Due to excessive clinical blood usage and a rapidly aging population, an impending blood shortage in Taiwan is inevitable. This study aimed to determine the potential blood deficit in Taiwan in 2030. The numbers of units of whole blood (WB) donated and red blood cells (RBC) transfused will increase from 1,182,973 to 1,115,803 in 2018 to 1,230,500 and 1,250,760 in 2030, respectively. Considering the gap between donation and transfusion, we estimate a deficit of 97,633 units of WB in 2030. Blood collection will increasingly rely on donors over the age of 40. Moreover, we observed a large decline in units of WB donated among people less than 25 years old. A growing demand for RBC is attributed to the aging population and limited decreases in age-specific units of RBC transfused per capita. Scrutinizing and forecasting changes in blood collection and transfusion are necessary for generating strategies to mitigate blood shortages. [ABSTRACT FROM AUTHOR]

Recent blood distribution profiles for transfusions in Taiwan have not been comprehensively documented. This study aimed to analyze trends in red blood cell (RBC), platelet, and plasma distribution rates, and compares these profiles with those in other countries. The distribution rates of RBC, platelets, and plasma in Taiwan during 2015 were 47.6, 11.1, and 26.8 units per 1000 population, respectively. At least 1.5 and 2.5-fold higher platelet and plasma distribution rates were observed than other selected countries. During 2007-2015, there was no significant change in RBC distribution. However, we observed a significant increase of 0.20 (95% CI: 0.11-0.30) adult doses of platelets, and a significant decrease of 1.69 (95% CI: 1.45-1.93) units of plasma per 1000 population per annum. Seven other countries showed a general significant decreasing trend of RBC distributions. Higher blood distribution rates were observed in Taiwan. Therefore, the adoption of patient blood management is essential. [ABSTRACT FROM AUTHOR]
