Map details prehospital blood transfusions following motor vehicle crashes in 2025

A map released by the Department of Transportation features data showing that 32,992 motor vehicle crash patients in the U.S. met the clinical criteria for prehospital blood transfusions in 2025. The incidents occurred across 3,061 counties, averaging 10.8 responses per county, according to the National Emergency Medical Services Information System. According to the Prehospital Blood Transfusion Coalition, “Exsanguination remains the leading cause of preventable deaths among victims of trauma with nearly half of these patients dying in the prehospital setting … Individuals requiring critical care in the field in many locations in the US do not have access to prehospital blood transfusions due to reimbursement policies and scope of practice limitations.”
