Abstract
The Sars coronavirus 2019 (COVID-19) pandemic has resulted in increased morbidity and mortality; however, there is limited understanding of how excess mortality is distributed among different racial and ethnic subgroups and vascular diseases. METHODS We conducted a retrospective, cross-sectional study design using data from the United States (US) Center for Disease Control (CDC) Wide Ranging Online Data for Epidemiologic Research (Wonder) database. The database contains death certificate information for all US residents by cause of death as ascertained by the treating physician. We examined the trends of excess death by vascular disease specific mortality among different racial and ethnicity subgroups. Excess deaths were defined as the difference between observed numbers of deaths in specific time periods and the expected numbers of deaths in the same time periods. We compared mortality rates during the reference period of 2018-2019 (pre-pandemic) with the study period of 2020-2021 (pandemic years). We also compared excess mortality rates among racial and ethnic subgroups (Non-Hispanic white, Non-Hispanic Black, and Hispanic individuals). Vascular disease was categorized by administrative diagnostic codes (ICD10): Vascular disease (I26, I82, I70-73, I74) and its subtypes Arterial thrombosis (I74), venous thromboembolism (I26, I82) and atherosclerotic disease (I70-73). RESULTS Compared to 2018-2019, there was a 1.3 % excess mortality associated with vascular disease, a 12.2 % excess mortality due to arterial thrombosis mortality, and an 8.0 % excess mortality due to thromboembolism in 2020-2021. Black individuals demonstrated higher excess vascular mortality (6.9 %) compared to white individuals (-0.3 %) P < .001, higher excess venous thromboembolism mortality (14.1 % vs 5.1 % P = 0.002) and higher atherosclerosis mortality (2.1 % vs -2.6 % P = 0.002). Hispanics compared to white individuals had higher excess vascular mortality (5.1 % vs -0.3 % P = 0.03) and excess venous thromboembolism mortality (24.2 % vs 5.1 % P < 0.001). CONCLUSION The COVID-19 pandemic has led to a significant and persistent increase in vascular mortality. Excess mortality has disproportionately affected Black and Hispanic individuals compared to white individuals, highlighting the need for further studies to address and eliminate these health care disparities.

Evaluating Receipt of Optimal Medical Therapy Amongst Structurally Disadvantaged Groups Undergoing Amputation. Ann Vasc Surg 2024:S0890-5096(24)00561-2. [PMID: 39343377 DOI: 10.1016/j.avsg.2024.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 06/30/2024] [Accepted: 08/29/2024] [Indexed: 10/01/2024]
Abstract
OBJECTIVES Optimal medical therapy (OMT) for peripheral artery disease (PAD) is associated with decreased major amputation and mortality. OMT has several components, including antiplatelet and high-intensity statin therapy, blood pressure control, etc. While there are disparities in receipt of OMT among PAD patients, it is unknown if patients from disadvantaged neighborhoods, measured by the area deprivation index (ADI), are less likely to be on OMT. METHODS We performed a retrospective review of patients that underwent major lower extremity amputation between 2015 and 2019 at two large academic healthcare systems. Primary exposure was high ADI, defined as ADI ≥60th percentile, and secondary exposure was non-Hispanic Black (NHB) race. For each analysis, the primary outcome of interest was receipt of OMT, defined here as at least one antiplatelet agent and a high-intensity statin. The exposure outcome relationship was assessed using multivariable logistic regression. RESULTS Among 354 patients with median age of 66 (interquartile range [IQR] 58-74), 267 (75.4%) were male, 219 (61.9%) identified as NHB and 116 (32.8%) as non-Hispanic White. Overall, 91 (25.7%) patients were on OMT at time of amputation despite 57.3% of the cohort being established with a vascular surgeon. Compared to those with low ADI, the category high ADI had a higher proportion of NHB patients (48.1% vs 70.3%, p= 0.001) and patients were more often hospitalized at the University-affiliated facilities (47.4% vs 63.0%, p= 0.004). High ADI was not associated with receipt of OMT prior to major amputation (adjusted odds ratio [aOR] 0.72, 95% confidence interval [CI] 0.42-1.24). In secondary analysis, NHB race was not associated with receipt of OMT. Stratification by facility type (Veterans Affairs and University-affiliated facilities) also showed no association between high ADI or race and receipt of OMT. CONCLUSIONS Neighborhood economic well-being is not associated with receipt of OMT prior to major amputation. While the absence of socioeconomic disparities is notable, the proportion of patients on OMT is suboptimal. Care processes should be critically evaluated and quality measures potentially created to improve the rate of receipt of OMT among patients at risk for amputation.

Co-Morbidity Differences Associated With Long-Term Amputation and Repeat Revascularization Rates After Femoropopliteal Artery Intervention for Intermittent Claudication by Sex, Race, and Ethnicity. Am J Cardiol 2024; 226:40-49. [PMID: 38834142 DOI: 10.1016/j.amjcard.2024.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 04/29/2024] [Accepted: 05/11/2024] [Indexed: 06/06/2024]
Abstract
Use of peripheral vascular intervention (PVI) for intermittent claudication (IC) continues to expand, but there is uncertainty whether baseline demographics, procedural techniques and outcomes differ by sex, race, and ethnicity. This study aimed to examine amputation and revascularization rates up to 4 years after femoropopliteal (FP) PVI for IC by sex, race, and ethnicity. Patients who underwent FP PVI for IC between 2016 and 2020 from the PINC AI Healthcare Database were analyzed. The primary outcome was any index limb amputation, assessed by Kaplan-Meier estimate. Secondary outcomes included index limb major amputation, repeat revascularization, and index limb repeat revascularization. Unadjusted and adjusted hazard ratios (HRs) were estimated using Cox proportional hazard regression models. This study included 19,324 patients with IC who underwent FP PVI, with 41.2% women, 15.6% Black patients, and 4.7% Hispanic patients. Women were less likely than men to be treated with atherectomy (45.1% vs 47.8%, p = 0.0003); Black patients were more likely than White patients to receive atherectomy (50.7% vs 44.9%, p <0.001), and Hispanic patients were less likely than non-Hispanic patients to receive atherectomy (41% vs 47%, p = 0.0004). Unadjusted rates of any amputation were similar in men and women (6.4% for each group, log-rank p = 0.842), higher in Black patients than in White patients (7.8% vs 6.1%, log-rank p = 0.007), and higher in Hispanic patients than in non-Hispanic patients (8.8% vs 6.3%, log-rank p = 0.031). After adjustment for baseline characteristics, Black race was associated with higher rates of repeat revascularization (adjusted HR 1.13, 95% confidence interval 1.04 to 1.22) and any FP revascularization (adjusted HR 1.10, 95% confidence interval 1.01 to 1.20). No statistical difference in amputation rate was observed among comparison groups. Women and men with IC had similar crude and adjusted amputation and revascularization outcomes after FP PVI. Black patients had higher repeat revascularization and any FP revascularization rates than did White patients. Black and Hispanic patients had higher crude amputation rates, but these differences were attenuated by adjustment for baseline characteristics. Black patients were more likely to receive atherectomy and had higher rates of any repeat revascularization and specifically FP revascularization. Further study is necessary to determine whether these patterns are related to disease-specific issues or practice-pattern differences among different populations.

Abstract
INTRODUCTION Significant health inequalities in major adverse limb events exist. Ethnically minoritized groups are more prone to have a major adverse event following peripheral vascular interventions. This systematic review and meta-analysis aimed to describe the postoperative implications of racial and ethnic status on clinical outcomes following vascular interventions for claudication and chronic limb-threatening ischemia. METHODS Searches were conducted across seven databases from inception to June 2021 and were updated in October 2022 to identify studies reporting claudication or chronic limb-threatening ischemia in patients who underwent open, endovascular, or hybrid procedures. Studies with documented racial and ethnic status and associated clinical outcomes were selected. Extracted data included demographic and clinical characteristics, vascular interventions, and measured outcomes associated with race or ethnicity. Meta-analyses were performed using random-effect models to report pooled odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Seventeen studies evaluating the impact of Black versus White patients undergoing amputation as a primary intervention were combined in a meta-analysis, revealing that Black patients had a higher incidence of amputations as a primary intervention than White patients (OR: 1.91, 95% CI: 1.61-2.27). Another meta-analysis demonstrated that Black patients had significantly higher rates of amputation after revascularization (OR: 1.56, 95% CI: 1.28-1.89). Furthermore, multiple trends were demonstrated in the secondary outcomes evaluated. CONCLUSIONS Our findings suggest that Black patients undergo primary major amputation at a significantly higher rate than White patients, with similar trends seen among Hispanic and First Nations patients. Black patients are also significantly more likely to be subjected to amputation following attempts at revascularization when compared to White patients.

