Research on the Current Situation and Countermeasures of Decreasing Blood Collection for Voluntary Blood Donation after the COVID-19 Pandemic (with Global Implications)

Data and Methods : This study takes the blood information data of Jiangsu Provincial Blood Center in China from 2019 to 2025 as the core basis, and combines multiple rounds of interviews to systematically analyze the characteristics of changes in the supply and demand of voluntary blood donation before and after the epidemic from both quantitative and non-quantitative dimensions. Result : The collection volume of whole blood showed a significant fluctuation trend of "steady increase at first and then sudden drop", reaching a peak in 2021 and then continuously declining. By 2025, it had decreased by nearly 30% compared with 2021. Discussion : Through in-depth exploration, it was found that four core factors, namely, cognitive biases regarding personal health conditions, the sharp increase in life pressure after the epidemic, the obstruction in the implementation of incentive policies, and the misleading negative public opinion, jointly restrict the development of voluntary blood donation. Countermeasures : This study specifically proposes three major directions: "Construction of a gradient incentive policy system", "improvement of public opinion guidance mechanism", and "legalized blood donation guarantee system", and elaborates on the specific implementation paths, after the COVID-19 pandemic Provide scientific decision-making references for establishing a long-term mechanism for voluntary blood donation globally and ensuring the safety of blood use for public health.
