The current sociopolitical landscape continues to infiltrate our house of surgery, leaving faculty, staff, and learners challenged by uncertainty while introducing downstream interference to cohesive health care delivery for our patients. National surgical associations must cultivate an ethos of unity and intellectual solidarity within the surgical community, thereby reinforcing a foundation for productive and respectful discourse. This is not a call for uniformity in thought but for unity in purpose, action, and mutual respect., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objective: There remains a progressive projected deficit in the vascular surgery (VS) workforce for decades. Despite the expanding integrated VS residency pathway, the fellowship training model remains critical in supporting our future workforce. Therefore, it is imperative to understand the resident and program-specific factors that influence VS specialization among general surgery (GS) residents., Methods: Data from the United States Resident OPerative Experience (ROPE) Consortium, which comprises 20 Accreditation Council for Graduate Medical Education-accredited GS residency programs across the United States, were queried for resident demographics and residency program-related details. Logistic regression analysis was used to identify factors associated with VS specialization., Results: From 2010 to 2020, a total of 1343 graduating GS residents were included in the study. Of these, 135 (10.1%) pursued VS fellowship training. Residents pursuing VS were more frequently male (80.7% vs 62.8%; P < .0001) and younger (median age, 32 vs 33 years; P = .03) compared with other GS residents. Racial and ethnic group, underrepresented in medicine status, and international medical graduate status were similar between the VS and non-VS groups. Residency program-level details were also similar between groups, including program type (university vs community-based), region, size, resident volume, dedicated research experience, and National Institutes of Health funding. Dedicated vascular rotations were common among all GS programs (95.4%), and total months spent on a VS rotation (median, 4 vs 4.5 months; P = .11) did not differ among residents pursuing VS and all other residents. The presence of a collocated traditional (5 + 2) VS fellowship (91.1% vs 90.4%; P = .79) or integrated (0 + 5) VS residency (56.3% vs 55.0%; P = .77) were also similar between groups. On multivariate analysis, only male sex (odds ratio, 2.34; 95% confidence interval, 1.50-3.81; P < .001) was associated with pursuing VS fellowship. Factors that did not impact VS specialization included resident age, underrepresented in medicine status, international medical graduate status, program volume, dedicated research experience, or total months spent on a VS rotation., Conclusions: In this multi-institutional study, we did not find any program-specific factors that influence VS specialization among GS residents. Notably, the presence of a collocated 0 + 5 residency or 5 + 2 fellowship program did not appear to deter GS residents from pursuing a VS fellowship. These data suggest that individual factors, such as mentorship, may be more impactful in recruiting GS residents to the VS specialty., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Background: The restructuring of nonelective general surgery and nationwide implementation of the acute care surgery paradigm has improved patient outcomes and healthcare resource utilization. Although vascular surgery maintains one of the highest acuity rates among surgical specialties, the acute care vascular surgery (ACVS) practice model has not been widely accepted. In the present study, we investigate the scope and burden of ACVS at a tertiary academic medical system., Methods: All vascular surgical procedures performed at three hospitals comprising a large tertiary academic medical system were retrospectively queried through electronic medical records. Data were collected on procedure, acuity, timing of intervention, primary service, admission type, and total costs and charges. Patients were stratified by acuity of surgical intervention, with ACVS being defined as urgent or emergent operation., Results: A total of 12,689 vascular surgeries were performed from 2018 to 2022. ACVS procedures comprised 22.1% of this total (n = 2,803; 12.5% urgent, 9.6% emergent), with an annual burden ranging from 19.1% to 28.3%. Vascular surgeons served as primary surgeon in 91.3% of ACVS and cosurgeon in 8.7%. Fourteen separate surgical specialties requested acute vascular assistance, with the most frequently consulting specialties, including trauma or acute care surgery (ACS) (n = 109, 3.9%) and cardiac surgery (n = 74, 2.6%). ACVS cases were more frequently performed during after-hours (30.7% vs 11.6%) and on weekends (27.1% vs 2.0%) compared with elective vascular procedures (P < 0.0001 each). The majority of ACVS cases originated from inpatient (n = 2,353, 85.0%) and emergency department (n = 379, 13.5%) consultations. Overall, ACVS generated $37.5 million in charges, accounting for 14% of total procedure-related charges over the study period., Conclusions: ACVS comprises a substantial portion of modern vascular practice and is associated with significant human and healthcare resource expenditure. These data support the development of practice models dedicated to acute vascular surgical care., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objective: The Vascular Surgery In-Training Examination (VSITE) is a yearly exam evaluating vascular trainees' knowledge base. Although multiple studies have evaluated variables associated with exam outcomes, few have incorporated training program-specific metrics. The purpose of this study is to evaluate the impact of the learning environment and burnout on VSITE performance., Methods: Data was collected from a confidential, voluntary survey administered after the 2020 to 2022 VSITE as part of the SECOND Trial. VSITE scores were calculated as percent correct then standardized per the American Board of Surgery. Generalized estimating equations with robust standard errors and an independent correlation structure were used to evaluate trainee and program factors associated with exam outcomes. Analyses were further stratified by integrated and independent training paradigms., Results: A total of 1385 trainee responses with burnout data were collected over 3 years (408 in 2020, 459 in 2021, 498 in 2022). On average, 46% of responses reported at least weekly burnout symptoms. On unadjusted analysis, burnout symptoms correlated with a 14 point drop in VSITE score (95% confidence interval [CI], -24 to -4; P = .006). However, burnout was no longer significant after adjusted analysis. Instead, higher postgraduate year level, being in a relationship, identifying as male gender with or without kids, identifying as non-Hispanic white, larger programs, and having a sense of belonging within a program were associated with higher VSITE scores., Conclusions: Despite high rates of burnout, trainees generally demonstrate resilience in gaining the medical knowledge necessary to pass the VSITE. Performance on standardized exams is associated with trainee and program characteristics, including availability of support systems and program belongingness., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Objective: Racial and ethnic disparities have been well-described among surgical specialties; however, variations in underrepresented in medicine (URiM) representation between these specialties have not previously been quantified., Methods: Data collected from Accreditation Council for Graduate Medical Education (ACGME) annual reports were used to derive the Diversity of Surgical Trainee Index (DoSTI), which was calculated as the proportion of URiM residents and fellow physicians within a given surgical specialty, relative to the overall proportion of URiM trainees within all surgical and non-surgical ACGME-accredited programs in the same academic year., Results: From 2013 to 2022, a total of 108,193 ACGME-accredited residency programs trained 1,296,204 residents and fellows in the United States. Of these, 14.1% (n = 182,680) of trainees self-identified as URiM over the study period. The mean DoSTI among all surgical specialties was 0.80 (standard error, 0.01) compared with all ACGME-accredited programs. High DoSTI specialties incorporated significantly higher proportions of trainees who identify as Hispanic (8.7% vs 6.3%) and Black or African American (5.2% vs 2.5%) when compared with low DoSTI specialties (P < .0001 each). General surgery (1.06 ± 0.01), plastic surgery (traditional) (1.12 ± 0.06), vascular surgery (integrated) (0.96 ± 0.03), and vascular surgery (traditional) (0.94 ± 0.06) had the highest DoSTI (P < .05 each vs composite). On linear regression analysis, only ophthalmology (+0.01/year; R 2  = 0.41; P = .019), orthopedic surgery (+0.01/year; R 2  = 0.33; P = .047), otolaryngology (+0.02/year; R 2  = 0.86; P < .001), and pediatric surgery (+0.06/year; R 2  = 0.33; P = .048) demonstrated an annual increase in DoSTI., Conclusions: The DoSTI is a novel metric used to quantify the degree of URiM representation among surgical specialties. DoSTI has revealed specialty-specific variations in racial/ethnic minority representation among surgical training programs. This metric may be used to improve provider awareness and identify high performing DoSTI specialties to highlight best practices to ultimately recruit a more diverse surgical workforce., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Background: Vascular surgeons play a critical role in the functioning of a healthcare system. As a service line, vascular surgery not only performs its own complex operations but also provides support to other surgical specialties by assisting in the management of vascular-related complications. Previous reports have acknowledged the value of consulting vascular surgeons; however, these studies have primarily been limited to single-center series. In this study, we aim to contribute to the existing literature by sharing our experience and highlighting the financial value of consulting vascular surgeons at a large tertiary academic medical center., Methods: Institutional electronic medical records were retrospectively queried for all operations performed by vascular surgeons from 2020 to 2022. Two separate procedural groups were identified. The first group comprised all surgeries where vascular surgery was listed as a co-surgeon for other surgical specialties. The second group comprised all surgeries where vascular surgery was the primary surgeon for service-level cases. Service-level cases were defined as operations resulting directly from (1) iatrogenic complications from other services, (2) consultations for traumatic injury, or (3) primary surgeon for nonvascular cases. The Centers for Medicare and Medicaid Services Physician Fee Schedule was used to calculate work relative value units (wRVUs) per primary procedure code., Results: A total of 7,821 surgeries were performed with vascular involvement more than the study period. Of these, 726 operations (9.3%) were co-surgeon cases requiring intraoperative vascular assistance, from 109 surgeons across all 16 surgical specialties. There were no missing data. The most common specialties requesting vascular assistance included cardiac surgery (n = 247, 34.0%), orthopedic surgery (n = 152, 20.9%), and neurosurgery (n = 131, 18.0%). Total procedural wRVU for co-surgeon cases was 16,220, and total charges exceeded $77.5 million dollars. Vascular surgery served in a primary surgeon role in an additional 154 service-level cases (2.0%) resulting from 10 nonsurgical services. The most common service-level indication was iatrogenic vascular injury (n = 87, 56.4%), and most service-level cases required urgent or emergent surgery (n = 123, 79.9%). These procedures generated an additional 2,150 wRVUs and $1.1 million dollars in charges for the hospital system. Of all co-surgeon or service-level cases, 19.1% (n = 168) occurred after-hours and 10.3% (n = 91) occurred on a holiday or weekend., Conclusions: Vascular surgery is crucial to the operation of all surgical services and many nonsurgical service lines within an academic medical center. Apart from providing essential services for primary vascular diseases, the vascular surgery service line offers substantial financial benefits to the healthcare system through its consulting role. A considerable portion of operative consultations is performed under urgent or emergent circumstances, often necessitating surgical intervention outside regular working hours or on holidays/weekends. These findings have significant implications for assessing the value and compensation of vascular surgeons in today's healthcare landscape., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Surgical site infections (SSIs) are among the most common complications after lower extremity bypass (LEB). Both patient and hospital-related factors have been associated with SSI after LEB; however, the impact of surgical closure technique on SSI incidence remains unclear., Methods: Institutional electronic medical records (EMRs) were retrospectively queried for all LEB procedures performed from 2018 to 2022. Data were collected on patient demographics, medical comorbidities, operative details, wound closure techniques, and postoperative outcomes. Closure techniques included skin staples, absorbable monofilament (Monocryl), nonabsorbable monofilament (Nylon), or left open to heal by secondary intention. Logistic regression analysis was utilized to identify risk factors and calculate adjusted odds ratios (ORs) for postoperative SSI., Results: A total of 517 patients underwent LEB surgery over the study period. SSI was diagnosed in 120 (23.2%) patients over a median follow-up period of 1.5 years. The most common SSI locations were groin incision (40.0%), saphenectomy (31.7%), and leg incision (19.2%). The median onset of SSI was 18.5 d (interquartile range [IQR] 11-28 d) post-LEB surgery. Patients with SSI had higher body mass index (BMI) (28.2 [IQR 24.2-33.5] vs. 26.6 [23.1-31.5] kg/m 2 , P = 0.03) compared with non-SSI patients. Patient age, sex, and medical comorbidities were otherwise similar between groups. There were no differences in closure technique (79.2% vs. 78.1% staples, 18.3% vs. 19.7% Monocryl, 0.8% vs. 1.8% Nylon, 1.7% vs. 0.5% open; P = 0.53) in SSI versus non-SSI groups. On multivariate analysis, patient BMI (OR 1.04 per unit, 95% confidence interval [CI] 1.01-1.08, P = 0.02), reoperative field (OR 1.81, 95% CI 1.00-3.25, P = 0.03), and active smoking (OR 2.72, 95% CI 1.12-6.59, P = 0.048) were independently associated with increased SSI incidence. Postoperative SSI resulted in prolonged hospital length of stay (LOS) (7 vs. 6 days, P = 0.04), unplanned hospital readmission (49.2% vs. 12.3%, P < 0.001), and reoperation rates (64.7% vs. 8.1%, P < 0.001). Bypass graft infection rates were also higher among patients suffering postoperative SSI (9.2% vs. 0.0%, P < 0.001). On subset analysis of patients at increased risk of postoperative SSI, as found on multivariate modeling, there were no differences in closure technique between SSI and no SSI groups., Conclusions: This study provides insights on wound closure techniques and postoperative SSI made available through granular, operative data that are not found in large database analyses. Surgical wound closure technique was not associated with postoperative SSI after LEB surgery, even among patients at increased risk of infection. These data support individualization of wound closure techniques among patients undergoing LEB surgery., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: The management of vascular trauma requires specialized training and expertise. Although traumatic vascular injury is treated currently by both vascular and trauma surgeons in modern practice, it remains unclear who will inherit the role of managing vascular trauma in the coming decades. In this study, we examined disparities in operative experience in vascular trauma among surgical trainees across different surgical specialties., Methods: Accreditation Council for Graduate Medical Education national operative log reports were collected for graduating vascular surgery residents (VSRs), vascular surgery fellows (VSFs), and general surgery residents (GSRs) from 2012 to 2022. Total operative volume for traumatic vascular injury was examined, as were the five major contributing operative domains (neck, thoracic, abdominal, peripheral, and fasciotomy)., Results: A total of 22,052 GSRs, 334 VSRs, and 1672 VSFs graduated over the 10-year study period. VSR had the highest vascular trauma case volume (24.9 ± 3.9 cases/5 years), followed by VSF (22.1 ± 1.5 cases/2 years) then GSR (2.4 ± 0.3 cases/5 years; P < .001). Thoracic vessel exploration/repair (0.7 cases vs 0.6 cases vs 0.0 cases), abdominal vessel exploration/repair (1.0 cases vs 0.9 cases vs 0.0 cases), neck vessel exploration/repair (4.0 cases vs 3.4 cases vs 0.2 cases), peripheral vessel exploration/repair (12.1 cases vs 9.5 cases vs 1.1 cases), and lower extremity fasciotomy for trauma (7.2 cases vs 7.6 cases vs 1.1 cases) were most frequent among the VSR and VSF groups (P < .001 each). On linear regression analysis, both VSF (+0.5 cases/y; R 2  = 0.81; P < .001) and GSR (+0.1 cases/y; R 2  = 0.75; P = .001) groups experienced a growth in vascular trauma volume. Contrariwise, vascular trauma volume did not change among graduating VSRs (R 2  = 0.13; P = .31)., Conclusions: Dedicated vascular surgical training provides the highest operative exposure to civilian vascular trauma in the United States., Competing Interests: Disclosures None., (Copyright © 2024.

