Then, how do I conduct an evaluation, and what questions will it answer?

No worries.

Thanks for the information.

The next step is to design a study of the intervention’s implementation and—if you can include enough practices to potentially detect statistically significant changes in outcomes—a study of its impacts. Evaluations of interventions tested in a small number of practices typically can’t produce reliable estimates of effects on cost and quality, despite stakeholders’ interest in these outcomes. In such cases, you can use qualitative analysis methods to understand barriers and facilitators to implement the model and use quantitative data to measure interim outcomes, such as changes in care processes and patient experience, that can help identify areas for refinement and the potential to improve outcomes.
