This is the first overview report by the National Injury Surveillance Unit on national hospital separations due to injury and poisoning. The report focuses mainly on data for the financial year 1998-99.

'Separations' are not equivalent to newly incident cases that result in hospitalisation. This is because some incident cases result in more than one separation.

It should be noted that for 1998-99, NSW, Victoria, Northern Territory and the ACT coded data according to the 10th version of the International Classification of Diseases-Australian Modification.  The remaining four jurisdictions were still using the 9th version.
