Racial and Ethnic Disparities in Predictive Accuracy of Machine Learning Algorithms Developed Using a National Database for 30-Day Complications Following Total Joint Arthroplasty

BackgroundWhile predictive capabilities of machine learning (ML) algorithms for hip and knee total joint arthroplasty (TJA) have been demonstrated in previous studies, their performance in racial and ethnic minority patients has not been investigated. This study aimed to assess the performance of ML algorithms in predicting 30-day complications following TJA in racial and ethnic minority patients. MethodsA total of 267,194 patients undergoing primary TJA between 2013 and 2020 were identified from a national outcomes database. The patient cohort was stratified according to race, with further sub-stratification into Hispanic or non-Hispanic ethnicity. There were two ML algorithms, histogram-based gradient boosting (HGB), and random forest (RF), that were modeled to predict 30-day complications following primary TJA in the overall population. They were subsequently assessed in each racial and ethnic subcohort using discrimination, calibration, accuracy, and potential clinical usefulness. ResultsBoth models achieved excellent (Area under the curve (AUC) > 0.8) discrimination (AUCHGB = AUCRF = 0.86), calibration, and accuracy (HGB: slope = 1.00, intercept = -0.03, Brier score = 0.12; RF: slope = 0.97, intercept = 0.02, Brier score = 0.12) in the non-Hispanic White population (N = 224,073). Discrimination decreased in the White Hispanic (N = 10,429; AUC = 0.75 to 0.76), Black (N = 25,116; AUC = 0.77), Black Hispanic (N = 240; AUC = 0.78), Asian non-Hispanic (N = 4,809; AUC = 0.78 to 0.79), and overall (N = 267,194; AUC = 0.75 to 0.76) cohorts, but remained well-calibrated. We noted the poorest model discrimination (N = 1,870; AUC = 0.67 to 0.68) and calibration in the American-Indian cohort. ConclusionThe ML algorithms demonstrate an inferior predictive ability for 30-day complications following primary TJA in racial and ethnic minorities when trained on existing healthcare big data. This may be attributed to the disproportionate underrepresentation of minority groups within these databases, as demonstrated by the smaller sample sizes available to train the machine learning models. The ML models developed using smaller datasets (e.g., in racial and ethnic minorities) may not be as accurate as larger datasets, highlighting the need for equity-conscious model development.

Hospital Strain During the COVID-19 Pandemic and Outcomes in Older Racial and Ethnic Minority Adults

Marginalized populations have been disproportionately affected by the COVID-19 pandemic. Critically ill patients belonging to racial and ethnic minority populations treated in hospitals operating under crisis or near-crisis conditions may have experienced worse outcomes than White individuals. To examine whether hospital strain was associated with worse outcomes for older patients hospitalized with sepsis and whether these increases in poor outcomes were greater for members of racial and ethnic minority groups compared with White individuals. In this cross-sectional study, multivariable regression analysis was conducted to assess differential changes in all-cause 30-day mortality and major morbidity among older racial and ethnic minoritized individuals hospitalized with sepsis compared with White individuals and changes in hospital strain using Medicare claims data. Data were obtained on patients hospitalized between January 1, 2016, and December 31, 2021, and analyzed between December 16, 2023, and July 11, 2024. Time-varying weekly hospital percentage of inpatients with COVID-19. Composite of all-cause 30-day mortality and major morbidity. Among the 5 899 869 hospitalizations for sepsis (51.5% women; mean [SD] age, 78.2 [8.8] years), there were 177 864 (3.0%) Asian, 664 648 (11.3%) Black, 522 964 (8.9%) Hispanic, and 4 534 393 (76.9%) White individuals. During weeks when the hospital COVID-19 burden was greater than 40%, the risk of death or major morbidity increased nearly 2-fold (adjusted odds ratio [AOR], 1.90; 95% CI, 1.80-2.00; P < .001) for White individuals compared with before the pandemic. Asian, Black, and Hispanic individuals experienced 44% (AOR, 1.44; 95% CI, 1.28-1.61; P < .001), 21% (AOR, 1.21; 95% CI, 1.11-1.33; P < .001), and 45% (AOR, 1.45; 95% CI, 1.32-1.59; P < .001) higher risk of death or morbidity, respectively, compared with White individuals when the hospital weekly COVID-19 burden was greater than 40%. In this cross-sectional study, older adults hospitalized with sepsis were more likely to die or experience major morbidity as the hospital COVID-19 burden increased. These increases in adverse outcomes were greater in magnitude among members of minority populations than for White individuals.

