Barriers to Healthcare for American Indians Experiencing Homelessness

Integrated Response to Address a Resurgent Syphilis Epidemic in a Rural American Indian Community, Whiteriver, Arizona, January 2022 to June 2023

BACKGROUND

The United States has seen a significant rise in syphilis over the past 20 years with a disparate impact on American Indian communities. We conducted a thorough review of the local epidemiology that guided an innovative response to curb the epidemic.

METHODS

We analyzed syphilis data from a hospital in rural Arizona that serves an American Indian population of more than 18,000. Testing data were extracted from 2017 to 2023 with detailed chart reviews of all reactive results since January 2022. Descriptive and comparative statistics were computed using parametric and nonparametric methods where appropriate.

RESULTS

Among 5888 tested persons, 555 (9.4%) had reactive results and 277 (4.7%) represented new infections. Among new cases, 151 (54.5%) were female and 55 (19.9%) were reinfections. The annualized incidence rate was 10.0 cases per 1000 persons with peak annualized incidence among women aged 30 to 34 years of 22.6 infections per 1000 persons. During the observation period and after the implementation of programmatic changes in June 2022, there were statistically significant reductions in median time to treatment (-80%), test positivity (-70%), infections (-60%), and no congenital syphilis cases during the observation period.

CONCLUSIONS

We observed significantly elevated syphilis rates in American Indian/Alaska Native persons compared with the general population. Strategic implementation of new policies and practices led to a measurable and meaningful improvement in several epidemic variables, and our experience may serve as a model to other communities.

Race and ethnicity in the COVID-19 Critical Care Consortium: demographics, treatments, and outcomes, an international observational registry study

BACKGROUND

Improving access to healthcare for ethnic minorities is a public health priority in many countries, yet little is known about how to incorporate information on race, ethnicity, and related social determinants of health into large international studies. Most studies of differences in treatments and outcomes of COVID-19 associated with race and ethnicity are from single cities or countries.

METHODS

We present the breadth of race and ethnicity reported for patients in the COVID-19 Critical Care Consortium, an international observational cohort study from 380 sites across 32 countries. Patients from the United States, Australia, and South Africa were the focus of an analysis of treatments and in-hospital mortality stratified by race and ethnicity. Inclusion criteria were admission to intensive care for acute COVID-19 between January 14th, 2020, and February 15, 2022. Measurements included demographics, comorbidities, disease severity scores, treatments for organ failure, and in-hospital mortality.

RESULTS

Seven thousand three hundred ninety-four adults met the inclusion criteria. There was a wide variety of race and ethnicity designations. In the US, American Indian or Alaska Natives frequently received dialysis and mechanical ventilation and had the highest mortality. In Australia, organ failure scores were highest for Aboriginal/First Nations persons. The South Africa cohort ethnicities were predominantly Black African (50%) and Coloured* (28%). All patients in the South Africa cohort required mechanical ventilation. Mortality was highest for South Africa (68%), lowest for Australia (15%), and 30% in the US.

CONCLUSIONS

Disease severity was higher for Indigenous ethnicity groups in the US and Australia than for other ethnicities. Race and ethnicity groups with longstanding healthcare disparities were found to have high acuity from COVID-19 and high mortality. Because there is no global system of race and ethnicity classification, researchers designing case report forms for international studies should consider including related information, such as socioeconomic status or migration background. *Note: "Coloured" is an official, contemporary government census category of South Africa and is a term of self-identification of race and ethnicity of many citizens of South Africa.

An Updated Narrative Review on the Role of Alcohol Among Indigenous Communities

Purpose of Review

The role of alcohol varies considerably among Indigenous Peoples and is the backdrop of persistent stereotypes despite decades of research. This paper provides an updated narrative review on the alcohol literature among Indigenous communities, highlighting recent studies published since 2017.

Recent Findings

We examined published literature involving alcohol use rates, including abstinence; risk and protective factors; treatment; and recovery, as well as future directions for alcohol prevention and intervention efforts with Indigenous communities.

Summary

Evidence-based alcohol use prevention, intervention, and recovery strategies with Indigenous communities are outlined. Recommendations are provided for researchers, health providers, and public policy advocates to address and better understand alcohol use, treatment, prevention, and recovery among Indigenous Peoples. Specific recommendations include using community-based participatory research strategies and harm reduction approaches to prevent and treat alcohol use problems with Indigenous communities. Future research is needed to elucidate mechanisms of resilience and recovery from Alcohol Use Disorder and possible shifts in perceptions of alcohol use for Indigenous Peoples.

