Fifteen-Year Trend in Inferior Vena Cava Filter Utilization before and after U.S. Food and Drug Administration Communications: Data from the National Inpatient Sample 2005-2019.

ABSTRACT

The purpose of this study was to evaluate the contemporary trends in inferior vena cava (IVC) filter utilization in the inpatient setting following the U.S. Food and Drug Administration (FDA) safety communications and compare those trends in relation to incidence of hospital admissions involving venous thromboembolism (VTE). The National Inpatient Sample was queried between 2005 and 2019. There was an increasing trend in the utilization of IVC filters between 2005 and 2010 (P < .01). Following the FDA communication in 2010, this reversed to a decreasing trend (P < .001), which persisted following the second FDA communication in 2014, although there was no significant change in the rate of decline (P = .67). Throughout the study period, the proportion of IVC filters placed in patients with VTE increased from 70.8% to 82.2%.
