Background: Stroke is the second leading cause of mortality worldwide, being preceded only by ischemic heart diseases, 85% of these deaths occur in developing countries. Objective: To analyze the temporal behavior of elderly mortality due to stroke in Brazil, regions and federation units from 2008 to 2019. Methods: Ecological study of time series using Brazil, its regions and federation units as units of analysis. The following categories were collected on the DATASUS online platform :, :, i) length of stay, ii) average length of stay (days), iii) number of deaths, and hospital mortality rate from 2008 to 2019 for Brazil, regions and federative units. In the analyzes, the inflection point regression model was used, the 95% confidence interval and the significance level of 5% (joinpoint regression model) were adopted and the annual percentage change (Annual Percent Change - APC) was calculated. and the entire period (Average Annual Percent Change - AAPC). Results: As for Brazil, there was an average of 7.5 days per hospital stay and a hospital mortality rate corresponding to 16.6%. Among the regions, the highest gross numbers were evidenced in the Southeast with 4427093 days of stay, 7.73 days on average of stay and 99753 deaths. A decrease was observed only in the hospital mortality rate in the South (AAPC: -1.3 CI: -1.9 to -0.7), Southeast (AAPC: -1.3 CI: -1.7 to -0.9) and Northeast (AAPC: -0.7 CI: -1.4 to -0.0) and the average hospital stay for the Southeast (AAPC: -0.7 CI: -1.3 to -0.1). Conclusion: There was a heterogeneous behavior of the variables related to the mortality of elderly people due to stroke in Brazil, in parallel to the stationary behavior of the average hospitalization observed in the regions and units of the federation with the exception of the Southeast, which showed a decrease in the average days spent in study period.
