Nursing home residents and their proxies respond to quality of care by changing providers, Cox proportional hazards models were estimated using assessment data from the Minimum Data Set. The results provide some reassurance that consumers (or their proxies) reward quality in the market, and that changing care needs may initiate a search for alternative care.

Background: Racial disparities in health care are widespread in the United States. Identifying contributing factors may improve care for underserved minorities. To the extent that differential utilization of services, based on need or biological effect, contributes to outcome disparities, prospective payment systems may require inclusion of race to minimize these adverse effects. This research determines whether costs associated with end-stage renal disease (ESRD) care varied by race and whether this variance affected payments to dialysis facilities. Study Design: We compared the classification of race across Medicare databases and investigated differences in cost of care for long-term dialysis patients by race. Setting & Participants: Medicare ESRD database including 890,776 patient-years in 2004-2006. Predictors: Patient race and ethnicity. Outcomes: Costs associated with ESRD care and estimated payments to dialysis facilities under a prospective payment system. Results: There were inconsistencies in race and ethnicity classification; however, there was significant agreement for classification of black and nonblack race across databases. In predictive models evaluating the cost of outpatient dialysis care for Medicare patients, race is a significant predictor of cost, particularly for cost of separately billed injectable medications used in dialysis. Overall, black patients had 9% higher costs than nonblack patients. In a model that did not adjust for race, other patient characteristics accounted for only 31% of this difference. Limitations: Lack of information about biological causes of the link between race and cost. Conclusions: There is a significant racial difference in the cost of providing dialysis care that is not accounted for by other factors that may be used to adjust payments. This difference has the potential to affect the delivery of care to certain populations. Of note, inclusion of race into a prospective payment system will require better understanding of biological differences in bone and anemia outcomes, as well as effects of inclusion on self-reported race.

Background and Objectives: Peritoneal dialysis (PD) use increased in the United States with the introduction of a new Medicare prospective payment system in January 2011 that likely reduced financial disincentives for facility use of this home therapy. The expansion of PD to a broader population and facilities having less PD experience may have implications for patient outcomes. We assessed the impact of PD expansion on PD discontinuation and patient mortality., Design, Setting, Participants, & Measurements: A prospective cohort study was conducted of patients treated with PD at 90 days of ESKD. Patients were grouped by study start date relative to the Medicare payment reform: prereform (July 1, 2008 to December 31, 2009; n =10,585), interim (January 1, 2010 to December 31, 2010; n =7832), and reform period (January 1, 2011 to December 31, 2012; n =18,742). Patient characteristics and facility PD experience were compared at baseline (day 91 of ESKD). Patients were followed for 3 years for the major outcomes of PD discontinuation and mortality using Cox proportional hazards models., Results: Patient characteristics, including age, sex, race, ethnicity, rurality, cause of ESKD, and comorbidity, were similar or showed small changes across the three study periods. There was an increasing tendency for patients on PD to be treated in facilities with less PD experience (from 34% during the prereform period being treated in facilities averaging <14 patients on PD per year to 44% in the reform period). Patients treated in facilities with less PD experience had a higher rate of PD discontinuation than patients treated in facilities with the most experience (hazard ratio [HR], 1.16; 95% confidence interval [95% CI], 1.10 to 1.23 for the first versus fifth quintile of PD experience). Nevertheless, the risk of PD discontinuation fell during the late interim period (HR, 0.88; 95% CI, 0.82 to 0.95) and most of the reform period (from HR, 0.85; 95% CI, 0.79 to 0.91 to HR, 0.94; 95% CI, 0.87 to 1.01). Mortality risk was stable across the three study periods., Conclusions: In the context of expanding PD use and declining facility PD experience, the risk of PD discontinuation fell, and there was no adverse effect on mortality., Podcast: This article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2019&#95;09&#95;12&#95;CJN01610219.mp3., (Copyright © 2019 by the American Society of Nephrology.)

Implementation of the Medicare ESRD prospective payment system (PPS) and changes to dosing guidelines for erythropoiesis-stimulating agents (ESAs) in 2011 appear to have influenced use of injectable medications among dialysis patients. Given historically higher ESA and vitamin D use among black patients, we assessed the effect of these policy changes on racial disparities in the management of anemia and mineral metabolism. Analyses used cross-sectional monthly cohorts for a period-prevalent sample of 7384 maintenance hemodialysis patients at 132 facilities from the Dialysis Outcomes and Practice Patterns Study (DOPPS) Practice Monitor. Linear splines with knots at each policy change were used in survey-weighted regressions to estimate time trends in hemoglobin (Hgb), erythropoietin (EPO) dose, intravenous (IV) iron dose, ferritin, transferrin saturation (TSAT) concentration, parathyroid hormone (PTH), IV vitamin D dose, cinacalcet use, and phosphate binder use. From August 2010 to December 2011, mean Hgb declined from 11.5 to 11.0 g/dl (P<0.001), mean EPO dose declined from 20,506 to 14,777 U/wk (P<0.001), and mean serum PTH increased from 340 to 435 pg/ml (P<0.001). No meaningful differences by race were observed regarding the rates of change of management practices or laboratory measures (all P>0.21). Mean EPO and vitamin D dose and serum PTH levels remained higher in blacks. Despite evidence that anemia and mineral metabolism management practices have changed significantly over time, there was no immediate indication of racial disparities resulting from implementation of the PPS or ESA label change. Further studies are needed to examine effects among patient and facility subgroups., (Copyright © 2015 by the American Society of Nephrology.)

The Medicare program reimburses dialysis providers a flat rate for a bundle of services that comprise the basic dialysis treatment. This payment system is being modified to incorporate case-mix adjustment for age and body size, which have been shown to influence dialysis costs. This study simulated the economic impact of the recently issued Medicare rule on case-mix adjustment by estimating the variation in payments across patients, facilities, and broad classes of facilities. Case-mix adjustment results in considerable patient-level variation in payments (dollar 12.99 SD in case-mix adjusted payments). The variation across dialysis facilities is smaller but still economically significant (dollar 3.77 SD). However, there was little evidence that particular classes of facilities (e.g., ownership, chain membership, size) will be substantially advantaged or disadvantaged by case-mix adjustment. There do seem to be modest changes in the regional distribution of payments.
