RESUMO
BACKGROUND: Despite Medicare coverage, financial hardship is a prevalent issue among those diagnosed with cancer at age 65 years and older, particularly among those belonging to a racial or ethnic minority group. Sociodemographic, clinical, and area-level factors may mediate this relationship; however, no studies have assessed the extent to which these factors contribute to the racial/ethnic disparities in financial hardship. METHODS: Surveys assessing financial hardship were completed by 721 White (84%) or Black (16%) patients (aged 65 years and older) who were diagnosed with breast (34%), prostate (27%), lung (17%), or colorectal (14%) cancer or lymphoma (9%) at the University of Alabama at Birmingham between 2000 and 2019. Financial hardship included material, psychological, and behavioral domains. Nonlinear Blinder-Oaxaca effect decomposition methods were used to evaluate the extent to which individual and area-level factors contribute to racial disparities in financial hardship. RESULTS: Black patients reported lower income (65% vs. 34% earning <$50,000) and greater scores on the Area Deprivation Index (median, 93.0 vs. 55.0). Black patients reported significantly higher rates of overall (39% vs. 18%), material (29% vs. 11%), and psychological (27% vs. 11%) hardship compared with White patients. Overall, the observed characteristics explained 51% of racial differences in financial hardship among cancer survivors, primarily because of differences in income (23%) and area deprivation (11%). CONCLUSIONS: The current results identify primary contributors to racial disparities in financial hardship among older cancer survivors, which can be used to develop targeted interventions and allocate resources to those at greatest risk for financial hardship.
RESUMO
OBJECTIVE: To investigate the effect of racial residential segregation on disparities between Black and White patients in stage at diagnosis, receipt of surgery, and survival. METHODS: Subjects included Black and White patients diagnosed with ovarian cancer between 2005 and 2015 obtained from the Surveillance, Epidemiology, and End Results Program. Demographic data were obtained from the 2010 decennial census and 2013 American Community Survey. The exposure of interest was the index of dissimilarity (IOD), a validated measure of segregation. The outcomes of interest included relative risk of advanced stage at diagnosis and surgery for localized disease, 5-year overall and cancer-specific survival. RESULTS: Black women were more likely to present with Stage IV ovarian cancer when compared to White (32% vs 25%, p < 0.001) and less often underwent surgical resection overall (64% vs 75%, p < 0.001). Increasing IOD was associated with a 25% increased risk of presenting at advanced stage for Black patients (RR 1.25, 95% CI 1.08, 1.45), and a 15% decrease for White patients (RR 0.85, 95% CI 0.73, 0.99). Increasing IOD was associated with an 18% decreased likelihood of undergoing surgical resection for black patients (RR 0.82, 95% CI 0.77, 0.87), but had no significant association for White patients (RR 1.01, 95% CI 0.96, 1.08). When compared to White patients in the lowest level of segregation, Black patients in the highest level of segregation had a 17% higher subhazard of death (HR 1.17, 95% CI 1.07, 1.27), while Black patients in the lowest level of segregation had no significant difference (HR 1.13, 95% CI 0.99, 1.29). CONCLUSION: Our findings demonstrate the direct harm of historical government mandated segregation on Black women with ovarian cancer.

INTRODUCTION: Urban firearm violence (UFV) is associated with inequities rooted in structural racism and socioeconomic disparities. Social vulnerability index (SVI) is a composite measure that encompasses both. We sought to understand the relationship between SVI and the incidence of UFV in Chicago using geospatial analysis for the first time. MATERIALS AND METHODS: Firearm assaults in Chicago 2001-2019 were obtained from the Trace. Locations of incidents were geocoded using ArcGIS and overlaid with census tract vector files. These data were linked to 2018 SVI measures obtained from the Center for Disease Control and Prevention. Shooting rates were calculated by tabulating the total number of shootings per capita in each census tract. We used Poisson regression with robust error variance to estimate the incident rate of UFV in different levels of social vulnerability and Local Moran's I to evaluate spatial autocorrelation. RESULTS: In total, 642 census tracts were analyzed. The median shooting rate was 2.6 per 1000 people (interquartile 0.77, 7.0). When compared to those census tracts with very low SVI, census tracts with low SVI had a 1.7-time increased incident rate of shootings (incidence rate ratio [IRR] 1.74, 95% CI 1.08, 2.81), tracts with moderate SVI had a 3.1-time increased incident rate (IRR 3.07, 95% CI 2.31, 4.10), and tracts with high SVI had a 7-time increased incident rate (IRR 7.03, 95% CI 5.45, 9.07). CONCLUSIONS: In Chicago, social vulnerability has a significant association with rates of firearm violence, providing a focus point for policy intervention to address high rates of interpersonal violence in similar cities.

