This study analyzed the distribution characteristics of volunteer retention between the swab sampling approach and blood sampling approach. The Shanghai branch of the China Bone Marrow Donation Program conducted a telephone follow-up with 18,963 volunteers to understand volunteer retention. Multiple logistic regression was used to analyze the distribution characteristics of volunteer retention between two different sampling approaches, and a forest plot was used to observe the distribution trend. Only 32.37% of the volunteers could be contacted, and the loss of volunteers was severe. The volunteer retention is influenced by sampling approaches and demographic characteristics, and Shanghai natives, the highly educated, and students had better retention. The volunteer retention of the swab group was better among young people and technicians, while the volunteer retention of the blood sample group was lower among public officials and workers, and the volunteer retention in the blood sample group was more significantly affected by changes in population characteristics. To enhance the stability of volunteers, managers should improve the contact channels and frequency, expand the ratio of stable volunteers, strengthen volunteer education in the process of collecting blood samples, and respect individuals\u2019 willingness.<\/jats:p>","DOI":"10.3390\/ijerph18084027","type":"journal-article","created":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T05:52:00Z","timestamp":1618206720000},"page":"4027","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Study on Hematopoietic Stem Cell Donation Volunteer Retention between Swab Sampling Approach and Blood Sampling Approach: Evidence from Shanghai, China"],"prefix":"10.3390","volume":"18","author":[{"given":"Ke","family":"Yan","sequence":"first","affiliation":[{"name":"Department of Health Policy and Management, School of Public Health, Fudan University, Shanghai 200032, China"},{"name":"China Research Center on Disability Issues, Fudan University, Shanghai 200032, China"},{"name":"Key Laboratory of Health Technology Assessment, National Health Commission, Fudan University, Shanghai 200032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Red Cross Society of China Shanghai Branch, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guoqiang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Red Cross Society of China Shanghai Branch, Shanghai 200040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baosong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, School of Public Health, Fudan University, Shanghai 200032, China"},{"name":"China Research Center on Disability Issues, Fudan University, Shanghai 200032, China"},{"name":"Key Laboratory of Health Technology Assessment, National Health Commission, Fudan University, Shanghai 200032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, School of Public Health, Fudan University, Shanghai 200032, China"},{"name":"China Research Center on Disability Issues, Fudan University, Shanghai 200032, China"},{"name":"Key Laboratory of Health Technology Assessment, National Health Commission, Fudan University, Shanghai 200032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"167","DOI":"10.1016\/j.autrev.2005.06.003","article-title":"Hematopoietic stem cell transplantation (HSCT): An approach to autoimmunity","volume":"5","author":"Alaez","year":"2006","journal-title":"Autoimmun.
