RESUMEN
OBJECTIVES: A growing body of data indicates that extracranial carotid artery disease (ECAD) can contribute to cognitive impairment. However, there have been mixed reports regarding the benefit of carotid endarterectomy (CEA) as it relates to preserving cognitive function. In this work, diffusion magnetic resonance imaging (dMRI) and neurocognitive testing are used to provide insight into structural and functional brain changes that occur in subjects with significant carotid artery stenosis, as well as changes that occur in response to CEA. MATERIALS AND METHODS: The study design was a prospective, non-randomized, controlled study that enrolled patients with asymptomatic carotid stenosis. Thirteen subjects had severe ECAD (≥70% stenosis in at least one carotid artery) and were scheduled to undergo surgery. Thirteen had asymptomatic ECAD with <70% stenosis, therefore not requiring surgery. All subjects underwent neurocognitive testing using the Montreal Cognitive Assessment test (MoCA) and high angular resolution, multi-shell diffusion magnetic resonance imaging (dMRI) of the brain at baseline and at four-six months follow-up. Changes in MoCA scores as well as in Fractional anisotropy (FA) along the hippocampus were compared at baseline and follow-up. RESULTS: At baseline, FA was significantly lower along the ipsilateral hippocampus in subjects with severe ECAD compared to subjects without severe ECAD. MoCA scores were lower in these individuals, but this did not reach statistical significance. At follow-up, MoCA scores increased significantly in subjects who underwent CEA and remained statistically equal in control subjects that did not have CEA. FA remained unchanged in the CEA group and decreased in the control group. CONCLUSIONS: This study suggests that CEA improves cognition and preserves hippocampal white matter structure compared to control subjects not undergoing CEA.
RESUMEN
BACKGROUND: Racial disparities exist in access to health care and management of multiple health conditions including chronic pain; however, racial disparities in pre- and postoperative pain management in lower extremity amputation are not well-studied. Our objective was to examine the association between different racial and ethnic groups and prescription opioid and other analgesics use before and after lower extremity amputation. We hypothesize prescription opioid and other analgesic use among Black, Hispanic, and Native American US Medicare beneficiaries undergoing lower extremity amputations will be lower compared to White US Medicare beneficiaries. METHODS: This retrospective cohort study included a 5% national sample of all Medicare beneficiaries from 2011 to 2015 and 15% national sample of fee-for-service Medicare beneficiaries from 2016 to 2018 undergoing nontraumatic, lower extremity amputations. The exposure of interest was racial and ethnic group membership (ie, Black, Hispanic, Native American, White, and others-with others being the combination of the categories Asian and other) as provided in Medicare claims data. Using multivariable generalized estimating equations with a logistic link to account for repeated measurements over time, we estimated the odds of prescription opioid use within 6 months before and after lower extremity amputation across different racial and ethnic groups separately, adjusting for sociodemographic and health status factors (eg, Elixhauser index). Adjusted odds ratios (aORs) and 95% confidence intervals (95% CI) were reported. RESULTS: Among 16,068 eligible beneficiaries who underwent major and minor amputations (mean age = 65.1 ± 12.7 years; female = 36.1%), 10,107 (62.9%) were White, 3462 (21.5%) were Black, 1959 (12.2%) were Hispanic, 247 (1.5%) were Native American, and 151 (2.9%) were beneficiaries of other races. During the 6 months before lower extremity amputation, Hispanic beneficiaries (aOR, 0.71, 95% CI, 0.65-0.78) and beneficiaries of other races (aOR, 0.60, 95% CI, 0.47-0.76) had significantly lower odds of using prescription opioids compared to White beneficiaries. Similarly, Hispanic beneficiaries (aOR, 0.78, 95% CI, 0.71-0.84) and beneficiaries of other races (aOR, 0.63, 95% CI, 0.51-0.78) were associated with lower odds of opioid use in the 6 months after amputation compared to White beneficiaries. CONCLUSIONS: Among fee-for-service Medicare beneficiaries, Hispanic and other (eg, Asian) fee-for-service Medicare beneficiaries had lower odds of prescription opioid use than their White counterparts before and after nontraumatic, lower extremity amputations. Efforts to determine the underlying reasons are needed to ensure equitable health care access.