Objective: Decision-making regarding level of lower extremity amputation is sometimes challenging. Selecting an appropriate anatomic level for major amputation requires consideration of tradeoffs between postoperative function and risk of wound complications that may require additional operations, including debridement and/or conversion to above-knee amputation (AKA). We evaluated the utility of common, non-invasive diagnostic tests used in clinical practice to predict the need for reoperations among patients undergoing primary, elective, below knee-amputations (BKAs) by vascular surgeons., Methods: Patients undergoing elective BKA over a 5-year period were identified using Current Procedural Terminology codes. Medical records were reviewed to characterize demographics, pre-amputation testing transcutaneous oxygen tension (TcPO 2 ), and ankle-brachial index (ABI). The need for ipsilateral post-BKA reoperation (including BKA revision and/or conversion to AKA) regardless of indication was the primary outcome. Associations were evaluated using univariable and multivariable logistic regression models. Cutpoints for TcPO 2 values associated with amputation reoperation were evaluated using receiver operating characteristic curves., Results: We identified 175 BKAs, of which 46 (26.3%) required ipsilateral reoperation (18.9% BKA revisions and 14.3% conversions to AKA). The mean age was 63.3 ± 14.8 years. Most patients were male (65.1%) and White (72.0%). Mean pre-amputation calf TcPO 2 was 40.0 ± 20.5 mmHg, and mean ABI was 0.64 ± 0.45. In univariable models, post-BKA reoperation was associated with calf TcPO 2 (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.94-0.99; P = .013) but not ABI (OR, 0.53; 95% CI, 0.19-1.46; P = .217). Univariable associations with reoperation were also identified for age (OR, 0.97; 95% CI, 0.94-0.990; P = .003) and diabetes (OR, 0.43; 95% CI, 0.21-0.87; P = .019). No associations with amputation revision were identified for gender, race, end-stage renal disease, or preoperative antibiotics. Calf TcPO 2 remained associated with post-BKA reoperation in a multivariable model (OR, 0.97; 95% CI, 0.94-0.99; P = .022) adjusted for age (OR, 0.98; 95% CI, 0.94-1.01; P = .222) and diabetes (OR, 0.98; 95% CI, 0.94-1.01; P = .559). Receiver operating characteristic analysis suggested a TcPO 2 ≥38 mmHg as an appropriate cut-point for assessing risk for BKA revision (area under the curve = 0.682; negative predictive value, 0.91)., Conclusions: Reoperation after BKA is common, and reoperation risk was associated with pre-amputation TcPO 2 . For patients undergoing elective BKA, higher risk of reoperation should be discussed with patients with an ipsilateral TcPO 2  <38 mmHg., Competing Interests: Disclosures None., (Copyright © 2024 Society for Vascular Surgery.

