compared to prevalence estimates from other sources, including med-ical charts and administrative claims. Data here illustrate that, for several comorbid conditions, prevalence according to the Medical Evidence Report is 30–50 percent lower than prevalence according to the assess-ment of diagnosis codes in Medicare claims for medical services during the six months before dialysis initia-tion. Plausibly, under-reporting may vary by location and provider orga-nization. These comorbidity desig-nations are used for risk adjustment of several metrics of facility perfor-mance, including standardized mor-tality and hospitalization ratios, and the lack of consistent and compre-hensive reporting may bias metrics—leading, for example, to distortions in star ratings.
Ultimately, these data speak to a much broader issue: many aspects of regulatory oversight, including Dialysis Facility Compare, the Quality Incentive Program, and the 5-Star Quality Rating System, are influenced by the extent to which the Medical Evidence Report is accurately com-pleted, yet those who typically com-plete the form, including nephrolo-gists and nursing staff, have no direct
incentive to verify accurate comple-tion, let alone enough history with the patient to ascertain comorbidity more rigorously than through self-reporting.
The starting point for determining when to initiate dialysis treatment has been based on clinical symptoms and biochemistry. Several studies, how-ever, have shown no benefit in using biochemical criteria to justify starting dialysis at an earlier time. Data here show that the historical trend of rising estimated glomerular filtration rate (eGFR) at dialysis initiation has ceased in recent years. In contrast to the sta-ble landscape surrounding eGFR, the distribution of hemoglobin at dialysis initiation has changed markedly in recent years, with declines in mean hemoglobin due to more limited use of erythropoiesis-stimulating agents (ESAs) in non-dialysis-dependent chronic kidney disease patients.
We conclude this chapter with data regarding initial vascular access. The exceedingly common use of catheters at dialysis initiation is a major concern, and one that dialysis providers would like to address. However, these provid-ers do not treat patients prior to the onset of ESRD. Data from 2011 do indi-cate increased placement of maturing fistulas, but progress is modest.
Further changes must be tracked closely, as the structure of the ESRD Prospective Payment System forces providers to limit costs per treat-ment. Catheter use has been shown in many studies to increase the use of ESAs, likely as a result of increased risk of infectious complications, which themselves might engender hospi-talizations that necessarily result in missed outpatient dialysis treatments. Hopefully, these pressures lead pro-viders to work more closely with phy-sicians to reduce the use of catheters and, in particular, to remove catheters as soon as possible when their use has been acutely required.

E X E C U T I V E S U M M A R YThe Peer Kidney Care Initiative is the result of collaboration among the Chief Medical Officers (cmOs) of thirteen dialysis provider organiza-tions in the United States, including all of the ten largest organizations, according to number of patients treated. The overarching emphases of Peer are on the ways by which provider organizations are addressing the challenges of mortality, morbidity, quality of life, and patient satisfaction, both collaboratively and within each provider organization, and on how provider organizations can learn from one another through examination of available data, all with the goal of advancing patient care. Objectivity is an important aim of Peer, with foci on the successes in the industry and on directions for improvement.
The first meeting of the CMOs was held in Chicago in March 2013, and organized by DaVita HealthCare Partners, Dialysis Clinic, Inc. (DCI), Fresenius Medical Care, and Renal Ventures Management, with Tom F. Parker III, MD, and Doug Johnson,MD, providing the initial structure.This was entirely a clinical meeting,attended by those involved daily inpatient care issues. Material waspresented on the morbidity asso-ciated with fluid overload and leftventricular hypertrophy, as well ason infectious complications, suddencardiac death, catheters for vascularaccess, and other topics affectingoutcomes. Members of the group
shared information on the differ-ent approaches used by each dialysis provider to address these and other clinical challenges.
The second meeting of the CMOs was held in Baltimore in March 2014. Participants described their efforts during the prior year and discussed new directions to further address fluid overload and congestive heart failure, infectious complications, sud-den cardiac death, dialysis bath com-position, and reduction of readmis-sion rates. The predominant feeling was that traditional quality measures are insufficient tools for achieving desired improvements. Members of the group began considering a

Tracking new cases of end-stage renal disease (ESrD) is challenging, because only patients who receive treatment for ESrD are reliably identified by the cmS ESrD Medical Evidence Report (form cmS-2728). Because there is no comprehensive registration system, patients with ESrD who choose not to initiate chronic dialysis are uncounted.
In this section we report on new ESRD patients in freestanding dialysis facili-ties, which provide the vast majority of dialysis treatments in the U.S. This does undercount the total number of new ESRD cases in the U.S., as we are not reporting new patients in hospital-based dialysis facilities (these patients pose an analytic challenge, with respect to the provision of inpa-tient versus outpatient dialysis, which we will address in the coming year) or new patients who immediately receive a kidney transplant. We begin with a flowchart that identifies this subset of new ESRD cases in 2011, and subsequently illustrate incident rates and counts, overall, by U.S. Census Division and by state. While incident rates have begun to decline, there is considerable geographic variation in the absolute burden of ESRD, with important implications for the capac-ity to deliver care.
Like the rates of hospitalization and mortality illustrated in subse-quent chapters, counts of new ESRD
patients vary in a cyclical manner, with the highest counts occurring in the winter and the lowest in the summer. This pattern was reported in Okinawa, Japan, in 1996 (Iseki et al, American Journal of Nephrology) and is clearly present in domestic data as well. As shown in trends by Census Division and state, the slowing of both rates and counts has been far from uniform across the country. Growth in counts continues, for example, in the Middle Atlantic Division, at 3.1 percent per year since 2004. Within the divi-sion, however, the corresponding rate of growth was 4.7 percent per year in New York, but only 1.3 percent per year in Pennsylvania.
Nephrologist care prior to dialy-sis initiation has been tracked for more than a decade through ques-tions in the Medical Evidence Report. Differences by Census Division are quite striking, with 80 percent of new patients in New England receiving pre-ESRD nephrologist care, compared to just 62 percent in the West South
Central Division. These geographic variations deserve greater attention from the physician community, as dialysis providers do not influence referral to a nephrologist prior to the start of dialysis treatment. The CKD education benefit, which became available to Medicare beneficiaries in January 2010, has been used by fewer than 2 percent of new ESRD patients (2013 USRDS ADR, page 117). This is a major concern, as poor preparation for ESRD has been reported to impact patient survival and access to home dialytic modalities. Interestingly, data from Medicare claims paint a more complex picture of nephrolo-gist care prior to dialysis initiation. Some patients appear to have seen a nephrologist only in the inpatient setting, and even in the outpatient setting, a substantial share of patients have only seen a nephrologist once or twice during the six months before dialysis initiation. These findings suggest that data from the Medical Evidence Report may overstate the progress that has been made.
The reporting of comorbidity at dialysis initiation has been a core part of the Medical Evidence Report since 1995. Several studies have noted under-reporting of comorbidity

AverAge monthly counts of incident patients ini-tiating on dialysis in freestanding facilities rose steadily between 1996 and 2010, reaching a peak of more than 8,000 patients per month in 2009 and 2010. In 2011 the average monthly count actually declined, albeit by only slightly more than 1 percent. While it is uncertain whether this decline might represent an aberration due to recent economic weakness or portend a downturn in the inci-dence of Stage 5 CKD, the increasing age of the U.S. popu-lation, and the rising prevalence of diabetes, suggests the former is more likely.
Interestingly, average monthly counts of incident patients exhibit substantial seasonality, with those during the first quarter of recent years exceeding those during the third quarter by roughly 15 percent. This pattern may be due to broadly increased use of healthcare resources during the winter season, resulting in the detection of previously undiagnosed Stage 5 CKD. That more patients begin dialy-sis during the first quarter, a period marked by substantial risk of communicable disease, will be an ongoing challenge for dialysis providers.

nephrologist care, 30 percent began therapy with a maturing fistula and 50 percent had a mature fistula— a rate five times greater than that seen among non-referred patients.
The percentage of patients receiving an erythropoiesis stimulating agent (ESA) prior to initiation continues to change, from 33 percent in September, 2002 to 18.1 percent in 2011. This may reflect concern over potential adverse events when hemoglobin levels are targeted to a level above 11 g/dl. The mean hemoglobin at initiation of ESRD treatment also continues to change, and was 9.63 g/dl at the end of 2011. These changes place different demands on care after the initiation of dialysis. The current FDA rec-ommendations indicate that “In controlled trials, patients experienced greater risks for death, serious adverse cardio-vascular reactions, and stroke when administered eryth-ropoiesis-stimulating agents (ESAs) to target a hemoglo-bin level of greater than 11 g/dL.” “No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks.” The FDA recommends that clinicians “Use the lowest dose that will maintain a hemoglobin level sufficient to reduce the need for RBC transfusions.”
The percentage of dialysis patients beginning therapy with an estimated glomerular filtration rate (eGFR, calcu-lated with the CKD-EPI formula) above 15 ml/min/1.73 m2 fell in 2011, to 15.3 percent — still, however, almost three times higher than in 1996. It is not clear if the generally progressive increase has been the result of severe comor-bidity or of a simple numerical starting point based on the ability to calculate the eGFR. Concerns have recently been
raised about the usefulness of eGFR at ESRD initiation, as the lower serum creatinine used to calculate the rate may be impacted by low muscle mass in older, frail patients. Hopefully, symptoms and complications of uremia are still the primary indications for starting renal replacement therapy rather than a simple number, one which has been brought into question in recent years in controlled trials of early versus later dialysis initiation.
Biochemical data, collected on the Medical Evidence form since 2005, show that 57 percent of new patients in 2011 had an albumin less than the lower limit of normal, and the mean hemoglobin at initiation was9.7 g/dl. Total cholesterol was greater than 200 mg/dl in 16 percent of patients, while 28 percent had an LDL level greater than 100 mg/dl, and 56 percent had an HDL level less than 40 mg/dl. Among patients with diabetes, 29 percent had a hemoglobin A1c level greater than 7 percent.
Recent changes and new incentives in the bundled Prospective Payment System for dialysis patients, intro-duced in January, 2011, may alter several characteristics of the incident and prevalent populations. The mix of peritoneal dialysis and hemodialysis patients, for example, has clearly changed. It is unclear how the expansion of peritoneal dialysis will affect patient outcomes, and how the new incentives will impact the emerging daily home hemodialysis population; provider incentives for this therapy are less clear, particularly as related to training. A more detailed assessment of the bundled payment system is presented in Chapter Ten. • Figure 1.1; see page 430 for analytical methods.

