The potential impact of incentives on future blood donation behavior

BACKGROUND: It is important to assess the potential efficacy and safety of offering donation incentives as part of recruitment and retention programs. STUDY DESIGN AND METHODS : In 1995, 7489 allogeneic donors responded to an anonymous mail survey that inquired about demographics, donation history, infectious disease risks, and the potential appeal of incentives. RESULTS: The projected net effect of offering blood credits and medical testing would be to motivate, respectively, 58 percent and 46 percent of donors to return, whereas offering an item of limited value would motivate 20 percent to do so. First‐time and younger donors reported more frequently than repeat or older donors that incentives would appeal to them. Donors attracted by cash were 60 percent more likely to have a risk for transfusion‐transmissible infections (p = 0.03). Although not statistically significant, the odds of being an at‐risk donor were higher among individuals attracted by tickets to events (OR 1.5) and extra time off work (OR 1.2). CONCLUSION: These findings suggest that offering blood credits and (though to a lesser extent) items of limited value could be safe and effective strategies for retaining donors. Although medical tests were found to have broad appeal, studies are needed to identify tests in which donors would be most interested.
