Why did street blood donors re-donate or lapse? A analysis in Nanjing / 中国输血杂志

ABSTRACT

【Objective】 To analyze the influencing factors of blood re-donation among street voluntary blood donors in Nanjing, and to provide basis for increasing the proportion of blood donation/donors. 【Methods】 29 650 street voluntary blood donors in Nanjing from May 21, 2017 to May 21, 2018 in the information management system of Nanjing Red Cross Blood Center were taken as the sampling population, and 2 965 (10%) were randomly selected to ask whether they donated again and reasons by telephone calls. They were divided into re-donation group and lapsed group.The demographic variables and donation frequency of street blood donors in the two groups were analyzed and compared by Chi-square test, and multivariate logistic regression was used to analyze the influencing factors of re-donation of blood donors. 【Results】 The response rate of this survey was 63.37% (1 879/2 965), and the re-donation rate of street blood donors in Nanjing from May 2017 to May 2018 was 40.34% (758/1 879), which was lower than the re-donation rate of global blood donors as 50%. The primary motivation for street blood donors in Nanjing to donate blood again was "help others", accounted for 62.27% (472/758), and the primary deterrent to redonate blood again was "too busy to donate blood", accounted for 49.15% (551/1 121). 【Conclusion】 There is a certain gap between the rate of blood re-donation in Nanjing and worldwide, therefore, further incentive measures are needed and flexible recruitment and blood donation methods should be adopted to facilitate blood donation for donors.
