The Detroit Medical Center's owners met all of their community commitments except one under an agreement that accompanied the medical system's transition to for-profit ownership, an oversight board said in a final report to the state this week. The DMC Legacy Board, formed as part of a 10-year agreement reached as part of the health system's sale to Vanguard Health System Inc. a decade ago, reported to the Michigan Attorney General's Office that it was unable to monitor the quality of care at the health system, which has been owned by Tenet Healthcare since 2013. Tenet inherited the community commitments agreement when it bought Vanguard.
