Hemodialysis Disparities in African Americans: The Deeply Integrated Concept of Race in the Social Fabric of Our Society

End‐stage renal disease (ESRD) is one of the starkest examples of racial/ethnic disparities in health. Racial/ethnic minorities are 1.5 to nearly 4 times more likely than their non‐Hispanic White counterparts to require renal replacement therapy (RRT), with African Americans suffering from the highest rates of ESRD. Despite improvements over the last 25 years, substantial racial differences are persistent in dialysis quality measures such as RRT modality options, dialysis adequacy, anemia, mineral and bone disease, vascular access, and pre‐ESRD care. This report will outline the current status of racial disparities in key ESRD quality measures and explore the impact of race. While the term race represents a social construct, its association with health is more complex. Multiple individual and community level social determinants of health are defined by the social positioning of race in the U.S., while biologic differences may reflect distinct epigenetic changes and linkages to ancestral geographic origins. Together, these factors conspire to influence dialysis outcomes among African Americans with ESRD.     

COVID‐19 pandemic and health care disparities in head and neck cancer: Scanning the horizon

The COVID‐19 pandemic has profoundly disrupted head and neck cancer (HNC) care delivery in ways that will likely persist long term. As we scan the horizon, this crisis has the potential to amplify preexisting racial/ethnic disparities for patients with HNC. Potential drivers of disparate HNC survival resulting from the pandemic include (a) differential access to telemedicine, timely diagnosis, and treatment; (b) implicit bias in initiatives to triage, prioritize, and schedule HNC‐directed therapy; and (c) the marked changes in employment, health insurance, and dependent care. We present four strategies to mitigate these disparities: (a) collect detailed data on access to care by race/ethnicity, income, education, and community; (b) raise awareness of HNC disparities; (c) engage stakeholders in developing culturally appropriate solutions; and (d) ensure that surgical prioritization protocols minimize risk of racial/ethnic bias. Collectively, these measures address social determinants of health and the moral imperative to provide equitable, high‐quality HNC care.     

Racial and Ethnic Healthcare Disparities in Skin Cancer in the United States: A Review of Existing Inequities,Contributing Factors,and Potential Solutions

Objective Racial and ethnic health disparities affect the diagnosis and management of melanoma and nonmelanoma skin cancers, leading to deleterious outcomes. Non-Hispanic White patients make up the majority of skin cancers cases, yet racial and ethnic minorities have poorer prognoses and outcomes. The skin cancer literature is fragmented with regards to potential contributors to these healthcare disparities. In this article, we provide a comprehensive review of the skin cancer literature to briefly quantify racial and ethnic inequities, highlight contributing factors, and propose practical changes that can be made.MethodsA PubMed search was completed to identify articles related to racial and ethnic health care disparities in the context of melanoma, basal cell carcinoma, squamous cell carcinoma, Merkel cell carcinoma, and dermatofibrosarcoma protuberans.ResultsRelative to non-Hispanic White patients, patients of racial and ethnic minorities have differing clinical presentations of skin cancers and genetic risk factors. Insurance, access to specialty care, cultural beliefs, and available educational resources further contribute to racial and ethnic disparities.LimitationsWe are limited to the level of detail provided in the existing literature, and at some times are unable to distinguish race of Hispanic populations. We also acknowledge that there are different nationalities grouped under these broad labels as well as multi-racial populations that may not be accounted for.ConclusionAwareness of and familiarization with innate factors and potentially more modifiable contributors can help inform efforts to close the observed gap in racial and ethnic inequities.     

Effects of Health Disparities on Survival after Neonatal Heart Surgery: Why Should Racial,Ethnic, Gender,and Socioeconomic Status Be Included in the Risk Analysis?

