Employment precariousness and the importance of the assessment of fatal occupational injuries on the Mortality Information System.

The research note entitled Assessment of incompleteness of Mortality Information System records on deaths from external causes in the state of Rio Grande do Sul, 2000-2019 1 presented results of an ecological time series study based on the analysis of deaths from external causes (ECs), specifically, from transport accidents, homicides, suicides and falls, occurred in Rio Grande do Sul, registered on the Mortality Information System ( Sistema de Informações sobre Mortalidade - SIM), between 2000 and 2019. There were discrepancies in the decreasing trends observed for sociodemographic variables among the alarming number of deaths analyzed (n = 146,882), according to causes of death.
