Abstract: Objective To analyze the influencing factors of reluctant donation of apheresis platelets, so as to provide evidence for improving the blood donation and its coping strategies. Methods The data of apheresis platelet donors were collected at the blood center, and the willingness of re-donations was randomly followed-up. Results A total of 1 160 donators with experience of apheresis platelet donation within one year received telephone follow-ups. Among them 17.52% (89/508) were at age below 25, followed by 26-35 (45.87%, 233/508), 36-45 (28.15%, 143/508), 46-55 (8.07%, 41/508) and 56-60 (0.39%, 2/508). There were 508 (43.79%) of the donors who expressed reluctance to re-donation, and among them, 388（76.38%）were males and 120（23.62%）were females. The main reasons for unwillingness to re-donation included lost touch with blood donors (59.84%, 304/508), no time (16.73%, 85/508), physical conditions ( 8.07%, 41/508) , long distance work or study (8.07%, 41/508), missed calls (6.89%, 35/508), and bad experience (0.39%, 2/508). Conclusion The common reasons for the loss of apheresis platelets donors were the failure to keep in contact with them. Therefore, it is necessary to improve the documentation, updating the information and communications with the donors for re-donation of apheresis platelets.