Health disparities are "differences in the quality of health and health care across different populations." Potential disparities associated with race, ethnicity, gender, and socioeconomic status should be considered when attempting to develop models for survival and neurodevelopmental outcomes in neonates undergoing congenital heart surgery. Each of the aforementioned sociodemographic factors is related to postsurgical mortality because they are frequently linked to measures of access to care in addition to location of care (geographically) and the type of institution (teaching vs. nonteaching) where patients receive care. Traditionally these factors have not been considered in models of surgical treatment outcomes in conditions such as hypoplastic left heart syndrome. However, we believe these factors should at least be included in risk analysis models to help explain their impact on outcomes and in predicting outcomes. Therefore, the purpose of this article is to highlight some of the nonsurgical influences that affect survival after neonatal heart surgery such as race, ethnicity, gender, and socioeconomic status.     

Race and Ethnicity in Access to and Outcomes of Liver Transplantation: A Critical Literature Review

Racial/ethnic disparities in access to and outcomes of liver transplantation are an important topic given the increasing diversity in the United States. Most reports on this topic predate the advent of allocation based on the model for end‐stage liver disease (MELD). For many patients with a variety of lethal conditions, liver transplantation is the only effective therapy, signifying the importance of equitable access to care. Racial/ethnic disparities have been described at various steps of the liver transplant process, including liver disease prevalence and treatment, access to a transplant center and its waitlist, receipt of a liver transplant and posttransplant outcomes. The purpose of this minireview is to critically evaluate the published literature on racial/ethnicity‐based disparities in liver disease prevalence and treatment, transplant center referral, transplant rates and posttransplant outcomes. We identify the shortcomings of previous reports and detail the barriers to completing properly constructed analyses, particularly emphasizing deficits in requisite data and the need for improved study design. Understanding the nature of race/ethnicity‐based disparities in liver transplantation is necessary to improve research initiatives, policy design and serves the broader responsibility of providing the highest quality care to all patients with liver disease.     

The relation between satisfaction with appearance and race and ethnicity: A National Institute on Disability,Independent Living,and Rehabilitation Research burn model system study

Research supports that people of color in the U.S. have poorer outcomes after burn injury compared to White individuals. The current study sought to explore burn health disparities by testing the relationship between racial and ethnic minority status, a proxy for systemic discrimination due to race and ethnicity, with two key constructs linked to functional outcomes, satisfaction with appearance and social community integration. Participants included 1318 burn survivors from the Burn Model System National Database (mean age = 40.2, SD = 12.7). Participants completed measures of satisfaction with appearance and social community integration at baseline, 6-, 12-, and 24-months after burn injury. Linear regressions revealed that racial and ethnic minority status significantly related to lower satisfaction with appearance and social community integration compared to White individuals at all time points. In addition, satisfaction with appearance continued to significantly relate to greater social community integration even while accounting for race and ethnicity, age, sex, burn size, and physical disability at 6-, 12-, and 24-month time points. Overall, the study supports that racial and ethnic minority burn survivors report greater dissatisfaction with their appearance and lower social community reintegration after burn injury.     

Caring for Diverse and High-Risk Patients: Surgeon,Health System,and Patient Integration

Access and outcome disparities exist in hip and knee arthroplasty care. These disparities are associated with race, ethnicity, and social determinants of health such as income, housing, transportation, education, language, and health literacy. Additionally, medical comorbidities affecting postoperative outcomes are more prevalent in underresourced communities, which are more commonly communities of color.Navigating racial and ethnic differences in treating our patients undergoing hip and knee arthroplasty is necessary to reduce inequitable care. It is important to recognize our implicit biases and lessen their influence on our healthcare decision-making. Social determinants of health need to be addressed on a large scale as the current inequitable system disproportionally impacts communities of color.Patients with lower health literacy have a higher risk of postoperative complications and poor outcomes after hip and knee replacement. Low health literacy can be addressed by improving communication, reducing barriers to care, and supporting patients in their efforts to improve their own health.High-risk patients require more financial, physical, and mental resources to care for them, and hospitals, surgeons, and health insurance companies are often disincentivized to do so. By advocating for alternative payment models that adjust for the increased risk and take into account the increased perioperative work needed to care for these patients, surgeons can help reduce inequities in access to care.We have a responsibility to our patients to recognize and address social determinants of health, improve the diversity of our workforce, and advocate for improved access to care to decrease inequity and outcomes disparities in our field.     

