What is a System of Excellence in healthcare?
A System of Excellence is an integrated, multidisciplinary care model that combines clinical protocols, data analytics, patient education, and coordinated provider teams to manage chronic diseases at the population level. In diabetes and kidney disease, these systems use risk stratification, proactive outreach, and evidence-based pathways to prevent complications before they occur, rather than treating crises after they develop.
What is population health management?
Population health management (PHM) is the systematic process of identifying, stratifying, and proactively managing the health of a defined group of people to improve outcomes and reduce costs. In chronic disease, PHM uses electronic health record data, registries, and predictive analytics to find high-risk patients, coordinate care across providers, and close gaps in screening and treatment before disease progresses.
Why are diabetes and kidney disease linked?
Chronically elevated blood glucose damages the tiny blood vessels (glomeruli) in the kidneys that filter waste from blood. This injury, called diabetic nephropathy, is the most common cause of chronic kidney disease and kidney failure worldwide. Roughly 40% of people with type 2 diabetes develop CKD. High blood pressure, a frequent companion of both conditions, accelerates the damage further by increasing pressure within the filtering units.
How can health systems reduce kidney failure?
Health systems can significantly reduce kidney failure by implementing three proven strategies: universal CKD screening in all diabetes patients using urine albumin-to-creatinine ratio (UACR) and eGFR tests; aggressive blood pressure and glucose control using medications proven to protect kidneys (SGLT2 inhibitors, RAAS blockers); and multidisciplinary care teams that coordinate nephrology, endocrinology, nutrition, and social support. Early detection and treatment can slow or stop CKD progression.
What role does multidisciplinary care play in CKD management?
Multidisciplinary care teams — combining nephrologists, diabetologists, dietitians, pharmacists, social workers, and care coordinators — consistently produce better outcomes than single-provider management. Evidence shows that multidisciplinary CKD clinics reduce time to kidney failure, improve blood pressure and anemia control, increase rates of planned dialysis initiation, and reduce emergency hospitalizations compared to usual care.
90% of people with CKD do not know they have it. Because early kidney disease causes no symptoms, routine screening in high-risk groups — people with diabetes, hypertension, or a family history of kidney disease — is the only reliable way to detect it before significant, irreversible damage occurs.

Milestone Breakthrough Policy Shift
Breakthrough
The convergence of artificial intelligence and novel therapeutics has created the most powerful era in diabetes and kidney disease management. Machine-learning models trained on electronic health record data now predict CKD progression years before clinical signs appear, enabling proactive intervention. The FLOW trial published in NEJM in 2024 demonstrated that semaglutide (Ozempic/Wegovy) reduced major kidney events by 24% in people with type 2 diabetes and CKD — a result that extends the kidney-protective drug class beyond SGLT2 inhibitors to GLP-1 receptor agonists. Remote patient monitoring programs now continuously track blood pressure, glucose, and weight, alerting care teams to deterioration in real time. Natural language processing extracts CKD risk signals from clinical notes that structured data misses, and predictive risk scores automatically trigger outreach to patients who are overdue for kidney screening. Health systems using these tools have demonstrated 25–40% improvements in UACR testing rates and significant reductions in unplanned CKD-related hospitalizations.
Policy
The Inflation Reduction Act (IRA) of 2022 capped Medicare insulin copays at $35 per month — a landmark change for the estimated 8.4 million Americans using insulin, many of whom had been rationing doses because of cost. The law also empowered CMS to negotiate drug prices for the first time and extended Affordable Care Act subsidies. For people with diabetes, cost has long been a driver of non-adherence and poor glycemic control that accelerates kidney disease. Simultaneously, the CMS Innovation Center expanded kidney care payment models under the Kidney Care Choices (KCC) Model, incentivizing health systems to delay dialysis and increase home dialysis and transplantation rates. The IRA also accelerated adoption of remote therapeutic monitoring codes, enabling reimbursement for AI-powered care management platforms.
