A Study of Key Factors Influencing the Willingness of RhD-negative Blood Donors to Donate Blood in Chongqing, China, 2017-2019

The importance of RhD-negative blood in clinical blood transfusion is becoming more and more prominent with the continuous advancement of medical technology, but the resources of blood donors are especially precious due to their rarity. As a densely populated area, the recruitment and retention of RhD-negative blood donors in Chongqing Municipality is crucial to ensure clinical blood supply. In this study, a questionnaire survey method was used to collect 1,200 valid questionnaires from RhD-negative blood donors in Chongqing Municipality during 2019-2021 by random sampling. The questionnaires covered the donors' knowledge of RhD-negative blood, knowledge of blood donation policy, motivation to donate blood, experience of blood donation and willingness to donate blood again. The data were statistically analyzed using SPSS software to explore the key factors affecting the willingness to donate blood through descriptive statistics and chi-square test. The results showed that factors such as donors' knowledge of RhD-negative blood, knowledge of blood donation policy, motivation and experience of blood donation significantly affected willingness to donate blood. Therefore, measures such as strengthening the publicity of RhD-negative blood knowledge, improving the blood donation policy, and upgrading the quality of blood donation services are recommended to promote the stable development of the RhD-negative blood donor workforce, to meet the urgent clinical demand for RhD-negative blood, and at the same time to enhance the satisfaction of the donors and the blood donation rate.
