidence in getting needed care, access to overall healthcare, and satisfaction with care. Lack of a regular healthcare provider was related to interconnected experiences of self-reliance, bureaucratic and contextual barriers to care, and sentiments of fear and mistrust based in previous interactions with medical care. Increasing health equity for American Indian Elders will thus require tailored outreach and system change efforts to increase continuity of care and provider longevity within health systems and build Elders' trust and confidence in healthcare providers.

Social Support and Psychological Distress among the Bedouin Arab Elderly in Israel: The Moderating Role of Gender

In Israel, as in other developed countries, mental health problems are common among older adults who are members of disadvantaged ethnic minorities that are experiencing cultural and social changes. The main goals of the current study were: (a) to examine gender differences in the levels of psychological distress and social support among Bedouin elders, and (b) to examine the moderating role of gender in the associations between social support indices and psychological distress. We used a cross-sectional design, and independent t-tests and hierarchical linear regression analysis were performed. The study was conducted in homes and in social clubs and community centers for elderly people and involved face-to-face interviews and self-administered questionnaires. A convenience sample of 170 Bedouin Arab elderly people living in Israel participated in the study. Participants completed self-report questionnaires that assessed psychological distress, perceived social support, instrumental social support, and socio-demographic characteristics. Male elders reported lower levels of psychological distress and higher levels of instrumental support. Female elders, who reported low levels of both perceived and instrumental support, also reported higher levels of psychological distress. Among the women, there were significant associations between psychological distress and perceived social support, and instrumental support only when the levels of support were low. This study underscores the moderating role of gender in the associations between different types of social support and psychological distress among elderly people belonging to ethnic and cultural underprivileged minority groups.

Healthcare experiences of uninsured and under-insured American Indian women in the United States

BACKGROUND

Extensive health disparities exist for American Indian groups throughout the United States. Although insurance status is linked to important healthcare outcomes, this topic has infrequently been explored for American Indian tribes. For state-recognized tribes, who do not receive healthcare services through the Indian Health Service, this topic has yet to be explored. The purpose of this study is to explore how having limited access to health insurance (being uninsured or under-insured) impact American Indian women's healthcare experiences?.

METHODS

In partnership with a community advisory board, this study used a qualitative description approach to conduct thirty-one semi-structured life-course interviews with American Indian women who are members of a state-recognized tribe in the Gulf Coast (United States) to explore their Western healthcare experiences. Interview were conducted at community centers, participant homes, and other locations identified by participants. Interviews were transcribed verbatim and findings were analyzed in NVivo using conventional content analysis. Findings were presented at tribal council meetings and to participants for member checking.

RESULTS

Themes identified by participants included: (a) lack of insurance as a barrier to healthcare; (b) pre-paying for childbirth when uninsured; and (c) access to public health insurance coverage. Twenty-four women mentioned the role or importance of insurance in discussing their healthcare experiences, which was referenced a total of 59 times.

CONCLUSION

These findings begin to fill an important gap in the literature about the health insurance experiences of American Indian tribal members. Not having insurance was an important concern for participants, particularly for elderly and pregnant tribal members. Not having insurance also kept tribal members from seeking healthcare services, and from getting needed prescriptions. In addition to promoting knowledge about, and expanding insurance options and enrollment, increased sovereignty and resources for state-recognized tribes is needed to address the health disparities experienced by American Indian groups.

The Community as the Unit of Healing: Conceptualizing Social Determinants of Health and Well-Being for Older American Indian Adults

Background and Objectives

Multiple racial and social inequities shape health and access to health care for American Indian Elders, who have a lower life expectancy than all other aging populations in the United States. This qualitative study examines how upstream social determinants of health influence Elders’ ability to access and use health care.

Research Design and Methods

Between June 2016 and March 2017, we conducted individual, semistructured interviews with 96 American Indian Elders, aged 55 and older, and 47 professionals involved in planning or delivering care to Elders in 2 states in the U.S. Southwest. Transcripts were analyzed iteratively using grounded theory approaches, including open and focused coding. A group of American Indian Elders and allies called the Seasons of Care Community Action Board guided interpretation and prioritization of findings.

Results

Participants described multiple barriers that hindered Elders’ ability to access health care services and providers, which were largely tied to funding shortages and bureaucratic complexities associated with health care and insurance systems. Where available, community resources bridged service gaps and helped Elders navigate systems.