Background: An enriching learning environment is integral to resident wellness and education. Integrated vascular (VS) and general surgery (GS) residents share 18 months of core GS rotations during the postgraduate years 1-3 (PGY1-3); differences in their experiences may help identify practical levers for change., Methods: We used a convergent mixed-methods design. Cross-sectional surveys were administered after the 2020 American Board of Surgery In-Training Examination and Vascular Surgery In-Training Examination, assessing eight domains of the learning environment and resident wellness. Multivariable logistic regression models identified factors associated with thoughts of attrition between categorical PGY1-3 residents at 57 institutions with both GS and VS programs. Resident focus groups were conducted during the 2022 Vascular Annual Meeting to elicit more granular details about the experience of the learning environment. Transcripts were analyzed using inductive and deductive logics until thematic saturation was achieved., Results: Surveys were completed by 205 VS and 1198 GS PGY1-3 residents (response rates 76.8% for VS and 82.5% for GS). After adjusting for resident demographics, PGY level, and program type, GS residents were more likely than their VS peers to consider leaving their programs (odds ratio [OR]: 2.61, 95% confidence interval [CI]: 1.37-4.99). This finding did not persist after adjusting for differences in perceptions of the learning environment, specifically: GS residents had higher odds of mistreatment (OR: 1.99, 95% CI: 1.36-2.90), poorer work-life integration (OR: 2.88, 95% CI: 1.41-5.87), less resident camaraderie (OR: 3.51, 95% CI: 2.26-5.45), and decreased meaning in work (OR: 2.94, 95% CI: 1.80-4.83). Qualitative data provided insight into how the shared learning environment was perceived differently: (1) vascular trainees expressed that early specialization and a smaller, more invested faculty allow for an apprenticeship model with early operative exposure, hands-on guidance, frequent feedback, and thus early skill acquisition (meaning in work); (2) a smaller program is conducive to closer relationships with co-residents and faculty, increasing familiarity (camaraderie and work-life integration); and (3) due to increased familiarity with program leadership, vascular trainees feel more comfortable reporting mistreatment, allowing for prompt responses (mistreatment)., Conclusions: Despite sharing a learning environment, VS and GS residents experience training differently, contributing to differential thoughts of attrition. These differences may be attributable to intrinsic features of the integrated training paradigm that are not easily replicated by GS programs, such as smaller program size and higher faculty investment due to early specialization. Alternative strategies to compensate for these inherent differences should be considered (eg, structured operative entrustment programs and faculty incentivization)., Competing Interests: Disclosures None., (Copyright © 2023 Society for Vascular Surgery.

Background: Work-related pain is a known risk factor for vascular surgeon burnout. It risks early attrition from our workforce and is a recognized threat to the specialty. Our study aimed to understand whether work-related pain similarly contributed to vascular surgery trainee well-being., Methods: A confidential, voluntary survey was administered after the 2022 Vascular Surgery In-Service Examination to trainees in all Accreditation Council for Graduate Medical Education-accredited vascular surgery programs. Burnout was measured by a modified, abbreviated Maslach Burnout Inventory; pain after a full day of work was measured using a 10-point Likert scale and then dichotomized as "no to mild pain" (0-2) vs "moderate to severe pain" (3-9). Univariable analyses and multivariable regression assessed associations of pain with well-being indicators (eg, burnout, thoughts of attrition, and thoughts of career change). Pain management strategies were included as additional covariables in our study., Results: We included 527 trainees who completed the survey (82.2% response rate); 38% reported moderate to severe pain after a full day of work, of whom 73.6% reported using ergonomic adjustments and 67.0% used over-the-counter medications. Significantly more women reported moderate to severe pain than men (44.3% vs 34.5%; P < .01). After adjusting for gender, training level, race/ethnicity, mistreatment, and dissatisfaction with operative autonomy, moderate-to-severe pain (odds ratio, 2.52; 95% confidence interval, 1.48-4.26) and using physiotherapy as pain management (odds ratio, 3.06; 95% confidence interval, 1.02-9.14) were risk factors for burnout. Moderate to severe pain was not a risk factor for thoughts of attrition or career change after adjustment., Conclusions: Physical pain is prevalent among vascular surgery trainees and represents a risk factor for trainee burnout. Programs should consider mitigating this occupational hazard by offering ergonomic education and adjuncts, such as posture awareness and microbreaks during surgery, early and throughout training., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Objective: Visceral branch artery dissection (VBAD) is uncommon and may occur with or without an associated aortic dissection (AD). We hypothesized that isolated VBAD would have a more benign clinical course than those with concurrent AD and compared survival outcomes stratified based on aortic involvement., Methods: VBAD over a 5-year period were identified using International Classification of Diseases codes. Data related to patient demographics, comorbid conditions, clinical presentation, management (including procedural interventions), and survival were obtained from medical records. Anatomic imaging studies were reviewed to characterize anatomy, including the presence or absence of concurrent AD. Overall survival and intervention-free survival were evaluated using Kaplan-Meier and Cox proportional hazards models., Results: A total of 299 VBAD were identified, 174 of which were isolated VBAD and 125 were associated with concurrent AD. Seventy-one percent of patients were men, 77% were White, and 85% were non-Hispanic. The mean age was 61.1 ± 14.4 years. The mean follow-up was 53.2 ± 50.0 months. The estimated overall survival was 88.2% and the estimated overall intervention-free survival was 55.6% at 12 months. Isolated VBAD had better overall survival than those with concurrent AD (69.2% vs 32.4%; P < .001). Concurrent AD was also associated with inferior intervention-free survival (57.5% vs 7.3%; P < .001). Acute presentation was associated with decreased intervention-free survival (86.1% vs 13.4%; P < .001). Acute presentation was also associated with decreased overall survival in patients with isolated VBAD (60.8% vs 80.0% at 180 months; P < .001) and inferior intervention-free survival (48.4% vs 69.5% at 180 months; P < .001) in the subgroup of patients with isolated VBAD. Multivariable Cox models identified that age (hazard ratio [HR]: 1.05, standard deviation [SD]: 0.02; P = .001) was associated with inferior survival and renal dissections (HR: 3.08, SD: 0.99; P = .001) or mesenteric and renal dissections (HR: 3.39, SD: 1.44; P = .004) were associated with inferior intervention-free survival., Conclusions: Isolated VBAD has superior overall and intervention-free survival to those associated with concurrent AD. The absence vs presence of aortic involvement is useful for risk stratification and may support tailored approaches to the frequency of imaging surveillance., Competing Interests: Disclosures None., (Copyright © 2023 Society for Vascular Surgery.

Background: Comprehensive vascular care includes both arterial and venous disease management. However, operative training in venous disease is often significantly overshadowed by arterial procedures, despite the public health burden of acute and chronic venous disease. The purpose of this study is to evaluate the case-mix and volume of venous procedures performed by graduating integrated vascular surgery residents and fellows in the United States., Methods: Accreditation Council for Graduate Medical Education national operative log reports were compiled for graduating integrated VSR (vascular surgery residency) and traditional vascular surgery fellowship (VSF) trainees from academic years 2013 to 2022. Only cases categorized as "surgeon fellow", "surgeon chief", or "surgeon junior" were included. Linear regression analysis was utilized to evaluate trends in case-mix and volume., Results: Over the 10-year study period, total vascular cases increased for both VSR (mean 870.5 ± 9.3 cases, annual change +9.5 cases/year, R 2  = 0.77, P < 0.001) and VSF (mean 682.1 ± 6.9 cases, annual change +6.7 cases/year, R 2  = 0.85, P < 0.001) trainees. Concurrently, the proportion of venous cases in the VSR group decreased from 12.5% to 7.3% (annual change -3.7 cases/year, R 2  = 0.72, P < 0.001). VSR trainees experienced an annual decrease in 4 of the top 5 venous case types performed, including venous angioplasty/stenting (-1.6 cases/year, P = 0.002), vena cava filter placement (-0.9 cases/year, P = 0.002), endoluminal ablation (-0.2 cases/year, P = 0.47), diagnostic venography (-1.7 cases/year, P < 0.001), and varicose vein treatment (-1.0 cases/year, P < 0.001). Venous cases proportions also decreased in the VSF group from 8.4% to 6.2% (annual change -2.2 cases/year, R 2  = 0.54, P = 0.002). VSF trainees experienced an annual decrease in 4 of the top 5 venous case types, including venous angioplasty/stenting (-1.5 cases/year, P = 0.003), diagnostic venography (-1.2 cases/year, P < 0.001), vena cava filter placement (-0.2 cases/year, P = 0.44), endoluminal ablation (-0.6 cases/year, P < 0.001), and varicose vein treatment (-0.1 cases/year, P = 0.04). Both VSR and VSF trainee groups graduated with fewer than 5 cases for each of the following venous procedures-percutaneous mechanical thrombectomy, venous thrombolysis, open venous reconstruction, sclerotherapy, venous embolectomy, portal-systemic shunting, venous ulceration treatment, and arteriovenous malformation treatment., Conclusions: Current vascular residents and fellows have limited exposure to venous procedures, in part due to a proportional decline in venous cases. More robust venous operative experience is needed during surgical training. Further studies are needed to understand whether this discrepancy in venous and arterial training impacts career progression and patient outcomes., (Copyright © 2023 Elsevier Inc.

Background: Endovascular and hybrid interventions have played an increasingly prominent role in the treatment of peripheral arterial disease (PAD) in the past decade. This shift has prompted concerns about the adequacy of open surgical training for current surgical residents. Moreover, the recent Best Surgical Therapy in Patients With Critical Limb Ischemia trial has further emphasized the importance of open surgical techniques in the treatment of peripheral arterial disease. The purpose of this study was to examine national temporal trends in peripheral operative volume among integrated vascular surgery residents., Methods: Data was obtained from the Accreditation Council for Graduate Medical Education national data reports for integrated vascular surgery residents. Case volumes for surgeon chief or surgeon junior cases were collected from academic years 2012 to 2013 and 2021 to 2022. Trends in case-mix and volume were evaluated using linear regression analysis., Results: The mean total vascular operative volume increased from 851.2 to 914.3 cases among graduating chief residents, with an annual growth of 8.5 ± 1.7 cases/year (R 2  = 0.77; P < .0001). Major vascular case volume also increased at a rate of 5.7 ± 1.2 cases/year (R 2  = 0.74; P < .001). Among operative categories, peripheral cases were the most frequent (n = 232.2 [26.6%]) and demonstrated the greatest annual growth (+8.0 ± 0.8 cases/year, R 2  = 0.93; P < .001). No changes were seen in volume of open peripheral cases, including suprainguinal bypass (+0.1 ± 0.2 cases/year; R 2  = 0.08; P = .40) or femoropopliteal bypass procedures (-0.1 ± 0.2 cases/year; R 2  = 0.17; P = .20). Infrapopliteal bypass (+0.4 ± 0.1 cases/year; R 2  = 0.48; P = .006), iliac/femoral endarterectomy (+1.3 ± 0.2 cases/year; R 2  = 0.82; P < .001), and leg thromboembolectomy (+0.4 ± 0.1 cases/year; R 2  = 0.64; P < .001) all demonstrated annual growth. For endovascular peripheral cases, aortoiliac revascularization (+3.4 ± 0.3 cases/year; R 2  = 0.94; P < .001), femoropopliteal revascularization (+5.4 ± 0.2 cases/year; R 2  = 0.98; P < .001), and tibioperoneal revascularization (+2.0 ± 0.2 cases/year; R 2  = 0.92; P < .001) all increased in volume. Lower extremity amputations, including above-knee amputation (+0.6 ± 0.2 cases/year; R 2  = 0.65; P < .001) and below-knee amputation (+0.9 ± 0.2 cases/year; R 2  = 0.72; P < .001) also demonstrated an increase in volume., Conclusions: Current graduating residents have higher open and endovascular case volumes for peripheral artery disease on a national level, despite the increasing popularity of endovascular techniques. Further studies are needed to identify how these trends may impact current vascular surgery milestones. These trends may also influence the rising interest in competency-based training programs., Competing Interests: Disclosures None., (Copyright © 2023 Society for Vascular Surgery.

