Effect of Medicare dialysis payment reform on use of erythropoiesis stimulating agents.
Ontology highlight
ABSTRACT: Objective
In 2011, the Centers for Medicare and Medicaid Services (CMS) replaced fee-for-service reimbursement for erythropoiesis stimulating agents (ESAs) with a fixed-sum bundled payment for all dialysis-related care and pay-for-performance incentives to discourage maintaining patients' hematocrits above 36 percent. We examined the impact of the new payment policy on the use of ESAs.Data sources
CMS's Renal Information Management System.Study design
Regression discontinuity design assessing the use of ESAs by hematocrit level before and after the implementation of the payment policy change.Data extraction
Secondary data from 424,163 patients receiving hemodialysis treatment between January 2009 and June 2011.Principal findings
The introduction of bundled payments with pay-for-performance initiatives was associated with an immediate and substantial decline in the use of ESAs among patients with hematocrit >36 percent and little change in the use of ESAs among patients with hematocrit ≤36 percent. In the first two quarters of 2011, the use of ESAs during dialysis fell by about 7-9 percentage points among patients with hematocrit levels >36 percent. No statistically significant differences in ESA use were observed at the thresholds of 30 or 33 percent.Conclusions
CMS's payment reform for dialysis care reduced the use of ESAs in patients who may not benefit from these agents.

Project description:Background and objectives: Peritoneal dialysis (PD) for ESKD is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis (HD), but has historically been underused. We assessed the effect of the 2011 Medicare prospective payment system (PPS) for dialysis on PD initiation, modality switches, and stable PD use.Design, setting, participants, & measurements: Using US Renal Data System and Medicare data, we identified all United States patients with ESKD initiating dialysis before (2006-2010) and after (2011-2013) PPS implementation, and observed their modality for up to 2 years after dialysis initiation. Using logistic regression models, we examined the associations between PPS and early PD experience (any PD 1-90 days after initiation), late PD use (any PD 91-730 days after initiation), and modality switches (PD-to-HD or HD-to-PD 91-730 days after initiation). We adjusted for patient, dialysis facility, and regional characteristics.Results: Overall, 619,126 patients with incident ESKD received dialysis at Medicare-certified facilities, 2006-2013. Observed early PD experience increased from 9.4% before PPS to 12.6% after PPS. Observed late PD use increased from 12.1% to 16.1%. In adjusted analyses, PPS was associated with increased early PD experience (odds ratio [OR], 1.51; 95% confidence interval [95% CI], 1.47 to 1.55; P<0.001) and late PD use (OR, 1.47; 95% CI, 1.45 to 1.50; P<0.001). In subgroup analyses, late PD use increased in part due to an increase in HD-to-PD switches among those without early PD experience (OR, 1.59; 95% CI, 1.52 to 1.66; P<0.001) and a decrease in PD-to-HD switches among those with early PD experience (OR, 0.92; 95% CI, 0.87 to 0.98; P=0.004).Conclusions: More patients started, stayed on, and switched to PD after dialysis payment reform. This occurred without a substantial increase in transfers to HD.

Project description:ObjectiveTo evaluate the effect of the Medicare dialysis payment reform on potential disparities in the selection of peritoneal dialysis (PD) for the treatment of end-stage renal disease (ESRD).Data sourcesCenters for Medicare & Medicaid Services (CMS) ESRD Medical Evidence Form, Medicare claims, and other CMS data for 2008-2013.Study designWe examined the association of patient age, race/ethnicity, urban/rural location, pre-ESRD care, comorbidities, insurance, and other factors with the selection of PD as initial dialysis modality across prereform (2008-2009), interim (2010), and postreform (2011-2013) time periods.Principal findingsSelection of PD increased among diverse patient subgroups following the payment reform. However, the lower PD selection observed with older age, black race, Hispanic ethnicity, less pre-ESRD care, and Medicaid insurance before the reform largely remained in the initial postreform years.ConclusionsDespite recent growth in PD, there may be ongoing disparities in access to PD that have largely not been mitigated by the payment reform. There is potential for modifying provider financial incentives to achieve policy goals related to cost and quality of care. However, even with a substantial shift in financial incentives, separate initiatives to reduce existing disparities in care may be needed.

