Use of capture-recapture method to improve the notification of fatal occupational injuries records in Belo Horizonte city, Minas Gerais State, Brazil, 2011.

OBJECTIVE
to measure underreporting of typical fatal occupational injuries (FOI) on the Mortality Information System (SIM) in Belo Horizonte city, Minas Gerais State, Brazil, in 2011.


METHODS
the capture-recapture method was used to assess all FOI recorded among city residents and/or occurring in the city, using probabilistic linkage of three data sources: SIM, the Notifiable Diseases Information System (SINAN) and the Belo Horizonte Forensic Medicine Institute Autopsy Database.


RESULTS
the majority of the 54 cases found occurred in males (n=53), with drivers and construction workers accounting for half of them (n=28); the most common causes of death were traffic accidents (n=18) and falls (n=10); 15 deaths were underreported on SIM.


CONCLUSION
the use of the capture-recapture method contributed to the detection of FOI underreporting.
