Declining IVC filter use in trauma patients raises flags

IVC filter placement in trauma patients is declining but shows wide variation among hospitals, affecting patient outcomes.

Among 2.3 million trauma patients, only 0.81% had IVC filters placed, down from 1.15% in 2017 to 0.59% in 2024 (p<0.001).
22.5% of centers had insertion rates ≥1%, highlighting significant interhospital differences.

Higher IVC filter use did not improve in-hospital mortality but increased DVT, PE, and VTE rates (all p<0.001).

An opportunity exists to refine guidelines and ensure appropriate filter use across trauma centers.
