RESUMO
INTRODUCTION: Occlusion after infra-inguinal bypass surgery for peripheral artery disease is a major complication with potentially devastating consequences. In this descriptive analysis, we sought to describe the natural history and explore factors associated with long-term major amputation-free survival following occlusion of a first-time infra-inguinal bypass. METHODS: Using a prospective database from a tertiary care vascular center, we conducted a retrospective cohort study of all patients with peripheral artery disease who underwent a first-time infra-inguinal bypass and subsequently suffered a graft occlusion (1997-2021). The primary outcome was longitudinal rate of major amputation-free survival after bypass occlusion. Cox proportional hazard models were used to generate hazard ratios (HRs) and 95% confidence intervals (CIs) to explore predictors of outcomes. RESULTS: Of the 1318 first-time infra-inguinal bypass surgeries performed over the study period, 255 bypasses occluded and were included in our analysis. Mean age was 66.7 (12.6) years, 40.4% were female, and indication for index bypass was chronic limb threatening ischemia (CLTI) in 89.8% (n = 229). 48.2% (n = 123) of index bypass conduits used great saphenous vein, 29.0% (n = 74) prosthetic graft, and 22.8% (n = 58) an alternative conduit. Median (interquartile range) time to bypass occlusion was 6.8 (2.3-19.0) months, and patients were followed for median of 4.3 (1.7-8.1) years after bypass occlusion. Following occlusion, 38.04% underwent no revascularization, 32.94% graft salvage procedure, 25.1% new bypass, and 3.92% native artery recanalization. Major amputation-free survival following occlusion was 56.9% (50.6%-62.8%) at 1 y, 37.1% (31%-43.3%) at 5 y, and 17.2% (11.9%-23.2%) at 10 y. In multivariable analysis, factors associated with lower amputation-free survival were older age, female sex, advanced cardiorenal comorbidities, CLTI at index procedure, CLTI at time of occlusion, and distal index bypass outflow. Initial treatment after occlusion with both a new surgical bypass (HR 0.44, CI: 0.29-0.67) or a graft salvage procedure (HR 0.56, CI: 0.38-0.82) showed improved amputation-free survival. One-year rate of major amputation or death were 59.8% (50.0%-69.6%) for those who underwent no revascularization, 37.9% (28.7%-49.0%) for graft salvage, and 26.7% (17.6%-39.5%) for new bypass. CONCLUSIONS: Long-term major amputation-free survival is low after occlusion of a first-time infra-inguinal bypass. While several nonmodifiable risk factors were associated with lower amputation-free survival, treatment after graft occlusion with either a new bypass or a graft salvage procedure may improve longitudinal outcomes.

OBJECTIVE: Despite the emergence of endovascular aneurysm repair (EVAR) as the most common approach to abdominal aortic aneurysm repair, open aneurysm repair (OAR) remains an important option. This study seeks to define the indications for OAR in the EVAR era and how these indicatioxns effect outcomes. METHODS: A retrospective cohort study was performed of all OAR at a single institution from 2004 to 2019. Preoperative computed tomography scans and operative records were assessed to determine the indication for OAR. These reasons were categorized into anatomical contraindications, systemic factors (connective tissue disorders, contraindication to contrast dye), and patient or surgeon preference (patients who were candidates for both EVAR and OAR). Perioperative and long-term outcomes were compared between the groups. RESULTS: We included 370 patients in the analysis; 71.6% (265/370) had at least one anatomic contraindication to EVAR and 36% had two or more contraindications. The most common anatomic contraindications were short aortic neck length (51.6%), inadequate distal seal zone (19.2%), and inadequate access vessels (15.7%). The major perioperative complication rate was 18.1% and the 30-day mortality was 3.0%. No single anatomic factor was identified as a predictor of perioperative complications. Sixty-one patients (16.5%) underwent OAR based on patient or surgeon preference; these patients were younger, had lower incidences of coronary artery disease and chronic obstructive pulmonary disease, and were less likely to require suprarenal cross-clamping compared with patients who had anatomic and/or systemic contraindications to EVAR. The patient or surgeon preference group had a lower incidence of perioperative major complications (8.2% vs 20.1%; P = .034), shorter length of stay (6 days vs 8 days; P < .001) and no 30-day mortalities. The multivariable adjusted risk for 15-year mortality was lower for patient or surgeon preference patients (adjusted hazard ratio, 0.44; 95% confidence interval, 0.24-0.80; P = .007) compared with those anatomic or systemic contraindications. CONCLUSIONS: Within a population of patients who did not meet instruction for use criteria for EVAR, no single anatomic contraindication was a marker for worse outcomes with OAR. Patients who were candidates for both aortic repair approaches but elected to undergo OAR owing to patient or surgeon preference have very low 30-day mortality and morbidity, and superior long-term survival rates compared with those patients who underwent OAR owing to anatomic and/or systemic contraindications to EVAR.