Abdominal aortic aneurysm (AAA) is a common disease with substantial heritability. In this study, we performed a genome-wide association meta-analysis from 14 discovery cohorts and uncovered 141 independent associations, including 97 previously unreported loci. A polygenic risk score derived from meta-analysis explained AAA risk beyond clinical risk factors. Genes at AAA risk loci indicate involvement of lipid metabolism, vascular development and remodeling, extracellular matrix dysregulation and inflammation as key mechanisms in AAA pathogenesis. These genes also indicate overlap between the development of AAA and other monogenic aortopathies, particularly via transforming growth factor β signaling. Motivated by the strong evidence for the role of lipid metabolism in AAA, we used Mendelian randomization to establish the central role of nonhigh-density lipoprotein cholesterol in AAA and identified the opportunity for repurposing of proprotein convertase, subtilisin/kexin-type 9 (PCSK9) inhibitors. This was supported by a study demonstrating that PCSK9 loss of function prevented the development of AAA in a preclinical mouse model., (© 2023.

Background: Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch., Methods: Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions., Results: 288 patients with ASA with or without KD were identified; 222 left-sided aortic arch (LAA), and 66 right-sided aortic arch (RAA). Mean age at repair was younger in LAA 54 vs. 58 years (P = 0.06). Patients in RAA were more likely to undergo repair due to symptoms (72.7% vs. 55.9%, P = 0.01), and more likely to present with dysphagia (57.6% vs. 39.1%, P < 0.01). The hybrid open/endovascular approach was the most common repair type in both groups. Rates of intraoperative complications, death within 30 days, return to the operating room, symptom relief and endoleaks were not significantly different. For patients with symptom status follow-up data, in LAA, 61.7% had complete relief, 34.0% had partial relief and 4.3% had no change. In RAA, 60.7% had complete relief, 34.4% had partial relief and 4.9% had no change., Conclusions: In patients with ASA/KD, RAA patients were less common than LAA, presented more frequently with dysphagia, had symptoms as an indication for intervention, and underwent treatment at a younger age. Open, endovascular and hybrid repair approaches appear equally effective, regardless of arch laterality., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

Objective: As medical education systems increasingly move toward competency-based training, it is important to understand the tools available to assess competency and how these tools are utilized. The Society for Improving Medical Professional Learning (SIMPL) offers a smart phone-based assessment system that supports workplace-based assessment of residents' and fellows' operative autonomy, performance, and case complexity. The purpose of this study was to characterize implementation of the SIMPL app within vascular surgery integrated residency (0+5) and fellowship (5+2) training programs., Methods: SIMPL operative ratings recorded between 2018 and 2022 were collected from all participating vascular surgery training institutions (n = 9 institutions with 5+2 and 0+5 programs; n = 4 institutions with 5+2 program only). The characteristics of programs, trainees, faculty, and SIMPL operative assessments were evaluated using descriptive statistics., Results: Operative assessments were completed for 2457 cases by 85 attendings and 86 trainees, totaling 4615 unique operative assessment ratings. Attendings included dictated feedback in 52% of assessments. Senior-level residents received more assessments than junior-level residents (postgraduate year [PGY]1-3, n = 439; PGY4-5, n = 551). Performance ratings demonstrated increases from junior to senior trainees for both resident and fellow cohorts with "performance-ready" or "exceptional performance" ratings increasing by nearly two-fold for PGY1 to PGY5 residents (28.1% vs 40.6%), and from first- to second-year fellows (PGY6, 46.7%; PGY7, 60.3%). Similar gains in autonomy were demonstrated as trainees progressed through training. Senior residents were more frequently granted autonomy with "supervision only" than junior residents (PGY1, 8.7%; PGY5, 21.6%). "Supervision only" autonomy ratings were granted to 21.8% of graduating fellows. Assessment data included a greater proportion of complex cases for senior compared with junior fellows (PGY6, 20.9% vs PGY7, 26.5%). Program Directors felt that faculty and trainee buy-in were the main barriers to implementation of the SIMPL assessment app., Conclusions: This is the first description of the SIMPL app as an operative assessment tool within vascular surgery that has been successfully implemented in both residency and fellowship programs. The assessment data demonstrates expected progressive gains in trainees' autonomy and performance, as well as increasing case complexity, across PGY years. Given the selection of SIMPL as the assessment platform for required American Board of Surgery and Vascular Surgery Board Entrustable Professional Activities assessments, understanding facilitators and barriers to implementation of workplace-based assessments using this app is imperative, particularly as we move toward competency-based medical education., (Copyright © 2023 Society for Vascular Surgery.

Objective: Patients with venous insufficiency can be treated with ablation or phlebectomy, or both. Patients undergoing superficial venous procedures have an elevated risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). At our institution, we initiated a standardized protocol in which patients with a Caprini score (2005 version) of ≥8 are treated with 1 week of prophylactic anticoagulation after the procedure. Duplex ultrasound was performed at 1 week and then within 90 days after the procedure. This aim of the present study was to determine the thrombotic and clinical outcomes after superficial vein procedures using a standardized protocol for DVT/PE risk assessment and prophylaxis., Methods: We performed a retrospective analysis of prospectively collected data of superficial vein procedures from 2015 to 2021 at a single center. The patient demographics, CEAP (Clinical-Etiology-Anatomy-Pathophysiology) clinical class, venous clinical severity score, patient-reported outcomes, treatment type, Caprini scores, pre- and postoperative anticoagulation use, and outcomes were collected. Descriptive statistics were used for the patient demographics, procedure details, and unadjusted surgical outcomes. Multivariable logistic regression was used to evaluate the relationship between procedure type and DVT and PE after adjusting for patient characteristics, disease severity, periprocedural anticoagulation, and Caprini score., Results: A total of 1738 limbs were treated with ablation (n = 820), phlebectomy (n = 181), or ablation and phlebectomy (n = 737). More patients were women (67.1%) and White (90.9%). The overall incidence of DVT/PE was 1.4%. Patients undergoing ablation with phlebectomy had higher rates of DVT/PE (2.7%) than those undergoing ablation (0.2%) or phlebectomy alone (1.7%; P < .01). However, only 30% of DVTs were above the knee. On multivariate analysis, only the procedure type predicted for DVT/PE. However, patients undergoing ablation and phlebectomy achieved better patient-reported outcomes (Caprini score, 5.9) compared with those undergoing ablation (Caprini score, 7.2) or phlebectomy (Caprini score, 7.9) alone (P < .01). The best improvement in the venous clinical severity score was seen with phlebectomy alone., Conclusions: The expected difference in the DVT/PE rates between high- and low-risk groups did not materialize in our patients, perhaps secondary to the additional chemoprophylaxis prescribed for the high-risk cohort (Caprini score, ≥8). These results call for a randomized trial to assess the efficacy of a standardized protocol in the reduction of DVT/PE after superficial vein procedures., (Copyright © 2023 Society for Vascular Surgery.

Objective: Mistreatment among vascular surgery trainees is a known risk factor for physician burnout. This study aims to characterize forms of and identify sources of mistreatment., Methods: This is a cross-sectional study of United States vascular surgery trainees who voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between genders. Logistic regression was used for multivariable analysis., Results: Representing all 125 vascular surgery training programs, 510 trainees (66.9% male) participated in the survey (83.6% response rate). Mistreatment was reported by 54.8% of trainees, with twice as many women reporting as men (82.3% vs 41.0%; P < .001). Women reported higher rates of being shouted at (44.1% vs 21.1%; P < .001); repeatedly reminded of errors (24.3% vs 16.1%; P = .04); ignored/treated hostilely (28.9% vs 10.5%; P < .001); subjected to crude/sexually demeaning remarks, stories, jokes (19.2% vs 2.1%; P < .001); evaluated by different standards (29.3% vs 2.1%; P < .001); and mistaken for a non-physician (75.2% vs 3.5%; P < .001). Among trainees reporting bullying, attendings were the most common source (68.5%). Patients and their families were the most common source of sexual harassment (66.7%), gender discrimination (90.4%), and racial discrimination (74.4%). Compared with men, women identified more patients and families as the source of bullying (50.0% vs 29.7%; P = .005), gender discrimination (97.2% vs 50.0%; P < .001), and sexual harassment (78.4% vs 27.3%; P = .003). Compared with men, women more frequently felt unprepared to respond to the behavior in the moment (10.4% vs 4.6%; P = .002), did not know how to report mistreatment at their institution (7.6% vs 3.2%; P = .04), and did not believe that their institution would take their mistreatment report seriously (9.0% vs 3.9%; P = .002). On multivariable analysis, female gender was an independent risk factor for both gender discrimination (odds ratio, 56.62; 95% confidence interval, 27.89-115) and sexual harassment (odds ratio, 26.2; 95% confidence interval, 3.34-14.8) when adjusting for children, training year, relationship status, and training program location., Conclusions: A majority of vascular surgery trainees experience mistreatment during training. Sources and forms of abuse are varied. Understanding the sources of mistreatment is critical to guide intervention strategies such as faculty remediation and/or sanctions; allyship training for staff, residents, and faculty; and institutional procedures for patient-initiated abuse., (Copyright © 2023 Society for Vascular Surgery.

