Objectives: To assess the association between mortality and the day of elective surgical procedure.
Design: Retrospective analysis of national hospital administrative data.
Setting: All acute and specialist English hospitals carrying out elective surgery over three financial years, from 2008-09 to 2010-11.
Participants: Patients undergoing elective surgery in English public hospitals.
Main Outcome Measure: Death in or out of hospital within 30 days of the procedure.
Results: There were 27,582 deaths within 30 days after 4,133,346 inpatient admissions for elective operating room procedures (overall crude mortality rate 6.7 per 1000). The number of weekday and weekend procedures decreased over the three years (by 4.5% and 26.8%, respectively). The adjusted odds of death were 44% and 82% higher, respectively, if the procedures were carried out on Friday (odds ratio 1.44, 95% confidence interval 1.39 to 1.50) or a weekend (1.82, 1.71 to 1.94) compared with Monday.
Conclusions: The study suggests a higher risk of death for patients who have elective surgical procedures carried out later in the working week and at the weekend.

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.

Background: Frailty is a predictor of morbidity and mortality in older patients. This study aimed to investigate the influence of frailty status on likelihood, rate, duration, and severity of intraoperative hypotension (IOH), which can lead to severe organ dysfunction.
Methods: Surgical patients (≥70 yr old) with preoperative frailty assessment were analysed retrospectively.

Objectives: This study assessed the association between chronic obstructive pulmonary disease (COPD) severity and postoperative mortality among patients undergoing thoracic endovascular aortic repair (TEVAR) and complex endovascular aortic repair (CEVAR).
Methods: A retrospective review of the Vascular Quality Initiative database identified elective TEVAR and CEVAR cases from 2013-2022 with endograft proximal landing zone ≥2 for thoracic or complex abdominal aortic disease. Symptomatic disease, ruptures, and urgent/emergent surgeries were excluded.

Objectives: Optimal timing for intervention for abdominal aortic aneurysms remains unclear. Given the increased rupture risk with larger aneurysms, timely intervention is critical. This study sought to examine endovascular aortic aneurysm repairs (EVAR) delays across Canadian centers, focusing on potential differences related to geography, sex and race.