OBJECTIVE: We review the existing research on environmentally sustainable surgical practices to enable SAO to advocate for improved environmental sustainability in operating rooms across the country. SUMMARY OF BACKGROUND DATA: Climate change refers to the impact of greenhouse gases emitted as a byproduct of human activities, trapped within our atmosphere and resulting in hotter and more variable climate patterns.1 As of 2013, the US healthcare industry was responsible for 9.8% of the country's emissions2; if it were itself a nation, US healthcare would rank 13th globally in emissions.3 As one of the most energy-intensive and wasteful areas of the hospital, ORs drive this trend. ORs are 3 to 6 times more energy intensive than clinical wards.4 Further, ORs and labor/delivery suites produce 50%-70% of waste across the hospital.5,6 Due to the adverse health impacts of climate change, the Lancet Climate Change Commission (2009) declared climate change "the biggest global health threat of the 21st century" and predicted it would exacerbate existing health disparities for minority groups, children and low socioeconomic patients.7. METHODS/RESULTS: We provide a comprehensive narrative review of published efforts to improve environmental sustainability in the OR while simultaneously achieving cost-savings, and highlight resources for clinicians interested in pursuing this work. CONCLUSION: Climate change adversely impacts patient health, and disproportionately impacts the most vulnerable patients. SAO contribute to the problem through their resource-intensive work in the OR and are uniquely positioned to lead efforts to improve the environmental sustainability of the OR.

BACKGROUND: Wound complications after open infrainguinal revascularization are a frequent cause of patient morbidity, resulting in increased healthcare costs. The purpose of the present study was to assess the effects of closed incision negative pressure therapy (ciNPT) on groin wound complications after infrainguinal bypass and femoral endarterectomy. METHODS: A total of 242 patients who had undergone infrainguinal bypass (n = 124) or femoral endarterectomy (n = 118) at five academic medical centers in New England from April 2015 to August 2019 were randomized to ciNPT (PREVENA; 3M KCI, St Paul, Minn; n = 118) or standard gauze (n = 124). The primary outcome measure was a composite endpoint of groin wound complications, including surgical site infections (SSIs), major noninfectious wound complications, or graft infections within 30 days after surgery. The secondary outcome measures included 30-day SSIs, 30-day noninfectious wound complications, readmission for wound complications, significant adverse events, and health-related quality of life using the EuroQoL 5D-3L survey. RESULTS: The ciNPT and control groups had similar demographics (age, 67 vs 67 years, P = .98; male gender, 71% vs 70%, P = .86; white race, 93% vs 93%, P = .97), comorbidities (previous or current smoking, 93% vs 94%, P = .46; diabetes, 41% vs 48%, P = .20; renal insufficiency, 4% vs 7%, P = .31), and operative characteristics, including procedure type, autogenous conduit, and operative time. No differences were found in the primary composite outcome at 30 days between the two groups (ciNPT vs control: 31% vs 28%; P = .55). The incidence of SSI at 30 days was similar between the two groups (ciNPT vs control: 11% vs 12%; P = .58). Infectious (13.9% vs 12.6%; P = .77) and noninfectious (20.9% vs 17.6%; P = .53) wound complications at 30 days were also similar for the ciNPT and control groups. Wound complications requiring readmission also similar between the two groups (ciNPT vs control: 9% vs 7%; P = .54). The significant adverse event rates were not different between the two groups (ciNPT vs control: 13% vs 16%; P = .53). The mean length of the initial hospitalization was the same for the ciNPT and control groups (5.2 vs 5.7 days; P = .63). The overall health-related quality of life was similar at baseline and at 14 and 30 days postoperatively for the two groups. Although not powered for stratification, we found no differences among the subgroups in gender, obesity, diabetes, smoking, claudication, chronic limb threatening ischemia, bypass, or endarterectomy. On multivariable analysis, no differences were found in wound complications at 30 days for the ciNPT vs gauze groups (odds ratio, 1.4; 95% confidence interval, 0.8-2.6; P = .234). CONCLUSIONS: In contrast to other randomized studies, our multicenter trial of infrainguinal revascularization found no differences in the 30-day groin wound complications for patients treated with ciNPT vs standard gauze dressings. However, the SSI rate was lower in the control group than reported in other studies, suggesting other practice patterns and processes of care might have reduced the rate of groin infections. Further study might identify the subsets of high-risk patients that could benefit from ciNPT.

BACKGROUND: Shared decision making and patient-centred communication have become part of pre-procedural decisions and perioperative care across medical specialties. However, gaps exist in patient communication about the implanted device received and the benefits in sharing information about their procedure and device. OBJECTIVE: To understand the patients' knowledge of identifying information for their implanted devices and perspectives on sharing their implanted device information. METHODS: Four focus groups were conducted with patients who had received a cardiac or vascular implanted device from one of the study sites within the previous 6 months. Data were transcribed and thematically analysed. RESULTS: Five themes emerged: lack of awareness of identifying information on implanted devices; value of information on implanted devices; varying trust with sharing device information; perceived risk with sharing device information; and lack of consensus on a systematic process for tracking implanted devices. DISCUSSION: Patients desire post-procedural information on their implanted device and a designated plan for longitudinal follow-up, but lack trust and perceive risk with broadly sharing their implanted device information. CONCLUSION: After receiving an implanted device, post-procedural patient communication needs to be expanded to include identifying information on the device including the unique device identifier, how long-term tracking will be supported and the process for notification in case of a problem with the device. This communication should also include education on how sharing device information supports patients' long-term health care, post-market safety surveillance and research. PATIENT OR PUBLIC CONTRIBUTION: The research team included members who were also patients with implanted devices.

