Summary
Hematopoietic stem cell donation (HSCD) volunteer retention is a global challenge. This study found that sampling methods and demographics significantly impact HSCD volunteer retention, with swab sampling showing better results in younger individuals.
Area of Science:
- * Hematology and Transplant Immunology
- * Public Health and Donor Management
Background:
- * Significant global loss of hematopoietic stem cell donation (HSCD) volunteers poses a challenge to transplant programs.
- * Understanding factors influencing volunteer retention is crucial for maintaining donor registries.
Purpose of the Study:
- * To analyze volunteer retention characteristics based on swab versus blood sampling approaches.
- * To identify demographic factors associated with volunteer retention in HSCD programs.
Main Methods:
- * Telephone follow-up survey of 18,963 volunteers from the Shanghai Bone Marrow Donation Program.
- * Analysis of volunteer retention using multiple logistic regression.
- * Visualization of retention trends using forest plots.
Main Results:
- * Severe volunteer loss observed, with only 32.37% of volunteers successfully contacted.
- * Volunteer retention is influenced by sampling methods and demographic characteristics.
- * Swab sampling showed better retention among young individuals and technicians; blood sampling had lower retention among public officials and workers.
Conclusions:
- * Enhancing contact channels, frequency, and volunteer education is vital for improving HSCD volunteer stability.
- * Tailoring strategies based on demographic profiles and sampling methods can optimize donor retention.
