North Carolina regulators have rejected plans by WakeMed and Rex Healthcare to continue building satellite campuses in rapidly growing sections of Wake County. The proposals would have brought urgent care centers and other services to the North Carolina communities of North Raleigh, Cary, Holly Springs and Garner. State analysts questioned hospital officials' projections that involve market share and the rate at which services would be used. They also suggested that the areas where the construction was proposed were already adequately served.
