Two competing metro Detroit hospital systems are moving forward with new, smaller versions of once-shelved plans for suburban expansion. The three-hospital Beaumont Health System recently dusted off a 5-year-old plan for constructing a North Pavilion addition at its main campus in Royal Oak with a new emergency room department. At the same time, the Detroit Medical Center plans to build a $42-million children's outpatient specialty center in Troy. The future Children's Hospital of Michigan Specialty Center-Troy would be built in lieu of DMC's now-canceled $50-million Royal Oak outpatient center that was to serve both children and adults.