Race matters in addressing homelessness: A scoping review and call for critical research

Structural racism contributes to homelessness in the United States, as evidenced by the stark racial disparities in who experiences it. This paper reviews research at the intersections of race and homelessness to advance efforts to understand and address racial inequities. Part 1 offers a synthesis of homelessness research from the 1980s to 2015, where several scholars examined the role of race and racism despite mainstream efforts to present the issue as race-neutral. Part 2 presents the results of a systematic scoping review of research at the intersections of race and homelessness from 2016 to 2021. The 90 articles included demonstrate a growing, multidisciplinary body of literature that documents how needs and trajectories of people experiencing homelessness differ by race, examines how the racialized structuring of society contributes to homelessness risk, and explores how programs, policies, and grassroots action can address inequities. In addition to charting findings and implications, included studies are appraised against research principles developed by Critical Race Theory scholars, mapping the potential of existing research on race and homelessness to challenge racism.

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.

Health Care Utilization among Homeless-Experienced Adults Who Were Seen by a Mobile Addiction Health Clinic in Boston, Massachusetts: A Quasi-Experimental Study

Background: Mobile health clinics improve access to care for marginalized individuals who are disengaged from the healthcare system. This study evaluated the association between a mobile addiction health clinic and health care utilization among people experiencing homelessness. Methods: Using Medicaid claims data, we evaluated adults who were seen by a mobile addiction health clinic in Boston, Massachusetts from 1/16/18-1/15/19 relative to a propensity score matched control cohort. We evaluated both cohorts from four years before to one year after the index visit date with the mobile clinic. The primary outcome was the number of outpatient visits; secondary outcomes were the number of hospitalizations and emergency department (ED) visits. We used Poisson regression to compare changes in outcomes from before to after the index date in a quasi-experimental design. Results: 138 adults were seen by the mobile clinic during the observation period; 29.7% were female, 16.7% were Black, 8.0% Hispanic, 68.1% White, and the mean age was 40.4 years. The mean number of mobile clinic encounters was 3.1. The yearly mean number of outpatient visits increased from 11.5 to 12.1 (p = 0.43; pdiff-in-diff = 0.15), the number of hospitalizations increased from 2.2 to 3.0 (p = 0.04; pdiff-in-diff = 0.87), and the number of ED visits increased from 5.4 to 6.5 (p = 0.04; pdiff-in-diff = 0.40). Conclusions: The mobile addiction health clinic was not associated with statistically significant changes in health care utilization in the first year. Further research in larger samples using a broader set of outcomes is needed to quantify the benefits of this innovative care delivery model.

Results from a test-and-treat study for influenza among residents of homeless shelters in King County, WA: A stepped-wedge cluster-randomized trial

BACKGROUND

Persons experiencing homelessness face increased risk of influenza as overcrowding in congregate shelters can facilitate influenza virus spread. Data regarding on-site influenza testing and antiviral treatment within homeless shelters remain limited.

METHODS

We conducted a cluster-randomized stepped-wedge trial of point-of-care molecular influenza testing coupled with antiviral treatment with baloxavir or oseltamivir in residents of 14 homeless shelters in Seattle, WA, USA. Residents ≥3 months with cough or ≥2 acute respiratory illness (ARI) symptoms and onset <7 days were eligible. In control periods, mid-nasal swabs were tested for influenza by reverse transcription polymerase chain reaction (RT-PCR). The intervention period included on-site rapid molecular influenza testing and antiviral treatment for influenza-positives if symptom onset was <48 h. The primary endpoint was monthly influenza virus infections in the control versus intervention periods. Influenza whole genome sequencing was performed to assess transmission and antiviral resistance.

RESULTS

During 11/15/2019-4/30/2020 and 11/2/2020-4/30/2021, 1283 ARI encounters from 668 participants were observed. Influenza virus was detected in 51 (4%) specimens using RT-PCR (A = 14; B = 37); 21 influenza virus infections were detected from 269 (8%) intervention-eligible encounters by rapid molecular testing and received antiviral treatment. Thirty-seven percent of ARI-participant encounters reported symptom onset < 48 h. The intervention had no effect on influenza virus transmission (adjusted relative risk 1.73, 95% confidence interval [CI] 0.50-6.00). Of 23 influenza genomes, 86% of A(H1N1)pdm09 and 81% of B/Victoria sequences were closely related.

CONCLUSION

Our findings suggest feasibility of influenza test-and-treat strategies in shelters. Additional studies would help discern an intervention effect during periods of increased influenza activity.

