Advocate Aurora Health is a not-for-profit, integrated health care network with some 500 care sites serving Illinois and Wisconsin. The organization includes about 30 acute and specialty care hospitals (including Advocate Christ Medical Center, Aurora St. Luke's Medical Center, Aurora Lakeland Medical Center, and Lutheran General Hospital) with more than 7,000 beds, as well as community health clinics, walk-in clinics (with Walgreen's), physician offices, and home health care and hospice agencies. The company was formed when Illinois-based Advocate Health merged with Wisconsin-based Aurora Health Care in 2018, creating one of the nation's largest not-for-profit health systems.
