Changes in the Whole Blood Donor Population in South-West Germany: 2010 versus 2016

In the recent past, the discrepancy between blood supply and future demand may have been overestimated. As medical progress develops rapidly, it will be essential to monitor ongoing demographic changes in the donor population regularly and to re-evaluate retention and recruiting strategies. The aim of the current study was to compare first-time donor (FTD) characteristics and their return rates. We therefore compared whole blood (WB) donations in total and the annual donation frequencies in 2010 and in 2015/2016. Furthermore, we evaluated whether over the same observation period, medical reasons for deferral underwent a change (2010 vs. 2015)
