Qualidade dos dados do sistema de informação sobre acidentes de trabalho com exposição a material biológico no Brasil, 2010 a 2015

Abstract

Background: Health information systems allow for the identification of problems in this field, and often represent the single source of information; therefore, accurate determination of their quality is crucial. Aims: To analyze accessibility, opportunity and completeness as criteria for the quality of the information provided by System of Information for Notifiable Conditions (Sistema de Informação sobre Agravos de Notificação - SINAN) on Work Accidents under Exposure to Biological Materials (Acidentes de Trabalho com Exposição a Material Biológico - ATEMB) from 2010 to 2015. Methods: Observational and descriptive study based on secondary SINAN data on ATEMB. The object of analysis was all ATEMB records from the 26 Brazilian states and Federal District from 1 January 2010 to 31 December 2015. Results: Information is accessible and timely, while the data for the ongoing year are only made available the following one. The percentage of incomplete data in SINAM-ATEMB was high for the following variables: educational level, length of work in the current job, organic materials, serological status of affected individuals and source-patient, measures adopted, case progression and Work Accident Notification (Comunicação de Acidente de Trabalho - CAT); therefore, these variables cannot be included in analyses of risk factors. Conclusion: Despite the accessibility of the database and the relevance of its variables, SINAN-ATEMP exhibits problems in its quality that indicate an indisputable need to improve the completeness of information.
