ABSTRACT

Background

This paper aims to highlight and analyze discrepancies in reporting of deaths due to venomous animals in Brazil, from 2001 to 2015, between two national information systems: The Notifiable Diseases Information System (Sistema de Informação de Agravos de Notificação – SINAN) and the Mortality Information System (Sistema de Informações sobre Mortalidade – SIM).

Methods

Descriptive and comparative study of the SINAN and SIM information systems, was conducted via the following steps: collecting the death notices from SINAN and SIM; constructing tables and comparative graphics; and, only in scorpion sting fatalities, analyzing the distribution of deaths by age group as described in the specialized literature.

Results

While SINAN identifies strong growth in the number of deaths from scorpion stings, SIM shows greater increase in the number of reported deaths from bee stings, especially in the South and Southeast regions. Notably, bees are the sole etiological agent that received more reports in SIM than in SINAN for every year in the period studied. The age-group distribution of the data on deaths from scorpion stings reinforced the indication of problems occurring in their registration in SINAN, especially since 2007, which may have an effect on analyses based on these data.

Conclusions

Comparative analysis of these databases permits identification of important differences between profiles presented by these systems, which have equal relevance for Brazil as a whole and for its regions. These differences may influence the construction of various scenarios.
