The national costs to the Medicare system were estimated to be $69 275 429 (95% CI, $63 010 840-$76 315 210) for ED visits and $191 409 579 (95% CI, $172 782 870-$206 181 300) for hospitalizations. Stratified analyses highlighted greater impacts for certain demographic groups, including adults older than 85 years, and specific seasonal patterns.</p><p><strong>Conclusions and relevance: </strong>In this cohort study of Medicare beneficiaries 65 years or older, flood exposure was associated with increased health care use and costs, underscoring the need for targeted public health strategies and improved disaster preparedness, especially for older adults. These findings contribute to a more comprehensive understanding of the health-related costs of flooding and can be used to inform future climate change resilience and health care planning.</p>","PeriodicalId":14694,"journal":{"name":"JAMA Network Open","volume":"8 3","pages":"e250371"},"PeriodicalIF":10.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894485/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143584860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
