Development and Evaluation of a Whiteboard Video Series to Support the Education and Recruitment of Committed Unrelated Donors for Hematopoietic Stem Cell Transplantation.

Whiteboard videos are a popular video format, allowing viewers to see drawings of concepts alongside explanatory text and speech. We hypothesized that whiteboard videos could support the education and recruitment of unrelated stem cell donors in Canada. A series of 5 sharable whiteboard videos about stem cell donation was produced and posted online in September 2018, including 1 full-length video (https://youtu.be/V4fVBtxnWfM) and 4 shorter videos titled "What Is Stem Cell Transplantation?" "How Does the Matching Process Work?" "How Are Stem Cells Donated?" and "How Can I Register as a Stem Cell Donor?" In the videos, metaphorical interpretations of stem cells as factories and genetic markers as barcode labels are employed to communicate complex concepts. The particular need for young, male, and ethnically diverse donors is reflected in the characters portrayed. Surveys demonstrated the videos (1) were used and valued by stakeholders in donor recruitment and (2) significantly improved objective and self-reported knowledge about stem cell donation and reduced donation-related ambivalence among viewers from the most-needed donor demographics. Use of the whiteboard videos was also associated with improved donor recruitment outcomes in Canada. Our work is relevant to donor registries and recruitment organizations worldwide that seek to improve their recruitment efforts.
