Mental health disorders are the most common chronic conditions experienced by young people in the developed world and are a significant burden to public health in Australia1,2. Additionally, many mental health disorders of adulthood have their onset in childhood or adolescence3.
In recent years, the number of young people presenting to emergency departments with mental health conditions has steadily increased4. The most common nature of presentation is for intentional self-harm4. Other common presentations are for substance abuse, and mood, behavioural, or emotional disorders4.
Understanding the proportion of paediatric presentations to ED that are because of mental health has important implications for policy and service delivery4. Geographic statistics can provide insight into where hospitals need to be better equipped to effectively deal with mental health presentations and where non-hospital services have not been sufficient to meet the needs of individuals experiencing mental health conditions. They can also indicate where mental health and health service education may be lacking, leading individuals to present to an emergency department rather than an alternative service that may be better suited to their needs.
Understanding the prevalence of mental health emergency department presentations in young people is therefore useful for informing effective policy to improve the outcomes of young people across the state.
