[Erythropoietin use by incident hemodialysis patients in the Brazilian Unified National Health System, 2002-2003].

This study aimed to describe the demographic and epidemiological profile of Brazilian patients entering hemodialysis from 2002 to 2003 and identify predictors of erythropoietin use. The study analyzed demographic and clinical characteristics and dialysis facility-related variables from 32,136 patients identified by deterministic-probabilistic matching in the database of authorizations for high-cost procedures and the Mortality Information System. Poisson regression was used to identify predictors of erythropoietin use. Male gender, age < 65 years, diabetic renal failure, arteriovenous fistula at the beginning of hemodialysis, and living in States of Brazil other than Mato Grosso were predictors of erythropoietin use. The policy of care for chronic kidney disease, resource allocation for States and municipalities, and anemia management according to the patient's drug therapy profile need to be revised in order to reduce observed inequities in erythropoietin use.