Renovascular hypertension (RVH) is a secondary form of high blood pressure resulting from impaired blood flow to the kidneys with subsequent activation of the renin-angiotensin-aldosterone system. Often, this occurs due to abnormally small, narrowed, or blocked blood vessels supplying one or both kidneys (ie: renal artery occlusive disease) and is correctable. Juxtaglomerular cells release renin in response to decreased pressure, which in turn catalyzes the cleavage of circulating angiotensinogen synthesized by the liver to the decapeptide angiotensin I. Angiotensin-converting enzyme then cleaves angiotensin I to form the octapeptide angiotensin II, a potent vasopressor and the primary effector of renin-induced hypertension. The effects of angiotensin II are mediated by signaling downstream of its receptors. Angiotensin receptor type 1 is a G-protein-coupled receptor that activates vasoconstrictor and mitogenic signaling pathways resulting in peripheral arteriolar vasoconstriction and increased renal tubular reabsorption of sodium and water which promotes intravascular volume expansion. Angiotensin II stimulates the adrenal cortical release of aldosterone, which promotes renal tubular sodium reabsorption, resulting in volume expansion. Angiotensin II acts on glial cells and regions of the brain responsible for blood pressure regulation increasing renal sympathetic activation. Angiotensin II simulates the release of vasopressin from the pituitary which stimulates thirst and water reabsorption from the kidney to expand the intravascular volume and cause peripheral vasoconstriction (increased sympathetic tone). All of these mechanisms coalesce to increase arterial pressure by way of arteriolar constriction, enhanced cardiac output, and the retention of sodium and water., (Copyright © 2023 Elsevier Inc.

Objective: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset., Methods: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders. We report the early and mid-term clinical outcomes including stroke and mortality, technical success, and other operative outcomes including reintervention rates, patency, and endoleak., Results: Overall, 285 patients were identified during the study period. The mean patient age was 57 years; 47% were female and 68% presented with symptoms. A right-sided arch was present in 23%. The mean KD diameter was 47.4 mm (range, 13.0-108.0 mm). The most common indication for treatment was symptoms (59%), followed by aneurysm size (38%). The most common symptom reported was dysphagia (44%). A ruptured KD was treated in 4.2% of cases, with a mean diameter of 43.9 mm (range, 18.0-100.0 mm). An open procedure was performed in 101 cases (36%); the most common approach was ASA ligation with subclavian transposition. An endovascular or hybrid approach was performed in 184 patients (64%); the most common approach was thoracic endograft and carotid-subclavian bypass. A staged operative strategy was employed more often than single setting repair (55% vs 45%). Compared with endovascular or hybrid approach, those in the open procedure group were more likely to be younger (49 years vs 61 years; P < .0001), female (64% vs 36%; P < .0001), and symptomatic (85% vs 59%; P < .0001). Complete or partial symptomatic relief at 1 year after intervention was 82.6%. There was no association between modality of treatment and symptom relief (open 87.2% vs endovascular or hybrid approach 78.9%; P = .13). After the intervention, 11 subclavian occlusions (4.5%) occurred; 3 were successfully thrombectomized resulting in a primary and secondary patency of 95% and 96%, respectively, at a median follow-up of 39 months. Among the 33 reinterventions (12%), the majority were performed for endoleak (36%), and more reinterventions occurred in the endovascular or hybrid approach than open procedure group (15% vs 6%; P = .02). The overall survival rate was 87.3% at a median follow-up of 41 months. The 30-day stroke and death rates were 4.2% and 4.9%, respectively. Urgent or emergent presentation was independently associated with increased risk of 30-day mortality (odds ratio [OR], 19.8; 95% confidence interval [CI], 3.3-116.6), overall mortality (OR, 3.6; 95% CI, 1.2-11.2) and intraoperative complications (OR, 8.3; 95% CI, 2.8-25.1). Females had a higher risk of reintervention (OR, 2.6; 95% CI, 1.0-6.5). At an aneurysm size of 44.4 mm, receiver operator characteristic curve analysis suggested that 60% of patients would have symptoms., Conclusions: Treatment of ASA/KD can be performed safely with low rates of mortality, stroke and reintervention and high rates of symptomatic relief, regardless of the repair strategy. Symptomatic and urgent operations were associated with worse outcomes in general, and female gender was associated with a higher likelihood of reintervention. Given the worse overall outcomes when symptomatic and the inherent risk of rupture, consideration of repair at 40 mm is reasonable in most patients. ASA/KD can be repaired in asymptomatic patients with excellent outcomes and young healthy patients may be considered better candidates for open approaches versus endovascular or hybrid modalities, given the lower likelihood of reintervention and lower early mortality rate., (Copyright © 2023 Society for Vascular Surgery.

Objective: Racial/ethnic discrimination is one form of mistreatment and a known risk factor for physician burnout. In the present study, we aimed to characterize the forms and identify the sources of racial/ethnic discrimination among vascular surgery trainees., Methods: We performed a cross-sectional study of U.S. vascular surgery trainees who had voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between race and ethnicity groups. We used χ 2 tests and logistic regression for bivariate and multivariable analyses, respectively., Results: Representing all 123 vascular surgery training programs, 510 trainees (66.9% men) participated in the survey (83.6% response rate). Most of the trainees had self-identified as White (53.1%), followed by Asian (24.4%), Hispanic/Latinx (7.6%), Black (4.2%), and other/prefer not to say (10.8%). No significant differences were found in the self-reported duty hour violations among the groups. Black (56.3%) and Asian (36.3%) trainees reported higher rates of racial/ethnic discrimination compared with the White, Hispanic/Latinx, and other/prefer not to say groups (P < .001). Patients and their families were reported as the most common source (74.7%). Other reported sources of discrimination included nurses or staff (60%), attendings (37.4%), co-residents (31.3%), and administration (16.9%). Regarding specific forms of racial discrimination, Black and Asian trainees reported the highest rates of different standards of evaluation (20% and 5.9%, respectively), being mistaken for a nonphysician (50.0% and 5.9%, respectively), slurs and/or hurtful comments (13.3% and 5.9%, respectively), social isolation (13.0% and 1.0%, respectively), and being mistaken for another trainee of the same race/ethnicity (60.0% and 33.7%, respectively). Only 62.5% of Black trainees reported their program/institution would take their mistreatment report seriously compared with the White (88.9%), Hispanic/Latinx (88.2%), Asian (83.2%), and other/prefer not to say (71.4%) trainees (P = .01). On multivariable analysis, female gender (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.44-4.33), Asian race (OR, 6.9; 95% CI, 3.53-13.3), Black race (OR, 13.6; 95% CI, 4.25-43.4), and training in the Southeastern United States (OR, 3.8; 95% CI, 1.17-12.80) were risk factors for racial/ethnic discrimination., Conclusions: The results from the survey revealed that racial/ethnic discrimination persists in surgical training programs, with Asian and Black trainees reporting higher rates than other racial and ethnic groups. Overall, patients and family members were the most common source of racial/ethnic discrimination. However, faculty, staff, and co-trainees also contributed to racial/ethnic discrimination. Further interventions that optimize diversity, equity, and inclusion strategies and policies to address all forms of racial/ethnic discrimination with faculty, staff, and patients within the hospital are critically needed., (Published by Elsevier Inc.)

Background: The risk of arterial diseases may be elevated among family members of individuals having multifocal fibromuscular dysplasia (FMD). We sought to investigate the risk of arterial diseases in families of individuals with FMD., Methods: Family histories for 73 probands with FMD were obtained, which included an analysis of 463 total first-degree relatives focusing on FMD and related arterial disorders. A polygenic risk score for FMD (PRS FMD ) was constructed from prior genome-wide association findings of 584 FMD cases and 7139 controls and evaluated for association with an abdominal aortic aneurysm (AAA) in a cohort of 9693 AAA cases and 294 049 controls. A previously published PRS AAA was also assessed among the FMD cases and controls., Results: Of all first degree relatives of probands, 9.3% were diagnosed with FMD, aneurysms, and dissections. Aneurysmal disease occurred in 60.5% of affected relatives and 5.6% of all relatives. Among 227 female first-degree relatives of probands, 4.8% (11) had FMD, representing a relative risk (RR) FMD of 1.5 ([95% CI, 0.75-2.8]; P =0.19) compared with the estimated population prevalence of 3.3%, though not of statistical significance. Of all fathers of FMD probands, 11% had AAAs resulting in a RR AAA of 2.3 ([95% CI, 1.12-4.6]; P =0.014) compared with population estimates. The PRS FMD was found to be associated with an AAA (odds ratio, 1.03 [95% CI, 1.01-1.05]; P =2.6×10 -3 ), and the PRS AAA was found to be associated with FMD (odds ratio, 1.53 [95% CI, 1.2-1.9]; P =9.0×10 -5 ) as well., Conclusions: FMD and AAAs seem to be sex-dimorphic manifestations of a heritable arterial disease with a partially shared complex genetic architecture. Excess risk of having an AAA according to a family history of FMD may justify screening in family members of individuals having FMD.

