Predictive modeling can identify high-risk patients who were not identified on clinical grounds. VHA is developing modeling to enhance clinical care and to guide the delivery of preventive interventions.

IMPORTANCEThe Veterans Health Administration (VHA) implemented a national clinical program using a suicide risk prediction algorithm, Recovery Engagement and Coordination for Health-Veterans Enhanced Treatment (REACH VET), in which clinicians facilitate care enhancements for individuals identified in local top 0.1% suicide risk tiers. Evaluation studies are needed. OBJECTIVE To determine associations with treatment engagement, health care utilization, suicide attempts, safety plan documentation, and 6-month mortality. DESIGN, SETTING, AND PARTICIPANTS This cohort study used triple differences analyses comparing 6-month changes in outcomes after vs before program entry for individuals entering the REACH VET program (March 2017-December 2018) vs a similarly identified top 0.1% suicide risk tier cohort from prior to program initiation (March 2014-December 2015), adjusting for trends across subthreshold cohorts. Subcohort analyses (including individuals from March 2017-June 2018) evaluated difference-in-differences for cause-specific mortality using death certificate data. The subthreshold cohorts included individuals in the top 0.3% to 0.1% suicide risk tier, below the threshold for REACH VET eligibility, from the concurrent REACH VET period and from the pre-REACH VET period. Data were analyzed from December 2019 through September 2021. EXPOSURES REACH VET-designated clinicians treatment reevaluation and outreach for care enhancements, including safety planning, increased monitoring, and interventions to enhance coping. MAIN OUTCOMES AND MEASURES Process outcomes included VHA scheduled, completed, and missed appointments; mental health visits; and safety plan documentation and documentation within 6 months for individuals without plans within the prior 2 years. Clinical outcomes included mental health admissions, emergency department visits, nonfatal suicide attempts, and all-cause, suicide, and nonsuicide external-cause mortality. RESULTS A total of 173 313 individuals (mean [SD] age, 51.0 [14.7] years; 161 264 [93.1%] men and 12 049 [7.0%] women) were included in analyses, including 40 816 individuals eligible for REACH VET care and 36 604 individuals from the pre-REACH VET period in the top 0.1% of suicide risk.

BackgroundThe mood stabilisers lithium and valproate might plausibly have differing associations with mortality because of differing effects on mental health and various physiological indicators.AimsTo assess associations between lithium, valproate and non-suicide mortality.MethodIntention-to-treat, propensity score-matched cohort study.ResultsLithium was associated with significantly reduced non-suicide mortality in the intent-to-treat cohort over 0-90 days (hazard ratio (HR) = 0.67, 95% CI 0.51-0.87) but not longer. In secondary analyses, a sizeable reduction in mortality was observed during active treatment with lithium across all time periods studied (for example 365-day HR = 0.62, 95% CI 0.45-0.84), but significantly increased risks were observed among patients discontinuing lithium by 180 days (HR = 1.54, 95% CI 1.01-2.37).ConclusionsPatients initiating lithium had lower non-suicide mortality over 0-90 days than patients initiating valproate and consistently lower non-suicide mortality among patients maintaining treatment, but elevated risk among patients discontinuing treatment by 180 days. Although residual confounding or selection effects cannot be excluded, this study suggests potential benefits to enhancing lithium treatment persistence and the monitoring of patients discontinuing lithium. There is a need for further research.

Service use remained stable (80 percent) or increased (9 percent) for the vast majority of Veterans. Service utilization declined for only 11 percent. Data did not indicate substantial service discontinuation following rating. Low VHA service utilization suggests opportunities to enhance outreach for Veterans with PTSD-related disability benefits.

Objectives To assess outcomes for Veterans Health Administration (VHA) patients following calls to the Veterans Crisis Line (VCL). Methods 158,927 VHA patients had an initial VCL call in 2010–2015 with documented identifiers. Multivariable proportional hazards regressions assessed risks of suicide and suicide‐related behavior through 12 months. Covariates included age, sex, region, mental health encounters in the prior year, time of day, weekday/weekend status, call outcome, and responder determination of caller risk. Results Annualized suicide rates per 100,000 within 1, 3, 6, and 12 months were 797, 520, 387, and 298, respectively. Average age was 49.9 (SD = 15.2), 86.5% were male, 68.6% received mental health encounters in the prior year, and 5.9% had calls categorized as at high risk. Adjusting for covariates, suicide risk was greater among male callers and those with calls categorized as at high or moderate risk. Conclusions Veterans Crisis Line serves a high‐risk population at a critical time. Rates were particularly high within one month and remained substantially elevated through 12 months. Findings have directly informed ongoing efforts to enhance coordination between VCL and VHA to support suicide prevention.