Discussion and Implications

Longstanding structural inequities for American Indians manifest in barriers to health equity, many of which are situated at the community level. These are compounded by additional disparities affecting older adults, rural residents, and marginalized citizens in general. Findings underscore the importance of health and policy initiatives for American Indian Elders that emphasize the community as the focus of intervention.

Equity in healthcare access and service coverage for older people: a scoping review of the conceptual literature

There is currently no global review of the conceptual literature on the equity of healthcare coverage (including access) for older people. It is important to understand the factors affecting access to health and social care for this group, so that policy and service actions can be taken to reduce potential inequities. A scoping review of published and grey literature was conducted with the aim of summarising how health and social care service access and coverage for older people has been conceptualised. PubMed, MEDLINE, PsycINFO, CINAHL, Web of Science, SciELO, LILACS, BIREME and Global Index Medicus were searched. Selection of sources and data charting were conducted independently by two reviewers. The database searches retrieved 10 517 citations; 32 relevant articles were identified for inclusion from a global evidence base. Data were summarised and a meta-framework and model produced listing concepts specific to equitable health and social care service coverage relating to older people. The meta-framework identified the following relevant factors: acceptability, affordability, appropriateness, availability and resources, awareness, capacity for decision-making, need, personal social and cultural circumstances, physical accessibility. This scoping review is relevant to the development and specification of policy for older people. It conceptualises those factors, such as acceptability and affordability, that affect an older person's ability and capacity to access integrated, person-centred health and social care services in a meaningful way. These factors should be taken into account when seeking to determine whether equity in service use or access is being achieved for older people.

Representation of American Indian and Alaska Native Individuals in Academic Medical Training

IMPORTANCE

Identifying gaps in inclusivity of Indigenous individuals is key to diversifying academic medical programs, increasing American Indian and Alaska Native representation, and improving disparate morbidity and mortality outcomes in American Indian and Alaska Native populations.

OBJECTIVE

To examine representation of American Indian and Alaska Native individuals at different stages in the 2018-2019 academic medical training continuum and trends (2011-2020) of American Indian and Alaska Native representation in residency specialties.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional, population-based analysis was conducted using self-reported race and ethnicity data on trainees from the Association of American Medical Colleges (2018), the Accreditation Council for Graduate Medical Education (2011-2018), and the US Census (2018). Data were analyzed between February 18, 2020, and March 4, 2021.

EXPOSURES

Enrolled trainees at specific stages of medical training.

MAIN OUTCOMES AND MEASURES

The primary outcome was the odds of representation of American Indian and Alaska Native individuals at successive academic medical stages in 2018-2019 compared with White individuals. Secondary outcomes comprised specialty-specific proportions of American Indian and Alaska Native residents from 2011 to 2020 and medical specialty-specific proportions of American Indian and Alaska Native physicians in 2018. Fisher exact tests were performed to calculate the odds of American Indian and Alaska Native representation at successive stages of medical training. Simple linear regressions were performed to assess trends across residency specialties.

RESULTS

The study data contained a total of 238 974 607 White and American Indian and Alaska Native US citizens, 24 795 US medical school applicants, 11 242 US medical school acceptees, 10 822 US medical school matriculants, 10 917 US medical school graduates, 59 635 residents, 518 874 active physicians, and 113 168 US medical school faculty. American Indian and Alaska Native individuals had a 63% lower odds of applying to medical school (odds ratio [OR], 0.37; 95% CI, 0.31-0.45) and 48% lower odds of holding a full-time faculty position (OR, 0.52; 95% CI, 0.44-0.62) compared with their White counterparts, yet had 54% higher odds of working in a residency specialty deemed as a priority by the Indian Health Service (OR, 1.54; 95% CI, 1.09-2.16). Of the 33 physician specialties analyzed, family medicine (0.55%) and pain medicine (0.46%) had more than an average proportion (0.41%) of American Indian and Alaska Native physicians compared with their representation across all specialties.

CONCLUSIONS AND RELEVANCE

This cross-sectional study noted 2 distinct stages in medical training with significantly lower representation of American Indian and Alaska Native compared with White individuals. An actionable framework to guide academic medical institutions on their Indigenous diversification and inclusivity efforts is proposed.

