Exploration, Preparation, Implementation, Sustainment (EPIS) model (Conceptual Model of Evidence-based Practice Implementation in Public Service Sectors)
D and/or I:
The focus on dissemination and/or implementation activities. D-only focuses on an active approach of spreading evidence-based interventions to target audience via determined channels using planned strategies. D=I, D>I, and I>D means there is some focus on both dissemination and implementation. I-only focuses on process of putting to use or integrating evidence-based interventions within a setting.
The level of the framework at which the model operates. Individual includes personal characteristics; Organization includes hospitals, service organizations, and factories; Community includes local government and neighborhoods; System includes hospital systems and government; Policy includes changes in policy.
