Regular whole blood donaion in Tianjin from 2013 to 2022
Objective To analyze the situation of regular whole blood donation in Tianjin between 2013 and 2022,in order to provide data support for improving the recruitment and retention measures of regular blood donors and ensur-ing safe clinical blood supply.Methods From 2013 to 2022,185 639 regular whole blood donors in Tianjin were select-ed as the study group and 1 015 312 other whole blood donors in the same period were selected as the control group.The demographic data,blood collection volume and blood retest screening of blood donors in the two groups were statistical-ly analyzed.Results The number of regular blood donors and the volume of blood donated in Tianjin increased year by year from 2013 to 2022,with an average annual growth rate of 6.22％and 6.18％,respectively.From 2013 to 2021,the retention rate of regular blood donors increased first and then decreased.The proportion of male blood donors in the study and control groups showed a decreasing trend but the proportion of female donors showed an increasing trend,with the proportion of male donors in the study group higher than that in the control group and the proportion of female donors lower than that in the control group(both P＜0.05).In the study group,the majority of blood donors were in the age of 26-35 years old,followed by those of 36-45 years old;in the control group,the majority of blood donors were in the age of 18-25 years old,followed by those of 26-35 years old;the proportion of blood donors in the study group in the age of 18-25 years old was lower than that in the control group,while the proportion of blood donors of other age group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The rates of 200 mL and 300 mL blood donations and insufficient blood donations in the study group were lower than those in the control group,while the rate of 400 mL blood donations was higher than that in the control group,and the differences were statis-tically significant.Among the blood donors in the study group,the proportion of students,civil servants,medical work-ers,military personnel,teachers and others was lower than that of the control group,while the proportion of the rest occu-pations was higher in the study group than that of the control group,and the differences were all statistically significant.There was a significant difference in the proportion of regular blood donors among blood donors of different professions.The re-test deferral rates of ALT and anti-TP in the study group showed a decreasing trend followed by an increasing trend,and the re-test deferral rates of HBV,HCV and HIV showed an increasing trend followed by a decreasing trend,and all the re-test deferral rates in the study group were lower than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion From 2013 to 2022,the situation of regular blood donors in Tianjin has a certain regularity,and there is certain room for growth.Precise recruitment strategies targeting different populations should be adopted to have more regular blood donors.
