Abstract: Objective To analyze the causes of apheresis blood donors loss in Yinchuan area, and to work out the call-back strategy. Methods A total of 1 498 blood donors whose last blood donation time was between January 1, 2019 and December 31, 2020 in Yinchuan area were called one by one. SPSS 26.0 software was used for statistical analysis. Variables between different groups were compared usingχ² test, and P<0.05 was considered statistically significant. Results Three hundred and fifty-five people (23.7%) were successfully called back. Compared with the failed call-back group, there was no significant difference in gender (P>0.05), but there were significant differences in age, nationality, occupation, education level and blood type (P<0.05). People aged 18-24, with Han Nationality, working in national enterprises or institutions, or with graduate degree or above had the highest call-back rate; with the increase of age and the decrease of education level, the success rate of call-back decreased. Among the reasons for call-back failure, no free time accounted for the largest proportion, followed by being in other places, physical reasons, donors of relatives and friends, losing contact, graduated from school, misunderstanding of blood donation, and inconvenient parking. Conclusion We will continue to optimize and refine the apheresis blood donation service, make the work more humanized, expand the publicity of the positive image of blood donation, and innovate constantly, so as to retain the blood donors.
