This document discusses several models that guide the implementation of evidence-based practice. It describes models such as the Stetler Model, the Iowa Model, the Model for Evidence-Based Practice Change, the ARCC Model, PARIHS, the Clinical Scholar Model, and the Johns Hopkins Nursing Evidence-Based Practice Model. Each model outlines steps or phases for implementing evidence-based changes in practice and considers factors like evidence, context, and facilitation. Feedback loops and pilot studies are elements of some models, including the Iowa Model.
