Disposição histórica das internações por Acidente Vascular Cerebral Isquêmico no Nordeste brasileiro entre 1999-2019

The aim of this study was to analyze the historical disposition of hospitalizations for ischemic stroke and their hospital characteristics over the last 20 years in northeastern Brazil, hypothesizing the impact of the creation of national public policies. This is a retrospective ecological study of time series between 1999–2019 based on data collected in the Hospital Information System of the SUS. The data were stratified by sex and age group. There was a significant reduction in the number of hospitalizations, total value (cost), and number of deaths between the years 2001–2002 and 2013–2014; the other years show similar constancy. The same variables increased with age, but were found to be equivalent between genders. The data studied for IS showed a sharp decline between 2002 and 2014. Numerous factors might have influenced this change in behavior, including the implementation of programs such as Hiperdia and Mais Medicos.
