STAR*D: helping to close the gap between science and practice

Area of Science:

• Clinical Psychology
• Psychiatric Research
• Public Health Policy

Background:

• Traditional randomized controlled trials (RCTs) have limitations in reflecting real-world clinical practice.
• The STAR*D (Sequenced Treatment Alternatives to Relieve Depression) trial was designed as a practical clinical trial to address these limitations.

Purpose of the Study:

• To evaluate the effectiveness of a stepped-care approach in treating major depression in a real-world setting.
• To assess remission rates and identify factors associated with treatment success or failure.

Main Methods:

• The STAR*D trial enrolled a large, diverse patient population with major depressive disorder.
• Participants received sequential treatment with different antidepressant medications, including augmentation and switching strategies.
• Remission was defined as a score below a certain threshold on a depression rating scale.

Main Results:

• The STAR*D trial achieved a 70% remission rate among participants.
• Achieving remission often required medication switching or augmentation, indicating the need for flexible treatment strategies.
• A significant portion of participants (30%) did not achieve remission, and high attrition rates were observed.

Conclusions:

• Practical clinical trials like STAR*D are valuable for understanding depression treatment in real-world conditions.
• Accessible and diverse treatment options, including medication adjustments, are crucial for improving depression remission rates.
• Future research should prioritize patient involvement in trial design and interpretation, and address high attrition rates.
