The Sustained Impact of the COVID-19 Pandemic on Vascular Surgical Care Delivery

Background: The COVID-19 pandemic necessitated postponement of vascular surgery procedures nationally. Whether procedure volumes have since recovered remains undefined. Therefore, our objective was to quantify changes in procedure volumes and determine whether surgical volume has returned to its prepandemic baseline. Methods: This study was a retrospective cross-sectional study between 2018 and 2023 using the ect. We studied patients who underwent 1 of 3 procedures: abdominal aortic aneurysm (AAA) repair for intact aneurysms, carotid endarterectomy (CEA), and major lower extremity amputation (LEA). The case volume of each quarter of 2020-2023 was compared to its corresponding prepandemic quarter in 2019. We then performed a subanalysis of these trends by sex, age, and race. Results: We identified 21,031 procedures: 4,411 AAA repair, 8,361 CEA, and 8,259 LEA. The average percent change during the baseline prepandemic period from 2018 to 2019 was -4.3% for AAA repair, -8.5% for CEA, and -2.6% for LEA. Compared to Q2 of 2019, Q2 of 2020 demonstrated that AAA repair procedures decreased by 47%, CEA by 40%, and LEA by 14%. While procedures initially rebounded in Q3 of 2020, volumes did not return to their prepandemic baseline, demonstrating a persistent volume reduction (-16% AAA, -22% CEA, and -11% LEA). Thereafter, procedure counts again declined in Q1 of 2022 (-25% AAA, -34% CEA, and -25% LEA). Conclusions: Despite a perception that vascular surgical care was singularly disrupted at the outset of the pandemic, there has been a sustained reduction in vascular surgical volume since 2019. Not only have procedure volumes not returned to prepandemic baseline but it also appears that there has been a cumulative incremental impact on overall procedure volume. The impact of these findings on long-term population health remains uncertain and necessitates a better understanding of postpandemic care delivery.