OBJECTIVE: To understand the mediating effect of socioeconomic factors on the association between residential segregation and racial disparities in pancreatic cancer (PC). BACKGROUND: Black patients with PC present at a later stage and have worse mortality than White patients. These disparities have been explained by the level of residential segregation. METHODS: Data were obtained from Surveillance, Epidemiology, and End-Results (SEER) and included all Black and White patients who were diagnosed with PC between 2005 and 2015. The primary exposure variable was the Index of Dissimilarity, a validated measure of segregation. County-level socioeconomic variables from the US Census were assessed as mediators. The primary outcomes were advanced stage at diagnosis, surgical resection for localized disease, and overall mortality. Generalized structural equation modeling was used to assess the mediation of each of the socioeconomic variables. RESULTS: Black patients in the highest levels of segregation saw a 12% increased risk [relative risk=1.12; 95% confidence interval (CI): 1.08, 1.15] of presenting at an advanced stage, 11% decreased likelihood of undergoing surgery (relative risk=0.89; 95% CI: 0.83, 0.94), and 8% increased hazards of death (hazard ratio=1.08; 95% CI: 1.03, 1.14) compared with White patients in the lowest levels. The Black share of the population, insurance status, and income inequality mediated 58% of the total effect on the advanced stage. Poverty and Black income immobility mediated 51% of the total effect on surgical resection. Poverty and Black income immobility mediated 50% of the total effect on overall survival. CONCLUSIONS: These socioeconomic factors serve as intervention points for legislators to address the social determinants inherent to the structural racism that mediate poor outcomes for Black patients.

OBJECTIVE: To determine the impact of income mobility on racial disparities in colorectal cancer. BACKGROUND: There are well-documented disparities in colorectal cancer treatment and outcomes between Black and White patients. Socioeconomic status, insurance, and other patient-level factors have been shown important, but little has been done to show the discriminatory factors that lead to these outcomes. METHODS: Data were obtained from the Surveillance Epidemiology and End-Results database for Black and White patients with colorectal cancer between 2005 and 2015. County level measures of Black (BIM) and White income mobility (WIM) were obtained from the Opportunity Atlas as a measure of intergenerational poverty and social mobility. Regression models were created to assess the relative risk of advanced stage at diagnosis (Stage IV), surgery for localized disease (Stage I/II), and cancer-specific mortality. RESULTS: There was no significant association of BIM or WIM on advanced stage at diagnosis in Black or White patients. An increase of $10,000 of BIM was associated with a 9% decrease in hazards of death for both Black (hazard ratio 0.91, 95% confidence interval 0.86,0.95) and White (0.91, 95%CI 0.90,0.93) patients, while the same increase in WIM was associated with no significant difference in hazards among Black patients (hazard ratio 0.99, 95% confidence interval 0.97,1.02). There were no predicted racial differences in hazards of death at high levels of BIM. CONCLUSIONS: Increased Black income mobility significantly improves survival for both Black and White patients. Interventions aimed at increasing economic and social mobility could significantly decrease mortality in both Black and White patients while alleviating disparities in outcomes.