Turning Point
The COVID-19 pandemic produced a paradox for chronic disease management. On one hand, telehealth visits for diabetes and CKD management increased by over 4,000% between 2019 and 2020 as CMS rapidly waived restrictions on virtual care. This permanently expanded care access for rural and underserved patients who previously traveled hours for nephrology appointments. On the other hand, COVID-19 caused direct acute kidney injury in up to 36% of hospitalized patients, with CKD and diabetes dramatically increasing risk of severe illness and death. Patients with CKD and diabetes had 5–10 times the mortality risk from COVID compared to those without chronic disease. The pandemic also revealed stark racial disparities in CKD and diabetes outcomes, with Black, Hispanic, and Indigenous populations experiencing disproportionate mortality — driving policy attention to health equity in population health programs.
Breakthrough
The CREDENCE trial, published in New England Journal of Medicine in April 2019, was the most significant advance in CKD treatment in two decades. Canagliflozin (Invokana), an SGLT2 inhibitor primarily approved for type 2 diabetes, reduced the combined risk of kidney failure, doubling of serum creatinine, and death from kidney or cardiovascular disease by 30% compared to placebo in people with type 2 diabetes and CKD stages 2–3. The trial was stopped early because the benefit was so clear it would have been unethical to continue the placebo group. This followed the 2015 EMPA-REG OUTCOME trial and 2016 CANVAS trial, which had first revealed unexpected kidney-protective effects of this drug class. The DAPA-CKD trial (2020) then extended SGLT2 protection to patients with CKD who did not have type 2 diabetes — fundamentally repositioning these as kidney drugs, not just diabetes drugs.
Policy
The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 created the Quality Payment Program (QPP), the most sweeping restructuring of physician payment in Medicare history. MACRA replaced the sustainable growth rate formula with two pathways: the Merit-based Incentive Payment System (MIPS) and Advanced Alternative Payment Models (APMs). For the first time, physician reimbursement was explicitly tied to quality metrics, cost efficiency, and improvement activities — including diabetes HbA1c control and CKD care coordination. Comprehensive Primary Care Plus (CPC+) and Accountable Care Organizations (ACOs) became primary vehicles for population health management. By 2018, over 10 million Medicare beneficiaries with diabetes were covered by some form of value-based care arrangement, and health systems began investing heavily in chronic disease registries, care management software, and multidisciplinary care teams to meet quality benchmarks.
Milestone
In 2012, the international Kidney Disease: Improving Global Outcomes (KDIGO) organization published updated CKD clinical practice guidelines that introduced the landmark prognosis “heat map” — a color-coded risk matrix combining six eGFR categories (G1–G5, with G3 split) and three albuminuria categories (A1–A3). This gave clinicians worldwide a universal visual tool for assessing CKD risk and guiding referral and treatment intensity. The CKD Prognosis Consortium, published simultaneously in Lancet, provided the epidemiological foundation with data from over 1.5 million patients. The guidelines also standardized the definition of CKD as kidney damage or eGFR below 60 mL/min for more than three months — eliminating inconsistency in diagnosis. For population health programs, the heat map became the standard framework for risk stratification.
Policy
The Patient Protection and Affordable Care Act (ACA) of 2010 created the legal and financial infrastructure for population health management in the United States. It established the Center for Medicare and Medicaid Innovation (CMMI) to test new payment and delivery models, created the Medicare Shared Savings Program for Accountable Care Organizations, and mandated that preventive services — including diabetes and CKD screening — be covered without cost-sharing. For chronic disease management, the ACA’s expansion of Medicaid to cover low-income adults dramatically expanded coverage for populations with high rates of diabetes and CKD. The ACA also established the National Quality Strategy and Patient-Centered Outcomes Research Institute (PCORI), directing millions of dollars toward comparative effectiveness research in diabetes and kidney disease management that would shape clinical guidelines for the next decade.
Milestone
Analysis of the Third National Health and Nutrition Examination Survey (NHANES III) published in 2001 provided the first nationally representative estimate of CKD prevalence in the US — revealing that approximately 11% of the adult population (19.2 million people) had CKD, the vast majority undiagnosed. This data catalyzed a national public health response and underpinned NKF’s advocacy for universal screening. The NHANES findings, combined with UKPDS long-term follow-up data (2007) demonstrating the legacy effect of early glucose control, shaped the next generation of clinical guidelines. The Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial (2008) then cautioned against overly aggressive glucose lowering in high-risk type 2 diabetes patients — an important nuance showing that population-level strategies must be individualized, not uniform.