Building partnerships to improve clinical trial accrual in rural and Native American communities through community health educator interventions.

180 Background: Rural populations and racial minorities are often underrepresented in cancer clinical trials. The low representation is determined by multilevel factors, including lack of geographic access to facilities in rural locations and mistrust in the medical and scientific community. Presented here are partial results of an educational intervention to improve clinical trials-related knowledge among rural residents and racial minorities. Methods: The Center to Reduce Cancer Health Disparities (CRCHD) from the National Cancer Institute (NCI) developed the study materials, that were available in English or Spanish, to be utilized according to participants' preferences. The University of Wisconsin Carbone Cancer Center implemented this intervention in northern Wisconsin, which consisted of a baseline questionnaire, a recorded educational intervention, and a post-educational questionnaire. The chosen community is largely rural and Native. The questionnaires consisted of 11-knowledge- and 6-intention-related questions. After being screened by the rural Community Health Educator (CHE), subjects self-administered the intervention online or received the intervention from the CHE during tribal or other educational group events in rural communities. Results: Between January and May 2024, 62 participants started the intervention. Participants’ mean age was 45.1 (±15.36) years, 64.5% (40/62) were female, and 53.2% (33/62) self-identified as American Indian/ Alaska Native. All resided in rural community, defined as Rural-Urban Continuum Codes 7 or 8. Three participants did not respond to the post-educational questionnaire, and one skipped its intentions section. Although the two questions about informed consent presented the highest percent of correct answers post-intervention, the median total knowledge score pre and post-intervention remained the same (p&gt;0.05). Post-intervention, participants more often agreed it is important for minority groups to participate in clinical trials, reported being likely to search for a clinical trial they might be eligible for, join a clinical trial, and talk to family/friends about joining a clinical trial (p&lt;0.05). Conclusions: The CHE successfully engaged rural community members to participate in the intervention. In addition, the intervention facilitated building trust and partnerships for future cancer-related community driven work.

Moderating effects of organizational minority representation on racial and ethnic differences in early palliative care receipt among patients diagnosed with advanced cancers in 2010-2019 in the US.

52 Background: Early palliative care (PC) is recommended for advanced cancers, but differential use has been documented by race and ethnicity. We examined whether racial and ethnic differences in early PC use were moderated by organization-level proportions of minority patients served. Methods: We identified patients aged ≥65.5 years diagnosed with advanced-stage breast, colorectal, non-small cell lung (NSCL), small cell lung (SCL), pancreas, and prostate cancers in 2010-2019 with ≥6 months survival and continuous fee-for-service coverage from the SEER-Medicare data. Early PC was identified by PC encounter diagnosis codes or hospice and palliative medicine (HPM) specialty codes within 90 days post-diagnosis or up to first hospice admission date. Treating physicians and organizations were assigned based on the plurality of visits within 180 days surrounding diagnosis. Using patient race and ethnicity information, organizations were classified based on the percent of racial and ethnic minorities patients (Low&lt;10%, Medium 10-19%, and High Minority-Serving ≥20%). Multivariable logistic models assessed interacting effects of organizations’ minority representation and individual race and ethnicity on early PC receipt, adjusting for patient characteristics. Results: Among 102,060 patients treated at 8,039 organizations, the percent receiving early PC increased from 1.44% in 2010 to 10.30% in 2019. High Minority-Serving organizations were larger size and more likely to employ a HPM specialist and to treat a higher proportion of patients in metropolitan but lower socioeconomic areas, and were dually Medicare-Medicaid eligible. After adjusting for patient characteristics, Hispanic patients were 1.6 percentage points (ppts, 95%CI=-3.1, -0.1) less likely to receive early PC than Non-Hispanic (NH) White patients in Low Minority-Serving organizations. In High Minority-Serving organizations, Hispanic and NH Black patients were 0.8 ppts (95%CI=0.1, 1.6) and 1.6 ppts (95%CI=1.0, 2.3) more likely to receive early PC than NH White patients. (Table). Conclusions: Racial and ethnic minorities were more likely to receive early PC than NH White at High Minority-Serving organizations but not Medium/Low Minority-Serving organizations. System-level factors may be modified to narrow racial and ethnic differences in early PC use. Adjusted difference in early palliative care by race and ethnicity. Organization Minority Representation Individual Adjusted Probability Difference (95% CI) Low NH White Ref Hispanic -1.6 (-3.1, -0.1) NH Black 0.01 (-1.7, 1.7) Other/Unknown 1.1 (-1.2, 3.4) Medium NH White Ref Hispanic -0.6 (-1.7, 0.5) NH Black -0.8 (-1.7, 0.2) Other/Unknown 0.4 (-0.9, 1.7) High Non-Hispanic White Ref Hispanic 0.8 (0.1, 1.6) NH Black 1.6 (1.0, 2.3) Other/Unknown -0.3 (-1.1, 0.4)

Survival Difference of Colorectal Adenocarcinoma Among Racial and Ethnic Minority Groups: A SEER Database Study.