OBJECTIVE: We sought to examine the impact of racial residential segregation on Black-White disparities in colorectal cancer diagnosis, surgical resection, and cancer-specific survival. SUMMARY BACKGROUND DATA: There are clear Black-White disparities in colorectal cancer diagnosis and treatment with equally disparate explanations for these findings, including genetics, socioeconomic factors, and health behaviors. METHODS: Data on Black and White patients with colorectal cancer were obtained from SEER between 2005 and 2015. The exposure of interest was the index of dissimilarity (IoD), a validated measure of segregation derived from 2010 Census data. Outcomes included advanced stage at diagnosis (AJCC stage IV), resection of localized disease (AJCC stage I-II), and cancer-specific survival. We used Poisson regression with robust error variance for the outcomes of interest and Cox proportional hazards were used to assess cancer-specific 5-year survival. RESULTS: Black patients had a 41% increased risk of presenting at advanced stage per IoD [risk ratio (RR) 1.41, 95% confidence intervals (CI) 1.18, 1.69] and White patients saw a 17% increase (RR 1.17, 95%CI 1.04, 1.31). Black patients were 5% less likely to undergo surgical resection (RR 0.95, 95%CI 0.90, 0.99), whereas Whites were 5% more likely (RR 1.05, 95%CI 1.03, 1.07). Black patients had 43% increased hazards of cancer-specific mortality with increasing IoD (hazard ratio (HR) 1.43, 95%CI 1.17, 1.74). CONCLUSIONS: Black patients with colorectal cancer living in more segregated counties are significantly more likely to present at advanced stage and have worse cancer-specific survival. Enduring structural racism in the form of residential segregation has strong impacts on the colorectal cancer outcomes.

OBJECTIVE: To understand the role of racial residential segregation on Black-White disparities in breast cancer presentation, treatment, and outcomes. SUMMARY OF BACKGROUND DATA: Racial disparities in breast cancer treatment and outcomes are well documented. Black individuals present at advanced stage, are less likely to receive appropriate surgical and adjuvant treatment, and have lower overall and stage-specific survival relative to White individuals. METHODS: Using data from the Surveillance, Epidemiology, and End Results program, we performed a retrospective cohort study of Black and White patients diagnosed with invasive breast cancer from 2005 to 2015 within the 100 most populous participating counties. The racial index of dissimilarity was used as a validated measure of residential segregation. Multivariable regression was performed, predicting advanced stage at diagnosis (stage III/IV), surgery for localized disease (stage I/II), and overall stage-specific survival. RESULTS: After adjusting for age at diagnosis, estrogen/progesterone receptor status, and region, Black patients have a 49% greater risk (relative risk [RR] 1.49 95% confidence interval [CI] 1.27, 1.74) of presenting at advanced stage with increasing segregation, while there was no observed difference in Whites (RR 1.04, 95% CI 0.93, 1.16). Black patients were 3% less likely to undergo surgical resection for localized disease (RR 0.97, 95% CI 0.95, 0.99) with increasing segregation, while Whites saw no significant difference. Black patients had a 29% increased hazard of death (RR 1.29, 95% CI 1.04, 1.60) with increasing segregation; there was no significant difference among White patients. CONCLUSIONS: Our data suggest that residential racial segregation has a significant association with Black-White racial disparities in breast cancer. These findings illustrate the importance of addressing structural racism and residential segregation in efforts to reduce Black-White breast cancer disparities.

BACKGROUND: Disparities in pancreatic cancer outcomes between black and white patients are well documented. This study aimed to use a more novel index to examine the impact of racial segregation on the diagnosis, management, and outcomes of pancreatic cancer in black patients compared with white patients. METHODS: Black and white adults with pancreatic cancer in urban counties were identified using data from the 2018 submission of the Surveillance, Epidemiology and End Results (SEER) Program and the 2010 Census. The racial index of dissimilarity (IoD), a validated proxy of racial segregation, was used to assess the evenness with which whites and blacks are distributed across census tracts in each county. Multivariate Poisson regression was performed, and stepwise models were constructed for each of the outcomes. Overall survival was studied using the Kaplan-Meier method. RESULTS: The study enrolled 60,172 adults with a diagnosis of pancreatic cancer between 2005 and 2015. Overall, the black patients (13.8% of the cohort) lived in more segregated areas (IoD, 0.67 vs 0.61; p < 0.05). They were less likely to undergo surgery for localized disease (relative risk [RR], 0.80; 95% confidence interval [CI], 0.76-0.83) and more frequently had a diagnosis of advanced-stage disease (RR, 1.09; 95% CI, 1.01-1.19) with increasing segregation. They also had shorter survival times (9.8 vs 11.4 months; p < 0.05). CONCLUSIONS: Disparities in advanced-stage disease at diagnosis, surgery for localized disease, and overall survival are directly related to the degree of residential segregation, a proxy for structural racism. In searching for solutions to this problem, it is important to account for the historical marginalization of black Americans.

