Results Among 3073 subjects, blood donors were enrolled in a control group of 1935 platelet donors again or repeatedly within 24 months of their first platelet donation,1138 patients who donated only once were included in the observation group, and the loss rate of platelet donors was 37.03%. Univariate analysis showed that there were statistically significant differences in age, gender, self-perceived health status, occupation, education level, cognition level of blood donation, motivation of blood donation and experience of blood donation between the two groups (P<0.05). Multivariate analysis showed that age, cognition level of blood donation, motivation of blood donation and experience of blood donation were the influencing factors for loss of apheresis platelet donors (P<0.05).
