Rapid national increases in the hospitalisation of Australian youth due to intentional self-harm between 2008 and 2019

Objective: Australian youth mental health services have received significant funding over the past 15 years. We analysed data on hospitalisation due to intentional self-harm to determine whether increased youth services were associated with reduction in a key indicator of youth population mental health. Method: Trends in national self-harm hospitalisation data from 2008 to 2019 for youth (25 years) were analysed using joinpoint regression. Results: Rates of hospitalisation due to intentional self-harm increased significantly in both male (1.1% per annum, 95% CI [0.2%, 1.9%]) and female (3.0% per annum, 95% CI [0.9%, 5.1%]) youth aged 25 years). Conclusions: Rates of hospitalisation due to intentional self-harm in Australian youth have increased despite significant investment in youth mental health services. This result could be attributable to several sociocultural factors and suggests a critical need for more hospital-based emergency youth mental health services.