Despite advances in diagnosis and treatment, racial disparities continue to exist in colorectal cancer (CRC) survival. This study aims to characterize the CRC survival differences among racial and ethnic minority groups. The Surveillance, Epidemiology, and End Results (SEER) database was used to identify adults diagnosed with CRC from 2015 to 2019. Demographics, disease characteristics, surgical treatment, stages, and survival data for individuals who are Hispanic, Black, Southeast Asian, Chinese, American Indian and Alaskan Native (AIAN), Asian Indian and Pakistani (AIP), and Native Hawaiian and Other Pacific Islanders (NHOPI) were extracted. Survival analysis was done using the Kaplan-Meier survival curve. Multivariate analysis was done with the Cox proportional hazard model. There were 40 091 individuals with CRC. NHOPI had the youngest median age of 59 years, while Chinese individuals had the oldest median age of 65 years. From the total sample of their respective subgroups, 43.8% of Black patients and 36.7% of AIAN patients had a median household income of <$60 000, while 55.3% of Southeast Asian patients, 59.7% of Chinese patients, 55.8% of AIP patients, and 65.6% of NHOPI patient had a median household income >$70 000. The 1-year survival rate was lower for patients who were Hispanic (62.0%), Black (60.9%), and AIAN (63.1%). Even after multivariate analysis, Black patients had a significant hazard ratio (HR) of 1.21 (95% confidence interval [95% CI]: 1.05-1.38), while AIP had a HR of 0.68 (95% CI 0.55-0.84), compared to AIAN. Other significant variables that were linked with survival included older age, advanced stage of CRC, a median household income <$60 000, male sex, no surgery, subtotal colectomy/hemicolectomy, and total colectomy. Further studies are needed to elucidate the specific causes of these differences and create appropriate strategies to reduce this survival disparity.

Health care disparities and bladder cancer mortality in the United States: A closer look at the social vulnerability index.

150 Background: Bladder cancer is a significant public health concern, with various factors influencing mortality rates. The Social Vulnerability Index (SVI) measures community resilience to external health stresses. This study investigates the association between bladder cancer mortality (BCM) and county-level SVI in the United States (U.S.). Methods: Mortality data from U.S. counties were obtained from the Centers for Disease Control (CDC) and Prevention Wide-Ranging Online Data for Epidemiologic Research (WONDER) database from 2015 to 2019 using the International Classification of Diseases-10th Edition (Code C67). The CDC and Agency for Toxic Substances and Disease Registry (ATSDR) county-level SVI was used as a composite measure of social vulnerability. The SVI includes several U.S. census variables grouped into four themes: Socioeconomic Status (SES), Household Characteristics, Racial and Ethnic Minority Status, and Housing Type and Transportation. Vulnerable SES variables include individuals with incomes below 150% of the federal poverty line, unemployment, those with housing cost burdens, and those without high school diplomas or health insurance. Vulnerable household variables include seniors over 65 years, children under 17 years, disabled civilians, single-parent households, and those with limited English proficiency. SVI Quartiles (Q1 being the least vulnerable and Q4 the most vulnerable) were compared to assess their impact on BCM. Negative binomial regression models were used to estimate Incidence Rate Ratios (IRRs) with 95% Confidence Intervals (CIs) using SAS software. Results: From 2015 to 2019, a total of 82,994 people died from bladder cancer, and the age-adjusted mortality rate per 1,000,000 was 42.4. A higher SVI in intermediate vulnerability quartiles was associated with a higher risk of BCM (Q2 and Q3: IRR = 1.06; 95% CI = 1.01-1.10; p = 0.009) compared to the least vulnerable quartile, Q1. Vulnerable SES had an increased risk of BCM (Q2 and Q3: IRR = 1.07; 95% CI = 1.03-1.12; p &lt; 0.001) compared to Q1. BCM was also increased in individuals with vulnerable household characteristics (Q2 and Q3: IRR = 1.06; 95% CI = 1.02-1.10; p = 0.004) compared to Q1. Q4 was not significant in comparison to Q1 for the groups mentioned above. Interestingly, Racial and Ethnic Minority Status (Hispanic, Latino, African American, etc.) was associated with lower BCM in Q2 and Q3 (IRR = 0.88; 95% CI = 0.84-0.92; p &lt; 0.001) and Q4 (IRR = 0.77; 95% CI = 0.73-0.81; p &lt; 0.001) compared to Q1. No significant mortality differences were observed among vulnerable Housing Types and Transportation. Conclusions: Bladder cancer mortality is linked to vulnerable socioeconomic and household characteristics, while racial and ethnic minority status correlates with decreased risk. Future targeted public health interventions are needed to reduce bladder cancer mortality in vulnerable populations. Bladder cancer mortality and its association with social vulnerability quartiles.

