A Health System/Community Partnership for Enhanced Outreach to Prevent Suicide Attempts

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to test an enhanced outreach intervention (EOI) delivered by Samaritans of Boston (a community organization that provides support during mental health crises) for people after they leave an emergency department (ED) visit for suicidal thoughts. The main questions it aims to answer are: Does the EOI reduce suicide-related behaviors? Does the EOI increase outpatient treatment attendance? Is the EOI acceptable and feasible? Can the EOI be delivered with fidelity by Samaritans? Participants will be randomized to the EOI plus care as usual or care as usual alone. Participants in the EOI plus care as usual group will: Receive outreach (by call or text) at a planned time once per week for the next 12 weeks. During these conversations, Samaritans staff will ask participants questions about their suicidal thoughts and behaviors, develop and review a list of coping skills to use if they have suicidal thoughts, and discuss plans for receiving mental health care. Receive caring messages from Samaritans staff at least once per week. Receive standard care that hospitals give for patients who present with suicidal thoughts. Be asked to complete monthly self-report questionnaires. For care as usual alone, participants will: Receive standard care that hospitals give for patients who present with suicidal thoughts. Be asked to complete monthly self-report questionnaires.

Detailed Description
-----------------
The period after discharge from an emergency department (ED) is a critical time of increased risk for suicide and related behavior (SRB). Brief caring contact interventions that provide follow-up and support after a healthcare visit have been shown to reduce SRB and are now recommended best practices for suicide prevention in healthcare systems. However, system- and individual-level barriers to widespread implementation exist. For example, deployment of brief contact interventions requires dedicated resources and staffing within already overburdened healthcare settings, and even single-session interventions require robust provider training and ongoing oversight for successful implementation. The purpose of this study is to evaluate a recently developed Enhanced Outreach Intervention (EOI) for post-ED discharge that combines multiple evidence-based suicide prevention components (e.g., safety planning, risk assessment, caring contacts, and care engagement) and is delivered through a partnership between a healthcare system (Mass General Brigham [MGB]) and a local crisis line organization (Samaritans of Boston). Combining multiple evidence-based interventions has the potential to increase effectiveness over usual practices, and partnering with a community organization vastly increases scalability. Samaritans staff will undergo robust, multifaceted training on the EOI, and use standardized decision trees to guide EOI delivery. The investigators will conduct a randomized controlled trial (N=300) of the EOI plus care as usual versus care as usual alone after ED discharge to test effectiveness of the EOI and collect data on implementation-related factors. The investigators will also explore potential moderators of intervention effects, including age, sex, race/ethnicity, and predicted risk of suicide attempt at baseline.

Design Details

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Effectiveness-implementation Hybrid Type 1 randomized trial. Participants will be randomized to EOI plus care as usual (CAU) or CAU alone using an equal (1:1) allocation ratio.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Enhanced Outreach Intervention plus Care as Usual (CAU)<br>Participants will receive the Enhanced Outreach Intervention (EOI) plus care as usual for 12 weeks after ED discharge. | Behavioral: Enhanced Outreach Intervention (EOI) plus Care as Usual (CAU)<br>* The EOI will contain four main components: safety planning, caring contacts, care engagement, and risk assessment. Outreach (via phone or text messaging) from Samaritans staff will be conducted every week of the 12 week intervention. Conversations will use a standardized phone script to (a) conduct a risk assessment, (b) develop and review a list of coping skills to use if the participant has suicidal thoughts, and (c) discuss plans for receiving mental health care. Samaritans staff will also send a caring text message or email at least once per week. Participants will also receive standard care that hospitals provide to patients who present with suicidal thoughts.<br>|
| Other: Care as Usual (CAU)<br>Participants will receive the standard care (i.e., CAU) that the hospital provides to patients who present with suicidal thoughts. | Other: Care as Usual (CAU)<br>* Participants will receive standard care that hospitals provide to patients who present with suicidal thoughts.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Suicide Attempts | Whether or not a suicide attempt occurs during the 12-week intervention period will be captured by manual review of electronic health records and the Self-Injurious Thoughts & Behaviors Interview (SITBI). | 4 weeks | 
| Number of Suicide Attempts | Whether or not a suicide attempt occurs during the 12-week intervention period will be captured by manual review of electronic health records and the Self-Injurious Thoughts & Behaviors Interview (SITBI). | 8 weeks | 
| Number of Suicide Attempts | Whether or not a suicide attempt occurs during the 12-week intervention period will be captured by manual review of electronic health records and the Self-Injurious Thoughts & Behaviors Interview (SITBI). | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Treatment Attendance | Treatment attendance during the 12-week intervention period will be captured by manual review of electronic health records and participant-reported outcome survey. | 4 weeks, 8 weeks, and 12 weeks | 
| Depressive Symptoms | Depressive symptoms will be measured using the Patient Health Questionnaire-9 (PHQ-9). The scale values ranges from 0 to 3. Higher total scores mean more severe symptoms. | Baseline, 4 weeks, 8 weeks, and 12 weeks | 
| Intensity of Suicidal Ideation | The intensity of suicidal ideation will be measured using the Beck Scale for Suicide Ideation (BSS). The scale values ranges from 0 to 2. Higher scores mean more intense suicidal ideation. | Baseline, 4 weeks, 8 weeks, and 12 weeks |