Abstract
Background Implicit bias can influence behavior and decision-making. In clinical settings, implicit bias may influence treatment decisions and contribute to health disparities. Given documented Black-White disparities in vascular care, the purpose of this study was to examine the prevalence and degree of unconscious bias and awareness of bias among vascular surgeons treating peripheral artery disease (PAD). Methods The sampling frame included all vascular surgeons who participate in the Vascular Quality Initiative (VQI). Participants completed a survey which included demographic questions, the race implicit association test (IAT) to measure magnitude of unconscious bias, and six bias awareness questions to measure conscious bias. The magnitude of unconscious bias was no preference; or slight, moderate, or strong in the direction of pro-White or pro-Black. Data from participants were weighted to account for nonresponse bias and known differences in the characteristics of surgeons who chose to participate compared to the full registry. We stratified unconscious and conscious findings by physician race/ethnicity, physician sex, and years of experience. Finally, we examined the relationship between unconscious and conscious bias. Results There were 2,512 surgeons in the VQI registry, 304 of whom completed the survey, including getting IAT results. Most participants (71.6%) showed a pro-White bias with 73.0% of this group in the moderate and strong categories. While 77.5% of respondents showed conscious awareness of bias, of those whose conscious results showed lack of awareness, 67.8% had moderate or strong bias, compared to 55.7% for those with awareness. Bias magnitude varied based on physician race/ethnicity and years of experience. Women were more likely than men to report awareness of biases and potential impact of bias on decision-making. Conclusions Most people have some level of unconscious bias, developed from early life reinforcements, social stereotypes, and learned experiences. Regarding health disparities, however, these are important findings in a profession that takes care of patients with PAD due to heavy burden of comorbid conditions and high proportion of individuals from structurally vulnerable groups. Given the lack of association between unconscious and conscious awareness of biases, awareness may be an important first step in mitigation to minimize racial disparities in healthcare.

Abstract
Racial, ethnic, and socioeconomic disparities in the major risk factors for vascular disease and access to vascular specialist care are well-documented.1-3 The higher incidence of diabetes, peripheral artery disease (PAD), and related nontraumatic lower extremity amputation among racial and ethnic minority groups, those of low socioeconomic status, and those with poor access to care based on geography (together, referred to below as disadvantaged groups) are particularly pervasive.1,4-9 Practitioners of vascular surgery and endovascular therapy are uniquely positioned to address health inequities in lower extremity screening, medical management, intervention, and limb preservation among the population of adults at the highest risk for limb loss.

Abstract
BACKGROUND Non-Hispanic Black and Hispanic patients with symptomatic PAD may receive different treatments than White patients with symptomatic PAD. The delivery of guideline-directed medical treatment may be a modifiable upstream driver of race and ethnicity-related disparities in outcomes such as limb amputation. The purpose of our study was to investigate the prescription of preoperative antiplatelets and statins in producing disparities in the risk of amputation following revascularization for symptomatic peripheral artery disease (PAD). METHODS We used data from the Vascular Quality Initiative, a vascular procedure-based registry in the United States (2011-2018). We estimated the probability of preoperative antiplatelet and statin prescriptions and 1-year incidence of amputation. We then estimated the amputation risk difference between race/ethnicity groups that could be eliminated under a hypothetical intervention. RESULTS Across 100,579 revascularizations, the 1-year amputation risk was 2.5% (2.4%, 2.6%) in White patients, 5.3% (4.9%, 5.6%) in Black patients, and 5.3% (4.7%, 5.9%) in Hispanic patients. Black (57.5%) and Hispanic patients (58.7%) were only slightly less likely than White patients (60.9%) to receive antiplatelet and statin therapy. However, the effect of antiplatelets and statins was greater in Black and Hispanic patients such that, had all patients received these medications, the estimated risk difference comparing Black to White patients would have reduced by 8.9% (-2.9%, 21.9%) and the risk difference comparing Hispanic to White patients would have been reduced by 17.6% (-0.7%, 38.6%). CONCLUSION Even though guideline-directed care appeared evenly distributed by race/ethnicity, increasing access to such care may decrease health care disparities in major limb amputation.

Abstract
Comprehensively managing vascular disease in the United States can seem overwhelming. Vascular surgery providers encounter daily stress-inducing challenges, including caring for sick patients who often, because of healthcare barriers, struggle with access to care, socioeconomic challenges, and a complex medical system. These individuals can present with advanced disease and comorbidities, and many have limited treatment options. Subsequently, it could seem as if the vascular surgeon's efforts have little opportunity to make a difference. This review describes a method to counter this sentiment through directed action, hope, and community building. Vascular surgeons are passionate about what they do and are built to fight healthcare disparities. This review also outlines the reasoning for attempting to create change and one approach to begin making a difference.

Abstract
Disparities by sex, race, socioeconomic status, and geography exist in diagnosis, treatment, and outcomes for people with lower extremity peripheral artery disease (PAD). PAD prevalence is similar in men and women, but women have more atypical symptoms and undergo lower extremity revascularization at older ages compared to men. People who are Black have an approximately 2-fold higher prevalence of PAD, compared to people who are White and have more atypical symptoms, greater mobility loss, less optimal medical care, and higher amputation rates. Although fewer data are available for other races, people with PAD who are Hispanic have higher amputation rates than White people. Rates of amputation also vary by geography in the United States, with the highest rates of amputation in the southeastern United States. To improve PAD outcomes, intentional actions to eliminate disparities are necessary, including clinician education, patient education with culturally appropriate messaging, improved access to high-quality health care, science focused on disparity elimination, and health policy changes.

Abstract
Despite the universal healthcare coverages, racial disparities in healthcare expenditures among senior Medicare beneficiaries exist. A few studies explored how racial disparities in healthcare expenditures changed over past decades and how it affected differently across 4 minoritized races, by type of Medicare and poverty levels. We conducted a longitudinal study of 21 healthcare expenditures from senior Medicare fee-for-service enrollees to determine overall and secular trends in racial disparities in healthcare expenditures between 2007 and 2020, during which the Affordable Care Act (ACA) came into full force and the COVID-19 pandemic had begun. We found important disparities in healthcare expenditures across 4 minoritized races compared to Whites, even after adjusting for possible confounders for such disparities. Disparities between Hispanics/Asians and Whites were much greater than disparities between Blacks and Whites, in all Parts A, B, and D expenditures. This reality has not been sufficiently emphasized in the literature. Importantly, Black-White disparities in total Part B expenditure gradually worsened between 2007 and 2020, and Hispanic-White and Asian-White disparities worsened greatly during that time window. Health planners need to focus on these large disparities and develop methods to shrink them.

Abstract
Several studies have shown that women and racial and ethnic minority patients are at increased risk of developing lower extremity peripheral artery disease and suffering adverse outcomes from it, but a knowledge gap remains regarding the underlying causes of these increased risks. Both groups are more likely to be underdiagnosed, have poorly managed contributory comorbidities, and incur disparities in treatment and management postdiagnosis. Opportunities for improvement in the care of women and racial and ethnic minorities with peripheral artery disease include increased rates of screening, higher rates of clinical suspicion (particularly in the absence of typical symptoms of intermittent claudication), and more aggressive risk factor management before and after the diagnosis of peripheral artery disease.

Abstract
OBJECTIVE To evaluate the potential pathway, through which race and socioeconomic status, as measured by the social deprivation index (SDI), affect outcomes after lower extremity bypass chronic limb-threatening ischemia (CLTI), a marker for delayed presentation. BACKGROUND Racial and socioeconomic disparities persist in outcomes after lower extremity bypass; however, limited studies have evaluated the role of disease severity as a mediator to potentially explain these outcomes using clinical registry data. METHODS We captured patients who underwent lower extremity bypass using a statewide quality registry from 2015 to 2021. We used mediation analysis to assess the direct effects of race and high values of SDI (fifth quintile) on our outcome measures: 30-day major adverse cardiac event defined by new myocardial infarction, transient ischemic attack/stroke, or death, and 30-day and 1-year surgical site infection (SSI), amputation and bypass graft occlusion. RESULTS A total of 7077 patients underwent a lower extremity bypass procedure. Black patients had a higher prevalence of CLTI (80.63% vs 66.37%, P < 0.001). In mediation analysis, there were significant indirect effects where Black patients were more likely to present with CLTI, and thus had increased odds of 30-day amputation [odds ratio (OR): 1.11, 95% CI: 1.068-1.153], 1-year amputation (OR: 1.083, 95% CI: 1.045-1.123) and SSI (OR: 1.052, 95% CI: 1.016-1.089). There were significant indirect effects where patients in the fifth quintile for SDI were more likely to present with CLTI and thus had increased odds of 30-day amputation (OR: 1.065, 95% CI: 1.034-1.098) and SSI (OR: 1.026, 95% CI: 1.006-1.046), and 1-year amputation (OR: 1.068, 95% CI: 1.036-1.101) and SSI (OR: 1.026, 95% CI: 1.006-1.046). CONCLUSIONS Black patients and socioeconomically disadvantaged patients tended to present with a more advanced disease, CLTI, which in mediation analysis was associated with increased odds of amputation and other complications after lower extremity bypass compared with White patients and those that were not socioeconomically disadvantaged.