Milestone
The National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative (KDOQI) published its first comprehensive clinical practice guidelines for chronic kidney disease in 2002, but the program was established in 1997. KDOQI created a common language and framework for CKD care that did not previously exist: it defined the five stages of CKD based on glomerular filtration rate (GFR), recommended laboratory thresholds for diagnosis, and specified evidence-based targets for blood pressure, anemia, nutrition, and cardiovascular risk. Before KDOQI, CKD management was fragmented, inconsistent, and largely reactive. KDOQI transformed it into a standardized, proactive discipline. Earlier KDOQI guidelines for dialysis adequacy (1997) and anemia management established the pattern of guideline-driven practice that the CKD module completed. These guidelines were adopted internationally and became the model for KDIGO’s global guidelines.
Breakthrough
The UK Prospective Diabetes Study (UKPDS), published in British Medical Journal in September 1998, was the definitive landmark trial for type 2 diabetes management. Running for 20 years across 23 UK centres and enrolling 5,102 patients, UKPDS demonstrated that tight blood pressure control (mean 144/82 vs. 154/87 mmHg) reduced diabetes-related deaths by 32%, strokes by 44%, and microvascular complications — including kidney disease — by 37%. Intensive blood glucose control reduced microvascular complications by 25% and showed a trend toward reduced kidney failure. Crucially, UKPDS also demonstrated that the glucose-lowering effect of sulphonylureas and insulin showed no difference in macrovascular outcomes from metformin — establishing metformin as the preferred first-line agent. UKPDS became the evidence base for the first evidence-based diabetes guidelines and directly shaped KDOQI’s recommendations for blood pressure management in diabetic CKD.
Breakthrough
The Diabetes Control and Complications Trial (DCCT), published in New England Journal of Medicine in September 1993, was the most important clinical trial in the history of type 1 diabetes. The 10-year trial enrolled 1,441 participants and demonstrated that intensive insulin therapy reducing HbA1c from 9.0% to 7.2% cut the risk of new kidney disease (microalbuminuria) by 39% and slowed progression to more severe nephropathy by 54%. It also reduced retinopathy risk by 76% and neuropathy by 60%. Before DCCT, it was debated whether complications were inevitable or whether glucose control could prevent them. DCCT settled that debate conclusively. The subsequent EDIC (Epidemiology of Diabetes Interventions and Complications) follow-up study extended the observation period to over 30 years, demonstrating that the early period of intensive control produced a metabolic “memory” that protected against kidney failure even after treatment was equalized — the “legacy effect.”
Milestone
The 1980s saw the emergence of systematic, protocol-driven diabetes management. The National Diabetes Data Group’s 1979 classification of diabetes types provided the standardized diagnostic framework that enabled consistent research and care. The Diabetes Control and Complications Trial began enrollment in 1983. The Minnesota Chronic Disease Demonstration Project (1982–1986) was among the first programs to demonstrate that a structured, team-based approach to chronic disease management could meaningfully improve outcomes at the population level. Kaiser Permanente and Group Health of Puget Sound began building chronic disease registries in the mid-1980s — systems that tracked individual patient status and triggered proactive outreach, prefiguring modern population health management platforms. The Indian Health Service launched targeted diabetes programs for Native American populations during this period, recognizing the disproportionate burden in these communities.
Milestone
The modern era of chronic disease management began not in a clinic, but in a cohort. The Framingham Heart Study, launched in 1948 and reporting its landmark cardiovascular risk factor findings through the 1960s–70s, introduced the methodology of prospective cohort epidemiology — following populations over time to identify disease risk factors before symptoms appear. The National Health and Nutrition Examination Survey (NHANES), beginning in 1971, systematized population-level health surveillance for the entire United States. The CDC created the National Diabetes Surveillance System in 1977, providing the first continuous national tracking of diabetes incidence and prevalence. These surveillance systems made it possible to quantify the diabetes epidemic, identify high-risk groups, and measure whether public health interventions were working — the foundational capability of all population health management. The end-stage renal disease (ESRD) Medicare benefit, created by Congress in 1972, was the first disease-specific health coverage expansion and revealed the full scale of kidney failure as a public health crisis.
Founded 1950, the NKF launched KDOQI in 1997 — the first evidence-based CKD guidelines — and continues to drive clinical standards, public awareness, and organ donation advocacy. The NKF’s CKD staging system is the foundation of modern kidney care management worldwide.
