BackgroundIn 2011, inclusion of injectable medications into an expanded ESKD payment bundle prompted concerns that dialysis facilities facing higher costs might close, disrupting care delivery and access to care. Whether this policy change influenced dialysis facility closures is unknown.MethodsTo examine whether facility closures increased after 2011 and whether factors influencing closures changed, we analyzed US Renal Data System registry data to identify all patients receiving in-center hemodialysis from 2006 through 2015 and to track dialysis facility closures. We used interrupted time series logistic regression models and estimated marginal effects to examine immediate and longer-term changes in the likelihood of being affected by facility closures following payment reform. We also examined whether associations between selected predictors of closures indicating populations at "high risk" of closure (patient characteristics, facility characteristics, and geography-related characteristics) and closures changed after payment reform.ResultsDialysis facility closures were uncommon over the study period. In adjusted models, the relative odds of experiencing a closure declined by 37% (odds ratio [OR], 0.63; 95% confidence interval [95% CI], 0.59 to 0.67) immediately after payment reform and declined by an additional 6% (OR, 0.94; 95% CI, 0.91 to 0.97) annually thereafter, corresponding to a 0.3% lower absolute probability of closure in 2015 in association with payment reform. Patients who were black and who dialyzed at small, hospital-based facilities experienced slight increases in closures following payment reform, whereas Hispanic and Medicare/Medicaid dual-eligible patients experienced slight decreases in closures.ConclusionsExpansion of the ESKD payment bundle was not associated with increased closure of dialysis facilities, although the likelihood of closures changed slightly for some higher-risk populations.Copyright © 2020 by the American Society of Nephrology.
