Previous studies suggested higher mortality rate in COVID-19 patients with comorbidities. To our knowledge, most of the published articles focused on clinical characteristics and treatment based on patients\u2019 medical records (EMR). Based on our experience with comorbid hospitalized COVID-19 patients, we argue that HIS administrative data can be used to identify what comorbidities and other factors are associated with hospitalized COVID-19 patients\u2019 mortality and provide a quick initial assessment in view to identifying comorbid individuals that are more prone to worse outcome thus improving patient management not only during pandemics.<\/jats:p>","DOI":"10.3233\/shti250781","type":"book-chapter","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T08:23:26Z","timestamp":1751271806000},"source":"Crossref","is-referenced-by-count":0,"title":["On the Use of HIS Administrative Data to Assess Mortality Among Comorbid Hospitalized Patients \u2013 Lessons Learned from the COVID-19 Pandemic"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9844-5590","authenticated-orcid":false,"given":"Iskra","family":"Mircheva","sequence":"first","affiliation":[{"name":"Medical University \u201cProf. d-r Paraskev Stoyanov\u201d, Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4228-3152","authenticated-orcid":false,"given":"Natalya","family":"Usheva","sequence":"additional","affiliation":[{"name":"Medical University \u201cProf. d-r Paraskev Stoyanov\u201d, Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7819-2976","authenticated-orcid":false,"given":"Martin","family":"Mirchev","sequence":"additional","affiliation":[{"name":"Medical University \u201cProf. d-r Paraskev Stoyanov\u201d, Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana","family":"Kiselkova","sequence":"additional","affiliation":[{"name":"UMHAT St. Marina \u2013 Varna; Department of Medical Activity Reporting and Coding"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Global Healthcare Transformation in the Era of Artificial Intelligence and Informatics"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI250781","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T08:23:27Z","timestamp":1751271807000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI250781"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6,26]]},"ISBN":["9781643686004"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti250781","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,6,26]]}}}
