Evaluation and improvement of blood donor educational materials: results from a multicenter randomized controlled

Background:
Blood collection centers are charged with creating donor educational materials (DnEM) that are easily understood across all prospective donor populations, while addressing mandates and recommendations from regulatory agencies and professional standard setting organizations. Donors must have sufficient information to understand the donation process with its risks and benefits, time to consider options before deciding, and opportunity to choose whether to proceed with or decline donating. The goal of this multisite randomized controlled trial was to evaluate knowledge acquired using standardized DnEM. America's Blood Centers' Working Group (WG) for Donor Education and Communication was formed to evaluate and suggest modifications of these documents. Based on pilot work, a randomized clinical trial was designed to test donor knowledge across a variety of populations. The WG identified several shortcomings in the current DnEM and proposed new DnEM. The new DnEM were tested against the same, current DnEM being used at all three sites (Blood Donor Educational Material, 2016 version 2.0, published in conjunction with the AABB uniform donor history questionnaire).
Methods And Materials:
One-hundred sixty-five first time and returning donors were randomized in a 2x2 model to review either new DnEM or current DnEM. Every participant completed a pre- and post-quiz that tested their understanding of the DnEM.
Results:
Returning donors had greater baseline knowledge compared to new donors, but new donors improved more versus returning donors. Donors using the new DnEM showed greater improvement in knowledge than those using current DnEM.
Conclusion:
Comprehension of DnEM can be improved. With this sample size the results suggest that the findings are independent of demographic characteristics, but a larger study would be necessary to confirm this.
