A quasi-experimental study was conducted to evaluate the effectiveness of a pay-it-forward strategy for increasing influenza vaccination among children and older adults compared to a self-paid vaccination strategy in China. Pay-it-forward is an innovative community-engaged intervention in which participants receive a free influenza vaccination and are then asked if they would like to donate or create a message to support subsequent vaccinations. This economic evaluation used a decision-tree model to compare pay-it-forward to a standard of care arm in which patients had to pay for their own influenza vaccine. The analysis was performed from the healthcare provider perspective and costs were calculated with 2020 United States dollars. The time horizon was one year. In the base case analysis, pay-it-forward was more effective (111 vs 55 people vaccinated) but more costly than standard-of-care ($4477 vs $2725). Pay-it-forward spurred 96.4% (107/111) of individuals to voluntarily donate to support influenza vaccination for high-risk groups in China. Further costing and implementation research is needed to inform scale up.
在中国，开展了一项准实验研究，以评估与自费接种策略相比，“传递爱心”策略在增加儿童和老年人流感疫苗接种方面的有效性。“传递爱心”是一种创新的社区参与干预措施，参与者可免费接种流感疫苗，然后会被询问是否愿意捐赠或留下信息以支持后续接种。这项经济评估使用决策树模型，将“传递爱心”策略与患者必须自费接种流感疫苗的标准治疗组进行比较。分析是从医疗服务提供者的角度进行的，成本以2020年美元计算。时间跨度为一年。在基础案例分析中，“传递爱心”策略更有效（接种人数为111人，而标准治疗组为55人），但成本也更高（分别为4477美元和2725美元）。“传递爱心”策略促使96.4%（107/111）的人自愿捐赠，以支持中国高危人群的流感疫苗接种。需要进一步进行成本核算和实施研究，为扩大规模提供依据。
