Multicenter Study
Variation in center-level frailty burden and the impact of frailty on long-term survival in patients undergoing elective repair for abdominal aortic aneurysms.
Frailty is increasingly recognized as a key determinant in predicting postoperative outcomes. Centers that see more frail patients may not be captured in risk adjustment, potentially accounting for poorer outcomes in hospital comparisons. We aimed to (1) determine the effect of frailty on long-term mortality in patients undergoing elective abdominal aortic aneurysm (AAA) repair and (2) evaluate the variability in frailty burden among centers in the Vascular Quality Initiative (VQI) database. ⋯ There is considerable variability of preoperative frailty among VQI centers performing elective AAA repair. Adjusting for center-level variation, frailty but not procedure type had a significant association with long-term mortality; however, frailty and procedure type were both associated with nonhome discharge. Routine measurement of frailty preoperatively by centers to identify high-risk patients may help mitigate procedural and long-term outcomes and improve shared decision-making regarding AAA repair.

Multicenter Study
Perioperative blood transfusion in anemic patients undergoing elective endovascular abdominal aneurysm repair.
Although blood transfusion can be lifesaving in active hemorrhage or severe anemia, it is also associated with increased morbidity and mortality. Several trials have established this risk and therefore defined a restrictive standard for transfusion, but this threshold and the risk of transfusions have not been specifically examined in vascular surgery patients. We therefore sought to assess transfusion practices and outcomes of anemic patients undergoing elective endovascular aneurysm repair (EVAR). ⋯ Among anemic patients undergoing elective EVAR, transfusion is associated with an increased risk of death and in-hospital complications, even after controlling for patients' comorbidities and operative factors. These data suggest that the restrictive use of blood transfusions might be safer in vascular surgery EVAR patients. Medical management of anemia may be warranted in these patients to reduce morbidity and mortality; however, further studies are needed to evaluate effectiveness.
