EPIDEMIOLOGY AND MORTALITY OF THORACOLUMBOSACRAL SPINAL ARTHRODESIS IN BRAZIL: THE LAST 10 YEARS

Abstract

ABSTRACT Objective To describe the epidemiology and mortality of thoracolumbosacral arthrodesis surgery in Brazil in the last 10 years. Methods Study conducted using data from the SIH of the Unified Health System (SUS) covering the time period from 2008 to 2018 for all regions of Brazil. The data obtained were analyzed using the BioStat 5.3 program, using Chi-square statistical tests, observing a p-value <0.05 and a 95% confidence interval. Results A total of 66,631 anterior or posterior approach TLS surgeries were registered. The overall mortality rate was 9.37 deaths per thousand procedures. There are regions with mortality much higher than the national average. The mortality rate increases proportionally with the number of levels involved in posterior arthrodesis. Conclusions The study of the epidemiological profile of thoracolumbosacral arthrodesis is important, especially in a country whose population is heterogeneous but has different mortality rates among regions. Therefore, it is necessary to create measures that identify and prevent the factors that lead to the death of patients undergoing such a procedure. Level of evidence II; Retrospective, analytical, quantitative and descriptive study.
