Racial disparities in prosthesis abandonment and mobility outcomes after lower limb amputation from a dysvascular etiology in a veteran population. PM R 2024. [PMID: 39099545 DOI: 10.1002/pmrj.13240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 03/29/2024] [Accepted: 05/16/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND Non-Hispanic Black (NHB) individuals have higher rates of amputation and increased risk of a transfemoral amputation due to dysvascular disease than non-Hispanic White (NHW) individuals. However, it is unclear if NHB individuals have differences in prosthesis use or functional outcomes following an amputation. OBJECTIVE To determine if there are racial disparities in prosthesis abandonment and mobility outcomes in veterans who have undergone their first major unilateral lower extremity amputation (LEA) due to diabetes and/or peripheral artery disease. DESIGN National cohort study that identified individuals retrospectively through the Veterans Affairs (VA) Corporate Data Warehouse (CDW) from March 1, 2018, to November 30, 2020, then prospectively collected their self-reported prosthesis abandonment and mobility. Multiple logistic regression was used to control for potential confounders and identify potential effect modifiers. SETTING The VA CDW, participant mailings and phone calls. PARTICIPANTS Three hundred fifty-seven individuals who underwent an incident transtibial or transfemoral amputation due to diabetes and/or peripheral arterial disease. INTERVENTIONS Not applicable. MAIN OUTCOMES MEASURES (1) Self-reported prosthesis abandonment. (2) Level of mobility assessed using the Locomotor Capabilities Index. RESULTS Rurally located NHB individuals without a major depressive disorder (MDD) had increased odds of abandoning their prosthesis (adjusted odds ratios [aOR] = 5.3; 95% confidence interval [CI]: [1.3-21.1]). This disparity was nearly three times as large for rurally located NHB individuals with MDD diagnosis, compared with other races from rural areas and with MDD (aOR = 15.8; 95% CI, 2.5-97.6). NHB individuals living in an urban area were significantly less likely to achieve advanced mobility, both with MDD (aOR=0.16; 95% CI: [0.04-7.0]) and without MDD (aOR = 0.26; 95% CI: [0.09-0.73]). CONCLUSIONS This study demonstrated that health care disparities persist for NHB veterans following a dysvascular LEA, with increased prosthesis abandonment and worse mobility outcomes.

A systematic review and meta-analysis on the influence of sociodemographic factors on amputation in patients with peripheral arterial disease. J Vasc Surg 2024; 79:169-178.e1. [PMID: 37722513 DOI: 10.1016/j.jvs.2023.08.130] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 08/07/2023] [Accepted: 08/16/2023] [Indexed: 09/20/2023]
Abstract
OBJECTIVE To identify disparities in sociodemographic factors that are associated with major lower limb amputation in patients with peripheral arterial disease (PAD). METHODS A systematic review of the literature was performed to identify studies that reported major lower limb amputation rates in patients with PAD among different sociodemographic groups. Data that compared amputation rates on the basis of sex, race, ethnicity, income, insurance, geography, and hospital type were collected and described. Outcomes were then aggregated and standardized, and a meta-analysis was performed to synthesis data into single odds ratios (ORs). RESULTS Forty-one studies were included in the review. There was no association found between males and females (OR, 0.95; 95% confidence interval [CI], 0.90-1.00). Compared with Whites, higher rates of amputation were seen among Blacks/African Americans (OR, 2.02; 95% CI, 1.81-2.26) and Native Americans (OR, 1.22; 95% CI, 1.04-1.45). No significant association was found between Whites and Asians, Native Hawaiians, or Pacific Islanders (OR, 1.15; 95% CI, 1.00-1.33). Hispanics had higher rates of amputation compared with non-Hispanics (OR, 1.36; 95% CI, 1.22-1.52). Compared with private insurance, higher rates of amputation were seen among Medicare patients (OR, 1.38; 95% CI, 1.27-1.50), Medicaid patients (OR, 1.59; 95% CI, 1.44-1.76), and noninsured patients (OR, 1.41; 95% CI, 1.02-1.95). Compared with the richest income quartile, higher rates of amputation were seen among the second income quartile (OR, 1.10; 95% CI, 1.05-1.15), third income quartile (OR, 1.20; 95% CI, 1.07-1.35), and bottom income quartile (OR, 1.36; 95% CI, 1.24-1.49). There was no association found between rural and urban populations (OR, 1.35; 95% CI, 0.92-1.97) or between teaching and nonteaching hospitals (OR, 1.01; 95% CI, 0.91-1.12). CONCLUSIONS Our study has identified a number of disparities and quantified the influence of sociodemographic factors on major lower limb amputation rates owing to PAD between groups. We believe these findings can be used to better target interventions aimed at decreasing amputation rates, although further research is needed to better understand the mechanisms behind our findings.

Abstract
Low-cost techniques that can detect the presence of vascular calcification (VC) in chronic kidney disease (CKD) patients could improve clinical outcomes. In this study, we established a near-infrared spectroscopy-based imaging technique to determine changes in peripheral hemodynamics due to CKD-induced VC. Mice were fed a high-adenine diet with either normal or high levels of phosphate to induce CKD with and without VC, respectively. The mice tail was imaged to evaluate hemodynamic changes in response to occlusion. The rate of change in oxyhemoglobin in response to occlusion showed a statistically significant difference in the presence of VC in the mice.

Abstract
BACKGROUND Lower-limb amputation rates in patients with chronic limb-threatening ischemia vary across the United States, with marked disparities in amputation rates by gender, race, and income status. We evaluated the association of patient, hospital, and geographic characteristics with the intensity of vascular care received the year before a major lower-limb amputation and how intensity of care associates with outcomes after amputation. METHODS Using Medicare claims data (2016-2019), beneficiaries diagnosed with chronic limb-threatening ischemia who underwent a major lower-limb amputation were identified. We examined patient, hospital, and geographic characteristics associated with the intensity of vascular care received the year before amputation. Secondary objectives evaluated all-cause mortality and adverse events following amputation. RESULTS Of 33 036 total Medicare beneficiaries undergoing major amputation, 7885 (23.9%) were due to chronic limb-threatening ischemia; of these, 4988 (63.3%) received low-intensity and 2897 (36.7%) received high-intensity vascular care. Mean age, 76.6 years; women, 38.9%; Black adults, 24.5%; and of low income, 35.2%. After multivariable adjustment, those of low income (odds ratio, 0.65 [95% CI, 0.58-0.72]; P<0.001), and to a lesser extent, men (odds ratio, 0.89 [95% CI, 0.81-0.98]; P=0.019), and those who received care at a safety-net hospital (odds ratio, 0.87 [95% CI, 0.78-0.97]; P=0.012) were most likely to receive low intensity of care before amputation. High-intensity care was associated with a lower risk of all-cause mortality 2 years following amputation (hazard ratio, 0.79 [95% CI, 0.74-0.85]; P<0.001). CONCLUSIONS Patients who were of low-income status, and to a lesser extent, men, or those cared for at safety-net hospitals were most likely to receive low-intensity vascular care. Low-intensity care was associated with worse long-term event-free survival. These data emphasize the continued disparities that exist in contemporary vascular practice.

