BACKGROUND: The continual identification of rare blood among donors is critical to support national programs like the American Rare Donor Program (ARDP). Some blood centres require consent from donors to be registered with a national registry. This situation provides an opportunity to determine whether a donor's willingness to register is associated with a change in donation behaviour.
METHODS: Rare donors were identified by molecular typing. The average number of donations per year was compared for each donor prior to and after receiving a consent letter. Donors were categorized as either accepting or declining the request. Non-parametric t tests compared the statistical significance within and between categories. Rare types were overlaid with consensus data to look for trends using data visualization techniques.
RESULTS: A total of 270 molecularly typed rare donors received letters over 4 years. Half of the donors (132, 49%) agreed to participate in the ARDP. Overall, donation frequency increased after the letter when enrolled. Both Caucasian and non-Caucasian donors increased their donations after enrolling providing an additional 159 red blood cell units over 3 years. Declining participation did not change donation frequency. Data visualization showed that enrolled donors were more affluent, high school and college educated, and lived in their home for longer periods of time.
CONCLUSION: A donor's willingness to enrol in the ARDP was associated with a post-response increase in donation frequency. New interventions to reach non-Caucasian donors may be a prerequisite to increase donation frequency and a willingness to be a rare blood donor.
