Abstract: Objective To investigate the production of red blood cell products in 20 blood stations in China, and therefore provide data support for improving their productivity. Methods The relevant data of red blood cell production in 20 blood stations in China were collected from 2017 to 2021, and the data of whole blood collection, blood collection efficiency, blood scrap rate of red blood cell components, utilization efficiency of red blood cell inventory, and productivity of red blood cell products were statistically analyzed. Results The whole blood collection volume of 20 blood stations increased by an average of 4.38% annually from 2017 to 2021, the blood collection efficiency was 96%, the scrap rate of red blood cell components was 1.51%, utilization efficiency of red blood cell inventory was 97.79%, and the productivity of red blood cell product was 96.92%. Conclusion The productivity of red blood cell products is high, but the influencing factors vary greatly in regions. Blood stations should carefully analyze the reasons and take effective measures to improve their productivity.
