According to recent data published by the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics, there were an estimated 1.4 million suicide attempts in the States in 2017 alone; and 47,173 Americans died by suicide during the same year. Firearms are the most common method of death by suicide, accounting for over half of all suicide deaths in 2017. Systematic approaches to suicide risk assessment, lethal means counseling, and prevention of firearm suicide are currently lacking. The 2012 National Strategy for Suicide Prevention calls for healthcare providers to counsel all patients at risk of suicide in the temporary reduction of access to firearms and other lethal means. In recent years, researchers and clinicians have developed the ?Lock to Live? decision aid. This tool has been used by healthcare providers in emergency departments as part of lethal means counseling among acutely suicidal adult patients with home access to firearms. While this decision aid has been studied in emergency department settings, there are no published articles reviewing its utility in the inpatient setting. Thus, the purpose of this study is to evaluate the feasibility, accessibility, and usefulness of the ?Lock to Live? decision aid with hospitalized adult firearm owners at increased risk of suicidality seen by our Psychiatry Consultation-Liaison inpatient service.