OBJECTIVES: To examine the effects of racial residential segregation and structural racism on the diagnosis, treatment, and outcomes of patients with prostate cancer. PATIENTS AND METHODS: This retrospective cohort study examined men diagnosed with prostate cancer between 2005 and 2015. We collected data from Black and White men, aged ≥30 years, living within the 100 most populous counties participating in the Surveillance, Epidemiology, and End Results programme, a nationally representative dataset. The racial Index of Dissimilarity, a validated measure of segregation, was the primary exposure of interest. Outcomes of interest included advanced stage at diagnosis (Stage IV), surgery for localised disease (Stage I-II), and 10-year overall and cancer-specific survival. Multivariable Poisson regression analyses with robust error variance estimated the relative risk (RR) of advanced stage at diagnosis and surgery for localised disease at differing levels of segregation. Survival analysis was performed using competing hazards analysis. RESULTS: Multivariable models estimating stage at diagnosis showed that the disparities between Black and White men disappeared at low levels of segregation. Disparities in receiving surgery for localised disease persisted across all levels of segregation. In racially stratified analyses, segregation had no effect on stage at diagnosis or surgical resection for Black patients. White patients saw a 56% (RR 0.42, P < 0.001) reduced risk of presenting at advanced stage and 20% increased likelihood (RR 1.20, P < 0.001) of surgery for localised disease. Black patients in the lowest segregation areas had the lowest overall mortality, but the highest cancer-specific mortality. CONCLUSIONS: Our study provides evidence that residential segregation has a significant impact on Black-White disparities in prostate cancer, likely through improved outcomes for White patients and worse outcomes for Black patients in more segregated areas. These findings suggest that mitigating segregation and the downstream effects of socioeconomic factors could alleviate these disparities.

BACKGROUND: There is a long history of segregation in the U.S.A with enduring impacts on cancer outcomes today. We evaluated the impact of segregation on racial disparities in Hepatocellular Carcinoma (HCC) treatment and outcomes. METHODS: We obtained data on black and white patients with HCC from the SEER program (2005-2015) within the 100 most populous participating counties. Our exposure was the index of dissimilarity (IoD), a validated measure of segregation. Outcomes were overall survival, advanced stage at diagnosis (Stage III/IV) and surgery for localized disease (Stage I/II). Cancer-specific survival was assessed using Kaplan-Meier estimates. RESULTS: Black patients had a 1.18 times increased risk (95%CI 1.14,1.22) of presenting at advanced stage as compared to white patients and these disparities disappeared at low levels of segregation. In the highest quartile of IoD, black patients had a significantly lower survival than white (17 months vs 27 months, p < 0.001), and this difference disappeared at the lowest quartile of IoD. CONCLUSIONS: Our data illustrate that structural racism in the form racial segregation has a significant impact on racial disparities in the treatment of HCC. Urban and health policy changes can potentially reduce disparities in HCC outcomes.

BACKGROUND: Rural counties in the United States have higher firearm suicide rates and opioid overdoses than urban counties. We sought to determine whether rural counties can be grouped based on these "diseases of despair." METHODS: Age-adjusted firearm suicide death rates per 100,000; drug-related death rates per 100,000; homicide rate per 100,000, opioid prescribing rate, %black, %Native American, and %veteran population, median home price, violent crime rates per 100,000, primary economic dependency (nonspecialized, farming, mining, manufacturing, government, and recreation), and economic variables (low education, low employment, retirement destination, persistent poverty, and persistent child poverty) were obtained for all rural counties and evaluated with hierarchical clustering using complete linkage. RESULTS: We identified five distinct rural county clusters. The firearm suicide rates in the clusters were 5.9, 6.8, 6.4, 8.5, and 3.8 per 100,000, respectively. The counties in cluster 1 were poor, mining dependent, with population loss, cluster 2 were nonspecialized economies, with high opioid prescription rates, cluster 3 were manufacturing and government economies with moderate unemployment, cluster 4 were recreational economies with substantial veterans and Native American populations, high median home price, drug death rates, opioid prescribing, and violent crime, and cluster 5 were farming economies, with high population loss, low median home price, low rates of drug mortality, opioid prescribing, and violent crime. Cluster 4 counties were spatially adjacent to urban counties. CONCLUSIONS: More than 300 counties currently face a disproportionate burden of diseases of despair. Interventions to reduce firearm suicides should be community-based and include programs to reduce other diseases of despair.

