This 21st US Renal Data System Annual Data Report covers data through 2007, and again includes a section on chronic kidney disease (CKD) in the United States. Using NHANES and employer group health plan data, we estimate the relationship between kidney disease markers and mortality risk and the likelihood of blood pressure and lipid control by CKD stage; illustrate use of the new ICD-9-CM CKD diagnosis codes; and report on morbidity, mortality, care and costs during the transition to ESRD. New chapters address CKD patient care, the transition to ESRD, and acute kidney injury.
In 2007, 111,000 patients started end-stage renal disease (ESRD) therapy, and the prevalent population reached 527,283 (including 368,544 dialysis patients); 17,513 transplants were performed, and 158,739 patients had a functioning graft at year’s end. Program expenditures reached $35.3 billion, with $23.9 billion from Medicare (accounting for 5.8% of total Medicare expenditures). The incident rate fell 2.1%, to 354 per million. Fistula use in prevalent patients declined 2.6 percent; catheter use continues to be a concern. The percentage of patients with hemoglobin levels above 13 g/dl has fallen since 2006, but levels in the incident population frequently exceed 12. First-year mortality and morbidity among hemodialysis patients—particularly the increasing rate of hospitalizations due to infections—continue to be major concerns, and pediatric patient survival has not improved. The public health impact of kidney disease is larger than previously appreciated, and early detection, education, intervention, and risk factor control need to address the heavy burden of cardiovascular disease and adverse events in this vulnerable population.
The staff at the US Renal Data System Coordinating Center is again grateful to the publisher of the American Journal of Kidney Diseases for the opportunity to present the Annual Data Report.
