John H. Stroger, Jr. Hospital of Cook County

What John H. Stroger, Jr. Hospital of Cook County does

John H. Stroger, Jr. Hospital of Cook County is the flagship acute care hospital within Cook County Health, a public safety-net health system owned and operated by the Cook County government and serving the residents of Chicago and suburban Cook County, Illinois. The system provides comprehensive healthcare services regardless of insurance status or ability to pay, and has operated continuously for more than 180 years. The delivery network comprises two acute care hospitals (Stroger Hospital on Chicago's West Side and Provident Hospital on the South Side), a network of community health centers, the Ruth M. Rothstein CORE Center for HIV/AIDS and infectious disease, correctional health services at the Cook County Jail and Juvenile Temporary Detention Center, the Cook County Department of Public Health, and CountyCare — a Medicaid managed care plan.

The clinical platform centers on Stroger Hospital's role as the busiest Level 1 Trauma Center in Illinois, supported by Joint Commission Advanced Primary Stroke Center certification, advanced cardiac services including transcatheter aortic valve replacement (TAVR), robotic-assisted minimally invasive surgery, and a dedicated pediatric emergency department. Distribution extends to over 500,000 individuals annually through the combined provider and CountyCare health plan network, with the CountyCare plan providing access to 6,600+ primary care providers, 26,000+ specialists, 70+ hospital locations, and 150+ urgent care sites. Digital channels include the MyCookCountyHealth patient portal and ExpressCare virtual immediate care (operating 7am–7pm weekdays). CareLink serves as a free financial assistance program covering clinic visits, lab tests, hospital stays, and emergency services for uninsured or underinsured Cook County residents.

The business model is government-funded rather than commercially driven. Revenue is generated through CountyCare Medicaid managed care premiums, Medicaid and Medicare reimbursements for patient services, patient self-pay (with a 30% discount and Good Faith Estimates), and Cook County tax appropriations. The system reinvests surpluses into mission-driven services; it does not pursue profitability as a private-sector operator would. Staffing includes nearly 1,300 full-time nurses — the largest department — alongside a clinical and administrative workforce of 1,001–5,000. Quality is validated through Joint Commission accreditation, NCQA 4-star rating for CountyCare (2025, the highest in Illinois), Lown Institute #1 most racially inclusive hospital in Illinois (2024), and multiple American Heart Association Get With The Guidelines Gold Plus awards. No funding rounds, M&A, or private equity ownership exist; the entity is wholly government-owned.
