The document discusses the four clinical teams needed to drive sustainable quality improvement: a leadership team, guidance teams, outcome improvement teams, and workgroups. It states that these permanent, cross-functional teams are critical to accelerating organizational change. The teams are involved in developing goals and aim statements, analyzing data to select improvement areas, gaining approval for recommendations, and establishing workgroups to implement improvements through an iterative process. Sustainable clinical process improvement requires investment in a deployment system using this team structure.
