Five years from now, the Detroit Medical Center hopes, an infusion of $1.5 billion will turn it into a premiere medical center, such as the Cleveland Clinic. A proposed deal with Tennessee-based Vanguard Health Systems provides $850 million for new investments. DMC CEO Mike Duggan said 40% of the system's potential customers bypass its Detroit hospitals for suburban facilities with more modern amenities. He hopes to use the investment to lure them back with world-class facilities at the DMC.
