Did you know that nearly 1/8 of all emergency department visits in the US are because of a mental disorder, substance abuse problem or both? A new federal report found that depression and other mood disorders accounted for 43% of behavioral health visits, 26% were for anxiety disorders and 23% involved alcohol-related problems. These data are from AHRQ News and Numbers in their Mental Health and Substance Abuse-Related Emergency Department Visits among Adults, 2007 report.
