Understanding the Scope of Acute Care Vascular Surgery at a Tertiary Academic Medical System

The restructuring of nonelective general surgery and nationwide implementation of the acute care surgery paradigm has improved patient outcomes and healthcare resource utilization. Although vascular surgery maintains one of the highest acuity rates among surgical specialties, the acute care vascular surgery (ACVS) practice model has not been widely accepted. In the present study, we investigate the scope and burden of ACVS at a tertiary academic medical system. All vascular surgical procedures performed at three hospitals comprising a large tertiary academic medical system were retrospectively queried through electronic medical records. Data were collected on procedure, acuity, timing of intervention, primary service, admission type, and total costs and charges. Patients were stratified by acuity of surgical intervention, with ACVS being defined as urgent or emergent operation. A total of 12,689 vascular surgeries were performed from 2018 to 2022. ACVS procedures comprised 22.1% of this total (n = 2,803; 12.5% urgent, 9.6% emergent), with an annual burden ranging from 19.1% to 28.3%. Vascular surgeons served as primary surgeon in 91.3% of ACVS and cosurgeon in 8.7%. Fourteen separate surgical specialties requested acute vascular assistance, with the most frequently consulting specialties, including trauma or acute care surgery (ACS) (n = 109, 3.9%) and cardiac surgery (n = 74, 2.6%). ACVS cases were more frequently performed during after-hours (30.7% vs 11.6%) and on weekends (27.1% vs 2.0%) compared with elective vascular procedures (P