Abstract
Peripheral artery disease (PAD) is caused by blocked arteries due to atherosclerosis and/or thrombosis which reduce blood flow to the lower limbs. It results in major morbidity, including ischemic limb, claudication, and amputation, with patients also suffering a heightened risk of heart attack, stroke, and death. Recent studies suggest women have a higher prevalence of PAD than men, and with worse outcomes after intervention. In addition to a potential unconscious bias faced by women with PAD in the health system, with underdiagnosis, and lower rates of guideline-based therapy, fundamental biological differences between men and women may be important. In this review, we highlight sexual dimorphisms in endothelial cell functions and how they may impact PAD pathophysiology in women. Understanding sex-specific mechanisms in PAD is essential for the development of new therapies and personalized care for patients with PAD.

Abstract
INTRODUCTION This study investigated disparities in health care access for Hispanic adults with diabetes and peripheral artery disease (PAD) who are at risk of lower-extremity amputation and other cardiovascular morbidities and mortalities. METHODS We utilized the health care access survey data from the All of Us research program to examine adults (⩾ 18 years) with either diabetes and/or PAD. The primary associations evaluated were: could not afford medical care and delayed getting medical care in the past 12 months. Multivariable logistic regression models were used to assess the association of Hispanic ethnicity and survey responses, adjusting for age, sex, income, health insurance, and employment status. RESULTS Among 24,104 participants, the mean age was 54.9 years and 67% were women. Of these, 8.2% were Hispanic adults. In multivariable analysis, Hispanic adults were more likely to be unable to afford seeing a health care provider, and receiving emergency care, follow-up care, and prescription medications (p < 0.05) than non-Hispanic adults. Furthermore, Hispanic adults were more likely to report being unable to afford medical care due to cost (odds ratios [OR] 1.72, 95% CI 1.50-1.99), more likely to purchase prescription drugs from another country (OR 2.20, 95% CI 1.69-2.86), and more likely to delay getting medical care due to work (OR 1.46, 95% CI 1.22-1.74) and child care (OR 1.80, 95% CI 1.35-2.39) issues than non-Hispanic White adults. CONCLUSION The Hispanic population with diabetes and PAD faces substantial barriers in health care access, including a higher likelihood of delaying medical care and being unable to afford it.

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
BACKGROUND AND AIMS Lower extremity bypass surgery is an effective treatment option for patients with chronic limb-threatening ischemia (CLTI). Recent studies have suggested that sex-based differences may impact patient outcomes following lower extremity revascularization, however, results have been inconsistent. METHODS In this multicenter analysis, we retrospectively identified all infrainguinal bypass procedures performed for CLTI from 2002 to 2021. Patients were separated into two groups based on sex. Primary outcomes were major limb amputation and reintervention for graft patency. RESULTS Of 843 bypasses performed over the study period, 347 (41.2%) patients were female. Racial/ethnic distribution and medical comorbidities were similar across sex groups. Surgical indications and operative details were also similar between groups, including conduit type (49.9% autogenous), bypass target (65.4% infrageniculate), and concurrent endarterectomy (38.9%). Female and male patients had similar hospital length of stay (6 days [4-9] vs 6 days [4-9]), hospital readmission (25.6% vs 25.0%), and postoperative complications (p=NS each). Female patients had higher major amputation rates (10.1% vs 6.3%, p=0.04) after one year, whereas reintervention rates were similar between groups (26.2% vs 24.6%, p=NS). After accounting for patient factors, female sex (odds ratio [OR] 1.02 [1.00-1.04]), infrageniculate target (OR 1.02 [1.00-1.04]), and bypass for tissue loss (OR 1.02 [1.00-1.04]) were associated with major amputation after bypass (p<0.05 each). CONCLUSIONS Female sex is associated with a small but significant increase major amputation after lower extremity bypass surgery for CLTI, despite similar clinical presentation, medical comorbidities, and operative details. These data support the increasingly recognized sex disparities in peripheral arterial disease.

Abstract
Cardiovascular disease is the leading cause of death in women and men globally, with most due to atherosclerotic cardiovascular disease (ASCVD). Despite progress during the last 30 years, ASCVD mortality is now increasing, with the fastest relative increase in middle-aged women. Missed or delayed diagnosis and undertreatment do not fully explain this burden of disease. Sex-specific factors, such as hypertensive disorders of pregnancy, premature menopause (especially primary ovarian insufficiency), and polycystic ovary syndrome are also relevant, with good evidence that these are associated with greater cardiovascular risk. This position statement from the European Atherosclerosis Society focuses on these factors, as well as sex-specific effects on lipids, including lipoprotein(a), over the life course in women which impact ASCVD risk. Women are also disproportionately impacted (in relative terms) by diabetes, chronic kidney disease, and auto-immune inflammatory disease. All these effects are compounded by sociocultural components related to gender. This panel stresses the need to identify and treat modifiable cardiovascular risk factors earlier in women, especially for those at risk due to sex-specific conditions, to reduce the unacceptably high burden of ASCVD in women.

Black or African American patients undergo great saphenous vein ablation procedures for advanced venous disease and have the least improvement in their symptoms after these procedures. J Vasc Surg Venous Lymphat Disord 2023; 11:904-912.e1. [PMID: 37343786 DOI: 10.1016/j.jvsv.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/29/2023] [Accepted: 06/06/2023] [Indexed: 06/23/2023]
Abstract
OBJECTIVE Chronic venous insufficiency is an increasingly prevalent problem in the United States, with >25 million individuals currently affected. Previous work has shown that racial minorities and low socioeconomic status are associated with a worse clinical presentation and response to treatment. The present study aimed to determine the relationship between race, patient variables, hospital outcomes, and response to treatment for patients presenting for chronic venous insufficiency intervention. METHODS We performed a retrospective analysis of all patients who underwent endovenous ablation (radiofrequency or laser) of the great saphenous vein to treat symptomatic, chronic venous insufficiency using Vascular Quality Initiative data from 2014 to 2020. Patient characteristics and outcomes were analyzed stratified by patient race. The χ2 test and the Kruskal-Wallis equality-of-populations rank test were used to measure the study outcomes. The primary outcomes were an improved venous clinical severity score and improvement in patient-reported outcomes. Patient characteristics, CEAP (clinical, etiologic, anatomic, pathophysiologic) classification, prior venous interventions, length of stay, and time to follow-up were compared between races. RESULTS The database consisted of 9009 predominantly female patients (n = 6041; 67.1%), with a mean age distribution of 56 years. Of the 9009 patients, 7892 are White (87.6%), 627 Hispanic (6.9%), and 490 Black or African American (18.3%). The Hispanic cohort was younger than their White and Black/African American counterparts. Black/African American patients presented with more advanced clinical stages than did the White and Hispanic groups. The clinical stage according to race was as follows: C3-Black/African American, 32.9%; Hispanic, 38.9%; White, 46%; C5-Black/African American, 4.7%; Hispanic, 2.1%; White, 2.3%; and C6-Black/African American, 12.7%; Hispanic, 3.2%; White, 6.2%. Black/African American patients were more likely to present as overweight or obese (66%; P < .001) and less likely to be taking anticoagulation medication preoperatively (11%; P < .001). Non-White race was associated with a higher probability of treatment in the hospital setting (Black/African American, 63.6%; Hispanic, 87.5%; P < .001). Black/African American patients (3.25 ± 4.4; P < .001) demonstrated lower mean improvement postoperatively in both the venous clinical severity score and patient-reported outcomes than their White (4.25 ± 4.13, P <.001) and Hispanic (4.42 ± 3.78; P < .001) counterparts. CONCLUSIONS Differences exist in the clinical severity and symptom presentation based on race. Black/African American patients present with more advanced chronic venous insufficiency than do their White and Hispanic counterparts. Furthermore, the postprocedural analysis showed inferior clinical and self-reported improvement in chronic venous insufficiency for the Black/African American patients. Although the Hispanic population was younger, the White and Hispanic patients experienced similar responses to treatment.

