Mental health-related hospitalizations among adolescents and emerging adults with autism in the United States: A retrospective, cross-sectional analysis of national hospital discharge data.

Autistic young people are more likely to have mental health conditions, like depression and bipolar disorder, than people without autism. These mental health issues sometimes lead to hospitalizations, which can be expensive and traumatic. Because of this, we wanted to understand mental health-related hospitalizations among autistic young people aged 10-20. We found that the main mental health reasons for the hospitalization of autistic young people were neurodevelopmental, disruptive, depressive, and bipolar disorders. These hospitalizations cost an average of US$7401.23 per stay, for a total of US$106 million in service delivery costs in 2016. Mental health-related hospitalizations were compared between young people with autism, young people with complex and chronic conditions, and young people with no chronic conditions. Autistic young people were almost 11 times more likely to be hospitalized for mental health reasons than young people with complex and chronic conditions, and two times more likely than young people with no complex and chronic conditions. We believe the United States needs better community-based mental health care for young people with autism.