The CDC’s National Diabetes Prevention Program (DPP), launched nationally in 2010, has enrolled 2 million+ people at risk of type 2 diabetes in evidence-based lifestyle programs that reduce diabetes incidence by 58%. The CDC also operates the National CKD Surveillance System and manages the National Diabetes Surveillance System.
The NIH funded the landmark DCCT (1983–1993), ACCORD, LOOK AHEAD, and CREDENCE trials that define evidence-based diabetes and CKD management. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) is the primary NIH institute funding diabetes and kidney disease research, with an annual budget exceeding $2 billion.
The ADA publishes Standards of Care in Diabetes annually — the most widely used clinical practice guidelines for diabetes management globally. Its 2023 and 2024 standards explicitly elevated SGLT2 inhibitors and GLP-1 receptor agonists to first-line therapy for patients with diabetes and CKD, regardless of glucose control needs.
KDIGO develops and updates international CKD clinical practice guidelines. Its 2012 CKD classification system — the heat map of eGFR and albuminuria categories — is the universal standard for CKD risk stratification. KDIGO’s 2022 Diabetes and CKD guideline update was the first to integrate SGLT2 inhibitors, GLP-1 agents, and finerenone into a unified care pathway.
The IHS serves 2.6 million Native Americans and Alaska Natives — populations with among the world’s highest rates of diabetes and diabetic kidney disease. IHS diabetes programs, including the Special Diabetes Program for Indians (SDPI) funded since 1997, have demonstrated dramatic reductions in diabetes-related complications and CKD progression in participating communities — a model for targeted population health systems.
The WHO’s Global Action Plan for the Prevention and Control of Noncommunicable Diseases sets diabetes and CKD management targets for member nations. WHO’s HEARTS technical package provides low- and middle-income countries with standardized protocols for hypertension management — the primary driver of CKD outside diabetes globally.
CMS covers 80 million Americans and is the single most powerful force in US healthcare payment reform. Its CMMI has tested 54+ payment and delivery models since 2011, including the Kidney Care Choices Model, the Comprehensive ESRD Care Model, and multiple ACO programs that explicitly reward better diabetes and CKD outcomes. CMS quality measures for diabetes and CKD are the de facto national performance standards.

Population health management is the systematic process of identifying, stratifying, and proactively caring for a defined group of patients to improve health outcomes and reduce costs. In diabetes and CKD, it uses electronic health record registries, predictive analytics, and care coordination to find high-risk patients and close gaps in screening and treatment before disease progresses to irreversible stages.
Chronically elevated blood glucose damages the tiny blood vessels (glomeruli) in the kidneys that filter waste. This injury — called diabetic nephropathy — is the most common cause of chronic kidney disease and kidney failure worldwide. Approximately 40% of people with type 2 diabetes develop CKD over time. High blood pressure, which frequently accompanies diabetes, compounds the damage by raising pressure within kidney-filtering units.
Chronic kidney disease is a long-term condition in which the kidneys gradually lose their ability to filter waste, balance fluids, and regulate blood pressure. CKD is staged 1–5 based on estimated glomerular filtration rate (eGFR) and urinary albumin levels. Stage 5 (eGFR below 15) is kidney failure requiring dialysis or transplant. Diabetes and hypertension cause about two-thirds of all CKD cases globally.
CKD prevention in diabetes requires three core strategies: (1) optimal glucose control (HbA1c target typically 6.5–8.0% based on patient risk); (2) blood pressure control below 130/80 mmHg using RAAS blockers (ACE inhibitors or ARBs) as first choice; and (3) use of SGLT2 inhibitors or GLP-1 receptor agonists that provide kidney protection beyond glucose and blood pressure effects. Annual UACR and eGFR screening enables early detection.
Estimated glomerular filtration rate (eGFR) is a blood test calculation that estimates how well the kidneys are filtering waste per minute. Normal eGFR is above 90 mL/min. CKD is diagnosed at eGFR below 60 for more than three months. eGFR is the primary metric for staging CKD severity and guiding treatment decisions, medication dosing adjustments, and referral timing to nephrology specialists.
