Secular trends in the distribution of allogeneic blood components in Taiwan

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.