Academic medicine as a practice model provides unique benefits to society. Clinical care remains an important part of the academic mission; however, equally important are the educational and research missions. More specifically, the sustainability of health care in the United States relies on an educated and expertly trained physician workforce directly provided by academic medicine models. Similarly, the research charge to deliver innovation and discovery to improve health care and to cure disease is key to academic missions. Therefore, to support and promote the growth and sustainability of academic medicine, attracting and engaging top talent from fellows in training and early career faculty is of vital importance. However, as the health care needs of the nation have risen, clinicians have experienced unprecedented demand, and individual wellness and burnout have been examined more closely. Here, we provide a close look at the unique drivers of burnout in academic cardiovascular medicine and propose system-level and personal interventions to support individual wellness in this model.

Objective: The optimal revascularization modality following complete resection of aortic graft infection (AGI) without enteric involvement remains unclear. The purpose of this investigation is to determine the revascularization approach associated with the lowest morbidity and mortality using real-world data in patients undergoing complete excision of AGI., Methods: A retrospective, multi-institutional study of AGI from 2002 to 2014 was performed using a standardized database. Baseline demographics, comorbidities, and perioperative variables were recorded. The primary outcome was infection-free survival. Descriptive statistics, Kaplan-Meier survival analysis, and univariate and multivariable analyses were performed., Results: A total of 241 patients at 34 institutions from seven countries presented with AGI during the study period (median age, 68 years; 75% male). The initial aortic procedures that resulted in AGI were 172 surgical grafts (71%), 66 endografts (27%), and three unknown (2%). Of the patients, 172 (71%) underwent complete excision of infected aortic graft material followed by in situ (in-line) bypass (ISB), including antibiotic-treated prosthetic graft (35%), autogenous femoral vein (neo-aortoiliac surgery) (24%), and cryopreserved allograft (41%). Sixty-nine patients (29%) underwent extra-anatomic bypass (EAB). Overall median Kaplan-Meier estimated survival was 5.8 years. Perioperative mortality was 16%. When stratified by ISB vs EAB, there was a significant difference in Kaplan-Meier estimated infection-free survival (2910 days; interquartile range, 391-3771 days vs 180 days; interquartile range, 27-3750 days; P < .001). There were otherwise no significant differences in presentation, comorbidities, or perioperative variables. Multivariable Cox regression showed lower infection-free survival among patients with EAB (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.6-3.6; P < .001), polymicrobial infection (HR, 2.2; 95% CI, 1.4-3.5; P = .001), methicillin-resistant Staphylococcus aureus infection (HR, 1.7; 95% CI, 1.1-2.7; P = .02), as well as the protective effect of omental/muscle flap coverage (HR, 0.59; 95% CI, 0.37-0.92; P = .02)., Conclusions: After complete resection of AGI, perioperative mortality is 16% and median overall survival is 5.8 years. EAB is associated with nearly a two and one-half-fold higher reinfection/mortality compared with ISB. Omental and/or muscle flap coverage of the repair appear protective., (Copyright © 2022 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Objectives: Abdominal aortic coarctation and hypoplasia are uncommon diseases, recognized most often in pediatric-aged individuals. Comprehensive studies regarding the pathologic spectrum of these aortopathies are nonexistent. This investigation was undertaken to better define the histologic and morphologic character of abdominal aortic narrowings affecting children and assess its potential relevance to contemporary clinical practice., Methods: Aortic specimens obtained during open operations in children being treated for symptomatic, noninflammatory abdominal aortic narrowings at the University of Michigan were subjected to histologic study after hematoxylin and eosin, Movat, Verhoeff Van Gieson, and Masson's trichrome preparations. Microscopic findings were correlated with the anatomic aortic images. In addition, a detailed review was completed of all prior reports in the English literature that included images depicting the histologic character of noninflammatory abdominal aortic narrowings in children., Results: Among a series of 67 pediatric-aged individuals undergoing open surgical interventions for abdominal aortic narrowings, eight children ranging in age from 9 months to 18 years, had adequate aortic tissue available for study. The loci of the specimens paralleled the anatomic sites of segmental coarctations observed in the entire series, with involvement of the suprarenal abdominal aorta (n = 3), intrarenal aorta (n = 2), and infrarenal aorta (n = 1). Diffusely hypoplastic abdominal aortas (n = 2) included one case of a de facto aortic duplication, represented by a channel that paralleled the narrow native aorta and gave origin to celiac artery branches, as well as the superior mesenteric and renal arteries. Concentric or eccentric intimal fibroplasia was observed in every aorta, often with internal elastic fragmentation and duplication (n = 4). Media abnormalities included elastic tissue disorganization (n = 3) and focal medial fibrosis (n = 1). Organizing luminal thrombus occurred in two infants. Coexistent ostial stenoses of the celiac, superior mesenteric, or renal arteries were observed in all but the only child who had an infrarenal aortic coarctation. Neurofibromatosis type 1 affected one child whose histologic findings were indistinguishable from those of the other children. A review of prior published histologic images of abdominal aortic coarctation and hypoplasia affecting children from other centers revealed a total of 14 separate reports, each limited to single case photomicrographs, of which 11 exhibited intimal fibroplasia., Conclusions: Intimal fibroplasia is a common accompaniment of developmental abdominal aortic coarctation and hypoplasia. It is posited that intimal fibroplasia, which is likely progressive in instances of abnormal shear stresses in these diminutive vessels, may contribute to less salutary outcomes after endovascular and certain open reconstructions of pediatric abdominal aortic narrowings., (Copyright © 2022 Society for Vascular Surgery.

Objective: The aim of this study was to obtain novel perspectives regarding the effects that surgical training has on the well-being of trainees., Summary Background Data: Improving trainee well-being is a national concern given high rates of burnout, depression, and suicide among physicians. Supporters of surgical trainees may offer new perspectives regarding the effects of surgical training and point to strategies to optimize trainee wellness., Methods: This qualitative study employs semi-structured interviews of 32 support persons of trainees at a single tertiary care center with multiple surgical training programs. Interviews focused on perspectives related to supporting a surgical trainee. Interview transcripts underwent qualitative analysis with semantic and conceptual coding. Themes related to effects of training on trainee wellness are reported., Results: Four themes were identified: Who Can Endure the Most Hardship?-trainee attributes and programmatic factors contribute to trainees feeling the need to constantly endure the most hardship; Consequences of Hardship-constantly enduring hardships has significant negative effects on wellness; Trainees are Humans-trainees are people with basic human needs, especially the need for worth; Research Time as Refuge-dedicated research time is treated as an oasis away from clinical hardships., Conclusions: Perspectives from support persons can offer valuable insight into the wellness needs of surgical trainees. According to support persons, surgical training profoundly negatively impacts trainee wellness. Unlike during clinical training, dedicated research time is a period during which wellness can be prioritized. Programs should provide greater attention to mitigating the negative ramifications of surgical training and promoting wellness in a longitudinal fashion throughout training., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objective: Surgeons report higher burnout and suicidal ideation (SI) rates than the general population. This study sought to identify the prevalence and gender-specific risk factors for burnout and SI among men and women vascular surgeons to guide future interventions., Methods: In 2018, active Society for Vascular Surgery members were surveyed confidentially using the Maslach Burnout Index embedded in a questionnaire that captured demographic and practice-related characteristics. Results were stratified by gender. Univariate and multivariate logistic regression models were developed to identify predictors for the end points of burnout and SI., Results: Overall survey response rate was 34.3% (N = 878) of practicing vascular surgeons. A higher percentage of women responded (19%) than compose membership in the Society for Vascular Surgery (13.7%). Women respondents were significantly younger, with fewer years in practice, and were less likely to be in private practice than the men who responded. Women were also less likely to be married/partnered, or to have children. The prevalence of burnout was similar for women and men (42.3% and 40.9%; P = nonsignificant); however, the prevalence of SI was significantly higher in women (12.9% vs 6.6%; P < .007). Whereas there was no difference in mean hours worked or call taken, women were more likely to have had a recent conflict between work and home responsibilities and to have resolved this conflict in favor of work. Although men and women had the same incidence of reported recent medical errors, women were less likely to self-report a recent malpractice suit or to think that a fair resolution was reached. There was no gender difference in reported work-related pain. Multivariable analysis revealed that not enough family time and work-related pain were predictors for burnout in both men and women. Additional factors were associated with burnout in men, such as malpractice and electronic medical record dissatisfaction. Multivariable analysis revealed that work-related pain was an independent predictor for SI for the entire cohort., Conclusions: The prevalence of burnout among vascular surgeons is high. Women vascular surgeons have double the rates of SI compared with male vascular surgeons. Taken together, this study demonstrated that many of the same factors are associated with burnout in women and men, which include not enough family time, conflict between work and personal life, and work-related pain. Additional factors in men included conflict between work and family, work-related pain, and electronic medical record dissatisfaction., (Copyright © 2021 Society for Vascular Surgery.

