Abstract: Objective To analyze the quality control indexes of national clinical blood use in 2020 and provide reference for the management of clinical blood use. Methods A retrospective investigation was carried out to collect and analyze the data of blood quality control indexes of medical institutions in 2020. Results We collected 438 clinical blood quality control data, 1 673 (68.62%) of which were from tertiary hospitals, 594 (24.37%) from secondary hospital, and 171 (7.01%) from the hospitals below secondary or other ungraded ones. There were significant differences in clinical blood quality control indexes such as the number of professional and technical personnel for blood transfusion per thousand units, reported cases of adverse transfusion reactions per thousand transfusion times, average blood consumption of third and fourth level operating tables, and average blood consumption of discharged patients among hospitals at all levels (P<0.05). Except for the indoor quality control rate of transfusion compatibility test items and the autotransfusion rate of surgical patients, the other quality control index data had significant differences between regions (P<0.05). Conclusion The quality control indexes of blood for clinical use vary in different grades of hospitals and in different regions, suggesting that there is still room for improvement in the management of blood for clinical use.
