Understanding the donors' behavior to donate blood improves blood donor retention programs. The purpose of this study is to evaluate the return rate of first\u2010time blood donors following different interventions to identify effective ways to retain first\u2010time donors.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN AND METHODS<\/jats:title><jats:p>The study was conducted on 1356 first\u2010time blood donors at four main blood centers in Iran. The donors were randomly assigned based on different interventions (phone calls, educational letter, emotional letter, incentive, motivational meeting, and no intervention) to six groups. The return rate of donors was defined as a second attempt to donate within 6 months after the first donation. Return rate and 95% confidence intervals (CIs) were calculated and compared among different groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A total of 394 (29%) donors returned within 6 months for a second donation (95% CI, 0.26\u20100.31). The return rate in the emotional letter group, educational letter, phone reminder, incentives, motivational meeting, and control groups was 36% (95% CI, 0.31\u20100.42), 33.2% (95% CI, 0.27\u20100.38), 31.5% (95% CI, 0.25\u20100.37), 30% (95% CI, 0.22\u20100.38), 22% (95% CI, 0.17\u20100.27) and 22.1% (95% CI, 0.17\u20100.27), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>This study provides evidence supporting the fact that more first\u2010time blood donors can be motivated to donate again by implementing targeted interventions. It demonstrates that emotional letters, educational letters, and phone reminders were effective in improving the return rate of first\u2010time donors.<\/jats:p><\/jats:sec>","DOI":"10.1111\/trf.15404","type":"journal-article","created":{"date-parts":[[2019,6,20]],"date-time":"2019-06-20T06:34:41Z","timestamp":1561012481000},"page":"2893-2898","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Effective ways to retain first\u2010time blood donors: a field\u2010trial study"],"prefix":"10.1111","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4876-538X","authenticated-orcid":false,"given":"Shirin","family":"Hashemi","sequence":"first","affiliation":[{"name":"Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2885-8354","authenticated-orcid":false,"given":"Mahtab","family":"Maghsudlu","sequence":"additional","affiliation":[{"name":"Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soheila","family":"Nasizadeh","sequence":"additional","affiliation":[{"name":"Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilda","family":"Esmaielifar","sequence":"additional","affiliation":[{"name":"Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali Akbar","family":"Pourfathollah","sequence":"additional","affiliation":[{"name":"Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,6,19]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.13676"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0000000000001242"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.transci.2017.12.001"},{"key":"e_1_2_8_5_1","first-page":"1","article-title":"The elderly population in Iran: an ever growing concern in the health system","volume":"6","author":"Noroozian M","year":"2012","journal-title":"Iran J Psychiatry Behav Sci"},{"key":"e_1_2_8_6_1","unstructured":"World meters.Iran Population 2019.
