The effect of participation of interventional radiology team in a primary trauma survey on patient outcome

•Participation of interventional radiologists in primary trauma surveys shortens time to hemostasis. Consequently, patients with hemodynamically unstable trauma survive better.•Patients with hemodynamically unstable trauma have a survival rate 24.6% greater than the predictive survival rate via participation of interventional radiologists.•Median intervention initiation and procedure times in patients with hemodynamically unstable trauma are 54 and 48 min, respectively and shorter than those with hemodynamically stable trauma.