RESUMEN
BACKGROUND: The purpose of this study was to determine the association of preulcerative foot care and outcomes of diabetic foot ulcerations (DFUs). METHODS: This retrospective cohort study using the Mariner all-payers claims data set included participants with a new DFU from 2010 to 2019. Patients were stratified into two cohorts (foot care and control) based on whether they had received any outpatient foot care within 12 months before DFU. Adjusted comparison was performed by propensity matching for age, sex, and the Charlson Comorbidity Index (1:2 ratio). Kaplan-Meier estimates and logistic regression examined the association between foot care and outcomes of DFUs. RESULTS: Of the 307,131 patients in the study cohort, 4.7% (n = 14,477) received outpatient preulcerative foot care within the 12-month period before DFU. The rate of major amputation was 1.8% (foot care, 1.2%), and 9.0% of patients had hospitalizations for foot infection within 12 months after DFU (foot care, 7.8%). In the study cohort, patients who received pre-DFU foot care had greater major amputation-free survival (P < .001) on Kaplan-Meier estimate. In both the study and matched cohorts, multivariable analysis demonstrated that foot care was associated with lower odds of major amputation for both study (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.48-0.66) and matched (OR, 0.61; 95% CI, 0.51-0.72) cohorts, and lower odds of hospitalizations for a foot infection in both study (OR, 0.91; 95% CI, 0.86-0.96) and matched (OR, 0.88, 95% CI, 0.82-0.94) cohorts. CONCLUSIONS: Among patients with a new DFU, those who received outpatient preulcerative foot care within 12 months of diagnosis had lower risks of major amputation and hospitalizations for foot infection.

The physical consequences of peripheral artery disease (PAD) are well established; however, the impact of comorbid mental health disorders such as depression and anxiety are not well understood. The impact of psychological stress is not only associated with worse perioperative morbidity and mortality but also with a physiologic cascade that accelerates plaque formation. Increasing screening to identify and subsequently treat comorbid mental health disorders is an integral next step in improving outcomes in PAD management. Failure to adequately address social and psychological impact on PAD patients will further widen the gap in disparities faced by high-risk and disenfranchised populations. Integration of mental health professionals, addiction specialists, and community navigators into multidisciplinary care teams can bolster support for PAD patients and improve outcomes.

OBJECTIVE: The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice. The objective of this study is to analyze the impact of the COVID-19 pandemic on surgical delays and adverse outcomes for patients with chronic venous disease scheduled to undergo elective operations. METHODS: The Vascular Surgery COVID-19 Collaborative (VASCC) was founded in March 2020 to evaluate the outcomes of patients with vascular disease whose operations were delayed. Modules were developed by vascular surgeon working groups and tested before implementation. A data analysis of outcomes of patients with chronic venous disease whose surgeries were postponed during the COVID-19 pandemic from March 2020 through February 2021 was performed for this study. RESULTS: A total of 150 patients from 12 institutions in the United States were included in the study. Indications for venous intervention were: 85.3% varicose veins, 10.7% varicose veins with venous ulceration, and 4.0% lipodermatosclerosis. One hundred two surgeries had successfully been completed at the time of data entry. The average length of the delay was 91 days, with a median of 78 days. Delays for venous ulceration procedures ranged from 38 to 208 days. No patients required an emergent intervention due to their venous disease, and no patients experienced major adverse events following their delayed surgeries. CONCLUSIONS: Interventions may be safely delayed for patients with venous disease requiring elective surgical intervention during the COVID-19 pandemic. This finding supports the American College of Surgeons' recommendations for the management of elective vascular surgical procedures. Office-based labs may be safe locations for continued treatment when resources are limited. Although the interventions can be safely postponed, the negative impact on quality of life warrants further investigation.