1.7 Incident counts & adjusted rates of ESRD, by primary diagnosis
1.4 Incident counts & adjusted rates of ESRD, by age
1.6 Incident counts & adjusted rates of ESRD, by Hispanic ethnicity
Since 2000, the adjusted incident rate of ESRD has grown 7.1 percent for patients age 75 and older, to 1,707 per million population in 2011, while rates for those age 0–19 and 20–44 have increased 10.1 and 4.1 percent, respectively, to 15.6 and 127. Rates for patients age 45–64 and 65–74, in contrast, though rising slightly during the decade, are now 8.1–8.3 percent lower than in 2000, at 571 and 1,307 per million, respectively.
By race, rates for blacks/African Americans and Native Americans in 2011 were 940 and 453 per million population, respectively — 3.4 and 1.6 times greater than the rate of 280 found among whites. After rising in the middle of the decade, rates for both whites and Asians are now near the levels seen in 2000, while rates for blacks/African Americans and Native Americans are now 10.2 and 36 percent lower.
Fourteen percent of new ESRD patients in 2011 were Hispanic, up from 12.6 percent in 2007. While the rate of ESRD among Hispanics fell 3.0 percent between 2010 and 2011, to 518, it remains 1.5 times greater than that seen in the non-Hispanic population.
At 157 per million population in 2011, the rate of new ESRD cases due to dia-betes is 4.2 percent lower than in the previous year, and has now fallen back to a level not seen since 1998. The rate of ESRD due to hypertension, while down 4.9 percent in 2011, is 2.6 percent higher than the 2000 rate, at 101, while the rate of ESRD due to glomerulonephritis has fallen 29 percent, to 23 per million. • Figures 1.4–7; see page 430 for ana-lytical methods.

in 2011, the number of new patients starting therapy on hemodialysis declined 1.5 percent, the first decrease in more than three decades. The population initiating on peritoneal dialysis, in contrast, grew for the
third year in a row, and now accounts for 6.6 percent of patients with a known dialysis modality. This change is associated with the new bundled payment system, with its clear incentives for peritoneal dialysis. The number of total incident dialysis patients was 112,788, while 2,855 patients received a preemptive transplant as their first ESRD modality; a total of 115,643 patients thus began ESRD therapy in 2011 — a level below that of the two prior years.
The rate of new ESRD cases per million population, relatively stable since 2000, fell 3.8 percent in 2011, to 357. Growth in counts and rates has dropped across all age groups, though, as late reporting of cases can cause slight changes in the numbers, this finding needs to be confirmed in coming years.
The incidence of ESRD in the black/African American population has been declining for the last five years. The rate also continues to fall among Native Americans, reaching a level just 13.5 percent higher than that in the Asian population — the smallest difference in more than three decades. By cause, rates of incident ESRD have fallen across each of the major primary diagnoses: diabetes, hypertension, glomerulonephritis, and cystic diseases. Among those whose ESRD is caused by diabetes, however, racial disparities persist, particularly among younger blacks/African Americans.
The December 31, 2011 prevalent population included 430,273 patients on dialysis and 185,626 patients with a functioning kidney transplant, and the one-year growth of 3.4 percent — to 615,899 — was the smallest in 30 years. The rate of prevalent ESRD cases per million population reached 1,901, an increase of 1.3 percent from 2010, and also the slowest growth in the last three decades. The number of patients receiving home hemodialysis continued to grow, though at a slower pace in 2011.
Insurance coverage in the dialysis population continues to change, with more incident dialysis patients now covered by Medicare Advantage. Private insurance, in contrast, is dominant among patients who receive a preemp-tive kidney transplant. In the 2011 prevalent population, 84 percent of hemodialysis patients and 81 percent of those on peritoneal dialysis had some type of primary Medicare coverage, compared to just 53 percent of those with a transplant.
Since 2005, when new fields on the revised Medical Evidence form (2728) made it possible to analyze pre-ESRD treatment, there has been little improvement in the care patients receive prior to initiation of ther-apy. Forty-two percent of new ESRD patients in 2011, for example, had not seen a nephrologist prior to beginning therapy. And among these patients, 51 percent of those on hemodialysis began therapy with a cath-eter only, compared to 19 percent of those who had received more than a year of nephrology care. Among those with a year or more of pre-ESRD

In 2011, the adjusted incident rate of ESRD averaged 449 per million popu-lation in the upper quintile and was highest in areas of the Ohio Valley, and in portions of Texas and California. • Figure 1.3; see page 430 for analytical methods. Incident ESRD patients. Adj: age/gender/race/Hispanic ethnicity; ref: 2010 ESRD patients.
With an overall rate for incident dialysis patients of 349 per million population in 2011, rates by network range from 228 in Network 16 to 427 in Network 8. The distribu-tion of patients by race continues to vary widely across the country. Blacks/African Americans, for example, constitute just 6.4 percent of the new dialysis population in Network 16, but 54 percent of patients in Network 6. • Table 1.a; see page 430 for analytical methods.

After a 1.9 percent decrease in 2010, the incident rate of ESRD (adjusted for age, gender, and race) continued to decline, falling 3.8 percent in 2011 to 357 per million population. Since 2000, changes in the adjusted rate have shown little variation, but the 2011 adjusted rate is the lowest since 1998. Ethnicity was added to the Medical Evidence form in 1995. When adjusted
for Hispanic ethnicity, rates differ little from those adjusted for age, gender, and race alone. In 2005, for example, the incident rate including ethnicity was o.5 percent greater, and in 2011 it was 0.2 percent less, at 356.4 per mil-lion population compared to 357.1. • Figure 1.2; see page 430 for analytical methods.

in the Medicare population, but has been shown to have high specificity, indicating individuals likely to have the disease. As identified from these codes within the 2010 prevalent popula-tion, CKD is recognized in 9.2 percent of older Medicare patients, and 1.4 percent of the younger employed population. When CKD patients newly identified during the year are included as well, CKD represents 11.9 percent of the Medicare population, and accounts for 27.5 percent of fee-for-service costs (see see Figure p.1 in the Volume Two Précis). When added to costs for ESRD patients, it appears that 35 percent of all Medicare expendi-tures are incurred by patients with a diagnosis of kidney disease.
Despite this high disease burden, the rate of progression to ESRD has been relatively stable over the last several years, sug-gesting that CKD patients are dying at a higher rate before they reach ESRD or that they are progressing to ESRD at a slower rate. The continuing decline in rates of death from cardiovascular disease (the major cause of mortality in the CKD population), along with improved treatment and control of hypertension and increased use of ACEIs/ARBs/renin inhibitors, suggest that progression of CKD to ESRD may indeed have slowed.
Care of CKD patients after diagnosis is challenging to assess. In the Medicare CKD population (age 65 and older), it appears that 93 percent see a primary care physician within a year of diagnosis, while 64 percent visit a cardiologist; only 31 percent, however, see a nephrologist. When restricted to patients with CKD of Stages 3–5 (based on diagnosis codes), these rates reach 93, 65, and 60 percent. Similar data are reported for the employed population. And as we show in Chapter Two, only one-third of patients with diabetes, and 5 percent of those with hypertension, receive a urine albumin test within a year, despite the fact that these measurements are recommended by the American Diabe-tes Association and the American Heart Association.
Rates of hospitalization, and of rehospitalization within 30 days, are progressively higher with advancing CKD. The issue of rehospitalization has received more attention for patients in the general population than for those with CKD, despite the fact that the rate for CKD patients is almost 40 percent higher. The rate accelerates as patients approach ESRD, reaching 43 percent in the month prior to ESRD initiation. These data show the sub-stantial burden of disease and needed care in the CKD popula-tion, burdens illustrated as well in our data on mortality and cardiovascular disease in CKD patients.
New figures show that, when compared to the general pop-ulation, Medicare Part D prescription drug use for those with CKD is dominated by diuretics, statins, beta blockers, ACEIs, and calcium channel blockers. Interestingly, thyroid replace-ment therapy is very common in the CKD population, a fact which has received little attention.
This year we again highlight data on acute kidney injury (AKI). In both the Medicare and employed populations, rates of AKI rise with age. Recurrent hospitalizations for AKI are com-mon, with rates reaching 28 percent for patients whose original AKI did not require dialysis, and 33 percent for those dialyzed during the original hospitalization; these numbers rise to 34 and 49 percent for blacks/African Americans. The rate of out-patient follow-up with a nephrologist in the year following AKI, however, is barely 20 percent.
Drug treatment changes considerably after an AKI event. The use of ACEIs/ARBs, for example, declines in the three months after discharge, but returns to the pre-AKI rate. It does not, however, exceed this initial rate, despite that fact that CKD has progressed. » Figure 1.1; see page 140 for analytical methods.

Précis: an introduction to chronic kidney disease in the united states

introductionintroduction
For many years the World Health Organization has stressed that the primary threat to public health in this century lies in four major chronic diseases: dia-
betes, cardiovascular disease, chronic lung disease, and cancer. These conditions now account for the majority of deaths not only in high-income countries but in the middle- and now the low-income nations as well.
By reducing alcohol and tobacco use, controlling salt and calorie intake, and combating a sedentary lifestyle, these diseases are largely preventable. In Sep-tember, 2011, the United Nations held a summit on chronic diseases, looking at how member states can address their impact, and discussing the widespread problems of premature loss of life, loss of economic productivity, and financial stress on families, which can contribute to advancing poverty. For the first time, because of its impact on morbidity and mortality and its substantial cost to the healthcare system, chronic kidney disease was added to the list of major diseases.
All countries now recognize the substantial impact of an increasing popula-tion with kidney failure, people who face premature death if they do not receive dialysis or a kidney transplant. The reality is that many countries struggle with the costs of providing end-stage renal disease (ESRD) care, costs which place min-istries of finance at odds with ministries of health. The demand for transplant organs has led to the emergence of transplant tourism, with the buying and selling of organs. Some have expressed that a regulated market system would help fill this demand. Others suggest that prevention is a more sustainable approach, for with-out it the need will continue to grow, outpacing the pool of potential donors and increasing the known risks of the exploitation of poor populations at the expense of the wealthy. While the Istanbul Declaration on organ trafficking and transplant tourism has denounced the practice, the large number of patients across the globe who have advancing kidney disease continues to fuel demand.
The growing number of ESRD patients thus needs to be addressed in terms not only of its public health disease burden, but of its costs to the healthcare system, and of the high demand for replacement organs. And the overall prevention of kidney disease needs to be viewed in context of competing demands for resources, particularly in the difficult economic times currently faced around the world.
As shown in the Venn diagrams on the next page, 9.3 and 8.5 percent of patients in the general population had diabetes and cardiovascular disease, respectively, in 2010, while 13.1 percent had CKD, defined by an estimated GFR less than 60 ml/min/1.73 m2 or a urine albumin-to-creatinine ratio (ACR) of 30 mg/g or higher. Using only the eGFR, CKD prevalence was 6.3 percent; using only the ACR, it reached 9.2 percent — on a par with diabetes and cardiovascular disease. There is now substantial evidence that both eGFR and urine ACR are predictors of all-cause death, cardiovascular events, and ESRD (Lancet 2010).
With diabetes and hypertension known to be major risk factors for CKD, the awareness, treatment, and control of these conditions are crucial. NHANES data show that blood pressure control in the general population improved between 1988–1995 and 2005–2010, reaching almost 50 percent. LDL cholesterol control increased from 25 to 33 percent, while glycemic control rose from 31 to 48 percent overall, and from 37 to 58 percent in patients whose CKD is defined by an eGFR less than 60. These improvements in treatment and control may be contributing to the flat ESRD rate, despite the greater burden of diabetes in the general population.
While CKD has been characterized from population-level estimates in the NHANES data, much of the disease is silent and unrecognized, complicating any full assessment of its impact. We present data on CKD recognized through diag-nosis codes reported on claims — an approach which clearly underestimates CKD