BACKGROUND: Preoperative magnetic resonance imaging (MRI) utilization in breast cancer treatment has increased significantly over the past 2 decades, but its use continues to have interprovider variability and disputed clinical indications. OBJECTIVE: The aim of this study was to evaluate non-clinical factors associated with preoperative breast MRI utilization. METHODS: This study utilized TRICARE claims data from 2006 to 2015. TRICARE provides health benefits for active duty service members, retirees, and their dependents at both military (direct care with salaried physicians) and civilian (purchased care under fee-for-service structure) facilities. We studied patients aged 25-64 years with a breast cancer diagnosis who had undergone mammogram/ultrasound (MMG/US) alone or with subsequent breast MRI prior to surgery. Facility characteristics included urban-rural location according to the National Center for Health Statistics classification. Adjusted multivariable logistic regression tests were used to identify independent factors associated with preoperative breast MRI utilization. RESULTS: Of the 25,392 identified patients, 64.7% (n = 16,428) received preoperative MMG/US alone, while 35.3% (n = 8964) underwent additional MRI. Younger age, Charlson Comorbidity Index score ≥ 2, active duty or retired beneficiary category, officer rank (surrogate for socioeconomic status), Air Force service branch, metropolitan location, and purchased care were associated with an increased likelihood of preoperative MRI utilization. Non-metropolitan location and Navy service branch were associated with decreased MRI use. CONCLUSION: After controlling for expected clinical risk factors, patients were more likely to receive additional MRI when treated at metropolitan facilities or through the fee-for-service system. Both associations may point toward non-clinical incentives to perform MRI in the treatment of breast cancer.

OBJECTIVE: Severe aortoiliac occlusive disease is a relative contraindication for endovascular aneurysm repair, owing to an association with high stent graft-related complication and reintervention rates in this population. Open AAA repair requiring aortofemoral bypass (AFB), however, may represent a unique population with differing outcomes from standard open repair. We sought to compare the demographic and procedural characteristics, as well as outcomes of patients undergoing standard intra-abdominal repairs (STD) versus those requiring AFB. METHODS: Using a prospectively maintained database, we retrospectively identified patients who underwent open AAA repair from 1994 to 2017. A total of 1087 consecutive cases were performed consisting of 981 STD (681 tube graft, 300 aortoiliac) and 106 AFB cases. Demographics, procedural data, postoperative complications, and long-term survival were analyzed. RESULTS: The AFB cohort had more women (39.0 vs 22.8%; P = .001) and higher rates of hypertension (81.1 vs 69.8%; P = .015), chronic obstructive pulmonary disease (28.3 vs 17.4%; P = .006), and smoking (50.9 vs 36%; P = .002). The AFB group had smaller mean aortic (5.22 vs 5.77 cm; P = .001) and graft (17.08 vs 18.2 mm; P = .001) diameters. Proximal clamp position and blood loss were equivalent, although total anesthesia time was longer (295 vs 234 minutes; P = .001) in the AFB cohort. Overall 30-day postoperative morbidity (38.7 vs 24.8%; P = .002) was higher in the AFB group. Specifically, postoperative renal insufficiency (8.2 vs 3.4%; P = .032), wound infection (5.7 vs 1.2%; P = .005), and hematoma/seroma (5.7 vs 1.2%; P = .003) were more likely. Hospital length of stay was longer for AFB (11.9 vs 9.9 days; P = .007). The 30-day mortality (0.9% AFB vs 1.8% STD; P = .50) and major morbidity (17 vs 11.5%; P = .10) did not differ. Reintervention rate within 30 days of the initial surgery (12.3 vs 4.6; P = .001) and overall (33 vs 18.9%; P = .001) was higher in the AFB group. Long-term survival was lower in the AFB group (5-year survival: 63.1% AFB vs 71.9% STD; hazard ratio 0.76, log-rank P = .047). Multivariate regression analysis identified age, comorbid conditions, and aneurysm characteristics-rather than repair type-as independent predictors of 30-day reintervention and mortality at 5 years. CONCLUSIONS: Patients requiring AFB for AAA owing to associated iliac occlusive disease have more preoperative comorbidities, postoperative complications, a longer length of stay, reintervention rates and shorter 5-year survival. Patient and aneurysm characteristics rather than surgical repair type appear to be responsible for these differences. Nevertheless, 30-day mortality and major morbidity were comparable, making AFB an attractive alternative to endovascular aneurysm repair in patients with advanced iliac occlusive disease.

