Suicide prevention: a pragmatic review of recent studies.

Because of the almost complete absence of randomized controlled trials demonstrating the effectiveness of specific treatments, there is sometimes a degree of pessimism about our ability to prevent suicidal behaviors. However, the methodological challenges to produce such research are formidable and may never be overcome. Therefore, a pragmatic review of evidence-based methods of suicide prevention is required. This review of recent studies using a variety of research strategies, both nonpharmacological and pharmacological, particularly at the community level, provides persuasive data that suicide prevention is possible. This is achievable by the application of broad community and professional education programs, as well as by the optimum management of mental disorders.
