ABSTRACT
【Objective】 To explore the causes of apheresis platelet donors lapsing in Huzhou area, so as to provide basis for better maintenance of blood donor team. 【Methods】 The data of 1 128 platelet donors from November 1, 2018 to October 31, 2021 were collected, and they were divided into regular blood donor group and lapsed blood donor group, and their work situation, social relations and donation process were investigated through questionnaire survey.Based on the basic characteristics of blood donors, 15 variables were set and analyzed by t test, chi-square test and multivariate logistic regression analysis using SPSS 23.0 software. 【Results】 There were 602 (53.37%, 602/1 128) regular blood donors and 526 (46.63%, 526/1 128) lapsed blood donors in the donor bank during recent 3 years.No significant differences were found in age, gender, educational background, blood donation reaction as well as the satisfaction to service attitude and technical level of blood station staff between the two groups (P>0.05), but significant difference was noticed in whether they were freelancers or changed jobs recently, the working hours per week (h), whether they had friends who donated platelets, had relatives who received/had a serious disease, had children or not, whether satisfied with the frequency of recruitment, and whether the donation was convenient (P<0.05, P<0.01). Multivariate logistic regression analysis showed that recruitment frequency (OR=2.679), convenience of blood donation (OR=2.486), having friends who donated blood (OR=1.791), the working hours per week (OR=1.011), changing jobs (OR=0.558) and having children (OR=0.465) were included in the final regression model and were the influencing factors of blood donor lapsing(P<0.01). 【Conclusion】 Platelet donor lapsing is prominent in Huzhou, therefore efficient communication approaches should be established between blood stations, between blood donors and blood donor, and between blood banks; personalized service should be adopted to maintain apheresis platelet donors.
