Factors regarding blood donation willingness and preferences toward feedback between first-time donors and repeat donors in China: a cross-sectional survey

The factors influencing willingness differ significantly between first-time and repeat blood donors. Interventions should prioritize strengthening and disseminating knowledge among first-time donors to attract potential new donors. For repeat donors, enhancing the experience and implementing favorable policies are recommended to maintain donor pool. These targeted strategies would enhance donation rates in the future by governmental support.
