Study Suggests Social Stressors are Strongly Associated with Suicide Ideation and Attempt among Veterans


BACKGROUND:
The National Academy of Medicine recommended collection of social and behavioral determinants of health in 2014, including social stressors (i.e., homelessness, experiencing violence), which are linked to health in strong and complex ways. VA addresses some social stressors by screening all Veterans in VA care for homelessness and military sexual trauma and by offering vocational rehabilitation and supportive housing. However, there is scarce research on how a wider array of social stressors may be collected within VA's electronic health record (EHR), and how they might contribute to outcomes, such as suicidal ideation or suicide attempt. This observational study examined documented social stressors in VA's EHR and how these stressors were associated with suicidal ideation and suicide attempt. Investigators examined EHR data from October 2015 through September 2016 for 293,872 Veterans in VISN 4 with at least one inpatient or outpatient visit, assessing seven types of social stressors: 1) experiences of violence, 2) housing instability, 3) employment or financial problems, 4) legal problems, 5) social or familial problems, 6) lack of access to care or transportation, and 7) non-specific psychological needs. Also, because of the strong relation between mental illness and suicidal ideation and suicide attempt, investigators also accounted for whether Veterans were diagnosed with major depressive disorder, alcohol use disorder, drug use disorder, anxiety disorder, PTSD, schizophrenia, or bipolar disorder.

FINDINGS:

  • Social stressors were strongly associated with suicidal ideation and suicide attempt. For example, compared with Veterans who had no social stressors, those with one social stressor had nearly 2.5 times the odds of suicidal ideation, two social stressors had over four times the odds, three social stressors had nearly five times the odds, and four or more social stressors had over eight times the odds – after adjusting for numerous socio-demographic factors and mental illness diagnoses.
  • Overall, 16% of Veterans in this study had at least one social stressor in their EHR, and more than 16,000 had two or more.

IMPLICATIONS:

  • Social stressors are as relevant as biological factors (e.g., depression) for suicide prevention and treatment. Systematic assessment of a more complete set of these stressors may improve the ability to identify patients at highest risk of suicide.

LIMITATIONS:

  • Causality between social stressors and suicide morbidity could not be assessed because of the observational study design.
  • Investigators were unable to capture other potential social stressors (e.g., patient income).

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
