Objective:

To evaluate the effects of structured hospital-based psychosocial case management on suicidal thoughts and behaviors in patients with major depressive disorder (MDD) exhibiting active suicidal ideation or recent suicide attempts.

Approach:

Study Design: A multicenter, randomized clinical trial integrating structured care into national suicide prevention efforts in South Korea.

Key Findings:

The intervention did not significantly reduce suicide attempts compared to usual care.
Greater reductions were observed in overall suicidal thoughts, depressive symptoms, anxiety, and loneliness.

Interpretation:

The trial highlights the complexity of addressing suicidal ideation as a precursor to suicide attempts.

Limitations:

The trial did not show a significant reduction in suicide attempts between groups.
The absence of a behavioral signal does not negate the potential clinical relevance of the intervention.