BACKGROUND: Psychosocial data about living kidney donors have been collected for almost 5 decades now. To date, however, no study has provided any psychosocial follow-up of donors who developed a serious health problem such as end-stage renal disease (ESRD). METHODS: Donors who developed ESRD were invited to participate in a qualitative interview if they met one or both of the inclusion criteria: (1) developed ESRD within 10 years of donating and/or (2) lacked health insurance at the time of donation. We contacted 38 individuals who met these criteria, and 22 participated (58%). Two were subsequently excluded from analysis. RESULTS: Twenty qualitative interviews were analyzed. Five findings are described: (1) donors describe the decision-making process as spontaneous and fast; (2) donors describe lack of appreciation for the need for post-donation self-care; (3) donors do not regret donating despite the adverse outcome; (4) donors advise future donors to have in place emotional and physical support post donation; and (5) donors appreciate the opportunity to tell their story from being a living donor to living with ESRD, which virtually all perceive as 2 separate unrelated events. CONCLUSIONS: Most donors are positive about their donation decision and experience and would donate again, despite developing ESRD themselves. They propose some important changes to the decision-making and informed-consent processes. Our data are reassuring regarding lack of donor regret, but highlight the need for living donor transplant programs to ensure that living donors understand their long-term risks and receive appropriate life-long follow-up care to minimize these risks.

Importance: Black and other racially minoritized groups are overrepresented among those who experience firearm homicide. There has been a stark increase in incarcerated populations in the US since the 1980s, largely due to differential drug sentencing, of which racially minoritized individuals are also overrepresented; social disorganization theory postulates that community and family instability resulting from incarceration can further worsen crime. Objective: To understand the association of race-specific incarceration with race-specific firearm violence rates in Chicago, Illinois, through the lens of social vulnerability and family instability. Design, Setting, and Participants: This cross-sectional study with a retrospective cohort design utilized homicide data for the city of Chicago from January 1, 2001, to August 31, 2019. Demographic data at the census block level was obtained from the 2010 decennial census. Incarceration rates were obtained by race and ethnicity at the census tract level from the Opportunity Atlas. Data analysis occurred from January to June 2023. Exposure: Race-specific incarceration rates were the primary exposures of interest. The Social Vulnerability Index and single-parent households were studied as mediators. Main Outcomes and Measures: Race-specific firearm homicide rates were the outcomes of interest. Structural equation modeling was used to understand the mediating effect of social vulnerability and single-parent households on the association of incarceration with firearm homicides. Results: A total of 46â¯312 census blocks were evaluated. Black-specific incarceration rates were found to be associated with Black-specific firearm homicides (incidence rate ratio [IRR], 1.70; 95% CI, 1.50-1.94), but there was no association for Hispanic incarceration rates (IRR, 0.98; 95% CI, 0.75-1.28) or White incarceration rates (IRR, 1.13; 95% CI, 0.39-1.16). In the association of Black incarceration rates with Black firearm homicide rates, social vulnerability did not mediate the interaction, but the percentage of single-parent households mediated 23% of the interaction. Conclusions and Relevance: This study found that higher rates of incarceration were associated with increased rates of firearm homicides among Black communities alone; this association was found to be mediated partially through the density of single-parent households in these areas, suggesting that social disorganization resulting from mass incarceration may perpetuate firearm homicides. Targeted policies addressing mass incarceration and the disparities therein may be a means of reducing urban firearm homicides.

