ABSTRACT
INTRODUCTION: Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity. OBJECTIVE: This study linked different data sources to measure the numbers of deaths and serious injuries and to estimate the percentage of corrections regarding the underlying cause of death, cause of injury, and the severity injury in victims in matched pairs from record linkage in five representative state capitals of the five macro-regions of Brazil. METHODS: This cross-sectional, population-based study used data from the Hospital Information System (HIS), Mortality Information System (MIS), and Police Road Traffic database of Belo Horizonte, Campo Grande, Curitiba, Palmas, and Teresina, for the year 2013 for Teresina, and 2012 for the other capitals. RecLink III was used to perform probabilistic record linkage by identifying matched pairs to calculate the global correction percentage of the underlying cause of death, the circumstance that caused the road traffic injury, and the injury severity of the victims in the police database. RESULTS: There was a change in the cause of injury in the HIS, with an overall percentage of correction estimated at 24.4% for Belo Horizonte, 96.9% for Campo Grande, 100.0% for Palmas, and 33.2% for Teresina. The overall percentages of correction of the underlying cause of death in the MIS were 29.9%, 11.9%, 4.2%, and 33.5% for Belo Horizonte, Campo Grande, Curitiba, and Teresina, respectively. The correction of the classification of injury severity in police database were 100.0% for Belo Horizonte and Teresina, 48.0% for Campo Grande, and 51.4% for Palmas after linkage with hospital database. The linkage between mortality and police database found a percentage of correction of 29.5%, 52.3%, 4.4%, 74.3 and 72.9% for Belo Horizonte, Campo Grande, Palmas, Curitiba and Teresina, respectively in the police records. CONCLUSIONS: The results showed the importance of linking records of the health and police databases for estimating the quality of data on road traffic injuries and the victims in the five capital cities studied. The true causes of death and degrees of severity of the injuries caused by RTC are underestimated in the absence of integration of health and police databases. Thus, it is necessary to define national rules and standards of integration between health and traffic databases in national and state levels in Brazil.

Objetivo: descrever os óbitos por acidentes e por violências relacionadas ao trabalho e verificar a aplicabilidade da autópsia verbal para melhoria da qualidade da informação sobre esses óbitos no município de Palmas, Estado do Tocantins, Brasil, em 2010 e 2011. Métodos: estudo descritivo de série de casos, sobre óbitos por acidentes e violências relacionados ao trabalho entre trabalhadores com 18 anos ou mais de idade, com dados do Sistema de Informações sobre Mortalidade (SIM) e investigação mediante autópsia verbal. Resultados: dos 74 óbitos investigados, 14 foram relacionados ao trabalho, dos quais 4 foram por acidentes típicos, 5 por acidentes de trajeto, 2 não puderam ser classificados e 3 foram resultantes de violências relacionadas ao trabalho; a subnotificação de acidentes fatais no SIM foi 100 por cento. Conclusão: os óbitos por causas relacionadas ao trabalho não eram identificados na declaração de óbito e a autópsia verbal mostrou-se aplicável para aprimorar as informações sobre esses óbitos no SIM.
Objective: to describe deaths from work-related accidents and violence in Palmas-TO, Brazil, 2010-2011 and to verify the applicability of verbal autopsy for improving the quality of information on such deaths. Methods: descriptive case series study of deaths from work-related accidents and violence in workers aged 18 or over using Mortality Information System (SIM) data and investigation through verbal autopsy. Results: 14 of the 74 deaths investigated related to work. 4 of them were typical accidents, 5 resulted from commuting injuries, 2 could not be classified and 3 resulted from work-related violence. Fatal injuries at work were 100 per cent underreported on the SIM. Conclusion: workrelated deaths were not identified on death certificates and verbal autopsy proved to be instrumental in enhancing information about such deaths on the SIM.

Objetivo: descrever os acidentes de trabalho (AT) fatais no Estado do Tocantins, Brasil, e avaliar a qualidade das informações contidas no Sistema de Informações sobre Mortalidade (SIM). Métodos: estudo ecológico descritivo com dados do SIM, no período 2000-2010. Resultados: foram identificados 400 óbitos por AT, com predomínio de trabalhadores do sexo masculino, entre 20 e 49 anos de idade, ocupados nos setores agropecuário, dos transportes e da construção civil; o coeficiente de mortalidade manteve-se estável (p=0,56) no período, equivalente a 6,7 e 9,6/100 mil trabalhadores, em 2000 e 2010, respectivamente; apesar da diminuição da proporção de óbitos por causas mal definidas (de 21,1 por cento em 2000 para 2,7 por cento em 2010), a completitude da informação sobre a relação do óbito com o trabalho permaneceu inferior a 20 por cento no período. Conclusão: o perfil apresentado pode não refletir o real universo dos óbitos por AT, evidenciando a necessidade de aprimorar a qualidade da informação.
Objective: to characterize fatal occupational accidents in the Brazilian State of Tocantins and evaluate Mortality Information System (SIM) information quality. Methods: descriptive ecological study of SIM data between 2000 and 2010. Results: 400 fatal occupational accidents were reported in this study, predominantly males aged 20 to 49 working in the farming, transport and civil construction sectors. The mortality coefficient was stable (p=0.56) in the period at 6.7 and 9.6/100,000 workers in 2000 and 2010 respectively. Despite the reduction in the proportion of deaths with ill-defined causes, the completeness of information on the relationship between death and occupation remained below 20 per cent in the period. Conclusion: the profile found may not reflect the actual universe of fatal occupational accidents, demonstrating the need to improve information quality.
