Background and objectives: For the prevention of blood shortages, it is essential for blood banks to design and implement donor recruitment and donor retention strategies that take into account the determinants of donor return.
Material and methods: We studied the behaviour of first-time blood donors in the region of Basel, Switzerland, between 1996 and 2011 and described factors associated with transition from active to inactive donor in two successive first-time donor cohorts (1996-2002, 2003-2008).
Results: The risk of becoming an inactive donor was associated with being younger and female, not being a 0-negative donor and living in an urban area. Over time, hazards of becoming an inactive donor were converging for individuals living in non-urban and urban areas as were those of younger and older donors. After their first donation, 73.6% and 67.5% of males in the 1996-2002 and 2003-2008 cohorts, respectively, donated at least once in the following 24 months. The proportion of returning female donors was 71.8% and 65.4%, respectively.
Conclusions: The increased volatility of first-time blood donors suggests that marketing actions and strategies aimed at increasing return rates should be reinforced, especially for younger and female blood donors.