Wildfire-sourced fine particulate matter and preterm birth risks in Brazil: a nationwide population-based cohort study

Wildfire-specific particulate matter with diameters ≤ 2.5µm (PM2.5) is the key component of wildfire smoke, with potentially higher toxicity than PM2.5 from other sources. In this nationwide population-based cohort study, we included 22,163,195 births from Brazil during 20102019. Daily wildfire-specific PM2.5 was estimated through the chemical transport model. Time-varying Cox proportional hazards models were used to characterize the exposure-time-response (E-T-R) relationship between weekly wildfire-specific PM2.5 exposure and preterm birth (PTB) risks, followed by subgroup analyses. A 10µg/m3 increment in wildfire-specific PM2.5 was associated with a hazard ratio of 1.047 (95% confidence interval [CI]: 1.032–1.063) for PTB. Stronger associations between wildfire-specific PM2.5 and PTB were observed during earlier pregnancy, among female infants, and pregnant women <18 years old, in ethnic minorities, with a length of education ≥11 years, from low-income or high-temperature municipalities, and residing in North/Northeast regions. An estimated 1.47% (95% CI: 1.01%1.94%) of PTBs were attributable to wildfire-specific PM2.5 in Brazil, increasing from 2010 to 2019. The PTBs attributable to wildfire-specific PM2.5 surpassed those attributed to non-wildfire PM2.5 (0.31%, 95% CI: 0.09%0.57%). Wildfire emerged as a critical source contributing to the PM2.5-linked PTBs. Prioritized fire management and emission control strategies are warranted for PTB prevention.

Food for Cancer Health Equity: The impact of a culturally tailored food voucher intervention on food insecurity among Latinx patients with cancer.

182 Background: Food insecurity disproportionately impacts immigrant, low-income, and racial and ethnic minorities with cancer. In our prior qualitative work, Latinx and multiethnic patients with food insecurity emphasized the importance of culturally-tailored food assistance interventions that could minimize stigma and maintain self-efficacy and autonomy. In collaboration with Latinx patients and community partners in Monterey County, California, we co-developed a culturally-tailored food voucher intervention. In this study, we conducted a pilot of the intervention among multiethnic and Latinx patients with cancer and tested the impact on food insecurity and health-related quality of life. Methods: We recruited low-income, racial and ethnic minority adults &gt; 18 years of age who screened positive for food insecurity using the 2-item Hunger Vital Sign while receiving cancer treatment in a clinic in Monterey County, CA between July 2023 until August 2023. All participants who consented to participate received $40 monthly grocery store gift cards redeemable at a variety of local retailers for 6 months in addition to usual care provided by trained community health workers who assisted with other health-related social needs. We conducted validated surveys at baseline (time of enrollment) and 6-month follow-up (post-intervention) assessing demographics, food behaviors, food insecurity, and health-related quality of life, as well as feasibility and acceptability of the intervention. We compared pre- and post-intervention proportions with food insecurity using McNemars tests and change in health-related quality of life using paired t-tests. Results: Of the 30 study participants enrolled, 27 (90%) were Latinx; 24 (80%) spoke Spanish as their preferred language; 16 (53%) had advanced (stage 3 or 4) cancer; 12 (40%) were retired or unemployed; 10 (33%) were disabled; 20 (67%) reported a household income &lt; $35,000 USD. Of the 26 (87%) participants who completed post-intervention surveys, the proportion with food insecurity decreased from 100% to 65% (95% CI 0.60-0.77; p = 0.01); 100% adhered to recommended treatment; and health-related quality of life scores increased by 8 points from 71.9 +/-16.1 to 79.5+/- 10.5 (p = 0.02) from baseline. All (100%) participants rated the program as feasible and acceptable in post-intervention surveys. Conclusions: This culturally-tailored food voucher intervention was associated with reductions in food insecurity and improvements in health-related quality of life among low-income Latinx patients with cancer. This intervention may represent an effective and acceptable approach to overcome food insecurity in Latinx and multiethnic patients with cancer.

