However, limited data are available on the long\u2010term survival and evolving care needs of older patients with COVID\u201019 in Japan. We evaluated 1\u2010year survival rates and long\u2010term care needs in this vulnerable population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This population\u2010based cohort study analyzed 2175 hospitalized patients with COVID\u201019 aged \u2265\u200965\u2009years using data from the Nara Kokuho Database between February 2020 and August 2022. The database contains administrative claims data from the National Health Insurance and Late Elders' Health Insurance systems, incorporating information on care needs levels. We examined 1\u2010year survival and changes in care needs levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The overall 1\u2010year survival rate was 80.9%. Age significantly influenced survival, with rates of 93.6% for patients aged 65\u201369\u2009years and 56.6% for those \u2265\u200990\u2009years. Disease severity had a substantial impact: patients not requiring oxygen therapy had a survival rate of 87.5%, compared to 74.0% for those with supplemental oxygen and 49.9% for those receiving invasive mechanical ventilation. Despite a decline in severe cases following the Delta and Omicron\u2010predominant waves, survival among severely ill patients remained lower. While most patients without prior care needs retained independence, approximately 23% developed new care requirements after COVID\u201019. Higher care needs levels were associated with significantly higher mortality, with patients at care needs level \u2265\u20092 experiencing mortality rates exceeding 35%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study highlights the importance of comprehensive management of the long\u2010term survival and care needs of older patients with COVID\u201019.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ggi.70353","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T07:30:08Z","timestamp":1769758208000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["One\u2010Year Survival and Changes in Care Needs Among Hospitalized Older Patients With Coronavirus Disease 2019 in Japan: A Nara Kokuho Database Analysis"],"prefix":"10.1111","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8072-6298","authenticated-orcid":false,"given":"Kiyoshi","family":"Takemoto","sequence":"first","affiliation":[{"name":"Department of Public Health Health Management and Policy, Nara Medical University  Kashihara Nara Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3820-6157","authenticated-orcid":false,"given":"Tomoya","family":"Myojin","sequence":"additional","affiliation":[{"name":"Department of Community Health and Preventive Medicine Hamamatsu University School of Medicine  Hamamatsu Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1956-3925","authenticated-orcid":false,"given":"Yuichi","family":"Nishioka","sequence":"additional","affiliation":[{"name":"Department of Public Health Health Management and Policy, Nara Medical University  Kashihara Nara Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8198-2140","authenticated-orcid":false,"given":"Ikko","family":"Yamazaki","sequence":"additional","affiliation":[{"name":"Department of Public Health Health Management and Policy, Nara Medical University  Kashihara Nara Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3652-7547","authenticated-orcid":false,"given":"Tatsuya","family":"Noda","sequence":"additional","affiliation":[{"name":"Department of Public Health Informatics Kansai Medical University  Hirakata Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1981-9959","authenticated-orcid":false,"given":"Tomoaki","family":"Imamura","sequence":"additional","affiliation":[{"name":"Department of Public Health Health Management and Policy, Nara Medical University  Kashihara Nara Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(21)02143-7"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiaa767"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmii.2022.10.003"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.9778\/cmajo.20200213"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiab515"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph20206926"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-024-09131-4"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10112477"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.35772\/ghm.2022.01015"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12955-022-02033-6"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.14326\/abe.11.203"},{"key":"e_1_2_12_13_1","unstructured":"Clinical Management of Patients With COVID\u201019: A Guide for Front\u2010Line Healthcare Workers: Version 2.1 2020."},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/22221751.2022.2155250"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000005822"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13613-021-00959-6"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-021-11879-2"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2005.53175.x"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/ggi.13777"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcmm.17747"},{"key":"e_1_2_12_21_1","doi-asserted-by":"crossref","unstructured":"A.Fall R.
