Study on the Construction of Family Support System for Unrelated Hematopoietic Stem Cell Donation Volunteers

There are millions of patients in urgent need of hematopoietic stem cell transplantation in China, but the matching success rate of unrelated hematopoietic stem cells is only 1/400 ~ 1/10000. Since the establishment of China Bone Marrow Bank in 1992, only more than 14,000 patients have been successfully matched. According to the survey, a large number of volunteers in China will eventually choose to refuse to donate hematopoietic stem cells, which is closely related to the public's lack of understanding of hematopoietic stem cell donation. Unrelated volunteers can get less support from family members than related hematopoietic stem cell donors, which leads to their lower donation rate. Therefore, it is of great practical significance to study the family support system of unrelated hematopoietic stem cell donation volunteers.
