The cost of care for diabetic foot ulcers is estimated to be more than $1.5 billion annually. The aim of this study was to analyze inpatient diabetic foot ulcer cost changes over time and to identify factors associated with these costs. ⋯ Hospital charges and costs related to diabetic foot ulcers have increased significantly over time despite stable hospital length of stay and proportion of emergency admissions. Risk-adjusted analyses suggest that this change might be reflective of increasing charges associated with a progressively sicker patient population and attempts at limb salvage. Despite this, the overall incidence of major amputations remained stable.

Comparative Study
Comparative safety of endovascular and open surgical repair of abdominal aortic aneurysms in low-risk male patients.
The prevalence of significant comorbidities among patients with abdominal aortic aneurysms (AAAs) has contributed to widespread enthusiasm for endovascular AAA repair (EVAR). However, the advantages of EVAR in patients at low risk for open surgical repair (OSR) remain unclear. The objective of this study was to assess perioperative outcomes of EVAR and OSR in low-risk patients. ⋯ Our results demonstrate that even among those male patients at low risk for OSR on the basis of comorbidities, EVAR is associated with reduced perioperative mortality and major complications. Whereas clinical decisions must account for safety and long-term effectiveness, the short-term benefit of EVAR is evident even among male patients at the lowest risk for OSR.

Endovascular repair of peripheral arterial trauma using covered stent grafts is a minimally invasive alternative to open surgery in selected patients. Although the technical feasibility of endovascular repair has been established, there are a paucity of data regarding outcomes. The purpose of this study was to evaluate the short-term outcomes of endovascular repair in patients with peripheral arterial trauma. ⋯ The present study outlines our early experience with endovascular repair of peripheral arterial injuries in a variety of anatomic locations. Overall complication rates are appreciable but can be effectively detected and managed with additional intervention. The inclusion of endovascular modalities in algorithms of trauma care holds considerable promise. The need to better define optimal algorithms for utilization and determine long-term outcomes of intervention requires significant additional study.

Multicenter Study Observational Study
Acute kidney injury defined according to the 'Risk,' 'Injury,' 'Failure,' 'Loss,' and 'End-stage' (RIFLE) criteria after repair for a ruptured abdominal aortic aneurysm.
Acute kidney injury (AKI) is a serious complication after repair of a ruptured abdominal aortic aneurysm (RAAA). In the present Society for Vascular Surgery (SVS)/International Society for CardioVascular Surgery (ISCVS) reporting standards patients are classified as no dialysis (grade I), as temporary dialysis (grade II), and as permanent dialysis or fatal outcome (grade III). However, AKI is a broad clinical syndrome including more than the requirement for renal replacement therapy. The recently introduced 'Risk,' 'Injury,' 'Failure,' 'Loss,' and 'End-stage' (RIFLE) classification for AKI comprises three severity categories based on serum creatinine and urine output ('Risk,' 'Injury,' and 'Failure'). The objective of the present study was to assess the incidence of AKI using the RIFLE criteria (AKIRIFLE). Secondary objectives were to assess the incidence of AKI as defined using the SVS/ISCVS reporting standards (AKISVS/ISCVS) and the association between AKIRIFLE and death. ⋯ The incidence of AKI defined according to the RIFLE criteria (74%) was greater than defined using the SVS/ISCVS reporting standards (48%) and patients categorized as 'Failure' using the RIFLE criteria had a greater risk of dying than patients without AKI. These results indicate that the problem of AKI is much bigger than previously anticipated and that minimizing injury to the kidney could be an important focus of future research on reducing the death rate after RAAA repair.

Multicenter Study Observational Study
Factors associated with surgical site infection after lower extremity bypass in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI).
Surgical site infection (SSI) is a major source of morbidity after infrainguinal lower extremity bypass (LEB). This study examines processes of care associated with in-hospital SSI after LEB and identifies factors that could potentially be modified to improve outcomes. ⋯ In-hospital SSI after LEB varies substantially across VQI hospitals. Three modifiable processes of care (transfusion rate, procedure time, and type of skin preparation) were identified and may be used by hospitals to reduce SSI rates. This study demonstrates the value of the SVS VQI detailed shared clinical registry to identify improvement opportunities directly pertinent to providers that are not available in typical administrative data sets.
