Abstract:

Objective To understand the characteristics of seasonal supplies of suspended red blood cells and ABO blood types to the top 15 hospitals in Guangzhou from 2010 to 2019，in order to analyze the reasons， predict future development trends and offer rational solutions to ensure clinical blood use. Methods The distribution data on red blood cells from 15 hospitals for recent 10 years were collected to calculate amount of each quarter and blood type，respectively. Results A total of 2，723，978 U of red blood cells were distributed to 15 hospitals in the past 10 years，accounting for 71.09% of the total distribution（2，723，978/3，831，751.5），the total distribution was increasing year by year. The annual composition of red blood cell distribution in each quarter was relatively stable， the distribution amount was higher in the second and fourth quarters than in the first and third quarters. There were statistically significant differences in blood distribution among four seasons（F = 3.155，P < 0.05），and the differences between the first quarter and the second quarter or the fourth quarter were statistically significant（P < 0.05）. The annual composition of red blood cell distribution in each blood type was relatively stable；type O had the most distribution while type AB had the least distribution. There were also statistically significant differences in blood distribution among four blood types（P < 0.05）but the differences in the other groups were statistically significant except between A type and B type（P < 0.05）. Conclusions The distribution of red blood cells in 15 hospitals had been increasing year by year so that the shortage of seasonal and structural distribution had existed. All departments should adjust the strategies for blood collection and distribution in time including an increase in group blood dona⁃ tion ，accurate donor recruitment ，and rational distribution to alleviate the contradiction between supply and demand，thereby meeting the needs for clinical use.
