Model and approach for assessing implementation context and fidelity in the HEALing Communities Study

Area of Science:

• Public Health
• Implementation Science
• Health Services Research

Background:

• The U.S. faces a severe opioid epidemic, necessitating innovative community-level interventions.
• The HEALing Communities Study (HCS) is a large-scale trial addressing this crisis.
• The study focuses on the Communities That HEAL (CTH) intervention to reduce opioid overdose deaths.

Purpose of the Study:

• To test the novel Communities That HEAL (CTH) intervention in 67 communities.
• To expand integrated evidence-based practices (EBPs) across healthcare, behavioral health, justice, and community settings.
• To evaluate the implementation context and fidelity of the CTH intervention.

Main Methods:

• Utilizing the RE-AIM/PRISM framework for capturing implementation context and evaluating fidelity.
• Employing repeated annual surveys and qualitative interviews with community stakeholders.
• Measuring fidelity through constructs like dosage, adherence, quality, and program differentiation, alongside monthly tracking of activities and training.

Main Results:

• The study systematically examines implementation context and fidelity in a community-level cluster-randomized trial.
• It assesses the relationship between implementation context, fidelity, and intervention impact.
• Findings will advance the understanding of how to best evaluate community-level implementation of EBPs.

Conclusions:

• Increasing the adoption of EBPs in communities is crucial for addressing the opioid epidemic.
• The HCS provides valuable insights into the complexities of community-level implementation research.
• This research will significantly enhance the evaluation of EBPs and their impact in real-world community settings.
