The study objective was to evaluate the temporal tendency of the final cost of renal replacement therapy and also to evaluate the ratio between a procedure cost and its requests on the High Complexity Outpatient Procedures Authorization/Cost in the city of Rio de Janeiro, between 1995 and 2009 in totals and as the second provider. In this quantity, grade, descriptive and retrospective study, we used information about the values and quantities of high-complexity procedures licenses for renal replacement therapy each year, available on DATASUS, collected between February and March of 2011. An increasing trend was observed for the total cost and authorizations for high-complexity procedures for RRT (y = 3.8414 x + 16.904, R ² = 0.9665 and y = 14519x + 299719, R ² = 0.8835, respectively). There is a statistically significant difference (p <0.001) in the range of trend, when comparing public and private institutions. The main conclusion is that there is a tendency to book a large number of services and procedures in public hospitals, which increases the need of qualified professionals to work in the area.
