After initial treatment of only the most severely anemic patients, therapy was subsequently expanded to include most patients on dialysis and many nondialysis CKD patients. Many nephrology societies and regulatory agencies have sought to identify the most appropriate hemoglobin levels to which ESA therapy should be targeted. As increasing evidence became available about the impacts of ESAs on varying endpoints including morbidity, mortality, and quality of life, the guidelines put forth by such agencies evolved over time. We review the literature impacting these determinations through the past 3 decades and comment on how this informs the application of this knowledge to the care of patients today.enPublisher Policychronic kidney diseaseanemiaerythropoiesis-stimulating agentsArticle
