Abstract Blood transfusion is an important treatment for patients with major burns. Understanding the predictive factors of blood product usage in major burns can improve effective transfusion therapy. We retrospectively reviewed the medical records of the Burn Center, First Affiliated Hospital of the Chinese Naval Military Medical University, from August 2009 to July 2019 and enrolled all patients with major burns treated in that decade. Basic information, condition, and blood-transfusion details of the patients were analyzed to identify predictive factors for blood use and prognosis. Despite a yearly decreasing trend, the frequency of use of blood-product usage in major burns was high at 57.72%, with 5.39 times and 28.76 units of blood usage per person. Burn area was the most important predictive factor for blood transfusion at different stages. Burn depth, combined with injury, age, and other factors, affected blood use. Blood use or volume correlated with prognosis; especially, platelet and cryoprecipitate use was significantly associated with increased mortality. Blood product usage in major burns patients is related not only to the clinical condition, but also to doctors' experience, which can predict prognosis. Blood use is associated with increased mortality, although there was no evidence of a causal association.
