Emergency department presentations with a mental health diagnosis in Australia, by jurisdiction and by sex, 2004-05 to 2016-17.

The proportion of ED presentations for MH conditions, narrowly defined, has increased in all Australian jurisdictions between 2004-05 and 2016-17, but particularly since 2010-11. Differences between jurisdictions indicate jurisdictional specific issues. However, significant or upward trend of MHdx presentations across all jurisdictions indicates generic issues necessitating concern and policy development at a national level.
