Development of a Prehospital Tranexamic Acid Administration Protocol.

Objective: Early administration of tranexamic acid (TXA) has been shown to reduce all-cause mortality and death secondary to trauma. Our objective was to develop a collaborative prehospital TXA administration protocol between a ground EMS and academic medical center.

Methods: Physicians, pharmacists, and EMS and fire department personnel developed a prehospital TXA administration protocol between a local fire and EMS center with a Midwest tertiary care health system based on results from the CRASH-2 Trial. The protocol was initiated March 27, 2013 and the first dose of TXA was administered in September 2013.

Results: Since September 2013, nineteen trauma patients received TXA. Survival rate was 89% (17/19); 2 patients expired immediately following arrival to the trauma bay. Seven patients did not receive the in-hospital maintenance dose due to the following: 3/7 (43%) due to miscommunication of pre-TXA administration; 2/7 (29%) did not meet inclusion criteria for TXA protocol; 1/7 (14%) due to protocol noncompliance; 1/7 (14%) due to a chaotic situation with an unstable patient.

Conclusions: Prehospital TXA protocol based on the CRASH-2 trial is safe and feasible. The first dose of TXA administered under this protocol marks the first ground EMS administration in the USA. Conceivably, this will pose as a model to other trauma centers that receive patients from outlying areas without immediate access to care. Large multi-institutional analyses need to be performed to evaluate survival benefits of prehospital TXA administration protocol.