RESUMEN
Importance: Patients with kidney failure have an increased risk of diabetes-related foot complications. The benefit of regular foot and ankle care in this at-risk population is unknown. Objective: To investigate foot and ankle care by podiatrists and the outcomes of diabetic foot ulcers (DFUs) in patients with kidney failure. Design, Setting, and Participants: This retrospective cohort study included Medicare beneficiaries with type 2 diabetes receiving dialysis who had a new DFU diagnosis. The analysis of the calendar year 2016 to 2019 data from the United States Renal Data System was performed on June 15, 2023, with subsequent updates on December 11, 2023. Exposures: Foot and ankle care by podiatrists during 3 months prior to DFU diagnosis. Main Outcomes and Measures: The outcomes were a composite of death and/or major amputation, as well as major amputation alone. Kaplan-Meier analysis was used to estimate 2 to 3 years of amputation-free survival. Foot and ankle care by podiatrists and the composite outcome was examined using inverse probability-weighted Cox regression, while competing risk regression models were used for the analysis of amputation alone. Results: Among the 14â¯935 adult patients with kidney failure and a new DFU (mean [SD] age, 59.3 [12.7] years; 35.4% aged ≥65 years; 8284 men [55.4%]; Asian, 2.7%; Black/African American, 35.0%; Hispanic, 17.7%; White, 58.5%), 18.4% (n = 2736) received care by podiatrists in the 3 months before index DFU diagnosis. These patients were older, more likely to be male, and have more comorbidities than those without prior podiatrist visits. Over a mean (SD) 13.5 (12.0)-month follow-up, 70% of those with podiatric care experienced death and/or major amputation, compared with 74% in the nonpodiatric group. Survival probabilities at 36 months were 26.3% vs 22.8% (P < .001, unadjusted Kaplan-Meier survival analysis). In multivariate regression analysis, foot and ankle care was associated with an 11% lower likelihood of death and/or amputation (hazard ratio [HR], 0.89 95% CI, 0.84-0.93) and a 9% lower likelihood of major amputation (above or below knee) (HR, 0.91; 95% CI, 0.84-0.99) than those who did not. Conclusions and Relevance: The findings of this study suggest that patients with kidney failure at risk for DFUs who receive foot and ankle care from podiatrists may be associated with a reduced likelihood of diabetes-related amputations.

RESUMEN
INTRODUCTION: Frailty, a predictor of poor outcomes, has been widely studied as a screening tool in surgical decision-making. However, the impact of frailty on the outcomes after fenestrated-branched endovascular aortic repairs (FBEVARs) is less well established. In addition, the changes in frailty during recovery after FBEVAR are unknown. We aim to assess the impact of frailty on outcomes of high-risk patients undergoing physician-modified FBEVARs for complex abdominal and thoracoabdominal aortic aneurysms, as well as the changes in frailty during follow-up. METHODS: Consecutive patients enrolled in a single-center prospective Physician-Sponsored Investigational Device Exemption protocol (FDA# G200159) were evaluated. In addition to the baseline characteristics, frailty was assessed using the Hopkins Frailty Score (HFS) and frailty index (FI) measured by the Frailty Meter. Sarcopenia was measured by L3 total psoas muscle area (PMA). These measurements were repeated during follow-up. The follow-up HFS and FI were compared with baseline scores using the Wilcoxon signed-rank test, whereas follow-up PMA measurements were compared with the baseline using the paired t test. The association between baseline frailty and morbidity was evaluated by the Wilcoxon rank-sum test. RESULTS: Seventy patients were analyzed in a prospective Physician-Sponsored Investigational Device Exemption study from February 9, 2021, to June 2, 2023. At baseline, HFS identified 54% of patients as not frail, 43% as intermediately frail, and 3% as frail. Technical success of FBEVAR was 94% with one in-hospital mortality. Early major adverse events were seen in 10 (14.3%) patients. No difference in baseline FI was seen between patients with early morbidity and those without. Patients who were not frail per HFS were less likely to experience early morbidity (P = .033), and there was a significantly lower baseline PMA in patients who experienced early morbidity (P = .016). At 1 month, patients experienced a significant increase in HFS and HFS category (P = .001 and P = .01) and a significant decrease in sarcopenia (mean PMA: -96 mm2, P = .005). At 6 months, HFS and HFS category as well as PMA returned toward baseline (P = .42, P = .38, and mean PMA: +4 mm2, P = .6). CONCLUSIONS: Preoperative frailty and sarcopenia were associated with early morbidity after physician-modified FBEVAR. During follow-up, patients became more frail and sarcopenic by 1 month. Recovery from this initial decline was seen by 6 months, suggesting that frailty and sarcopenia are reversible processes rather than a unidirectional phenomenon of continued decline.

