RESUMO
【Objective】 To investigate the re-donation willingness and its influencing factors of street blood donrs, so as to stable the team of blood donors and enhance the efficiency of blood collection. 【Methods】 From July 2021 to December 2022, 1 210 blood donors were randomly selected from 5 street blood donation sites affiliated to Nantong Central Blood Station, and their willingness to re-donate blood and influencing factors were surveyed via telephone interviews within 24 hours and 2 to 3 weeks after blood donation. The frequency and type of adverse donation reactions (ADRs) was gathered. 【Results】 Among 1 210 street blood donors, 590 were first-time blood donors, accounting for 48.76% (590/1 210), and 620 were repeated blood donors, accounting for 51.24% (620/1 210). The response rate of this survey was 96.03% (1 162/1 210), and the incidence of delayed ADRs was 1.29% (15/1 162) according to telephone interviews after blood donation. Among the 620 repeated blood donors, "health promotion" (61.77%, 383/620) was the most important reason for willingness of redonation(P<0.05), and the top of the list for on-site experience was "blood donation locations" (56.61%, 351/620) (P< 0.05). 【Conclusion】 The intention of blood donors, location of blood donation sites, service and publicity of blood donation are the main factors that affect the re-donation of blood donors. It's vital to increase the proportion of blood re-donation, and promote the development of voluntary blood donation by improving blood donation service, policy popularization and incentive measures.
RESUMO
【Objective】 To explore the promote and deter factors of blood donation among street blood donors in Nanjing, in order to improve the accuracy of street blood donors recruitment. 【Methods】 A questionnaire with high confidence was designed based on the theory of planned behavior(TPB). The multi-stage hierarchical sampling method was adopted according to the geographical location and economic development level of 11 districts(regions) in Nanjing, and the street blood donors were divided into three groups according to the history of blood donation: one donation(n=361), donation numbers ≥ 2(n=417)and non-donation (n=241). The blood donation behavior was investigated from four aspects as external promote factors (such as seeking a free blood examination, self-interest factors, etc.), internal promote factors(such as altruistic, self-interest factors, blood donation can help others, etc.), external deter factors (too busy to donate blood, opposition from my family, etc.) and internal deter actors ( worry about dizziness after blood donation, fear of needles, ect.). The database was established using Epidata software, and chi-square test was applied for statistical analysis between groups. 【Results】 The groups mainly affected by the promote factors (altruistic and self-interest factors) of Nanjing street population in blood donation were unmarried, 18~24 years old, childless, below bachelor degree, and have barely no income. The main groups less affected by the deter factors were students, male, unmarried, 18~24 years old, childless and have barely no income.Promote factors increases with the number of blood donations, while deter factors decreases with the number of blood donation. 【Conclusion】 TBP can better analyze and explain the promote and deter factors affecting blood donation behavior among street blood donors in Nanjing, which is helpful for blood stations to formulate targeted measures to improve the availability of street blood donors.
RESUMO
【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.