Project description:INTRODUCTION: Erythropoiesis-Stimulating Agents (ESA) are hypothesized to increase cardiovascular mortality in patients with chronic kidney disease. One of the proposed mechanisms is the elevation of blood pressure (BP) by ESA. Therefore, we aimed to determine whether the use of ESA was associated with antihypertensive treatment and higher BP. MATERIALS AND METHODS: In this cohort 502 incident pre-dialysis patients were included who started specialized pre-dialysis care in 25 clinics in the Netherlands. Data on medication including ESA use and dose, co-morbidities and BP were routinely collected every 6 months. Antihypertensive treatment and BP were compared for patients with and without ESA at baseline. Differences in antihypertensive medication and BP during pre-dialysis care were estimated with linear mixed models adjusted for age, sex, body mass index, cardiovascular disease, diabetes mellitus and estimated glomerular filtration rate. RESULTS: At baseline, 95.6% of patients with ESA were treated with antihypertensive medication and 73.1% of patients without ESA. No relevant difference in BP was found. During pre-dialysis care patients with ESA used 0.77 (95% CI 0.63;0.91) more classes of antihypertensive drugs. The adjusted difference in systolic blood pressure (SBP) was -0.3 (95% CI -2.7;2.0) mmHg and in diastolic blood pressure (DBP) was -1.0 (95% CI -2.1;0.3) mmHg for patients with ESA compared to patients without ESA. Adjusted SBP was 3.7 (95% CI -1.6;9.0) mmHg higher in patients with a high ESA dose compared to patients with a low ESA dose. CONCLUSIONS: Our study confirms the hypertensive effect of ESA, since ESA treated patients received more antihypertensive agents. However, no relevant difference in BP was found between patients with and without ESA, thus the increase in BP seems to be controlled for by antihypertensive medication.

Project description:BackgroundErythropoiesis-stimulating agents (erythropoietin and darbepoietin) have been approved to reduce the number of blood transfusions required during chemotherapy; however, concerns about the risks of venous thromboembolism and mortality exist.MethodsWe identified patients who were aged 65 years or older in the Surveillance, Epidemiology, and End Results-Medicare database; who were diagnosed with colon, non-small cell lung, or breast cancer or with diffuse large B-cell lymphoma from January 1, 1991, through December 31, 2002; and who received chemotherapy. The main outcome measures were claims for use of an erythropoiesis-stimulating agent, blood transfusion, venous thromboembolism (ie, deep vein thrombosis or pulmonary embolism), and overall survival. We used multivariable logistic regression models to analyze the association of erythropoiesis-stimulating agent use with clinical and demographic variables. We used time-dependent Cox proportional hazards models to analyze the association of time to receipt of first erythropoiesis-stimulating agent with venous thromboembolism and overall survival. All statistical tests were two-sided.ResultsAmong 56,210 patients treated with chemotherapy from 1991 through 2002, 15,346 (27%) received an erythropoiesis-stimulating agent. The proportion of patients receiving erythropoiesis-stimulating agents increased from 4.8% in 1991 to 45.9% in 2002 (P < .001). Use was associated with more recent diagnosis, younger age, urban residence, comorbidities, receipt of radiation therapy, female sex, and metastatic or recurrent cancer. The rate of blood transfusion per year during 1991-2002 remained constant at 22%. Venous thromboembolism developed in 1796 (14.3%) of the 12,522 patients who received erythropoiesis-stimulating agent and 3400 (9.8%) of the 34,820 patients who did not (hazard ratio = 1.93, 95% confidence interval = 1.79 to 2.07). Overall survival was similar in both groups.ConclusionUse of erythropoiesis-stimulating agent increased rapidly after its approval in 1991, but the blood transfusion rate did not change. Use of erythropoiesis-stimulating agents was associated with an increased risk of venous thromboembolism but not of mortality.