BACKGROUND: Increasing social vulnerability, measured by the Social Vulnerability Index, has been associated with worse surgical outcomes. However, less is known about the impact of social vulnerability on patients who underwent colorectal surgery under enhanced recovery programs. OBJECTIVE: We hypothesized that increasing social vulnerability is associated with worse outcomes before enhanced recovery implementation, but that after implementation, disparities in outcomes would be reduced. DESIGN: Retrospective cohort study using multivariable logistic regression to identify associations of social vulnerability and enhanced recovery with outcomes. SETTINGS: Institutional American College of Surgeons National Surgical Quality Improvement Program database. PATIENTS: Patients undergoing elective colorectal surgery (2010-2020). Enhanced recovery programs were implemented in 2015. Those adhering to 70% or more of enhanced recovery program components were defined as enhanced recovery and all others as nonenhanced recovery. OUTCOMES: Length of stay, complications, and readmissions. RESULTS: Of 1523 patients, 589 (38.7%) were in the enhanced recovery group, with 625 patients (41%) in the lowest third of the Social Vulnerability Index, 411 (27%) in the highest third. There were no differences in Social Vulnerability Index distribution by the enhanced recovery group. On multivariable modeling, social vulnerability was not associated with increased length of stay, complications, or readmissions in the enhanced recovery group. Black race was associated with increased length of stay in both the nonenhanced recovery (OR 1.2; 95% CI, 1.1-1.3) and enhanced recovery groups (OR 1.2; 95% CI, 1.1-1.4). Enhanced recovery adherence was associated with reductions in racial disparities in complications as the Black race was associated with increased odds of complications in the nonenhanced recovery group (OR 1.9; 95% CI, 1.2-3.0) but not in the enhanced recovery group (OR 0.8; 95% CI, 0.4-1.6). LIMITATIONS: Details of potential factors affecting enhanced recovery program adherence were not assessed and are the subject of current work by this team. CONCLUSION: High social vulnerability was not associated with worse outcomes among both enhanced recovery and nonenhanced recovery colorectal patients. Enhanced recovery program adherence was associated with reductions in racial disparities in complication rates. However, disparities in length of stay remain, and work is needed to understand the underlying mechanisms driving these disparities. See Video Abstract . COMPRENDIENDO EL IMPACTO DE LOS PROGRAMAS DE RECUPERACIN MEJORADA EN LA VULNERABILIDAD SOCIAL, LA RAZA Y LOS RESULTADOS DE LA CIRUGA COLORRECTAL: ANTECEDENTES:El aumento de la vulnerabilidad social medida por el índice de vulnerabilidad social se ha asociado con peores resultados quirúrgicos. Sin embargo, se sabe menos sobre el impacto de la vulnerabilidad social en los pacientes de cirugía colorrectal bajo programas de recuperación mejorados.OBJETIVO:Planteamos la hipótesis de que el aumento de la vulnerabilidad social se asocia con peores resultados antes de la implementación de la recuperación mejorada, pero después de la implementación, las disparidades en los resultados se reducirían.DISEÑO:Estudio de cohorte retrospectivo que utilizó regresión logística multivariable para identificar asociaciones de vulnerabilidad social y recuperación mejorada con los resultados.ESCENARIO:Base de datos institucional del Programa de Mejora Nacional de la Calidad de la Cirugía del American College of Surgeons.PACIENTES:Pacientes sometidos a cirugía colorrectal electiva (2010-2020). Programas de recuperación mejorada implementados en 2015. Aquellos que se adhieren a ≥70% de los componentes del programa de recuperación mejorada definidos como recuperación mejorada y todos los demás como recuperación no mejorada.MEDIDAS DE RESULTADO:Duración de la estancia hospitalaria, complicaciones y reingresos.RESULTADOS:De 1.523 pacientes, 589 (38,7%) estaban en el grupo de recuperación mejorada, con 732 (40,3%) pacientes en el tercio más bajo del índice de vulnerabilidad social, 498 (27,4%) en el tercio más alto, y no hubo diferencias en la distribución del índice vulnerabilidad social por grupo de recuperación mejorada. En el modelo multivariable, la vulnerabilidad social no se asoció con una mayor duración de la estancia hospitalaria, complicaciones o reingresos en ninguno de los grupos de recuperación mejorada. La raza negra se asoció con una mayor duración de la estadía tanto en el grupo de recuperación no mejorada (OR1,2, IC95% 1,1-1,3) como en el grupo de recuperación mejorada (OR1,2, IC95% 1,1-1,4). La adherencia a la recuperación mejorada se asoció con reducciones en las disparidades raciales en las complicaciones, ya que la raza negra se asoció con mayores probabilidades de complicaciones en el grupo de recuperación no mejorada (OR1,9, IC95% 1,2-3,0), pero no en el grupo de recuperación mejorada (OR0,8, IC95% 0,4-1,6).LIMITACIONES:No se evaluaron los detalles de los factores potenciales que afectan la adherencia al programa de recuperación mejorada y son el tema del trabajo actual de este equipo.CONCLUSIÓN:La alta vulnerabilidad social no se asoció con peores resultados entre los pacientes colorrectales con recuperación mejorada y sin recuperación mejorada. Una mayor adherencia al programa de recuperación se asoció con reducciones en las disparidades raciales en las tasas de complicaciones. Sin embargo, persisten disparidades en la duración de la estadía y es necesario trabajar para comprender los mecanismos subyacentes que impulsan estas disparidades. (Traducción-Dr. Felipe Bellolio ).

