Background:
Studying stroke rates in a whole community is a rational way to assess the quality of patient care and primary prevention. However, there are few studies of trends in stroke rates worldwide and none in Brazil.
Objective:
Established study methods were used to define the rates for first ever stroke in a defined population in Brazil compared with similar data obtained and published in 1995.
Methods:
All stroke cases occurring in the city of Joinville during 2005-2006 were prospectively ascertained. Crude incidence and mortality rates were determined, and age adjusted rates and 30 day case fatality were calculated and compared with the 1995 data.
Results:
Of the 1323 stroke cases registered, 759 were first ever strokes. The incidence rate per 100 000 was 105.4 (95% CI 98.0 to 113.2), mortality rate was 23.9 (95% CI 20.4 to 27.8) and the 30 day case fatality was 19.1%. Compared with the 1995 data, we found that the incidence had decreased by 27%, mortality decreased by 37% and the 30 day case fatality decreased by 28%.
Conclusions:
Using defined criteria we showed that in an industrial southern Brazilian city, stroke rates are similar to those from developed countries. A significant decrease in stroke rates over the past decade was also found, suggesting an improvement in primary prevention and inpatient care of stroke patients in Joinville.
