A systematic review of existing appropriate use criteria in cardiovascular disease from the last 15 years.

Appropriate use criteria (AUC) aim to impact the provision of high-value care. This scoping review identified AUC regarding the procedural and operative treatment of cardiovascular disease and described the evolution of AUC in this space over time, including changes in the focus, strategy, and language of AUC. The summative presentation of these AUC identifies elements of AUC that may lead to successes in, and barriers to, implementation across disease processes, specialties, and societies. AUC topics include coronary artery disease, peripheral artery disease, valvular disease, venous disease, renal artery stenosis, and mesenteric ischemia, among others.

Co-Existing Vascular Surgery Integrated Residencies are Associated with Increased General Surgery Resident Proficiency and Autonomy in Vascular Cases.

BACKGROUND: Integrated vascular surgery residency positions have doubled more than the last decade. Studies have investigated the impact of co-existing subspecialty surgical training programs on case volume of general surgery residents (GSRs). However, no studies have explored the impact of subspecialty training on GSR operative competency. The aim of this study is to understand the impact of integrated residencies on operative performance and autonomy of GSR performing vascular procedures. METHODS: Autonomy and performance ratings of GSR participating in vascular surgery cases were collected from all institutions participating in the Society for Improving Medical Professional Learning application database from 2015 to 2023. Faculty and self-assessments of autonomy and performance on vascular cases performed by GSRs at programs with co-existing vascular integrated residency (VIR), vascular surgery fellowship (VSF), or no subspecialty vascular training (VX) were compared using Fisher's exact tests with Bonferroni corrections across training levels and case complexity. RESULTS: Eleven thousand one hundred seventy five assessments (26% at institutions with VIR, 46% VSF, and 28% VX) were submitted by 920 GSRs and 343 faculty. Senior GSRs at programs with VSF achieved lower autonomy than those with VIR (P = 0.049) or VX (P = 0.042) based on faculty assessment. GSRs achieved a level of "practice ready" at significantly higher rates when training at programs with VIR, and at the lowest rates with VSF (P < 0.001). However, self-perception of autonomy and performance was highest among GSRs at programs with VX compared with VIR and VSF (P < 0.001). CONCLUSIONS: The presence of VIR was associated with higher achievement of "practice ready" competency and higher levels of operative autonomy among senior GSRs performing vascular procedures. Shared-learning among peers and faculty expertise in teaching resident-level trainees may contribute to this finding.

Health Disparities Curricula in General Surgery Residency Programs: A Critical Scoping Review.

INTRODUCTION: In 2021, the structural determinants of health (SDOH) were added to the Accreditation Council of Graduate Medical Education common program requirements for all accredited residency programs, including general surgery. In this study, we sought to explore the current scope of, and concepts used in, health disparities curricula for general surgery residents, specifically investigating how general surgery residents learn about health disparities and the SDOH. METHODS: We searched PubMed, EMBASE, Education Research Complete (EBSCOhost), and Web of Science Core Collection using keywords related to health disparities and the SDOH. Inclusion criteria consisted of all studies published after 2005 that discussed health disparities curricula for Accreditation Council of Graduate Medical Education-accredited general surgery residency programs. Five thousand three hundred seventeen articles were screened using a two-phase process. Data extraction and analysis was performed using critical review methods. RESULTS: Seventeen articles were identified. Within these articles, seven unique health disparities curricula were found. All seven of the identified curricula employed cultural frameworks as methods to mitigate health disparities. Three curricula, all published after 2011, included education on the SDOH. A wide variety of educational methods were utilized; in-person didactics was the most common. CONCLUSIONS: In the current literature, culture continues to play a large role in health disparities training for general surgery residents. Though further efforts are needed to understand the methods used in programs that have not published scholarly work, it is imperative to ensure that residents are provided with the sociopolitical perspective needed to understand the SDOH and serve all patients, including those affected by health disparities.

Practice patterns of peripheral vascular interventions for peripheral artery disease in the office-based laboratory setting versus outpatient hospital.

