Suicide risk remission in collaborative care: a large-scale observational study

Area of Science:

• Behavioral Health
• Primary Care Medicine
• Suicidology

Background:

• Primary care is vital for suicide prevention, with many individuals interacting with providers before death.
• The Collaborative Care Model (CoCM) is a structured approach for behavioral health in primary care.
• Limited research exists on CoCM's effectiveness in managing suicide risk.

Purpose of the Study:

• To examine the relationship between clinical variables (enrollment duration, touchpoints, consultations) and suicide risk outcomes within CoCM.
• To investigate how initial depression severity moderates these relationships.

Main Methods:

• Analysis of data from 3,599 patients with suicide risk flags who completed CoCM.
• Ordinal logistic regression used to assess changes in suicide risk level (improved, unchanged, regressed).

Main Results:

• Longer enrollment and more clinical touchpoints significantly predicted improved suicide risk outcomes.
• Higher baseline depression scores predicted poorer outcomes but interacted with enrollment duration.
• Increased psychiatric consultations correlated with suicide risk regression, indicating appropriate case escalation.

Conclusions:

• CoCM demonstrates potential for suicide risk management in primary care settings.
• Sustained patient engagement and frequent clinical contact enhance treatment effectiveness.
• Tailoring treatment intensity based on initial depression severity is recommended for optimal results.
