Prevention

Consider vena caval filters in trauma patients with multiple injuries ^c

Why?

• Filters reduce pulmonary embolism and death ^c

Vena caval filters reduce pulmonary embolism in multiple trauma patients

Patient	Treatment	Comparison	Outcome	CER	RRR (95% CI)	NNT (95% CI)
multiple trauma c	vena caval filter	no vena caval filter	pulmonary embolism at at discharge	18%	87% (27% to 100%)	4 (2 to 12)
			death from PE at at discharge	10%	100%	10 (6 to 29)
			death at at discharge	16%	69% (-30% to 93%)	9 (5 to 140)

Note:

• In uncomplicated DVT, vena caval filters produce no benefit ^a
