Patient and operational factors that influence the decision to place an inferior vena cava filter in a pulmonary embolism response team.

Objective: The use of inferior vena cava (IVC) filters is controversial. However, the procedure is widely performed for secondary prophylaxis in patients with severe pulmonary embolism (PE), including those treated by a PE response team (PERT). In this study, we analyzed patient factors associated with the clinical decision to place an IVC filter in PERT patients.
