Adults who engage in deliberate self-harm often repeat the behavior. Using violent methods, particularly firearms, significantly increases suicide risk, especially shortly after the initial event.

Area of Science:

  • Public Health
  • Psychiatry
  • Epidemiology

Background:

  • Deliberate self-harm is a significant public health concern.
  • Understanding risk factors for repeat self-harm and suicide is crucial for intervention.

Purpose of the Study:

  • To identify risk factors for repeat self-harm and completed suicide within one year among adults diagnosed with deliberate self-harm.

Main Methods:

  • A national cohort of 61,297 Medicaid-financed adults with deliberate self-harm was followed for up to one year.
  • Repeat self-harm and suicide rates were determined using Cox proportional hazard models.

Main Results:

  • The rate of repeat self-harm was 263.2 per 1,000 person-years; suicide rate was 439.1 per 100,000 person-years.

  • Violent self-harm methods, especially firearms, significantly increased suicide hazard (HR=15.86).
  • Recent outpatient mental health care was associated with a slightly increased suicide hazard (HR=1.6).

    • Conclusions:

    • Adults treated for deliberate self-harm have a high likelihood of repeat self-harm.
    • Violent methods, particularly firearms, indicate an exceptionally high suicide risk, necessitating careful assessment and close follow-up.