OBJECTIVE: Vascular surgeons are frequently called on to provide emergency assistance to surgical colleagues. Whereas previous studies have included elective preoperative vascular consultations, we sought to characterize the breadth of assistance provided during unplanned intraoperative consultations at a single tertiary academic center. METHODS: We queried our institutional billing department during a 15-year period and reviewed the records (January 1, 2002-December 31, 2016) and identified unanticipated unplanned vascular surgery intraoperative consultations from all surgical services. Patients' demographics and comorbidities were recorded along with the consulting services, type of index operation, reasons for vascular consultation, regions of anatomic interventions, type of vascular interventions performed, and outcomes achieved. RESULTS: There were 419 emergency intraoperative consultations identified. Patients were 51% male, with an average age of 57 years and body mass index of 28.3 kg/m2. The most frequently consulting subspecialties included surgical oncology (n = 139 [33.2%]), cardiac surgery (n = 82 [19.6%]), and orthopedics (n = 44 [10.5%]). Index cases were elective/nonurgent (n = 324 [77.3%]), urgent (n = 27 [6.4%]), and emergent (n = 68 [16.2%]), with a majority involving tumor resection (n = 240 [57.3%]). The primary reasons for vascular consultation were revascularization (n = 213 [50.8%]), control of bleeding (n = 132 [31.5%]), assistance with dissection or exposure (n = 46 [11%]), embolic protection (n = 24 [5.7%]), and other (n = 4 [1.1%]). The primary blood vessel and anatomic field of intervention were categorized. Most cases (n = 264 [63%]) included preservation of blood flow, including primary arterial repair (n = 181 [43.2%]), patch angioplasty (n = 83 [19.8%]), bypass (n = 63 [15%]), and thrombectomy (n = 38 [9.1%]). Postoperative mean length of stay was 15 days, with 30-day and 1-year mortality of 7.2% and 26.5%. CONCLUSIONS: Vascular surgeons are called on to provide unplanned open surgical consultations for a wide variety of specialties over wide-ranging anatomic regions, employing a variety of skills and techniques. This study testifies to the essential services supplied to hospitals and our surgical colleagues along with the broad skills and training necessary for modern vascular surgeons.

BACKGROUND: Epidural analgesia (EA) is frequently used as an adjuvant to general anesthesia (GA) for improved postoperative analgesia and reduced rates of cardiac, pulmonary, and renal complications. However, only a few studies have examined EA-GA specifically during open abdominal aortic aneurysm (AAA) repair. The effects of EA-GA specifically during open AAA repair regarding postoperative outcomes are unknown. This study was performed to evaluate postoperative outcomes in patients undergoing open AAA repair with EA-GA versus GA alone. METHODS: We performed a retrospective analysis for patients undergoing surgery between January 1, 2014 and December 31, 2016 using the National Surgical Quality Improvement Program (NSQIP) database. Propensity score matching was used to establish cohorts for analysis. Multivariable logistic regression was performed to determine significant perioperative outcomes for each anesthesia type. A total of 2,171 patients underwent open AAA repair in our date range; we excluded emergent and ruptured AAA. A total of 2,145 patients were included in our analysis, of whom 653 patients received EA-GA and 1,492 patients received GA only. RESULTS: Major postoperative outcomes included mortality, pulmonary cardiac and renal complications, infections, thrombosis, and blood transfusion requirement (including Cell-Saver usage). Additional overall outcomes included hospital length of stay, return to the operating room, and readmission. Patients in EA + GA and GA alone groups were comparable regarding demographics, functional status, and comorbidities. Decreased odds of readmission was observed in EA + GA compared with GA (0.49, 95% CI [0.28-0.86]; P = 0.014); and increased odds of receiving a blood transfusion was observed in those who underwent EA + GA (1.63, 95% CI [1.23-2.14]; P = 0.001). No difference was observed between patients who had an AAA repair with EA + GA versus GA alone with regard to mortality, return to operating room, major pulmonary, cardiac, renal, or infectious complications. CONCLUSIONS: EA + GA was not associated with decreased mortality or decreased rates of major postoperative pulmonary, cardiac, or renal complications. EA + GA was associated with increased transfusion requirements and decreased rates of hospital readmission.

BACKGROUND: Index length of stay (LOS) and readmissions are viewed as important quality measures. However, these metrics represent competing demands as an inordinate reduction in LOS may lead to unplanned readmissions. We sought to assess the optimal LOS associated with the lowest 90-d readmission rate following discharge after common surgical procedures. MATERIALS AND METHODS: This was a retrospective study relying on Tricare claims. We identified all eligible adult patients (18-64 y) receiving a series of common surgical procedures between 2006 and 2014. We used a generalized additive model with spline regression to determine the optimal LOS associated with the lowest 90-d risk of readmission. RESULTS: Ninety-day readmission rates varied from 6.03% to 34.69%. Most procedures exhibited a logit linear relationship, with the lowest risk of readmission evident on postoperative day-1 and increasing thereafter. Among the more invasive procedures (e.g., esophagectomy and radical cystectomy), a U-shaped relationship was realized, indicating that expedited discharge would increase the potential for readmission as would any extended hospital LOS. For these procedures, the ideal index LOS appeared to be 6-7 d for radical cystectomy and 12-13 d for esophagectomy. CONCLUSIONS: Our results support the practice of discharging patients as soon as clinically feasible after hip and knee arthroplasty, lumbar spine surgery, hernia repair, appendectomy, nephrectomy, and colectomy. Among esophagectomy or radical cystectomy, there is a well-defined optimal index admission period and discharge outside this window appears to be detrimental. Our results suggest that invasive procedures appear to possess a unique "signature" when it comes to optimal LOS.

