This study is testing the impact of adding transcranial magnetic stimulation, a noninvasive technique that can reduce psychiatric symptoms associated with suicide risk, to brief cognitive behavioral therapy to reduce Veterans’ rates of suicide ideation and related behaviors. In 2020, there were 6,146 Veteran suicides, a rate 57% higher than that of non-Veteran U.S. adults. 4 Finding ways to enhance treatment efficacy for reducing suicide is critical. Brief cognitive behavioral therapy (BCBT) is a well-established and effective treatment that is widely implemented across VA healthcare systems, but not all patients respond to BCBT. Transcranial magnetic stimulation (TMS)—a noninvasive technique that can reduce psychiatric symptoms associated with suicide risk, including depression and PTSD—might be an optimal treatment to use in conjunction with BCBT. TMS is not associated with the systemic and costly side effects associated with medications used for these disorders. This ongoing study (May 2019–April 2024)—the first to examine the efficacy of combined treatment specifically for suicide prevention—is testing the effect of adding repetitive TMS to BCBT to reduce Veterans’ rates of suicide ideation and related behaviors. With a sample of Veterans hospitalized for suicide behavior, researchers will conduct a randomized controlled trial to evaluate the effect of adding a standard TMS course of treatment to BCBT to reduce suicide behaviors. Methods A total of 130 Veterans admitted to the psychiatric unit for suicide ideation or attempts will be randomized to active TMS plus BCBT or to sham TMS plus BCBT. Participants will be assessed at baseline, post-treatment, and six and 12 months post-hospital discharge. Efficacy of each program will be determined by examining a primary suicide composite outcome and several secondary outcomes, including suicide attempt, time to first attempt, number of re-hospitalizations and severity, and severity of suicide ideation. Analyses will help identify the types of patients who received the most benefit from the addition of TMS to BCBT for suicide. Findings are not yet available. Anticipated Impact If successful, this study will result in a combined treatment to decrease suicide ideation and related behaviors. Next steps could include dissemination and implementation throughout VA in coordination with local VISN and VA operations partners, and submittal of a partnered QUERI application.
