North American lower-extremity revascularization and amputation during COVID-19: Observations from the Vascular Quality Initiative.

ABSTRACT:

Introduction

The coronavirus disease 2019 (COVID-19) pandemic's impact on vascular procedural volumes and outcomes has not been fully characterized.

Methods

Volume and outcome data before (1/2019 - 2/2020), during (3/2020 - 4/2020), and following (5/2020 - 6/2020) the initial pandemic surge were obtained from the Vascular Quality Initiative (VQI). Volume changes were determined using interrupted Poisson time series regression. Adjusted mortality was estimated using multivariable logistic regression.

Results

The final cohort comprised 57,181 patients from 147 US and Canadian sites. Overall procedure volumes fell 35.2% (95% CI 31.9%, 38.4%, p < 0.001) during and 19.8% (95% CI 16.8%, 22.9%, p < 0.001) following the surge, compared with presurge months. Proc
