Intraoperative workload in elective open vascular and endovascular surgery: A study of procedural drivers

Abstract

This study investigated vascular surgeon workload and its association with specific procedural drivers over different procedure types. Thirteen attending vascular surgeons (two females) were emailed a survey over a 3-month period. Data from 253 surgical procedures (118 open, 85 endovascular, 18 hybrid, and 32 venous) revealed high physical and cognitive workload among vascular surgeons. Based on the statistically significant findings and similar non-significant trends in the data (significance level of 0.01), open and hybrid vascular procedures showed higher levels of physical and cognitive workload compared to venous cases, while endovascular procedures were relatively more moderate. Additionally, the workload subscales for five subcategories of open procedures (e.g., arteriovenous access) as well as three subcategories of endovascular procedures (e.g., aortic) were compared. The granularity of the intraoperative workload drivers across various vascular procedure types and adjunct equipment could be the key to create targeted ergonomic interventions to reduce workload during vascular surgeries.
