UCI Health Integration Timeline
Led by the UCI Health Integration Management Office (IMO), we are working to bring together our teams to offer better care than ever in Orange County and beyond.
Integration has three main phases: Pre-Day 1 for planning and preparing, First 100 Days to focus on stabilizing our new system, and Years 1-3 to focus on long term integration.
Throughout the process, our focus is to predict and plan for system continuity and protect patient care and clinical quality, prioritize and pivot to a longer-term integration strategy and vision over time, creating sustainable system performance.
As the only academic health system in Orange County, UCI Health is dedicated to the discovery of new medical frontiers, to the teaching of future healers and to bringing the finest evidence-based care to you and our community.