Risk Adjustment and the Assessment of Disparities in Dialysis Mortality Outcomes

Standardized mortality ratios (SMRs) reported by Medicare compare mortality at individual dialysis facilities with the national average, and are currently adjusted for race. However, whether the adjustment for race obscures or clarifies disparities in quality of care for minority groups is unknown. Cox model-based SMRs were computed with and without adjustment for patient race for 5920 facilities in the United States during 2010. The study population included virtually all patients treated with dialysis during this period. Without race adjustment, facilities with higher proportions of black patients had better survival outcomes; facilities with the highest percentage of black patients (top 10%) had overall mortality rates approximately 7% lower than expected. After adjusting for within-facility racial differences, facilities with higher proportions of black patients had poorer survival outcomes among black and non-black patients; facilities with the highest percentage of black patients (top 10%) had mortality rates approximately 6% worse than expected. In conclusion, accounting for within-facility racial differences in the computation of SMR helps to clarify disparities in quality of health care among patients with ESRD. The adjustment that accommodates within-facility comparisons is key, because it could also clarify relationships between patient characteristics and health care provider outcomes in other settings.     

Racial disparities in health outcomes after spinal cord injury: mediating effects of education and income

OBJECTIVE: The purpose of this study was to investigate heath disparities as a function of race and gender and the extent to which socioeconomic factors mediate disparities among participants with spinal cord injury. DESIGN: Survey methodology. Cross-sectional data. SETTING: A large Southeastern specialty hospital. PARTICIPANTS: There were 1342 participants in the current analysis, all of whom were identified from patient records. There were 3 inclusion criteria: (a) traumatic SCI, (b) at least 18 years of age at the time of study, and (c) injury duration of more than 1 year. MAIN OUTCOME MEASURES: Six outcomes were measured, including 3 general outcomes (self-ratings, days impacted by poor health, days impacted by poor mental health) and 3 that reflect utilization of services (hospitalizations, days hospitalized, and nonroutine physician visits in the past 2 years). Results: Results of multivariate analysis of variance (MANOVA) indicated significant main effects for both race and gender. Follow-up tests identified racial disparities on 3 of the 6 outcomes, whereas gender disparities were observed for a single outcome. Years of education and household income mediated interrelationships between race and health (but not gender) as racial disparities disappeared after consideration of these factors. CONCLUSIONS: These findings suggest the need to work more diligently to promote better health outcomes among African Americans and to further investigate how socioeconomic factors and access to health care related to diminished health outcomes among African Americans with spinal cord injury.     

Disparities in surgical health service delivery and outcomes for indigenous children

BackgroundEvidence of health disparities for Indigenous children requiring surgical care is lacking. We present a systematic review of the literature examining possible disparities in surgical care and outcomes for pediatric patients of Indigenous ethnicity.Data sourcesPubMed, Cochrane, MEDLINE, gray literature.MethodsLiterature review, using PubMed, Cochrane, MEDLINE, and gray literature was conducted to identify articles published more than 2010–2020 examining children's surgical health service delivery (epidemiology, access, operations provided) and outcomes for pediatric patients of Indigenous ethnicity compared with others. Extracted data included study design, setting, participant race/ethnicity, operations examined, and surgical outcomes. Article quality was assessed using the Newcastle-Ottawa Scales.ResultsFrom 411 abstracts, 125 articles were reviewed and 33 included for data abstraction. These were cohort and cross-sectional studies investigating a wide range of patient populations and procedures across the United States, Canada, Australia, and New Zealand. Articles were organized naturally by theme into birth malformations (15 articles), trauma (6 articles), pediatric general surgery/appendicitis (5 articles), pediatric otolaryngology (6 articles), and renal transplant (1 article) surgery. Four articles also described access and resource utilization related to inpatient care. Notable disparities observed included apparent increased prevalence of gastroschisis, rates of traumatic fatality, non accidental injury, and self harm among North American Indigenous children.ConclusionsIndigenous children appear to be vulnerable to a number of health and treatment outcome disparities related to conditions treated by surgeons. Surgeons are thus uniquely poised to act in identifying and eliminating Indigenous ethnicity-based pediatric health disparities.     

