The study period extended from January 1, 2010, to December 31, 2019. Data analysis was performed from January 2023 to February 2025.<\/jats:p>\n <\/jats:sec>\n \n Exposure<\/jats:title>\n Medicaid expansion under the ACA.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The primary outcome was 1-year mortality from the date of dialysis initiation. Secondary outcomes were Medicaid coverage, uninsurance, predialysis nephrology care, prescribed hemodialysis duration, modality of dialysis, and catheter use at hemodialysis initiation.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Among 7139 patients in expansion states, 2348 were 14 to 18 years old (1280 male [54.5%]; 1068 female [45.5%]), and 4791 were 19 to 23 years old (2717 male [56.7%]; 2074 female [43.3%]. One-year mortality for 19- to 23-year-olds declined from 3.6% (95% CI, 2.4% to 4.9%) in the pre-expansion period to 2.1% (95% CI, 1.2% to 3.0%) after expansion (change, \u22121.5 percentage points; 95% CI, \u22122.5 to \u22120.6), while for 14- to 18-year-olds, the concurrent mortality rate was 0.7% (95% CI, 0.3% to 1.0%) pre-expansion and 1.1% (95% CI, 0.5% to 1.7%) postexpansion (change, 0.4 percentage points; 95% CI, \u22120.3 to 1.1). The adjusted difference-in-difference estimate was \u22121.8 percentage points (95% CI, \u22122.9 to \u22120.7). Medicaid coverage for 19- to 23-year-olds increased from 37.1% to 48.5% and uninsurance rates declined from 19.4% to 7.8%. After accounting for concurrent changes among 14- to 18-year-olds, the adjusted difference-in-difference estimates were 8.4 percentage points (95% CI, 4.8 to 12.0) for Medicaid and \u22129.1 percentage points (95% CI, \u221212.4 to \u22125.8) for uninsurance. Medicaid expansion was associated with higher rates of predialysis nephrology care, prescribed hemodialysis sessions of 4 or more hours, and use of peritoneal dialysis, but not associated with use of catheters for hemodialysis or kidney transplant rates.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n This study found that Medicaid expansion was associated with reductions in 1-year mortality among young adults with kidney failure initiating dialysis. Policy changes to health insurance programs may affect survival for young adults with this highly morbid condition.<\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamapediatrics.2026.1530","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T15:30:28Z","timestamp":1778513428000},"page":"851","source":"Crossref","is-referenced-by-count":2,"title":["Medicaid Expansion and 1-Year Mortality Among Young Adults Initiating Dialysis"],"prefix":"10.1001","volume":"180","author":[{"given":"Shailender","family":"Swaminathan","sequence":"first","affiliation":[{"name":"Department of Health Services, Policy and Practice, Brown University, Providence, Rhode Island"},{"name":"Sapien Labs Centre for Human Brain and Mind, Chennai, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daeho","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Health Services, Policy and Practice, Brown University, Providence, Rhode Island"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin D.","family":"Sommers","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, Harvard T.H.
