献血优待证对广州献血行为的影响
The impact of the Guangzhou voluntary blood donation privilege certificate on blood donation behavior:an inter-rupted time series analysis
摘要
Abstract
Objective To evaluate the causal effects and population heterogeneity of Guangzhou's Voluntary Blood Do-nation Privilege Certificate Policy on blood donation behavior,and to provide empirical evidence for optimizing blood man-agement policies.Methods Using an interrupted time series(ITS)design,we analyzed 30 quarters of blood collection da-ta from Guangzhou Blood Center(from July 2018 to December 2025).Taking the third quarter of 2021 as the intervention node,we constructed ordinary least squares(OLS)regression models incorporating level and trend effects,and conducted stratified analyses by gender,age group,previous donation frequency,and per-donation volume.Results The tiered in-centive policy demonstrated significant heterogeneous effects.Apheresis donations showed sustained growth,with 2 units of component blood exhibiting a significant trend effect(β=304.58,P<0.001);high-frequency donors(11+times)demon-strated sustained growth trends in apheresis donations.For whole blood,immediate effects were significant for donors with 1-2 previous donations(β=4 537.55,P<0.001)and 3-10 previous donations(β=2 159.69,P<0.05);high-frequency do-nors(11-30 times)showed sustained growth trends(P<0.01).Stratified by per-donation volume,400 mL whole blood demonstrated a significant immediate effect(β=4 391.01,P<0.1),while 200 mL whole blood showed a significant decli-ning trend(β=-893.24,P<0.01).Conclusion The tiered incentive policy effectively enhanced blood donation partici-pation while maintaining the donors’altruistic motivations.Young and middle-aged adults primarily drove apheresis dona-tions.The policy demonstrated immediate incentive effects on low-frequency whole blood donors and long-term retention effects on high-frequency donors.Per-donation volume showed an"upward migration"trend,optimizing the blood collection structure.Differentiated outreach,conversion and retention strategies are recommended to further strengthen blood supply security.关键词
