Introduction: A disparity in health outcomes between black and white patients with coronary artery disease (CAD) has also been reported with pathophysiological differences in CAD and racial disparities in providing health care as potential explanations. Hypothesis: To determine racial disparity in emergency care of patients with suspected acute coronary syndrome (ACS) undergoing cardiac CT angiography (cCTA), which provides knowledge of underlying CAD status. Methods: We combined patient level data of the ACRIN-PA 4005 (American College of Radiology Imaging Network, Pennsylvania) and ROMICAT II (Rule Out Myocardial Infarction using Computer Assisted Tomography) trials, which enrolled patients presenting with suspicion of ACS who were randomized to cCTA as a first diagnostic test at 14 US sites. Sample was restricted to subjects with known CAD status based on cCTA. Self-reported race while the race ‘Black’ were defined as “a person having origins in any of the black racial groups of Africa” and the race ‘white’ as “a person having origins in any of the original peoples of Europe, the Middle East, or North Africa”. Results: We included 1,191 patients (53% white, 47% black). Pretest probability for ACS was similar (TIMI score, p=0.77) between black and white patients, while black patients had lower presence and extent of CAD (calcium score: 39.3±189.3 vs. 88.2±292.1, p<0.001; obstructive CAD 8.3% vs. 17.5%, p<0.001) and ACS (4.0% vs 6.9%, p=0.03). After accounting for the underlying CAD, black patients were more likely admitted to the hospital (β: 0.29 [95%CI: 0.05-0.54-]) and were more likely to undergo additional testing (β: 0.47 [95%CI: 0.09-0.85]) while remaining management showed no significant differences. Conclusions: After adjustment for underlying CAD, among patients in the ED with suspicion of ACS, those who are black received more downstream testing and were more frequently admitted to hospital than white patients.

Objectives: Several clinical studies have outlined differences in clinical outcomes and access to care when controlling for race. No published clinical study has ever investigated healthcare disparities between Black and White patients presenting for sports medicine knee surgery. The purpose of this study is to determine if the racial disparities described in the literature for total joint arthroplasty and spine surgery are also preset in patients presenting for sports medicine knee surgery. Our first hypothesis is that Black patients presenting for sports medicine knee surgery have worse baseline patient-reported quality of life scores, pain, and function compared to White patients. Our second hypothesis is that Black patients have more disease severity at the time of surgery compared to their White counterparts. Methods: We prospectively collected patient-reported outcomes (PROs), disease severity, and treatment utilizing the [BLINDED DATABASE]. Patient race, body mass index (BMI) and insurance were retrospectively collected from the electronic medical record (EMR). We included consecutive patients undergoing both knee arthroscopy (partial meniscectomy) and anterior cruciate ligament (ACL) reconstruction surgery. We excluded patients undergoing other chondral replacement or complex ligamentous procedures (e.g. MPFL reconstruction, multiligamentous knee surgery, etc). Univariate ("unadjusted") analysis was utilized to compare differences between groups with ANOVA, Kruskal Wallis Testing and Pearson’s Chi-square testing. Subsequently, a multivariate analysis model was constructed to control for confounding variables within Black patients vs White patients in order to evaluate for racial disparities in baseline PROs and disease severity. All testing was considered significant at the 5% level. Results: We enrolled a total of 4,557 patients for this study. In the arthroscopy group (APM) we enrolled 3086 total patients. In this group there were 2593 White patients and 408 Black patients. Eighty-five patients identified as “Other”. In the ACL reconstruction (ACLR) group there were 1471 patients. In this group 1197 patients identified as White, 202 patients identified as Black and 72 patients identified as “Other”. Univariate analysis in the APM group demonstrated racial disparities in certain key metrics. BMI was worse in Black patients (32.4) compared to White patients (30.3) (p < 0.001). Both KOOS pain (41.7 versus 47.2; p < 0.001) and KOOS function (51.5 versus 58.0; p < 0.001) were worse in Black patients compared to White patients. A larger portion of Black patients were current smokers compared to White patients (16.% versus 10%; p < 0.001). Baseline VR12 scores were also lower in Black versus White patients (48.4 versus 55.9, p 0.001). Multivariate analysis revealed no racial disparities for any baseline patient-reported outcome measure (pain, function, or quality of life). This is a result of Black patients being more likely to present with higher BMI, current smoker status, fewer years of formal education, and Medicaid insurance. No significant differences between Black and White patients were noted with respect to disease severity (intraoperative pathology; i.e. worse chondral grade, compartments involved, meniscus tear severity). Our ACLR group demonstrated similar findings on univariate analysis with Black patients more likely to have Medicare/Medicaid than commercial insurance, a higher BMI, smoking history and a lower VR12 score compared to White patients. Linear regression analysis demonstrates that age, gender (female worse), BMI, years of education, smoking status and insurance are all significant drivers of outcome for KOOS pain. With respect to additional intra-articular pathology at the time of ACL tear, female sex and increasing years of education were at an increased odds of having a complete meniscal tear. Neither race or insurance status were significant drivers of concomitant intra-articular findings in ACL tear patients. Conclusions: There is no statistically significant racial disparity in baseline patient reported outcomes with respect to patients presenting for sports medicine knee surgery when controlling for important covariates. Black patients did present with worse subjective KOOS knee pain and functional scores, however, when possible confounding variables were controlled for in a multivariable analysis, there was no difference between the White and Black cohorts. The results of this study show that there may be modifiable risk factors that affect outcomes of patients irrespective of racial background. Addressing factors such as BMI, smoking status and healthcare literacy may help to improve outcomes for patients. Further research into interventions to correct these risk factors is needed.

