Association of Suicide Prevention Interventions With Subsequent Suicide Attempts, Linkage to Follow-up Care, and Depression Symptoms for Acute Care Settings: A Systematic Review and Meta-analysis

Open access

Abstract

Importance: To prevent suicide deaths, acute care settings need tools to ensure individuals at risk of suicide access mental health care and remain safe until they do so. Objective: To examine the association of brief acute care suicide prevention interventions with patients' subsequent suicide attempts, linkage to follow-up care, and depression symptoms at follow-up. Data Sources: Ovid MEDLINE, Scopus, CINAHL, PsychINFO, Embase, and references of included studies using concepts of suicide, prevention, and clinical trial to identify relevant articles published January 2000 to May 2019. Study Selection: Studies describing clinical trials of single-encounter suicide prevention interventions were included. Two reviewers independently reviewed all articles to determine eligibility for study inclusion. Data Extraction and Synthesis: Two reviewers independently abstracted data according to PRISMA guidelines and assessed studies' risk of bias using the Cochrane Risk of Bias tool. Data were pooled for each outcome using random-effects models. Small study effects including publication bias were assessed using Peter and Egger regression tests. Main Outcomes and Measures: Three primary outcomes were examined: subsequent suicide attempts, linkage to follow-up care, and depression symptoms at follow-up. Suicide attempts and linkage to follow-up care were measured using validated patient self-report measures and medical record review; odds ratios and Hedges g standardized mean differences were pooled to estimate effect sizes. Depression symptoms were measured 2 to 3 months after the encounter using validated self-report measures, and pooled Hedges g standardized mean differences were used to estimate effect sizes. Results: A total of 14 studies, representing outcomes for 4270 patients, were included. Pooled-effect estimates showed that brief suicide prevention interventions were associated with reduced subsequent suicide attempts (pooled odds ratio, 0.69; 95% CI, 0.53-0.89), increased linkage to follow-up (pooled odds ratio, 3.04; 95% CI, 1.79-5.17) but were not associated with reduced depression symptoms (Hedges g = 0.28 [95% CI, -0.02 to 0.59). Conclusions and Relevance: In this meta-analysis, breif suicide prevention interventions were associated with reduced subsequent suicide attempts. Suicide prevention interventions delivered in a single in-person encounter may be effective at reducing subsequent suicide attempts and ensuring that patients engage in follow-up mental health care.

TL;DR

This systematic review and meta-analysis of 14 brief acute care suicide prevention interventions found that the pooled intervention effect was associated with fewer subsequent suicide attempts and greater linkage to follow-up mental health care, but not with significantly reduced depression symptoms at follow-up. The authors conclude these brief interventions may improve key outcomes after an acute care encounter, though suicide deaths were not examined.

Key findings

  • Subsequent suicide attempts: pooled OR, 0.69 (95% CI, 0.55-0.87); Hedges g = 0.21 (95% CI, 0.08-0.33); I² = 0%; P = .72. The paper reports this corresponds to a risk difference of -0.035, a 3.5% reduction, or 78 fewer suicide attempts in 2241 patients in the pooled intervention groups.
  • Linkage to follow-up care: pooled OR, 2.74 (95% CI, 1.80-4.17); Hedges g = 0.55 (95% CI, 0.32-0.78); I² = 55.4%; P = .02. The paper reports this corresponds to a 22.5% absolute increase in completed follow-up.
  • Depression symptoms at follow-up: Hedges g = 0.28 (95% CI, -0.02 to 0.59), not statistically significant; I² = 72.2%; P = .003. Excluding Asarnow et al resulted in a statistically significant pooled effect (Hedges g = 0.38 [95% CI, 0.05-0.71]).
  • Intervention components among 14 studies: brief contact in 6 (42.9%), care coordination in 3 (21.4%), Safety Planning Intervention in 5, and all but 1 study provided a brief therapeutic intervention. For linkage to follow-up care, the Peter test showed statistically significant evidence of small study effects (regression coefficient, 53.07 [95% CI, 10.47-95.66]; P = .02).

