Emergency Department Visits Related to Mental Health Conditions

This indicator shows the rate of emergency department visits related to mental health disorders* (per 100,000 population). Mental health problems can place a heavy burden on the healthcare system, particularly when persons in crisis utilize emergency departments instead of other sources of care when available. In Maryland, there were 161,208 mental health disorder-related emergency department visits in 2010.

*Diagnoses include adjustment disorders, anxiety disorders, attention deficit disorders, disruptive behaviour disorders, mood disorders, personality disorders, schizophrenia and other psychotic disorders, suicide and intentional self-inflicted injury and miscellaneous mental disorders.
