About 21,000 suicides in the United States in 2014 involved a firearm. The authors reviewed evidence from around the world regarding the relationship between firearm ownership rates and firearm suicide rates and the potential effectiveness of policy-based strategies for preventing firearm suicides in the United States. ⋯ Broadly reducing availability and access to firearms has lowered firearm suicide rates in other countries but does not appear feasible in the United States. Approaches restricting access of at-risk individuals to already purchased firearms by engaging the public and major stakeholders require urgent implementation and outcome evaluation for firearm suicide prevention.