BACKGROUND: Community-related health assessments have been shown to improve several outcomes in socioeconomically disadvantaged populations with comorbid chronic health conditions. However, while it is recognized that modifiable social determinant of health (SDH) factors might be responsible for up to 60% of preventable deaths, it is not yet standard of care to routinely screen and address these at preventive health appointments. The objective of this study was to identify the social needs of socioeconomically disadvantaged patients. METHODS: We performed a retrospective review of the socioeconomic screening questionnaires distributed to under- and uninsured patients seen at a medical student-run free primary care-based community clinic. This study included participants of all ages (0 and up), genders, languages, and ethnicities who filled out the social screening questionnaire. Socioeconomic screening questionnaires assessed the need for critical resources such as food, housing, utilities, finances, transportation, childcare, employment, education, legal support, companionship, health literacy, and community assistance. The primary study outcome was to identify unmet social needs of our medical student-run free clinic patients. We secondarily sought to identify associations between these needs and chronic health conditions. We hypothesized that patients with multiple chronic health problems and financial stressors would have the highest requests for resources. RESULTS: Our retrospective review identified 264 uninsured participants who were evaluated for social needs using a screening questionnaire. Participants who reported unmet social needs had significantly more cardiovascular risk factors than those who did not. Cardiovascular comorbidities and a history of psychiatric illness were the two most common medical problems significantly associated with several unmet social needs. CONCLUSION: This study provides support for the preemptive identification and appropriate management of physical, mental, and social care to improve disproportionate disparities in long-term health outcomes.

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.

Importance: Approximately 18.6 million people worldwide are affected by a diabetic foot ulcer each year, including 1.6 million people in the United States. These ulcers precede 80% of lower extremity amputations among people diagnosed with diabetes and are associated with an increased risk of death. Observations: Neurological, vascular, and biomechanical factors contribute to diabetic foot ulceration. Approximately 50% to 60% of ulcers become infected, and about 20% of moderate to severe infections lead to lower extremity amputations. The 5-year mortality rate for individuals with a diabetic foot ulcer is approximately 30%, exceeding 70% for those with a major amputation. The mortality rate for people with diabetic foot ulcers is 231 deaths per 1000 person-years, compared with 182 deaths per 1000 person-years in people with diabetes without foot ulcers. People who are Black, Hispanic, or Native American and people with low socioeconomic status have higher rates of diabetic foot ulcer and subsequent amputation compared with White people. Classifying ulcers based on the degree of tissue loss, ischemia, and infection can help identify risk of limb-threatening disease. Several interventions reduce risk of ulcers compared with usual care, such as pressure-relieving footwear (13.3% vs 25.4%; relative risk, 0.49; 95% CI, 0.28-0.84), foot skin measurements with off-loading when hot spots (ie, greater than 2 °C difference between the affected foot and the unaffected foot) are found (18.7% vs 30.8%; relative risk, 0.51; 95% CI, 0.31-0.84), and treatment of preulcer signs. Surgical debridement, reducing pressure from weight bearing on the ulcer, and treating lower extremity ischemia and foot infection are first-line therapies for diabetic foot ulcers. Randomized clinical trials support treatments to accelerate wound healing and culture-directed oral antibiotics for localized osteomyelitis. Multidisciplinary care, typically consisting of podiatrists, infectious disease specialists, and vascular surgeons, in close collaboration with primary care clinicians, is associated with lower major amputation rates relative to usual care (3.2% vs 4.4%; odds ratio, 0.40; 95% CI, 0.32-0.51). Approximately 30% to 40% of diabetic foot ulcers heal at 12 weeks, and recurrence after healing is estimated to be 42% at 1 year and 65% at 5 years. Conclusions and Relevance: Diabetic foot ulcers affect approximately 18.6 million people worldwide each year and are associated with increased rates of amputation and death. Surgical debridement, reducing pressure from weight bearing, treating lower extremity ischemia and foot infection, and early referral for multidisciplinary care are first-line therapies for diabetic foot ulcers.