Socioeconomic and medical determinants of state-level subjective cognitive decline in the United States.

It is important to understand the socioeconomic and medical determinants of subjective cognitive decline (SCD) at a population level in the United States. The primary outcomes are state-level rates of SCD and SCD-related functional impairment in adults aged ≥ 45, both measured in the Behavioral Risk Factor Surveillance System from 2016 to 2022. The exposures are state-level rates of poverty, unemployment, homelessness, college education, racial and ethnic minorities, uninsurance, smoking, hypertension, diabetes, and obesity as well as household income and physician density. The strongest state-level associations with rates of SCD were the prevalence of diabetes (rho=0.64), hypertension (rho=0.59), and poverty (rho=0.58; all p<0.001), and with SCD-related functional impairment were prevalence of poverty (rho=0.71), diabetes (rho=0.68), and hypertension (rho=0.53; all p<0.001). This study highlights critical links between SCD and socioeconomic and medical determinants in adults aged ≥ 45 in the United States, including the prevalence of poverty, diabetes, and hypertension. State-level analysis reveals socioeconomic and medical risk factors for subjective cognitive decline (SCD) at a population level. The prevalence of poverty is a critical contributor to the state-level prevalence of SCD. The prevalence of diabetes and hypertension are also strong state-level determinants of SCD. Addressing the burden of cognitive decline at the population level necessitates targeting socioeconomic and medical factors.

The relationship between radiation oncology department NIH funding and institutional community inclusion/investment.

153 Background: Disparities in healthcare access and funding allocation persist among racial minorities and low-income populations. Radiation Oncology departments play a crucial role in cancer treatment, yet the extent to which these departments serve historically underrepresented communities following receipt of National Institutes of Health (NIH) funding remains unclear. This study accessed the relationship between radiation oncology departments that are awarded National Institute of Health (NIH) funding and Lown Institute Hospitals Index rankings for community benefit and inclusivity. Methods: Radiation oncology departments awarded funding from the NIH from 2019-2021 were retrospectively studied. The 2023 Lown Institute Hospital Index rankings for community benefit and inclusivity were examined. The community benefit metric measures financial assistance spending, community investment spending, and Medicaid as a portion of patient revenue. The inclusivity metric measures the similarities of income, race, and education level between the hospital patient population and the surrounding community. Kendall’s correlation coefficient (tau value) and linear regression were used to evaluate the relationship between measures of community benefit and inclusivity and NIH radiation oncology department research funding. Results: Twenty-two radiation oncology departments that received NIH funding (median = $ 419,555.00) were included. A statistically significant positive correlation was observed between the amount of radiation oncology NIH research funding received and institutional rankings for overall community benefit (tau = 0.378; P &lt; 0.034), with a trend towards significance for institutional rankings for community investment spending (tau = 0.497; P &lt; 0.053). No significant correlation was observed between the amount of radiation oncology department funding and institutional rankings for charity care spending (P = 0.430), Medicaid as a portion of patient revenue (P = 0.837), and service of patients from racial and or ethnic minorities (P = 0.505), with low income (P = 0.612), or with lower levels of education (P = 0.700). Conclusions: Our study highlights the relationship between recent NIH funding received by Radiation Oncology departments and their commitment to community health and inclusivity. Our findings indicate a significantly positive correlation between NIH funding received by radiation oncology departments and overall community benefit. This suggests that departments receiving NIH funding may be incentivized to allocate resources towards initiatives to improve community health outcomes beyond direct patient care. This study prompts further exploration into the mechanisms through which NIH-funded radiation oncology departments allocate resources and engage with their surrounding communities.

Enhancing minority participation in cancer clinical trials: Insights from a mixed methods study.

