Incidence of mental health hospitalizations, treated self-harm, and emergency room visits following new anxiety disorder diagnoses in privately insured U.S. children.

Anxiety disorders are one of the most common mental illnesses in children and associated with high healthcare utilization. We aimed to estimate 2-year cumulative incidence of mental health-related hospitalizations, treated self-harm, and emergency room (ER) visits in children newly diagnosed with anxiety disorders and, for context, in children without anxiety disorders.
