Frailty has been increasingly used as a prognostic indicator for various surgical operations. Patients with peripheral arterial disease represent a cohort of population with advanced medical comorbidities. The aim of this study is to correlate the postoperative outcomes after lower extremity bypass surgery with preoperative modified frailty index (mFI). ⋯ This study demonstrates that the mFI can be used as a valuable tool to identify patients at a higher risk for developing postoperative complications after lower extremity revascularization. For patients with mFI score of 0.54-0.63, the risk of mortality and complications increases significantly. mFI can be used as a useful screening tool to identify patients who are at a high risk for developing complications.

Comparative Study
External Validation of a Rapid Ruptured Abdominal Aortic Aneurysm Score.
The Rapid Ruptured Abdominal Aortic Aneurysm Score (RrAAAS) was developed from Vascular Study Group of New England (VSGNE) data (649 ruptured abdominal aortic aneurysm (rAAA) patients, repaired both open and endovascularly), using preoperative age, creatinine, and blood pressure. This study validates that model using the larger National Vascular Quality Initiative (VQI) data set and compares its performance to previous models. ⋯ The previously described RrAAAS has similar discrimination as the GAS and ERAS, is easier to obtain in an emergency setting, and has been recalibrated to reflect the experience of a large national sample. The RrAAAS could be useful for clinicians caring for these patients and could be used for risk adjustment when comparing regional differences in mortality associated with rAAA repair.

Comparative Study
Analysis of Patients Undergoing Major Lower Extremity Amputation in the Vascular Quality Initiative.
Despite an aggressive climate of limb salvage and revascularization, 7% of patients with peripheral artery disease undergo major lower extremity amputation (LEA). The purpose of this study was to describe the current demographics and early outcomes of patients undergoing major LEA in the Vascular Quality Initiative (VQI). ⋯ In the VQI registry, major LEA was performed predominantly for ischemic rest pain and tissue loss with a BKA:AKA ratio of 1.29:1. Patients undergoing AKA versus BKA were older, had lower ABI, lower rates of 30-day postoperative complications but higher rates of 30-day mortality. This registry offers an important real-world resource for studies pertaining to vascular surgery patients undergoing major lower extremity amputation.

In January 2015, we created a multidisciplinary Aortic Center with the collaboration of Vascular Surgery, Cardiac Surgery, Interventional Radiology, Anesthesia and Hospital Administration. We report the initial success of creating a Comprehensive Aortic Center. ⋯ Designation as a comprehensive Aortic Center with implementation of strategic workflow systems and a culture of "no refusal of transfers" resulted in a significant increase in aortic volume for both emergent and elective aortic cases. Case volumes increased for all specialties involved in the center. Improvements in transfer center and emergency medical services communication demonstrated a trend toward more efficient transfer times. These increases and improvements were sustainable for 2 years after this designation.

As high healthcare costs are increasing scrutinized, a movement toward reducing patient hospital admissions and lengths of stay has emerged, particularly for operations that may be performed safely in the outpatient setting. Our aim is to describe recent temporal trends in the proportion of dialysis access procedures performed on an inpatient versus outpatient basis and to determine the effects of these changes on perioperative morbidity and mortality. ⋯ Dialysis access operations are increasingly being performed on an outpatient basis, with stable perioperative outcomes. Inpatient procedures are associated with worse outcomes, likely because they are reserved for patients with acute illnesses, serious comorbidities, and poor functional status. Overall, for appropriately selected patients, the movement toward performing more elective dialysis access operations on an outpatient basis is associated with acceptable outcomes.