Sex inequity in academic achievement was well documented before the COVID-19 pandemic, and evolving data suggest that women in academic surgery are disproportionately disadvantaged by the pandemic. This perspective piece reviews currently accepted solutions to the sex achievement gap, with their associated shortcomings. We also propose innovative strategies to overcoming barriers to sex equity in academic medicine that broadly fall into three categories: strategies to mitigate inequitable caregiving responsibilities, strategies to reduce cognitive load, and strategies to value uncompensated, impactful work. These approaches address inequities at the system-level, as opposed to the individual-level, lifting the burden of changing the system from women., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

The etiology of renal artery stenosis (RAS) and abdominal aortic coarctation (AAC) causing the midaortic syndrome (MAS), often resulting in renovascular hypertension (RVH), remains ill-defined. Neurofibromatosis type 1 (NF-1) is frequently observed in children with RVH. Consecutive pediatric patients (N = 102) presenting with RVH secondary to RAS with and without concurrent AAC were prospectively enrolled in a clinical data base, and blood, saliva and operative tissue, when available, were collected. Among the 102 children, 13 were having a concurrent clinical diagnosis of NF-1 (12.5%). Whole exome sequencing was performed for germline variant detection, and RNA-Seq analysis of NF1, MAPK pathway genes and MCP1 levels were undertaken in five NF-1 stenotic renal arteries, as well as control renal and mesenteric arteries from children with no known vasculopathy or NF-1. In 11 unrelated children with sequencing data, 11 NF1 genetic variants were identified, of which 10 had not been reported in gnomAD. Histologic analysis of NF-1 RAS specimens consistently revealed intimal thickening, disruption of the internal elastic lamina and medial thinning. Analysis of transcript expression in arterial lesions documented an approximately 5-fold reduction in NF1 expression, confirming heterozygosity, MAPK pathway activation and increased MCP1 expression. In summary, NF-1-related RVH in children is rare but often severe and progressive and, as such, important to recognize. It is associated with histologic and molecular features consistent with an aggressive adverse vascular remodeling process. Further research is necessary to define the mechanisms underlying these findings., (© The Author(s) 2021. Published by Oxford University Press. All rights reserved.

Objective: The contemporary medicolegal environment has been linked to procedure overuse, health care variation, and higher costs. For physicians accused of malpractice, there is also a personal toll. The objective of this study was to evaluate the prevalence of and risk factors for involvement in medical malpractice lawsuits among United States vascular surgeons, and to examine the association between these allegations with surgeon wellness., Methods: In 2018, the Society of Vascular Surgery (SVS) Wellness Task Force conducted a confidential survey of active members using a validated burnout assessment (Maslach Burnout Index) embedded into a questionnaire. This survey included questions related to medical errors and malpractice litigation. De-identified demographic, personal, and practice-related characteristics were assessed in respondents who reported malpractice allegations in the preceding 2 years, then compared with those without recent medicolegal litigation. Risk factors for malpractice allegations were identified (χ 2 , Kruskal-Wallis tests), and the association between malpractice allegations with wellness was examined. Multivariate logistic regression models were developed to identify independent risk factors for malpractice accusations., Results: Of 2905 active SVS members, 871 responses from practicing vascular surgeons were analyzed. A total of 161 (18.5%) were named in a malpractice lawsuit within 2 years. Malpractice allegations were significantly associated with surgeon burnout (odds ratio, 1.47; 95% confidence interval, 1.01-2.15; P = .041), but not with self-reported depression or suicidal ideation. The nature of malpractice claims included procedural errors (23.1%), failure to treat (18.8%), and error/delay in diagnosis (16.9%). Twenty percent of claims were settled prior to trial, and 19% were dismissed. Defendant vascular surgeons reported a "fair" resolution in 26.4% of closed cases. By unadjusted analysis, factors significantly associated with recent malpractice claims included mean age (51.7 ± 10.0 vs 49.3 ± 11.2 years; P = .0044) and mean years in practice (18.0 ± 10.7 vs 15.2 ± 11.8; P = .0007). Multivariate analysis revealed independent variables associated with malpractice allegations, including on-call frequency (P = .0178), recent medical errors (P = .0189), and male surgeons (P = .045)., Conclusions: Malpractice allegations are common for vascular surgeons and are significantly associated with surgeon burnout. Nearly 20% of survey respondents reported being named in a lawsuit within the preceding 2 years. Our findings underscore the need for SVS initiatives to provide counseling and peer support for vascular surgeons facing litigation., (Copyright © 2021 Society for Vascular Surgery.

Objective: Burnout and suicidality are known risks for vascular surgeons above other surgical subspecialties, with surgical trainees at risk for exposure to factors that increase burnout. This study aimed to inform initiatives to improve wellness by assessing the prevalence of hazards in vascular training (mistreatment, duty-hour violations) and the rates of wellness outcomes (burnout, thoughts of attrition/specialty change/suicide). We hypothesized that mistreatment and duty-hour violations would predispose trainees to increased burnout., Methods: We performed a cross-sectional study of residents and fellows enrolled in accredited United States vascular surgery training programs using a voluntary, confidential survey administered during the 2020 Vascular Surgery In-Training Examination. The primary outcome assessed was burnout symptoms reported on a weekly basis or more frequently. The rates of wellness outcomes were measured. The association of mistreatment and duty hours with the primary outcome was modeled with multivariable logistic regression., Results: A total of 475 residents and fellows who were enrolled in one of 120 vascular surgery training programs completed the survey (84.2% response rate). Of 408 trainees completing burnout survey items, 182 (44.6%) reported symptoms of burnout. Fewer trainees reported thoughts of attrition (n = 42 [10.0%], specialty change (n = 35 [8.4%]), or suicide (n = 22 [4.9%]). Mistreatment was reported by 191 vascular trainees (47.3%) and was more common in female trainees (n = 63 [48.5%] reporting monthly or more frequently) compared with male trainees (n = 51 [18.6%]; P < .001). Duty-hour violations were also more commonly reported by female trainees (n = 31 [21.4%] reporting 3+ months in violation) compared with male trainees (n = 50 [16.2%]; P = .002). After controlling for race/ethnicity, postgraduate year, program type, and geography, female trainees were less likely to report burnout (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28-0.86). Trainees experiencing mistreatment monthly or more were three times more likely to report burnout (OR, 3.09; 95% CI, 1.78-5.39). Frequency of duty-hour violations also increased the odds of reporting burnout (1-2 months in violation: OR, 2.09; 95% CI, 1.17-3.73; 3+ months in violation: OR, 3.95; 95% CI, 2.24-6.97)., Conclusions: Nearly one-half of vascular surgery trainees reported symptoms of burnout, which was associated with frequency of mistreatment and duty-hour violations. Interventions to improve well-being in vascular surgery must be tailored to the local training environment to address trainee experiences that contribute to burnout., (Copyright © 2021 Society for Vascular Surgery.

Objective: Integrated vascular surgery residency (IVSR) applicant perspective about the match process has been rarely studied, yet this has important implications on trainee recruitment. We sought to better understand the nature of the interview process and post-interview communication and its impact on students' ranking choices., Methods: A voluntary and anonymous survey was sent to students who matched to IVSR in 2020, inquiring about interviews, post-interview communications, and factors influencing students' rank lists., Results: Seventy of the 73 matched students completed the survey (96% response rate; 23 female and 47 male respondents). Applicants reported they were asked questions about other programs of interest (81.4%), top choice programs (65.7%), marital status (32.9%), family planning (7.1%), and religion (1.4%) during interviews. Female applicants were more frequently asked questions about family planning (17.4% vs 2.1%; P < .01) and marital status (52.5% vs 23.4%; P < .01) compared with male applicants. After interviews, 92.9% of applicants notified their top choice program of their ranking preference. Of applicants, 61.4% received post-interview communication with regards to ranking from at least one program, initiated by program directors in 81.3% of instances. Among these applicants, 58.1% reported that the post-interview communication had an impact on their rank list, and 46.5% matched at a program by which they were contacted. Of applicants, 5.7% were asked by a program to reveal their ranking of the program, and 11.4% were promised by a program to be ranked first if the applicant reciprocally ranked them first. Female and male applicants weighed program culture, operative volume, mentorship, and prestige equally in making their rank list. Male applicants weighed the sub-internship experience more significantly; however, female applicants weighed the sub-internship experience, personal relationships in certain cities, dedicated professional development years, and large female representation in the program more heavily (P < .02)., Conclusions: This study provides insight into the interview experience and impactful factors for the vascular surgery match. Both female and male applicants were asked a high number of questions about personal matters unrelated to medical school performance. Female applicants, however, experienced a higher proportion of these instances, particularly regarding family planning. These findings demonstrate the factors that are important to applicants in the match process and raises awareness of potential challenges in the interview and recruitment process., (Copyright © 2021 Society for Vascular Surgery.

The use of social media (SoMe) in medicine has demonstrated the ability to advance networking among clinicians and other healthcare staff, disseminate research, increase access to up-to-date information, and inform and engage medical trainees and the public at-large. With increasing SoMe use by vascular surgeons and other vascular specialists, it is important to uphold core tenets of our commitment to our patients by protecting their privacy, encouraging appropriate consent and use of any patient-related imagery, and disclosing relevant conflicts of interest. Additionally, we recognize the potential for negative interactions online regarding differing opinions on optimal treatment options for patients. The Society for Vascular Surgery (SVS) is committed to supporting appropriate and effective use of SoMe content that is honest, well-informed, and accurate. The Young Surgeons Committee of the SVS convened a diverse writing group of SVS members to help guide novice as well as veteran SoMe users on best practices for advancing medical knowledge-sharing in an online environment. These recommendations are presented here with the goal of elevating patient privacy and physician transparency, while also offering support and resources for infrequent SoMe users to increase their engagement with each other in new, virtual formats., (Copyright © 2021 Society for Vascular Surgery.

