How first-time platelet donors become regular donors: the influencing factors / 中国输血杂志

ABSTRACT

【Objective】 To analyze the related factors affecting first-time platelet donors to become regular donors in Guangzhou in 2018, so as to provide reference for the retention of platelet donors. 【Methods】 The data of 4 361 first-time platelet donors in Guangzhou in 2018, including age, gender, initial donation unit, time for the primary and secondary donation were collected. The relevant factors affecting first-time blood donors to become regular donors were analyzed by Logistic regression analysis. 【Results】 Among the influencing factors, first-time donors returned in the first month were more likely to become regular donors (5.569 times that of those did not return)(OR 95% CI: 4.748~6.533, P<0.05). First-time donors who aged 45~60, and initially donated 2 units were more likely to become regular donors than those aged 18~24(1.857 times) (OR 95% CI: 1.413~2.441, P<0.05), and those initially donated only one unit (1.695 time) (OR 95% CI: 1.486~1.933, P<0.05). 【Conclusion】 The returning in the first month, age and initial donation units predict long-term commitment for first-time donors. Encouraging first-time platelet donors to return within 1 month is more likely to convert them into regular blood donors.