BACKGROUND: Racial disparities in colorectal cancer (CRC) screening are frequently attributed to variations in insurance status. The objective of this study was to ascertain whether universal insurance would lead to more equitable utilization of CRC screening for black patients in comparison with white patients. METHODS: Claims data from TRICARE (insurance coverage for active, reserve, and retired members of the US Armed Services and their dependents) for 2007-2010 were queried for adults aged 50 years in 2007, and they were followed forward in time for 4 years (ages, 50-53 years) to identify their first lower endoscopy and/or fecal occult blood test (FOBT). Variations in CRC screening were compared with descriptive statistics and multivariate logistic regression. RESULTS: Among the 24,944 patients studied, 69.2% were white, 20.3% were black, 4.9% were Asian, and 5.6% were other. Overall, 54.0% received any screening: 83.7% received endoscopy, and 16.3% received FOBT alone. Compared with whites, black patients had higher screening rates (56.5%) and had 20% higher risk-adjusted odds of being screened (95% confidence interval [CI], 1.11-1.29). Asian patients had a likelihood of screening similar to that of white patients (odds ratio [OR], 1.06; 95% CI, 0.92-1.23). Females (OR, 1.20; 95% CI, 1.10-1.33), active-duty personnel (OR, 1.15; 95% CI, 1.06-1.25), and officers (OR, 1.28; 95% CI, 1.18-1.37) were also more likely to be screened. CONCLUSION: Within an equal-access, universal health care system, black patients had higher rates of CRC screening in comparison with prior reports and even in comparison with white patients within the population. These findings highlight the need to understand and develop meaningful approaches for promoting more equitable access to preventative care. Moreover, equal-access, universal health insurance for both the military and civilian populations can be presumed to improve access for underserved minorities.

OBJECTIVE: The clinical impact of peripheral arterial disease (PAD) is well characterized and is associated with significant morbidity and mortality. Health care-related expenditures among individuals with PAD, particularly for patients, are not well described. METHODS: Health care-related expenditure data from the 2011 to 2014 Agency for Healthcare Research and Quality Medical Expenditure Panel Surveys were analyzed for individuals with a diagnosis of PAD compared with U.S. adults 40 years of age and older. Weighted average annual expenditures were estimated using a multivariable generalized linear model. Subanalyses were also performed for out-of-pocket (OOP) expenditures by insurance type. RESULTS: Adjusted for age, gender, and race, individuals with a diagnosis of PAD (weighted n = 640,098) had significantly higher average annual health care-related expenditures compared with the U.S. adult population as a whole (weighted n = 148,387,362). Average annual expenditures per individual for patients with PAD were $11,553 (95% confidence interval [CI], $8137-$14,968) compared with only $4219 (95% CI, $4064-$4375; P < .001) for those without. Expenditures were driven by increased prescription medication expenditures as well as by expenditures for inpatient care, outpatient hospital-based care, and outpatient office-based care. Individuals with PAD had significantly higher OOP prescription medication expenditures ($386 [95% CI, $258-$515] vs $192 [95% CI, $183-$202]; P = .003), which varied by insurance type, ranging from $179 (95% CI, $70-$288) for those with Medicare to $1196 (95% CI, $106-$2244) for those without insurance, although this difference did not reach significance. CONCLUSIONS: Individuals with a diagnosis of PAD have higher health care-related expenditures and OOP expenses compared with other US adults. These expenditures compound lost wages, care by family members, and lost opportunity costs, increasing the burden carried by patients with PAD.

BACKGROUND: Decision-making related to the care of patients with an abdominal aortic aneurysm (AAA) is complex. Aneurysms present with varying risks of rupture, and patient-specific factors influence anticipated life expectancy, operative risk, and need to intervene. Careful attention to the choice of operative strategy along with optimal treatment of medical comorbidities is critical to achieving excellent outcomes. Moreover, appropriate postoperative surveillance is necessary to minimize subsequent aneurysm-related death or morbidity. METHODS: The committee made specific practice recommendations using the Grading of Recommendations Assessment, Development, and Evaluation system. Three systematic reviews were conducted to support this guideline. Two focused on evaluating the best modalities and optimal frequency for surveillance after endovascular aneurysm repair (EVAR). A third focused on identifying the best available evidence on the diagnosis and management of AAA. Specific areas of focus included (1) general approach to the patient, (2) treatment of the patient with an AAA, (3) anesthetic considerations and perioperative management, (4) postoperative and long-term management, and (5) cost and economic considerations. RESULTS: Along with providing guidance regarding the management of patients throughout the continuum of care, we have revised a number of prior recommendations and addressed a number of new areas of significance. New guidelines are provided for the surveillance of patients with an AAA, including recommended surveillance imaging at 12-month intervals for patients with an AAA of 4.0 to 4.9 cm in diameter. We recommend endovascular repair as the preferred method of treatment for ruptured aneurysms. Incorporating knowledge gained through the Vascular Quality Initiative and other regional quality collaboratives, we suggest that the Vascular Quality Initiative mortality risk score be used for mutual decision-making with patients considering aneurysm repair. We also suggest that elective EVAR be limited to hospitals with a documented mortality and conversion rate to open surgical repair of 2% or less and that perform at least 10 EVAR cases each year. We also suggest that elective open aneurysm repair be limited to hospitals with a documented mortality of 5% or less and that perform at least 10 open aortic operations of any type each year. To encourage the development of effective systems of care that would lead to improved outcomes for those patients undergoing emergent repair, we suggest a door-to-intervention time of <90 minutes, based on a framework of 30-30-30 minutes, for the management of the patient with a ruptured aneurysm. We recommend treatment of type I and III endoleaks as well as of type II endoleaks with aneurysm expansion but recommend continued surveillance of type II endoleaks not associated with aneurysm expansion. Whereas antibiotic prophylaxis is recommended for patients with an aortic prosthesis before any dental procedure involving the manipulation of the gingival or periapical region of teeth or perforation of the oral mucosa, antibiotic prophylaxis is not recommended before respiratory tract procedures, gastrointestinal or genitourinary procedures, and dermatologic or musculoskeletal procedures unless the potential for infection exists or the patient is immunocompromised. Increased utilization of color duplex ultrasound is suggested for postoperative surveillance after EVAR in the absence of endoleak or aneurysm expansion. CONCLUSIONS: Important new recommendations are provided for the care of patients with an AAA, including suggestions to improve mutual decision-making between the treating physician and the patients and their families as well as a number of new strategies to enhance perioperative outcomes for patients undergoing elective and emergent repair. Areas of uncertainty are highlighted that would benefit from further investigation in addition to existing limitations in diagnostic tests, pharmacologic agents, intraoperative tools, and devices.

