Path 2 facilitates multi-center quality improvement projects between collaborating centers in good standing in the Pediatric Acute Care Cardiology Collaborative. Interested individuals apply for Path 2 approval from the Quality Improvement Committee and invite 3-5 centers to participate in shared QI testing and learning. Before approval, projects must establish a SMART aim, a key driver diagram, operational definitions measures and baseline data. PAC³ anticipates supporting two Path 2 projects annually. Participating centers are expected to establish a QI champion, participate in monthly team meetings and provide a quarterly report of progress. Completed work is recommended for submission for presentation at national meetings.
