A Propensity-Matched Retrospective Cohort Study of Antidepressant Drug Exposure and Risk of Suicide Attempt in Adults From a Large U.S. Managed Care Population

The primary objective of the study is to estimate the incidence of suicide attempts resulting in a medical encounter or hospitalization in seven propensity matched cohorts of subjects: patients treated with duloxetine for depression, patients treated with one of three other antidepressants or antidepressant classes (venlafaxine, SSRIs, or TCAs) for depression, patients treated with multiple antidepressants for depression (either concurrently or consecutively), depressed patients with no pharmacologic treatment, and a non-depressed general population sample.
