长沙地区反应性献血者归队情况回顾性分析OACSTPCD

Objective To analyze the reentry of single reagent reactive voluntary blood donors in our center,in order to provide data support and reference for the recall of single reagent reactive blood donors.Methods Collect the information of eligible blood donors from the information system of our center from January 2019 to September 2023 were collected,and the reentry were tracked and retrospectively analyzed.The demographic characteristics,active reentry rate,and re-donation rate of eligible blood donors were analyzed,and the differences between qualified reentry rates and factors affecting re-donation were compared using chi-square test.Results A total of 3361 blood donors met the reentry criteria,with an active reentry rate of 2.7%(91/3361)and a qualified reentry rate of 80.21%(73/91).The reentry rate of eligible blood donors showed significant differences in terms of different genders(3.3%vs 2.1%),educational background(3.7%vs 2.3%),blood dona-tion frequency(9.3%vs 4.0%vs 1.3%),testing items(7.7%vs 2.7%vs 1.9%vs 1.3%)and blood donation types(18.1%vs 2.0%)(P<0.05).Difference was noticed in the qualified rate of blood donor reentry among different age groups(61.1%vs 94.4%vs 81.8%)(P<0.05).A total of 126 blood donors donated again,with a total volume of 47800 mL,a re-donation rate of 49.3%(36/73)and a qualified rate of re-donation of 98.4%(124/126),showing a difference between repeat blood donors and first-time donors(P<0.05).Conclusion The active reentry rate of single reagent reactive blood donors in our center is relatively low,but the qualified rate of reentry and the re-donation rate are both high.The re-donation is mainly do-nation of apheresis platelets,and successful reentry blood donors have a strong willingness to donate blood.
