Integrated vascular training may not prepare graduates to care for vascular trauma patients

Vascular surgery board eligibility may be secured through 5+0 integrated programs (IV) as well as 5+2 general surgery/vascular fellowship pathway (VF). We hypothesized that IV graduates accrue less experience relevant to vascular trauma than VF graduates. We assessed the first decade of IV graduate experience and compared it to contemporaneous VF graduates.

The 2013-2022 Accreditation Council for Graduate Medical Education case log data were collected for IV and VF graduates. Vascular fellows' data were combined with synchronousgeneral surgery residency data. Open vascular cases were classed as cerebrovascular, upper extremity, thoracic, abdominopelvic, infrainguinal, and infrapopliteal. Nonvascular open cases were categorized as neck, thoracic, and abdominopelvic. Nonoperative trauma and critical care data were recorded.

There were 1,224 VF and 397 IV graduates. In 2012, 8.3% of graduating vascular surgeons trained in IV programs. By 2022, this proportion was 32.6%. The number of IV programs increased by 4.4 programs per year over the study period ( p < 0.05), whereas VF programs remained unchanged. Integrated vascular chiefs logged significantly more lower extremity cases, and VFs logged more upper extremity cases ( p < 0.05). IV graduates reported a fraction of the VF open nonvascular cases. Integrated vascular graduates logged 5% of the abdominopelvic, 18% of the thoracic, and 3% of the neck cases of VFs ( p < 0.05). Vascular fellows' critical care and nonoperative trauma were each higher than those of IV fellows ( p < 0.05). Integrated vascular graduates logged six vascular repairs for every vascular exposure.

The proportion of vascular surgeons trained through IV programs has nearly quadrupled. Integrated vascular graduates have a fraction of the experience in critical care, trauma, and nonvascular surgery compared with VF graduates. Relative inexperience with open surgical anatomy and with critically ill patients may limit IV graduates' ability to care for the patient with vascular trauma.
