Abstract:To support veterans at high risk for suicide, the Veterans Health Administration (VHA) developed a suicide risk prediction algorithm and implemented the Recovery Engagement and Coordination for Health–Veterans Enhanced Treatment (REACH VET) program. It identifies VHA patients at high risk for suicide (top 0.1% risk tier), providing outreach and care coordination. An effectiveness evaluation of the REACH VET program documented reductions in nonfatal suicide attempts but did not identify associations with suicide mortality. Those mortality analyses were limited to a 6-month period for a subset of the study cohort. This study evaluates the association of REACH VET with mortality outcomes through 24 months for an expanded cohort.
