The U.S. Department of Veterans Affairs (VA) is shifting its focus from ending veteran homelessness to preventing veteran suicides. With supporting data, this Open Forum argues that VA homelessness services also help address veteran suicides. Analysis of a nationally representative survey of U.S. veterans in 2015 shows that veterans with a history of homelessness attempted suicide in the previous two years at a rate >5.0 times higher compared with veterans without a history of homelessness (6.9% versus 1.2%), and their rates of two-week suicidal ideation were 2.5 times higher (19.8% versus 7.4%). Because the majority of veterans who die by suicide are not engaged in VA care, VA services for the homeless that include outreach efforts to engage new veterans may be reaching some of these veterans. Thus continued federal support for VA homelessness services not only may help address homelessness but also may help prevent suicide of veterans.