Abstract
BACKGROUND The prevalence of peripheral artery disease (PAD) and leg symptoms are higher in Black than White adults. We studied the effects of self-reported lower extremity symptoms and ankle-brachial indices (ABI) groups on outcomes. METHODS Black participants in the Jackson Heart Study with baseline ABI and PAD symptom assessments (exertional leg pain by the San Diego Claudication questionnaire) were included. Abnormal ABI was < 0.90 or > 1.40. Participants were divided into (1) normal ABI, asymptomatic, (2) normal ABI, symptomatic, (3) abnormal ABI, asymptomatic, and (4) abnormal ABI, symptomatic to examine their associations with MACE (stroke, myocardial infarction, fatal coronary heart disease) and all-cause mortality, using Kaplan-Meier survival curves and stepwise Cox proportional hazard models adjusting for Framingham risk factors. RESULTS Of 4586 participants, mean age was 54.6 ± 12.6 years, with 63% women. Compared with participants with normal ABI who were asymptomatic, participants with abnormal ABI and leg symptoms had highest risk of MACE (adjusted HR 2.28; 95% CI 1.62, 3.22) and mortality (aHR 1.82; 95% CI 1.32, 2.56). Participants with abnormal ABI without leg symptoms had higher risk for MACE (aHR 1.49; 95% CI 1.06, 2.11) and mortality (aHR 1.44; 95% CI 1.12, 1.99). Participants with normal ABI and no leg symptoms did not have higher risks. CONCLUSION Among Black adults, the highest risk for adverse outcomes were in symptomatic participants with abnormal ABIs, followed by asymptomatic participants with abnormal ABIs. These findings underscore the need for further studies to screen for PAD and develop preventative approaches in Black adults with asymptomatic disease.

Abstract
BACKGROUND For individuals with a disability, an increase in functional mobility may improve their quality of life and well-being. Greater understanding is needed on how factors such as gender, geography, and employment may play a role in mobility levels among individuals with lower limb amputation. OBJECTIVES To assess the relationship between gender, geography, and employment status on mobility among lower limb prosthesis users. METHODS A cross-sectional analysis of 7,524 patient mobility outcomes completed across the United States was performed. The regression model included the independent variables, such as age, gender, region, employment status, and amputation level. Mobility was entered as the dependent variable. RESULTS Individuals who were employed had 3.6 times the odds of reaching increased mobility (Prosthetic Limb Users' Survey of Mobility ≥ 50) than those unemployed (odds ratio 3.56, 95% confidence interval 3.10-4.09). Gender and geography were significantly associated with mobility as well. CONCLUSIONS Being employed is associated with greater odds of reaching increased mobility. Addressing factors such as returning to employment may aid in improving mobility levels among prosthesis users.

Abstract
Socio-economic determinants of health (SDoH) include various nonmedical factors in the socio-economic sphere with a potentially significant impact on health outcomes. Their effects manifest through several mediators/moderators (behavioral characteristics, physical environment, psychosocial circumstances, access to care, and biological factors). Various critical covariates (age, gender/sex, race/ethnicity, culture/acculturation, and disability status) also interact. Analyzing the effects of these factors is challenging due to their enormous complexity. Although the significance of SDoH for cardiovascular diseases is well documented, research regarding their impact on peripheral artery disease (PAD) occurrence and care is less well documented. This narrative review explores to what extent SDoH are multifaceted in PAD and how they are associated with its occurrence and care. Additionally, methodological issues that may hamper this effort are addressed. Finally, the most important question, whether this association may contribute to reasonable interventions aimed at SDoH, is analyzed. This endeavor requires attention to the social context, a whole systems approach, multilevel-thinking, and a broader alliance that reaches out to more stakeholders outside the medical sphere. More research is needed to justify the power in this concept to improve PAD-related outcomes like lower extremity amputations. At the present time, some evidence, reasonable consideration, and intuitive reasoning support the implementation of various interventions in SDoH in this field.

Abstract
Patients with chronic kidney disease (CKD) exhibit tremendously elevated risk for cardiovascular disease, particularly ischemic heart disease, due to premature vascular and cardiac aging and accelerated ectopic calcification. The presence of cardiovascular calcification associates with increased risk in patients with CKD. Disturbed mineral homeostasis and diverse comorbidities in these patients drive increased systemic cardiovascular calcification in different manifestations with diverse clinical consequences, like plaque instability, vessel stiffening, and aortic stenosis. This review outlines the heterogeneity in calcification patterning, including mineral type and location and potential implications on clinical outcomes. The advent of therapeutics currently in clinical trials may reduce CKD-associated morbidity. Development of therapeutics for cardiovascular calcification begins with the premise that less mineral is better. While restoring diseased tissues to a noncalcified homeostasis remains the ultimate goal, in some cases, calcific mineral may play a protective role, such as in atherosclerotic plaques. Therefore, developing treatments for ectopic calcification may require a nuanced approach that considers individual patient risk factors. Here, we discuss the most common cardiac and vascular calcification pathologies observed in CKD, how mineral in these tissues affects function, and the potential outcomes and considerations for therapeutic strategies that seek to disrupt the nucleation and growth of mineral. Finally, we discuss future patient-specific considerations for treating cardiac and vascular calcification in patients with CKD-a population in need of anticalcification therapies.

