Cook County Health also includes CountyCare, a Medicare managed care plan.

In 2001–2002, it moved into new quarters adjacent to its historic Beaux-Arts complex in the Illinois Medical District and was renamed for hospital board president John Stroger Jr. Stroger employs 300 attending physicians and over 400 fellows and residents.

Regarded as one of the world's greatest teaching hospitals, many interns, residents, and graduate physicians came to see the medical and surgical advances.

Innovations included the world's first blood bank and surgical fixation of fractures.

The former Cook County Hospital building was renovated and reopened as a privately funded mixed use development, and Hyatt Hotel.