Five Year Survival in Medicare Patients Undergoing Interventions for Peripheral Arterial Disease: a Retrospective Cohort Analysis of Linked Registry Claims Data. Eur J Vasc Endovasc Surg 2023; 66:541-549. [PMID: 37543356 DOI: 10.1016/j.ejvs.2023.07.055] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 06/19/2023] [Accepted: 07/31/2023] [Indexed: 08/07/2023]
Abstract
OBJECTIVE To justify the up front risks of offering elective interventions for intermittent claudication (IC), patients should have reasonable life expectancy to derive durable clinical benefits. Open surgery for chronic limb threatening ischaemia (CLTI) is maximally beneficial in patients surviving ≥ 2 years. The aim was to assess long term survival after IC and CLTI interventions. METHODS In a retrospective cohort analysis, the Vascular Quality Initiative (VQI) registry from 1 January 2010 to 31 May 2021 was queried for peripheral vascular intervention (PVI), infra-inguinal bypasses (IIB), and supra-inguinal bypasses (SIB) for IC and CLTI across 286 US centres. VQI linkage to Medicare insurance claims provided five year survival data. Multivariable analysis identified factors associated with five year mortality. RESULTS There were 31 457 PVIs (44.7% IC, 55.3% CLTI), 7 978 IIBs (26.9% IC, 73.1% CLTI), and 2 149 SIBs (50.1% IC, 49.9% CLTI) recorded in the VQI. Among the PVI, IIB, and SIB cohorts, average ages were 75, 73, and 72 years, respectively. Respective five year mortality after PVI for IC and CLTI was 37.2% and 71.1%; after IIB for IC and CLTI it was 37.8% and 60%; and after SIB for IC and CLTI it was 33.8% and 53.8%. On multivariable analysis, across all procedures, end stage renal disease, CLTI, congestive heart failure, anaemia, chronic obstructive pulmonary disease, and prior amputation were independently associated with increased mortality. Pre-admission home living and pre-operative aspirin use were independently associated with decreased mortality. CONCLUSION Long term survival in Medicare patients undergoing interventions in VQI centres for peripheral arterial disease is poor. Two thirds of CLTI patients and over one third of IC patients were not alive at five years. Intervening for IC in patients with high mortality risk should be avoided. For CLTI patients identified with decreased survival likelihood, intervention durability may be less important than invasiveness. Pre-operative medical optimisation should always be undertaken.

Abstract
Racial, ethnic, and gender disparities have received focused attention recently, as they became more visible in the COVID era. We continue to learn more about how healthcare disparities manifest for our patients and, more broadly, the structural underpinnings that result in predictable outcomes gaps. This review summarizes what we know about disparities relevant to interventional radiologists. The prevalence and magnitude of disparities are quantified and discussed where relevant. Specific examples are provided to demonstrate how factors like gender, ethnicity, social status, geography, etc. interact to create inequities in the delivery of interventional radiology (IR) care. Understanding and addressing health disparities in IR is crucial for improving real-world patient outcomes and reducing the economic burden associated with ineffective and low-value care. Finally, the importance of intentional mentorship, outreach, education, and equitable distribution of high-quality healthcare to mitigate these disparities and promote health equity in interventional radiology is discussed.

Abstract
Background Recent guidelines have emphasized the use of medical management, early diagnosis, and a multidisciplinary team to effectively treat patients with critical limb ischemia (CLI). Previous literature briefly highlighted the current racial disparities in its intervention. Herein, we analyze the trend over a 14-year time period to investigate whether the disparities gap in CLI management is closing. Methods and Results The National Inpatient Sample was queried between 2005 and 2018 for hospitalizations involving CLI. Nontraumatic amputations and revascularization were identified. Utilization trends of these procedures were compared between races (White, Black, Hispanic, Asian and Pacific Islander, Native American, and Other). Multivariable regression assessed differences in race regarding procedure usage. There were 6 904 562 admissions involving CLI in the 14-year study period. The rate of admissions in White patients who received any revascularization decreased by 0.23% (P<0.001) and decreased by 0.25% (P=0.025) for Asian and Pacific Islander patients. Among all patients, the annual rate of admission in White patients who received any amputation increased by 0.21% (P<0.001), increased by 0.19% (P=0.001) for Hispanic patients, and increased by 0.19% (P=0.012) for the Other race patients. Admissions involving Black, Hispanic, Asian and Pacific Islander, or Other race patients had higher odds of receiving any revascularization compared with White patients. All races had higher odds of receiving major amputation compared with White patients. Conclusions Our analysis highlights disparities in CLI treatment in our nationally representative sample. Non-White patients are more likely to receive invasive treatments, including major amputations and revascularization for CLI, compared with White patients.

Abstract
Chronic limb-threatening ischemia (CLTI) is associated with significant morbidity, including major limb amputation, and mortality. Healing ischemic wounds is necessary to optimise vascular outcomes and can be facilitated by dedicated appointments at a wound clinic. This study aimed to estimate the association between successful wound care initiation and 6-month wound healing, with specific attention to differences by race/ethnicity. This retrospective study included 398 patients with CLTI and at least one ischaemic wound who scheduled an appointment at our wound clinic between January 2015 and July 2020. The exposure was the completion status of patients' first scheduled wound care appointment (complete/not complete) and the primary outcome was 6-month wound healing (healed/not healed). The analysis focused on how this association was modified by race/ethnicity. We used Aalen-Johansen estimators to produce cumulative incidence curves and calculated risk ratios within strata of race/ethnicity. The final adjustment set included age, revascularization, and initial wound size. Patients had a mean age of 67 ± 14 years, were 41% female, 46% non-White and had 517 total wounds. In the overall cohort, 70% of patients completed their first visit and 34% of wounds healed within 6-months. There was no significant difference in 6-month healing based on first visit completion status for White/non-Hispanic individuals (RR [95% CI] = 1.18 [0.91, 1.45]; p-value = 0.130), while non-White individuals were roughly 3 times more likely to heal their wounds if they completed their first appointment (RR [95% CI] = 2.89 [2.66, 3.11]; p-value < 0.001). In conclusion, non-White patients were approximately three times more likely to heal their wound in 6 months if they completed their first scheduled wound care appointment while White/non-Hispanic individuals' risk of healing was similar regardless of first visit completion status. Future efforts should focus on providing additional resources to ensure minority groups with wounds have the support they need to access and successfully initiate wound care.

Abstract
Our study aimed to identify clinical outcomes and resource utilization associated with race and ethnicity in patients admitted with peripheral vascular disease (PVD) across the United States. We queried the National Inpatient Sample database from 2015 to 2019 and identified 622,820 patients admitted with PVD. Patients across 3 major race and ethnic categories were compared in terms of baseline characteristics, inpatient outcomes, and resource utilization. Black and Hispanic patients were more likely to be younger and of the lowest median income but incur higher total hospital costs. Black race predicted higher rates of acute kidney injury, need for blood transfusion, and need for vasopressor but lower rates of circulatory shock, and mortality. Black and Hispanic patients were less likely to undergo limb-salvaging procedures and more likely to undergo amputation than White patients. In conclusion, our findings indicate that Black and Hispanic patients experience health disparities in resource utilization and inpatient outcomes for PVD admissions.

Peripheral artery disease (PAD) affects approximately 230 million people worldwide and is associated with an increased risk of major adverse cardiovascular and limb events. Even though this condition is considered a cardiovascular equivalent, it remains an underrecognized and undertreated entity. Antiplatelet and statin therapy, along with smoking cessation, are the foundations of therapy to reduce adverse events but are challenging to fully implement in this patient population. Race and socioeconomic status also have profound impacts on PAD outcomes.

Abstract
The original description of the lower extremity bypass (LEB) provided surgeons with a reliable method of limb revascularization. The tenets of the operation have formed the foundation for the advances of surgical care. A careful evaluation of the chronic limb-threatening ischemia patient due to the numerous comorbid conditions is paramount to obtain the best possible outcomes. Use of all adjuncts including judicious target vessels control, completion imaging, and vein harvesting techniques to ensure optimal outcomes because a functioning LEB remains a key to successful limb salvage.

