Progress feedback models, including Feedback informed treatment (FIT), are evidence-based models for using client feedback to improve progress toward therapeutic goals in the behavioral health setting. These models are effective only when implemented with fidelity to the model. Local problem: A private Outpatient Clinic (OPC), with 23 clinicians serving over 1,000 clients, is in the process of implementing FIT, including a small pilot program of five clinicians. OPC did not have a systematic means of evaluating fidelity to the FIT model during this pilot program. This project uses the Conceptual Framework for Implementation Fidelity (CFIF) in conjunction with Plan-Do-Study-Act (PDSA) cycles of iterative improvement, as described by the Institute for Healthcare Improvement Model approach to Quality Improvement (IHI-QI). A process for evaluating and describing fidelity implementation of FIT during the pilot program, as well as eliciting clinician feedback on barriers to fidelity is described. A mixed-methods approach was used to collect quantitative data describing use of FIT tools over time with identified client population, and qualitative data from structured group interviews with participating clinicians. These data describe execution of the key fidelity components identified in this project. Evaluation included a description of fidelity to FIT at this early implementation stage and identified opportunities to improve fidelity moving forward.