Project description:BACKGROUND:In 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. METHODS:To 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. RESULTS:Dialysis 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. CONCLUSIONS:Expansion 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.

Project description:IntroductionSeveral jurisdictions have adopted a more conservative approach to anemia in patients receiving dialysis amid safety concerns from target hemoglobin studies. It is largely unknown if this has contributed to a change in clinical outcomes.MethodsA national registry was used to identify 35,945 adult patients who initiated and were maintained on dialysis for ≥90 days in Canada from January 2007 to December 2015. Outcomes were ascertained until March 2017 via linkage with hospital discharge diagnoses. Cox proportional hazards models were used to investigate the association between the era of dialysis initiation and the primary composite outcome (acute myocardial infarction [AMI], stroke, or mortality).ResultsThe mean hemoglobin at dialysis initiation decreased from 102.9 g/l in 2007 to 95.5 g/l in 2015, corresponding with a higher prevalence of hemoglobin <80 g/l (8% to 17%) and a reduction in erythropoiesis stimulating agent (ESA) use (49% to 44%). After multivariable adjustment, Era 3 (2013-2015) was associated with an 8% relative risk reduction in the primary outcome compared with Era 1 (2007-2009) (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.88-0.96), a 10% relative reduction in mortality (HR 0.90, 95% CI 0.85-0.94) but no significant change in AMI or stroke. In a model without era, neither hemoglobin nor ESA use was an independent predictor of outcome.ConclusionThere have been modest declines in average hemoglobin values and ESA use among incident dialysis patients in Canada with no change in major cardiovascular outcomes. Patient survival has improved over time, likely for reasons other than anemia management.

Project description:OBJECTIVE:To evaluate the 2019 Medicare Physician Fee Schedule, which modifies reimbursement for office evaluation and management (E&M) visits. This policy moves payment to a single rate for levels 2 through 4 office E&M visits, regardless of complexity. METHODS:Using a 20% sample of 2015 National Medicare claims, we identified urologic practices and their practice organization, academic affiliation, and degree of office focus (ie, proportion of revenues from office visits). Using billing data for each practice, we calculated the revenues expected under the current system and the new policy (both E&M payments and a new add-on code). For each practice, we determined the impact of new payment rates on total Medicare payments. RESULTS:We identified 2822 practices: 1372 (48.6%) solo practices, 1033 (36.6%) multispecialty groups, 322 (11.4%) small urology groups, and 95 (3.4%) large urology groups. Under the new reimbursement rates, the median practice would have a 0.9% increase in Medicare Part B payments (range -20.4% to +50.3%) and, with the add-on code, an increase of 6.8% (range -7.5% to +74.9%). Solo practices had the most heterogeneity, with a quarter losing at least 2.3%. The median multispecialty group would increase payments by 0.4% (range -13.7% to 50.3%). However, the 107 (10.4%) academic multispecialty groups had a median gain of only 0.1% (range -2.8% to +8.1%). CONCLUSION:Urology groups would, on average, benefit from the anticipated change in Medicare office E&M visit payments. However, solo practices with a high office focus and academic multispecialty practices may see reduced Medicare payments.

Project description:OBJECTIVES:Patients with end-stage renal disease can receive dialysis at home or in-center. In 2004, CMS reformed physician payment for in-center hemodialysis care from a capitated to a tiered fee-for-service model, augmenting physician payment for frequent in-center visits. We evaluated whether payment reform influenced dialysis modality assignment. STUDY DESIGN:Cohort study of patients starting dialysis in the United States in the 3 years before and the 3 years after payment reform. METHODS:We conducted difference-in-difference analyses comparing patients with traditional Medicare coverage (who were affected by the policy) to others with Medicare Advantage (who were unaffected by the policy). We also examined whether the policy had a more pronounced influence on dialysis modality assignment in areas with lower costs of traveling to dialysis facilities. RESULTS:Patients with traditional Medicare coverage experienced a 0.7% (95% CI, 0.2%-1.1%; P = .003) reduction in the absolute probability of home dialysis use following payment reform compared with patients with Medicare Advantage. Patients living in areas with larger dialysis facilities (where payment reform made in-center hemodialysis comparatively more lucrative for physicians) experienced a 0.9% (95% CI, 0.5%-1.4%; P < .001) reduction in home dialysis use following payment reform compared with patients living in areas with smaller facilities (where payment reform made in-center hemodialysis comparatively less lucrative for physicians). CONCLUSIONS:The transition from a capitated to a tiered fee-for-service payment model for in-center hemodialysis care resulted in fewer patients receiving home dialysis. This area of policy failure highlights the importance of considering unintended consequences of future physician payment reform efforts.