Racial and ethnic disparities in major adverse limb events persist for chronic limb threatening ischemia despite presenting limb threat severity after peripheral vascular intervention. J Vasc Surg 2023; 77:848-857.e2. [PMID: 36334848 DOI: 10.1016/j.jvs.2022.10.043] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 10/14/2022] [Accepted: 10/19/2022] [Indexed: 12/04/2022]
Abstract
OBJECTIVE Racial and ethnic disparities have been well-documented in the outcomes for chronic limb threatening ischemia (CLTI). One purported explanation has been the disease severity at presentation. We hypothesized that the disparities in major adverse limb events (MALE) after peripheral vascular intervention (PVI) for CLTI would persist despite controlling for disease severity at presentation using the WIfI (Wound, Ischemia, foot Infection) stage. METHODS The Vascular Quality Initiative PVI dataset (2016-2021) was queried for CLTI. Patients were excluded if they were missing the WIfI stage. The primary end point was the incidence of 1-year MALE, defined as major amputation (through the tibia or fibula or more proximally) or reintervention (endovascular or surgical) of the initial treatment limb. A multivariate hierarchical Fine-Gray analysis was performed, controlling for hospital variation, competing risk of death, and presenting WIfI stage, to assess the independent association of Black/African American race and Latinx/Hispanic ethnicity with MALE. A Cox proportional hazard regression model was used for the 1-year survival analysis. RESULTS Overall, 47,830 patients (60%) had had WIfI scores reported (73% White, 20% Black, and 7% Latinx). The 1-year unadjusted cumulative incidence of MALE was 13.1% (95% confidence interval [CI], 12.6%-13.5%) for White, 14.3% (95% CI, 13.5%-15.3%) for Black, and 17.0% (95% CI, 15.3%-18.9%) for Latinx patients. On bivariate analysis, the occurrence of MALE was significantly associated with younger age, Black race, Latinx ethnicity, coronary artery disease, cerebrovascular disease, congestive heart failure, hypertension, diabetes, dialysis, intervention level, any prior minor or major amputation, and WIfI stage (P < .001). The cumulative incidence of 1-year MALE increased by increasing WIfI stage: stage 1, 11.7% (95% CI, 10.9%-12.4%); stage 2, 12.4% (95% CI, 11.8%-13.0%); stage 3, 14.8% (95% CI, 13.8%-15.8%); and stage 4, 15.4% (95% CI, 14.3%-16.6%). The cumulative incidence also increased by intervention level: inflow, 10.7% (95% CI, 9.8%-11.7%), femoropopliteal, 12.3% (95% CI, 11.7%-12.9%); and infrapopliteal, 14.1% (95% CI, 13.5%-14.8%). After adjustment for WIfI stage only, Black race (subdistribution hazard ratio [SHR], 1.30; 95% CI, 1.17-1.44; P < .001) and Latinx ethnicity (SHR, 1.58; 95% CI, 1.37-1.81; P < .001) were associated with an increased 1-year hazard of MALE compared with White race. On adjusted multivariable analysis, MALE disparities persisted for Black/African American race (SHR, 1.12; 95% CI, 1.01-1.25; P = .028) and Latinx/Hispanic ethnicity (SHR, 1.34; 95% CI, 1.16-1.54; P < .001) compared with White race. CONCLUSIONS Black/African American and Latinx/Hispanic patients had a higher associated hazard of MALE after PVI for CLTI compared with White patients despite an adjustment for WIfI stage at presentation. These results suggest that disease severity at presentation does not account for disparities in outcomes. Further work should focus on better understanding the underlying mechanisms for disparities in historically marginalized racial and ethnic groups presenting with CLTI.

Abstract
PURPOSE To understand what is known about sex and gender differences in quality of life (QoL) and related domains for individuals with an adult acquired lower limb amputation (LLA). METHODS A computer-assisted literature search of four online databases was completed. Articles were included if they incorporated sex or gender as part of their data analysis with a focus on QoL-related domains. Data were analyzed using descriptive numerical analysis and thematic analysis. RESULTS One hundred and eleven articles were included in this review. Women were under-represented across studies, with most of the participants being men. No articles described the inclusion of trans or non-binary persons. Differences by sex or gender were reported by 66 articles. Articles reporting on gender seldom provided descriptions of how gender was defined. Overall, women/females seemed to have worse outcomes in terms of prosthesis-related outcomes, mental health, and return to occupations. CONCLUSION Articles included in this review were not clear with how gender was defined. In order for more targeted interventions that account for sex and gender differences, studies need to be more forthcoming about how they use and define gender. Future research should seek to include gender non-conforming participants to identify additional needs.Implications for rehabilitationSex and gender are important constructs that influence outcomes following lower limb amputation.Rehabilitation professionals should consider sex and gender-specific outcomes when tailoring programs to ensure ethical clinical care.

Miller TA, Campbell JH, Bloom N, Wurdeman SR. Racial Disparities in Health Care With Timing to Amputation Following Diabetic Foot Ulcer. Diabetes Care 2022; 45:2336-2341. [PMID: 36069831 PMCID: PMC9862414 DOI: 10.2337/dc21-2693] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Accepted: 07/09/2022] [Indexed: 02/05/2023]
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.

Abstract
Introduction The mechanisms for the observed disparities in diabetes-related amputation are poorly understood and could be related to access for diabetic foot ulceration (DFU) care. This qualitative study aimed to understand patients’ personal experiences navigating the healthcare system and the barriers they faced. Methods Fifteen semi-structured interviews were conducted over the phone between June 2020 to February 2021. Participants with DFUs were recruited from a tertiary referral center in Southern Arizona. The interviews were audio-recorded and analyzed according to the NIMHD Research Framework, focusing on the health care system domain. Results Among the 15 participants included in the study, the mean age was 52.4 years (66.7% male), 66.7% was from minority racial groups, and 73.3% was Medicaid or Indian Health Service beneficiaries. Participants frequently reported barriers at various levels of the healthcare system. On the individual level, themes that arose included health literacy and inadequate insurance coverage resulting in financial strain. On the interpersonal level, participants complained of fragmented relationships with providers and experienced challenges in making follow-up appointments. On the community level, participants reported struggles with medical equipment. On the societal level, participants also noted insufficient preventative foot care and education before DFU onset, and many respondents experienced initial misdiagnoses and delays in receiving care. Conclusions Patients with DFUs face significant barriers in accessing medical care at many levels in the healthcare system and beyond. These data highlight opportunities to address the effects of diabetic foot complications and the inequitable burden of inadequately managed diabetic foot care.

Abstract
Purpose
There is limited qualitative research on the experience of patients undergoing lower limb amputation due to chronic limb threatening ischemia (CLTI) and their participation in amputation-level decisions. This study was performed to understand patient lived experiences related to amputation and patient involvement in shared decision making.
Materials and methods
Phenomenological interviews were conducted with Veterans 6–12 months post transtibial or transmetatarsal amputation due to CLTI. Interviews were read and summarized by two analysts who discussed the contents of each interview and relationships between interviews to identify emergent, cross-cutting elements of patient experience.
Results
Twelve patients were interviewed between March and August 2019. Three cross cutting elements of patient lived experience and participation in shared decision making were identified: 1) Lacking a sense of decision making; 2) Actively working towards recovery as response to a perceived loss of independence; and 3) Experiencing amputation as a Veteran.
Conclusions
Patients did not report a high level of involvement in shared decision making about their amputation or amputation level. Understanding patient experiences and priorities is crucial to supporting shared decision making for Veterans with amputation due to CLTI.