OBJECTIVE: Wound complications (WCs) after lower extremity arterial surgery (LEAS) are common, resulting in readmissions and reinterventions. Whereas diabetes and obesity are known risk factors for WCs, gender-specific variability in body fat distribution (android vs gynoid) may drive differential risks of WCs after LEAS. We analyzed the independent and synergistic effects of gender and body mass index (BMI) on WCs. METHODS: We performed a retrospective review of prospectively collected data from a published, randomized, multicenter trial assessing the incidence of WCs (dehiscence, surgical site infections, seroma, and hematoma) after LEAS. Postoperative outcomes were compared between genders. A multivariable regression model assessed the impact of gender and BMI on WCs. Subanalysis focused on the synergy of gender and body habitus, groin-only incisions, and clinical outcomes. RESULTS: There were 502 patients who underwent LEAS between October 2010 and September 2013. The cohort was elderly (67.6 ± 10.5 years), mostly male (72%), and overweight (BMI, 27.6 ± 5.7); 225 (45%) patients had a groin-only incision. In 171 patients (37.9%), a WC developed within 30 days, 85% of which were infectious in etiology. On multivariable regression, obesity (odds ratio [OR], 2.10; 95% confidence interval [CI], 1.17-3.77), morbid obesity (OR, 2.87; 95% CI, 1.32-6.23), and female gender (OR, 1.17; 95% CI, 1.06-2.75) were independent predictors of infectious WCs at 30 days. When stratified by groin-only incision, BMI was no longer significant, but female gender (OR, 2.70; 95% CI, 1.24-5.87) was predictive of infectious WCs at 30 days. There was no synergistic effect of BMI and gender on WCs. CONCLUSIONS: WCs are common after LEAS. BMI is an independent risk factor for the development of any WC. Female gender, a potential surrogate for high hip to waist ratio body habitus, is also an independent predictor of groin WCs, suggesting the clinical importance of gynoid vs android fat distribution.

OBJECTIVE: Historically, edge stenosis and late thrombosis limited the effectiveness of adjunctive endovascular brachytherapy (EVBT) for in-stent restenosis (ISR) after percutaneous transluminal angioplasty (PTA) and stenting. We evaluated an updated protocol of PTA and EVBT for ISR among patients with lower extremity occlusive disease. METHODS: This is a retrospective, single-center review of patients treated with PTA and EVBT for ISR in the iliac and femoropopliteal segments between 2004 and 2012. A dose of 20 Gy was given at a depth of 0.5 mm beyond the radius of the largest PTA balloon using iridium 192, with at least 2-cm-long margins of radiation coverage proximal and distal to the injured area. Stents were assessed for patency by duplex ultrasound imaging at 1, 3, 6, 9, 12, and 18 months and then yearly. The primary end point was freedom from ≥50% restenosis in the treated segment at 6 months, 1 year, and 2 years. Patency data were estimated using the Kaplan-Meier method. Secondary end points were early and late thrombotic occlusion. RESULTS: Among 42 consecutive cases in 35 patients of EVBT for ISR in common or external iliac (9 [20.8%]) and superficial femoral or popliteal (33 [76.7%]) arteries, or both, 21 patients (50%) had claudication, asymptomatic hemodynamically significant stenoses were identified on duplex ultrasound imaging in 16 (38.1%), and 4 (9.8%) had critical limb ischemia. Mean treated length was 23.5 ± 12.3 cm over a mean duration of 16.1 ± 9.6 minutes. There was one technical failure (2.3%). Median post-EVBT follow-up time was 682 days (range, 1-2262 days). There were two (4.9%) and five (11.9%) cases of early and late thrombotic occlusions, respectively. There was one death, believed to be secondary to acute coronary syndrome. Primary, assisted primary, and secondary patency in the entire cohort was 75.2%, 89.1%, and 89.1%, respectively, at 1 year and 63.7%, 80.6%, and 85.6%, respectively, at 2 years. CONCLUSIONS: This contemporary protocol of PTA and adjunctive EVBT for lower extremity ISR, which is updated from those used in prior trials and includes a surveillance strategy that identifies at-risk stents for reintervention before occlusion, may be a promising treatment for lower extremity ISR at institutions where a close collaboration between vascular surgeons and radiation oncologists is feasible.

