Low-Titer O-Positive Whole Blood: Lessons From the Battlefield for Civilian Rural Hospitals.

Low-titer O-positive whole blood was used extensively by the military during operations in Iraq and Afghanistan. Studies have consistently shown that this therapy is feasible, safe, and effective in the management of hemorrhagic shock in trauma patients, and it is now the standard of care across the US military Joint Trauma System. The military's success in using low-titer O-positive whole blood has renewed the practice in the civilian setting, with recent research confirming its safety and efficacy. In a few short years, use of this treatment for hemorrhagic shock has expanded to more than 80 US level I and level II trauma centers. However, its use is still relatively rare in the rural hospital setting. This article describes the benefits for patients, staff members, and the overall trauma system of using low-titer O-positive whole blood in rural hospitals.
