Abstract

Objective:

to evaluate the incompleteness of Mortality Information System (Sistema de Informações sobre Mortalidade - SIM) data on deaths from external causes (ECs) in the state of Rio Grande do Sul, Brazil, 2000-2019.

Methods:

This was an ecological study, using SIM data on all deaths from external causes and, specifically, from transport accident, homicides, suicides and falls; the analysis of the trend of incompleteness was performed by means of Prais-Winsten regression, with a 5% significance level.

Results:

A total of 146,882 deaths were evaluated; sex (0.1%), place of death (0.1%) and age (0.4%) showed the lowest incompleteness in 2019; the proportion of incompleteness showed a decreasing trend for the place of death and schooling, an increasing trend for marital status and a stable trend for age and race/skin color, among all types of death evaluated.

Conclusion:

the variables analyzed reached a high degree of completion; with the exception of marital status and schooling, for which unsatisfactory scores persisted for deaths from ECs, both total and by subgroups.