Abstract
Peripheral artery disease (PAD) affects 200 million individuals worldwide. In the United States, certain demographic groups experience a disproportionately higher prevalence and clinical effect of PAD. The social and clinical effect of PAD includes higher rates of individual disability, depression, minor and major limb amputation along with cardiovascular and cerebrovascular events. The reasons behind the inequitable burden of PAD and inequitable delivery of care are both multifactorial and complex in nature, including systemic and structural inequity that exists within our society. Herein, we present an overview statement of the myriad variables that contribute to PAD disparities and conclude with a summary of potential novel solutions.

[PMID: 39131653 PMCID: PMC11308495 DOI: 10.1016/j.jscai.2023.100982] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 04/03/2023] [Accepted: 04/10/2023] [Indexed: 08/13/2024]
Abstract
Background Chronic limb-threatening ischemia (CLTI) is a common condition with high rates of morbidity and mortality. Despite extensive literature documenting poor outcomes in patients with CLTI, as well as racial, ethnic, socioeconomic, and geographic disparities in these outcomes, process measures for high-quality CLTI care have not been developed. We developed the Chronic Limb threatening Ischemia Process PERformace (CLIPPER) cohort to develop and test the validity of CLTI care quality measures. Methods Using inpatient and outpatient claims data from patients with fee-for-service Medicare from 2010 to 2019, we created a coding algorithm to identify patients with CLTI. To qualify for a CLTI diagnosis, patients had to have either diagnostic codes for peripheral artery disease and for ulceration, infection, or gangrene on the same inpatient or outpatient claim or a CLTI-specific diagnostic code. Patients were also required to have a procedural code indicating arterial vascular testing within 6 months before or after the earliest qualifying CLTI diagnostic code(s). We describe baseline characteristics and long-term outcomes of this cohort. Results The final cohort comprised 1,130,065 patients diagnosed with CLTI between 2010 and 2019. Mean (±SD) age of the cohort was 75 ± 5.8 years; 48.4% were women, and 14.6% were Black. Within 30 days of CLTI diagnosis, 20.4% of patients underwent either percutaneous or surgical revascularization. Within 6 months, 3.3% of patients underwent major amputation; 16.7% of patients died within 1 year and 50.3% within 5 years. Conclusions We described the development of a cohort of fee-for-service Medicare patients with CLTI using inpatient and outpatient Medicare claims data. CLIPPER will be a resource for developing a set of process measures that can be captured from administrative claims data, with plans to describe their association with limb outcomes and corresponding racial, ethnic, socioeconomic, sex-based, and geographic variability.

Abstract
INTRODUCTION Disparity in access to emergency care among minority groups continues to exist despite growing awareness of the effect of implicit bias on public health. In this study, we evaluated ethnicity-based differences in time between admission and surgery for patients undergoing emergent procedures at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program. METHODS We conducted a retrospective review of 249,296 National Surgical Quality Improvement Program cases from 2006 to 2018 involving general, orthopaedic, and vascular surgeries. Analysis of variance was used to compare "time to operating room" (OR) between ethnic groups. RESULTS Notable differences in time to OR were noted among general and vascular surgeries but not orthopaedic surgery. Post hoc comparison identified notable variation in general surgery between White and Black/African Americans. In vascular surgery, notable variations were identified between White and Black/African Americans and White and Native Hawaiian/Pacific Islanders. DISCUSSION These findings suggest that certain surgical subspecialties continue to exhibit disparities in care that may manifest as surgical delay, most notably between White and Black/African Americans. Interestingly, variation in time to OR for patients treated by orthopaedic surgery was not notable. Overall, these results highlight the need for additional research into the role of implicit bias in emergent surgical care in the United States.

Association of Health Care Utilization and Access to Care With Vascular Assessment Before Major Lower Extremity Amputation Among US Veterans. JAMA Surg 2023; 158:e230479. [PMID: 37074700 PMCID: PMC10116382 DOI: 10.1001/jamasurg.2023.0479] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 12/10/2022] [Indexed: 04/20/2023]
Abstract
Importance Patient-level characteristics alone do not account for variation in care among US veterans with peripheral artery disease (PAD). Presently, the extent to which health care utilization and regional practice variation are associated with veterans receiving vascular assessment prior to major lower extremity amputation (LEA) is unknown. Objective To assess whether demographics, comorbidities, distance to primary care, the number of ambulatory clinic visits (primary and medical specialty care), and geographic region are associated with receipt of vascular assessment prior to LEA. Design, Setting, and Participants This national cohort study used US Department of Veterans Affairs' Corporate Data Warehouse data from March 1, 2010, to February 28, 2020, for veterans aged 18 or older who underwent major LEA and who received care at Veterans Affairs facilities. Exposures The number of ambulatory clinic visits (primary and medical specialty care) in the year prior to LEA, geographic region of residence, and distance to primary care. Main Outcomes and Measures The main outcome was receipt of a vascular assessment (vascular imaging study or revascularization procedure) in the year prior to LEA. Results Among 19 396 veterans, the mean (SD) age was 66.78 (10.20) years and 98.5% were male. In the year prior to LEA, 8.0% had no primary care visits and 30.1% did not have a vascular assessment. Compared with veterans with 4 to 11 primary care clinic visits, those with fewer visits were less likely to receive vascular assessment in the year prior to LEA (1-3 visits: adjusted odds ratio [aOR], 0.90; 95% CI, 0.82-0.99). Compared with veterans who lived less than 13 miles from the closest primary care facility, those who lived 13 miles or more from the facility were less likely to receive vascular assessment (aOR, 0.88; 95% CI, 0.80-0.95). Veterans who resided in the Midwest were most likely to undergo vascular assessment in the year prior to LEA than were those living in other regions. Conclusions and Relevance In this cohort study, health care utilization, distance to primary care, and geographic region were associated with intensity of PAD treatment before LEA, suggesting that some veterans may be at greater risk of suboptimal PAD care practices. Development of clinical programs, such as remote patient monitoring and management, may represent potential opportunities to improve limb preservation rates and the overall quality of vascular care for veterans.

Abstract
BACKGROUND We assess the rates of device use and outcomes by race among patients undergoing lower extremity peripheral arterial intervention using the American College of Cardiology National Cardiovascular Data Registry-Peripheral Vascular Intervention (PVI) registry. METHODS Patients who underwent PVI between April 2014 and March 2019 were included. Socioeconomic status was evaluated using the Distressed Community Index score for patients' zip codes. Multivariable logistic regression was used to assess factors associated with utilization of drug-eluting technologies, intravascular imaging, and atherectomy. Among patients with Centers for Medicare and Medicaid Services data, we compared 1-year mortality, rates of amputation, and repeat revascularizations. RESULTS Of 63 150 study cases, 55 719 (88.2%) were performed in White patients and 7431 (11.8%) in Black patients. Black patients were younger (67.9 versus 70.0 years), had higher rates of hypertension (94.4% versus 89.5%), diabetes (63.0% versus 46.2%), less likely to be able to walk 200 m (29.1% versus 24.8%), and higher Distressed Community Index scores (65.1 versus 50.6). Black patients were provided drug-eluting technologies at a higher rate (adjusted odds ratio, 1.14 [95% CI, 1.06-1.23]) with no difference in atherectomy (adjusted odds ratio, 0.98 [95% CI, 0.91-1.05]) or intravascular imaging (adjusted odds ratio, 1.03 [95% CI, 0.88-1.22]) use. Black patients experienced a lower rate of acute kidney injury (adjusted odds ratio, 0.79 [95% CI, 0.72-0.88]). In Centers for Medicare and Medicaid Services-linked analyses of 7429 cases (11.8%), Black patients were significantly less likely to have surgical (adjusted hazard ratio, 0.40 [95% CI, 0.17-0.96]) or repeat PVI revascularization (adjusted hazard ratio, 0.42 [95% CI, 0.30-0.59]) at 1 year compared with White patients. There was no difference in mortality (adjusted hazard ratio [0.8-1.4]) or major amputation (adjusted hazard ratio, 2.5 [95% CI, 0.8-7.6]) between Black and White patients. CONCLUSIONS Black patients presenting for PVI were younger, had higher prevalence of comorbidities and lower socioeconomic status. After adjustment, Black patients were less likely to have surgical or repeat PVI revascularization after the index PVI procedure.

