title: Epidemiological trends in psychosis-related Emergency Department visits in the United States, 1992-2001.
abstract: Mental health visits represented an increasing fraction of all Emergency Department (ED) visits in the U.S. between 1992 and 2001. This study used the National Hospital Ambulatory Medical Care Survey, a 4-staged probability sample of ED visits from geographically diverse hospitals around the U.S., to assess the contribution of all psychosis-related visits to this overall trend. Unlike other mental-health-related ED visits, the rate of psychosis-related visits did not increase. This lack of change is notable in the context of dramatic changes in both healthcare financing and antipsychotic prescribing practices during this period. There was an unexpected decrease in Medicare-funded psychosis-related ED visits at a time of increasing Medicare enrollment overall. An important demographic trend over this decade was the increasing urbanization of psychosis-related ED visits coincident with a relative decrement in such visits within rural areas.