70 Background: The urgency to enhance cancer clinical trial enrollment among racial and ethnic minority patients is underscored by the rise in novel therapies. This study examines referral mechanisms from a community-based oncology care clinic to an academic medical center, evaluates the clinical trial knowledge of minority groups, and explores perceptions and attitudes toward trials. Methods: Using a sequential explanatory mixed methods research design, Clinical Trial Knowledge Survey was administered to patients seen at the Hem/Onc clinic in a community-medical center. Descriptive statistics were calculated and multivariate analysis were used to examine associations between variables using STATA 18. Qualitative data from 10 semi-structured interviews were analyzed by two independent investigators using NVivo 14. Themes were identified through a combination of deductive and inductive approaches. Results: Of the 502 mailers sent, 97 individuals responded (response rate of 9.56%). Average age of participants was 54 years, predominantly single and African American. Majority of the of respondents (62%) agreed that patient participation is crucial for generating new and effective treatments. 65% believed that clinical trials are typically conducted on drugs presumed to be effective. However, 32.99% of the respondents perceived participation in clinical trials as a frightening experience. Four qualitative themes emerged: (i) Engagement with one’s health varied between participants. (ii) While clinical trial awareness was limited, willingness to participate was strongly endorsed. (iii) Clinical trial decision-making is a complex process heavily influenced by awareness of and attitudes toward clinical trials. (iv) There is a need to tailor educational strategies to increase awareness of and participation in clinical trials. Conclusions: Our findings emphasize the critical role of awareness and tailored, culturally congruent educational strategies that are crucial to bridge the knowledge gap, alleviate hesitations, and enhance cancer clinical trial participation rates among racial and ethnic minorities.

Enhancing Science Affinities of Ethnic Minority High School Students Through Online Interactions with Cultural Role-Models of Scientists and Engineers During the COVID-19 Pandemic: A Case Study

This case study aims to investigate the effectiveness of an online science enhancement program in retaining ethnic minority students in science by providing them with opportunities to interact with cultural role-models of scientists and engineers during the COVID-19 pandemic. The study draws on foundational theories of identity formation and attitudes towards science, as well as research on growth mindsets, to increase students’ participation in science and assess the program’s effects, while also collecting data to develop a new theory. The findings indicate that the online enhancement program successfully facilitated the formation of science identities among the 12 ethnic minority high school students, enhanced their interest in science, and fostered positive attitudes towards science during the pandemic. Moreover, the online interactions with cultural role-models of scientists and engineers supported the students’ science learning and reinforced their science identity. This study also provides guidelines for future research on designing online enrichment programs to enhance ethnic minority students’ science affinities.

A community health worker–led intervention to improve patient knowledge and receipt of precision medicine: Updated ALCANCE randomized clinical trial findings.

181 Background: Inequitable access to precision medicine limits its impact. To address disparities, we co-developed the Addressing Latinx Cancer Care Equity Study (NCT04843332), a multi-level intervention with community stakeholders. ALCANCE was designed for low-income and Latinx adults with cancer in rural Monterey County, California. We provided annual training for clinicians about testing guidelines and precision medicine disparities. Trained CHWs educated patients about precision medicine and encouraged them to raise the topic with their oncologist. We tested whether the intervention improved patient knowledge and receipt of precision medicine. Methods: Patients with newly diagnosed or recurrent cancer, age ≥ 18 years, able to consent in English or Spanish, and who self-identified as a racial and ethnic minority OR low-income status OR were insured by public or agricultural company insurance OR uninsured and receiving cancer care at Pacific Cancer Care, a rural community oncology practice in Monterey County, were randomized 1:1 to usual care (control group) or usual care augmented with the multi-level intervention for 12 months (intervention group). The primary outcome was whether the multilevel intervention could increase patient knowledge of precision medicine using a validated 6 question survey from time of enrollment (baseline) to 6-months post-enrollment between groups. A secondary outcome was receipt of precision medicine. CHWs and clinicians completed semi-structured interviews. Results: 110 participants were randomized; 70% (n = 67) reported Spanish as their primary language; 81% (n = 89) identified as Hispanic. Median age was 55 years (55.4 ± 14.3, mean± SD); majority had annual household incomes (USD) ≤ $34,999 (59.0%, n = 46); majority obtained a high school diploma/GED or less (67.3%, n = 74). Most had gastrointestinal (35.5%, n = 39) and breast (24.5%, n = 27) cancers and were diagnosed with stage 3 or 4 (64.5%, n = 71) disease. Precision medicine knowledge was low at baseline across both the control and intervention groups (23.5 ± 19.3 versus 23.0 ± 17.7, respectively). Intervention group participants had greater precision medicine knowledge at 6-months (39.2 ± 23.0) than control group participants (24.2 ± 20.0) with greater increase in knowledge overtime than control group participants (p &lt; 0.001). More intervention group participants (n=46, 79.3%) received precision medicine testing than control (n=34, 60.7%). Across both groups, 26 of those tested had an actionable mutation. Of those 26, 66.7% (n=6 of 9) in the control group and 94.1% (n=16 of 17) in the intervention group received targeted therapy (p=0.065). Interviews with the care team indicated the model was acceptable and has been sustained as part of usual care. Conclusions: CHW-facilitated interventions may reduce disparities in precision medicine cancer care. Clinical trial information: NCT04843332

A qualitative study identifying the navigation needs of patients with HCC.

