The Physician Engagement Maturity Model can help to frame up the steps to take in driving organizational change initiative. Physician engagement comprises three main aspects: fostering collaborative communications, developing shared outcomes, and defining and sharing metrics. The time to administering antibiotics greatly improved, and more patients survived. Moving from poor performance on a metric to formulary and practice changes that saved lives occurred because the task force was working at advanced stages of physician engagement. The maturity model is based on effective strategies within two domains: a Data-driven domain and an Engagement domain. The Data-driven domain is composed of Knowledge and Analytics subdomains. Understanding how sepsis mortality was dramatically reduced in just a few weeks was the foundation for this maturity model. The Physician Engagement Maturity Model is a road map for developing physician collaborations that drive successful interventions for patients and healthcare. Physician engagement with the whole community has never been more important than it is today.
