Emergency Department Means Restriction Education is an intervention for the adult caregivers of youth (aged 6 to 19 years) who are seen in an emergency department (ED) and determined through a mental health assessment to be at risk for committing suicide. Studies show that the presence of a gun in the household increases suicide risk, yet parents who take their adolescent to an ED for a suicide attempt are often not warned about restricting their child’s access to firearms and other lethal means. ED Means Restriction Education is designed to help parents and adult caregivers of at-risk youth recognize the importance of taking immediate, new action to restrict access to firearms, alcohol, and prescription and over-the-counter drugs in the home. The intervention also gives parents and caregivers specific, practical advice on how to dispose of or lock up firearms and substances that may be used in a suicide attempt. Examples are using firearm locking devices or locked medicine cabinets, turning in firearms to local police, or moving the item to another location outside the home. By encouraging reduced access to these means, the intervention also aims to lessen the risk of violence directed at others, including homicide.
