Characteristics of Markets and Patients Served by ESRD Seamless Care Organizations

Abstract

Under the Comprehensive End-stage Renal Disease (ESRD) Care (CEC) Model, dialysis facilities and nephrologists form ESRD Seamless Care Organizations (ESCOs) to deliver high value care. This study compared the characteristics of patients and markets served and unserved by CEC and assessed its generalizability. ESCOs operated in 65 of 384 markets. ESCO markets were larger than non-ESCO markets, had fewer White patients, higher household income, and higher Medicare spending per patient. Patients in ESCOs were similar to eligible nonaligned patients in age and sex but differed in race/ethnicity and were more often treated in an urban area; comorbidity prevalence differed modestly. CEC is available to a meaningful share of the dialysis population and relatively few dialysis patients resided in a market where no provider could meet the participation threshold, so market size may not be the primary barrier for potential new participants in CEC or future kidney care models.
