In this episode of EMS One-Stop, host Rob Lawrence is joined by Dr. Christine Carico and Dr. Matt Levy to discuss the peer-reviewed paper, “Nationwide Trends in Prehospital Blood Product Use After Injury.” The paper, published in “Transfusion” in April 2025, explores the use of blood products in prehospital trauma care.

Despite the proven benefits of blood transfusion in the field, their research uncovers the alarming reality that less than 1% of eligible patients receive prehospital blood products. This conversation dives into the study’s methodology, key findings and the significant barriers EMS systems face in implementing blood transfusion protocols. The discussion also touches on the evolving role of EMS in trauma care, regional variations in blood product access, and the future of prehospital blood transfusion programs.

Dr. Carico and Dr. Levy break down their work and reflect on the data, explaining how the study used National Emergency Medical Services Information System (NEMSIS) data to identify trauma patients who would have benefited from blood transfusions.

The episode delves into the operational challenges EMS systems face in obtaining and administering blood products in the field, the financial and logistical obstacles, and the potential life-saving impact of more widespread adoption of these protocols.
