Factors influencing donor return.

BACKGROUND: To predict future blood donation behavior and improve donor retention, it is important to understand the determinants of donor return. STUDY DESIGN AND METHODS: A self-administered questionnaire was completed in 2003 by 7905 current donors. With data mining methods, all factors measured by the survey were ranked as possible predictors of actual return within 12 months. Significant factors were analyzed with logistic regression to determine predictors of intention and of actual return. RESULTS: Younger and minority donors were less likely to return in 12 months. Predictors of donor return were higher prior donation frequency, higher intention to return, a convenient place to donate, and having a good donation experience. Most factors associated with actual donor return were also associated with a high intention to return. Although not significant for actual return, feeling a responsibility to help others, higher empathetic concern, and a feeling that being a blood donor means more than just donating blood were related to high intention to return. CONCLUSION: Prior donation frequency, intention to return, donation experience, and having a convenient location appear to significantly predict donor return. Clearly, donor behavior is dependent on more than one factor alone. Altruistic behavior, empathy, and social responsibility items did not enter our model to predict actual return. A donor's stated intention to give again is positively related to actual return and, while not a perfect measure, might be a useful proxy when donor return cannot be determined.

Convenience, the bane of our existence, and other barriers to donating.

BACKGROUND: To prevent donor loss and improve retention, it is important to understand the major deterrents to blood donation and to identify factors that can be effectively addressed by blood centers. STUDY DESIGN AND METHODS: A 30-item self-administered questionnaire was completed in 2003 by 1705 first-time and 2437 repeat US donors who had not donated in 2 to 3 years. Asian, Hispanic, black, and white first-time and repeat donors rated the importance of deterrents to donation in their decision to not return with a 1 to 5 scale. Categorical analysis of variance methods were used to compare the importance of deterrents between first-time and repeat donors of different race or ethnicity. RESULTS: Not having a convenient place to donate was most commonly cited as an important or very important reason for not returning by 32 to 42 percent of first-time and 26 to 43 percent of repeat respondents. Although bad treatment and poor staff skills were less of a barrier than convenience, they were more important for minority donors. Other factors such as physical side effects, foreign travel, or length of the process appeared less important. CONCLUSION: Inconvenience is a major barrier to donating, suggesting that mobile collections and increased hours of operation might help recapture lapsed donors. The finding that lapsed minority donors were more likely to give bad treatment and poor staff skills as important reasons to not donate is disconcerting in light of the changing donor demographics and increased efforts to recruit these donors.

Transfusion-associated graft-versus-host disease: a serious residual risk of blood transfusion.

Transfusion-associated graft-versus-host disease (TA-GVHD) is well recognized as an uncommon, but frequently fatal, adverse effect of blood component therapy. In this disorder, viable donor lymphocytes transfused to a vulnerable patient orchestrate a devastating attack on the recipient's tissues. In contrast to the striking reduction in infectious risks of blood transfusion, a significant residual risk of TA-GVHD remains. This article reviews the pathogenesis and mechanism of TA-GVHD, which provide the foundation for a prevention strategy. A review of selected recent cases illustrates the challenges faced in the identification, prevention, and treatment of this frustrating disorder.
