Toward Effective Utilization of the Pediatric Emergency Department: The Case of ADHD

This project's purpose was to characterize attention-deficit/hyperactivity disorder (ADHD)-related emergency department (ED) visits compared with other psychiatric visits made by children with Medicaid and to determine whether any visits were avoidable. Medicaid claims of children who visited the ED for mental health services were analyzed. Logistic regression was used to examine whether demographic, ED-, and system-level variables increased the odds of an ED visit for children with Medicaid, comparing those with ADHD to other psychiatric diagnoses. Children who were African American, arrived during the daytime, and lived in counties with mental health professional shortages had greater odds of an ED visit for ADHD compared to other psychiatric visits. Approximately 24% of all ED visits were for ADHD and about 30% of these visits may have been avoidable. ADHD-related ED visits comprise a sizeable proportion of all ED visits. Some visits appeared to be emergent but possibly treatable in primary care.
