A purpose-developed 15-item satisfaction questionnaire with demonstrated content validity (content validity index=1.00), internal consistency, and a confirmed 5-factor structure was distributed anonymously to all donors enrolled via telemedicine. Case completion time was recorded for all 146 cases with available time-log data.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Of the 168 eligible donors, 146 (86.9%) were enrolled via telemedicine, 16 (9.5%) by telephone, and 6 (3.6%) by mail. The confirmed-contact rate (telemedicine plus telephone) was 96.4% (162\/168). Because the prior mail-only system had no mechanism to confirm contact, a comparable rate was not available. The questionnaire response rate was 83.6% (122\/146). The median case completion time was 1.90 (IQR 1.42-2.50) hours. Overall satisfaction was 4.44 (SD 0.27) on a 5-point scale. The dimension-level Cronbach \u03b1 values ranged from 0.886 to 0.987. Completion time did not differ by sex, age, or follow-up reason (all P>.05).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The stepwise telemedicine protocol demonstrated high system coverage, rapid case completion, and high donor satisfaction. A residual digital divide (6\/168, 3.6% of donors were unreachable by digital means) underscores the need for hybrid follow-up strategies. These findings support broader implementation in blood banking services.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/95132","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T14:05:08Z","timestamp":1785506708000},"page":"e95132","source":"Crossref","is-referenced-by-count":0,"title":["A Stepwise Telemedicine Follow-Up System for Blood Donors in a University Blood Bank: Prospective Implementation Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2220-7742","authenticated-orcid":false,"given":"Ronnarit","family":"Boonyarat","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3089-3823","authenticated-orcid":false,"given":"Poonsup","family":"Sripara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3868-6656","authenticated-orcid":false,"given":"Namrin","family":"Boonmawongsa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2114-5632","authenticated-orcid":false,"given":"Boonsong","family":"Benjangkaprasert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8853-2353","authenticated-orcid":false,"given":"Weerasak","family":"Mahama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,7,31]]},"reference":[{"key":"ref1","unstructured":"Blood donor selection: guidelines on assessing donor suitability for blood donationWorld Health Organization201201012026-03-11https:\/\/www.who.int\/publications\/i\/item\/9789241548519"},{"key":"ref2","author":"Doerr, P","year":"2025","journal-title":"Guide to the Preparation, Use and Quality Assurance of Blood Components 22nd Edition"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.transci.2025.104068"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.67462"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.2196\/62762"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(24)01085-7"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111\/vox.13796"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1258\/jtt.2012.120219"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.2196\/43601"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.htct.2023.11.013"},{"key":"ref11","unstructured":"How LINE has become Thailand's everyday life \u2015 the strategy and future of LINE as Thailand's national infrastructureLY Corporation20251252026-06-14https:\/\/www.lycorp.co.jp\/en\/story\/20251205\/line_thailand.html"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-023-09816-7"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)61602-X"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1097\/00006199-198611000-00017"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002\/nur.20147"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1007\/s11165-016-9602-2"},{"key":"ref17","doi-asserted-by":"crossref","DOI":"10.4324\/9780429056765","author":"George, D","year":"2019","journal-title":"IBM SPSS Statistics 26 Step by Step: A Simple Guide and Reference"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1177\/1357633X20960638"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.2196\/56312"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2196\/65380"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.2196\/71349"}],"container-title":["JMIR Formative Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/formative.jmir.org\/2026\/1\/e95132","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T14:05:15Z","timestamp":1785506715000},"score":1,"resource":{"primary":{"URL":"https:\/\/formative.jmir.org\/2026\/1\/e95132"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,31]]},"references-count":21,"URL":"https:\/\/doi.org\/10.2196\/95132","relation":{"has-preprint":[{"id-type":"doi","id":"10.2196\/preprints.95132","asserted-by":"object"}]},"ISSN":["2561-326X"],"issn-type":[{"value":"2561-326X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,31]]}}}
