To analyze the impact of the Collaborative Care Model (CoCM) on treatment outcomes for patients with varying severity of Major Depressive Disorder (MDD), particularly focusing on severe cases.
Approach:
Study Design: Retrospective observational analysis of 30,162 closed patient treatment episodes at Concert Health from 2018 to 2025, focusing on 5,693 patients with severe depression.
Data Analysis: Comparison of effect sizes for changes in PHQ-9 scores across severity levels and logistic regression to assess treatment factors and patient characteristics associated with treatment response and remission.
Key Findings:
Patients with severe depression had slightly lower odds of achieving treatment response compared to those with moderate depression (OR: 0.93).
Insurance type, suicide risk, anxiety presence, and care team engagement significantly influenced treatment response and remission.
Interpretation:
Limitations:
The study is observational and may not account for all confounding variables.
Results are based on a specific patient population within a telehealth setting, which may limit generalizability.
National survey data found lower per-capita representation across 23 occupations in nonmetropolitan communities, with the largest workforce differences observed among psychologists, physicians, and surgeons.
