We aim to develop a data-based monitoring system for the management of hospitalization days in a regional tertiary hospital of Korea. The contents consisted of 1) development of a monitoring system for days of hospitalization, and 2) development of prediction model for days of hospitalization. The days of hospitalization were monitored and visualized automatically through an interactive R shiny web application. Based on the extracted variables, machine learning models were developed to predict patients hospitalized for more than 7 days, and the XGBoost model showed the best performance with the AUROC of 0.83. Efficient management of hospitalization days is expected by providing the appropriate monitoring system and model.<\/jats:p>","DOI":"10.3233\/shti251303","type":"book-chapter","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:47:52Z","timestamp":1754567272000},"source":"Crossref","is-referenced-by-count":0,"title":["Development of Data-Based Monitoring System for Management of Hospitalization Days in a Regional Tertiary Hospital of Korea"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-7051-8709","authenticated-orcid":false,"given":"Bongjo","family":"Kim","sequence":"first","affiliation":[{"name":"Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1266-5398","authenticated-orcid":false,"given":"Hyeon Ji","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Data Sciences Convergence, Dong-A University Interdisciplinary Program"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2772-8958","authenticated-orcid":false,"given":"Sona","family":"Ha","sequence":"additional","affiliation":[{"name":"Dong-A University College of Medicine, Busan, Republic of Korea"},{"name":"Department of Data Sciences Convergence, Dong-A University Interdisciplinary Program"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2518-6951","authenticated-orcid":false,"given":"In Ho","family":"Kwon","sequence":"additional","affiliation":[{"name":"Dong-A University College of Medicine, Busan, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0047-3102","authenticated-orcid":false,"given":"Minkook","family":"Son","sequence":"additional","affiliation":[{"name":"Dong-A University College of Medicine, Busan, Republic of Korea"},{"name":"Department of Data Sciences Convergence, Dong-A University Interdisciplinary Program"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2025 \u2014 Healthcare Smart \u00d7 Medicine Deep"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI251303","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:47:52Z","timestamp":1754567272000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI251303"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"ISBN":["9781643686080"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti251303","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
