General Surgery Residents Competence and Autonomy in Core Vascular Surgery Procedures

As vascular surgery has become increasingly sub-specialized, the scope of vascular care that general surgeons can be trained to provide has come into question. Thus, we sought to understand the competence and autonomy of general surgery residents (GSR) in core vascular surgery procedures.

Three core operations in vascular surgery were identified: lower extremity (LE) amputations, arteriovenous fistula (AVF) creation, and LE embolectomy and thrombectomy (thromboembolectomy). Assessment of GSRs autonomy and performance for these operations were obtained from the System for Improving and Measuring Procedural Learning (SIMPL) application from 2018 to 2022. Data were analyzed using a combination of descriptive statics and chi-square tests. Logistic generalized linear mixed models (GLMM) were also performed.

1950 SIMPL operative assessments were analyzed. Senior residents were found to be meaningfully autonomous and competent in 82% (n = 237) and 66% (n = 189) of LE amputation assessments and 50% (n = 225) and 32% (n = 142) of AVF assessments, respectively. The majority of senior residents failed to achieve meaningful autonomy (n = 99, 67%) and competence (n = 116, 80%) for LE thromboembolectomy cases, while the majority of junior and midlevel residents failed to achieve meaningful autonomy and competence for all 3 procedures. For an average case, a senior resident had an 86% (95% CI: 79% - 89%) chance of achieving competence during LE amputation, 41% (95% CI: 43% - 62%) chance during AVF, and 21% (95% CI: 27% - 52%) chance during LE thromboembolectomy.

In this study, GSR failed to achieve competence and meaningful autonomy for 3 core procedures, including AVF creation. Notably, the creation of an AVF was recently included within the new Entrustable Professional Activities (EPAs) for general surgery. However, the results of this study suggest that GSR will fail to demonstrate the competence needed for entrustment. Training requirements for general surgery residents in vascular surgery may need to be reassessed.