BACKGROUND: This study seeks to quantify variation in healthcare utilization and per capita costs using system-defined geographic regions based on enrollee residence within the Military Health System (MHS). METHODS: Data for fiscal years 2007 - 2010 were obtained from the Military Health System under a data sharing agreement with the Defense Health Agency (DHA). DHA manages all aspects of the Department of Defense Military Health System, including TRICARE. Adjusted rates were calculated for per capita costs and for two procedures with high interest to the MHS- back surgery and Cesarean sections for TRICARE Prime and Plus enrollees. Coefficients of variation (CoV) and interquartile ranges (IQR) were calculated and analyzed using residence catchment area as the geographic unit. Catchment areas anchored by a Military Treatment Facility (MTF) were compared to catchment areas not anchored by a MTF. RESULTS: Variation, as measured by CoV, was 0.37 for back surgery and 0.13 for C-sections in FY 2010- comparable to rates documented in other healthcare systems. The 2010 CoV (and average cost) for per capita costs was 0.26 ($3,479.51). Procedure rates were generally lower and CoVs higher in regions anchored by a MTF compared with regions not anchored by a MTF, based on both system-wide comparisons and comparisons of neighboring areas. CONCLUSIONS: In spite of its centrally managed system and relatively healthy beneficiaries with very robust health benefits, the MHS is not immune to unexplained variation in utilization and cost of healthcare.

BACKGROUND: Accurate risk estimation is essential when benchmarking surgical outcomes for reimbursement and engaging in shared decision-making. The greater complexity of emergency surgery patients may bias outcome comparisons between elective and emergency cases. OBJECTIVE: To test whether an established risk modelling tool, the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) predicts mortality comparably for emergency and elective cases. METHODS: From the ACS-NSQIP 2011-2012 patient user files, we selected core emergency surgical cases also common to elective scenarios (gastrointestinal, vascular, and hepato-biliary-pancreatic). After matching strategy for Common Procedure Terminology (CPT) and year, we compared the accuracy of ACS-NSQIP predicted mortality probabilities using the observed-to-expected ratio (O:E), c-statistic, and Brier score. RESULTS: In all, 56,942 emergency and 136,311 elective patients were identified as having a common CPT and year. Using a 1:1 matched sample of 37,154 emergency and elective patients, the O:E ratios generated by ACS-NSQIP models differ significantly between the emergency [O:E = 1.031; 95% confidence interval (CI) = 1.028-1.033] and elective populations (O:E = 0.79; 95% CI = 0.77-0.80, P < 0.0001) and the c-statistics differed significantly (emergency c-statistic = 0.927; 95% CI = 0.921-0.932 and elective c-statistic = 0.887; 95% CI = 0.861-0.912, P = 0.003). The Brier score, tested across a range of mortality rates, did not differ significantly for samples with mortality rates of 6.5% and 9% (eg, emergency Brier score = 0.058; 95% CI = 0.048-0.069 versus elective Brier score = 0.057; 95% CI = 0.044-0.07, P = 0.87, among 2217 patients with 6.5% mortality). When the mortality rate was low (1.7%), Brier scores differed significantly (emergency 0.034; 95% CI = 0.027-0.041 versus elective 0.016; 95% CI = 0.009-0.023, P value for difference 0.0005). CONCLUSION: ACS-NSQIP risk estimates used for benchmarking and shared decision-making appear to differ between emergency and elective populations.

OBJECTIVE: Despite patent vein bypass grafts, some patients with critical limb ischemia (CLI) receive major amputations. We analyzed the predictive factors leading to major amputation in the presence of patent lower extremity bypass (LEB) grafts. METHODS: Data from the Project of Ex-Vivo vein graft Engineering via Transfection III (PREVENT III), a large prospective randomized trial of 1404 patients who underwent LEB with vein graft for CLI, were queried for outcomes. The primary outcome was major amputation with patent (PMA) LEB compared with patients with patent LEB who achieved limb salvage (PLS). The population excluded those who received amputation for occluded grafts. A Cox proportional hazard model identified independent predictors. RESULTS: Of 1404 LEB patients, 162 (11.5%) had major amputation: 89 (6.3%) with patent and 73 (5.2%) with occluded LEB. For PMA, 21 of 89 (23.6%) developed critical stenosis and 11 of 21 (52.4%) were revised. For PLS, 460 of 1242 (37.0%) developed critical stenosis and 351 of 460 (76.3%) were revised. Predictive patient factors included having preoperative gangrene (vs rest pain; hazard ratio [HR], 3.504; 95% confidence interval [CI], 1.533-8.007; P = .0029), diabetes (HR, 1.800; 95% CI, 1.006-3.219; P = .0477), black (vs white) race (HR, 1.779; 95% CI, 1.051-3.011; P = .0321), baseline creatinine clearance <25 mL/min (vs >65 mL/min; HR, 1.759; 95% CI, 1.016-3.048; P = .0439), prior history of coronary artery bypass grafting (HR, 1.702; 95% CI, 1.080-2.683; P = .0221), and lower baseline activity quality of life score (HR, 1.401; 95% CI, 1.105-1.778; P = .0054). Postoperative wound factors included gangrenous changes (HR, 5.830; 95% CI, 1.647-20.635; P = .0063), surgical wound necrosis (HR, 5.319; 95% CI, 1.478-19.146; P = .0105), deep (vs superficial) wound infection (HR, 3.815; 95% CI, 1.220-11.927; P = .0213), and wound healing abnormally (HR, 3.754; 95% CI, 1.061-13.278; P = .0402). Associated postoperative consequences leading to PMA included having recurrent CLI symptoms (HR, 2.915; 95% CI, 1.816-4.681; P < .0001), a severe (vs mild) adverse event (HR, 2.751; 95% CI, 1.391-5.443; P = .0036), fewer percutaneous revisions (HR, 2.425; 95% CI, 1.573-3.740; P < .0001), discharge on low-molecular-weight heparin (HR, 2.087; 95% CI, 1.309-3.326; P = .0020), and decreasing days to critical stenosis/occlusion/revision/amputation (HR, 1.010; 95% CI, 1.007-1.012; P < .0001). CONCLUSIONS: Whereas a patent vein graft is important to all vascular surgeons, additional factors should be considered in trying to attain limb salvage for patients with CLI. These factors include intervening surgically before CLI has progressed to a state of gangrene or limited activity and optimizing nutrition, diabetes control, cardiac conditions, and activity level. Revision offers hope for clinical improvement but may be delayed when there is no graft lesion identified. The absence of a graft lesion to revise may also portend amputation despite a patent graft because of nongraft-related factors such as infection. Finally, the experience of a severe (vs mild) adverse event may also result in limb loss despite a patent graft. Systematic efforts to reduce severe adverse events among patients may also lead to increased limb salvage.