6533 Background: Equity is now recognized as an essential aspect of health care quality. Racial inequities in clinical performance diminish overall system performance. We assessed the feasibility and reliability of practice-level measures of racial disparities in chemotherapy-associated emergency department (ED) visits and hospitalizations. Methods: Using fee-for-service Medicare data, we identified 1,196,970 Black or White fee-for-service Medicare beneficiaries with cancer receiving chemotherapy in 2016-2019, who were attributed to 5511 oncology practices that treated at least 1 Black and 1 White beneficiary (96.4% of all beneficiaries). We studied two CMS quality measures: chemotherapy associated ED visits and chemotherapy associated hospitalizations. For each outcome, we estimated multi-level models with separate practice-level random intercepts for Black and White patients to quantify practice-level Black-White disparities in adjusted rates of these measures and assess the associations of these rates with the proportion of Black patients in the practice. Results: Overall, 108,177 Black and 966,381 White beneficiaries with cancer were treated at 1321 practices with reliable estimates (reliability ≥70%) of Black-White differences in rates of chemotherapy-associated ED visits; 101,411 Black and 915,895 White beneficiaries were treated at 1,012 practices with reliable estimates of chemotherapy-associated hospitalizations. These practices treated 80% or more of all Black and White beneficiaries; 10% of these practices treated 75% of Black beneficiaries. The median adjusted Black-White rate difference across practices was +8.9% [interquartile interval (IQI) +5.0%, +12.8%; 5th, 95th percentile -1.8 to +19.2%] for chemotherapy associated ED visits and +4.4% [IQI +1.3%, +7.7%; 5th, 95th percentile -3.5% to +13.5%] for chemotherapy associated hospitalizations. Chemotherapy-associated ED visit rates were 3.2 percentage points higher for Black vs White patients (P <.001) at the practice with the mean % of Black patients, but the difference was smaller in practices with more Black patients (0.4 percentage points less for each 10% increase in Black share, P <.001). Chemotherapy-associated hospitalization rates were 0.6 percentage points lower for Black vs White patients (P =.01) but did not vary by practice racial composition. Conclusions: Using data from more than 1000 practices over 4 years, we calculated reliable estimates of practice-level racial disparities in chemotherapy-associated ED visits and hospitalizations. Practice-level performance for these quality measures was generally lower for Black versus White beneficiaries. Measuring and providing feedback on practice-level Black-White disparities in oncology performance measures may be one effective tool for advancing racial equity in care quality for cancer patients receiving chemotherapy.

101 Background: Racial disparities are well described in the management of early-stage lung cancer, with Black patients less likely to receive potentially curative surgery than non-Hispanic Whites. A multi-site pragmatic trial entitled Accountability for Cancer Care through Undoing Racism and Equity (ACCURE), designed in collaboration with community partners, eliminated racial disparities in lung cancer surgery through a multi-component intervention. The study involved real-time electronic health record (EHR) monitoring to identify patients not receiving recommended care, a nurse navigator who reviewed and addressed EHR alerts daily, and race-specific feedback provided to clinical teams. Timeliness of cancer care is an important quality metric. Delays can lead to disease progression, upstaging, and worse survival, and Black patients are more likely to experience longer wait times to lung cancer surgery. Yet interventions to reduce racial disparities in timely delivery of lung cancer surgery have not been well studied. We evaluated the effect of ACCURE on timely receipt of lung cancer surgery. Methods: We analyzed data of a retrospective cohort at five cancer centers gathered prior to the ACCURE intervention and compared results with prospective data collected during the intervention. We calculated mean time from clinical suspicion of lung cancer to surgery and evaluated the proportion of patients who received surgery within 60 days stratified by race. We performed a t-test to compare mean days to surgery and chi2 for the delivery of surgery within 60 days. Results: 1320 patients underwent surgery in the retrospective arm, 160 were Black. 254 patients received surgery in the intervention arm, 85 were Black. Results are summarized in Table. Mean time to surgery in the retrospective cohort was 41.8 days, compared with 25.5 days in the intervention cohort (p<0.01). In the retrospective cohort, 68.8% of Black patients received surgery within 60 days versus 78.9% of White patients (p<0.01). In the intervention, the difference between Blacks and Whites with respect to surgery within 60 days was no longer significant (89.41% of Black patients vs 94.67% of White patients, p=0.12). Conclusions: Racial disparities exist in the delivery of timely lung cancer surgery. The ACCURE intervention improved time to surgery and timeliness of surgery for Black and White patients with early-stage lung cancer. A combination of real-time EHR monitoring, nurse navigation, and race-based feedback markedly reduced racial disparities in timely lung cancer care. [Table: see text]

