Análises da completude e da consistência do Sistema de Informação sobre Mortalidade por CVLI na região Nordeste, Brasil, no período de 2010 a 2019

Abstract

The objective of this study is to analyze the completeness and consistency of data from the Mortality Information System (SIM) on deaths from violent and intentional lethal crimes (CVLI) in Brazil and in the Northeast region. The method chosen and used was an observational and descriptive study, based on secondary CVLI data from the SIM, referring to the period from 2010 to 2019. The consistency of the information and the percentage of non-completion of the characteristics of the victims, analyzed by through an incompleteness score proposed by researchers, where the information quality standard is considered excellent when the variable presents less than 5% of incomplete filling, good (5% to 10%), fair (10% to 20%), bad (20% to 50%) and very bad (50% or more). A total of 535,777 observations were analyzed, of which 54% (254,679 observations) had a sample loss resulting from incomplete data. The main losses are associated with the characteristics of occupation and education, which are fundamental for the design of public policies and for calculating the economic loss based on the potential years of lost lives. Therefore, consistent information and an improvement over the years in the completeness of the death certificate data was observed, however, further analysis is still needed so that all the characteristics of the victims are complete in the death certificates.