OBJECTIVE: Controversy exists regarding the value and limitations of different sites of service for peripheral artery disease treatment. We aimed to examine practice patterns associated with peripheral vascular interventions (PVIs) performed in the office-based laboratory (OBL) vs outpatient hospital site of service using a nationally representative database. METHODS: Using 100% Medicare fee-for-service claims data, we identified all patients undergoing PVI for claudication or chronic limb-threatening ischemia (CLTI) between January 2017 and December 2022. We evaluated the associations of patient and procedure characteristics with site of service using multivariable hierarchical logistic regression. We used multinomial regression models to estimate the relative risk ratios (RRRs) of site of service and intervention type (angioplasty, stent, or atherectomy) and intervention anatomic level (iliac, femoropopliteal, or tibial) after adjusting for baseline patient characteristics and clustering by physician. RESULTS: Of 848,526 PVI, 485,942 (57.3%) were performed in an OBL. OBL use increased significantly over time from 48.3% in 2017 to 65.5% in 2022 (P < .001). Patients treated in OBLs were more likely to be Black (adjusted odds ratio [aOR], 1.14; 95% confidence interval [CI], 1.11-1.18) or other non-White race (aOR, 1.13; 95% CI, 1.08-1.18), have fewer comorbidities, and undergo treatment for claudication vs CLTI (aOR, 1.30; 95% CI, 1.26-1.33) compared with patients treated in outpatient hospital settings. Physicians with majority practice (>50% procedures) in an OBL were more likely to practice in urban settings (aOR, 21.58; 95% CI, 9.31-50.02), specialize in radiology (aOR, 18.15; 95% CI, 8.92- 36.92), and have high-volume PVI practices (aOR, 2.15; 95% CI, 2.10-2.29). The median time from diagnosis to treatment was shorter in OBLs, particularly for patients with CLTI (29 vs 39 days; P < .001). The OBL setting was the strongest predictor of patients receiving an atherectomy alone (adjusted RRR [aRRR] 6.67; 95% CI, 6.59-6.76) or atherectomy + stent (aRRR, 10.84; 95% CI, 10.64-11.05), and these findings were consistent in subgroup analyses stratified by PVI indication. The OBL setting was also associated with higher risk of tibial interventions for both claudication (aRRR, 3.18; 95% CI, 3.11-3.25) and CLTI (aRRR, 1.89; 95% CI, 1.86-1.92). The average reimbursement (including professional and facility fees) was slightly higher for OBLs compared with the hospital ($8742/case vs $8459/case; P < .001). However, in a simulated cohort resetting the OBL's intervention type distribution to that of the hospital, OBLs were associated with a hypothetical cost savings of $221,219,803 overall and $2602 per case. CONCLUSIONS: The OBL site of service was associated with greater access to care for non-White patients and a shorter time from diagnosis to treatment, but more frequently performed high-cost interventions compared with the outpatient hospital setting. The benefit to patients from improved access to peripheral artery disease care in OBL settings must be balanced with the potential limitations of receiving differential care.

Clinical factors associated with ultrashort length of stay in patients undergoing lower extremity bypass for peripheral arterial disease.

BACKGROUND: Length of stay (LOS) is a major driver of cost and resource utilization following lower extremity bypass (LEB). However, the variable comorbidity burden and mobility status of LEB patients makes implementing enhanced recovery after surgery pathways challenging. The aim of this study was to use a large national database to identify patient factors associated with ultrashort LOS among patients undergoing LEB for peripheral artery disease. METHODS: All patients undergoing LEB for peripheral artery disease in the National Surgical Quality Improvement Project database from 2011 to 2018 were included. Patients were divided into two groups based on the postoperative length of stay : ultrashort (≤2 days) and standard (>2 days). Thirty-day outcomes were compared using descriptive statistics, and multivariable logistic regression was used to identify patient factors associated with ultrashort LOS. RESULTS: Overall, 17,510 patients were identified who underwent LEB, of which 2678 patients (15.3%) had an ultrashort postoperative LOS (mean, 1.8 days) and 14,832 (84.7%) patients had a standard LOS (mean, 7.1 days). When compared to patients with a standard LOS, patients with an ultrashort LOS were more likely to be admitted from home (95.9% vs 88.0%; P < .001), undergo elective surgery (86.1% vs 59.1%; P < .001), and be active smokers (52.1% vs 40.4%; P < .001). Patients with an ultrashort LOS were also more likely to have claudication as the indication for LEB (53.1% vs 22.5%; P < .001), have a popliteal revascularization target rather than a tibial/pedal target (76.7% vs 55.3%; P < .001), and have a prosthetic conduit (40.0% vs 29.9%; P < .001). There was no significant difference in mortality between the two groups (1.4% vs 1.8%; P = .21); however, patients with an ultrashort LOS had a lower frequency of unplanned readmission (10.7% vs 18.8%; P < .001) and need for major reintervention (1.9% vs 5.6%; P < .001). On multivariable analysis, elective status (odds ratio , 2.66; 95% confidence interval [CI], 2.33-3.04), active smoking (OR, 1.18; 95% CI, 1.07-1.30), and lack of vein harvest (OR, 1.55; 95% CI, 1.41-1.70) were associated with ultrashort LOS. Presence of rest pain (OR, 0.57; 95% CI, 0.51-0.63), tissue loss (OR, 0.30; 95% CI, 0.27-0.34), and totally dependent functional status (OR, 0.54; 95% CI, 0.35-0.84) were associated negatively with an ultrashort LOS. When examining the subgroup of patients who underwent vein harvest, totally dependent (OR, 0.38; 95% CI, 0.19-0.75) and partially dependent (OR, 0.53; 95% CI, 0.32-0.88) functional status were persistently negatively associated with ultrashort LOS. CONCLUSIONS: Ultrashort LOS (≤2 days) after LEB is uncommon but feasible in select patients. Preoperative functional status and mobility are important factors to consider when identifying LEB patients who may be candidates for early discharge.

Lessons Learned from Coronary Revascularization Appropriateness Statements for Application to Peripheral Artery Disease.