Artificial intelligence and machine learning in precision medicine: A paradigm shift in big data analysis

The integration of artificial intelligence in precision medicine has revolutionized healthcare delivery. Precision medicine identifies the phenotype of particular patients with less-common responses to treatment. Recent studies have demonstrated that translational research exploring the convergence between artificial intelligence and precision medicine will help solve the most difficult challenges facing precision medicine. Here, we discuss different aspects of artificial intelligence in precision medicine that improve healthcare delivery. First, we discuss how artificial intelligence changes the landscape of precision medicine and the evolution of artificial intelligence in precision medicine. Second, we highlight the synergies between artificial intelligence and precision medicine and promises of artificial intelligence and precision medicine in healthcare delivery. Third, we briefly explain the promise of big data analytics and the integration of nanomaterials in precision medicine. Last, we highlight the challenges and opportunities of artificial intelligence in precision medicine.

The Health Needs of Regionally Based Individuals Who Experience Homelessness: Perspectives of Service Providers

The bidirectional relationship between homelessness and poor health and the barriers that individuals who experience homelessness face when trying to access healthcare are well documented. There is, however, little Australian research exploring the situation of individuals who experience homelessness in regional contexts and, moreover, from the perspective of service providers. A qualitative descriptive methodology underpinned this study, with in-depth semi-structured interviews being conducted with 11 service providers to identify barriers to care faced by people who experience homelessness and barriers that service providers themselves experience in supporting this population. The key barriers identified were client-level barriers: living day-by-day, financial, health literacy, mental health conditions, behaviour, safety and stigma; provider-level barriers: few bulk-billing doctors, fragmented services, limited resources, negative past experiences with healthcare; and system level barriers: transportation, over-stretched healthcare services. The combined impact of these barriers has significantly contributed to the desperate situation of people experiencing homelessness in Launceston. This situation is likely replicated in other regional populations in Australia. Given that individuals experiencing homelessness have higher rates of every measure in health inequality, steps need to be taken to reduce barriers, and a standardised approach to health care urgently needs to be implemented by governments at the state and national level to improve the health of regionally based individuals experiencing homelessness.

Emergency Department Use by Women Experiencing Homelessness in Los Angeles, California, USA

Background:

This article reports on the use of hospital Emergency Departments (EDs) in women experiencing homelessness in Los Angeles, California. Women 18 years of age or older were recruited from homeless day centers in Los Angeles to participate in this study.

Materials and Methods:

A self-report questionnaire on health status, demographics, and emergency service use was completed by study participants.

Results:

In this study of women experiencing homelessness, 64% utilized the ED within the past year. The mean number of ED use was 3.63 (range 0–20) visits in the past year. Higher frequency visits were significantly associated with several mental health conditions (p = 0.016), physical disability (p = 0.001), and traumatic brain injury (p = 0.013).

Conclusions:

The physical and psychological impacts of the homelessness experience can be enormous, affecting the homeless individually and collectively. Study findings may help to understand how to improve services that support and meet the needs of women experiencing homelessness such as patient and family-centered care and trauma-informed care in the ED.

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.

Substance use disorder and homelessness among American Indians and Alaska Natives in California

American Indian and Alaska Native (AIAN) communities have higher rates of substance use than other racial and ethnic groups. Substance use disorder (SUD) is tied to the increased risk of experiencing homelessness. National policies have also led to the disproportionate rates of homelessness among AIAN communities. However, specific experiences related to the occurrence of SUD and homelessness among AIAN in California, as well as seeking and accessing SUD treatment, are not well understood. This study explored potential SUD risk and resilience factors for AIANs experiencing homelessness and their experiences when seeking services for SUD. Nineteen interviews were conducted in northern, central, and southern California. Thematic analysis was used for these data. The five primary codes were: (1) risk factors for SUD, (2) resilience related to SUD service seeking, (3) services available, (4) barriers accessing services, and (5) services needed. Based on the results, themes for risk were trauma, mental health, and community conditions. Themes for resilience were identified at individual and community levels and included personal motivation and community support and inclusiveness. Themes for services available were limited knowledge about service types and services' location. The themes for barriers accessing services were identified at internal and external levels, and included lack of readiness and transportation challenges, respectively. Themes for services needed included continuum of care, integrated care, and culturally sensitive services. Findings highlight the importance of addressing the potential risk factors and service needs of AIANs experiencing homelessness to provide comprehensive and culturally sensitive services to reduce substance use.

Tuberculosis Genotype Clusters and Transmission in the U.S., 2009-2018

INTRODUCTION

In the U.S., universal genotyping of culture-confirmed tuberculosis cases facilitates cluster detection. Early recognition of the small clusters more likely to become outbreaks can help prioritize public health resources for immediate interventions.

METHODS

This study used national surveillance data reported during 2009-2018 to describe incident clusters (≥3 tuberculosis cases with matching genotypes not previously reported in the same county); data were analyzed during 2020. Cox proportional hazards regression models were used to examine the patient characteristics associated with clusters doubling in size to ≥6 cases.

