This quarterly report series examines the management of dialysis and mid- to late-stage chronic kidney disease (CKD) patients from the perspective of nephrologists. Emphasis is on renal anemia management (erythropoiesis-stimulating agents [ESAs], oral iron, and IV iron), calcium-phosphorus metabolism (phosphate binders), and secondary hyperparathyroidism (SHPT) (nutritional and active vitamin D and calcimimetic agents). The TreatmentTrends series provides longitudinal information on market dynamics. It provides insight into practice patterns, attitudes and perceptions, and current and projected use of various products. It evaluates perceived product advantages and disadvantages, as well as sales and messaging efforts, of key market players. The series continuously evolves and covers high-interest areas in the renal field, such as the impact of the dialysis bundle or coverage of late-stage products for the treatment of hyperkalemia.