263 Background: Hepatocellular carcinoma (HCC), the 2 nd leading cause of cancer mortality, disproportionately affects racial and ethnic minorities. Disparities in risk are compounded by profound differences in HCC treatment and survival. Black patients are consistently diagnosed at more advanced stages, least likely to receive treatment, and have the lowest survival. In other cancer types, navigation facilitates successful treatment and improves outcomes. To inform development of a longitudinal navigation program, we aimed to ascertain the needs of HCC patients, and identify obstacles limiting access to cancer treatment and supports needed for successful HCC treatment from the vantage point of patients and other stakeholders. Methods: In-depth, one-hour qualitative interviews were conducted with 40 individuals (14 patients, 7 caregivers, 8 advocates, and 11 providers) in English or Spanish. Providers included physicians, advanced practice providers, social workers, nurse navigators, and transplant coordinators involved in HCC care. We recruited patients, caregivers, and providers from the Sylvester Comprehensive Cancer Center and Jackson Health System; advocates were recruited through partnerships with Global Liver Institute and the Hepatitis B Foundation. Results: The interviews identified five overarching themes representing navigation needs of HCC patients: (1) Education/ Health Literacy, (2) Financial Resources, (3) Coordination of Care, (4) Emotional Management, and (5) Social Support.

Living on an Island: Start-Ups, Spatial Heterogeneity and Remote Entrepreneurial Ecosystems

In this paper we focus specifically on start-ups in remote island entrepreneurial ecosystems (EEs) and consider the differences between these entrepreneurs compared to their mainland Scottish and UK counterparts. We find that Island new start-up entrepreneurs tend to be older, less well educated, more likely to be female, and less likely to be from an ethnic minority. They borrow similar amounts of start-up capital than their mainland counterparts and are equally likely to survive. Despite their geographical remoteness, this suggests that entrepreneurial activity makes a meaningful contribution to their respective EEs.

Racial and Ethnic Disparities in the Time to Ovarian Cancer Surgery in Patients at an Integrated Health Care Delivery System.

Disparities in ovarian cancer survival for African American women are multifactorial. We evaluated racial and ethnic differences in time to ovarian cancer surgery in members of an integrated health care system. In this retrospective cohort study, we identified women diagnosed with invasive epithelial-type ovarian cancer between January 1, 2008, through December 31, 2014, at an integrated health care system in the United States. We extracted data on cancer-related variables and sociodemographic variables from the health care system's cancer registry and electronic health records. We included patients who received ovarian cancer surgery without neoadjuvant chemotherapy. We defined time to surgery as the number of days between diagnostic imaging study and surgery. We used Cox proportional hazards regression to evaluate crude and adjusted association of race and ethnicity with time to surgery. Of 872 patients included, 55.1% were non-Hispanic White (hereafter, White), 24.9% were Hispanic, 14.6% were Asian/Pacific Islander (PI)/Native American, and 5.5% were African American. Median age at diagnosis was 59.0 years. African American patients were diagnosed at an older age and were more likely to come from deprived neighborhoods than other racial and ethnic groups. Median time to surgery was longer for African American patients compared with White, Hispanic, and Asian/PI/Native American patients (median days: 27.5 vs 21.0, 24.5, and 26.0, respectively; P<.0001). In adjusted models, the likelihood of having received surgery at any given time post diagnostic imaging was 31% lower for African American patients compared with White patients (HR, 0.69; 95% CI, 0.51-0.93). This likelihood was also lower for Hispanic and Asian/PI/Native American patients, but not statistically significant. Our findings showed that patients with ovarian cancer from racial and ethnic minorities had a lower likelihood of having received surgery at any given time post diagnostic imaging compared with White patients, demonstrating that racial and ethnic differences exist in time to ovarian cancer surgery in patients with relatively equal access to care.

Wound Care at the Intersection of Race, Ethnicity, and Malnutrition.