RESULTS

During 2009-2018, a total of 1,516 incident clusters (comprising 6,577 cases) occurred in 47 U.S. states; 231 clusters had ≥6 cases. Clusters of ≥6 cases disproportionately included patients who used substances, who had recently experienced homelessness, who were incarcerated, who were U.S. born, or who self-identified as being of American Indian or Alaska Native race or of Black race. A median of 54 months elapsed between the first and the third cases in clusters that remained at 3-5 cases compared with a median of 9.5 months in clusters that grew to ≥6 cases. The longer time between the first and third cases and the presence of ≥1 patient aged ≥65 years among the first 3 cases predicted a lower hazard for accumulating ≥6 cases.

CONCLUSIONS

Clusters accumulating ≥3 cases within a year should be prioritized for intervention. Effective response strategies should include plans for targeted outreach to U.S.-born individuals, incarcerated people, those experiencing homelessness, people using substances, and individuals self-identifying as being of American Indian or Alaska Native race or of Black race.

Understanding measures of racial discrimination and microaggressions among American Indian and Alaska Native college students in the Southwest United States

BACKGROUND

Racial discrimination, including microaggressions, contributes to health inequities, yet research on discrimination and microaggressions has focused on single measures without adequate psychometric evaluation. To address this gap, we examined the psychometric performance of three discrimination/microaggression measures among American Indian and Alaska Native (AI/AN) college students in a large Southwestern city.

METHODS

Students (N = 347; 65% female; ages 18-65) completed the revised-Everyday Discrimination Scale, Microaggressions Distress Scale, and Experiences of Discrimination measure. The psychometric performance of these measures was evaluated using item response theory and confirmatory factor analyses. Associations of these measures with age, gender, household income, substance use, and self-rated physical health were examined.

RESULTS

Discrimination and microaggression items varied from infrequently to almost universally endorsed and each measure was unidimensional and moderately correlated with the other two measures. Most items contributed information about the overall severity of discrimination and collectively provided information across a continuum from everyday microaggressions to physical assault. Greater exposure to discrimination on each measure had small but significant associations with more substance use, lower income, and poorer self-rated physical health. The Experiences of Discrimination measure included more severe forms of discrimination, while the revised-Everyday Discrimination Scale and the Microaggressions Distress Scale represented a wider range of severity.

CONCLUSIONS

In clinical practice, these measures can index varying levels of discrimination for AI/ANs, particularly for those in higher educational settings. This study also informs the measurement of racial discrimination and microaggressions more broadly.

Health Risk Factors in American Indian and Non-Hispanic White Homeless Adults

Objectives: American Indians (AIs) are over-represented among homeless populations, but are understudied regarding their unique risk and resilience factors relative to non-Hispanic white (NHW) adults experiencing homelessness. In the current study, we aimed to address this gap. Methods: We recruited participants (108 AIs and 307 NHWs) from 6 homeless serving agencies in Oklahoma City, OK. Participants completed standard assessments of health, health behaviors, including alcohol and drug use, readiness to change endorsed health behaviors (eg, unsafe sex, fruit and vegetable intake, happiness with weight, physical activity), sleep location and quality, personal victimization, and discrimination. Results: Compared to NHWs, AIs endorsed greater alcohol use problems and were more likely to report having been arrested/booked for disorderly conduct or public drunkenness; however, AIs were less likely to report smoking cigarettes and reported greater readiness to change unsafe/unprotected sexual behaviors. Furthermore, compared to NHWs, AIs reported experiencing greater discrimination and were more likely to report sleeping outside or on the streets, versus in shelters; however, AIs reported fewer days of inadequate sleep. Conclusions: Findings suggest AI-specific risk and resilience factors for homelessness. This information can aid in treatment, service, and housing planning for this under-studied group who experiences some of the greatest health disparities.

Sources of Stress Among Midwest American Indian Adults with Type 2 Diabetes

Despite alarming health disparities among American Indians (AIs) and acknowledgement that stressors negatively influence health, conceptualization of the full spectrum of stressors that impact Indigenous communities is underdeveloped. To address this gap, we analyze focus group transcripts of AI adults with type 2 diabetes from five tribal communities and classify stressors using an inductive/deductive analytical approach. A Continuum of American Indian Stressor Model was constructed from categorization of nineteen stressor categories within four domains. We further identified poverty, genocide, and colonization as fundamental causes of contemporary stress and health outcomes for AIs and conclude that stressors are generally experienced as chronic, regardless of the duration of the stressor. This work on AI-specific stressors informs future health research on the stress burden in AI communities and identifies target points for intervention and health promotion.
