Abstract: Objective To provide the basis for management and deployment of blood resources through retrospective analysis of clinical blood transfusion in the hospital. Methods Shanghai Kingstar blood transfusion management software was used to collect data of the clinical blood usage in clinical departments in 2015-2016，including component transfusion rate，component transfusion ratio and quarterly volume of blood consumption. Results The component transfusion frequenciesa were 99.72% and 99.80% respectively，and the blood transfusion mostly occurred in the fourth quarter of the year. The surgical ICU had the most consumption whereas the departments of gastroenterology and heptology used the large portion of RBCs and plasma. The RBCs transfusion decreased by a maximum of 40.63% in orthopedics due to the autologous blood transfusion. Conclusion Regular retrospective analysis of clinical transfusion is conducive to monitoring clinical blood uses and drawing up blood storage plan . Autologous blood transfusion is of great significance in saving blood resources.