CKD in the general population
Between 1988–1994 and 2005–2010, the overall prevalence estimate for CKD — defined by an eGFR <60 ml/ min/1.73 m2 or an ACR ≥30 mg/g — rose from 12.3 to 14.0 percent. The larg-est relative increase, from 25.4 to 40.8 percent, was seen in those with cardiovascular disease. For eGFR <60, prevalence rose from 4.9 to 6.7 percent, with the largest increase in those age 40–59; for ACR ≥30 mg/g, the estimate rose from 8.8 to 9.4. » Table 1.a; see page 140 for analytical methods.

1.11 Distribution of markers of CKD in NHANES participants with diabetes,

of NHANES 2005–2010 participants, showing the percentage in each popu-lation with an eGFR <60 m/min/1.73 m2 and an ACR ≥30 mg/g. Nearly 28 percent of participants with cardiovascular dis-ease (CVD) had an eGFR less than 60, compared to 19.3, 12.9, and 7.4 percent of those with diabetes, hypertension, and a high body mass index, respec-tively. Participants with diabetes were the most likely to have an ACR ≥30 mg/g, at 29.9 percent, compared to 24.3, 14.8, and 11.7 percent among those with CVD, hypertension, and a high BMI.
Nearly 11 percent of participants with CVD had both an eGFR <60 and an ACR ≥30, compared to 8.6 percent of those with diabetes and 4.1 and 2.1 percent, respectively, of those with hypertension and a high BMI. » Figure 1.11; see page 140 for analytical methods.

formed that year. Living donor donation rates appear to be
rebounding, while donations from deceased donors have
been stable. Risk factor monitoring among transplant
patients has improved, yet rates of influenza vaccinations
are still relatively low.
Highlighted data on pediatric ESRD patients show
that the number with cystic kidney disease has increased,
while there are fewer patients with glomerular disease.
Rates of hospitalization for pneumonia are greatest over-
all in patients younger than 10, and, in the hemodialy-
sis population, mortality is greatest in the first months
of therapy.
Dialysis providers continue to consolidate, with Frese-
nius Medical Care announcing the purchase of additional
units in July, 2011; the company thus maintains its position
as the largest provider of dialysis care in the United States.
Dialysis Clinic, Inc. continues to have the lowest standard-
ized hospitalization and mortality ratios among the large
providers, while, among the smaller providers, hospital-
based units have the highest standardized mortality ratios.
We conclude the Précis with data on the costs of ESRD
patient care, which rose very little in 2009. Costs per per-
son per year remain highest for hemodialysis patients, at
$82,285, compared to $61,588 and $29,983 for peritoneal
dialysis and transplant patients.» Figure p.1; see page 378 for analytical methods. Period prevalent

In 2009, 116,395 new dialysis and transplant patients initiated ESRD therapy, for an adjusted rate per million population of 355. More than 571,000 patients were receiving treatment on December 31, 2009, for an adjusted rate of 1,738 per million population. Nearly 399,000 of these patients were being treated with dialysis, while 172,553 had a functioning graft; 90,118 ESRD patients died during the year. A total of 17,736 transplants were performed during 2009, including 6,388 from living donors. More than 34,000 patients were added to the transplant wait list, 85,539 were on the kidney-alone and kidney/pancreas wait lists at the end of 2009, and the median time on the list (for pediatric and adult patients combined) was 1.7 years.
With Medicare spending for ESRD at $29 billion, and non-Medicare spending at $13.5 billion, total ESRD costs in 2009 reached $42.5 billion. Medicare costs per per-son per year were more than $70,000 overall, ranging from $29,983 for transplant patients to $82,285 for those receiving hemodialysis therapy. » Table p.a; see page 378 for analytical methods. Dialysis & transplant patients, 2009.
The size of the prevalent dialysis popula-tion increased 4 percent in 2009, reaching 398,861, and is now 40 percent larger than in 2000. The size of the transplant popu-lation rose 4.2 percent, to reach 172,553 patients, while the number of incident patients rose 3.3 percent, to 116,395. These data suggest longer lifespans for preva-lent patients, ultimately influencing the steady growth of this population and the annual expenditures these patients incur. » Figure p.3. Incident & December 31 point prevalent ESRD patients.
The number of new dialysis patients rose 3.5 percent in 2009 — up from a 1.2 percent growth in 2008 — to 112,782. Just over 5,600 patients with graft fail-ure returned to dialysis from transplant, a one-year increase of 2.7 percent. The number of patients restarting dialysis increased 6.6 percent, to 3,492. Overall, the CMS Annual Facility Survey showed 121,880 patients starting or restarting dialysis in 2009, up 3.6 percent from 2008. » Figure p.2; see page 378 for analytical meth-ods.

Pr
INTRODUCTION
Peritoneal dialysis now accounts for 6–7 percent of the inci-
dent and prevalent dialysis populations, a level far lower
than the 12–18 percent in the 1980s and 1990s; there are
signs, however, that use of this therapy is growing. The
number of kidney transplants reached 17,736 in 2009, while
the prevalent transplant population increased 4.2 percent,
to 172,553, despite continued growth in the number of
patients on the transplant wait list. The median time on the
kidney-only and kidney-pancreas wait lists was 1.7 years.
In the rest of this Précis we highlight data from Volume
Two. We show, for instance, that rates of new ESRD cases
remain quite stable, at 355 per million population in 2009.
While ESRD due to diabetes has also been stable over the
last decade, at a rate of 154, ESRD caused by hypertension
has grown 10 percent. The prevalence of ESRD continues to
grow at a rate of 2 percent per year, reaching 1,738 in 2009.
Patients who see a nephrologist for more than 12
months before starting dialysis are the most likely to use
a fistula or internal graft at the first outpatient dialysis
treatment. Since nephrologists are central to discussions
with patients and families about ESRD treatment options,
greater pre-ESRD referral would help ensure increased use
of fistulas, which are associated with the lowest rates of
adverse events.
The treatment of anemia has changed during the last
four years, after changes in product labeling from the
FDA and in payment structures from CMS. Hemoglobin
levels at the initiation of dialysis have fallen below 10 g/dl,
a level not seen since December, 2000, while the percent-
age of patients using an erythropoiesis stimulating agent
(ESA) prior to initiation has also fallen — to 22 percent, a
level not seen since April, 1996. Hemoglobin levels at
six months following the start of ESRD therapy are now
lower than in 2001, yet the ESA dose is substantially higher.
Hemoglobin levels in the prevalent dialysis population
have decreased as well.
Hospitalizations continue to be an area of concern,
with admissions for infection in hemodialysis patients
43 percent higher than in 1993. New data on rehospitaliza-
tions show that rates are twice as high for ESRD patients
as in the general Medicare population. Mortality rates
continue to improve, though more slowly for the first year
of treatment than for the years following. Rates for ESRD
patients, however, are 2.0–2.5 times greater than for gen-
eral Medicare patients with cancer, diabetes, congestive
heart failure, or CVA/TIA.
This year we present new data on the Medicare Part D
prescription drug benefit, which started in 2006. ESRD and
non-ESRD CKD patients have higher Part D coverage with
the low income subsidy than do general Medicare patients
and, not surprisingly, out-of-pocket expenditures are
greatest for ESRD patients, at nearly $6,000 per year com-
pared to $1,985 in the general Medicare population and
$3,550 for those with a diagnosis of CKD.
The kidney transplant wait list continues to grow,
reaching 80,848 in 2009; 17,736 transplants were per-
The size of the ESRD population reached a new high in 2009, with 571,414 patients under treatment. The number
of patients returning from a failed transplant rose to 5,606, while the number restarting dialysis increased to 3,492.

paii Summary statistics on reported ESRD therapy in the United States, by age, race, ethnicity, gender, & primary diagnosis, 2009
A Incident counts: include all known ESRD patients, regardless of any incomplete data on patient characteristics and of U.S. residency status.
B Includes only residents of the 50 states and Washington D.C. Rates are adjusted for age, race, and/or gender using the estimated July 1, 2005 U.S. resident population as the standard population. All rates are per million population. Rates by age are adjusted for race and gender. Rates by gender are adjusted for race and age. Rates by race are adjusted for age and gender. Rates by disease group and total adjusted rates are adjusted for age, gender, and race. Adjusted rates do not include patients with other or unknown race.
C Patients are classified as receiving dialysis or having a functioning transplant. Those whose treatment modality on December 31 is unknown are assumed to be receiving dialysis. Includes all Medicare and non-Medicare ESRD patients, and patients in the U.S. Territories and foreign countries.
D Deaths are not counted for patients whose age is unknown.
E Age is computed at the start of therapy for incidence, on December 31 for point prevalence, at the time of transplant for transplants, and on the date of death for death.
F Includes patients whose modality is unknown.
G Unadjusted total rates include all ESRD patients in the 50 states and Washington D.C.
H Total transplants as known to the USRDS; 57 transplants with unknown donor type excluded from counts.
I Adjustments using the Bureau of Labor Statistics inflationary adjustment and the CMS inflation adjustment for the medical component.

