Emergency department (ED) visits at end-of-life may cause financial strain and serve as a marker of inadequate access to community services and health care. We sought to examine end-of-life ED use, total healthcare spending, and out-of-pocket spending in a nationally representative sample. Using Medicare Current Beneficiary Survey data, we conducted a pooled cross-sectional analysis of Medicare beneficiaries aged 65+ years with a date of death between July 1, 2015 and December 31, 2021. Our primary outcomes were ED visits, total healthcare spending, and out-of-pocket spending in the 7, 30, 90, and 180 days preceding death. We estimated a series of zero-inflated negative binomial models identifying patient characteristics associated with the primary outcomes. Among 3812 older adult decedents, 610 (16%), 1207 (31.7%), 1582 (41.5%), and 1787 (46.9%) Medicare beneficiaries had ED visits in the final 7, 30, 90, and 180 days, respectively, of life. For Medicare beneficiaries with at least one ED visit in the final 30 days of life, the median total and out-of-pocket costs were, respectively, $12,500 and $308, compared, respectively, with $278 and $94 for those without any ED visits (p < 0.001 for both comparisons). Having a diagnosis of dementia (odds ratio [OR] 0.71; 95% confidence interval [CI] 0.51-0.99; p = 0.04) and being on hospice status during the year of death (OR 0.56; 95% CI 0.48-0.66; p = <0.001) were associated with a decreased likelihood of having an ED visit. Having dementia was associated with a decreased likelihood of having any healthcare spending (OR 0.50; 95% CI 0.36-0.71; p = 0.001) and any out-of-pocket spending (OR 0.51; 95% CI 0.36-0.72; p = <0.001). One in three older adults visit the ED in the last month of life, and approximately one in two utilize ED services in the last half-year of life, with evidence of associated considerable total and out-of-pocket spending.
