Blood Components Consumption Model in China: A Single-center Investigation with-in 11-years Interval

Xiaoshuang Wu, Jiajia Xin, Yaozhen Chen, Wenting Wang, Xingbin Hu, Wen Yin

Background: With the global demand increasing in blood transfusion, and the advancing of medical technology, transfusion safety and efficacy are great challenge all over the world. However, because of lagging information technologies, transfusion consumption in certain hospital and analysis in developing nations are invalid and inaccuracy, thus constrained further progress in transfusion medicine in these countries.

Methods and Findings: We respectively recorded the actual consumption amounts of red blood cells (RBC), plasma, platelets, and cryoprecipitate were collected in Xijing Hospital from 2003 to 2013. Then, we developed our consumption predict model (CPM) to estimate the needs of RBC, plasma, PLT, cryoprecipitate in 2014. Last, for testing our CPM capability, we compared the predicted volume with the actual consumption amounts of blood transfusion. After a long period of increasing, the red blood cell usage decreased from 2012 in this hospital. With a 19% decrease compared with that of in 2013, the total utilization of red blood cell is 11271800 ml in 2014, Plasma usage almost maintained stable dnuring the past years, and this trend seemed will continue. However, platelet and cryoprecipitate consumption were opposite to RBCs or platelets. Inconceivably, compared with platelet’s annual growth rate of 22%, cryoprecipitate annual growth was 58%. The demand for blood components over an 11-year interval is representative and indicative for the administration of blood components consumption in one of the most large scale hospital in China.

Conclusions: Our CPM represented a basis for developing a standard blood management strategy, and allowing blood transfusion services in being better prepared for future consumption requirements.