This year we include data on rates of hospitalization for vascular access infections, looking at differences by provider and region. Rates are more than three times higher in patients using a cath-eter at dialysis initiation rather than an internal access, are slightly lower in SDOs and hospital-based units, and are also lower in the western region of the country. These findings may reflect differences in infection prevention protocols, and should be assessed.
Hospitalizations for heart failure and/or fluid overload differ in the SDOs and other providers, particularly as related to the rate of extra dialysis procedures performed in patients with heart fail-ure. Within the large dialysis organizations, for example, Fresenius has higher rates of billed extra dialysis runs compared to DaVita and DCI. These variations need to be investigated to determine which practice patterns relate to lower rates of infectious complications.
As in past ADRs, we conclude the chapter with comparisons of mortality and hospitalization ratios by provider and geographic region; we also present outcomes across large and small dialy-sis organizations and hospital-based units. Hospitalization ratios are very similar across the large groups, though lower in DCI units. Ratios for SDOs are lowest in the Pacific region. And for hospital-based units, both mortality and hospitalization ratios are greatest in the East South Central, South Atlantic, and West South Central regions. These differences have narrowed compared to prior years, an important change. We will continue to assess these relative outcomes between providers, and examine them over time to determine areas for improvement.

treatment with iv iron Figures 10.6–8 illustrate IV iron use in the dialysis population. In 2008, one in four prevalent patients used Ferrlecit, while 61 percent were treated with Venofer; only 0.3 percent of dialysis patients received INFeD. These numbers vary considerably, however, by unit affiliation. In independent units and those owned by Fresenius, 37–42 percent of patients were treated with Ferrlecit; in DaVita and DCI units, in contrast, Ferrlecit was used by only 2–4 percent of the dialysis population, while 87 percent received Venofer.
In the first six months of dialysis, the number of months in which patients receive IV iron now ranges from 4.4 in Fresenius and hospital-based units to 4.8 in those owned by DCI. The mean total IV iron dose in this period increased 13.2 percent between 2003 and 2008 — from 1,973 units to 2,233 — and now ranges from 1,945 in hospital-based units to 2,274 in those owned by small dialysis organizations (SDOs). ∏ Fig-ures 10.6–8; see page 483 for analytical methods.

In 2008, 15.5 percent of prevalent dialysis patients re-ceived one or more tranfusions, only slightly higher than the 15.3 percent reported for 2003. By unit affili-ation, the percentage ranges from 13.8 in DaVita and DCI units to 17.1–17.6 in hospital-based and indepen-dent units. ∏ Figure 10.9; see page 483 for analytical meth-ods.

In 2008, two in three prevalent, EPO-treated dialysis patients had a hemoglo-bin of 10–<12 g/dl, considerably higher than the 51 percent in 2007 (reported in the 2009 ADR), and perhaps a sign that providers are responding to studies showing the risks of higher hemoglobin levels. The percentage of patients with a level of 13 g/dl or above now ranges from 1.1 in DCI units to 3.3 in those that are hospital-based. ∏ Figure 10.5; see page 483 for analytical methods.

esrd providers10introduction
DCI; these organizations manage 3,330 units across the U.S. Smaller dialysis organizations (SDOs) treated 33,084 patients in 438 units, in-dependently owned units accounted for 63,952 patients in 927 units, and the remaining pa-tients were treated in hospital-based units.
Recent clinical trials have shown adverse outcomes when hemoglo-bin levels are targeted to 13 g/dl and above. The highest percentage of pa-tients with a hemoglobin of 10–<12 earlier occurred in units owned by Di-alysis Clinic, Inc. (DCI), but is now reported in units owned by Fresenius. Use of intravenous iron products to treat anemia varies across providers, with DaVita and DCI almost exclusively using Venofer, and Ferrlecit and Venofer used equally in Fresenius units. And the total months of IV iron therapy in the first six months of ESRD has now increased to 4.5, with the mean IV iron dose now at 2,233 mg; this dose is highest in DaVita units, at 2,332 mg, and lowest in hospital-based units, at 1,945 mg.
It is important that patients have adequate iron stores in order to maintain optimal hemoglobin levels. The percentage of patients receiving ferritin testing for three consecutive months after starting ESA therapy, however, is only 8.0 in DCI units, lower than that reported for other pro-viders. The new dialysis bundled payment system, taking effect in 2011, will incorporate all extra monthly tests into a single monthly payment, and its effect on the marked differences in testing rates across providers will be monitored closely by the USRDS in future ADRs.
This year we again assess preventive care services delivered by pro-viders. Glycemic control testing in diabetic patients, for example, differs across providers, with 63–64 percent of patients in Fresenius and DaVita units, and in the SDOs, receiving at least four glycosylated hemoglobin tests in a year, compared to 44–48 percent in DCI and hospital-based units. Rates of vaccinations, both for influenza and for pneumococcal pneumo-nia, have improved during the past several years.
Variations in Medicare payments across provider groups are con-siderable, particularly in the areas of erythropoiesis stimulating agents (ESAs), IV iron, and IV vitamin D. Laboratory costs, however, are fairly consistent, with the exception of DCI, for which costs are lower by nearly one-third compared to other providers. As these payments become fixed under the new payment bundle, it will be important to monitor the use of services to determine any changes in clinical performance.
The network of dialysis providers has
stabilized since the consolidation of
Gambro units into DaVita and RCG units
into Fresenius. At the end of 2008, 117,000
prevalent patients were being treated by
Fresenius, 104,000 by DaVita, and 13,000 by

102ii Percent change in the number of dialysis units & patients, 2003 to 2008, by ESRD network
103ii Dialysis unit & patient counts, by unit affiliation
104ii Dialysis unit distribution, by affiliation & time managed (time under chain ownership)
Between 2003 and 2008, the number of dialysis units grew 36–37 percent in Networks 9 and 14, and 28–29 percent in Networks 10, 15, and 16. In Networks 2 and 5, in contrast, the number of units rose less than 10 percent. The number of patients rose at least 25 percent in Networks 14, 15, 16, and 18. ∏ Figure 10.2; see page 483 for analytical methods. CMS Annual Facility Survey.
Dialysis unit and patient counts rose nearly 20 percent between 2003 and 2008. DaVita showed the largest growth — 163.9 percent in units and 138.3 percent in patients — in large part due to the purchase of Gambro in October, 2005. Hospital-based and in-dependent units experienced negative growth in both the number of units and the number of treated patients during the time period. ∏ Figure 10.3; see page 483 for analytical methods. CMS Annual Fa-cility Survey.
The percentage of units remaining under consistent owner-ship for five or more years fell from 70.6 in 2003 to 55.8 in 2008, a reflection of major unit purchases by DaVita and Fresenius in 2005 and 2006. It appears, however, that pur-chases of independent and hospital-based units by the large chains may be slowing. In 2003, for example, 57.9 percent of independent units were under the same ownership for five or more years, compared to 62.4 percent in 2008; in hospital-based units, 87.5 percent were owned for five or more years in 2003 compared to 90.9 percent in 2008. ∏ Figure 10.4; see page 483 for analytical methods.

two or more years, and adjusted first-year rates for hemodialysis patients now show three years of successive declines. The use of catheters is still an important issue here, as more than 80 percent of patients have a catheter at their first outpatient dialysis, and early morbidity from vascular access infections in the first months of dialysis is a concern (see Chapter One for data on infectious hospitalization rates in the first months of hemodialysis). ¶ Greater growth in general Medicare costs compared to those for eSrd — in 2006, 16.9 versus 4.9 percent — along with the inclusion, starting in 2006, of Part D in the total Medicare costs, have led to a decline in the percentage of the Medicare budget spent on eSrd, now at 5.8 percent. In absolute dollars, however, the program grew 6.1 percent in 2007. ¶ Costs for both diabetic and non-diabetic Medicare patients with eSrd continue to rise. The same is true for patients with employer group health plan (eGHP) coverage, though costs here are significantly higher. The average Medicare eSrd patient with diabetes now costs $72,461 per year, compared to $98,721 in the eGHP population.

p3ii Patient counts, by modality
In 2007, 111,000 new dialysis and transplant patients initiated eSrd ther-apy, for an adjusted rate per million population of 354 — a 2.1 percent decrease from the rate of 362 in 2006 (Figure p.4). More than 527,000
patients were receiving treatment on December 31, 2007, for an adjusted rate of 1,665 per million population — 2.0 percent higher than the 2006 rate of 1,632. Nearly 369,000 of these patients were being treated with dialysis, while 158,739 had a functioning transplant. A total of 17,513 transplants were performed dur-ing the year — 6,041 from living donors — and 87,812 eSrd patients died. Nearly 33,000 patients were added to the transplant wait list in 2007, and 73,555 were on the list at the end of the year; the median time on the list was 1.5 years.
With Medicare spending for eSrd at $23.9 billion, and non-Medicare spending at $11.4 billion, total eSrd costs in 2007 reached $35.3 billion. Medicare costs per person per year were nearly $62,000 overall, ranging from $24,572 for transplant patients to $73,008 for those receiving hemodialysis. ¶ Table p.a; see page 362 for analytical methods. Dialysis & transplant patients, 2007.
The number of new dialysis patients rose just 0.85 percent in 2007 — down from 3.6
percent in 2006 — to 107,644. Nearly 5,400 patients with graft failure re-turned to dialysis from transplant, a one-year decrease of 3.2 percent. The number of patients restarting dialysis, in contrast, grew 12.3 percent, to 3,031. Overall, the cMS Annual Facility Sur-vey showed 116,073 patients starting or restarting dialysis in 2007, up 0.9 percent from 2006. ¶ Figure p.2. CMS Annual Facility Survey.
The prevalent dialysis population grew 30 percent between 2000 and 2007, reaching nearly 370,000. The
transplant population increased 46 percent in this same period, and in 2007, with almost 159,000 patients, showed a one-year growth of 4.9 percent. The number of incident patients, in contrast, remained stable in 2007, at 111,000. These data suggest that the prevalent popu-lation is living longer, influencing both the growth of the treated eSrd population and the annual expenditures these patients incur. ¶ Figure p.3.

