Means restriction is the single most evidence-based suicide prevention intervention. Many suicide attempts are impulsive — the time from acute crisis to attempt can be minutes to hours. During that brief impulsive window, the availability of a lethal method is one of the most important determinants of whether the attempt is fatal. Reducing access during high-risk periods substantially reduces suicide deaths.
Ask specifically about access to means. "Do you have access to firearms at home?" "How much of [medication] do you have at home right now?" "Have you been thinking about a specific method?" The patient who plans to use a method they don't have access to is at lower acute risk than the patient with the means in hand.
The firearm conversation is the single most important means restriction discussion. Firearms account for approximately half of US suicide deaths and have the highest case-fatality rate of any method — most firearm suicide attempts are fatal. For the patient at elevated suicide risk with firearm access, the conversation isn't optional.
Negotiate, don't demand. "I'm not asking you to give it up forever. I'm asking you to put it somewhere you can't get to it quickly while you're going through this." Offer options: temporary storage with a family member or friend, a gun store or range that offers temporary storage, a locked safe with combination held by someone else, ammunition stored separately, gun locks. Acknowledge cultural value (firearm ownership has meaning for many patients), maintain the safety conversation.
Medication restriction. The patient with depression on lethal-in-overdose medications — TCAs, certain combinations — should not have weeks of supply at home during high-risk periods. Limited dispensing (1-2 weeks at a time). Family member or trusted person holds supply. Locked storage. Switch to less lethal alternatives if possible.
Verify the restriction occurred. Patients sometimes agree in the office but don't follow through. Follow up at the next visit. "Did your brother pick up the firearms? Is the medication locked?" Verification is part of the intervention.
Document the conversation — specifically what was discussed, what was agreed, what verification is planned. This is core safety work, and the chart should reflect that it happened.