Racial and Ethnic Differences in the Use of Regional Anesthesia for Patients Undergoing Total Knee Arthroplasty

BackgroundThere is an increasing body of evidence that suggests racial and ethnic disparities exist in medical care. In the field of anesthesiology, few studies have investigated the association of race and ethnicity with the provision of regional anesthesia for patients undergoing total knee arthroplasty. This analysis queried a large national surgical database to determine whether there were racial or ethnic differences in the administration of peripheral nerve blocks for patients undergoing total knee arthroplasty.MethodsIn this retrospective cohort study, data were collected from a large national database during the years 2017-2019. Multivariable logistic regressions were used to measure the association of race and ethnicity with utilization of regional anesthesia. The participants for the study were patients 18 years or older undergoing total knee arthroplasty.ResultsOur primary finding was that among patients undergoing total knee arthroplasty, Black patients had lower odds (adjusted odds ratio [aOR]: 0.93, 99% confidence interval [CI]: 0.89-0.98) of receiving regional anesthesia than White patients. Also, Hispanic patients had lower odds (aOR: 0.88, 99% CI: 0.83-0.94) of receiving regional anesthesia than non-Hispanic patients. Native Hawaiian/Pacific Islander patients had increased odds (aOR: 2.04, 99% CI: 1.66-2.51) of receiving regional anesthesia.ConclusionThis study demonstrated that there might be racial and ethnic differences in the provision of regional anesthesia for patients undergoing total knee arthroplasty. These differences underscore the need for more studies aimed at equitable access to high quality and culturally competent health care.     

Racial and Ethnic Disparities in Short-Stay Total Knee Arthroplasty

BackgroundThe purpose of this study was to understand racial and ethnic disparities in hospital-based, Medicare-defined outpatient total knee arthroplasty (TKA). We aimed to determine the following: 1) whether there are differences in preoperative characteristics or postoperative outcomes in outpatient TKA between racial/ethnic groups and 2) trends in outpatient TKA volume, based on race/ethnicity.MethodsThis was a retrospective cohort study of a large national database. Outpatient TKAs performed between 2012 and 2018 were identified. Patient demographics, comorbidities, and 30-day postoperative outcomes were compared between White, Black, Asian, and Hispanic patients.ResultsOf 54,183 outpatient patients, 85.6% were White, 7.4% Black, 2.6% Asian, and 4.1% Hispanic. Black patients had the highest body mass index, and there were higher rates of diabetes among all minority groups (P < .001). All minority groups were more likely to be discharged to a rehabilitation or a skilled care facility compared to White patients (P < .001). Annual percentage increases in outpatient TKA were most pronounced for Asians and Hispanics and least pronounced among Blacks, when compared to White patients.ConclusionThe outcomes of outpatient TKA are impacted by risk factors that reflect underlying disparities in healthcare. As joint arthroplasties have come off the inpatient-only list and procedures move to ambulatory settings, these disparities will likely magnify and impact outcomes, costs, and access points. Extensive preoperative optimization and interventions that target medical and social factors may help to reduce these disparities in TKA and increase access among minority patients.Level of EvidenceIII, retrospective cohort study.     