Background/objective: The unprecedented pandemic spread of the novel coronavirus has severely impacted the delivery of healthcare services in the United States and around the world, and has exposed a variety of inefficiencies in healthcare infrastructure. Some states have been disproportionately affected such as New York and Michigan. In fact, Detroit and its surrounding areas have been named as the initial Midwest epicenter where over 106,000 cases have been confirmed in April 2020., Method, Results and Conclusions: Facilities in Southeast Michigan have served as the frontline of the pandemic in the Midwest and in order to cope with the surge, rapid, and in some cases, complete restructuring of care was mandatory to effect change and attempt to deal with the emerging crisis. We describe the initial experience and response of 4 large vascular surgery health systems in Michigan to COVID-19.

Objective: The Public Service Loan Forgiveness (PSLF) program is an option to trainees to help alleviate federal education debt. The prevalence of PSLF utilization and how this may impact career decisions of trainees is unknown. The purpose of this study was to understand the prevalence, impact, and understanding of PSLF participation on trainees., Design: IRB-approved anonymous survey asking study subjects to report demographics, financial status, and reliance on PSLF. In addition, study subjects were asked to report their participation in PSLF, the possible impact of PSLF participation on career decisions, and to identify the qualifications needed to complete PSLF., Setting: Online anonymous survey., Participants: The survey was offered to all physician trainees in all specialties at the University of Texas, Southwestern, University of Wisconsin, Madison, and University of Michigan, Ann Arbor., Results: There were 934 respondents, yielding a 37.6% response rate. A total of 416/934 (44.5%) respondents were actively or planning on participating in the PSLF program with 175/934 (18.7%) belonging to a surgical specialty. Those belonging to a surgical specialty were more likely to be PSLF participants compared to medical specialties (53.1% versus 42.6%, p = 0.01). For those participating in PSLF, 82/416 (19.7%) stated this participation impacted career decisions. A total of 275/934 (29.4%) respondents obtained and 437/934 (46.8%) wanted to receive formal training/lectures in regards to the PSLF program. Of those actively or planning on participating in the PSLF program, only 58/416 (13.9%) were able to correctly identify all of the qualifications/criteria to complete the program., Conclusions: A large proportion of trainees rely on the PSLF program for education loan forgiveness with approximately 20% reporting participation impacted career decisions. Additionally, the majority may not fully understand PSLF criteria. Programs should strongly consider providing a formal education regarding PSLF to their trainees., (Copyright © 2021 Association of Program Directors in Surgery. All rights reserved.)

Fibromuscular dysplasia (FMD) is an arteriopathy associated with hypertension, stroke and myocardial infarction, affecting mostly women. We report results from the first genome-wide association meta-analysis of six studies including 1556 FMD cases and 7100 controls. We find an estimate of SNP-based heritability compatible with FMD having a polygenic basis, and report four robustly associated loci (PHACTR1, LRP1, ATP2B1, and LIMA1). Transcriptome-wide association analysis in arteries identifies one additional locus (SLC24A3). We characterize open chromatin in arterial primary cells and find that FMD associated variants are located in arterial-specific regulatory elements. Target genes are broadly involved in mechanisms related to actin cytoskeleton and intracellular calcium homeostasis, central to vascular contraction. We find significant genetic overlap between FMD and more common cardiovascular diseases and traits including blood pressure, migraine, intracranial aneurysm, and coronary artery disease., (© 2021.

Objective: Integrated vascular surgery residency is among the most competitive specialties, but little is known about the applicant perspective. The coronavirus disease 2019 outbreak impacted the 2021 integrated vascular surgery residency match because of travel restrictions. We sought to better understand pre-pandemic applicant recruitment strategies, logistics of away rotations, and the residency interview process to identify areas for improvement in the application process., Methods: An anonymous survey was sent to matched students in 2020, inquiring about motivations for pursuing vascular surgery (VS), logistic of away rotations and interviews, and factors influencing students' rank lists., Results: Seventy of the 73 matched students completed the survey (95.9% response rate). The median age was 27 (range, 25-41); 32.9% were female, 91.4% were U.S. medical students, and 77.1% were from institutions with a VS training program. Factors most strongly influencing the decision to choose VS as a career were interest in open vascular procedures, endovascular procedures, perceived job satisfaction, emerging technologies, and influence of a mentor. The prospect of the job market, future salary, and competitiveness of the application process had the least impact. Of the matched students, 82.9% completed an away rotation (median, 2; range, 1-4), with 51.7% of students paying a total cost of more than $2500. Fifty percent of students matched either at their home institution or where they had performed an away rotation. Students reported application submissions to a median of 50 programs (range, 1-70) and interviewed at 17 (range, 1-28), with 40% of students paying a total of more than $4000 for interview costs. The most significant factors affecting students' rank lists included program culture, open aortic surgical volume, geography, and complex endovascular procedure volume. Tours of facilities, resident salary, and male/female distribution had the least importance., Conclusions: Successfully matched applicants in 2020 prioritized operative case volume and program collegiality when ranking programs. Despite their high cost, away rotations played an important role in the Match, suggesting that time spent at potential institutions allowed ideal assessment of factors for students. The high average number of away rotations and in-person interviews performed in 2019-2020 was limited for the 2021 Match due to coronavirus disease 2019 restrictions. Programs will have to continue developing creative alternatives or additions to away rotations and the application processes to assure continued success in future post-pandemic Match cycles., (Copyright © 2021 Society for Vascular Surgery.

Autism spectrum disorder (ASD) often involves a wide range of co-occurring medical conditions ("comorbidities") and biochemical abnormalities such as oxidative stress and mitochondrial dysfunction. Nutritional supplements ("Nutraceuticals") are often used to treat both core ASD symptoms and comorbidities, but some have not yet been formally evaluated in ASD. The potential biological mechanisms of nutraceuticals include correction of micronutrient deficiencies due to a poor diet and support for metabolic processes such as redox regulation, mitochondrial dysfunction and melatonin production. This paper reports on the results of the National Survey on Treatment Effectiveness for Autism, focusing on nutraceuticals. The Survey involved 1286 participants from across the United States. Participants rated the overall perceived benefits and adverse effects of each nutraceutical, and also indicated the specific symptoms changed and adverse effects. From these ratings the top-rated nutraceuticals for each of 24 symptoms are listed. Compared to psychiatric and seizure medications rated through the same Survey, on average nutraceuticals had significantly higher ratings of Overall Benefit (1.59 vs. 1.39, p = 0.01) and significantly lower ratings of Overall Adverse Effects (0.1 vs. 0.9, p < 0.001). Folinic acid and vitamin B12 were two of the top-rated treatments. This study suggests that nutraceuticals may have clinical benefits and favorable adverse effect profiles.

Healthcare is most effectively delivered by high-performance teams, which require, not simply talent, but also diversity in their members, supported by a culture of equity that is open, supportive, and inclusive. Cognitive diversity offers a performance advantage, improving collective understanding and optimizing high-complexity problem solving. Diverse teams have been shown to outperform homogenous team, and this diversity, supplemented with equity and inclusion, yields a superior creative culture. High-performance teams rest on a foundation of standardized and inclusive recruitment practices. Standard recruitment procedures have been insufficient in broadening representation owing to the long-standing inequities and exclusion in medicine. As such, we have highlighted the opportunities for inclusive recruitment practices., (Copyright © 2021 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Introduction: Physician burnout has been linked to medical errors, decreased patient satisfaction, and decreased career longevity. In light of the increasing prevalence of cardiovascular disease, vascular surgeon burnout presents a legitimate public health concern owing to the impact on the adequacy of the vascular surgery workforce. The aims of this study were to define the prevalence of burnout among practicing vascular surgeons and identify factors that contribute to burnout to facilitate future Society for Vascular Surgery (SVS) initiatives to mitigate this crisis., Methods: In 2018, active SVS members were surveyed electronically and confidentially using the Maslach Burnout Inventory. The survey was tailored to explore specialty-specific issues, and to capture demographic and practice-related characteristics. Emotional exhaustion (EE) and depersonalization (DP) were analyzed as dimensions of burnout. Consistent with convention, surgeons with a high score on the DP and/or EE subscales of the Maslach Burnout Inventory were considered to have at least one manifestation of professional burnout. Risk factors associated with symptoms of burnout were identified using bivariate analyses (χ 2 , Kruskal-Wallis). Multivariate logistic regression models were developed to identify independent risk factors for burnout., Results: Of 2905 active SVS members, 960 responded to the survey (34% participation rate). After excluding retired surgeons and incomplete submissions, responses from 872 practicing vascular surgeons were analyzed. The mean age was 49.7 ± 11.0 years; the majority of respondents (81%) were male. Primary practice settings were academic (40%), community practice (41%), veteran's hospital (3.3%), active military practice (1.5%), or other. Years in practice averaged 15.7 ± 11.7. Overall, 41% of respondents had at least one symptoms of burnout (ie, high EE and/or high DP), 37% endorsed symptoms of depression in the past month, and 8% indicated they had considered suicide in the last 12 months. In unadjusted analysis, factors significantly associated with burnout (P < .05) included clinical work hours, on-call frequency, electronic medical record and documentation requirements, work-home conflict, and work-related physical pain. On multivariate analysis, age, work-related physical pain and work-home conflict were independent predictors for burnout., Conclusions: Symptoms of burnout and depression are common among vascular surgeons. Advancing age, work-related physical pain, and work-home conflict are independent predictors for burnout among vascular surgeons. Efforts to promote vascular surgeon well-being must address specialty-specific challenges, including the high prevalence of work-home conflict and occupational factors that contribute to work-related pain., (Copyright © 2020 Society for Vascular Surgery.
