Abstract

BACKGROUND: The Iowa Model is a widely used framework for the implementation of evidence-based practice (EBP). Changes in health care (e.g., emergence of implementation science, emphasis on patient engagement) prompted the re-evaluation, revision, and validation of the model. METHODS: A systematic multi-step process was used capturing information from the literature and user feedback via an electronic survey and live work groups. The Iowa Model Collaborative critically assessed and synthesized information and recommendations before revising the model. RESULTS: Survey participants (n = 431) had requested access to the Model between years 2001 and 2013. Eighty-eight percent (n = 379) of participants reported using the Iowa Model and identified the most problematic steps as: topic priority, critique, pilot, and institute change. Users provided 587 comments with rich contextual rationale and insightful suggestions. The revised model was then evaluated by participants (n = 299) of the 22nd National EBP Conference in 2015. They validated the model as a practical tool for the EBP process across diverse settings. Specific changes in the model are discussed. CONCLUSION: This user driven revision differs from other frameworks in that it links practice changes within the system. Major model changes are expansion of piloting, implementation, patient engagement, and sustaining change. LINKING EVIDENCE TO ACTION: The Iowa Model-Revised remains an application-oriented guide for the EBP process. Intended users are point of care clinicians who ask questions and seek a systematic, EBP approach to promote excellence in health care.
