Officials at Atlanta's Grady Memorial Hospital have set a target date of May 20 to transfer control of the hospital to a nonprofit corporation. The heads of the old Grady board and the new nonprofit have both agreed to the date for changeover in control. But some outstanding issues remain: Pam Stephenson, the head of the old Grady board, said that board is concerned about the amount of funding that the state will provide Grady. Hospital board members had expected the transfer of control would be met with additional long-term state aid for statewide trauma care that would go to Grady. But the Georgia Legislature has ended its session without approving long-term trauma funding.