Abstract
INTRODUCTION Peripheral artery disease (PAD) is a common progressive atherosclerotic disease associated with significant morbidity and mortality in the US; however, data regarding PAD-related mortality trends are limited. This study aims to characterize contemporary trends in mortality across sociodemographic and regional groups. METHODS The Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) was queried for data regarding PAD-related deaths from 2000 to 2019 in the overall sample and different demographic (age, sex, race/ethnicity) and regional (state, urban-rural) subgroups. Crude and age-adjusted mortality rates (CMR and AAMR, respectively) per 100,000 people were calculated. Associated annual percentage changes (APC) were computed using Joinpoint Regression Program Version 4.9.0.0 trend analysis software. RESULTS Between 2000 and 2019, a total of 1,959,050 PAD-related deaths occurred in the study population. Overall, AAMR decreased from 72.8 per 100,000 in 2000 to 32.35 per 100,000 in 2019 with initially decreasing APCs followed by no significant decline from 2016 to 2019. Most demographic and regional subgroups showed initial declines in AAMRs during the study period, with many groups exhibiting no change in mortality in recent years. However, men, non-Hispanic (NH) Black or African American individuals, people aged ⩾ 85 years, and rural counties were associated with the highest AAMRs of their respective subgroups. Notably, there was an increase in crude mortality rate among individuals 25-39 years of age from 2009 to 2019. CONCLUSION Despite initial improvement, PAD-related mortality has remained stagnant in recent years. Disparities have persisted across several demographic and regional groups, requiring further investigation.

Abstract
Purpose It is unclear whether disparities in the care provided before lower extremity amputation (LEA) is driven by differences in receipt of diagnostic work-up versus revascularization attempts. Methods We performed a national cohort study of Veterans who underwent LEA between March 2010 and February 2020 to assess receipt of vascular assessment with arterial imaging and/or revascularization in the year prior to LEA. Results Among 19,396 veterans (mean age 66.8 years; 26.6% Black), Black veterans had diagnostic procedures more often than White veterans (47.5% vs. 44.5%) and revascularization as often (25.8% vs. 24.5%). Conclusion We must identify patient and facility-level factors associated with LEA as disparities do not appear related to differences in attempted revascularization.

Abstract
INTRODUCTION Prior studies have found considerable disparities in prevalence and outcomes for patients with peripheral arterial disease (PAD). This study compared rates of diagnostic testing, treatment patterns, and outcomes after diagnosis of PAD among commercially insured Black and White patients in the United States. METHODS Optum's de-identified Clinformatics® Data Mart Database (1/2016-6/2021) were used to identify Black and White patients with PAD; first PAD diagnosis was deemed study index date. Baseline demographics, markers of disease severity, and healthcare costs were compared between cohorts. Patterns of medical management and rates of major adverse limb events (MALE; including acute or chronic limb ischemia, lower-limb amputation) and cardiovascular (CV) events (stroke, myocardial infarction) during the available follow-up period were described. Outcomes were compared between cohorts using multinomial logistic regression models, Kaplan-Meier survival analysis, and Cox proportional hazards models. RESULTS A total of 669,939 patients were identified, with 454,382 White patients and 96,162 Black patients. Black patients were younger on average (71.8 years vs. 74.2 years), but had higher comorbid burden, concomitant risk factors, and CV medication use at baseline. Prevalence of diagnostic testing, revascularization procedures, and medication use was numerically higher among Black patients. Black patients were also more likely than the White patients to receive medical therapy without a revascularization procedure [adjusted odds ratio with 95% confidence interval (CI) = 1.47 (1.44-1.49)]. However, Black patients with PAD had higher incidence of MALE and CV events than White patients [adjusted hazard ratio for composite event (95% CI) = 1.13, (1.11-1.15)]. Except myocardial infarction, the hazards of individual components of MALE and CV events were also significantly higher among Black patients with PAD. CONCLUSIONS Results of this real-world study suggest that Black patients with PAD have higher disease severity at the time of diagnosis and are at increased risk of experiencing adverse outcomes following diagnosis.

Abstract
Recently, the United States experienced its first resurgence of major amputations in more than 20 years. Compounding this rise is a longstanding history of disparities. Patients identifying as non-Hispanic Black are twice as likely to lose a limb as those identifying as non-Hispanic White. Those identifying as Latino face a 30% increase. Rural patients are also more likely to undergo major amputations, and the rural-urban disparity is widening. We used the National Institute on Minority Health and Health Disparities framework to better understand these disparities and identify common factors contributing to them. Common factors were abundant and included increased prevalence of diabetes, possible lower rates of foot self-care, transportation barriers to medical appointments, living in disadvantaged neighborhoods, and lack of insurance. Solutions within and outside the health care realm are needed. Health care-specific interventions that embed preventative and ambulatory care services within communities may be particularly high yield.

Abstract
Chronic limb-threatening ischemia represents the morbid end stage of severe peripheral artery disease, with significant impact on patient quality of life. Early diagnosis of arterial insufficiency and referral for vascular intervention are essential for successful limb salvage. Disparate outcomes have been reported among patients residing in rural areas due to decreased access to care. Remote telemedicine outreach programs represent an opportunity to improve access to care in these rural communities. Establishment of a telehealth program requires identification of communities most in need of specialty care. After locating an ideal site, collaboration with local providers is necessary to develop a program that meets the specific needs of providers and patients. Surgeon guidance in development of screening and management algorithms ensures that patients obtain care reliably and with adjustments as needed to suit the referring provider, the patient, and the specialist. Telehealth evaluations can limit the financial burden associated with travel, while ensuring access to higher levels of care than are available in the patients' immediate area. Multiple barriers to telehealth exist. These include limited reimbursement, local provider resistance to new referral patterns, lack of in-person interaction and evaluation, and the inability to do a physical examination. Improved reimbursement models have made telehealth feasible, although care must be taken to ensure that practice patterns complement existing resources and are designed in a way that omits the need for in-person evaluation until the time of specialist intervention. Telemedicine is an underused tool in the arsenal of vascular surgeons. Targeted telehealth programs aid in increasing patient access to expert-level care, thereby improving health disparities that exist in rural populations.

Abstract
PURPOSE Various studies, mainly from North America, report worse outcomes in ethnic minority populations submitted to revascularization for peripheral arterial disease (PAD). Limited nationwide data in relation to ethnicity are available from Europe. OBJECTIVE The objective of the study is to compare the outcomes of femoral angioplasty/stenting procedures among different ethnic groups in England during the 10-year period from 2006 to 2015. MATERIALS AND METHODS The "Hospital Episode Statistics" database has been searched using International Classification of Diseases, Tenth Revision (ICD-10) codes to identify all cases of femoral angioplasty or stenting from English NHS Hospitals between January 1, 2006, and December 31, 2015. Subsequent mortality, second open or endovascular infrainguinal procedures, and major amputations on the same side within 2 years after the first procedure have been recorded. Patients were broadly categorized according to ethnicity as whites, Asians, and blacks. Chi-square test was used to demonstrate significant differences among ethnic groups and odds ratios (ORs) were calculated using white ethnic group as reference. RESULTS A total number of 70 887 femoral endovascular procedures were recorded in patients from the 3 ethnic groups. Two-year mortality in whites, Asians, and blacks was 18.3%, 22.1%, and 19.5% (p<0.001); rates of second endovascular procedure were 12.1%, 13.1%, and 13.5% (p=0.24); rates of open infrainguinal procedure were 5.6%, 4.5%, and 8.0% (p<0.001); and rates of major amputation were 4.8%, 4.1%, and 7.0% (p<0.001), respectively. Mortality was higher in Asians (OR=1.26, 95% confidence interval [CI]=1.10-1.45, p<0.01) compared with whites. On the contrary, blacks underwent more open arterial operations (OR=1.48, 95% CI=1.19-1.83, p<0.01) and more amputations (OR=1.49, 95% CI=1.18-1.87, p<0.01). There were no significant differences in the rates of second endovascular procedures. CONCLUSION Two-year mortality after femoral angioplasty/stenting is higher in Asians, whereas risk of limb loss is higher in blacks compared with whites. Reasons of these ethnic differences in outcomes following femoral endovascular procedures for PAD merit further study.