[Application of conceptual mapping in the regulation of access to public health services in the Federal District, Brazil]

Health regulation in the pursuit of equity is the goal of management and requires evaluation methods that improve work processes. The scope of this article is to analyze the application of conceptual mapping in the regulation of access to public health services. It is an exploratory and descriptive study, using a mixed approach, carried out at the Health Regulatory Complex of the Federal District. The data were collected between August and October 2019 and analyzed with the assistance of IRaMuTeQ and Concept Systems® software. There is a convergence of the 25 statements generated by the 71 participants, grouped into 4 clusters, on regulation towards the principle of equity. The healthcare priority level was presented as the focus of regulation and management, the driving force behind the integration of processes. Conceptual mapping is a tool that can support regulation planning and evaluation, as it makes it possible to identify priority points to be worked on by management in improving the regulatory processes identified in this study. These include the training of professionals, the transparency of information and the level of priority healthcare, for effective, equitable, rational and timely access for users of the health system.

Getting to Know: American Indian Elder Health Seeking in an Under-funded Healthcare System

American Indian (AI) Elders are the heart of the community. Existing research explores links between specific health behaviors and social determinants of health, but there is little theory explaining patient behaviors in the context of the Indian Health Service (IHS) system of care. We drew from a multiyear mixed-methods participatory study of Elder healthcare experiences to identify the systemic, interpersonal, and historic factors in the IHS that impact their health-seeking behaviors. We conducted an interpretive grounded theory analysis guided by Indigenous methodologies to analyze interviews with 96 AI Elders from two Southwestern states. Our resulting theory, Getting to Know, explains how Elders knew, owned, accessed, and were denied information and resources in their efforts to receive care. Findings highlight how Elders' health-seeking behaviors reflect longstanding inequities, the many ways Elder knowledge was incongruent with Western knowledge embedded in the IHS system, and how this conflict contributed to Elder discomfort in clinical settings. Future work will test the applicability of Getting to Know in other AI communities and design culturally safe care to meet Elder needs. By applying an Indigenous-centered analysis to the voices of Elders, we identified key influences on health outcomes not previously observed in the literature. By illuminating these influences, we show how culturally safe care can be better formulated to meet the needs of Elders, ultimately improving health for AI communities.

Health Care Access and Utilization for American Indian Elders: A Concept-Mapping Study

OBJECTIVES

Inequities in access to and utilization of health care greatly influence the health and quality of life of American Indian elders (AIEs). This study explores the importance and perceived prevalence of factors affecting health care use within this population and assesses the changeability of these factors to produce a list of action items that are timely and relevant to improving health care access and utilization.

METHOD

Concept mapping was conducted with AIEs (n = 65) and professional stakeholders (n = 50), including tribal leaders, administrators of public-sector health systems, outreach workers, and health care providers. Data were analyzed using multidimensional scaling and cluster analyses.

RESULTS

The final concept-map model comprised nine thematic clusters related to factors affecting elder health care: Difficulties Obtaining and Using Insurance; Insecurity from Lack of Knowledge; Limited Availability of Services; Scheduling Challenges; Provider Issues and Relationships; Family and Emotional Challenges; Health-Related Self-Efficacy and Knowledge; Accessibility and Transportation Barriers; and Tribal/National Policy.

DISCUSSION

Findings suggest that improvements in access to and utilization of health care among AIEs will require actions across multiple domains, including health system navigation services, workforce improvements, and tribal, state, and federal policy. A multilevel socioecological approach is necessary to organize and undertake these actions.

Macro- and meso-level contextual influences on health care inequities among American Indian elders

BACKGROUND

American Indian elders, aged 55 years and older, represent a neglected segment of the United States (U.S.) health care system. This group is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other aging populations in the country. Despite the U.S. government's federal trust responsibility to meet American Indians' health-related needs through the Indian Health Service (IHS), elders are negatively affected by provider shortages, limited availability of health care services, and gaps in insurance. This qualitative study examines the perspectives of professional stakeholders involved in planning, delivery of, and advocating for services for this population to identify and analyze macro- and meso-level factors affecting access to and use of health care and insurance among American Indian elders at the micro level.

METHODS

Between June 2016 and March 2017, we undertook in-depth qualitative interviews with 47 professional stakeholders in two states in the Southwest U.S., including health care providers, outreach workers, public-sector administrators, and tribal leaders. The interviews focused on perceptions of both policy- and practice-related factors that bear upon health care inequities impacting elders. We analyzed iteratively the interview transcripts, using both open and focused coding techniques, followed by a critical review of the findings by a Community Action Board comprising American Indian elders.

