Duke Raleigh (NC) Hospital is preparing a long-range expansion plan that will continue transforming the hospital into a specialty medical campus. Initial plans, which the Duke health system board is expected to approve in January, call for expanding the Raleigh hospital's emergency department and operating rooms. Since the Duke University Health System bought the former Raleigh Community Hospital in 1998, it has pumped nearly $120 million into renovations and improvements at the facility, the Raleigh News & Observer reports.