Abstract
BACKGROUND The association between socioeconomic factors and peripheral arterial disease (PAD) has not been as well characterized as other cardiovascular conditions. We sought to define how annual income and education level are associated with PAD in a well-characterized diverse set of adults with chronic kidney disease (CKD). METHODS The Chronic Renal Insufficiency Cohort Study (CRIC) is a multi-center, prospective cohort study designed to examine risk factors for progression of CKD and cardiovascular disease. Demographic, income, and education-level data, as well as clinical data including ankle-brachial index (ABI) were collected at baseline. Annual income was categorized as < $25,000, $25,000-50,000, $50,000-100,000, or above $100,000; educational level was categorized as some high school, high school graduate, some college, or college graduate. Participants with missing income data or incompressible ABI (>1.4) were excluded from initial analysis. Logistic regression was used to estimate the association of income and/or education level with PAD, defined as an enrollment ABI of <0.90, history of PAD, or history of PAD intervention. RESULTS A total of 4122 were included, mean age of participants was 59.5 years, 56% were male, and 44% were Black. There were 763 CRIC participants with PAD at study enrollment (18.5%). In the final multivariable logistic regression model, Black race (OR = 1.3, 95% CI 1.1-1.6, p = 0.004) and level of annual household income remained independently associated with PAD at the time of enrollment (income <$25,000 OR = 1.9, 95% CI 1.3-2.8, p < 0.001; income $25,000-50,000 OR = 1.6, 95% CI 1.1-2.3, p = 0.011; income $50,000-100,000 OR = 1.2, 95% CI 0.9-1.8, p = 0.246), relative to a baseline annual income of >$100,000 (overall p-value <0.001). Decreasing level of educational attainment was not independently associated with increased PAD at enrollment, but lower level of educational attainment was associated with increased PAD when income data was not adjusted for (p = 0.001). Interestingly, Black race (OR = 0.7, 95% CI 0.6-0.8, p < 0.001), female gender (OR = 0.8, 95% CI 0.7-0.9, p = 0.007), and income <$25,000 (OR = 0.7, 95% CI 0.5-0.9, p = 0.008) were significantly associated with decreased statin use even after controlling for cardiovascular conditions. CONCLUSIONS In this prospectively followed CKD cohort, lower annual household income and Black race were significantly associated with increased PAD at study enrollment. In contrast, educational level was not associated with PAD when adjusted for patient income data. Black race, female gender, and low income were independently associated with decreased statin use, populations which could be targets of future public health programs.

Abstract
OBJECTIVE The demand for vascular surgeons in the United States stands to far exceed the current supply. International medical graduates (IMGs) are not only vital to meeting the country's growing health care needs, but also help to advance clinical research and medical education in the field of vascular surgery. Nearly 17% of practicing vascular surgeons in the United States are IMGs, yet little is known about their relative contributions to academic vascular surgery. Our study aims to compare the academic profiles and funding support for IMG vascular surgeons to that of their US medical graduate (USMG) counterparts. METHODS A cross-sectional study was performed on all IMG and USMG academic vascular surgeons practicing in US-based hospitals with vascular surgery residency and/or fellowship programs. In addition to the baseline surgeon characteristics, academic profiles and research output were also collected. Furthermore, the National Institutes of Health (NIH) research reporting tool and open payments database were queried for any funding/payments to surgeons in both groups. Matching for year of vascular surgery training program graduation was performed where appropriate. RESULTS A total of 908 academic vascular surgeons were included; 759 (83.6%) were USMGs and 149 (16.4%) were IMGs. The median year of graduation was comparable between the two groups, but USMGs had a significantly higher proportion of female surgeons (23.6% vs 10.7%; P = .0003). There were no significant differences in the academic profiles and leadership positions between the two groups. Although research productivity is similar between the two groups, IMG surgeons were more likely to have first or senior-authorship papers (47.1% vs 37.5%; P < .001). Additionally, faculty departments chaired/cheifed by a USMG were less likely to be staffed with IMG vascular surgeons (1.6 surgeons vs 3.1 surgeons; P < .0001). Following grant analysis, USMG surgeons received more NIH R01 grants (5.7% vs 1.3%; P = .026). R01-funded surgeons had significantly greater research output by number of publications (121.0 vs 47.5), citations (3872 vs 938), H-index (32.0 vs 17.5), and average journal impact factor (>10: 86.7% vs 33.3%) (all P < .001). CONCLUSIONS The efforts to further diversify vascular surgery are vital to better serving an increasingly diverse US population, amid growing disparities in health care. Although IMGs account for a minority of academic vascular surgeons, and contribute significantly to their published research, they had less NIH R01 funding, warranting further investigation.

Abstract
BACKGROUND After the Centers for Medicare and Medicaid Services modified reimbursement rates for outpatient peripheral vascular intervention in 2008 with the intent of improving access to care, providers began to increasingly perform peripheral vascular interventions in privately owned office-based clinics. Little is known about the characteristics of patients treated in this setting and their long-term outcomes as compared with those treated in hospital-based centers. METHODS In this retrospective cohort study, Medicare beneficiaries ≥66 years undergoing outpatient femoropopliteal peripheral vascular interventions in office-based clinics and hospital-based centers from 2015 to 2017 were identified. Sociodemographics, comorbidities, and institutional characteristics were compared across sites. Multivariable Cox proportional hazards models were used to estimate the adjusted associations between practice site location and outcomes. The primary outcome was the composite of major amputation or death analyzed through the end of follow-up. RESULTS Among 134 869 patients, 29.9% were treated in office-based clinics and 70.1% in hospital-based centers. Patients treated in office-based clinics were more often Black (16.9% versus 11.9%), dually enrolled in Medicaid (26.3% versus 19.6%), and residents of lower-resourced regions (32.6% versus 25.6%). Over a median follow-up time of 800 days (interquartile range, 531-1119 days), patients treated in office-based clinics had reduced risks of major amputation or death compared with outpatients treated in hospital-based centers (hazard ratio, 0.92 [95% CI, 0.89-0.95]). They also had lower adjusted all-cause mortality (hazard ratio, 0.93 [95% CI, 0.90-0.96]), major lower extremity amputation (hazard ratio, 0.84 [95% CI, 0.79-0.89]), and all-cause hospitalization (hazard ratio, 0.86 [95% CI, 0.84-0.88]). These findings persisted after stratification by critical limb ischemia, race, dual enrollment, and regional socioeconomic status, as well as among operators treating patients in both clinical settings. CONCLUSIONS In this large nationwide analysis of Medicare beneficiaries, office-based clinics treated a more socioeconomically disadvantaged population compared with hospital-based centers. Long-term outcomes were comparable between locations. As such, these clinics appear to be selecting lower-risk patients for outpatient peripheral vascular interventions, although there remains the possibility of unmeasured confounding.

Abstract
Racial, ethnic, and sex-based healthcare disparities have been documented for the past several decades. Nonetheless, disparities remain firmly entrenched in our care delivery systems, with multiple contributing factors, including patient interactions with care providers, systemic barriers to access, and socioeconomic determinants of health. Interventional radiology is also subject to these drivers of health inequity. In this review, documented disparities for the most common conditions being addressed by interventional radiologists are summarized; their magnitude is quantified where relevant, and underlying drivers are identified. Specific examples are provided to illustrate how medical, cultural, and socioeconomic factors interact to produce unequal outcomes. By outlining known disparities and common contributors, this review aims to motivate future efforts to mitigate them.

Abstract
Background Peripheral artery disease (PAD) increases the risk of cardiovascular events and limb events including amputations. PAD is twice as prevalent in Black compared with non-Hispanic White individuals, especially among men. Screening for PAD using the ankle-brachial index in community settings, such as the barbershop, could lead to earlier diagnosis and treatment. Methods and Results A pilot study was conducted at 2 barbershops in Cleveland, OH from June to December 2020 to assess the feasibility of screening for PAD in the barbershop setting and the effect of an educational intervention on PAD awareness. After screening with both automated and Doppler ankle-brachial index, PAD was identified in 5/31 (16.1%) of participants. Baseline systolic blood pressure, low-density lipoprotein cholesterol, and random blood glucose were higher in participants who screened positive for PAD (P<0.001). PAD awareness was low overall. There was a significant improvement in PAD awareness assessment scores obtained at the initial and exit visits (9.93±4.23 to 12.50±4.41, P=0.004). An association was found between PAD awareness at baseline and highest education level achieved: compared with those with some college/associate's degree or higher, non-high school graduates scored lower on PAD awareness (P=0.022), as did those who only had a high school diploma or tests of General Educational Development (P=0.049). Conclusions In a pilot study, barbershop-based screening for PAD among Black men revealed a higher than expected PAD prevalence and low PAD awareness. An educational video was effective at increasing PAD awareness. Ankle-brachial index screening and educational outreach in the barbershop may be a feasible and effective tool to diagnose PAD and reduce PAD disparities among Black men at highest risk.