Ensuring adequate nutrition is vital for maintaining skin health and promoting successful wound healing. Globally, the rise in malnutrition and diet-related diseases is contributing to increased rates of illness and disability. Populations in food deserts and those experiencing food insecurity are particularly at risk. Being at risk for or having malnutrition associated with chronic conditions such as diabetes and cardiovascular disease can increase the incidence of wounds. Healthcare disparities and varied clinical outcomes among ethnic minorities further contribute to these challenges. Research indicates that racial and ethnic minorities experience a higher prevalence and severity of wounds, including pressure injuries. Detecting early-stage wounds in individuals with darker skin tones can be difficult, adding to the disparities.Culturally appropriate nutrition interventions are essential in addressing these health inequities because tailored approaches tend to be more effective than uniform strategies. Understanding diverse dietary patterns and incorporating cultural food preferences into care plans can improve patient adherence and outcomes. Promoting equity in wound care through culturally sensitive practices helps to foster respect, dignity, and trust within healthcare settings, particularly for minority populations.In this review, the authors highlight the need for inclusive interventions that provide culturally aligned nutrition, supporting patients' clinical and holistic well-being.

Trends and Patterns in Hypertension-Related Deaths: A Comprehensive Analysis Using Center for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) Data.

Hypertension (HTN) is a leading cause of cardiovascular morbidity and mortality worldwide. Despite advances in treatment, includingthe development and use of vasodilator-β-blocker combination and treatment with antihypertensive agents, HTN-related deaths have shown concerning trends. As such, the objective of this study is to examine the trends, disparities, and demographic variations in HTN-related mortality over a decade and to identify key factors contributing to these patterns, includinggenetics, dietary habits, structural discrimination in access to healthcare, lifestyle choices, and secondary hypertension, which is due to underlying conditions like kidney disease, hormonal disorders, or certain medications. To attain this objective, this retrospective study has utilized data from the Center for Disease Control and Prevention'sWide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to assess HTN-related mortality rates from 2010 to 2020. Age-adjusted mortality rates were calculated, and subgroup analyses were conducted by gender, race/ethnicity, and age groups. Temporal trends were analyzed to identify significant changes in mortality rates over time. Moreover, IBM SPSS Statistics, version 29 (IBMCorp., Armonk, NY) was used in the analysis, while 95% confidence intervals (CIs), were calculated to demonstrate the temporary trend of mortality rates overall and by age, sex, ethnicity, and region. Therefore, themortality data from 2010 to 2020 show significant trends and variations across demographic groups. Overall, HTN-related mortality rate inthe United States increased from 5.1 per 100,000 in 2010 to 6.4 in 2020, reflecting a general upward trend. For males, the rate rose from 4.8 to 6.6 per 100,000 during the same period. Racial disparities are notable, with Black or African American individuals having the highest mortality rates, increasing from 9.6 to 11.2 per 100,000. Age-specific data reveal that mortality in the 65-74 age group more than doubled, from 10.3 to 16.2 per 100,000, while in the 75-84 age group, it rose from 32.1 to 35.7. The 85+ age group had the highest rates, increasing from 144.0 to 155.0 per 100,000. States with the highest age-adjusted rates include Mississippi, Georgia, West Virginia, California, and Alabama. The studyfindings highlight the growing burden of HTN-related mortality in the United States, particularly among males, racial minorities, and older adults. This situation underscores the need for targeted public health interventions, which include creation of hypertension awareness in minority groups and enhancing medication adherence especially among Blacks, and addressing the social determinants of health contributing to higher HTN rates and poorer outcomes, including disadvantaged neighborhoods, structural discrimination and racism, and limited access to healthcare. The study found that African Americans are likely to be diagnosed with HTN earlier in life with higher HTN-related mortality thanWhites, andwith 50% increased risk of cardiovascular disease mortality. Continuous efforts are required to aptly address such disparities contributing to ongoing HTN treatment and care inequalities.

What Explains Voting for DENK: Issues, Discrimination or In-group Favouritism?

ABSTRACT Why do ethnic and religious minorities vote for DENK? DENK is the first pro-Turkey and pro-Islam party represented in Dutch parliament, led by Turkish- and Moroccan-origin politicians who openly profess to practicing Islam. Drawing on an original survey (N= 905) among Dutch voters in which we oversampled those with Turkish, Moroccan and Surinamese roots, we put three possible explanations to the test: issues, discrimination and in-group favouritism. Each subsample is religiously mixed and includes Muslims and/or Christians and voters who are not religious. While ethnic in-group favouritism, feelings of belonging in the Netherlands, experiences with discrimination and issues sometimes explain voting for DENK, Muslim in-group favouritism is the decisive factor. These findings contribute to understanding voting behaviour in increasingly religiously diverse European immigration societies.