Appropriate Use Criteria (AUC) are evidence-based criteria developed in a methodologically robust manner with the input of expert providers across a wide range of disciplines and practice settings. AUC have been successfully implemented in the diagnosis and management of a wide range of cardiovascular disease processes. AUC have demonstrated clear potential for influencing meaningful change in practice patterns with regards to high-value, high-quality care in cardiovascular pathologies. Potential for similar impact in the management of peripheral artery disease, specifically for patients presenting with intermittent claudication (IC), may be limited due to unique challenges. These challenges include multidisciplinary interventionalists, variability in existing AUC across specialties, and financial incentives influencing physician behavior. AUC serve to benefit patients by improving outcomes, and adoption of AUC is a critical step toward improving the quality of care provided to patients with IC. Societal support is necessary for effective AUC implementation.

Center-level outcomes following elective fenestrated endovascular aortic aneurysm repair in the Vascular Quality Initiative database.

OBJECTIVE: Hospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms, but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, postoperative outcomes, and 1-year survival following B-FEVAR. METHODS: Patients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair/Complex EVAR database were analyzed. Centers were grouped into quartiles by mean annual procedure volume. Multivariable regression was used to evaluate the effect of center volume on in-hospital mortality adjusting for baseline and procedural characteristics. Kaplan-Meier estimation, log rank test, and mixed effects Cox regression were used to evaluate 1-year survival. RESULTS: A total of 4302 adult elective F-BEVAR procedures were identified at a total of 163 centers. In-hospital mortality did not differ by hospital volume (quartile [Q]1 = 35/1059 [3.3%]; Q2 = 30/1063 [2.8%]; Q3 = 33/1120 [2.9%]; and Q4 = 44/1060 [4.2%]; P = .308). The high volume group had a higher rate of major complication (Q1 = 14.9%; Q2 = 12.8%; Q3 = 13.3%; and Q4 = 20.1%; adjusted P < .001). Physician-modified grafts were more frequently employed in high-volume centers (Q1 = 4.5%; Q2 = 18.7%; Q3 = 11.3%; and Q4 = 19.2%; P < .001), with a decreased incidence of any endoleak noted at the end of the procedure (Q1 = 34.9%; Q2 = 32.8%; Q3 = 30.0%; and Q4 = 29.0%; P = .003). In the multivariable analysis, in-hospital mortality was not associated with center volume, comparing very low volume to medium- and high-volume centers (odds ratio [95% confidence interval] vs Q4: Q1 = 1.1 [0.6-1.9], Q2 = 0.6 [0.4-1.1], and Q3 = 0.9 [0.5-1.5]; all P > .05). No significant difference was found in 1-year survival between center volume groups. CONCLUSIONS: In-hospital mortality is not associated with procedure volume within centers performing complex endovascular aortic repair. However, complication rates and endoleak may be associated with procedure volume. Long-term outcomes by annualized procedure volume, specifically graft durability and sac expansion, should be investigated.

Gender differences in autonomy and performance assessments in a national cohort of vascular surgery trainees.

OBJECTIVE: Gender disparities in surgical training and assessment are described in the general surgery literature. Assessment disparities have not been explored in vascular surgery. We sought to investigate gender disparities in operative assessment in a national cohort of vascular surgery integrated residents (VIRs) and fellows (VSFs). METHODS: Operative performance and autonomy ratings from the Society for Improving Medical Professional Learning (SIMPL) application database were collected for all vascular surgery participating institutions from 2018 to 2023. Logistic generalized linear mixed models were conducted to examine the association of faculty and trainee gender on faculty and self-assessment of autonomy and performance. Data were adjusted for post-graduate year and case complexity. Random effects were included to account for clustering effects due to participant, program, and procedure. RESULTS: One hundred three trainees (n = 63 VIRs; n = 40 VSFs; 63.1% men) and 99 faculty (73.7% men) from 17 institutions (n = 12 VIR and n = 13 VSF programs) contributed 4951 total assessments (44.4% by faculty, 55.6% by trainees) across 235 unique procedures. Faculty and trainee gender were not associated with faculty ratings of performance (faculty gender: odds ratio [OR], 0.78; 95% confidence interval [CI], 0.27-2.29; trainee gender: OR, 1.80; 95% CI, 0.76-0.43) or autonomy (faculty gender: OR, 0.99; 95% CI, 0.41-2.39; trainee gender: OR, 1.23; 95% CI, 0.62-2.45) of trainees. All trainees self-assessed at lower performance and autonomy ratings as compared with faculty assessments. However, women trainees rated themselves significantly lower than men for both autonomy (OR, 0.57; 95% CI, 0.43-0.74) and performance (OR, 0.40; 95% CI, 0.30-0.54). CONCLUSIONS: Although gender was not associated with differences in faculty assessment of performance or autonomy among vascular surgery trainees, women trainees perceive themselves as performing with lower competency and less autonomy than their male colleagues. These findings suggest utility for exploring gender differences in real-time feedback delivered to and received by trainees and targeted interventions to align trainee self-perception with actual operative performance and autonomy to optimize surgical skill acquisition.