Abstract
OBJECTIVE To examine variations in timing of lower-limb amputation (LLA) across race/ethnicity and sex among older adults with a diabetic foot ulcer (DFU). It was hypothesized Black/African Americans were more likely to have LLA post-DFU earlier compared with non-Hispanic/Whites, and more men would receive LLA earlier post-DFU compared with women. RESEARCH DESIGN AND METHODS This was a retrospective cohort analysis of enrolled Medicare fee-for-service (FFS) beneficiaries with a diagnosis of DFU during the study period (2012-2017), allowing up to 5 years post-DFU. Final analytic sample contained 643,287 individuals; the subsample consisted of 68,633 individuals with LLA only. The primary outcome was mutually exclusive groups based on timing of LLA. Multinomial logistic regression was applied to assess likelihood of membership into a group post-DFU based on characteristics such as sex and race/ethnicity. RESULTS Black/African American beneficiaries had 1.98 (95% CI 1.93-2.03) times the odds of receiving an LLA within 1 year of DFU diagnosis compared with non-Hispanic/White beneficiaries relative to no amputation. Female beneficiaries had increased odds (odds ratio [OR] 1.07, 95% CI 1.02-1.11] between 1 and 3 years and OR 1.08 [95% CI 1.03-1.12] in ≥3 years) of a delayed LLA compared with men among those that underwent LLA. CONCLUSIONS Notably, these results present novel evidence on timing of LLA between racial groups and sex for Medicare FFS beneficiaries post-DFU. Results may be generalizable to individuals with Medicare FFS and DFU. Clinically more targeted, evidence-based decision making informs care decisions with opportunities to address inequities related to the social determinants of health that may lead to LLA.

A systematic review of racial/ethnic disparities in pharmacotherapy and surgical treatment outcomes in peripheral arterial disease among African American/non-Hispanic Black, non-Hispanic White and Hispanic patients. AMERICAN HEART JOURNAL PLUS : CARDIOLOGY RESEARCH AND PRACTICE 2022; 18:100179. [PMID: 38559417 PMCID: PMC10978335 DOI: 10.1016/j.ahjo.2022.100179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 07/05/2022] [Accepted: 07/07/2022] [Indexed: 04/04/2024]
Abstract
Background Lower extremity peripheral arterial disease (PAD) is associated with significant morbidity and mortality in racial/ethnic diverse populations. However, limited data exist on treatment outcome disparities in racial/ethnic diverse populations, particularly in AA/NHB populations. Objective The aim of this systematic review is to analyze disparities in the outcomes of PAD treatments, particularly pharmacotherapy and surgery, among racial/ethnic groups in the US. Methods A comprehensive search of original investigations pertaining to PAD treatments between 2015 and 2021 was performed. Quality assessment of the studies was also completed. Results Fourteen studies were included. Thirteen studies reported differences in treatment outcomes for surgical intervention, and one study reported differences for concurrent surgical and pharmacotherapy. NHB and Hispanic/Latinx ethnicities were associated with decreased overall and perioperative mortality in four studies. Six studies noted increased amputation risk among racial/ethnic diverse populations. Only one study noted significant survival benefit by race/ethnicity. Three studies noted increased risk of major adverse limb events and post-operative complications. One study noted increased limb patency after intervention in racial/ethnic cohorts. Overall, all studies reported high methodological quality with adequate assessment of outcomes and follow-up of cohort. Conclusion In this analysis, the predominant intervention reported is surgical. Overall, racial/ethnic populations are less likely to experience PAD-associated mortality but are more likely to experience adverse events. Further studies are necessary to include all racial/ethnic diverse populations in assessing PAD therapeutic intervention outcomes. Moreover, targeted public health efforts are necessary to increase PAD educational awareness, community-driven risk modification, and patient-centered care planning.

Abstract
Peripheral artery disease (PAD), the pathophysiologic narrowing of arterial blood vessels of the lower leg due to atherosclerosis, is a highly prevalent disease that affects more than 6 million individuals 40 years and older in the United States, with sharp increases in prevalence with age. Morbidity and mortality rates in patients with PAD range from 30% to 70% during the 5- to 15-year period after diagnosis and PAD is associated with poor health outcomes and reduced functionality and quality of life. Despite advances in medical, endovascular, and open surgical techniques, there is striking variation in care among population subgroups defined by sex, race and ethnicity, and socioeconomic status, with concomitant differences in preoperative medication optimization, amputation risk, and overall health outcomes. We reviewed studies from 1995 to 2021 to provide a comprehensive analysis of the current impact of disparities on the treatment and management of PAD and offer action items that require strategic partnership with primary care providers, researchers, patients, and their communities. With new technologies and collaborative approaches, optimal management across all population subgroups is possible.

Closing the Gaps in Racial Disparities in Critical Limb Ischemia Outcome and Amputation Rates: Proceedings from a Society of Interventional Radiology Foundation Research Consensus Panel. J Vasc Interv Radiol 2022; 33:593-602. [PMID: 35489789 DOI: 10.1016/j.jvir.2022.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 01/15/2022] [Accepted: 02/10/2022] [Indexed: 11/29/2022] Open
Abstract
Minority patients such as Blacks, Hispanics, and Native Americans are disproportionately impacted by critical limb ischemia and amputation due to multiple factors such as socioeconomic status, type or lack of insurance, lack of access to health care, capacity and expertise of local hospitals, prevalence of diabetes, and unconscious bias. The Society of Interventional Radiology Foundation recognizes that it is imperative to close the disparity gaps and funded a Research Consensus Panel to prioritize a research agenda. The following research priorities were ultimately prioritized: (a) randomized controlled trial with peripheral arterial disease screening of at-risk patients with oversampling of high-risk racial groups, (b) prospective trial with the introduction of an intervention to alter a social determinant of health, and (c) a prospective trial with the implementation of an algorithm that requires criteria be met prior to an amputation. This article presents the proceedings and recommendations from the panel.

The Association Between Socioeconomic Factors and Incident Peripheral Artery Disease in the Chronic Renal Insufficiency Cohort (CRIC). Ann Vasc Surg 2022; 80:196-205. [PMID: 34656710 PMCID: PMC8977117 DOI: 10.1016/j.avsg.2021.07.057] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 07/26/2021] [Accepted: 07/27/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND The association between socioeconomic factors and development of peripheral artery disease (PAD) has not been as well characterized compared to other cardiovascular diseases. We sought to define how annual income, sex, race, and education level are associated with newly diagnosed PAD in a well-characterized, diverse set of adults with CKD. METHODS The Chronic Renal Insufficiency Cohort Study (CRIC) is a multicenter, prospective cohort study designed to examine risk factors for progression of CKD and cardiovascular disease. Demographic and clinical data including ankle brachial index (ABI) and interventions were collected at baseline, as well as yearly during follow-up visits. Annual income was categorized as: <$25,000, $25,000-50,000, $50,000-100,000, or above $100,000. We excluded those with pre-existing PAD, defined as enrollment ABI of <0.9 or >1.4, or missing income data. Cox proportional hazards regression was used to estimate the risk for incident PAD during CRIC enrollment, defined as a drop in ABI to <0.90 or a confirmed PAD intervention, including revascularization or amputation. RESULTS A total of 3,313 patients met inclusion criteria, the mean age was 58.7 years, 56% were male, and 42% were Black. Over a median follow-up of 10.1 years, 639 participants (19%) were newly diagnosed with PAD. After adjusting for cardiovascular risk factors, all lower levels of annual household income were associated with increased incidence of PAD (income <$25,000 HR 1.7, 95% CI 1.1-2.4, P = 0.008; income $25,000-50,000 HR 1.5, 95% CI 1.1-2.3, P = 0.009; income $50,000-100,000 HR 1.6, 95% CI 1.2-2.4, P = 0.004), relative to a baseline annual income of >$100,000 (overall P-value = 0.02). In the multivariable model, there was no association between education level and PAD incidence (P = 0.80). Black race (HR 1.2, 95% CI 1.0-1.5, P = 0.023) and female sex (HR 1.7, 95% CI 1.4-2.0, P < 0.001) were independently associated with PAD incidence. Multiple imputation analysis provided similar results. CONCLUSIONS In the CRIC, a multi-center cohort of prospectively followed CKD patients undergoing yearly CVD surveillance, lower annual household income, female sex, and Black race were significantly associated with the PAD incidence. In contrast, level of education was not independently associated with incident PAD.

Contemporary Outcomes of Limb-Salvage Procedures Using Vascular Quality Initiative-Medicare Linked Data: Racial and Ethnic Disparities Persist. J Vasc Surg 2022; 75:2013-2018.

