This literature review examines the evidence that the proportion of all suicide attempts ending in a completed suicide (the case fatality ratio) accounts for a major portion of the variation in suicide mortality. In the US, the case fatality rate is strongly related to the prevalence of household firearms. Over twenty years of ecologic and individual-level studies support the hypothesis that reducing access to lethal means is an effective suicide prevention strategy.
