Reducing suicidal ideation in depressed older primary care patients

Area of Science:

• Geriatric Medicine
• Psychiatry
• Public Health

Background:

• Older adults are a vulnerable population for depression and suicidal ideation.
• Primary care settings are crucial for identifying and managing mental health conditions in the elderly.

Purpose of the Study:

• To evaluate the effectiveness of a primary care-based collaborative care program in reducing suicidal ideation among adults aged 60 and older with depression.
• To assess the long-term impact of this intervention on suicidal thoughts.

Main Methods:

• A randomized controlled trial involving 1,801 adults aged 60+ with major depression or dysthymia across 18 primary care clinics.
• The intervention group received collaborative care including a care manager for medication management and Problem Solving Treatment, while the control group received usual care.
• Suicidal ideation was assessed at baseline and 24 months using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (SCID) and the Hopkins Symptoms Checklist.

Main Results:

• At baseline, 15.3% of intervention participants and 13.3% of controls reported suicidal ideation.
• Significantly lower rates of suicidal ideation were observed in the intervention group at 6 months (7.5% vs. 12.1%) and 12 months (9.8% vs. 15.5%).
• These reductions were sustained at 18 months (8.0% vs. 13.3%) and 24 months (10.1% vs. 13.9%), with no completed suicides in either group.

Conclusions:

• Primary care-based collaborative care programs are effective in reducing suicidal ideation in older adults with depression.
• This model of care represents a viable strategy for mitigating suicide risk in elderly primary care patients.
• Further research should explore data on suicide attempts and hospitalizations to fully understand the intervention's impact on suicide prevention.
