Abstract
BACKGROUND: Frequent blood donors are an important resource as they contribute many donations over their lifetime. The aim of this research was to develop a demographic profile of Australian frequent whole blood donors and to determine predictors of lapse within this group. STUDY DESIGN AND METHODS: Routinely collected data were used to profile individuals who had donated whole blood frequently (three or more times) between December 2010 and November 2011. Two segments were identified: 1) existing donors who had donated before December 2010 and 2) new donors who had not donated before December 2010. Donation records were followed to the end of December 2013 to examine retention. RESULTS: A total of 90,867 donated frequently between December 2010 and November 2011. The group was composed of slightly more men (51.4%), was typically of middle socioeconomic status, and many were employed in skilled trades such as a builder or a plumber (21.3%). Existing donors (n = 81,762) were significantly older, more likely to be male, and more likely to have a D- blood type compared to the smaller group of new donors (n = 9105). For both segments, being older and male and having a D- blood type increased the likelihood of return in the follow-up period. Deferrals and adverse events had negative impacts on retention for both groups. CONCLUSIONS: This study highlights specific factors that blood collection agencies may focus on to support continued donation among frequent donors.
