The cases were divided into survival and mortality groups based on the discharge outcomes. The basic data were collected. A logistic regression model was used to analyze the risk factors for mortality.\nResults: The in-hospital mortality rate was 25.54% (102 survivors, 35 non-survivors). The mean age was higher in the mortality group. Shock and dyspnea were more common in the mortality group (p = 0.041). Multivariable logistic regression analysis concluded that advanced age (odds ratio, (OR) = 2.158, 95% confidence interval (CI): 1.183\u20133.368), shock (OR = 2.876, 95% CI: 1.538\u20138.304), high neutrophil-to-lymphocyte ratio (NLR; OR = 1.872, 95% CI: 1.060\u20132.424), radiographic pleural effusion (OR = 1.756, 95% CI: 1.592\u20133.662), and elevated fasting glucose (OR = 1.785, 95% CI: 1.263\u20133.821) were independent predictors of in-hospital mortality. The Hosmer\u2013Lemeshow test showed that the proposed model had a good fit with observed values (\u03c72 = 4.681, p = 0.341). The receiver operating characteristic curve indicated that the proposed model had an area under the curve of 0.791 for predicting mortality, with a sensitivity of 83.9% and specificity of 61.5%.\nConclusions: The in-hospital mortality rates were high in elderly patients with Omicron infection. Advanced age, glucose level, shock, NLR, and pleural effusion were identified as risk factors.<\/jats:p>","DOI":"10.3855\/jidc.20747","type":"journal-article","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T18:26:27Z","timestamp":1772821587000},"page":"153-159","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of in-hospital mortality and associated risk factors in hospitalized elderly patients with an Omicron infection"],"prefix":"10.3855","volume":"20","author":[{"given":"Yan","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya-Nan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Tong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Cao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2222","published-online":{"date-parts":[[2026,2,28]]},"container-title":["The Journal of Infection in Developing Countries"],"original-title":[],"link":[{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/20747\/3819","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/20747\/3819","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T18:26:27Z","timestamp":1772821587000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/view\/20747"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,28]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2026,2,28]]}},"URL":"https:\/\/doi.org\/10.3855\/jidc.20747","relation":{},"ISSN":["1972-2680"],"issn-type":[{"value":"1972-2680","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,28]]}}}