In 2005 the World Health Organization reported on the impact of chronic diseases in low, middle, and high income countries. The presentation focused on premature loss of life and on the economic impact of deaths during individuals’ most productive years. With the impact of chronic diseases in the United States long an area of concern, we summarize one perspective in the Venn diagrams on the next page, looking at diabetes, cardiovascular
disease (cVd), chronic kidney disease (cKd), and end-stage renal disease (eSrd). ¶ The growth of diabetes in the Medicare population — from 16.1 percent in 1997 to 24.6 percent in 2007 — is associated with a 32 percent increase in the proportion of Medicare costs consumed by patients with the disease. Cardiovascular disease, including hypertension, has long been an issue within the Medicare population. But while growth in the treated eSrd population has also long been reported, cKd has received little attention, despite the increased frequency of its diagnosis and the doubling of its associated costs. Taken together, expenditures for the care of patients who have cKd or eSrd now total 32 percent of the Medicare budget — up from 18.5 percent just ten years ago. The expanding size of the eSrd program, and projections that it will double in the next ten years (see Figure 2.1) suggest that the population at risk for kidney disease should be addressed with detection and prevention strategies to reduce the long-term burden of eSrd. ¶ The size of the eSrd population hit a new high in 2007, with 527,283 patients under treatment, while the number of new cases — precisely 111,000 — was almost exactly the same as in 2006. The number of patients starting dialysis, or returning to dialysis after a failed kidney transplant or the recovery of kidney function, reached 116,073, a 0.9 percent increase. Interestingly, the number returning from a failed transplant dropped to 5,398 from 5,578 in 2006. The number restarting dialysis, however, grew 12.3 percent, to a new high of 3,031. ¶ Peritoneal dialysis now accounts for 5–6 percent of the incident and prevalent dialysis populations, continuing to fall from peaks of 13 and 11 percent in the 1990s. The number of kidney transplants reached 17,513 in 2007, while the prevalent transplant population rose 3.6 percent, to 158,739, despite continued growth in the number of patients on the transplant wait list. The median time on the wait list was 678 days. ¶ In 2006, 41 percent of prevalent dialysis patients had a functioning fistula (see Figure hp.11), exceeding the 1997 KdoQi target of 40 percent, and leading to a new target of 66 percent. Fistula placement rates, however, appeared to peak in 2006, and in 2007 fell for the first time. The steep fall in graft placement rates appears to be slowing, while catheter placement rates continue to fall, reaching a level below that of 1991 and perhaps contributing to the recent decline in rates of hospitalization for vascular access infection (see Figure 6.4). ¶ Many patients receive no nephrologist care, dietary care, or treatment with erythropoietin stimulating agents (eSas) prior to beginning eSrd therapy. These findings sug-gest that planning for the transition to eSrd is poor, and that the Medicare cKd education benefit, included in the 2008 Medicare Improvements for Patients and Providers Act (MiPPa), needs to address the selection of patient modality and dialysis access, preemptive kidney transplantation, and cardiovascular risk factors. ¶ As of March, 2007, mean monthly hemoglobin levels have fallen below 12 g/dl. Seven percent of prevalent dialysis patients now have a mean monthly level less than 10 g/dl, and the percentage with a mean level above 13 g/dl has fallen slightly, to 16.7 percent. These changes may reflect concerns over high levels reported in clinical trials (cHoir and creaTe) in 2006, changes mandated by the Fda and cMS to eSa package inserts, and changes in eSa pay-ments by cMS when hemoglobin levels exceed 13 g/dl for three months. ¶ After rising steadily over several years, rates of hospitalization for infection again fell in 2007 — an important change in patient morbidity. Incident-based mortality rates continue to fall for those on eSrd treatment

had an AV access either in use or maturing at the first out-patient dialysis treatment, up only slightly from 35.5 percent in 2007. In July, 2010, CMS began requiring the reporting of monthly data on vascular access use; as these data become available, the USRDS will examine prevalent access use and transitions in vascular access during the first months of dialysis.
The lack of progress in the use of catheters is a major concern, and may relate to the persistently high rates of hospitalization for infection (noted in Chapter Three). The CDC restarted its infection control survey in 2012 and 2013, collecting data on unit practices related to access prepa-ration for cannulation, on reuse practices, and on use of catheter antibiotic lock solutions. These practices will be assessed in the future to help guide targets for infection control and to reduce related complications. ◆ Figure 2.1; see page 431 for analytical methods.

2.9 Mean monthly hemoglobin & mean EPO dose per week: peritoneal dialysis patients
When compared to 2007 patients, those starting peritoneal dialysis in 2011 did so with lower hemoglobins one month post-initiation, at 10.9 and 10.2 g/dl, respectively. In 2011, mean hemoglobin levels at six months following initiation were 10.9 g/dl. The mean EPO dose per week was 10,482 units, compared to 10,542 in 2007.
In 2011, the proportion of peritoneal dialysis patients receiving IV iron in each of the first six months of dialysis was 11.6 percent, in contrast to 32 percent among hemodialysis patients.
The percentage of peritoneal patients receiving a transfusion has increased little since 2010, and in June of 2011 was slightly higher in whites compared to blacks/African Americans, at 3.1 and 3.0, respectively. ◆ Figures 2.10–13; see page 432 for analyt-ical methods. Incident peritoneal dialysis patients; for Figure 2.13, each month includes patients with a claim for peritoneal dialysis.
At the end of 2011, 66 percent of prevalent peritoneal dialysis patients had a mean monthly hemoglobin less than 11 g/dl, while 26 percent had hemoglobins that ranged from 11 g/dl to less than 12 g/dl . The mean EPO dose per week fell each month within the year, ending at 10,104 units in the month of December, while the mean hemoglobin at that time was 10.5 g/dl. ◆ Figures 2.8–9; see page 432 for analytical methods.

OVER THE PAST DECADE, improvements in ESRD care have been addressed by several organizations. Most notable is CMS’s assessment of provider performance through its Dialysis Facility Compare project (www.medicare.gov/dialysisfacilitycompare), which reports provider measures based on quality improvement targets and KDOQI published guidelines. The project is currently undergoing transition to a full web-based data entry sys-tem, which will include monthly laboratory data from providers. There have been challenges in implementing the system, but by the summer of 2013 most providers should be entering data. Until that time, some elements traditionally reported under the Clinical Performance Measures (CPM) program will not be up-to-date.
In Figure 2.1 we present data on KDOQI targets for dial-ysis therapy, vascular access, and clinical indicators, and look at other targets based on practice guidelines and safety issues. Dialysis adequacy has inched up slightly, with 95 percent of hemodialysis patients achieving a URR of ≥65 percent — a new high — and 87 percent of perito-neal dialysis patients achieving a Kt/V of ≥1.7. Forty-six and 51 percent, respectively, of diabetic ESRD patients received recommended glycemic control testing and lipid testing in 2011, while 65 percent of ESRD patients received an influenza vaccination.
Views of anemia treatment continue to evolve, as safety concerns about targeting hemoglobin levels above 11 g/dl have emerged from clinical trials. The new FDA label for ESAs, released in June, 2011, states “In controlled tri-als, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when admin-istered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.” The label also states that “No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks.” The FDA recommends that clinicians “Use the lowest dose that will maintain a hemoglobin level suffi-cient to reduce the need for RBC transfusions.” Based on new recommendations, these changes should reduce the risk of adverse cardiovascular events and strokes.
The new FDA recommendations and the concerns arising from clinical trials appear to be guiding clinical
practice. At six months after initiation in 2011, the mean hemoglobin level in patients is now lower than its peak seen in 1999. And the mean ESA dose used to achieve these levels is below that of 1999.
Data on iron dosing practices show that, in the first six months of dialysis treatment, more than 50 percent of patients receive monthly IV iron, a new high. Another 20 percent receive IV iron in five of the first six months of dialysis therapy.
Trends in the monthly percentage of patients receiving a transfusion have changed since 2010. Among hemodial-ysis patients, the transfusion rate, at 2.7–2.9 percent at the beginning of 2010, reached 3.3–3.8 percent in the first six months of 2012. Among peritoneal dialysis patients, the rate has increased from 2.3–2.9 to 3.0–3.9. Further anal-ysis will be needed into how these changes might affect dialysis patients on the waiting list for transplantation.
Comprehensive patient care has long been a focus of the ADR. Among diabetic patients, there has been a slight decline in the percentage of patients receiving recom-mended glycemic control testing and lipid testing, so that the overall rate of comprehensive diabetic monitoring has fallen from 17 percent in 2008–2009 to 14.4 percent in 2010–2011. It is not clear whether the new bundled pay-ment system has had an impact on this aspect of patient care, or whether this decrease will have a collateral effect on diabetes-specific hospitalizations.
Influenza vaccination rates have risen from 46 percent in 2001 to 65 percent in 2011 — still below the HP2020 target of 90 percent. The percentage of patients vacci-nated against pneumococcal pneumonia, peaking at 25.8 percent in 2008–2009 (reported in the 2012 ADR), has not improved, remaining at 25.6 percent in 2010–2011.
Vascular access has received increased attention since the release of data showing high catheter use at initiation and increasing rates of hospitalization due to infection in the first months of therapy. Unfortunately, the use of catheters at the start of ESRD remains high and relatively unchanged, at 81 percent. The CMS Fistula First program has worked to increase the use of arteriovenous (AV) fis-tulas, and to transition patients off dialysis catheters. Just 37 percent of 2011 incident hemodialysis patients, however,

2.3 Mean monthly hemoglobin & mean EPO dose per week: hemodialysis patients
When compared to 2007, incident hemodialysis patients starting dialysis in 2011 did so with lower hemoglobins one month post-initiation, at 10.7 and 10.1 g/dl, respectively. In 2011, the mean hemoglobin level six months after initiation was slightly below 10.9 g/dl.
The mean EPO dose per week at six months after initiation was 15,213 units in 2011, compared to 20,506 units in 2007.
Between 2010 and 2011, the proportion of incident hemodi-alysis patients receiving IV iron in each of the first six months of dialysis showed a relative increase of 12 percentage points, to 52.1 percent.
The percentage of hemodialyis patients receiving a trans-fusion has increased little since 2010, and in June of 2011 was slightly higher in whites compared to blacks/African Americans, at 3.5 and 3.1 percent, respectively. ◆ Figures 2.4–7; see page 432 for analytical methods. Incident hemodialysis patients; for Figure 2.7, each month includes patients with a claim for hemodialysis.
At the end of 2011, 58 percent of prevalent hemodialysis patients had a mean monthly hemoglobin less than 11 g/dl, while 31 percent had hemoglobins that ranged from 11 g/dl to less than 12 g/dl. The mean EPO dose per week fell each month within the year, ending at 12,460 in the month of December, more than 3,600 units less than the average dose at the end of 2010; the mean hemoglobin at the end of 2011 was 10.7 g/dl. ◆ Figures 2.2–3; see page 431 for analytical methods.

