Depression and comorbid panic in primary care patients

Area of Science:

• Psychiatry
• Primary Care Medicine
• Clinical Psychology

Background:

• Comorbid panic symptoms can complicate depression treatment.
• Evidence for panic symptom impact in primary care depression is limited.
• Most research on panic and depression is conducted in specialty care settings.

Purpose of the Study:

• To investigate the association between panic symptoms and depression treatment outcomes in a primary care setting.
• To evaluate the effectiveness of Selective Serotonin Reuptake Inhibitor (SSRI) treatment in patients with and without panic symptoms.

Main Methods:

• Analysis of data from a randomized trial of 573 primary care patients undergoing SSRI treatment for depression.
• Depression outcomes (remission, partial response, nonresponse) assessed at 6 months using the Symptom Checklist-20.
• Panic symptoms assessed via a screening question at baseline and monitored for persistence.

Main Results:

• Patients with baseline panic symptoms showed similar remission and partial response rates compared to those without.
• However, patients with persistent panic symptoms were significantly less likely to achieve depression remission (OR=0.38).
• Results were robust across different analytical methods and panic screening sensitivities.

Conclusions:

• Persistent panic symptoms are linked to poorer depression outcomes in the maintenance phase of treatment.
• Improving panic symptoms may be crucial for enhancing depression treatment success.
• Primary care physicians should consider panic symptom assessment in depression management.