Abstract
Over 200 million individuals worldwide are estimated to have peripheral artery disease (PAD). Although the term peripheral can refer to any outer branch of the vasculature, the focus of this review is on lower-extremity arteries. The initial sequelae of PAD often include movement-induced cramping pain in the hips and legs or loss of hair and thinning of the skin on the lower limbs. PAD progresses, sometimes rapidly, to cause nonhealing ulcers and critical limb ischemia which adversely affects mobility and muscle tone; acute limb ischemia is a medical emergency. PAD causes great pain and a high risk of amputation and ultimately puts patients at significant risk for major adverse cardiovascular events. The negative impact on patients' quality of life, as well as the medical costs incurred, are huge. Atherosclerotic plaques are one cause of PAD; however, emerging clinical data now shows that nonatherosclerotic medial arterial calcification (MAC) is an equal and distinct contributor. This ATVB In Focus article will present the recent clinical findings on the prevalence and impact of MAC in PAD, discuss the known pathways that contribute specifically to MAC in the lower extremity, and highlight gaps in knowledge and tools that limit our understanding of MAC pathogenesis.

Abstract
Importance It is not known whether implementation of Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) was associated with improvements in the outcomes among racial and ethnic minority adults at risk of diabetes-related major amputations. Objective To explore the association of early Medicaid expansion with outcomes of diabetic foot ulcerations (DFUs). Design, Setting, and Participants This cohort study included hospitalizations for DFUs among African American, Asian and Pacific Islander, American Indian or Alaska Native, and Hispanic adults as well as adults with another minority racial or ethnic identification aged 20 to 64 years. Data were collected from the State Inpatient Databases for 19 states and the District of Columbia for 2013 to the third quarter of 2015. The analysis was performed on December 4, 2019, and updated on November 9, 2021. Exposures States were categorized into early-adopter states (expansion by January 2014) and nonadopter states. Main Outcomes and Measures Poisson regression was performed to examine the associations of state type, time, and their combined association with the proportional changes of major amputation rate per year per 100 000 population. Results Among the 115 071 hospitalizations among racial and ethnic minority adults with DFUs (64% of sample aged 50 to 64 years; 35%, female; 61%, African American; 25%, Hispanic; 14%, other racial and ethnic minority group), there were 36 829 hospitalizations (32%) for Medicaid beneficiaries and 10 500 hospitalizations (9%) for uninsured patients. Hospitalizations increased 3% (95% CI, 1% to 5%) in early-adopter states and increased 8% (95% CI, 6% to 10%) in nonadopter states after expansion, a significant difference (P for interaction < .001). Although there was no change in the amputation rate (0.08%; 95% CI, -6% to 7%) in early-adopter states after expansion, there was a 9% (95% CI, 3% to 16%) increase in nonadopter states, a significant change (P = .04). For uninsured adults, the amputation rate decreased 33% (95% CI, 10% to 50%) in early-adopter states and did not change (12%; 95% CI, -10% to 38%) in nonadopter states after expansion, a significant difference (P = .006). There was no difference in the change of amputation rate among Medicaid beneficiaries between state types after expansion. Conclusions and Relevance This study found a relative improvement in the major amputation rate among African American, Hispanic, and other racial and ethnic minority adults in early-expansion states compared with nonexpansion states, which could be because of the recruitment of at-risk uninsured adults into the Medicaid program during the first 2 years of ACA implementation. Future study is required to evaluate the long-term association of Medicaid expansion and the rates of amputation.

Abstract
Peripheral artery disease (PAD) is a prevalent condition that confers substantial morbidity and mortality and remains underdiagnosed as well as undertreated in the overall population. Although PAD prevalence is similar or higher in women compared with men, associations of traditional and nontraditional risk factors with PAD and clinical manifestations of PAD differ by sex and may contribute to delayed or lack of diagnosis in women. Such sex-based differences in the manifestation of PAD may arise from sexual dimorphism in the vascular substrate in health as well as sex variation in the responses to vascular stressors. Despite the availability of proven therapies for improving symptoms and reducing risk of ischemic cardiovascular and limb events among patients with diagnosed PAD, important sex differences in treatment and outcomes have been observed. We provide an overview of current knowledge regarding sex differences in the epidemiology, pathophysiology, clinical presentation, and management of PAD.

Abstract
Atherosclerotic peripheral artery disease (PAD) is associated with functional limitations and an increased risk of poor cardiovascular outcomes. Although men are traditionally viewed at higher risk of PAD than women, the true prevalence and incidence is inconsistent among available reports. Some of this variability is due to differences in PAD-related symptoms among women as well as sex-based differences in diagnostic tests, such as the ankle-brachial index, and it is critical for future epidemiologic studies to account for these differences. Generally, women with PAD experience greater functional impairment and decline then men and are less likely to receive guideline-directed medical therapy. In some settings, women are also more likely to present at later stages of disease and more often undergo lower limb amputation than men. Animal data exploring the biological underpinnings of these sex differences are limited, but several mechanisms have been postulated, including differential plaque morphology, alterations in the immune response, and hormonal variation and protection. Epidemiologic data suggest a link between inflammation and PAD and also reveal sex differences in lipid profiles associated with risk of PAD. In this review, we discuss available data on sex differences in PAD with additional focus on potential biological explanations for these differences. We also emphasize important knowledge gaps in this area, including under-representation of women in PAD clinical trials, to help guide future investigations and eliminate sex disparities in PAD.

Abstract
BACKGROUND Significant disparities in surgical outcomes exist. It is imperative to prepare future doctors to eliminate disparities. Our team of senior medical students developed a surgical clerkship module examining equity in prostate cancer. Student attitudes before and after a facilitated teaching session were assessed. METHODS A surgical equity pilot module was integrated into the core surgical clerkship starting in July 2020. This module was composed of (1) asynchronous preparatory material and (2) a synchronous interactive case discussion regarding disparities in prostate cancer. Discussion sessions were facilitated by upper-level medical students. Participants answered optional anonymous Likert-style and open-ended survey questions before and after the session. Pre- and post-responses were compared. RESULTS One hundred and sixteen students completed the module between July 2020 and January 2021. Pre- and post-survey response rates were 66% and 29%, respectively. At baseline, almost all students (95%) agreed knowledge of disparities would make them a better physician. However, the majority (95%) described their general knowledge of surgical disparities as "nonexistent," "poor," or "average." Most students did not have a framework for assessing causes of surgical disparities (86%) and were not aware of interventions for reducing disparities (90%). After intervention, the majority rated their knowledge of surgical disparities as "good" or "excellent" (71%; P < .001). Most students indicated they had a framework 79%; P < .001) and were aware of effective interventions (62%; P < .001). CONCLUSION We demonstrated a successful pilot of an equity-focused clerkship module. Student attitudes after a single session reflected significant improvement in knowledge of causes and interventions related to surgical disparities. Equity-focused teaching can be incorporated into the surgical clerkship.