4.b Cardiovascular disease & pharmacological interventions (row percent), by CKD status, 2011
Although prior publications have dem-onstrated a strong inverse relationship between the likelihood of cardioprotec-tive therapy use and advanced CKD stage, our overview of 2011 prevalent Medicare patients with Part D coverage provides some reassurance that this practice pat-tern has changed. While ACeI/ArB use in CHF patients does decline with advancing CKD, the same is not true of beta blocker therapy, which increases with CKD stage. The use of beta blocker therapy after AMI also demonstrates a change with respect to CKD. Despite earlier data indi-cating underutilization inversely related to eGFr, 76 percent of 2011 CKD patients with AMI — and a surprising 82 percent of those with Stage 4–5 CKD — received a beta blocker.
The treatment of AFIB presents a special clinical problem in CKD patients. In com-parisons of warfarin to newer oral antico-agulants in CKD patients, dabigatran was associated with the largest reduction in risk of ischemic stroke and apixaban with the greatest reduction in risk of serous hemorrhage (Hart et al, 2012). None of these trials, however, enrolled patients with estimated creatinine clearances of <25 ml/min. Despite the absence of clinical trial data, approval in the U.S. was given to newer oral anticoagulants — dabigatran, rivaroxaban, and apixaban — for preven-tion of ischemic stroke in non-valvular AFIB in patients with estimated creatinine clearances as low as 15. All three agents are approved for use in patients with CKD of Stage 3 or Stage 4, but not for those with Stage 5 CKD. In 2011, 2.4 percent of AFIB and with CKD of Stages 4–5 received dabi-gatran. Close attention will need to be paid to the expected increase in serious hemor-rhagic events associated with these agents in patients with advanced CKD, but avail-able data imply that newer oral anticoagu-lants are superior to warfarin in efficacy and safety. • Table 4.b.

Incidence, prevalence, patient characteristics, & modality
Here and there awareness is growing that man, far from being the overlord of all creation, is himself part of nature, subject to the same cosmic forces that control all other life. Man's future welfare and probably even his survival depend upon his learning to live in harmony, rather than in combat, with these forces.
Rachel Carson,"Essay on the Biological Sciences"
CHAPTER ONEINCIDENCE, PREVALENCE, PATIENT CHARACTERISTICS, & MODALITY
113 | 119
In 2010, the number of new patients starting therapy on hemodialysis declined for the first time in more than three decades. The population initiating on peritoneal dialysis, in contrast, grew for the second year in a row, and now accounts for 6.6 percent of patients with a known dialysis modality. This change may foreshadow those to come
under the new bundled payment system, with its clear incentives for this form of home dialysis. Total incident dialysis cases rose 0.27 percent in 2010, to 114,083, while 2,863 patients received a preemptive transplant as their first ESRD modality; a total of 116,946 patients began ESRD therapy in 2010.
The rate of new ESRD cases per million population, which has been relatively stable since 2000, fell 2.0 percent in 2010, to 348. Growth continues to be driven by a relatively linear increase in the number of patients age 45–64; growth in the population age 65 and older, in contrast, has slowed considerably, but a slight upturn is present among those age 65–74, which could reflect the emergence of the post-World War II baby boomers into retirement age.
The incidence of ESRD in the black/African American population has finally started to decline, overall and for ESRD due to diabetes. Among those age 20–39, however, differences between whites and blacks/African Americans continue to be dramatic, with rates among the latter up to 3.8 times greater. Rates are also considerably higher for blacks/African Americans age 60 and older than for their white counterparts, though the gap is beginning to narrow.
The December 31, 2010 prevalent population included 383992 patients on hemodialysis and 29,733 on peritoneal dialysis, as well as 179,361 with a functioning kidney transplant; the total treated ESRD population thus rose to 593,086 — growth of 4 percent from 2009, which is the smallest increase in 30 years. The rate of prevalent ESRD cases reached 1,752 per million population, an increase of 1.1 percent from 2009, and also the slowest growth in the last three decades.
Insurance coverage in the dialysis population continues to change, with more incident dialysis patients now covered by Medicare Advantage. Private insurance, in contrast, is dominant among patients who receive a preemptive kidney transplant. In the 2010 prevalent population, 84 percent of hemodialysis patients and 79 percent of those on peritoneal dialysis had some type of Medicare coverage, com-pared to just 65 percent of those with a transplant.
Nephrology care prior to ESRD continues to be a concern. Since the 2005 introduction of the new Medical Evidence form (2728), with fields addressing pre-ESRD care, there has been little progress made in this area (pre-ESRD data, however, should be interpreted with cau-tion because of the potential for misreporting). Forty-three percent of new ESRD patients in 2010, for example, had not seen a nephrologist prior to beginning therapy. And among these patients, 88 percent of those on hemodialysis began therapy with a catheter, compared to 54 percent of those who had received a year or more of nephrology care. Among those with a year or more of pre-ESRD nephrologist care, in contrast, 26 percent began therapy with a fistula — eight times higher than the rate among non-referred patients.
Data on patient care at the start of ESRD therapy show that the percentage of patients receiving an erythropoiesis stimulating agent (ESA) prior to initiation continues to decline, reaching just 20 percent in 2010 compared to one-third in the early part of the decade. This may reflect concern over potential adverse events when hemoglobin levels are targeted to a level above 12 g/dl. The mean hemoglobin at initiation of ESRD treatment is now 9.73 g/dl. These changes place different demands on care after the initiation of dialysis, and may alter the likelihood of a patient receiving a blood transfusion. The balance between cardiovascular risk with a hemoglobin greater than 12 g/dl and the risk of transfusion with lower hemoglobin levels needs to be addressed by patients and their physicians, particularly in the case of patients contemplating a kidney transplant, for whom sensitization from blood transfusions is to be avoided if at all possible.
The percentage of dialysis patients beginning therapy with an estimated glomerular filtration rate (eGFR, calculated with the CKD-EPI formula) above 15 ml/min/1.73 m2 continues to rise. It is not clear if this progressive increase is the result of severe comorbidity or a simple numerical starting point based on the ability to calculate the eGFR. Hopefully, symptoms and complications of uremia are still the primary indications for starting renal replacement therapy rather than a simple number, one which has been brought into question in recent years in controlled trials of early versus later dialysis initiation.
Biochemical data, collected on the Medical Evidence form since 2005, show that 57 percent of new patients in 2010 had an albumin less than the lower limit of normal, and 55 percent had a hemoglobin lower than 10 g/dl. Total cholesterol was greater than 200 mg/dl in 16 percent of patients, while 28 percent had an LDL level greater than 100 mg/dl, and 58 percent had an HDL level less than 40 mg/dl. Among patients with diabetes, 28 percent had a hemoglobin A1c level greater than 7 percent.
Recent changes and new incentives in the bundled prospective payment system for dialysis patients, introduced in January, 2011, may alter several characteristics of the incident and prevalent populations — particularly, due to cost incentives, the mix of peritoneal dialysis and hemodialysis patients. It is unclear how the expansion of peritoneal dialysis will affect patient outcomes, and how the new incentives will impact the emerging daily home hemodialysis population; provider incentives for this therapy are less clear, particularly as related to training. A more detailed assessment of the bundled payments is presented in Chapter Ten, and in future ADRs the USRDS will continue to assess the impact of this payment system on the ESRD population. » Figure 1.1.

CHAPTER 7

As of September, 2008, 26 million Medicare-enrolled elderly and
disabled people, as well as individuals with ESRD, were enrolled in
a Medicare Part D prescription-drug plan (PDP). Before 2006, these
patients obtained prescription drug coverage through various insur-
ance plans, state Medicaid programs, or pharmaceutical-assistance
programs, received samples from physicians, or paid out-of-pocket.
After 2006, however, the majority obtained Part D coverage. As
shown on the next page, 58–59 percent of elderly CKD and general
Medicare patients were enrolled in Part D in 2008, compared to 72,
61, and 53 percent of hemodialysis, peritoneal dialysis, and kidney
transplant patients.
The retiree drug subsidy, designed to encourage employers to
supply prescription coverage to Medicare-covered retirees that is
at least as valuable as the Medicare Part D standard plan, provides
employers with a tax-free rebate for 28 percent of retirees’ drug
costs. Other patients are enrolled in employer group health plans or
government/military plans (“creditable coverage”) which provide cov-
erage that is equivalent to or better than Part D.
The proportion of patients with no known source of drug cover-
age is highest in the peritoneal dialysis and transplant populations.
Given that many of these patients are employed, it is likely that some
have sources of prescription drug coverage not tracked by Medicare.
Prior to the start of the Medicare Part D program in 2006, patients
dually-enrolled in Medicare and Medicaid received prescription ben-
efits under state Medicaid programs. The Part D program, however,
offers a substantial low-income subsidy (LIS) benefit to enrollees with
limited assets and income, including those who are dually-enrolled.
The LIS provides full or partial waivers for many out-of-pocket cost-
sharing requirements, including premiums, deductibles, and copay-
ments, and provides full or partial coverage during the coverage gap
(“donut hole”). Compared to patients in the general Medicare popu-
lation, a higher proportion of dialysis, transplant, and elderly CKD
patients receive LIS benefits, and thus, in general, pay proportionally
lower out-of-pocket costs for their Part D prescriptions.
Part D does not cover every medication prescribed to Medicare
enrollees. Several drug categories — including over-the-counter
medications, barbiturates, benzodiazepines, anorexia and weight
loss or gain medications, prescription vitamins (except for prenatal
vitamins), and cough and cold medications — are excluded from the
Part D program by law.
The Medicare Part D program works in concert with Medicare
Part B, which covers medications administered in physician offices
(e.g. erythropoiesis stimulating agents (ESAs) in CKD patients), those
administered during hemodialysis (e.g. ESAs, intravenous vitamin D
and iron products, IV antibiotics, and resuscitative medications), and
most immunosuppressant medications required in the three-year
period following a Medicare-covered kidney transplant. Medicare-
covered transplant patients lose eligibility for Part B benefits after
three years, but, if they become Medicare-eligible due to age or dis-
ability, they again become eligible for Part B for immunosuppressant
coverage. Patients whose kidney transplant is not covered by Medi-
care, but who become Medicare-eligible due to age or disability, can
enroll in and receive their immunosuppressant medications through
Part D. Prescription drugs not covered for beneficiaries under Part B
may be covered by Part D, but coverage depends on whether the
drug is included on the plan formulary.
Part D benefits can be managed through a stand-alone PDP or
through a Medicare Advantage (MA) plan, which provides medical
as well as prescription benefits. The majority of dialysis and trans-
plant patients are covered through PDPs (as patients may not enroll
in Medicare Advantage after ESRD onset), but data in this chapter
encompass both types of plans. » Figure 6.1. Point prevalent Medicare enrollees alive on January 1,

Beginning in 2003, more than 100,000 U.S. patients have begun chronic dialysis each year. Although dialysis is a life-saving treatment, death rates on dialysis have historically been much higher than in the general population.
WorldKidney DayMarch 12, 2015
Since 2003, however, dialysis patients have been living longer. One-year survival after dialysis initiation has improved for 8 consecutive years.