RESULTS

Findings illuminated complex and multilevel contextual influences on health care inequities for elders, centering on (1) gaps in elder-oriented services; (2) benefits and limits of the Affordable Care Act (ACA); (2) invisibility of elders in national, state, and tribal policymaking; and (4) perceived threats to the IHS system and the federal trust responsibility.

CONCLUSIONS

Findings point to recommendations to improve the prevention and treatment of illness among American Indian elders by meeting their unique health care and insurance needs. Policies and practices must target meso and macro levels of contextual influence. Although Medicaid expansion under the ACA enables providers of essential services to elders, including the IHS, to enhance care through increased reimbursements, future policy efforts must improve upon this funding situation and fulfill the federal trust responsibility.

Exercise-based interventions for Indigenous adults with chronic lung disease in Australia, Canada, New Zealand, and USA: a systematic review

Indigenous peoples in Australia, New Zealand, Canada, and the United States of America (USA) have a higher burden of chronic lung disease than non-Indigenous people. Exercised-based interventions, such as pulmonary rehabilitation, are highly effective to manage chronic lung disease. The outcomes of these interventions for Indigenous people require evaluation. The aim of this review was to critically appraise the literature on the impact of exercise-based interventions on quality of life, exercise capacity and health care utilisation in Indigenous adults with chronic lung disease in Australia, New Zealand, Canada, and USA. The Cochrane Library, Medline, Embase, CINAHL, Scopus, Psychinfo, APAIS-Aboriginal Health and PEDro databases were searched for peer-reviewed and grey literature that evaluated exercise-based interventions, such as pulmonary rehabilitation for Indigenous adults with chronic lung disease in Australia, New Zealand, Canada, and USA. Two authors independently screened and reviewed titles and abstract and full texts of potentially eligible studies for inclusion. An Indigenous decolonisation methodological framework was also applied to evaluate Indigenous governance, involvement, and engagement in the studies. A total of 3,598 records were screened, nine full papers were reviewed, and one was study included, which was a cardiopulmonary rehabilitation program for Indigenous people in Australia. Participants with chronic respiratory or heart disease significantly improved functional exercise capacity and quality of life [six-minute walk distance mean change (95% CI) 79 metres (47 to 111); Chronic Respiratory Questionnaire Dyspnoea 0.9 points (0.2 to 1.5)]. Several items of the decolonisation framework were addressed. Only one study was able to be included in the review, highlighting the paucity of research about culturally safe exercise-based interventions for Indigenous adults with chronic lung disease. There is a need for further research with strong Indigenous governance, involvement, and engagement.

Producing insecurity: Healthcare access, health insurance, and wellbeing among American Indian elders

Although health care is a treaty-guaranteed right for members of federally recognized tribes, decades of research describe persistent disparities in health and access to health services for American Indians. Despite gains in insurance enrollment after the passage of the 2010 Affordable Care Act, underfunding of the Indian Health Service and national debate over the new health law contributes to insecurity, especially among the majority of American Indians aged 55 and older who rely on public insurance. We consider the production of insecurity surrounding health care for American Indian elders, analyzing its pragmatic and affective consequences. Between June 2016 and March 2017, we conducted 96 quantitative surveys and in-depth qualitive interviews with American Indian elders aged 55 and older in two states in the U.S. Southwest. Interviews were recorded, professionally transcribed, and analyzed iteratively using open and focused coding. We found that elders consistently shared discourses of doubt, fear, and uncertainty that centered on: 1) interactions with healthcare providers and facilities, especially the IHS; 2) calculations regarding health insurance and the potential costs of healthcare services; and 3) dynamics at the national level around health policy, particularly for American Indians. We argue that persistent perceptions of healthcare insecurity present a major barrier to wellbeing that remains unaddressed by existing health policy interventions for this population, which focus predominately on individual-level knowledge and behavior.

