Completeness of notifications of accidents involving venomous animals in the Information System for Notif iable Diseases: a descriptive study, Brazil, 2007-2019

Abstract

Objective: to describe the completeness of notif ications of accidents involving venomous animals held on the Notif iable Health Conditions Information System (SINAN), in Brazil and its macro-regions, f rom 2007 to 2019. Methods: we analyzed essential and non-mandatory f ields for snakebite, spider bite and scorpion sting notif ications, considering the following completeness categories: Excellent (≤5.0% incompleteness), Good (5.0% to 10.0%), Regular (10.0% to 20.0%), Poor (20.0% to ≤50.0%) and Very Poor (>50.0%). Proportional change in completeness between 2007 and 2019 was estimated. Results: 1,871,462 notif ications were investigated. The “localized manifestations”, “systemic manifestations”, “case classif ication”, “case progression” and “zone of occurrence” f ields had excellent or good completeness. Completeness was regular or poor for the “schooling” and “race/color” f ields. The “occupation” f ield was predominantly poorly or very poorly f illed in. There was a proportional worsening in completeness (PC<0) in most regions for the “zone of occurrence”, “case progression” and “schooling” f ields. Conclusion: completeness of most f ields improved, although socioeconomic and occupational f ields require more attention.
