Clinical Characteristics Associated With Response and Remission From Depression Using Measurement-Based Care

Area of Science:

• Psychiatry and Mental Health

Background:

• Measurement-based care (MBC) is crucial for effective outpatient psychiatric treatment.
• Systematic symptom monitoring using tools like the Patient Health Questionnaire-9 (PHQ-9) enhances patient outcomes.
• Understanding factors influencing depression remission and response is vital for optimizing treatment.

Purpose of the Study:

• To identify factors associated with depression remission and treatment response using MBC.
• To analyze longitudinal changes in PHQ-9 scores in relation to treatment outcomes.
• To evaluate the impact of combined treatments and comorbidities on depression recovery.

Main Methods:

• Analysis of electronic health records from 4778 patients (aged 12+) in an academic outpatient psychiatry clinic.
• Inclusion criteria: baseline PHQ-9 score > 9 and at least one follow-up measurement.
• Cox regression models were used to assess factors associated with treatment response and remission, adjusting for covariates.

Main Results:

• Response and remission rates were 46.3% and 28.2%, respectively.
• Factors associated with response included combined treatment, follow-up PHQ-9 within 4-9 months, and absence of PTSD.
• Faster remission was linked to combined psychiatry-psychotherapy, timely PHQ-9 follow-up, lower baseline PHQ-9, and absence of PTSD.

Conclusions:

• Integrated psychiatry-psychotherapy approaches and regular symptom monitoring are key to improving depression outcomes.
• Addressing comorbid conditions like PTSD is critical for treatment success.
• MBC provides valuable data for evaluating treatment effectiveness and guiding clinical practice.
