Abstract: Objective　To investigate the efficacies of red blood cell and platelet transfusion for adult patients and its influencing factors, and to improve the efficiency of blood transfusion therapy. Methods　The data of the patients who received red blood cell and platelet transfusion in The 73rd Group Military Hospital of the Chinese People's Liberation Army Ground Force from July 2019 to June 2021 were retrospectively analyzed, and the efficacies of red blood cell and platelet transfusion were evaluated. The patients were divided into groups according to their gender, age, frequency of blood transfusion, and underlying diseases, and the influencing factors of red blood cell and platelet transfusion efficacies were investigated. The χ² test was applied. Results　A total of 282 patients taking red blood cell transfusion therapy, including 136 males and 146 females who were 18-82 years old, and 98 patients taking platelet transfusion therapy, including 46 males and 52 females who were 18-88 years old, were included in this study. According to data analysis, the total effective rate of red blood cell transfusion for the 282 patients was 81.91% (231/282), and the total effective rate of platelet transfusion for the 98 patients was 85.71% (84/98). According to the chi-square test, the effective rates of red blood cell and platelet transfusions in the 18-60 years old patients were higher than those in the ≥60 years old patients (χ²_{red blood cells}=7.415, P_{red blood cells}=0.006; χ²_platelet=4.961, P_platelet=0.026). The effective rates of red blood cell and platelet transfusion in the patients with the frequency of blood transfusions <3 were higher than those in the patients with the frequency of blood transfusions ≥3 (χ²_{red blood cells}=7.760, P_{red blood cells}=0.005; χ²_platelet=6.853, P_platelet=0.009). The effective rates of red blood cell and platelet transfusion in the patients with acute blood loss disease and hematopoietic dysfunction disease were higher than those in the patients with chronic blood loss disease (χ²_{red blood cells}=18.653, P_{red blood cells}<0.001; χ²_platelet=10.597, P_platelet=0.005). The effective rate of platelet transfusion in the patients with fever was lower than that in the patients with normal body temperature (χ²_platelet=8.459, P_platelet=0.004). The effective rates of red blood cell and platelet transfusion in the patients taking surgery were lower than those in the patients taking no surgery (χ²_{red blood cells} = 9.928, P_{red blood cells} = 0.002; χ²_platelet = 5.878, P_platelet = 0.015). Conclusions　The effective rates of redblood cell and platelet transfusion for adult patients in The 73rd Group Military Hospital of the Chinese People's Liberation Army Ground Force are relatively high. The efficacies of redblood cell and platelet transfusion are related to the patients' age, frequency of blood transfusion, and underlying diseases. Clinical attention should be paid to the patients' blood transfusion treatment.
