Michigan Medicine (University of Michigan Health System or UMHS from 1997 to 2017) is the academic medical center of the University of Michigan, a public research university in Ann Arbor, Michigan. Michigan Medicine includes the University of Michigan Medical School, with its faculty group practice and research laboratories; the university's affiliated hospitals and health centers, including the University of Michigan Hospital, C.S. Mott Children's Hospital, Von Voigtlander Women's Hospital, and approximately 40 health centers and home care services across southeast Michigan; the clinical programs of the University of Michigan School of Nursing; and the activities of the Michigan Health Corporation, through which U-M partners with other medical centers and hospitals to provide specialized care throughout Michigan. History In 1869 the University of Michigan opened the first hospital in the country owned and operated by a university, in a house in Ann Arbor originally built as a professor's residence. In 1876 a new hospital building was opened adjacent to the old one. At the insistence of the Michigan Legislature, the new building had two separate departments, one for medicine and the other for homeopathy. In 1891 the hospital moved to a set of new buildings away from the university campus, on Catherine Street. The homeopathy department closed in 1921. In 1925 the university opened a hospital building at a cost of $3.85 million. It was designed by Albert Kahn and built by Thompson-Starrett Company. In 1986 this building, known as "Old Main", was replaced by a new one farther away, and it was demolished in 1989. University of Michigan Rogel Cancer Center (formerly Comprehensive Cancer Center) was founded in 1986, and the Cardiovascular Center opened in 2007 on the site of the "Old Main" hospital. From 1986 to 2006, the health system included M-CARE, a managed-care organization that provided health plans to university faculty, staff, retirees, and dependents and to employees of companies throughout Michigan. In late 2006, it sold M-CARE to Blue Cross Blue Shield of Michigan and its Blue Care Network subsidiary to suffice the need for the health system focused on its core missions of patient care, research, and education. University of Michigan Health System was renamed Michigan Medicine in 2017. Overview Michigan Medicine is a high-volume surgical center with a total of 66 operating rooms. The construction of the $523 million Children and Women's Hospital and the $132 million Eye Center expansion added 18 operating rooms to