Urban American Indian and Alaska Native Data Sovereignty: Ethical Issues

This paper examines the ethical issues underlying research with urban American Indians and Alaska Natives (AI/ANs) through the lens of tribal sovereignty. There are 574 federally recognized tribes within the United States. Each of those tribes is recognized by the federal government as having sovereign status, an important political designation that ensures that decisions impacting tribal peoples must be made after consultation with those nations. Most AI/AN people live away from their designated tribal lands, yet their sovereign rights are frequently only recognized when living on tribal lands. These urban AI/ANs are still considered citizens of their sovereign nations, yet they lack the protections afforded to those who live on tribal lands, including protections surrounding research with their tribal communities. We explore the Belmont Report and related documents and demonstrate their inadequacy in considering the cultural and ethical concerns specific to protecting urban AI/ANs. We also provide several solutions to help guide future institutional policies regarding research with urban AI/ANs that honors Indigenous data sovereignty, including consultation, partnership with community advisory boards, employment of data use agreements, and ensuring informed consent.

Systemic Disease and Ocular Comorbidity Analysis of Geographically Isolated Federally Recognized American Indian Tribes of the Intermountain West

BACKGROUND

The American Indian Navajo and Goshute peoples are underserved patient populations residing in the Four Corners area of the United States and Ibupah, Utah, respectively.

METHODS

We conducted a cross-sectional study of epidemiological factors and lipid biomarkers that may be associated with type II diabetes, hypertension and retinal manifestations in tribal and non-tribal members in the study areas (n = 146 participants). We performed multivariate analyses to determine which, if any, risk factors were unique at the tribal level. Fundus photos and epidemiological data through standardized questionnaires were collected. Blood samples were collected to analyze lipid biomarkers. Univariate analyses were conducted and statistically significant factors at p < 0.10 were entered into a multivariate regression.

RESULTS

Of 51 participants for whom phenotyping was available, from the Four Corners region, 31 had type II diabetes (DM), 26 had hypertension and 6 had diabetic retinopathy (DR). Of the 64 participants from Ibupah with phenotyping available, 20 had diabetes, 19 had hypertension and 6 had DR. Navajo participants were less likely to have any type of retinopathy as compared to Goshute participants (odds ratio (OR) = 0.059; 95% confidence interval (CI) = 0.016-0.223; p < 0.001). Associations were found between diabetes and hypertension in both populations. Older age was associated with hypertension in the Four Corners, and the Navajo that reside there on the reservation, but not within the Goshute and Ibupah populations. Combining both the Ibupah, Utah and Four Corners study populations, being American Indian (p = 0.022), residing in the Four Corners (p = 0.027) and having hypertension (p < 0.001) increased the risk of DM. DM (p < 0.001) and age (p = 0.002) were significantly associated with hypertension in both populations examined. When retinopathy was evaluated for both populations combined, hypertension (p = 0.037) and living in Ibupah (p < 0.001) were associated with greater risk of retinopathy. When combining both American Indian populations from the Four Corners and Ibupah, those with hypertension were more likely to have DM (p < 0.001). No lipid biomarkers were found to be significantly associated with any disease state.

CONCLUSIONS

We found different comorbid factors with retinal disease outcome between the two tribes that reside within the Intermountain West. This is indicated by the association of tribe and with the type of retinopathy outcome when we combined the populations of American Indians. Overall, the Navajo peoples and the Four Corners had a higher prevalence of chronic disease that included diabetes and hypertension than the Goshutes and Ibupah. To the best of our knowledge, this is the first study to conduct an analysis for disease outcomes exclusively including the Navajo and Goshute tribe of the Intermountain West.

Regional Differences In Coverage Among American Indians And Alaska Natives Before And After The ACA

Understanding regional variation in the effect of the Affordable Care Act (ACA) on health insurance coverage among vulnerable populations such as American Indian and Alaska Native adults has important policy implications. We used American Community Survey data for the period 2010-17 to examine unadjusted trends in health insurance coverage among American Indians and Alaska Natives across ten US regions. In each region we also used multivariate regression to evaluate the effects of the ACA on insurance coverage among American Indians and Alaska Natives and differences in effects between that group and non-Hispanic whites. In the West we observed significant improvements in public insurance among American Indians and Alaska Natives, and disparities compared to non-Hispanic whites were reduced following the ACA. Although there were unadjusted increases in insurance coverage across most regions, regression analyses suggested that there were no significant post-ACA changes in public or private health insurance coverage among American Indians and Alaska Natives in the Oklahoma, Bemidji, or Alaska regions. In sum, health insurance among American Indians and Alaska Natives increased after the ACA, but improvements were not consistent across regions. More attention is needed to improve insurance coverage among American Indians and Alaska Natives in midwestern regions.