Methods

  • Systematic review and meta-analysis conducted per PRISMA, registered with PROSPERO (CRD42019114964). Searched Ovid MEDLINE, Scopus, CINAHL, PsychINFO, and Embase for English-language studies published January 1, 2000, to December 31, 2019.
  • Eligible studies examined an intervention delivered in a single in-person encounter to patients with identified suicide risk, included a comparison group, measured patient outcomes, and were available in English; interventions consisting solely of brief follow-up contact were excluded.
  • Random-effects models pooled outcomes for subsequent suicide attempts, linkage to follow-up care, and depression symptoms at follow-up. Analyses used pooled ORs and Hedges g, converted ORs to standardized mean differences, assessed heterogeneity with I², and conducted sensitivity and subgroup analyses; risk of bias was assessed with the Cochrane Risk of Bias tool.

Limitations

  • Paper-stated: the literature search was limited to published English-language articles and reports; unpublished findings were not included; only 14 studies were identified, with only subsets included in each meta-analysis; one large study (Miller et al, 2017) accounted for a large proportion of participants and was heavily weighted; and most studies did not include death as an outcome, so the review could not examine whether interventions reduced suicide deaths.
  • Evident from the text: several meta-analyses included few studies, heterogeneity was statistically significant for linkage to follow-up care and depression symptoms, and the linkage-to-follow-up analysis showed statistically significant evidence of small study effects, which the authors note could be a false positive or could reflect publication bias, selective reporting, or true heterogeneity.
  • Evident from the text: risk of bias was commonly high for incomplete outcome data, especially in studies that did not describe how missing data were analyzed.

  • The paper relies on this without support.

    Acute care settings, including hospitals, emergency departments, urgent care centers, jails, and shelters, lack enough specialty mental health clinicians and may be unable to provide continuous mental health care.

    “However, acute health care settings including hospitals, emergency departments, and urgent care centers as well as other settings that deliver acute suicide prevention services, such as jails and shelters, are not well staffed with specialty mental health clinicians and may not have the capacity to offer continuity of mental health care.”
  • The paper relies on this without support.

    Clinical teams require evidence-based interventions that directly address suicide risk and support patients' transition to continuing longitudinal mental health care.

    “To achieve these goals, clinical teams need evidence-based interventions to directly address suicide risk and to ensure that patients transition to ongoing, longitudinal mental health care.”
  • The paper relies on this without support.

    Acute care settings are on the front line of suicide prevention and need effective tools to lower patients' risk of suicide-related morbidity and death.

    “Nevertheless, these settings are at the front line of suicide prevention and require effective tools to reduce patients' risk of morbidity from suicide ideation and attempts and their risk of suicide death.”

    Reducing subsequent suicide attempts lowers the risk of suicide deaths.

    “Our findings provide important evidence that brief suicide prevention interventions may be effective at targeting important end points that reduce risk of suicide deaths.”
    “Suicide prevention interventions delivered during and after a single in-person acute care encounter may be effective at reducing subsequent suicide attempts and improving patients' odds of linkage to follow-up mental health care.”
  • The paper relies on this without support.

    Improving linkage to follow-up mental health care is beneficial for patients, for example by reducing suicide risk.

    “For linkage to follow-up care, the pooled OR was 2.74, which corresponds to a 22.5% absolute increase in rates of completed follow-up in patients receiving the intervention.”
    “Suicide prevention interventions delivered during and after a single in-person acute care encounter may be effective at reducing subsequent suicide attempts and improving patients' odds of linkage to follow-up mental health care.”

Each contradiction between two passages listed here was confirmed by an independent check.

  • Database-search count differs from the flow diagram

    Minor

    The results say database searches returned 3968 articles, whereas the flow diagram assigns 3964 records to database searching and 4 to other sources.

  • Care-coordination count omits a study marked in the table

    Minor

    The text identifies only studies 17, 19, and 20 as including care coordination, but the table also marks study 21 as having that component. That makes four studies rather than three.

  • Forest-plot caption calls Hedges g an odds ratio

    Minor

    The figure labels its plotted effects as Hedges g, but its caption says the vertical line shows a pooled odds ratio across all three outcomes. Depression is reported as Hedges g rather than an odds ratio.

  • Currier study has conflicting publication years

    Minor

    The depression forest plot labels Currier et al as 2019, while the study table labels the same cited study as 2010.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
