To date, predictive factors for MT during LTx are unknown. This study aimed to establish a predictive model for intraoperative MT in patients undergoing LTx to provide personalized risk prediction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study included adult patients who underwent LTx at the Second Affiliated Hospital of the Zhejiang University School of Medicine between 2020 and 2023. MT was defined as an intraoperative transfusion of &amp;gt; 5 units of packed red blood cells. The dataset was randomly split into a training cohort (70%) and a test cohort (30%). Three algorithms were applied for variable selection in the training cohort and logistic models were used to establish a predictive model.

The model demonstrated an AUC of 0.830 (95% CI: 0.775\u20130.884) in the training cohort and 0.759 (95% CI: 0.657\u20130.861) in the test set for predicting MT.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A nomogram combining seven predictive factors may help predict the need for intraoperative MT in patients undergoing LTx to optimize individual transfusion strategies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2026.1786557","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T05:41:43Z","timestamp":1779082903000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Prediction of massive intraoperative blood transfusion requirement in lung transplantation"],"prefix":"10.3389","volume":"13","author":[{"given":"Xinchen","family":"Tao","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ge","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhili","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingcheng","family":"Zou","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingting","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junyu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiuping","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanyuan","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second Affiliated Hospital, Zhejiang University School of Medicine","place":["Hangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,5,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"316","DOI":"10.1097\/TP.0b013e31829853eb","article-title":"Health-related quality of life after solid organ transplantation: a prospective, multiorgan cohort study.","volume":"96","author":"Kugler","year":"2013","journal-title":"Transplantation"},{"key":"B2","doi-asserted-by":"publisher","first-page":"110664","DOI":"10.1016\/j.jclinane.2022.110664","article-title":"Prediction of the severity of acute kidney injury after on-pump cardiac surgery.","volume":"78","author":"Wang","year":"2022","journal-title":"J Clin Anesth"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1060","DOI":"10.1016\/j.healun.2021.07.021","article-title":"The international thoracic organ transplant registry of the international society for heart and lung transplantation: thirty-eighth adult lung transplantation report - 2021;
