Implementation of Integrated Dual Disorder Treatment in Routine Veterans Health Administration Settings

Area of Science:

• Implementation Science
• Psychiatry
• Public Health

Background:

• Integrated dual disorder treatment (IDDT) coordinates care for severe mental illnesses (SMI) and comorbid substance use disorders (SUD).
• IDDT is evidence-based but faces implementation challenges in routine practice, particularly within the Veterans Health Administration (VHA).

Purpose of the Study:

• To identify critical factors influencing the implementation of IDDT within VHA settings.
• To document the costs associated with IDDT implementation efforts.

Main Methods:

• Qualitative study evaluating IDDT in four VHA programs across two medical centers.
• Utilized interviews and observations, with initial coding based on the Consolidated Framework for Implementation Research (CFIR).
• Cost analysis conducted at one VHA site.

Main Results:

• Perceived usefulness of the model, ongoing case-based coaching, staff receptiveness to stage-wise interventions, leadership support (team and management levels), and model adaptability were critical factors.
• Implementation costs were relatively modest.

Conclusions:

• Findings provide insights for future IDDT implementation within the VHA.
• Results are relevant to broader challenges in implementing complex mental health interventions in diverse service settings.