Amputations at the transmetatarsal (TM) or transtibial (TT) levels result in greater preservation of function and mobility, whereas transfemoral (TF) amputations typically result in a greater adverse impact. Prior investigations have explored racial/ethnic and regional variation in incident amputation level. This study overcomes some of the methodological limitations seen in prior research through the use of a large national, multiyear veteran sample and by including only those who have undergone an incident amputation. OBJECTIVES (1) Determine if there are national/regional differences in the frequency of incident TF amputation compared with TM and TT amputation, (2) Determine if race/ethnicity and geographic region are associated with incident TF amputation level, and (3) Determine if racial/ethnic disparities of incident TF amputation differ by the presence of diabetes or prior revascularization. DESIGN Retrospective cohort study of veterans undergoing an incident dysvascular lower extremity amputation. SETTING One hundred ten Veterans Affairs (VA) Medical Centers. PARTICIPANTS Seven thousand two hundred ninety-six Veterans undergoing incident unilateral dysvascular lower extremity amputation identified in the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database (2005-2014). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Incident amputation level. RESULTS The White, Black, and Hispanic risk for an incident TF amputation was 31% (n = 1356), 35% (n = 810), and 46% (n = 293), respectively. In the Continental region, Blacks who had not had a prior revascularization were more likely to undergo a TF amputation compared to Whites both with and without diabetes (odds ratio [OR] = 1.4; 95% confidence interval [CI], 1.1, 1.9 and OR = 1.5; 95% CI, 1.1, 2.1, respectively). In the Southeast region, Hispanics compared with Whites were at increased odds of undergoing a TF amputation, irrespective of a diabetes or a prior revascularization (ORs ≥ 2.9). CONCLUSIONS Racial and ethnic disparities exist in choice of proximal compared with distal amputation in specific VA geographic regions.

Abstract
Cardiovascular disease is the leading cause of death in women. Decades of grassroots campaigns have helped to raise awareness about the impact of cardiovascular disease in women, and positive changes affecting women and their health have gained momentum. Despite these efforts, there has been stagnation in the overall reduction of cardiovascular disease burden for women in the past decade. Cardiovascular disease in women remains understudied, under-recognised, underdiagnosed, and undertreated. This Commission summarises existing evidence and identifies knowledge gaps in research, prevention, treatment, and access to care for women. Recommendations from an international team of experts and leaders in the field have been generated with a clear focus to reduce the global burden of cardiovascular disease in women by 2030. This Commission represents the first effort of its kind to connect stakeholders, to ignite global awareness of sex-related and gender-related disparities in cardiovascular disease, and to provide a springboard for future research.

Abstract
BACKGROUND Evidence about sex differences in management and outcomes of critical limb ischemia (CLI) is conflicting. METHODS We identified Fee-For-Service Medicare patients within the 5% enhanced sample file who were diagnosed with new incident CLI between 2015 and 2017. For each beneficiary, we identified all hospital admissions, outpatient encounters and procedures, and pharmacy prescriptions. Outcomes included 90-day mortality and major amputation. RESULTS Incidence of CLI declined from 2.80 (95% CI, 2.72-2.88) to 2.47 (95% CI, 2.40-2.54) per 1000 person from 2015 to 2017, P<0.01. Incidence was lower in women compared with men (2.19 versus 3.11 per 1000) but declined in both groups. Women had a lower prevalence of prescription of any statin (48.4% versus 52.9%, P<0.001) or high-intensity statins (15.3% versus 19.8%, P<0.01) compared with men. Overall, 90-day revascularization rate was 52%, and women were less likely to undergo revascularization (50.1% versus 53.6%, P<0.01) compared with men. Women had a similar unadjusted (9.9% versus 10.3%, P=0.5) and adjusted 90-day mortality (adjusted rate ratio, 0.98 [95% CI, 0.85-1.12], P=0.7) compared with men. Over the study period, unadjusted 90-day mortality remained unchanged for men (10.4% in 2015 to 9.9% in 2017, Pfor trend=0.3), and women (9.5% in 2015 to 10.6% in 2017, Pfor trend=0.2). Men had higher unadjusted (12.9% versus 8.9%, P<0.001) and adjusted risk of 90-day major amputation (adjusted rate ratio, 1.30 [95% CI, 1.14-1.48], P<0.001). One-third of patients with CLI underwent major amputation without a diagnostic angiogram or trial of revascularization in the preceding 90 days regardless of the sex. CONCLUSIONS Women with new incident CLI are less likely to receive statin or undergo revascularization at 90 days compared with men. However, the differences were small. There was no difference in risk of 90-day mortality between both sexes. Graphic Abstract: A graphic abstract is available for this article.

Abstract
PURPOSE OF REVIEW In recent years, there have been advances in the prevention, management, and control of peripheral vascular disease (PVD). There is a trend towards aggressive risk factor modification, noninvasive screening, and endovascular revascularization with surgical approaches reserved only for select cases. This article reviews the different management strategies ranging from pharmacotherapy, revascularization, and rehabilitation with an emphasis on the response of women to these therapies. RECENT FINDINGS Overall, the representation of women in the majority of the published data in this arena remains poor. Studies examining medical therapy and endovascular and surgical revascularization were not designed to address sex disparities. Nevertheless, we dissect these therapies and their relevant randomized trials. The paucity of data investigating the response of women to the different management options makes it difficult to make any evidence-based recommendations. This not only applies to the type of intervention, but also the appropriate timing and risks entailed.

Abstract
We estimated changes in the prevalence of chronic hypertension among pregnant women and evaluated the extent to which changes in obesity and smoking were associated with these trends. We designed a population-based cross-sectional analysis of over 151 million women with delivery-related hospitalizations in the United States, 1970 to 2010. Maternal age, year of delivery (period), and maternal year of birth (birth cohort), as well as race, were examined as risk factors for chronic hypertension. Prevalence rates and rate ratios with 95% CIs of chronic hypertension in relation to age, period, and birth cohort were derived through age-period-cohort models. We also examined how changes in obesity and smoking rates influenced age-period-cohort effects. The overall prevalence of chronic hypertension was 0.63%, with black women (1.24%) having more than a 2-fold higher rate than white women (0.53%; rate ratio, 2.31; 95% CI, 2.30–2.32). In the age-period-cohort analysis, the rate of chronic hypertension increased sharply with advancing age and period from 0.11% in 1970 to 1.52% in 2010 (rate ratio, 13.41; 95% CI, 13.22–13.61). The rate of hypertension increased, on average, by 6% (95% CI, 5–6) per year, with the increase being slightly higher among white (7%; 95% CI, 6%–7%) than black (4%; 95% CI, 3%–4%) women. Adjustments for changes in rates of obesity and smoking were not associated with age and period effects. We observed a substantial increase in chronic hypertension rates by age and period and an over 2-fold race disparity in chronic hypertension rates.