OBJECTIVE: In addition to traditional surgical outcomes, perioperative quality of life is being scrutinized as a patient-centric metric. As part of a prospective study in a contemporary surgical cohort, subjective health states were examined in context of postoperative wound complications (WCs). We hypothesized that WCs negatively affect quality of life. METHODS: The EuroQol (EQ)-5D subjective health state data, comprising five domains with 1 (good) to 3 (poor) ordinal scoring, plus visual analog score, were collected at the day of surgery and at 2 and 4 weeks of follow-up in a study evaluating silver-eluting dressings in 500 patients at three centers. A preference-weighted index was calculated. Groups were defined by no complication (NC) or presence of one or more postoperative WCs. RESULTS: Patients (72% male) were a mean age of 67.6 years. Primary indications included critical limb ischemia (41.4%), claudication (31.6%), and abdominal aortic aneurysm (11.2%; open groin access for endovascular aneurysm repair). At least one WC occurred in 148 patients (29.6%). Baseline demographics were similar except mean age (NC group, 67.9 years; WC group, 65.7 years; P = .042) and body mass index (NC group, 27.0 kg/m2; WC group, 28.2 kg/m2). WCs were associated with use of conduit for reconstruction (P = .002), below-knee incisions (P = .002), and incision length (P < .001). Compared with the NC group, there was a decrement in quality-of-life scores in the WC group at 2 weeks (mean change, -0.217; P = .001) but not at 4 weeks (mean change, +0.044; P = .065) postoperatively. Subgroup analysis showed quality-of-life change after WC was most significant in the claudication group (P = .008). The EQ-5D visual analog scale score was lowest in groups with rest pain (57.0) and tissue loss (55.1) and highest in the abdominal aortic aneurysm cohort (71.8). CONCLUSIONS: EQ-5D identified a significantly decreased quality-of-life score 2 weeks after WCs in a cohort undergoing elective infrainguinal arterial surgery. This effect was not present 4 weeks postoperatively.

OBJECTIVE: Major lower extremity (MLE) amputation is a common procedure that results in a profound change in a patient's life. We sought to determine the association between social support and outcomes after amputation. We hypothesized that patients with greater social support will have better post amputation outcomes. METHODS: From November 2011 to May 2013, we conducted a cross-sectional, observational, multicenter study. Social integration was measured by the social integration subset of the Short Form Craig Handicap Assessment and Reporting Technique. Systemic social support was assessed by comparing a United States and Tanzanian population. Walking function was measured using the 6-minute walk test and quality of life (QoL) was measured using the EuroQol-5D. RESULTS: We recruited 102 MLE amputees. Sixty-three patients were enrolled in the United States with a mean age of 58.0. Forty-two (67%) were male. Patients with low social integration were more likely to be unable to ambulate (no walk 39% vs slow walk 23% vs fast walk 10%; P = .01) and those with high social integration were more likely to be fast walkers (no walk 10% vs slow walk 59% vs fast walk 74%; P = .01). This relationship persisted in a multivariable analysis. Increasing social integration scores were also positively associated with increasing QoL scores in a multivariable analysis (ß, .002; standard error, 0.0008; P = .02). In comparing the United States population with the Tanzanian cohort (39 subjects), there were no differences between functional or QoL outcomes in the systemic social support analysis. CONCLUSIONS: In the United States population, increased social integration is associated with both improved function and QoL outcomes among MLE amputees. Systemic social support, as measured by comparing the United States population with a Tanzanian population, was not associated with improved function or QoL outcomes. In the United States, steps should be taken to identify and aid amputees with poor social integration.