9005 Background: Cancer racial disparities may exist at many levels in the health care system, from screening to timely diagnosis and treatments received, as well as clinical trial enrollment. This study investigated differences in black versus white race among patients with NSCLC undergoing biomarker testing and clinical trial enrollment in the US. Methods: This retrospective observational study utilized the Flatiron Health database, which includes longitudinal data of patients with advanced/metastatic NSCLC. Patients were eligible if they had evidence of systemic therapy in the database from 1/1/2017 through 10/30/2020. Descriptive analyses summarized differences by race in biomarker testing and trial enrollment. Multivariable regression examined the relationship between these factors. Results: A total of 14,768 patients were eligible: 9,793 (66.3%) were white and 1,288 (8.7%) were black. 76.4% of white patients and 73.6% of black patients underwent at least one single molecular test or comprehensive genomic analysis (p = 0.03). Next-generation sequencing (NGS) was performed among 50.1% of white patients and 39.8% of black patients (p < 0.0001. Trial participation was observed among 3.9% of white and 1.9% of black patients (p = 0.0002). There was a statistically significant association between race (white vs black) and both biomarker testing (ever vs never) and trial participation (yes vs no) (both p < 0.001, unadjusted chi square). Differences in NGS testing, baseline biomarker testing, and race were retained as statistically significant (p < 0.01) in adjusted regression analyses. The receipt of first-line targeted therapy was comparable between white and black patients (10.2% and 9.2%, respectively, p = 0.24); however, this summary did not consider biomarker test results. First line use of pembrolizumab+carboplatin+pemetrexed was observed among 19.8% of white and 22.6% of black patients; carboplatin+paclitaxel was observed among 16.5% and 18.6%, and single-agent pembrolizumab was observed among 14.8% and 11.5%, respectively. Conclusions: The use of NGS-based testing, which is recommended by the National Comprehensive Cancer Network Clinical Guidelines in Oncology for patients with advanced/metastatic NSCLC, is the most notable disparity among black patients, with more than a 10 percentage-point difference in receipt of this testing versus white counterparts. This may in part contribute to the more than double the rate of participation in clinical trials observed among white patients, as many second line and beyond trials utilize molecular targets as inclusion criteria. While multiple factors are known to impact health care disparities, access to and receipt of appropriate biomarker testing may be an attenable goal in order to ensure equal access to quality care.

Background: Due to increased risks of contrast nephropathy, chronic kidney disease (CKD) can deter consideration of invasive management for patients with myocardial infarction (MI). Black patients have a higher prevalence of CKD. Whether racial disparities exist in the use of invasive MI management for patients with CKD presenting with MI is unknown. Methods: We examined 717 012 White and 99 882 Black patients with MI treated from 2008 to 2017 at 914 hospitals in the National Cardiovascular Data Registry Chest Pain—MI Registry. CKD status was defined as estimated glomerular filtration rate (eGFR) ≥90 mL/(min·1.73 m 2 ; no CKD), eGFR <90 but ≥60 (mild), eGFR <60 but ≥30 (moderate), and eGFR <30 or dialysis (severe). We used multivariable logistic regression models to examine the interaction of race and CKD severity in invasive MI management. Results: Among those with MI, Black patients were more likely than White patients to have CKD (eGFR <90; 61.4% versus 58.5%; P <0.001). Among those with MI and CKD, Black patients were more likely than White patients to have severe CKD (21.2% versus 12.4%; P <0.001). Patients with CKD were more likely than those without CKD to have diabetes or heart failure; Black patients with CKD were more likely to have these comorbidities when compared with White patients with CKD (all P <0.0001). Black race and CKD were associated with a lower likelihood of invasive management (adjusted odds ratio, 0.78 [95% CI, 0.75–0.81]; adjusted odds ratio, 0.72 [95% CI, 0.70–0.74]; P <0.001 for both). At eGFR levels ≥10, Black patients were significantly less likely than White patients to undergo invasive management. Conclusions: Black patients with MI and mild or moderate CKD were less likely to undergo invasive management compared with White patients with similar CKD severity. National efforts are needed to address racial disparities that may remain in the invasive management of MI.
