Primary Outcome Measures

Name	Time	Method
District Health Board level suicidal behaviour including: the annual rate per 100,000 persons of intentional self-harm and self-inflicted death. Intentional self-harm is assessed using presentations to emergency departments identified from electronic databases and medical records. Self-inflicted death is assessed using coroner's data from the Coronial Services of New Zealand. [25 month intervention period from 1st June 2010 to 30 June 2012.]

Secondary Outcome Measures

Name	Time	Method
Suicidal behaviour by the following population subgroups:<br>Males age 20-60.<br>Maori. <br>Maori males 20-60<br>Suicidal behaviour will include all presentations for Intentional Self-harm (ISH) to Emergency Departments in the 8 DHB regions for attempted suicide and self-harm. ISH will be measured as the number of identified ISH events in the ED data (as the numerator) relative to DHB population sizes (as the person-time denominator). The person-time used in the denominator will be derived from census data for the DHBs in the study. Rates of self-inflicted deaths, which will include all completed (and suspected) suicides (i.e. excluding self-harm which does not result in death) will be requested from the Coronial Services of New Zealand. ISH will be used as the marker of effect on suicidal behaviours because the number of self-inflicted deaths is too small to use as the main outcome measure alone, leading to insufficient power to be confident of detecting a difference.[Same. 25 month intervention period.]