Urologic oncology workforce diversity: A first step in reducing cancer disparities

Urologic cancer disparities based on race/ethnicity and gender are well-documented across the cancer continuum. Patients cared for by physicians of similar race/ethnicity and gender report better communication, patient satisfaction, and care adherence which has the potential to translate into better health outcomes. We believe that ensuring a diverse Urologic Oncology workforce is an important first step toward eliminating cancer disparities due to the downstream effects of improved communication between concordant patient–physician dyads. In this essay, we review the demographics of the Urologic cancer patient population and Urologic Oncology workforce; describe current evidence supporting healthcare workforce diversity, especially related to race and gender-based concordant patient–physician relationships; and make recommendations for individual and institutional strategies to develop and support a diverse workforce in Urologic Oncology.     

Ethical implications of ethnic disparities in chronic kidney disease and kidney transplantation

Chronic kidney disease (CKD) is a major epidemic in underserved and minority populations largely due to excess rates of hypertensive and diabetic kidney disease. Multiple complex socioeconomic barriers to early diagnosis and optimal therapies as well as delayed referral for kidney transplantation have created disparities in CKD care provided to ethnic minorities. Disparities exist in wait list time and kidney transplant rates for Native Americans and blacks, independent of insurance status. Moreover, independent of genetic matching, long-term transplant outcomes in blacks remain significantly lower than all other ethnic groups, suggesting that poorly understood social factors contribute to these survival differences. The existence of these disparities raises ethical concerns of equity and social justice in terms of the allocation of scarce resources. Although current changes in allocation policies will improve some disparities, more efforts are ultimately needed to improve access to care and the overall health and survival for all individuals at risk for CKD, independent of their race, ethnicity, or socioeconomic status.     

Race, gender, and socioeconomic disparities in CKD in the United States

Chronic kidney disease (CKD) is a national public health problem beset by inequities in incidence, prevalence, and complications across gender, race/ethnicity, and socioeconomic status. As health care providers, we can directly address some factors crucial for closing the disparities gap. Other factors are seemingly beyond our reach, entrenched within the fabric of our society, such as social injustice and human indifference. Paradoxically, the existence of health inequities provides unique, unrecognized opportunities for understanding biologic, environmental, sociocultural, and health care system factors that can lead to improved clinical outcomes. Several recent reports documented that structured medical care systems can reduce many CKD-related disparities and improve patient outcomes. Can the moral imperative to eliminate CKD inequities inspire the nephrology community not only to advocate for but also to demand high-quality, structured health care delivery systems for all Americans in the context of social reform that improves the ecology, health, and well-being of our communities? If so, then perhaps we can eliminate the unacceptable premature morbidity and mortality associated with CKD and the tragedy of health inequities. By so doing, we could become global leaders not only in medical technology, as we currently are, but also in health promotion and disease prevention, truly leaving no patient behind.     

The impact of social determinants of health on the overall wellbeing of children: A review for the pediatric surgeon

Disparities in health care access, quality, and outcomes for pediatric patients, and their relationship to race and socioeconomic status (SES) have been extensively documented. The underlying causes behind such disparities have been less carefully studied, as clinicians and researchers often fail to look past immutable features such as race, into modifiable factors like social determinants of health (SDOH). A child's environment affects their patterns of social engagement, sense of security, and overall well-being. Resources such as affordable housing, access to education, public safety, and availability of healthy foods and safe play spaces impact and enhance quality of life, and have significant influence on both health and health care outcomes. These upstream indicators are often unrecognized or misidentified as health concerns. Few pediatric surgery publications discuss SDOH and their effects on children. This paper aims to introduce the five domains of SDOH (economic stability, education, social and community context, health and healthcare, and neighborhood and built environment) along with strategies to identify and address needs in these domains from a provider, hospital, and health system's perspective. It is anticipated that this information will serve as a foundation for pediatric surgeons to understand and develop processes that ameliorate disparities related to SDOH and improve surgical outcomes and the well-being of all children.     