The urine albumin-to-creatinine ratio (UACR) measures the amount of albumin (a protein) leaking into urine — a sensitive early marker of kidney damage. A UACR above 30 mg/g indicates kidney damage even when eGFR is normal. ADA and KDIGO guidelines recommend annual UACR testing in all people with diabetes. Elevated UACR is both a diagnostic marker and a target for treatment with SGLT2 inhibitors or RAAS blockers.
A System of Excellence is an integrated, multidisciplinary, data-driven care model designed to produce superior outcomes for a defined patient population. In diabetes and CKD management, it combines standardized clinical protocols, population health registries, care coordination teams, patient self-management support, quality measurement, and financial incentives aligned with better outcomes — rather than simply higher volumes of care.
SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin) are a class of diabetes medications that block glucose reabsorption in the kidney, causing excess glucose to be excreted in urine. Beyond glucose lowering, they protect kidneys through hemodynamic mechanisms — reducing intraglomerular pressure and kidney oxygen consumption — independent of glucose control. The CREDENCE (2019) and DAPA-CKD (2020) trials showed 30–39% reductions in kidney failure risk.
KDOQI (Kidney Disease Outcomes Quality Initiative) is the National Kidney Foundation program that created the first evidence-based clinical practice guidelines for CKD in 1997–2002. KDOQI defined the five-stage CKD classification system still used worldwide, established evidence-based targets for blood pressure, anemia, and bone disease management in CKD, and set the global standard for systematic kidney care. It is the foundation of all modern nephrology quality programs.
Value-based care is a payment and delivery model that rewards health systems for achieving better patient outcomes and lower costs rather than simply providing more services. For diabetes and CKD, value-based contracts measure quality metrics like HbA1c control rates, annual kidney screening rates, blood pressure control, and reduction in dialysis starts — creating financial incentives to invest in prevention and care coordination rather than reactive treatment.
A multidisciplinary CKD care team typically includes nephrologists, diabetologists or primary care physicians, dietitians specialized in renal nutrition, pharmacists for medication management, social workers for financial and psychosocial barriers, and care coordinators who manage transitions and follow-up. Evidence shows these teams produce 20–35% slower kidney function decline and dramatically lower rates of unplanned dialysis initiation compared to single-provider care.
ADA 2024 and KDIGO 2022 guidelines recommend annual CKD screening for all people with diabetes using two tests: (1) urine albumin-to-creatinine ratio (UACR) to detect early kidney damage, and (2) serum creatinine-based eGFR to measure kidney filtration capacity. Screening should begin at diabetes diagnosis for type 2 diabetes, and within 5 years of diagnosis for type 1 diabetes. Abnormal results should be confirmed before initiating new therapy.
The FLOW trial, published in New England Journal of Medicine in 2024, was the first dedicated kidney outcomes trial for a GLP-1 receptor agonist. Semaglutide 1.0 mg weekly reduced the risk of a composite kidney outcome (major kidney disease events, kidney failure, or death from kidney or cardiovascular causes) by 24% compared to placebo in adults with type 2 diabetes and CKD. The trial was stopped early due to overwhelming benefit, confirming GLP-1 drugs as a new pillar of CKD management.
The IHS Special Diabetes Program for Indians (SDPI), funded by Congress since 1997, provides grants to 365+ tribal health programs for diabetes prevention and treatment. Despite serving populations with among the highest diabetes rates globally, SDPI-funded programs achieved a 54% reduction in diabetes-related amputations and a 54% decline in kidney failure rates from diabetic nephropathy between 1996–2013 — proof that culturally adapted, systematically delivered population health programs produce dramatic outcomes even in high-risk communities.
The DCCT was a landmark NIH-funded randomized trial (1983–1993) that enrolled 1,441 people with type 1 diabetes to test whether intensive glucose control (HbA1c ~7%) versus conventional control (HbA1c ~9%) prevented complications. Intensive control reduced new kidney disease by 39% and slowed progression by 54%. It proved definitively that complications were preventable — changing the goals of diabetes care from symptom management to complication prevention.
The CDC National DPP is a structured 12-month lifestyle change program for adults with prediabetes or at high risk for type 2 diabetes. Participants receive 16 core sessions with a trained lifestyle coach, focusing on achieving 5–7% weight loss and 150 minutes of weekly moderate physical activity. The original DPP randomized trial (2002) showed 58% reduction in diabetes incidence. Real-world programs consistently replicate this in community settings. Medicare has covered the National DPP since 2018.
