Converting first-time donors to become regular donors continues to be a challenge facing blood centres. We examined whether first-time donors with frequent return in the first 12 months were more likely to become regular donors.
The donation histories of 179 409 community whole-blood donors, whose first-time donation in 1991 was negative on donor screening tests, were evaluated. Donors were categorized by the number of donations made in the 12 months after (and including) their first donation. The donor return pattern in the subsequent 6 years, and its association with first-year donation frequency and demographics, was evaluated by using logistic regression analysis. A 'regular donor' was defined as one who returned to donate in at least 4 of the 6 years of follow-up.
First-year donation frequency was significantly correlated with long-term donor return (P < 0.0001). Among those giving 1, 2, 3, 4 and > or = 5 donations in the first year, 4%, 11%, 21%, 32% and 42%, respectively, became regular donors (P < 0.0001). Similar associations between donation pattern and donor return behaviour were observed after adjusting for demographic variables (P < 0.0001).
Strategies aimed at encouraging current donors to donate more frequently during the first year may help to establish a regular donation behaviour.
促使首次献血者转变为定期献血者一直是血液中心面临的一项挑战。我们研究了在最初12个月内频繁回访的首次献血者是否更有可能成为定期献血者。
对179409名社区全血献血者的献血记录进行了评估，这些献血者于1991年首次献血，且献血者筛查检测结果为阴性。根据首次献血后（包括首次献血）12个月内的献血次数对献血者进行分类。采用逻辑回归分析评估后续6年的献血回访模式及其与第一年献血频率和人口统计学特征的关联。“定期献血者”定义为在6年随访期内至少有4年回来献血的人。
第一年的献血频率与长期献血回访显著相关（P<0.0001）。在第一年分别献血1次、2次、3次、4次及≥5次的人群中，成为定期献血者的比例分别为4%、11%、21%、32%和42%（P<0.0001）。在对人口统计学变量进行校正后，观察到献血模式与献血回访行为之间存在类似的关联（P<0.
