ANALYSIS OF THE EPIDEMIOLOGICAL PROFILE OF HOSPITALIZATIONS IN PUBLIC HEALTH SYSTEM OF BRAZIL FOR DEMENTIA BETWEEN 2019 AND 2021

Resumo

INTRODUCTION: Dementia is a clinical syndrome characterized by gradual cognitive decline, involving at least two cognitive domains, associated with impaired functionality. Dementias usually have a progressive course, which leads to disability in different timing and degrees, and is associated with infectious and vascular complications, which often lead these patients to hospital services. OBJECTIVE: To analyze the epidemiological profile of hospitalizations for dementia in the SUS in Brazil between the years 2019 and 2021. METHODS: The research is an observational and cross-sectional study of hospitalizations for dementia in the SUS in the years 2019 to 2021. The collection was carried out in the DATASUS database, with investigation of the variables: region, age group, gender, number of hospitalizations, total value, mortality rate and days of stay. RESULTS: In the period, there were 7908 hospitalizations with 56% of cases occurring in the Southeast. The largest shares of hospitalizations were between 60 and 69 years (16.7%), 70 and 79 years (23%), and more than 80 years (26.2%). The number of hospitalizations was highest in the first year, with 2963 cases, while it was lower in the following year with 2421 cases and 2524 in the third. The average values per hospitalization were R$5381, R$6323, and R$5847 in 2019, 2020, and 2021, respectively. Total costs were R$46M, mostly represented by the 40 to 49 year old age group, whose expenses were R$12.1M. The average mortality rate was 11.2% for the period, with higher rates in the Southeast. The group between 40 and 49 years had more days of hospitalization in each year, with 26.7% of the total, followed by the group over 80 years, which had 16.8% of the days. CONCLUSION: From the analysis of the number and mortality rate of cases, it is suggested that the long-term complications of dementias, which culminate in the hospitalization of these patients, are a major health problem, associated with high total costs and values per hospitalization still higher than the average monthly income for the period, and further studies are needed to measure the impact of the condition in the country. Furthermore, the preponderant regions were the Southeast and South, despite the population of the latter being smaller than the Northeast in numbers. Interestingly, it was shown that the groups with more hospitalizations did not correspond to higher total expenditures or length of stay, even when analyzing the year individually.