Black Americans have 3x the rate of kidney failure from diabetes compared to White Americans. Indigenous populations have the world’s highest rates of diabetic kidney disease. These disparities reflect intersecting factors: higher rates of hypertension and diabetes (partly driven by social determinants of health), reduced access to early specialty care, historical underrepresentation in clinical trials, and structural inequities in healthcare access and quality — not biological differences in disease susceptibility.
Finerenone (Kerendia) is a non-steroidal mineralocorticoid receptor antagonist (MRA) approved by the FDA in 2021 for CKD with type 2 diabetes. Unlike older steroidal MRAs (spironolactone), it has a lower risk of hyperkalemia (high potassium). The FIDELIO-DKD and FIGARO-DKD trials showed it reduces CKD progression and cardiovascular events by 18–26%. KDIGO 2022 guidelines include finerenone as a third kidney-protective agent alongside SGLT2 inhibitors and RAAS blockers.
AI and machine learning are transforming CKD management in four ways: (1) predictive risk models identify high-risk patients 2–3 years before clinical diagnosis; (2) natural language processing extracts CKD risk signals from clinical notes that structured data misses; (3) automated alert systems trigger outreach for patients overdue for screening; (4) clinical decision support tools recommend guideline-adherent medications. The challenge is translating algorithmic predictions into clinical actions through appropriate workflow design.
Hemodialysis costs approximately $90,000–100,000 per patient per year in the United States. The CDC estimates total US diabetes costs at $413 billion annually (2022). CKD costs Medicare approximately $140 billion per year — representing 25% of Medicare spending for 1% of beneficiaries on dialysis. By comparison, the CDC National DPP costs approximately $400–600 per participant and prevents diabetes in over half of completers. Prevention economics favor upstream investment overwhelmingly.
HbA1c (glycated hemoglobin) measures average blood glucose over the past 2–3 months. A normal HbA1c is below 5.7%; prediabetes is 5.7–6.4%; diabetes is 6.5%+. For most people with type 2 diabetes and CKD, ADA 2024 guidelines recommend an HbA1c target of 7–8%, individualized based on age, CKD stage, and risk of hypoglycemia. Note: HbA1c can be falsely low in advanced CKD due to shortened red blood cell lifespan — continuous glucose monitoring may be more accurate in CKD stages 4–5.
Blood pressure above 130/80 mmHg directly damages kidney glomeruli by increasing filtration pressure, accelerating scarring (fibrosis), and reducing kidney reserve. UKPDS (1998) showed that BP control reduced microvascular CKD complications by 37%. Current ADA/KDIGO guidelines recommend a BP target below 120/80 for most adults with diabetes and CKD, using RAAS blockers (ACE inhibitors or ARBs) as preferred agents because they reduce filtration pressure and albumin excretion beyond blood pressure reduction.
The Kidney Care Choices (KCC) Model, launched by CMS in 2022, is a voluntary value-based payment model that incentivizes health systems and physician groups to delay kidney failure, increase home dialysis and kidney transplant rates, and improve care for people with advanced CKD. Over 140 health systems and groups participate. Participants receive per-beneficiary monthly payments for managing CKD patients, replacing the fee-for-service model that previously rewarded more dialysis visits rather than better kidney health.
Renal-diabetic nutrition guidelines recommend: moderate protein intake (0.8 g/kg/day, avoiding high protein diets that increase kidney filtration burden); sodium restriction below 2,300 mg/day to support blood pressure control; potassium management in advanced CKD to prevent dangerous hyperkalemia; phosphorus moderation to prevent bone and cardiovascular complications; and a Mediterranean-style dietary pattern shown in trials to slow both diabetes and CKD progression. A registered renal dietitian is a core member of the CKD care team.
The next decade will bring: widespread AI-powered early detection of at-risk individuals in EHR populations; expanded use of the “four pillars” of DKD therapy (RAAS blockers, SGLT2 inhibitors, GLP-1 receptor agonists, finerenone) proven to protect kidneys through complementary mechanisms; more home-based remote monitoring reducing clinic burden; and health equity-focused population health programs that close racial and socioeconomic gaps in CKD and diabetes outcomes. Gene and cell therapies for diabetic nephropathy are in early clinical trials as longer-term horizons.