OBJECTIVE: Anticipated perioperative morbidity is an important factor for choosing a revascularization method for chronic limb-threatening ischemia (CLTI). Our goal was to assess systemic perioperative complications of patients treated with surgical and endovascular revascularization in the Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial. METHODS: BEST-CLI was a prospective randomized trial comparing open (OPEN) and endovascular (ENDO) revascularization strategies for patients with CLTI. Two parallel cohorts were studied: Cohort 1 included patients with adequate single-segment great saphenous vein (SSGSV), whereas Cohort 2 included those without SSGSV. Data were queried for major adverse cardiovascular events (MACE-composite myocardial infarction, stroke, death), non-serious (non-SAEs) and serious adverse events (SAEs) (criteria-death/life-threatening/requiring hospitalization or prolongation of hospitalization/significant disability/incapacitation/affecting subject safety in trial) 30 days after the procedure. Per protocol analysis was used (intervention received without crossover), and risk-adjusted analysis was performed. RESULTS: There were 1367 patients (662 OPEN, 705 ENDO) in Cohort 1 and 379 patients (188 OPEN, 191 ENDO) in Cohort 2. Thirty-day mortality in Cohort 1 was 1.5% (OPEN 1.8%; ENDO 1.3%) and in Cohort 2 was 1.3% (2.7% OPEN; 0% ENDO). MACE in Cohort 1 was 4.7% for OPEN vs 3.13% for ENDO (P = .14), and in Cohort 2, was 4.28% for OPEN and 1.05% for ENDO (P = .15). On risk-adjusted analysis, there was no difference in 30-day MACE for OPEN vs ENDO for Cohort 1 (hazard ratio [HR] 1.5; 95% confidence interval [CI], 0.85-2.64; P = .16) or Cohort 2 (HR, 2.17; 95% CI, 0.48-9.88; P = .31). The incidence of acute renal failure was similar across interventions; in Cohort 1 it was 3.6% for OPEN vs 2.1% for ENDO (HR, 1.6; 95% CI, 0.85-3.12; P = .14), and in Cohort 2, it was 4.2% OPEN vs 1.6% ENDO (HR, 2.86; 95% CI, 0.75-10.8; P = .12). The occurrence of venous thromboembolism was low overall and was similar between groups in Cohort 1 (OPEN 0.9%; ENDO 0.4%) and Cohort 2 (OPEN 0.5%; ENDO 0%). Rates of any non-SAEs in Cohort 1 were 23.4% in OPEN and 17.9% in ENDO (P = .013); in Cohort 2, they were 21.8% for OPEN and 19.9% for ENDO (P = .7). Rates for any SAEs in Cohort 1 were 35.3% for OPEN and 31.6% for ENDO (P = .15); in Cohort 2, they were 25.5% for OPEN and 23.6% for ENDO (P = .72). The most common types of non-SAEs and SAEs were infection, procedural complications, and cardiovascular events. CONCLUSIONS: In BEST-CLI, patients with CLTI who were deemed suitable candidates for open lower extremity bypass surgery had similar peri-procedural complications following either OPEN or ENDO revascularization: In such patients, concern about risk of peri-procedure complications should not be a deterrent in deciding revascularization strategy. Rather, other factors, including effectiveness in restoring perfusion and patient preference, are more relevant.

