Blueprint for design: creating models that direct change.

The need for healthcare system change is overwhelming: broken systems, an inadequate workforce, patient safety failures, and lack of access to healthcare are but a few of the significant problems confronting healthcare today. Most people agree that things need to change, but they are not sure on what to change or how to change them. A well-developed model can serve as the currency for that change. By considering the evidence of what has worked well in the past and marrying that with what the future will require, we can create a strong sustainable model for professional practice. The authors explore that evidence and discuss the structure, process, and outcomes that should be considered in designing care delivery models for the future.
