E-Mail NEW YORK, NY (Feb. 18, 2021)--A new study from Columbia University Vagelos College of Physicians and Surgeons has found that suicide mortality can be reduced by a Federally coordinated approach employing scientifically proven options. Columbia researchers J. John Mann, MD, Christina A. Michel, MA, and Randy P. Auerbach, PhD, conducted a systematic review, determining which suicide prevention strategies work and are scalable to national levels. The study, "Improving Suicide Prevention Through Evidence-Based Strategies: A Systematic Review," was published online in the American Journal of Psychiatry. The researchers found that screening school children or the general population for those at risk for suicide--the tenth leading cause of death in the U.S. with 48,344 suicide deaths in 2018--have generally not reduced suicide rates.
