A promising strategy is to counsel patients seen in the emergency department (ED) for a psychiatric emergency to reduce access to firearms (the most lethal suicide method) and medications (the most common method of suicide attempt). To date, however, few studies have evaluated changes in firearm storage practices among those who received lethal means counseling (LMC), and those that have, including a pilot conducted in Colorado by the study team, have lacked control groups. Results from the pilot, which provided emergency department based LMC counseling to parents of suicidal adolescents, found that among gun-owning parents, 33% had unlocked guns at home on the day of the ED visit and none did on follow up.
