Disparities in end-stage renal disease care in South America.

South America is one of the most heterogeneous regions in the world regarding ethnical composition and socioeconomic development level. Our aim was to analyze the status of end-stage renal disease (ESRD) management in the Portuguese-speaking and Spanish-speaking countries of South America. Data were collected using a survey sent to the Society of Nephrology of each country, and complemented with data available in the Latin American Dialysis and Transplant Registry or personal communication with collaborators within the nephrology societies. Most of South America countries have a hybrid of public and private healthcare system. Universal access to renal replacement therapy (RRT) is provided in Argentina, Brazil, Chile, Uruguay and Venezuela which comprise nearly 73% of South America population. The expenditure on health per capita varies from nearly US$ 200 per year in Bolivia to more than US$ 1,600 per year in Argentina. The prevalence of patients on RRT varies from 95 pmp. in Paraguay and 924 pmp in Chile. There is an important association between the prevalence of diabetes and the number of patients on RRT. Older people also are at a higher risk of developing ESRD. The rapid aging of the population and a higher prevalence of diabetes will probably translate into a burden of ESRD in the future. It is to be hoped that political and economical stability in the region can ease the adoption of universal access to ESRD treatment in all South American countries.
