Summary

This study tests whether a 12-week outreach program from a community crisis support group can reduce suicide attempts in people who recently visited an emergency department for suicidal thoughts. Participants will receive weekly phone or text check-ins, safety planning, and caring messages, plus standard care. The goal is to see if this extra support lowers suicide-related behaviors and improves attendance at follow-up mental health appointments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Enhanced Outreach Intervention (phone/text safety planning, caring contacts, risk assessment)
What this could lead to
If it works, this could provide a simple, scalable way to prevent suicide attempts in people leaving the emergency room.
What could go wrong
This is a relatively small trial (300 people) testing a behavioral intervention, not a drug. Results may not apply to everyone, and the effect may be modest.
