There are many theories, models, and frameworks that have been proposed in the field of implementation science. Despite this, many evidence implementation or practice improvement projects do not consider these theories, models, or frameworks in their improvement efforts. The JBI approach is one example of an implementation theory, model, or framework. This approach has been developed particularly with health care professionals in mind and is designed to clearly guide pragmatic evidence implementation efforts based on the best available evidence. In this paper, we discuss how the JBI approach to evidence implementation can interact with and support theory-informed, pragmatic evidence implementation projects.