The Peer Kidney Care Initiative (“Peer”) is a collaboration among 13 dialysis providers: American Renal Associates, Atlantic Dialysis Management Services, Centers for Dialysis Care, DaVita HealthCare Partners, Dialysis Clinic, Inc. (DCI), DSI Renal, Fresenius Medical Care, Independent Dialysis Foundation, Northwest Kidney Centers, Renal Ventures Management, Satellite Healthcare, The Rogosin Institute, and U.S. Renal Care.
The goal of Peer is to conduct and disseminate research that is important to all stakeholders in the dialysis community, including patients, physicians, provider organizations, payers, and state and federal governments. As a part of its outreach, Peer is dedicated to the translation of research findings to the clinical setting, with the aim of improving the quality of dialysis patient care.
Steadilyimprovingsurvival
among successive waves of new dialysis patients from 2004 to
2011 has resulted in

In patients who began dialysis in
2006 and 2007 and have been followed
into 2012, almost 40,000 years of life have been
gained, relative to the survival of counterparts beginning dialysis in 2003.

The CDC’s Hemodialysis BSI Prevention Collaborative recommends the following interventions to prevent bloodstream infections in outpatient dialysis units:• monthly observations of opportunities for
hand hygiene, and the sharing of results with staff
• quarterly observations of vascular access care and adherence to aseptic technique
• staff training and competency evaluation
• patient education/engagement, with standardized training on preventing infections
• efforts to reduce catheter use and address barrriers to permanent vascular access placement
• use of chlorhexidine for skin antisepsis
• disinfection of catheter hubs
• application of antimicrobial ointment or povidone-iodine ointment to catheter exit sites during dressing changes

Hospitalizations for dialysis access infection are lowest in the winter,
& peak in
the summer
Possible reasons for this peak include bacterial growth in
pools, lakes, and wells, and the impact of perspiration on bacterial growth.

Published research offers no definitive conclusion about the efficacy of warfarin for stroke prevention in dialysis patients with atrial fibrillation. Most data, however, suggest that warfarin use does increase the risk of bleeding.4,5
New oral anticoagulants such as dabigatran, rivaroxaban, and apixaban have been tested in the general population, but the safety of these agents in dialysis patients is not entirely clear, based on an early report of observational data.6

1861 Thomas Graham coins the word “dialysis,” from the Greek “dia,” meaning through, and “lysis,” to loosen. He also creates the Hoop dialyzer, tying parchment around a hoop floating in water. Into this hoop dialyzer he places solutions of colloids and crystalloids, and demonstrates that only crystalloids pass through the membrane.
1855 German physiologist Adolph Fick uses membranes made from collodion, which allow diffusion of small particles, and proposes the quantitative laws of diffusion.
1854 Scottish chemist Thomas Graham presents a paper entitled “On Osmotic Force,” describing the principles of solute transport across a semipermeable membrane. Having founded the study of colloids, he is widely regarded as the father of colloidal chemistry.
1923 German physician Heinrich Necheles develops a “sandwich” technique to increase the surface area of a dialyzer membrane in relation to blood volume, ultimately increasing dialysis efficiency.
1914 Charles von Hess and Hugh McGuigan, at Northwestern University, improve the efficiency of the vividiffusion apparatus by creating pulsatile flow through the celloidin tubes, thus inhibiting clotting. They also introduce the use of a turbulant flow dialysis fluid around the dialyzing tubes, a principle still used in modern dialysis.
1913 At Johns Hopkins University, John Able, Leonard Rowntree, and BB Turner devise a vividiffusion apparatus they call an “artificial kidney,” which consists of a series of tubes made of celloidin contained in a glass jacket filled with saline or artificial serum. They describe a method “by which the blood of a living animal may be submitted to dialysis outside the body and again returned to the natural circulation.”
1956 Dr. Frank Parsons installs a Kolff-Brigham rotating drum dialysis machine in the Leeds’ General Infirmary, establishing the first artificial kidney unit in the UK. With development help from Willem Kolff, the first pre-sterilized, disposable coil dialyzer is made commercially available by Baxter Laboratories.
1952 During the Korean war, Colonel Paul Techan reports use of the Kolff-Bringham Drum Kidney for treating severely injured troops.
1948 Using stainless steel, researchers at Peter Bent Brigham Hospital in Boston develop the Kolff-Brigham rotating drum kidney. At Mount Sinai Hospital in New York, Drs. Alfred Fishman and Irving Kroop use a a Kolff machine to perform the first human dialysis in the United States.
1947 Swedish physician Nils Alwall develops the first dialyzer with controllable ultrafiltration, creating the first truly practical device for hemodialysis.
1946 At Case Western Reserve University in Ohio, Leonard Skeggs and Jack Leonards develop a large-surface multichannel dialyzer using two sheets of membrane sandwiched between two rubber pads, reducing blood volume and assuring a uniform distribution of blood accross the membrane.
1945 Canadian surgeon Gordon Murray designs a static coil dialyzer, with cellophane tubing wound around a steel frame, and is credited with the first successful use of an artificial kidney machine in North America.
1943–1945 In the Netherlands, Willem Kolff constructs the first modern drum dialyzer. In 1945, a 67 year-old woman in a uremic coma becomes the first patient successfully treated with the Kolff dialyzer.
1962 The first outpatient dialysis unit opens in Seattle.
1960 Norwegian Fredrik Kiil modifies a Skeggs-Leonard dialyzer and develops the Kiil parallel-plate dialyzer, increasing solute clearance efficiency.
1993 The Renal Physicians Association publishes “Clinical Practice Guidelines on Adequacy of Hemodialysis,” defining acceptable methods for measuring hemodialysis adequacy (urea kinetic modeling) and a minimum acceptable level of hemodialysis dose (Kt/V=1.2, or a urea reduction ratio of 65%).
1980s High-efficiency therapies (hemodialysis, hemofiltration, hemo-diafiltration, and high-flux dialysis) are introduced, yielding shortened dialysis times. Ultrafiltration control systems are incorporated into hemodialysis delivery systems allowing precise fluid removal and safe use use of hemodialyzers with high ultrafiltration coefficients.
1985 Drs. Frank Gotch and John Sargent present a mathematical description of urea kinetics (Kt/V), establishing the measurement as an important marker of clinical outcomes.
1981 The National Cooperative Dialysis Study (NCDS) establishes that average urea concentration and protein catabolic rate (PCR) are important factors in determining morbidity and mortality in hemodialysis patients, and that a higher dialysis dose results in reduced morbidity.
1964 Richard Stewart and colleagues at Dow Chemical Company develop the first capillary dialyzer, with hollow fiber membranes made from deacetylated cellulose di-acetate.
1896 Mathieu Jaboulay and Eugene Briau (Lyon, France) and John Murphy (Chicago) use experimental techniques for repair or anastomosis of blood vessels, laying the foundation for dialysis vascular access.
1902 French surgeon and biologist Alexis Carrel publishes on the three-point end-to-end and side-to-side blood vessel anastomosis techniques.
1916 Working under WH Howell at Johns Hopkins University, medical student Jay McLean isolates heparin from canine liver cells. Howell coins the term “heparin” two years later.
1935 The first human trials of heparin begin in May, 1935. By 1937 it is clear that heparin is a safe, easily-available, and effective blood anticoagulant.
1947 At Michael Reese Hospital in Chicago, MR Malinow and W Korzon pioneer methods of fluid removal from the blood of uremic animals using negative pressure.
1949 Swedish physician Nils Allwall conducts experiments on vascular access using rubber tubing and a glass cannula device to connect an artery and vein, but results are unsuccessful.
1960 In Seattle, Belding Scribner, Wayne Quinton, and David Dillard advance the arteriovenous shunt, using silastic tubes fitted with Teflon tips. This shunt provides continuous circulation of the blood when the patient is not attached to the machine, effectively eliminating clotting, providing ready access for repeated long-term hemodialysis, and opening the door to chronic renal replacement therapy.
1961 In London, Stanley Shaldon introduces the temporary femoral vein catheter for use in acute and chronic dialysis.
1966 Brescia, Cimino, Appel, and Hurwich describe a native arteriovenous fistula for chronic vascular access, generally created by an end-to-side vein-to-artery anastomosis. A mature native AV fistula is by far the safest and longest lasting vascular access for hemodialysis.
1973 T Buselmeier and colleagues introduce a new subcutaneous shunt.

Dialyzer typesCoil dialyzer The first single use hemodialyzer. Early designs used a tubular mem-brane supported by a fibrous mesh wound around a central core. Use of the coil dialyzer gradually declined as more efficient hemodialyzer designs evolved. Single uSe flat Plate dialyzer Dialyzers of this type consist of membrane sheets sup-ported on either side by rigid plastic plates. During the early 1960s, these types of dialyzers (Kiil) were considered non-disposable, with only the membrane and blood ports requiring replacement. The Gambro-Alwall diayzer was the first commerically produced device of this type exhibiting a greatly reduced physical size. Hollow fiber dialyzer Present designs of the hollow fiber hemodialyzer can be traced back to experimental designs in the early 1960s from the Cordis Dow Chemical Company, consisting of regenerated cellulosic hollow fibers. Until 1975, these were the only commercially available fibers for use in hemodialyzers. Since 1975, more refined hol-low fiber dialyzers using modified cellulosic and synthetic membranes have become available. HigH flux dialyzer Dialyzers of this type are the newest generation of the hollow fiber dialyzers, constructed of synthetic membranes that offer larger pore sizes for increased middle molecule clearance and higher ultrafiltration coef-ficients, and said to be more biocompatible than their low-flux counterparts.
1744–1745 Christopher Warrick and the Reverend Stephan Hales introduce peritoneal lavage for the treatment of severe ascites. 1877 German investigator G Wegner reports on animal experiments involving the perfusion of the abdominal cavity with cold saline, and determines the absorption rates of various solutions from the peri-toneum. 1894 English physiologist EH Starling and cohorts confirm the work of Wegner and describe the fluid removal characteristics of the peritoneum. 1923 Georg Ganter performs the first clinical application of peritoneal dialysis. 1930s Peritoneal dialysis remains relatively unknown as a treatment for uremia, with clinicians lacking knowlege about its efficiency and procedural issues such as optimal flows and perfusion fluid concentrations. 1946 Boston physicians Howard Frank, Arnold Seligman, and Jacob Fine report a successful application of peritoneal irrigation on a patient with severe uremia. 1959 Intermittent peritoneal dialysis gradually be-comes a safe and standardized technique thanks to the pioneering work of groups headed by PD Doolan and MH Maxwell. 1959 The first case of chronic, irreversible renal failure is successfully treated with intermittent peritoneal dialysis (IPD). 1962 ST Boen and colleagues introduce the automatic cycling machine, making periodic peritoneal dialysis far more dependable. 1964–1966 Semiautomatic peritoneal dialysis cycler machines are used to treat patients. Boen publishes the first textbook on PD for use in clinical medicine. 1965 Recirculation peritoneal dialysis is introduced. 1968 The Tenckhoff in-dwelling catheter, which allows long-term access to the abdominal cavity, is introduced. 1972 Closed loop, reverse osmosis automatic peritoneal dialysis machines are introduced. 1976 J Moncrief and R Popovich propose the kinetics of continuous ambulatory peritoneal dialysis (CAPD). 1978 Reciprocating, fresh fluid semicontinuous PD is introduced, aimed at improving peritoneal clearance. 1981 JA Diaz Buxo and FF Adams introduce continuous cyclic peritoneal dialysis (CCPD).