BACKGROUND: Gunshot wounds (GSWs) remain a significant source of mortality in the United States. Timely delivery of trauma care is known to be critical for survival. We sought to understand the relationship of predicted transport time and death after GSW. Given large racial disparities in firearm violence, we also sought to understand disparities in transport times and death by victim race, an unstudied phenomenon. METHODS: Firearm mortality data were obtained from the Boston Police Department 2005 to 2023. Firearm incidents were mapped using ArcGIS. Predicted transport times for each incident to the closest trauma center were calculated in ArcGIS. Spatial autoregressive models were used to understand the relationship between victim race, transport time to a trauma center, and mortality associated with the shooting incidents. RESULTS: There were 4,545 shooting victims with 758 deaths. Among those who lived, the median transport time was 9.4 minutes (interquartile range, 5.8-13.8) and 10.5 minutes (interquartile range, 6.4-14.6; p = 0.003) for those who died. In the multivariable logistic regression, increased transport time to the nearest trauma center (odds ratio, 1.024; 95% confidence interval, 1.01-1.04) and age (odds ratio, 1.016; 95% confidence interval, 1.01-1.02) were associated with mortality. There was a modest difference in median transport time to the nearest trauma center by race with non-Hispanic Black at 10.1 minutes, Black Hispanic 9.2 minutes, White Hispanic 8.5 minutes, and non-Hispanic White 8.3 minutes ( p < 0.001). CONCLUSION: Our results highlight the relationship of transport time to a trauma center and death after a GSW. Non-White individuals had significantly longer transport times to a trauma center and predicted mortality would have been lower with White victim transport times. These data underscore the importance of timely trauma care for GSW victims and can be used to direct more equitable trauma systems. LEVEL OF EVIDENCE: Prognostic/Epidemiological; Level III.

BACKGROUND: Colorectal cancer screening has been shown effective at reducing stage at presentation, but there is differential uptake of screening based on insurance status. We sought to determine the population-level effect of Medicare and screening guidelines on colorectal screening by race and region. METHODS: Data on Black and white patients with colorectal cancer were obtained from the SEER database. Regression discontinuity was used to assess the causal effect of near-universal health insurance (represented by age 65) and United States Preventive Services Task Force guidelines (age 50) on the proportion of people presenting at advanced stage. This was stratified by race and region. RESULTS: In the Southern United States, Black patients saw a significant decrease in advanced stage at presentation at age 65 (coefficient -0.12, pâ¯=â¯0.003), while white patients did not (coefficient -0.03, pâ¯=â¯0.09). At age 50, neither Black (coefficient 0.09, pâ¯=â¯0.10) nor white patients (coefficient -0.04, pâ¯=â¯0.1) saw a significant decrease in advanced stage. In the Western U.S., neither Black (coefficient 0.02, pâ¯=â¯0.72) or white patients (coefficient -0.02, pâ¯=â¯0.09) saw a significant decrease in advanced stage at age 65; however, both Black (coefficient -0.20, pâ¯=â¯0.008) and white patients (coefficient -0.05, pâ¯=â¯0.03) saw a significant decrease at age 50. CONCLUSIONS: Our data highlight the significant impact that near-universal insurance has on reducing colorectal cancer stage at presentation in areas with poor baseline insurance coverage, particularly for Black patients. To reduce disparities in advanced stage at presentation for colorectal cancer, state-level insurance coverage should be addressed.

BACKGROUND: Much of the recorded medical literature focuses on individual-level factors that contribute to firearm violence. Recently, studies have highlighted higher incidence of firearm violence in historically redlined and marginalized areas, but few have gone on to study the downstream associations causing these differences. This study aims to understand the effects of historic redlining and current income mobility on firearm violence. METHODS: Using a retrospective cross-sectional design, shooting incidents were spatially joined with redlining vector files and linked to income mobility data (how much a child makes in adulthood). Participants included all assault and homicide incidents involving a firearm in the city of Boston, between 2016 and 2019. The exposure of interest was redlining designation as outlined by the Home Owner's Loan Corporation (HOLC) in the 1930s and income mobility, stratified by race, defined as the income of a child in their 30s compared with where they grew up (census tract level). The outcome measured was shooting rate per census block. RESULTS: We find that increases in Black income mobility (BIM) and White income mobility (WIM) are associated with significant decreases in rates of firearm incidents in all HOLC designations; however, there is a larger decrease with increasing BIM (relative risk, 0.47 per unit increase in BIM [95% confidence interval, 0.35-0.64]; relative risk, 0.81 per unit increase in WIM [95% confidence interval, 0.71-0.93]). Plotting predicted rates of firearm violence in each HOLC designation at different levels of BIM, there were no significant differences in shooting rates between historically harmful and beneficial classifications above $50,000 of BIM. Despite level of WIM, there were continued disparities between harmful and beneficial HOLC classification. CONCLUSION: These findings highlight the importance of structural racism in the form of redlining and discriminatory housing policies, and the preclusion from economic mobility therein, on the incidence of firearm violence today. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

