Removing the barriers to prehospital blood: a roadmap to success.

This review describes the necessity, evolution, and current state of prehospital blood programs in the United States. Less than 1% of 9-1-1 Ground Emergency Medical Service agencies have been able to successfully implement prehospital blood transfusions as part of a resuscitation strategy for patients in hemorrhagic shock despite estimates that annually between 54,000 and 900,000 patients may benefit from its use. The use of prehospital blood transfusions as a tool for managing hemorrhagic shock has barriers to overcome to ensure it becomes widely available to patients throughout the United States. Barriers include 1) current state Emergency Medical Services clinicians' scope of practice limitations, 2) program costs and reimbursement of blood products, 3) no centralized data collection process for prehospital hemorrhagic shock and patient outcomes, 4) collaboration between prehospital agencies, blood suppliers, and hospital clinicians and transfusion service activities. The following paper identifies barriers and a proposed roadmap to reduce death due to prehospital hemorrhage.
