Abstract:
This study addresses the challenge of low blood donation rates in developing countries by examining the effectiveness of a barrier-removal incentive-a one-day transportation voucher-to promote blood donation. Utilizing a longitudinal dataset of 23,750 donors from a Brazilian blood collection agency (BCA) collected between March 2018 and May 2020, we examine the short and long-term effects of this campaign on donation rates. Our results show that the incentive had a large positive influence on both donation attempts and successful donations on the day of the campaign. However, the short-term success of the intervention had an unintended consequence: the significant increase in prospective donors\' waiting time at the BCA during the intervention day, which may help explain the negative impact on return rates in the 24-month follow-up. Despite these opposing outcomes, the net effect of the one-day blood donation incentive was still positive, offering valuable insights for BCAs aiming to enhance donor recruitment and retention strategies and emphasizing the need to balance immediate benefits with potential long-term impacts.
摘要:
这项研究通过研究消除障碍的激励措施-一天的交通代金券-促进献血的有效性,解决了发展中国家献血率低的挑战。利用2018年3月至2020年5月期间收集的来自巴西血液采集机构(BCA)的23,750名捐赠者的纵向数据集,我们研究了这项运动对捐赠率的短期和长期影响。我们的结果表明,激励措施对运动当天的捐赠尝试和成功捐赠都有很大的积极影响。然而,干预的短期成功带来了意想不到的后果:在干预日期间,潜在捐赠者在BCA的等待时间显着增加,这可能有助于解释24个月随访对回报率的负面影响。尽管有这些相反的结果,一日献血奖励的净效果仍然是积极的,为BCA提供有价值的见解,旨在加强捐助者的招募和保留策略,并强调需要在眼前的利益与潜在的长期影响之间取得平衡。
