title: Deaths due to suicide: the effects of certification and coding practices in Australia.
abstract: OBJECTIVE
  To highlight issues relating to suicide coding that have an impact on the final reported mortality data by the Australian Bureau of Statistics.
  
  
  METHODS
  This paper presents an outline of the way in which the official Australian suicide data is captured and coded and highlights issues relating to the classification used, coronial processes, documentation requirements and data sources that have an impact on the final reported data, especially deaths associated with coronial investigations.
  
  
  RESULTS
  Issues related to the coding of Australian suicide data are: *Disparity between jurisdictions due to differences in documentation about accidental or undetermined causes of death. *Lack of standardisation in the way that coronial deaths are reported across Australia. *Lack of a standard form for police reports. *Administrative processes that cause delays in reporting the results of coronial investigations. *Reluctance on the part of some coroners to report deaths as suicides.
  
  
  CONCLUSIONS
  Researchers and policy makers need to be aware of the constraints under which suicide can be reported as such in the official data before interpreting time trends.
