DMC announced Wednesday that it wouldn’t be renewing its longstanding contract with the nonprofit Wayne State University Physician Group. The nonprofit employs nearly 300 doctors who teach and conduct research at the university while providing specialty care at DMC hospitals, which are owned by Dallas-based Tenet HealthCare.
