Missions were included when PRBCs were administered by, or at the direction of, an LFM doctor. Primary missions and interfacility transfers (IFT) were analysed and compared with the overall mission cohort. Collected variables included transport platform, indication for transfusion, patient demographics, blood product utilisation, wastage, and compliance with adjunctive therapies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 7791 missions, PRBCs were administered on 226 missions (2.9% of all missions), including 100 primary missions (7.6% of all primary missions) and 126 IFT's (1.9% of all IFT's). A total of 492\u2009units were transfused, with 3.0% wastage. Primary trauma accounted for 59% of transfusions and medical\/surgical causes for 41%, most commonly upper gastrointestinal bleeding. Rotary\u2010wing and road\u2010based platforms demonstrated the highest transfusion incidence. No significant age differences were identified between transfused and non\u2010transfused patients. Compliance with blood warming, tranexamic acid, and calcium administration was high at 81%, 83%, and 85%, respectively. Use of O\u2010positive blood in females under 50\u2009years was rare, occurring in 0.3% of primary missions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PRBC transfusion within LFM is infrequent but essential across all missions.