BACKGROUND: Firearm homicides disproportionately affect young Black men, which in turn have lasting impact of communities of color as a whole. Previous cross-sectional studies have highlighted the role of discriminatory housing policies on the incidence of urban firearm violence. We sought to estimate the effects of racist housing policies on firearm incidence. METHODS: Firearm incident data were obtained from the Boston Police Department and point locations spatially joined with vector files outlining the original 1930 Home Owner Loan Corporation (HOLC) Redlining maps. A regression discontinuity design was used to assess the increased rate of firearm violence crossing from historically "desirable" neighborhoods (Green) to historically "hazardous" neighborhoods (Red and Yellow) based on HOLC definitions. Linear regression models were fit on either side of the geographic boundaries with firearm incidents graphed at varying distances and the regression coefficient calculated at the boundary. RESULTS: Crossing from desirable to Red hazardous designation there was a significant discontinuity with an increase of 4.1 firearm incidents per 1,000 people (95% CI 0.68,7.55). Similarly, when crossing from desirable areas to the Yellow hazardous designation there was a significant discontinuity and increase of 5.9 firearm incidents per 1,000 people (95% CI 1.85,9.86). There was no significant discontinuity between the two hazardous HOLC designations (coefficient -0.93, 95% CI -5.71, 3.85). CONCLUSIONS: There is a significant increase in firearm incidents in historically redlined areas of Boston. This suggests that interventions should focus on downstream socioeconomic, demographic, and neighborhood detriments of historically discriminatory housing policies in order to address firearm homicides.

Research on health disparities in thoracic surgery is based on large population-based studies, which is associated with certain biases. Several methodological challenges are associated with these biases and warrant review and attention. The lack of standardized definitions in health disparities research requires clarification for study design strategy. Further inconsistencies remain when considering data sources and collection methods. These inconsistencies pose challenges for accurate and standardized downstream data analysis and interpretation. These sources of bias should be considered when establishing the infrastructure of health disparities research in thoracic surgery, which is in its infancy and requires further development.

BACKGROUND: Firearm injury remains a major cause of morbidity and mortality in the United States. Because of prior lack of comprehensive data sources, there is a paucity of literature on nonfatal firearm injury. Associations have previously been shown between state-level firearm laws and firearm fatalities, but few studies have examined the effects of these laws on nonfatal firearm hospitalization rates. Our objective was to examine the relationship between state firearm laws and firearm injury-related hospitalization rates across all 50 states over a 17-year period. METHODS: In this panel study design, we used fixed effects multivariate regression models to analyze the relationship between 12 laws and firearm state-level injury-related hospitalization rates from 2000 to 2016 using the RAND Corporation Inpatient Hospitalizations for Firearm Injury Database. We used difference-in-differences to determine the impact of law passage in a given state compared with those states without the law, controlling for state-level covariates. The main outcome measure was the change in annual firearm injury-related inpatient hospitalization rates after passage or repeal of a state-level firearm law. RESULTS: Examining each law individually, passage of violent misdemeanor, permitting, firearm removal from domestic violence offenders, and 10-round limit laws were associated with significant firearm injury-related hospitalization rate reductions. Examining multiple laws in the same model, passage of violent misdemeanor laws was associated with a 19.9% (confidence interval, 11.6%-27.4%) reduction, and removal of firearms from domestic violence offenders was associated with a 17.0% (confidence interval, 9.9%-23.6%) reduction in hospitalization rates. CONCLUSION: State laws related to preventing violent offenders from possessing firearms are associated with firearm injury-related hospitalization rate reductions. Given significant physical, mental, and social burdens of nonfatal firearm injury, determining the efficacy of firearm-related policy is critical to violence and injury prevention efforts. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level IV.
