Análise temporal e distribuição espacial das internações hospitalares por queda de idosos no Brasil, entre 2009 e 2018

Abstract

Objective: To analyze the temporal trend and spatial distribution of hospital admissions due to falls in the elderly in Brazil. Method: Cross-­sectional population-based study based on data from the Informatics Department of the Unified Health System (DATASUS) and the Hospital Information System of the Unified Health System (SIH / SUS). Therefore, the data were collected in a secondary database. Data were extracted from the SUS Information System - DATASUS, and correspond to information referring to Hospital Admissions Authorizations - AIH, of elderly hospitalized for falls in the period from 2009 to 2018 in Brazil. Data analysis used resources from descriptive and inferential statistics. Terra View® programs were used for spatial analysis and Join point® for trend analysis. Results: Over the ten years studied, the trend of hospitalizations for the elderly as a result of falls has grown significantly by 1.2% per year in Brazil. Among the regions, this behavior was variable, with periods of growth and stationary, with significant hospitalization among all age groups of elderly people above 75 years old, and among women, also observing different patterns between each state. The spatial analysis showed a Moran Global index of 0.39 (p = 0.02) in the period from 2009 to 2013, showing the existence of spatial autocorrelation, with a grouping of three states with low-­low pattern, Pará, Amazonas and Amapá. Conclusion: Brazil is heading towards a new population configuration with an increase in the elderly population. The need to improve the structure of health care networks is urgent in all regions of the country in order to provide quick and effective care to the elderly victims of falls.
