Trends in US Emergency Department Visits for Suicide Attempts, 1992–2001

Abstract

This article describes trends in suicide attempt visits to emergency departments in the United States (US). Data were obtained from the National Hospital Ambulatory Medical Care Survey using mental-health-related ICD-9-CM, E and V codes, and mental-health reasons for visit. From 1992 to 2001, mental-health-related visits increased 27.5% from 17.1 to 23.6 per 1000 (p < .001). Emergency Department (ED) visits for suicide attempt and self injury increased by 47%, from 0.8 to 1.5 visits per 1000 US population (p(trend) = .04). Suicide-attempt-related visits increased significantly among males over the decade and among females from 1992/1993 to 1998/1999. Suicide attempt visits increased in non-Hispanic whites, patients under 15 years or those between 50-69 years of age, and the privately insured. Hospitalization rates for suicide attempt-related ED visits declined from 49% to 32% between 1992 and 2001 (p = .04). Suicide attempt-related visits increased significantly in urban areas, but in rural areas suicide attempt visits stayed relatively constant, despite significant rural decreases in mental-health related visits overall. Ten-year regional increases in suicide attempt-related visits were significant for the West and Northeast only. US emergency departments have witnessed increasing rates of ED visits for suicide attempts during a decade of significant reciprocal decreases in postattempt hospitalization. Emergency departments are increasingly important sites for identifying, assessing and treating individuals with suicidal behavior.
