Trend analysis of changes in blood donor populations in CSBT sentinel sites from 2021 to 2025
摘要
Abstract
Objective To analyze the structural changes in whole blood and apheresis platelet donations in Chinese So-ciety of Blood Transfusion(CSBT)sentinel units from 2021 to 2025,and to provide evidence for donor recruitment and blood service management.Methods Aggregated data reported by sentinel sites were collected and stratified according to six indicators:age,sex,donation history,donation volume,donation site,and organization mode.Pearson χ2 test,Cramer'V coefficient,Cochran-Armitage trend test and simple linear regression were adopted for analysis.Results A total of 16 256 973 whole blood donations and 1 576 546 apheresis platelet donations were included.Among whole-blood donations,the proportion of donors aged 18-22 years decreased from 27.30%to 10.60%.The proportion of male donors increased from 58.81%to 63.13%;the proportion of people aged 30 and above increased from 58.40%to 75.30%;the proportion of fixed locations rose from 28.37%to 36.57%;the proportion of social groups increased from 21.69%to 39.69%.The 400-mL do-nations decreased from 62.12%to 53.46%,while individually initiated voluntary donations remained above 50%.Aphere-sis platelet donations were predominantly from males,individuals aged 30-39 years,and repeat donors;2-treatment-unit a-pheresis platelet donations increased from 67.19%to 74.93%,and individually initiated donations accounted for 92.97%-96.02%.Statistically significant overall annual compositional differences were observed for all six indicators(all P<0.001),whereas linear trends for some sub-categories were not statistically significant.Conclusion In the participating CSBT sentinel units,among whole blood donations,the proportions of donors aged 18-22 years,university-organized group donations,and donations at blood mobiles decreased,whereas the proportions of organizational group donations and dona-tions at fixed venues increased.The apheresis platelet donation cohort is relatively mature and is evolving toward a high-effi-ciency donation model.Individual voluntary donation remains the primary organization mode for both donation types.Strate-gies such as youth donor recruitment,optimized layout of fixed donation sites,and retention of repeat donors should be strengthened to improve the resilience of blood supply.关键词
