Implementing the collaborative chronic care model for mental health: a nonrandomized clinical trial

Area of Science:

• Implementation science
• Mental health services research
• Healthcare quality improvement

Background:

• Collaborative Chronic Care Models (CCMs) are evidence-based for outpatient mental health.
• This study evaluated Implementation Facilitation (IF) versus Centralized Technical Assistance (CTA) for enhancing CCM-consistent care.
• The goal was to reduce mental health hospitalizations.

Purpose of the Study:

• To determine if IF enhances CCM-consistent care and reduces hospitalizations compared to CTA.
• To assess the impact of IF on team functioning in mental health clinics.
• To compare hospitalization rates between IF and CTA groups.

Main Methods:

• Stepped-wedge hybrid trial across eight VA medical centers (2022-2024).
• Included clinicians and 20,835 patients across 42 mental health teams.
• Measured CCM alignment via Team Development Measure (TDM) and mental health hospitalizations.

Main Results:

• Small, non-statistically significant improvements in Role Clarity and Team Primacy after IF (p=0.33, p=0.14).
• No significant difference in mental health hospitalization rates between IF and CTA sites.
• Team functioning at baseline was similar to post-implementation results from a prior trial.

Conclusions:

• IF showed minimal, non-significant improvements in team functioning for CCM-consistent practices.
• No difference in mental health hospitalization rates observed between IF and CTA.
• CTA may have already enhanced team functioning prior to the trial.
