Analysis on the factors influencing the return of deferred apheresis platelet donors due to abnormal health examination before donation / 现代医院

ABSTRACT

Objective Analyze the characteristics of delayed apheresis platelet donors due to health consultation or ex-amination,and the influencing factors of recall in Guangzhou,and to provide evidence for recruitment strategy.Methods 5 960 delayed apheresis platelet donors from January fisrt,2022 to June 30th,2022 were collected in Guangzhou Blood Center and fol-lowed up to August31th,2023.Logistic regression analysis was used to analyze the influence of sex,age,times of blood donation and length of blood donation on recall.Results Among the 5 960 delayed platelet donors,164(2.75%)were permanently un-suitable for blood donation.The most common reason was allergy.Among the 5 796(97.25%)delayed blood donors,the most common reason was abnormal blood routine.Analysis of factors associated with delayed donor recall found that male donors were more likely than female donors[OR =1.16,95%CI(1.01,1.34)],blood donors aged 26-35[OR =1.65,95%CI(1.41,1.92)],36-45[OR=1.90,95%CI(1.55,2.31)]or 46-60[OR =2.63,95%CI(1.96,3.53)]compared with those aged 18-25,blood donors who were blocked forless than 14 days[OR =4.22,95%CI(2.73,6.52)]orfor 15-89 days[OR =5.24,95%CI(3.42,8.03)]compared with those who were blocked for more than or equal to 90 days,the recall rate of repeat donors was higher than that of first-time donors[OR=6.78,95%CI(5.62,8.19)].Conclusion In order to improve the recall rate of apheresis platelet donors,we should pay more attention to the education of young donors and first-time donors,also consider a voluntary recall by text message or phone after a donor has been prevented from donating blood.