Abstract
INTRODUCTION Several reports have shown that ethnic and racial minorities with chronic limb-threatening ischemia (CLTI) are more likely to undergo major amputation. Whether this disparity is driven by limited access to care, statistical discrimination or biological factors remains a matter of debate. We sought to study the effect of race/ethnicity on short and long-term outcomes of limb-salvage procedures among patients with new onset CLTI. METHODS We identified all patients who underwent first time (open or endovascular) revascularization for CLTI between January 2010 and December 2016 in the Vascular Quality Initiative-Medicare linked database. These patients were divided into non-Hispanic whites (NHW) and racial/ethnic minority (REM) groups. Early end points included length of stay and operative mortality, while 2-year outcomes included major amputation, freedom from subsequent revascularization, number of limb salvage reinterventions and all-cause mortality. A sub-analysis comparing NHWs to Hispanics and NHWs to blacks was also performed. RESULTS Of 16,249 presenting with CLTI, 73.9% were non-Hispanic whites. Racial/ethnic minority patients were younger (mean age, 69.9 ± 11.3 years vs 74.2 ± 10.5 years; P < .001) and more likely to be female (45.9% vs 37.7%; P < .001). Other baseline differences included a higher rate of smoking history, coronary artery disease, chronic obstructive pulmonary disease and chronic kidney disease among non-Hispanic whites, whereas racial/ethnic minority patients were more likely to have diabetes and hypertension and more likely to present with tissue loss (78% vs 76.6%; P =.04). Preoperative ankle-brachial index and procedure type (endovascular vs open) were similar between the groups. On multivariable analysis, NHW's had a 13% increase in length of stay and a 25% decrease in operative mortality. In regard to 2-year outcomes, limb salvage estimates were 86% for the NHW group versus 77.1% for the REM group; P < .001. Comparison between the two groups showed similar rates of freedom from subsequent revascularization (67.9% vs 67.1%; P =.2). REM patients achieved higher rates of overall survival (70.3% vs 68.4%; P =.01) when compared to their white counterparts. Patients in the REM group were more likely to undergo more than two limb salvage reinterventions during follow-up (14.2% vs 8.6%; P < .001). After adjusting for potential confounders, REM patients had significantly higher odds of major amputation at 2 years (adjusted hazard ratio, 1.49; 95% confidence interval, 1.36-1.63; P < .001) CONCLUSIONS: In this Vascular Quality Initiative-Medicare matched study, racial and ethnic minority patients continue to face a higher major amputation risk despite having equivalent attempts at limb salvage. Further studies identifying risk factors and evaluating intervention strategies that may be more effective in preventing amputation in this particular population are warranted.

Abstract
Background Racial and ethnic disparities in outcomes following lower limb revascularization for peripheral artery disease have been ascribed to disease severity at presentation for surgery. Methods and Results We calculated 1-year risk of major adverse limb events (MALEs), major amputation, and death for patients undergoing elective revascularization for claudication or chronic limb-threatening ischemia in the Vascular Quality Initiative data (2011-2018). We report hazard ratios according to race and ethnicity using Cox (death) or Fine and Gray subdistribution hazards models (MALE and major amputation, treating death as a competing event), adjusted for patient, treatment, and anatomic factors associated with disease severity. Among 88 599 patients (age, 69 years; 37% women), 1-year risk of MALE (major amputation and death) was 12.8% (95% CI, 12.5-13.0) in 67 651 White patients, 16.5% (95% CI, 5.8-7.8) in 15 442 Black patients, and 17.2% (95% CI, 5.6-6.9) in 5506 Hispanic patients. Compared with White patients, we observed an increased hazard of poor limb outcomes among Black (MALE: 1.17; 95% CI, 1.12-1.22; amputation: 1.52; 95% CI, 1.39-1.65) and Hispanic (MALE: 1.22; 95% CI, 1.14-1.31; amputation: 1.45; 95% CI, 1.28-1.64) patients. However, Black and Hispanic patients had a hazard of death of 0.85 (95% CI, 0.79-0.91) and 0.71 (95% CI, 0.63-0.79) times the hazard among White patients, respectively. Worse limb outcomes were observed among Black and Hispanic patients across subcohorts of claudication and chronic limb-threatening ischemia. Conclusions Black and Hispanic patients undergoing infrainguinal revascularization for chronic limb-threatening ischemia and claudication had worse limb outcomes compared with White patients, even with similar disease severity at presentation. Additional investigation aimed at eliminating disparate limb outcomes is needed.

Abstract
Background Socioeconomic factors have been shown to be associated with amputation in peripheral artery disease (PAD); however, analyses have normally focused on insurance status, race, or median income. We sought to determine whether community-level socioeconomic distress was associated with major amputation and if that association differed by race. Materials and methods Community-level socioeconomic distress was measured using the distressed communities index (DCI). The DCI is a zip code level compositive socioeconomic score (0-100) that accounts for unemployment, education level, poverty rate, median income, business growth, and housing vacancies. A distressed community was defined as a zip code with DCI of 40 or greater. We calculated one-year risk of major amputation by DCI score for individuals with peripheral artery disease in South Carolina, 2012-2017. Treating death as competing event, we reported Fine and Gray subdistribution hazards ratios (sdHR), adjusted for patient demographic and clinical comorbidities associated with amputation. Further analyses were completed to identify potential differences in outcomes within strata of race and DCI. Results Among 82,848 individuals with peripheral artery disease, the one-year incidence of amputation was 3.5% (95% CI: 3.3%, 3.6%) and was significantly greater in distressed communities than non-distressed communities (3.9%; 95% CI: 3.8%, 4.1% vs. 2.4%; 95% CI: 2.2%, 2.6%). After controlling for death and adjusting for covariates, we found an increased hazard of amputation among individuals in a distressed community (sdHR: 1.25; 95% CI: 1.14, 1.37), which persisted across racial strata. However, regardless of DCI score, Black individuals had the highest incidence of amputation. Conclusion Socioeconomic status is independently predictive of limb amputation after controlling for demographic characteristics and clinical comorbidities. Race continues to be an important risk factor, with Black individuals having higher incidence of amputation, even in non-distressed communities, than White individuals had in distressed communities.

Abstract
INTRODUCTION This study assessed the association between race/ethnicity and amputation with mortality and loss of independence (LOI) for diabetic gangrene. METHODS We analyzed the American College of Surgeons National Surgery Quality Improvement Program database from 2016 to 2019. Chi-squared tests were performed to evaluate differences in baseline characteristics and complications. Multivariable logistic regression was performed to model LOI and 30-day mortality. RESULTS 5250 patients with diabetes underwent lower extremity amputation as treatment for gangrene. Hispanic patients were more likely to undergo below the knee amputation (BKA) (P = 0.006). Guillotine amputation (GA) was associated with age > 65 (P < 0.0001), independent functional status prior to admission (P < 0.0001), and mortality (OR 1.989, 95%CI 1.29-3.065), but was not associated with LOI. Mortality was less frequent in Black patients (OR 0.432, 95%CI 0.207-0.902), but loss of independence (LOI) was more frequent in Black patients (OR 1.373, 95%CI 1.017-1.853). Hispanic patients were less likely to experience LOI (OR 0.575, 95%CI 0.477-0.693). CONCLUSIONS LOI and mortality provide contrasting perspectives on outcomes following lower extremity amputation. Further assessment of risk factors may illuminate healthcare disparities.

Abstract
BACKGROUND Previous studies have documented that Black patients have worse outcomes after lower extremity revascularization procedures compared with White patients. However, the association of race on carotid endarterectomy (CEA) outcomes is not well described. The aim of this study was to compare perioperative outcomes of CEA for Black vs White patients with asymptomatic carotid artery stenosis. STUDY DESIGN All patients who underwent CEA for asymptomatic carotid stenosis in the ACS-NSQIP targeted vascular database (2011-2019) were included. Perioperative (30-day) outcomes were compared for Black vs White patients using multivariable logistic regression adjusting for age/sex, comorbidities, and disease characteristics. RESULTS Of 16,764 asymptomatic CEA patients, 95.2% (N = 15,960) were White and 4.8% (N = 804) were Black. Black patients were slightly younger (mean age 71.4 ± 0.1 vs 69.9 ± 0.3 years, P < 0.001) and more frequently had high-grade carotid artery stenosis compared to White patients (79.5% vs 74.0%, p = 0.001). Comorbidities including hypertension, diabetes, kidney disease, congestive heart failure, and coronary artery disease were all more prevalent among Black patients (p ≤ 0.01). Crude perioperative stroke (2.4% vs 1.3%, p = 0.007) and stroke/death (2.6% vs 1.4%, p = 0.003) were higher for Black patients, but myocardial infarction (1.7% vs 1.5%, p = 0.67) and death (0.4% vs 0.2%, p = 0.12) were similar. After adjusting for baseline differences between groups, the risk of perioperative stroke (odds ratio 1.66, 95% CI 1.01 to 2.73) and stroke/death (odds ratio 1.75, 95% CI 1.10 to 2.81) remained significantly higher for Black patients compared with White patients. CONCLUSIONS Black patients undergoing CEA for asymptomatic carotid artery stenosis had more severe stenosis, more comorbidities, and worse perioperative outcomes compared to White patients. Overall, our data suggest substantial differences in the treatment and outcomes of asymptomatic carotid artery stenosis based on race.