Abstract
BACKGROUND Lower extremity amputation rates associated with peripheral arterial disease in Texas are high and vary disproportionately among different populations. We sought to assess the impact of socioeconomic status and health care resource distribution on the geographic prevalence of lower extremity amputation in Texas counties. MATERIALS AND METHODS We collated 2005-2009 data on all 254 Texas counties. The primary outcome was the number of nontraumatic lower extremity amputations. Population-adjusted regressions identified factors that could explain increasing amputation rates. RESULTS We identified 33 counties with population-weighted amputation rates in the highest 25%. These counties had higher rates of diabetes, larger populations of people categorized as black, fewer health care resources, and lower health care utilization. In the presence of more emergency room visits, dual Medicare/Medicaid eligibility decreased total amputations. In counties with more than 70% rural communities, additional primary care providers also significantly decreased amputations per 100,000 residents (mean difference = -0.12, 95% confidence interval: -0.23, -0.0008). CONCLUSIONS Policy-driven strategic health care resource allocation at the local level may benefit patients in high-need, low-resource areas and promote a reduction in amputations.

Abstract
Objective The purpose of this study was to evaluate the disparities in the outcomes of White, African American (AA) and non-AA minority (Hispanics and Native Americans (NA)), patients admitted in the hospitals with diabetic foot infections (DFIs). Research design and methods The HCUP-Nationwide Inpatient Sample (2002 to 2015) was queried to identify patients who were admitted to the hospital for management of DFI using ICD-9 codes. Outcomes evaluated included minor and major amputations, open or endovascular revascularization, and hospital length of stay (LOS). Incidence for amputation and open or endovascular revascularization were evaluated over the study period. Multivariable regression analyses were performed to assess the association between race/ethnicity and outcomes. Results There were 150,701 admissions for DFI, including 98,361 Whites, 24,583 AAs, 24,472 Hispanics, and 1,654 Native Americans (NAs) in the study cohort. Overall, 45,278 (30%) underwent a minor amputation, 9,039 (6%) underwent a major amputation, 3,151 underwent an open bypass, and 8,689 had an endovascular procedure. There was a decreasing incidence in major amputations and an increasing incidence of minor amputations over the study period (P < .05). The risks for major amputation were significantly higher (all p<0.05) for AA (OR 1.4, 95%CI 1.4,1.5), Hispanic (OR 1.3, 95%CI 1.3,1.4), and NA (OR 1.5, 95%CI 1.2,1.8) patients with DFIs compared to White patients. Hispanics (OR 1.3, 95%CI 1.2,1.5) and AAs (OR 1.2, 95%CI 1.1,1.4) were more likely to receive endovascular intervention or open bypass than Whites (all p<0.05). NA patients with DFI were less likely to receive a revascularization procedure (OR 0.6, 95%CI 0.3, 0.9, p = 0.03) than Whites. The mean hospital length of stay (LOS) was significantly longer for AAs (9.2 days) and Hispanics (8.6 days) with DFIs compared to Whites (8.1 days, p<0.001). Conclusion Despite a consistent incidence reduction of amputation over the past decade, racial and ethnic minorities including African American, Hispanic, and Native American patients admitted to hospitals with DFIs have a consistently significantly higher risk of major amputation and longer hospital length of stay than their White counterparts. Native Americans were less likely to receive revascularization procedures compared to other minorities despite exhibiting an elevated risk of an amputation. Further study is required to address and limit racial and ethnic disparities and to further promote equity in the treatment and outcomes of these at-risk patients.

Abstract
AbstractThe population of Australia is ageing, with women being the primary beneficiaries of this increase in longevity. Increasingly older individuals are being diagnosed with different chronic illnesses such as peripheral arterial disease (PAD) which causes blockages of the blood vessels in the legs resulting in pain, non-healing ulcers, immobility and the potential amputation of the threatened limb. PAD has been traditionally thought to affect men more than women. Resultingly, women have been under-represented in clinical trials of PAD and under-diagnosed in the health-care setting. However, it has recently been acknowledged that women are indeedmorelikely to suffer from PAD than men due to increased presence of disease and survival advantage. As such, very little is known about women's understanding of and the meaning they create of their experiences of PAD. Therefore, how older women with PAD experience the ageing process is the focus of this qualitative research project. Interviews were conducted with 11 women from Sydney, Australia aged over 65 years who had been diagnosed with PAD. The interviews were analysed using an inductive thematic analysis. Three manifest themes were constructed: independence and control, active and involved, and the acceptance of ageing. These findings emphasised the idea that despite the presence of a chronic illness and increased age, remaining independent and engaged with life was vital to these women's wellbeing. Their subjective experiences of ageing reflect the fact that by adapting to the physical, mental and social changes that come with growing older, the focus does not need to be on loss and decline but rather can be about the continuation of life that can be both positive and meaningful.

Abstract
OBJECTIVE The objective of this study was to determine whether blacks with lower extremity peripheral artery disease (PAD) have faster functional decline than whites with PAD. METHODS Participants with ankle-brachial index <0.90 were identified from Chicago medical centers and observed longitudinally. Mobility impairment and the 6-minute walk were assessed at baseline and every 6 to 12 months. Mobility loss was defined as becoming unable to walk up and down a flight of stairs or to walk ¼ mile without assistance. RESULTS Of 1162 PAD participants, 305 (26%) were black. Median follow-up was 46.0 months. Among 711 PAD participants who walked 6 minutes continuously at baseline, black participants were more likely to become unable to walk 6 minutes continuously during follow-up (64/171 [37.4%] vs 156/540 [28.9%]; log-rank, P = .006). Black race was associated with becoming unable to walk 6 minutes continuously, adjusting for age, sex, ankle-brachial index, comorbidities, and other confounders (hazard ratio, 1.45; 95% confidence interval, 1.05-1.99; P = .022). This association was attenuated after adjustment for income and education (P = .229). Among 844 participants without baseline mobility impairment, black participants had a higher rate of mobility loss (64/209 [30.6%] vs 164/635 [25.8%]; log-rank, P = .009). Black race was associated with increased mobility loss, adjusting for potential confounders (hazard ratio, 1.42; 95% confidence interval, 1.04-1.94; P = .028). This association was attenuated after additional adjustment for income and education (P = .392) and physical activity (P = .113). There were no racial differences in average annual declines in 6-minute walk, usual-paced 4-meter walking velocity, or fast-paced 4-meter walking velocity. CONCLUSIONS Black PAD patients have higher rates of mobility loss and becoming unable to walk for 6 minutes continuously. These differences appear related to racial differences in socioeconomic status and physical activity.

