Overview
Advocate Aurora Health was a nonprofit integrated health system serving patients primarily in Illinois and Wisconsin. It was created in 2018 through the combination of Illinois-based Advocate Health Care and Wisconsin-based Aurora Health Care. Its operations included hospitals, outpatient care, specialty services, emergency care, and other healthcare activities. The combination was intended to create a larger regional system and integrate clinical, administrative, and care-delivery resources. In 2022, Advocate Aurora Health combined with North Carolina-based Atrium Health to create Advocate Health. Advocate Aurora Health subsequently ceased operating as a standalone combined organization, with its institutions and activities incorporated into the new Advocate Health system. Reliable brand-level information about independent product naming, market positioning, and financial performance is limited, so this entry focuses on the organization’s basic history and service scope.
History
Advocate Aurora Health grew out of two predecessor nonprofit healthcare organizations: Advocate Health Care, primarily operating in Illinois, and Aurora Health Care, primarily operating in Wisconsin. The two organizations completed a combination in 2018 and formed Advocate Aurora Health, creating a nonprofit integrated health system serving patients across both states. The combined system continued to operate hospitals, outpatient facilities, specialty care, and emergency services while expanding and coordinating its regional care network. In 2022, Advocate Aurora Health combined with Atrium Health to establish Advocate Health. Following that combination, Advocate Aurora Health no longer continued as an independent system, and its facilities and services became part of Advocate Health.