Aim: To describe patients' reported employment challenges associated with diabetic foot ulcers (DFUs). Methods: Fifteen patients from under-resourced communities in Southern Arizona, with a history of DFUs and/or amputations, were recruited from a tertiary referral center from June 2020 to February 2021. Participants consented to an audio-recorded semi-structured phone interview. Interviews were transcribed and thematically analyzed using the Dedoose data analysis platform. Results: Participants shared a common theme around the cyclic challenges of DFU prevention/management and employment. Those employed in manual labor-intensive jobs or jobs requiring them to be on their feet for long durations of time believed working conditions contributed to the development of their DFUs. Patients reported work incapacity due to declines in mobility and the need to offload for DFU management. Many expressed frustration and emotional distress related to these challenges noting that DFUs resulted in lower remuneration as medical expenses increased. Consequently, loss of income and/or medical insurance often hindered participants' ability to manage DFUs and subsequent complications. Conclusion: These data illuminate the vicious cycle of DFU and employment challenges that must be addressed through patient-centered prevention strategies. Healthcare providers should consider a person's contextual factors such as employment type to tailor treatment approaches. Employers should establish inclusive policies that support patients with DFUs returning to work through flexible working hours and adapted work tasks as needed. Policymakers can also mitigate employment challenges by implementing social programs that provide resources for employees who are unable to return to work in their former capacity.
RESUMEN
BACKGROUND: Peripheral artery disease (PAD) is linked with an increased risk of lower extremity amputation and multiple socioeconomic factors attenuate this risk. Prior studies have demonstrated increased rates of amputation in PAD patients with suboptimal or no insurance coverage. However, the impact of insurance loss in PAD patients with pre-existing commercial insurance coverage is unclear. In this study, we evaluated the outcomes of PAD patients who lose commercial insurance coverage. METHODS: The Pearl Diver all-payor insurance claims database was used to identify adult patients (>18 years) with a PAD diagnosis from 2010 to 2019. The study cohort included patients with pre-existing commercial insurance and at least 3 years continuous enrollment after diagnosis of PAD. Patients were stratified based on whether they had an interruption of commercial insurance coverage over time. Patients who transitioned from commercial insurance to Medicare and other government-sponsored insurance during follow up were excluded. Adjusted comparison (1:1 ratio) was performed using propensity matching for age, gender, the Charlson Comorbidity Index (CCI), and relevant comorbidities. The main outcomes were major amputation and minor amputation. Cox proportional hazards ratios and Kaplan-Meier estimate were used to examine the association between loss of insurance and outcomes. RESULTS: Among the 214,386 patients included, 43.3% (n = 92,772) had continuous commercial insurance coverage and 56.7% (n = 121,614) had interruption of coverage (transition to uninsured or Medicaid coverage) during follow up. In the crude cohort and matched cohort, interruption of coverage was associated with lower major amputation-free survival on Kaplan Meier estimate (P < 0.001). In the crude cohort, interruption of coverage was associated with 77% increased risk of major amputation (OR 1.77, 95% CI 1.49-2.12) and a 41% high risk of minor amputation (OR 1.41, 95% CI 1.31-1.53). In the matched cohort, interruption of coverage was associated with 87% increased risk of major amputation (OR 1.87, 95% CI 1.57-2.25) and a 104% increased risk of minor amputation (OR 1.47, 95% CI 1.36-1.60). CONCLUSIONS: Interruption of insurance coverage in PAD patients with pre-existing commercial health insurance was associated with increased risks of lower extremity amputation.

People with diabetic foot ulcers (DFUs) are commonly prescribed offloading walkers, but inadequate adherence to prescribed use can be a barrier to ulcer healing. This study examined user perspectives of offloading walkers to provide insight on ways to help promote adherence. Participants were randomized to wear: (1) irremovable, (2) removable, or (3) smart removable walkers (smart boot) that provided feedback on adherence and daily walking. Participants completed a 15-item questionnaire based on the Technology Acceptance Model (TAM). Spearman correlations assessed associations between TAM ratings with participant characteristics. Chi-squared tests compared TAM ratings between ethnicities, as well as 12-month retrospective fall status. A total of 21 adults with DFU (age 61.5 ± 11.8 years) participated. Smart boot users reported that learning how to use the boot was easy (ρ =-0.82, p≤ 0.001). Regardless of group, people who identified as Hispanic or Latino, compared to those who did not, reported they liked using the smart boot (p = 0.05) and would use it in the future (p = 0.04). Non-fallers, compared to fallers, reported the design of the smart boot made them want to wear it longer (p = 0.04) and it was easy to take on and off (p = 0.04). Our findings can help inform considerations for patient education and design of offloading walkers for DFUs.