Abstract
Introduction: Intervention for advanced chronic venous insufficiency is considered an appropriate standard of care. However, outcomes vary among patients who present in advanced clinical stages of disease. The main objectives of this study were to determine whether racial disparity exists at initial presentation and response to intervention. Methods: A retrospective database was created to include all radiofrequency ablation procedures performed by a single surgeon from January 14, 2009, through May 25, 2011. Demographics, clinical traits, race, procedure, and outcomes were analyzed. Stepwise model selection reduced candidate baseline factors to a final parsimonious model, which was analyzed using analysis of variance. Results: The database consisted of 300 patients with a predominant female (n = 215, 85%) base and 85 (15%) males, with a mean age distribution of 53 years. The mean body mass index was 30.2. Racial distribution revealed Asian (n = 9, 3.3%), Pacific Islander (n = 1, 0.4%), African American (n = 37, 13.6%), and Caucasian (CAU, n = 225, 82.7%). African Americans presented with more advanced clinical stages than the CAU group—C2: African American 21.6%, CAU 36.7%; C4: African American 35%, CAU 24.3%; and C6: African American 35.1%, CAU 7.5%. African Americans demonstrated a higher preoperative venous clinical severity score (VCSS) than their CAU counterparts. Postprocedural decrease in VCSS score was lower in African Americans than their CAU counterparts. Conclusion: African American patients present with more advanced venous insufficiency than CAUs. Postprocedural analysis reveals not only slower ulcer healing times but also higher ulcer recurrence rates.

The development and validation of the AMPREDICT model for predicting mobility outcome after dysvascular lower extremity amputation. J Vasc Surg 2016; 65:162-171.e3. [PMID: 27751738 DOI: 10.1016/j.jvs.2016.08.078] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Accepted: 08/19/2016] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The objective of this study was the development of AMPREDICT-Mobility, a tool to predict the probability of independence in either basic or advanced (iBASIC or iADVANCED) mobility 1 year after dysvascular major lower extremity amputation. METHODS Two prospective cohort studies during consecutive 4-year periods (2005-2009 and 2010-2014) were conducted at seven medical centers. Multiple demographic and biopsychosocial predictors were collected in the periamputation period among individuals undergoing their first major amputation because of complications of peripheral arterial disease or diabetes. The primary outcomes were iBASIC and iADVANCED mobility, as measured by the Locomotor Capabilities Index. Combined data from both studies were used for model development and internal validation. Backwards stepwise logistic regression was used to develop the final prediction models. The discrimination and calibration of each model were assessed. Internal validity of each model was assessed with bootstrap sampling. RESULTS Twelve-month follow-up was reached by 157 of 200 (79%) participants. Among these, 54 (34%) did not achieve iBASIC mobility, 103 (66%) achieved at least iBASIC mobility, and 51 (32%) also achieved iADVANCED mobility. Predictive factors associated with reduced odds of achieving iBASIC mobility were increasing age, chronic obstructive pulmonary disease, dialysis, diabetes, prior history of treatment for depression or anxiety, and very poor to fair self-rated health. Those who were white, were married, and had at least a high-school degree had a higher probability of achieving iBASIC mobility. The odds of achieving iBASIC mobility increased with increasing body mass index up to 30 kg/m2 and decreased with increasing body mass index thereafter. The prediction model of iADVANCED mobility included the same predictors with the exception of diabetes, chronic obstructive pulmonary disease, and education level. Both models showed strong discrimination with C statistics of 0.85 and 0.82, respectively. The mean difference in predicted probabilities for those who did and did not achieve iBASIC and iADVANCED mobility was 33% and 29%, respectively. Tests for calibration and observed vs predicted plots suggested good fit for both models; however, the precision of the estimates of the predicted probabilities was modest. Internal validation through bootstrapping demonstrated some overoptimism of the original model development, with the optimism-adjusted C statistic for iBASIC and iADVANCED mobility being 0.74 and 0.71, respectively, and the discrimination slope 19% and 16%, respectively. CONCLUSIONS AMPREDICT-Mobility is a user-friendly prediction tool that can inform the patient undergoing a dysvascular amputation and the patient's provider about the probability of independence in either basic or advanced mobility at each major lower extremity amputation level.

Humphries MD, Brunson A, Li CS, Melnikow J, Romano PS. Amputation trends for patients with lower extremity ulcers due to diabetes and peripheral artery disease using statewide data. J Vasc Surg 2016; 64:1747-1755.e3. [PMID: 27670653 DOI: 10.1016/j.jvs.2016.06.096] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2016] [Accepted: 06/04/2016] [Indexed: 12/17/2022]
Abstract
OBJECTIVE This study reports all-payer amputation rates using state-based administrative claims data for high-risk patients with lower extremity (LE) ulcers and concomitant peripheral artery disease (PAD), diabetes mellitus (DM), or combination PAD/DM. In addition, we characterize patient factors that affect amputation-free survival. We also attempted to create a measure of a patient's ability to manage chronic diseases or to access appropriate outpatient care for ulcer management by accounting for hospital and emergency department (ED) visits in the preceding 60 days to determine how this also affects amputation-free survival. METHODS Patients admitted to nonfederal hospitals, seen in an ED, or treated in an eligible ambulatory surgery center within California from 2005 through 2013 with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a disease-specific LE ulcer were identified in the California Office of Statewide Health Planning and Development database. All subsequent hospital, ED, and ambulatory surgery center visits and procedures are captured to identify whether a patient underwent major amputation. Yearly amputation rates were determined to analyze trends. Amputation-free survival for the PAD, DM, and PAD/DM groups was determined. Cox modeling was used to evaluate the effect of patient characteristics. RESULTS There were 219,547 patients identified with an incident LE ulcer throughout the state. Of these, 131,731 were DM associated, 36,193 were PAD associated, and 51,623 were associated with both PAD and DM. From 2005 to 2013, the number of patients with LE ulcers who required inpatient admission, presented to the ED, or had outpatient procedures was stable. However, there was a statistically significant increase in overall disease-associated amputation rates from 5.1 in 2005 to 13.5 in 2013 (P < .001). Patients with PAD/DM had the greatest increase in amputation rates from 10 per 100 patients with LE ulcers in 2005 to 28 per 100 patients in 2013 (P < .001). Despite that patients with PAD/DM were 8 years younger than patients with PAD only, they had similar amputation-free survival. Within all age groups, men had worse amputation-free survival than women did. Race did not predict amputation-free survival, but having multiple prior ED or hospital admissions was a significant predictor of worse amputation-free survival. CONCLUSIONS Potentially preventable amputations associated with high-risk diseases are increasing among patients who require inpatient hospital admission, present to the ED, or require outpatient interventional treatment. This trend is most notable among patients with a combination of PAD and DM. Patients with repeated hospitalizations before admission for the LE ulcer had the highest risk of amputation.
