REACH VET tied to fewer suicide attempts, not deaths

VA-authored triple-difference cohort study (173,313 veterans): REACH VET inclusion linked to more completed visits and safety plans and fewer admissions, ED visits and attempts; no mortality effect.

AI system

System

REACH VET (Recovery Engagement and Coordination for Health - Veterans Enhanced Treatment) suicide-risk predictive model and care-enhancement program

Model

The original REACH VET model used 61 variables selected from 381.

Release

The original model introduced in 2017.

Application developer

US Department of Veterans Affairs, Office of Mental Health and Suicide Prevention

Role

The model ranked patients by predicted suicide risk for clinical follow-up.

Configuration

The original 2017 REACH VET model selected 61 variables from 381. The later REACH VET 2.0 announcement concerns a different version.

Inputs and outputs

Not assessed

Autonomy

Not assessed

Workflow

A predictive model run monthly on VHA electronic health records to rank patients and select the top 0.1% risk tier. Facility REACH VET coordinators and providers who acknowledge the list, evaluate care, document safety plans and attempt outreach. A national health system with the data, dashboards and metrics to implement the program at every facility.

Human oversight

Not assessed

Relation to AI

The predictive model selects the monthly top 0.1% risk tier. Coordinators and providers then re-evaluate care and reach out, so the clinical response, not the model alone, produces any change. The evaluation is observational, uses a triple-difference design to handle non-parallel trends, and is authored by the VA office that built and runs REACH VET. It found no mortality association, replicated in 2025 by the same group. Independent reporting documents that the original model weighted being a white man heavily and omitted military sexual trauma.

Results

Result: suicide attempts (ADT, −0.05; 95% CI, −0.06 to −0.03).

Follow-up

Conditions for replication

Providers act on the list: care evaluations rose from 46.1% to 87.5% of identified veterans between March 2017 and December 2018. The model's variables fit the population; the original model under-weighted factors relevant to women veterans, per Nextgov. Outcome ascertainment is comparable across periods; the authors note that closer attention may increase recorded attempts.

Replication attempts

2 follow-up entries. Outcome unresolved: 2.

Later findings

17 July 2025. Nextgov reported in July 2025 that REACH VET still scans records monthly with the 61-variable model and that VA is updating it to a 2.0 model; a VA cohort study published 8 July 2025 found no association between REACH VET inclusion and suicide or all-cause mortality, in line with the 2021 evaluation's mortality subanalyses.

Reasons

People: The 2021 study reports population-level reductions in documented suicide attempts, admissions and ED visits for identified veterans. No individual veteran's outcome is documented, and mortality did not differ in 2021 or 2025. Organizations: Care evaluations rose from 46.1% to 87.5% of identified veterans and 98% were contacted by October 2020, per VA-authored papers. No independent audit was found. Society: Nextgov notes the top 0.1% tier covers only 2–3% of VA suicides and the model under-identified women; no population suicide-rate effect is shown.