■ Executive summary
The United States Renal Data System constitutes the most comprehensive database of end-stage renal disease—and now of chronic kidney disease as well—in the world, serving a major public health role by documenting patients with these diseases and advancing their treatment. Under NIH direction, the USRDS has produced major studies addressing changes in disease rates, defining pre-ESRD care, developing methods to define the recognized CKD population, assessing prescription drug therapy, determining the frequency and quality of preventive care and risk factor monitoring, defining care by large ESRD providers, and assessing outcomes.
In the last seven years, under the direction of investigators from the Minneapolis Medical Research Foundation (MMRF), the USRDS has implemented substantial changes in the registry’s focus, addressing Healthy People 2010 objectives while also de� ning the potential growth of the renal program and its implication for the U.S. healthcare system. In the 2005 Annual Data Report (ADR), for instance, the Coordinating Center (CC) demonstrated the multiplying e� ects of kidney disease, illustrating how its interaction with diabetes and cardio-vascular disease impacts the healthcare budget in the U.S. and around the world. � e CC has also played a central role in working with the Special Studies Centers (SSCs), addressing � eld operations for data collections, providing database and technical support, and de� ning the strengths and weaknesses in past and future plans for such studies.
Our proposal to continue serving as the CC advances the high standards set by the previ-ous contractor and by ourselves. We describe advanced disease rate mapping to depict varia-tions in care, enhanced data access, major new initiatives in preventive care, documentation of the recognized CKD population, an expanded Internet website with dynamic and real-time data access, and our extensive attention to data quality and consistency, and provide a criti-cal assessment of analytical methods. And we present an outstanding group of investigators. We propose new approaches to expand and disseminate USRDS information from the ADR, journal publications, presentations, and government-requested information, using enhanced web applications. Our administrative approach will continue to expand documentation of the operational elements of the USRDS and enhance the open access to USRDS activities, meth-ods, and systems under the direction of the NIH, the oversight committees, and the ESRD community.
■ Introduction to the objectives
of the USRDS
The original five goals of the USRDS have this year been expanded to eight, broadly defining the major functions of the registry. In its first ten years, the USRDS focused on descriptive characteristics of the ESRD population and on comparative event rates. In the last seven years,

NIH-NIDDK-06-01 Ful� lling the objectives of the USRDS
USRDS Investigative Team 2
our investigative team has broadened the scope of the USRDS to address clinical care, improve access to data, expand disease mapping of variations in care and events, develop the pre-ESRD and CKD databases, and advance the administrative operations. Our proposal illustrates our commitment to expand and further this work, including, for example, investigations into dis-parities in care within the kidney disease population.
■ Objective A Characterize the
ESRD patient population
In our work as the CC of the USRDS we have addressed this goal in great detail, paying increased attention to the major causes of ESRD and to trends in disease rates by age, gender, and race. We have also introduced geo-mapping of the data, further developing advanced statistical methods to illustrate geographic differences in disease rates and patterns of care. Additional information on the level of counties and Metropolitan Statistical Areas (MSAs) is needed to provide detail on high concentrations of disease.
� e declining incident rates of ESRD seen in most populations, for example, are not present in younger African Americans. � is trend may be more pronounced in certain geographic areas, and merits investigation, as does the care these populations receive. To address these issues, we propose to use the extensive geomapping techniques developed by the CC to more closely examine regions with a high frequency of disease, such as the southern states and inner cit-ies on the East Coast. � e increasing burden of diabetes in the general population is a related concern, particularly since it disproportionally a� ects a number of racial and ethnic groups. A more detailed investigation is needed of the growth in diabetes overall and as it relates to ESRD incident rates and access to care.
� e new CMS 2728 form (the Medical Evidence form for ESRD enrollment), which was revised in 2004 and implemented the following spring, added data � elds on patient access to care. � e form now collects information on pre-ESRD care by a nephrologist and kidney dietician, on treatment with exogenous erythropoietin, and on the type of � rst outpatient vascular access. Each of these elements further illustrates the care given in the pre-ESRD period, and may pro-vide insight into racial disparities in incident rates. � e details we have outlined under Task Two identify ways to consolidate these data and enhance these comparisons.
In our proposal we also describe new epidemiologic cohorts which will characterize the disease burden in incident and prevalent patients. � ese cohort descriptions will provide expanded information on comorbidity and complications, and will be used to study pre-existing con-ditions associated with future outcomes. We propose to address the care, comorbidity, and access to care among working adults in employer group health plan (EGHP) populations as well as in elderly Medicare patients, working to determine the di� erences which may in� uence early mortality and morbidity.
Recent years have seen a dramatic consolidation in dialysis providers, with two large chains now treating more than 60 percent of the dialysis population. Smaller provider groups con-tinue to consolidate as well, reducing the number of independent providers. Hospital-based operations still treat approximately one in � ve dialysis patients, yet use widely diverse prac-tices. � ese changes in the provider community need to be addressed on a geographic basis to determine how consolidation may have a� ected care. Some data, for instance, suggest that large dialysis organizations treat fewer patients with home dialysis than do hospital-based operations. To illustrate access to alternative dialysis therapies, and to evaluations for the transplant wait-list and for transplantation itself, these � ndings need to be explored.
We also address the expanded demand for data, particularly on disparities in access to care, through enhancements to RenDER, our web-based on-line data query system. � e basic sys-tem currently addresses incidence, prevalence, and mortality. To help enhance public health oversight of the care system, we will further develop the system’s provision of geomapped data, allowing users to drill down to various cities and MSAs.

■ Objective B Describe the
prevalence & incidence rates
of kidney diseases that lead to ESRD
In the Annual Data Report (ADR) the CC has developed special sections addressing diseases beyond diabetes and hypertension. These rare conditions include Alport’s disease, polycys-tic kidney disease, Fabry’s disease, multiple myeloma, and other inflammatory diseases. New treatments have been developed for some of these rare diseases, such as the enzyme replace-ment therapy now used to treat Fabry’s. Patient outcomes have received little attention, but should be assessed in depth, and the USRDS database contains the largest amount of data on these cases collected in one place. Immunologic disorders such as systemic lupus erythemato-sus, Wegener’s granulomatosis, and ANCA-positive vasculitis, with their associated complica-tions, are also rare but important diseases to track over time.
Most attention related to ESRD incidence has centered on the concept that kidneys progres-sively lose function over time. Emerging data, however, suggest that many patients su� er epi-sodes of acute kidney failure prior to the start of ESRD treatment. Some data suggest that acute kidney failure in a hospital setting may re� ect undiagnosed CKD manifesting itself dur-ing an acute medical complication. � e recent increase in hospitalizations which list acute kidney failure as a complication or primary cause of stay suggests that this event merits greater attention, with analyses to determine how patients are followed and their potential to progress to ESRD.
It is important to track the comorbidity of patients entering ESRD treatment, as their com-plexity in� uences subsequent survival time under ESRD care. � e CC has created methods to identify this comorbidity, addressing patterns of hospitalizations and associated medical con-ditions in Medicare patients age 65 and older, and evaluating the services they receive in the two years prior to starting ESRD care. � is approach has provided signi� cant information on the older population, but little on those younger than 65. Now that CC’s ESRD database con-tains six years of Medstat data, however, we can also begin to examine data on EGHP patients, who are primarily younger than 65, looking back from the date of ESRD or regular dialysis services to determine the level of comorbidity carried in the past. � ese di� erent approaches should be advanced to assess long-term trends in adjusted ESRD incidence, prevalence, and mortality.
Comorbidity in the prevalent population is a particularly challenging issue, since data are not collected on a sample of ESRD or dialysis patients over time. � e CC has developed methods (incorporating the approach of Hebert et al.) for assessing an individual’s comorbidity using medical claims for services. We have also performed a more comprehensive validation study, which should help address the complexity of the existing population and its outcomes. To assess care and risk factor interventions, however, it would be very helpful to have biochemical data on both the incident and prevalent populations. CMS, with support from the ESRD networks and large dialysis organizations, is considering obtaining monthly biochemical data on the dialysis population to assess the e� ectiveness of medical interventions. � ese data would be very impor-tant, since classic outcome studies—assessing, for example, associations of mortality with the use of intravenous vitamin D—would be enhanced with access to data on calcium, phosphorus, and parathyroid hormone levels. So that the e� ectiveness of risk factor interventions and their associated outcomes may be addressed, these biochemical data need to be made available.

The USRDS ADR has documented significant changes in the use of ESRD treatment modali-ties. The use of peritoneal dialysis in incident patients, for example, has declined steadily, so that the prevalent peritoneal dialysis population is down to 25,000 from a high of 35,000 just a decade ago. While these changes may reflect new perceptions about the therapy and its long-term complications, little is known about why utilization rates for the major dialytic modali-ties have changed so dramatically.
Considerable attention has recently been paid to daily home or in-center hemodialysis as a method to increase the total delivered therapy, and to thereby improve control of � uid over-load and other complications. Since there is no registration system for the di� erent types of