Project description:BackgroundSeveral studies have shown an association between erythropoietin-stimulating agent (ESA) responsiveness and mortality in chronic kidney disease (CKD) patients. In our present study, we examined the association between prescribed ESA dose and mortality in peritoneal dialysis (PD) and hemodialysis (HD) patients. We hypothesized that PD patients received lower ESA dose for the same achieved hemoglobin compared to HD patients and that ESA dose-mortality associations were different between PD and HD patients.MethodsWe compared the prescribed doses of ESA between 139,103 HD and 10,527 PD patients treated in DaVita dialysis clinics from 7/2001 through 6/2006 using adjusted Poisson regression and examined mortality-predictability of prescribed ESA dose and ESA responsiveness index (ESA/hemoglobin) in PD and HD with follow-up through 6/2007 using Cox regression models.ResultsPoisson adjusted ratio of ESA dose of HD to PD was 3.6 (95% CI 3.5-3.7). In PD patients, adjusted all-cause death hazard ratios (HR) for ESA doses of 3,000-5,999, 6,000-8,999 and ?9,000 U/week (reference <3,000 U/week) were 0.97 (0.87-1.07), 0.85 (0.76-0.95) and 1.08 (0.98-1.18), respectively; whereas in HD patients across commensurate ESA dose increments of 10,000-19,999, 20,000-29,999 and ?30,000 U/week (reference <10,000 U/week) were 1.14 (1.11-1.17), 1.54 (1.50-1.58) and 2.15 (2.10-2.21), respectively. In PD and HD patients, the adjusted death HR of the 4th to 1st quartile of ESA responsiveness index were 1.14 (1.04-1.26) and 2.37 (2.31-2.43), respectively.ConclusionsBetween 2001 and 2006, most PD patients received substantially lower ESA dose for same achieved hemoglobin levels, and low ESA responsiveness was associated with higher mortality in both HD and PD patients.

Project description:Erythropoiesis-stimulating agents (ESAs) are commonly used to treat anemia in patients with CKD, including those receiving dialysis, although clinical trials have identified risks associated with ESA use. We evaluated the effects of changes in dialysis payment policies and product labeling instituted in 2011 on mortality and major cardiovascular events across the United States dialysis population in an open cohort study of patients on dialysis from January 1, 2005, through December 31, 2012, with Medicare as primary payer. We compared observed rates of death and major cardiovascular events in 2011 and 2012 with expected rates calculated on the basis of rates in 2005-2010, accounting for differences in patient characteristics and influenza virulence. An abrupt decline in erythropoietin dosing and hemoglobin concentration began in late 2010. Observed rates of all-cause mortality, cardiovascular mortality, and myocardial infarction in 2011 and 2012 were consistent with expected rates. During 2012, observed rates of stroke, venous thromboembolic disease (VTE), and heart failure were lower than expected (absolute deviation from trend per 100 patient-years [95% confidence interval]: -0.24 [-0.08 to -0.37] for stroke, -2.43 [-1.35 to -3.70] for VTE, and -0.77 [-0.28 to -1.27] for heart failure), although non-ESA-related changes in practice and Medicare payment penalties for rehospitalization may have confounded the results. This initial evidence suggests that action taken to mitigate risks associated with ESA use and changes in payment policy did not result in a relative increase in death or major cardiovascular events and may reflect improvements in stroke, VTE, and heart failure.