Peripheral Artery Disease in Vulnerable Patient Populations: Outcomes of Orbital Atherectomy in Native Americans Compared to Non-Native Americans. A Single-Center Experience in Rural Oklahoma

BACKGROUND/PURPOSE

Although the incidence of peripheral artery disease (PAD) and amputations is higher in Native Americans (NA) than Caucasians, the study of revascularization NA is limited, resulting in their under representation in clinical studies. Orbital atherectomy (OA) is widely utilized for endovascular revascularization of significantly calcified peripheral arteries and has been shown to improve limb salvage rates.

METHODS/MATERIALS

A cohort of 74 consecutive PAD subjects undergoing OA treatment was retrospectively analyzed via Kaplan Meier (KM) and Propensity Score Matched (PSM) analysis.

RESULTS

A significant proportion of the subjects were NA (16.2%). Compared to the non-NA, the NA had higher numerical baseline rates of wounds, dialysis, chronic kidney disease (CKD), and critical limb ischemia, but were numerically less likely to smoke and had similar rates of diabetes. There were very high rates of severe calcification (100% vs. 87%) and pre-procedure diameter stenosis (99% vs. 95%) in both groups. The NA and non-NA had good angiographic outcomes, resulting in low rates of post-procedure residual diameter stenosis (10% vs. 11%). Lastly, KM analysis indicated high freedom from amputation in both groups at 1 year (89% vs. 95%), as well as in the PSM subjects (89% vs. 100%).

CONCLUSIONS

Despite numerically higher rates of co-morbidities at baseline (e.g., CKD, dialysis, and presence of non-healing wounds), the NA underwent successful revascularization with OA, resulting in high freedom from amputation at 1-year. Given the small sample size of NA, these results may not be generalizable-thus, larger studies on NA are warranted.

CYP2D6*10 pharmacogenetic-guided SERM could be a cost-effective strategy in Chinese patients with hormone receptor-positive breast cancer

Aim: To assess the cost-effectiveness of CYP2D6*10 genetic testing for the management of Chinese women with hormone receptor-positive (HR+) breast cancer treated with selective estrogen receptor modulator. Methods: A Markov model was developed to evaluate a total expected cost and an incremental cost-effectiveness ratio (ICER). Robustness of the model was addressed in one-way analyses and probabilistic sensitivity analysis. Results: The cost of strategies of tamoxifen, toremifene without genotyping and the strategy base on CYP2D6*10 genotype were $63,879.19, $90,156.60 and $95,021.41, and the quality-adjusted life years gained are 8.1588, 12.89687 and 13.85911, respectively. The incremental cost-effectiveness ratio of the CYP2D6*10 testing versus toremifene were 5,055.74221/quality-adjusted life year, respectively. Conclusion: CYP2D6*10 pharmacogenetic-guided selective estrogen receptor modulator can be a cost-effective strategy in the Chinese patients with hormone receptor-positive breast cancer.

Ethnic inequality within the elderly population in utilizing healthcare services

The accessibility of minority ethnic groups to healthcare services is challenging in many societies, most especially among the elderly population. Elderly individuals from minority groups have been found to have lower levels of utilizing healthcare services, including preventive care, intensive hospital care, advanced technological procedures and rehabilitation. Universal health coverage is incapable of addressing all of healthcare's access inequities and there is a need to assess the overall outcomes, including mortality rates over time, functionality of discharged patients, quality of life and/or unplanned readmissions that may indicate low quality hospital discharge processes. There is a need to investigate the impact of perceived trust/distrust in the healthcare system of elderly patients from minority ethnicities on their willingness to consume medical services.To ensure equity in service provision, there is a need to examine whether medical providers, even unconsciously, prioritize vital services, such as rehabilitation services to populations that share similar social backgrounds. An essential measure is enhancement of health literacy at all levels, from the individual to policy-makers and strategic adoption of health literacy programs that encompass all ethnicities, considering their respective needs, norms and expectations.Ethnic equality in accessing medical services is crucial in view of the numerous migrants and asylum-seekers who look for refuge in varied societies globally. Such populations are perceived as faring worse in healthcare quality of care, and this highlights the need to adapt the healthcare systems to the varied health behaviors, contextual factors, language barriers, lower health literacy levels and limited access to timely care. Improving equity and access to medical care is dependent on enhanced health literacy; policies that consider diverse needs of majority and minority groups; and advanced research. Concurrent implementation of these measures will be well aligned with the global strive to promote the Sustainable Development Goals (SDGs).
