Improving outcomes of dialysis patients by population health management-the Global Chief Medical Officer Initiative

Kidney Health Initiative ESKD Data Standards Project

The end-stage kidney disease (ESKD) Data Standards Project was launched by the Kidney Health Initiative (KHI) with the goal of standardizing dialysis-related measurements for research use. KHI is a public-private partnership between the American Society of Nephrology, US Food and Drug Administration, and organizations with an interest in kidney disease. KHI promotes safe and effective patient-centered therapies for people with kidney disease. In 2018, KHI established a workgroup with expertise in nephrology, nursing, quality management, ESKD data, organizational management, and clinical research. The workgroup identified 5 topic areas and 8 specific measures for the development of standards on the basis of the existing ESKD Measurement Specification Manual published by the Centers for Medicare & Medicaid Services. The topic areas were ultrafiltration rate, vascular access, dialysis small solute clearance (3 data standards), hospitalization (2 data standards), and mortality. The research standards were approved by the workgroup, reviewed by external reviewers, and opened to public comment. The data standards attempt to achieve balance between brevity and completeness in the face of knowledge gaps. The ESKD Data Standards are publicly available on the KHI website (https://khi.asn-online.org/projects/project.aspx?ID=78).

Health Policy for Dialysis Care in Canada and the United States

Contemporary dialysis treatment for chronic kidney failure is complex, is associated with poor clinical outcomes, and leads to high health costs, all of which pose substantial policy challenges. Despite similar policy goals and universal access for their kidney failure programs, the United States and Canada have taken very different approaches to dealing with these challenges. While US dialysis care is primarily government funded and delivered predominantly by private for-profit providers, Canadian dialysis care is also government funded but delivered almost exclusively in public facilities. Differences also exist for regulatory mechanisms and the policy incentives that may influence the behavior of providers and facilities. These differences in health policy are associated with significant variation in clinical outcomes: mortality among patients on dialysis is consistently lower in Canada than in the United States, although the gap has narrowed in recent years. The observed heterogeneity in policy and outcomes offers important potential opportunities for each health system to learn from the other. This article compares and contrasts transnational dialysis-related health policies, focusing on key levers including payment, finance, regulation, and organization. We also describe how policy levers can incentivize favorable practice patterns to support high-quality/high-value, person-centered care and to catalyze the emergence of transformative technologies for alternative kidney replacement strategies.

Cardiovascular outcome trials in patients with chronic kidney disease: challenges associated with selection of patients and endpoints

Although cardiovascular disease is a major health burden for patients with chronic kidney disease, most cardiovascular outcome trials have excluded patients with advanced chronic kidney disease. Moreover, the major cardiovascular outcome trials that have been conducted in patients with end-stage renal disease have not demonstrated a treatment benefit. Thus, clinicians have limited evidence to guide the management of cardiovascular disease in patients with chronic kidney disease, particularly those on dialysis. Several factors contribute to both the paucity of trials and the apparent lack of observed treatment effect in completed studies. Challenges associated with conducting trials in this population include patient heterogeneity, complexity of renal pathophysiology and its interaction with cardiovascular disease, and competing risks for death. The Investigator Network Initiative Cardiovascular and Renal Clinical Trialists (INI-CRCT), an international organization of academic cardiovascular and renal clinical trialists, held a meeting of regulators and experts in nephrology, cardiology, and clinical trial methodology. The group identified several research priorities, summarized in this paper, that should be pursued to advance the field towards achieving improved cardiovascular outcomes for these patients. Cardiovascular and renal clinical trialists must partner to address the uncertainties in the field through collaborative research and design clinical trials that reflect the specific needs of the chronic and end-stage kidney disease populations, with the shared goal of generating robust evidence to guide the management of cardiovascular disease in patients with kidney disease.
