Lithium for Suicidal Behavior in Mood Disorders

Purpose

Observational evidence and findings from clinical trials conducted for other reasons suggest that lithium, a drug used for the treatment of bipolar disorder, and, to a lesser extent, depression, may reduce rates of suicides and suicide attempts. However, this hypothesis has not yet been adequately examined in a randomized clinical trial conducted specifically to test lithium's efficacy in preventing suicides. This clinical trial fills this gap. This study is feasible within the Department of Veterans Affairs (VA) because it is a large, integrated health system with existing programs for identifying patients at risk for suicide and delivering enhanced services. In VA, approximately 12,000 patients with depression or bipolar disorder survive a suicide attempt or related behavior each year, and 15% of them repeat within one year. Experimental treatment in this study will supplement usual care for major depression or bipolar disorder, as well as VA's standard, enhanced management for patients at high risk. The investigators will recruit 1862 study participants, from approximately 30 VA Hospitals. Participants will be patients with bipolar disorder or depression who have survived a recent episode of suicidal self-directed violence or were hospitalized specifically to prevent suicide. Randomly, half will receive lithium, and half will receive placebo. Neither the patients nor their doctors will know whether a particular person has received lithium or placebo. The treatment will be administered and the patients will be followed for one year, after which patients will go back to usual care. Recruitment will occur over 3 years. The investigators are primarily interested in whether lithium leads to increases in the time to the first repeated episode of suicidal behavior, including suicide attempts, interrupted attempts, hospitalizations specifically to prevent suicide, and deaths from suicide. In addition, this study will allow us to explore whether lithium decreases the total number of suicidal behaviors, and whether it has comparable effects on impulsive and non-impulsive behaviors. If there is an effect of lithium, the investigators will be interested in whether or not it could be attributed to improved control of the underlying mental health condition, or, alternatively, whether it represents a direct effect of suicide-related behavior.