Racial Differences in Determinants of Live Donor Kidney Transplantation in the United States

Few studies have compared determinants of live donor kidney transplantation (LDKT) across all major US racial‐ethnic groups. We compared determinants of racial‐ethnic differences in LDKT among 208 736 patients who initiated treatment for end‐stage kidney disease during 2005–2008. We performed proportional hazards and bootstrap analyses to estimate differences in LDKT attributable to sociodemographic and clinical factors. Mean LDKT rates were lowest among blacks (1.19 per 100 person‐years [95% CI: 1.12–1.26]), American Indians/Alaska Natives‐AI/ANs (1.40 [1.06–1.84]) and Pacific Islanders (1.10 [0.78–1.84]), intermediate among Hispanics (2.53 [2.39–2.67]) and Asians (3.89 [3.51–4.32]), and highest among whites (6.46 [6.31–6.61]). Compared with whites, the largest proportion of the disparity among blacks (20%) and AI/ANs (29%) was attributed to measures of predialysis care, while the largest proportion among Hispanics (14%) was attributed to health insurance coverage. Contextual poverty accounted for 16%, 4%, 18%, and 6% of the disparity among blacks, Hispanics, AI/ANs and Pacific Islanders but none of the disparity among Asians. In the United States, significant disparities in rates of LDKT persist, but determinants of these disparities vary by race‐ethnicity. Efforts to expand preESKD insurance coverage, to improve access to high‐quality predialysis care and to overcome socioeconomic barriers are important targets for addressing disparities in LDKT.     

A methodological note on modeling the effects of race: the case of psychological distress

Psychological distress is an important indicator of the mental well‐being of the population. Findings regarding racial differences in distress are inconclusive but may represent an important pathway through which disparities exist across a number of physical health outcomes. We used data from the 1994 Minority Health Survey, a nationally representative multiracial/ethnic sample of adults in US households, to examine racial/ethnic differences in psychological distress (n = 3623). Our primary study aim was to examine differences between additive and multiplicative models in assessing the influence of income and gender on the race/distress relationship. We hypothesized that additive models do not sufficiently account for potential interactions of race with income and gender, and may therefore mask important differences in distress between racial groups. The results suggest that our hypotheses were supported. After adjusting for income, there were no statistically significant differences in distress levels between racial groups. However, significant differences emerge when multiplicative models are used demonstrating the complexities of the intersection of race, income and gender in predicting psychological distress. Black men and women of higher income status represent a particularly vulnerable group, whereas Hispanic men are especially hardy. We discuss the implications of our findings for future work on racial health disparities. Copyright © 2008 John Wiley & Sons, Ltd.     

Use and awareness of prostate specific antigen tests and race/ethnicity

PURPOSE: This study is an assessment of racial and ethnic differences in the awareness and use of prostate specific antigen tests. MATERIALS AND METHODS: This is a secondary analysis of the 2000 National Health Interview Survey cancer control supplement. The subsample was 4,717 men 50 years old or older without prior prostate cancer. Outcomes were awareness and use of prostate specific antigen in a lifetime or the last year. Covariates included race/ethnicity, family income, education, age, perceived risk, health insurance and usual source of care. Multiple logistic regression was used to assess the effect of race/ethnicity on awareness and use of prostate specific antigen, controlling for covariates. Survey analysis procedures were used to account for the complex survey design. RESULTS: The association of race/ethnicity and the outcomes of awareness and lifetime prostate specific antigen use persisted when controlling for socioeconomic status, access and other variables. The largest differences were between Hispanic and non-Hispanic white men. Hispanic-American and black men were disadvantaged with respect to education, income and access to care, characteristics associated with lower use and awareness. In alternative models restricted to men aware of prostate specific antigen, neither race/ethnicity nor socioeconomic status was associated with use of prostate specific antigen. CONCLUSIONS: Race/ethnicity is associated with prostate specific antigen awareness and use. Lack of awareness of the prostate specific antigen test contributes to its lower use by racial/ethnic minorities. Future research should explore factors associated with lower use of the prostate specific antigen test by Hispanic men.
