We modeled deployment to 10% (approximately 4200) and 50% (approximately 21,000) of U.S. EMS stations. Low\u2010titer group O whole blood (LTOWB) and liquid plasma (LP) were evaluated separately. Outcomes included units shipped to EMS, units rotated to hospitals, total units collected, discard with and without hospital rotation, LTOWB donor requirements, and annual product costs.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Implementation required approximately 148,000\u2013220,000 units annually at 10% deployment and 741,000 to 1.1\u2009million at 50%, representing an 8%\u201324% increase over current U.S. whole\u2010blood collections. LTOWB was the principal constraint, requiring about 110,000 new donors at 10% deployment and up to 550,000 at 50%. LP demand could be met through redistribution from existing collections without new donor recruitment. Hospital rotation substantially reduced discard. At 50% deployment, annual costs exceeded $540\u2009million for LTOWB versus approximately $47\u2009million for LP.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n National\u2010scale prehospital transfusion will require coordinated EMS\u2010hospital rotation, major donor recruitment for LTOWB, and targeted investment. A hybrid LTOWB\u2010LP strategy may provide the most feasible path to broader implementation.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/trf.70325","type":"journal-article","created":{"date-parts":[[2026,7,18]],"date-time":"2026-07-18T08:32:06Z","timestamp":1784363526000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Scaling of prehospital blood: A model describing impact on U.S. blood donors, distribution and cost"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5313-0376","authenticated-orcid":false,"given":"Pampee P.","family":"Young","sequence":"first","affiliation":[{"name":"American Red Cross Blood Services, Biomedical Services Washington DC USA"},{"name":"Department of Pathology, Microbiology, and Immunology Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Wood","sequence":"additional","affiliation":[{"name":"American Red Cross Blood Services, Biomedical Services Washington DC USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8312-9157","authenticated-orcid":false,"given":"John B.","family":"Holcomb","sequence":"additional","affiliation":[{"name":"Division of Acute Care Surgery, Department of Surgery University of Alabama at Birmingham Birmingham Alabama USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald H.","family":"Jenkins","sequence":"additional","affiliation":[{"name":"Department of Surgery University of Texas Health Science Center in San Antonio San Antonio Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8144-3281","authenticated-orcid":false,"given":"Matthew J.","family":"Levy","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine and Surgery Johns Hopkins School of Medicine Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,18]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"Centers for Disease Control and Prevention (CDC).Injuries and violence are leading causes of death [monograph on the internet].2021.
